A line has the equation 3x–4y–12=0.
Is the point (2, −1) on the graph?
Answers
Answer:
The point (2, -1 ) is not on the graph of the line.
Step-by-step explanation:
3x–4y–12=0
3*2 - 4*(-1) - 12= 0
6 + 4 - 12 =0
10 - 12 = 0
- 2 = 0 , false, so the point (2, -1 ) is not on the graph of the line.
p(s) = s³ + 10s

Find p(2)-f(2)
Answers
Answer:
19
Step-by-step explanation:
We are given the following two functions of s
\(p(s) = s^3 + 10s\\f(s) = 6s - 3\\\\\text{To find p(2) substitute 2 for s in p(s)}\\p(2) = (2)^3 + 10(2) = 8 + 20 = 28\\\\\)
\(\text{To find f(2) substitute 2 for s in f(s)}\\f(2) = 6(2) - 3= 12 - 3= 9\\\)
\(p(2) - f(2) = 28 - 9 = 19\)

Angle CCC is inscribed in the circle OOO.

AB
start overline, A, B, end overline is a diameter of circle OOO.
What is the radius of the circle OOO?
_______________ units
Answers
The radius of the circle shown in the diagram is: 5 units.
What is the Radius of a Circle?The radius of a circle is half of the length of the diameter of any given circle. Which means, the diameter is as twice as long as the radius of a circle.
Based on the inscribed angle theorem, the measure of the inscribed angle ACB is equal to a right angle, since: m<ACB = 1/2(measure of arc AB).
Arc AB = half a circle which is 180 degrees. Therefore: m<ACB = 1/2(180).
m<ACB = 90°.
This means that triangle ACB is a right angle. To find the length of the diameter of the circle, which is the length of segment AB, apply the Pythagorean theorem:
AB = √(AC² + BC²) [Pythagorean theorem]
Substitute
AB = √(6² + 8²)
AB = √(36 + 64)
AB = √100
AB = 10 units
Therefore:
Radius of the circle = 1/2(10)

How many different types of labels will the manufacturers have to produce?
Answers
Answer: The total number of different types of labels will the manufacturers have to produce = 24.

Given: Choices for flavours = 4
Choices for sugar = 2 {either sugar or sugar free}
Choices for the qunatity = 3
By Fundamental counting principle,
Total number of different types of labels will have to produce = (Choices for flavors) x (Choices for sugar)x (Choices for the quantity )

The second pair of points representing the solution set of the system of equations is (-6, 29).
To find the second pair of points representing the solution set of the system of equations, we need to substitute the x-coordinate of the second point into one of the equations and solve for y.
Given the system of equations:
y = x^2 - 2x - 19
y + 4x = 5
Substituting the x-coordinate of the second point (-6) into equation 2:
y + 4(-6) = 5
y - 24 = 5
y = 5 + 24
y = 29

what is the midpoint of 70 and 90
Answers
Answer:
80
Step-by-step explanation:
Just average the two numbers to get (70+90)/2 = 160/2 = 80
Answer:
Step-by-step explanation:
To find the midpoint between two numbers, you add them together and divide the sum by 2.
In this case, the midpoint between 70 and 90 would be:
(70 + 90) / 2 = 160 / 2 = 80.
Therefore, the midpoint between 70 and 90 is 80.
Points A and B are on opposite sides of a lake. Another point, C. is 94.4 meters from Angle A. The measure of Angle A is 72° and the measure of Angle C is 30°. Find the distance between A and B.
Answers
To find the distance between points A and B, we can use trigonometry and the given information.
Let's label the distance between A and B as "d". We know that point C is 94.4 meters away from point A. From angle A, we have the measure of 72°, and from angle C, we have the measure of 30°.
Using trigonometry, we can use the tangent function to find the value of "d".
tan(72°) = d / 94.4
To solve for "d", we can rearrange the equation:
d = tan(72°) * 94.4
Using a calculator, we can evaluate the expression:
d ≈ 4.345 * 94.4
d ≈ 408.932
Therefore, the distance between points A and B is approximately 408.932 meters.
Suppose you have $6,000 in savings when the price level index is at 100.
a. What is the real value of your savings if the price level increases by 10 percent for the year?
b. What is the real value of your savings if the price level declines by 5 percent for the year?
Answers
Answer:
a. The real value of your savings is $5,454.55.
b. The real value of your savings is $6,315.79.
Step-by-step explanation:
The real value of savings can be calculated using the following formula:
Real value of savings value = Savings amount / (Current price index / Previous price index) ..................... (1)
Therefore, we have:
a. What is the real value of your savings if the price level increases by 10 percent for the year?
Savings amount = $6,000
Previous price index = 100
Current price index = Previous price index + Percentage increase in the price level = 100 + 10 = 110
Substituting all the relevant values into equation (1), we have:
Real value of savings = $6,000 / (110 / 100) = $5,454.55
Therefore, the real value of your savings is $5,454.55.
b. What is the real value of your savings if the price level declines by 5 percent for the year?
Savings amount = $6,000
Previous price index = 100
Current price index = Previous price index - Percentage decrease in the price level = 100 - 5 = 95
Substituting all the relevant values into equation (1), we have:
Real value of savings = $6,000 / (95 / 100) = $6,315.79
Therefore, the real value of your savings is $6,315.79.

Two increased by the product of a number and 7 is at most -29
Answers
The number that satisfies the equation is x = -31/7. This means that if we increase two by the product of a number and 7, the result is at most -29 if the number is -31/7.
The expression we need to solve is "Two increased by the product of a number and 7 is at most -29". We can express this as 2 + x × 7 ≤ -29 where x is the number we need to find.In order to solve this equation, we need to start by isolating the variable x. We can subtract 2 from both sides of the equation to get x × 7 ≤ -31. Then, we divide both sides of the equation by 7 to get x ≤ -31/7.Therefore, the number that satisfies the equation is x = -31/7. This means that if we increase two by the product of a number and 7, the result is at most -29 if the number is -31/7.

Juliet has a choice between receiving a monthly salary of $1900 from a company or a base salary of $1800 and a 5% commission on the amount of furniture she sells during the month. For what amount of sales will the two choices be equal?
Answers
Juliet will earn the same amount of money whether she chooses a monthly salary of $1900 from the company or a base salary of $1800 plus a 5% commission on furniture sales if her sales amount to $2000.
To find the amount of sales for which the two salary choices are equal, we set the equation for the base salary plus commission equal to the equation for the flat monthly salary. The equation can be written as:
1800 + 0.05x = 1900
where x is the amount of furniture sales in dollars.
Simplifying and solving for x, we get:
0.05x = 100
x = 2000
If she sells less than $2000 of furniture, she will earn more with the flat monthly salary of $1900. If she sells more than $2000 of furniture, she will earn more with the base salary plus commission. This calculation provides an important decision-making tool for Juliet, as she can tailor her salary choice based on her expected sales for the month.

The probability that you select a card that is NOT a Club given that is it NOT a Jack is 38/47
The probability that you select a Jack given that it is a Club P(Jack|Club):
There are 4 Jacks in a deck (one for each suit), and since we are given that the selected card is a Club, we only need to consider the 13 cards in the Club suit.
So, the number of favorable outcomes is 1 (the Jack of Clubs), and the total number of possible outcomes is 13 (the number of cards in the Club suit)
P(Jack|Club) = 1 / 13
The probability that you select a Club given that it is a Jack
P(Club|Jack):
P(Club|Jack) = Number of favorable outcomes / Total number of possible outcomes
P(Club|Jack) = 1 / 4
The probability that you select a card that is not a Jack given that it is not a Club
P(NotJack|NotClub):
The number of cards that are not Jacks is 52 - 4 = 48 (since there are 4 Jacks in the deck), and the number of cards that are not Clubs is 52 - 13 = 39 (since there are 13 cards in the Club suit).
P(NotJack|NotClub) = Number of favorable outcomes / Total number of possible outcomes
P(NotJack|NotClub) = (48 - 1) / (39 - 1)
