Someone please help me asap. I’m confused and need help. Complete the table using the function n = 9b + 19
Answers
answer: you would just substitute all of the values you see for b into the equation where there's a b
Answer:
55; 64; 73
Step-by-step explanation:
In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19
if b = 4:
n = 9(4) + 19
n = 36 + 19
n = 55
if b = 5:
n = 9(5) + 19
n = 45 + 19
n = 64
if b = 6:
n = 9(6) + 19
n = 54 + 19
n = 73
Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it
if b = 7:
n = 9(7) + 19
n = 63 + 19
n = 82
Work is correct
Try not to overthink it ^-^

It was right on delta math
The isotope samarium-151 decays into europium-151, with a half-life of around 96.6 years. A rock contains 5 grams of samarium-151 when it reaches its closure temperature, and it contains 0.625 grams when it is discovered.
The time since the rock reached its closure temperature is _____
years. When the rock was discovered, it had _____
grams of europium-151.
Answers
Answer:
See explanation
Step-by-step explanation:
Mass of samarium-151 originally present (No) = 5 g
Mass of samarium-151 discovered (N) = 0.625 grams
time taken = ?
half life of samarium-151 (t1/2) = 96.6 years
From
N/No = (1/2)^t/t1/2
0.625/5 = (1/2)^t/96
0.125 = (1/2)^t/96
1/8 = (1/2)^t/96
(1/2)^3 = (1/2)^t/96
3 = t/96
t = 3 * 96
t = 288 years
The mass of europium-151 when the rock was discovered is obtained from;
Fraction of samarium-151 left = 1/8
Fraction of europium-151 formed = 1 - 1/8 = 7/8
Mass of europium-151 = 7/8 * 5 = 4.375 g

x₂ = [7 -7 -6 1]
We have to produce the orthogonal basis for w using the Gram-Schmidt process;
Here,
y₁ = x₁ = [1 -4 0 1]
Now,
Solve for y₂
y₂ = x₂ - [x₂y₁ / y₁y₁] y₁

y₂ = [7 -7 -6 1] - ( [7 -7 -6 1] [1 -4 0 1] / [1 -4 0 1] [1 -4 0 1] ) × [1 -4 0 1]
y₂ = [7 -7 -6 1] - (7 + 28 - 0 + 1) / (1 + 16 + 0 + 1) × [1 -4 0 1]
y₂ = [7 -7 -6 1] - 36/18 × [1 -4 0 1]
y₂ = [7 -7 -6 1] - 2 × [1 -4 0 1]
y₂ = [7 -7 -6 1] - [2 8 0 2]

Assuming that the x-axis tick marks will be separated by 5 (5, 10, 15, and so on), what is the largest value that should appear on the x-axis
Answers
The largest value that should appear on the x-axis assuming that the tick marks will be separated by 5 is 95.
Since the tick marks are separated by 5, we can start with the smallest tick mark at 0 and add 5 for each subsequent tick mark.
To determine the largest value that should appear on the x-axis, we need to find the largest multiple of 5 that is less than or equal to the largest value in the data set. In this case, we don't have any information about the data set, so we can't determine the largest value.
However, we can assume that the x-axis should be long enough to accommodate the largest value that we expect to see. If we assume that the largest value is 100, then the largest multiple of 5 that is less than or equal to 100 is 95.
Therefore, the largest value is 95.

based off of this information, what conclusions can be made about the mean value theorem? this contradicts the mean value theorem since f satisfies the hypotheses on the given interval but there does not exist any c on (1, 4) such that f '(c)
Answers
The correct option is; 4: this contradicts the Mean Value Theorem since there exists a c on (1, 7) such that f '(c) = f(7) − f(1) (7 − 1) , but f is not continuous at x = 3.
Explain the term Mean Value Theorem?The Mean Value Theorem says that there occurs a point c in the interval (a,b) so that f'(c) equals the function's average rate of change throughout [a,b] if a function f is continuous just on closed interval [a,b] as well as differentiable just on open interval (a,b).The function being used is;
f(x) = (x - 3)⁻²
If we separate this function according to x, we obtain;
f'(x) = -2/(x - 3)³
Finding all c values f(7) − f(1) = f '(c)(7 − 1).is our goal.
This suggests that;
0.06 - 0.25 = -2/(c - 3)³ x 6
-0.19 = -12/(c - 3)³
(c - 3)³ = 63.157
c = 6.98
If the Mean Value Theorem holds for this function, then f must be continuous on [1,7] and differentiable on (1,7).
But when x = 3, f is not continuous, hence the Mean Value Theorem's prediction is false.

How many mil For Company A to have a better deal, the truck must be driven more than miles per day.
Answers
To make Company A a better deal, the truck must be driven more than 200 miles per day.
To determine which company offers a better deal, we need to compare the total cost for renting the truck from each company. Company A charges $120 per day plus $0.20 per mile, while Company B charges $40 per day plus $0.60 per mile.
Let's assume the number of miles driven per day is represented by 'x'. For Company A, the total cost would be $120 (fixed daily rate) plus $0.20 (cost per mile) multiplied by 'x' (number of miles). So the total cost for Company A would be $120 + $0.20x.
For Company B, the total cost would be $40 (fixed daily rate) plus $0.60 (cost per mile) multiplied by 'x' (number of miles). Hence, the total cost for Company B would be $40 + $0.60x.
To find the point at which Company A becomes a better deal, we need to set up an inequality. We want the total cost for Company A to be less than the total cost for Company B, so we can write the inequality as:
$120 + $0.20x < $40 + $0.60x
Now we can solve this inequality to find the threshold for 'x', which represents the number of miles driven per day that makes Company A the better deal.
120 - 40 < 0.60x - 0.20x
80 < 0.40x
200 < x
Therefore, the truck must be driven more than 200 miles per day for Company A to offer a better deal compared to Company B.

Similarly, converting between units can be very important, and it can be done by canceling units. For example, suppose that I want to convert 66 feet/second into miles per hour. If I know that there are 5280 feet in a mile, 60 seconds in a minute, and 60 minutes in an hour, then I can convert the quantity by multiplying it by those conversion factors in such a way that they cancel: ( 1 s
66ft )( 1 min60 s )( 1hr 60 min )( 5280ft1 mile )=45mile/hr I can do this because each conversion factor is equal to one, and multiplying by one does not change anything. Notice that if you cancel all the units that you can, you are left with the desired units. The numbers are evaluated with normal arithmetic. Cglints = 1 filn 4 ZCOS=1 strord Now you try, except I'm going to make up some fictional units for you to work with: There are 12 grees in a zool. There are 2 grees in 10 twibbs. There are 5 grees in a blob. There are 6 glints in a filn. There are 4 zools in a strord. 12 grees =1 ZOO 2 grees =10 twibs 5 grees =1 bic (a) Convert the quantity 7 glint/twibb (i.e., 7 glints-per-twibb) into filn/strord (i.e., filns-per-strord). As always, show your work. (b) Often we use prefixes for scientific units. For example, there are one-hundred centimeters in a meter. Similarly, the prefix kilo- means a factor of 10
3. For example, a kilometer is 10 3 meters or 1000 meters. If you need to review these prefixes, there is a handy chart on Wikipedia: ht tpa://en.wikipedia.org/wiki/Metric_prefix. Convert your answer from part (a) into megafiln/strord (i.e., megafilns-per-strord). (Hint: Check your answer for plausibility. Should the number of megafilns-per-strord be bigger or smaller than the number of filns-per-strord? If someone is going 1 foot-per-hour, are they going a larger number of feet-per-hour or a larger number of miles-per-hour?)
Answers
The number of megafilns-per-strord should be smaller than the number of filns-per-strord since a mega is a conversion factor of 10³ and is greater than 1, hence 1 megafiln is greater than 1 filn.
(a) The given units can be converted as follows: 6 glints = 1 filn...
(1)12 grees = 1 zool...
(2)2 grees = 10 twibbs...
(3)5 grees = 1 bic...
(4)Note that the grees are in both the numerator and denominator of the second unit conversion factor (3). Hence we can cancel out the grees by using it twice in the numerator and denominator. Now using the given conversion factors in equation (1), we get:
7 glint/twibb=7 glint/ (10 grees/2 grees)=14 glint/10 grees=14 glint/ (5 grees/12 grees)=16.8 filn/strord
(b) We need to convert the result of part (a) from filn/strord to megafiln/strord.
1 mega = 106
Thus 1 megafiln = 106 filn
16.8 filn/strord = (16.8 filn/strord) x (1 megafiln/106 filn) = 1.68 x 10-5 megafiln/strord
The number of megafilns-per-strord should be smaller than the number of filns-per-strord since a mega is a factor of 10³ and is greater than 1, hence 1 megafiln is greater than 1 filn. Similarly, going 1 foot-per-hour would mean going a smaller number of feet-per-hour than going 1 mile-per-hour since there are 5280 feet in a mile.

One car left a city at 2:00 PM and traveled at an average speed of 40 miles per hour. A second car left at 4:00 PM, traveled the same route and overtook the first car at 9:00 PM. What was the average speed in miles per hour of the second car
Answers
The average speed of the second car was 60 miles per hour.
1. Let's calculate the time difference between when the first car started and when the second car caught up. The second car started two hours after the first car, therefore it travelled for five hours (9:00 PM - 4:00 PM).
2. We know that the first car traveled for a longer period than the second car, as it started at 2:00 PM and was overtaken at 9:00 PM. Therefore, we need to find the total distance traveled by the first car during this time.
Time traveled by the first car = (9:00 PM - 2:00 PM) = 7 hours.
The first car's speed is 40 miles per hour.
Distance travelled by the first automobile = Speed Time = 40 mph per hour 7 hours = 280 miles.
3. Since the second car caught up with the first car, we can conclude that the distance traveled by the second car is equal to the distance traveled by the first car, which is 280 miles.
4. We know that the second automobile drove for 5 hours. 280 miles is the distance travelled by the second automobile. The second automobile travelled for 5 hours.
5. To get the average speed of the second vehicle, divide the distance travelled by the time required: The second car's average speed = Distance Time = 280 miles 5 hours = 56 miles per hour.
As a result, the second car's average speed was 56 miles per hour.

Answers
The solution to the system of equations is (-2, 2).
Given that the graph shows a system of equations, we need to draw a line labeled y = x + 4 by joining the ordered pairs (-4, 0) and (1, 5). We also need to draw a line labeled 3y = -2x + 2 by joining the ordered pairs (-2, 2) and (4, -2).
Now, to find the solution to the system of equations, we need to identify the point where these two lines intersect.
This point will represent the solution to the system of equations. We can find this point by solving the two equations simultaneously.
Using the first equation, y = x + 4, we can substitute this value of y into the second equation, 3y = -2x + 2, to get:3(x + 4) = -2x + 2 Simplifying this equation, we get:3x + 12 = -2x + 2 5x = -10 x = -2Substituting this value of x back into the first equation, y = x + 4, we get:y = -2 + 4 y = 2

Find the value of the indicated trigonometry ratio cos in right tringle with side of 6,6*squort 2, 6*squort 3
Answers
Answer:√2/2
Step-by-step explanation:
Let's label the sides of the right triangle as follows:
The side adjacent to the angle θ (cosine is adjacent/hypotenuse): 6
The hypotenuse (the longest side): 6√2
The side opposite to the angle θ (sine is opposite/hypotenuse): 6√3
Using the Pythagorean theorem, we can find the length of the missing side:
a² + b² = c²
6² + (6√3)² = (6√2)²
36 + 108 = 72
144 = 72
√144 = √72
12 = 6√2
Now that we know the length of all three sides, we can use the cosine ratio to find the value of cos(θ):
cos(θ) = adjacent/hypotenuse = 6/6√2 = √2/2
Therefore, the value of cos(θ) in the right triangle with sides of 6, 6√2, and 6√3 is √2/2.
Question 4 [14 marks] Let Y₁. , Y₁ denote a random sample from the probability density function f(y; 0) (0+1)0y-¹ (1-y) = 0
Answers
The offered question seems to use a probability density function, yet the accompanying equation appears to have a mistake or missing information.
Because it does not describe a suitable distribution, the equation "f(y; 0) (0+1)0y-1 (1-y) = 0" is not a legitimate probability density function.It would be good to have the accurate and comprehensive equation for the probability density function or any more information about the issue in order to give a relevant response and properly answer the question. In order for me to help you appropriately, kindly offer the right equation or any further information.

The lengths of the rectangle are each (x+4) feet. The widths of the rectangle are each "x" feet. Which expression represents the perimeter of the rectangle?
Answers
4x + 8 feet, expression represents the perimeter of the rectangle.
Describe Perimeter of Rectangle?The perimeter of a rectangle is the total distance around the outer edge of the rectangle. It is calculated by adding up the lengths of all four sides of the rectangle. In other words, it is the sum of the lengths of the four sides of the rectangle. The formula for calculating the perimeter of a rectangle is given by 2 (l + w), where l represents the length of the rectangle and w represents the width of the rectangle.
In geometry, the perimeter of a shape is a basic concept that is important in many areas of mathematics. The perimeter of a rectangle is a crucial concept in areas such as engineering, construction, and computer graphics, where accurate measurements and calculations are essential. It is also used in everyday life in applications such as landscaping, interior design, and planning home improvement projects.
The perimeter of the rectangle can be expressed as 2 * (length + width). If the length of the rectangle is (x+4) feet and the width is x feet, then the perimeter can be expressed as:
2 * ((x+4) + x) = 2 * (2x + 4) = 4x + 8 feet.
