To find an equation for a line perpendicular to y = 3z + 1 and passing through the point (9, 1), we can determine the slope of the given line and then find the negative reciprocal to obtain the slope of the perpendicular line.

The equation y = 3z + 1 represents a line with a slope of 3. The slope of a line perpendicular to this line would be the negative reciprocal of 3, which is -1/3. Therefore, the perpendicular line will have a slope of -1/3.

Next, using the point-slope form of a line, we substitute the slope (-1/3) and the given point (9, 1) to obtain the equation of the perpendicular line. The point-slope form is given as:

y - y₁ = m(x - x₁),

where (x₁, y₁) represents the given point and m represents the slope.

Substituting the values, we have:

y - 1 = (-1/3)(x - 9).

Simplifying further, we distribute -1/3 to the terms inside the parentheses:

y - 1 = (-1/3)x + 3.

Finally, we can rearrange the equation to obtain the standard form:

(1/3)x + y = 4.

Therefore, an equation for the line perpendicular to y = 3z + 1 and passing through the point (9, 1) is (1/3)x + y = 4.

Answer:

90

Step-by-step explanation:

let the number to be found be x then

23 \(\frac{1}{3}\) % of x = 21  ( change mixed number to improper fraction )

\(\frac{\frac{70}{3} }{100}\) x = 21

\(\frac{70}{300}\) x = 21 ( multiply both sides by 300 to clear the fraction )

70x = 6300 ( divide both sides by 70 )

x = 90

Then 23 \(\frac{1}{3}\) % 0f 90 = 21

This situation follows the next exponential decay formula:

where

• a is the initial hairs

• r is the losing rate (as a decimal)

• t is time in years

• y is the remaining hairs

Replacing with a = 1889, r = -0.26 (notice the negative sign) and t = 8, we get:

He will have left about 170 hairs after 8 years

The identified parameters are:

ta = 6 minutes

tθ = 11 minutes

∂a = 4 minutes

∂θ = 20 minutes

ra = 1/6 minutes^(-1)

rθ = 1/11 minutes^(-1)

ta: Mean time between calls to the center

tθ: Effective response time

∂a: Standard deviation of the time between calls to the center

∂θ: Standard deviation of the effective response time

ra: Rate of calls to the center (inverse of ta, i.e., ra = 1/ta)

rθ: Rate of effective response (inverse of tθ, i.e., rθ = 1/tθ)

Given information:

Mean time between calls to the center (ta) = 6 minutes

Standard deviation of time between calls (∂a) = 4 minutes

Effective response time (tθ) = 11 minutes

Standard deviation of effective response time (∂θ) = 20 minutes

Using this information, we can determine the values of the parameters:

ta = 6 minutes

tθ = 11 minutes

∂a = 4 minutes

∂θ = 20 minutes

ra = 1/ta = 1/6 minutes^(-1)

rθ = 1/tθ = 1/11 minutes^(-1)

So, the identified parameters are:

ta = 6 minutes

tθ = 11 minutes

∂a = 4 minutes

∂θ = 20 minutes

ra = 1/6 minutes^(-1)

rθ = 1/11 minutes^(-1)

Population of Wisconsin is 9.3 × 10⁰ times greater than the population of Vermont.

As given in the question,

Population of Wisconsin is equal to  5.82 × 10⁶

Population of Vermont is equal to  6.24 × 10⁵

Let 'x' represents the number of times population of Wisconsin is greater than the Vermont

⇒ x = ( population of Wisconsin ) / (Population of Vermont)

⇒ x = ( 5.82 × 10⁶ ) / ( 6.24 × 10⁵ )

⇒ x = 0.933 × 10⁶⁻⁵

⇒ x = 0.933 × 10¹

⇒ x = 9.3 × 10⁰ ( Standard notation , rounding to nearest tenth)

Therefore, population of Wisconsin is 9.3 × 10⁰ times greater than the population of Vermont as per given data.

Gus jas driven 5 miles

Step-by-step explanation:

Emma did 30 miles of u were wondering

The time it will take both the boat and whale to meet is 18minutes(nearest minutes)

Displacement is defined as the change in position of an object in a specified direction. It is measured in meters and it's a vector quantity.

Since velocity = displacement/time

displacement = velocity ×time

The total space between the boat and the whale is 5miles.

Using addition of vectors

5= v2t - v1t

5= 46t - 30t

5 = 16t

t= 5/16 = 0.3hrs

to minutes, = 0.3 ×60 = 18minutes(nearest minutes)

Therefore it will take the boat and the whale 18minutes to meet.

and solve

The result in Exercise 7.46 can be used to slightly weaken the hypothesis in part (a) by allowing h(x) and k(x) to have continuous derivatives on the interval (a, b] instead of [a, b]. This means that the functions only need to be differentiable on the open interval (a, b), but they still need to be continuous at the endpoints a and b.

Integration by parts is a technique used to evaluate certain types of integrals by rewriting them in a different form. It is based on the product rule of differentiation. The formula for integration by parts is:
∫ h(x)k'(x)dx = h(x)k(x) - ∫ h'(x)k(x)dx
In this formula, h(x) and k(x) are two functions with continuous derivatives on the interval [a, b]. To derive this formula, we start with the product rule of differentiation:
(d/dx) [h(x)k(x)] = h'(x)k(x) + h(x)k'(x)
Now, we integrate both sides of this equation with respect to x:
∫ (d/dx) [h(x)k(x)] dx = ∫ h'(x)k(x) dx + ∫ h(x)k'(x) dx
Using the fundamental theorem of calculus, the left-hand side simplifies to:
h(b)k(b) - h(a)k(a)
Therefore, we have
∫ h'(x)k(x) dx = h(b)k(b) - h(a)k(a) - ∫ h(x)k'(x) dx
This is the formula for integration by parts. It allows us to evaluate integrals of the form ∫ h(x)k'(x) dx by relating them to integrals of the form ∫ h'(x)k(x) dx, which might be easier to compute.

Answer:

I guess that the shaded area is a quarter of a circle of radius 12 units.

Is easy to know that the area, will be equal to the quotient between the area of a circle of radius 12, and 4

We know that the area of a circle of radius R is:

A = pi*R^2

in this case, R = 12

pi = 3.14

Then:

A = 3.14*12^2 = 452.16

And a fourth of that is:

A/4 = (452.16)/4 = 113.04

~Set both factors to equal zero

x + 7 = 0

x + 5 = 0

~Solve for x in [ x + 7 = 0 ]

x + 7 = 0

x + 7 - 7 = 0 - 7

x = -7

~Solve for x in [ x + 5 = 0 ]

x + 5 = 0

x + 5 - 5 = 0 - 5

x = -5

It takes 3.6 hours for Emily and her apprentice to build a wall together and Emily completes 1/6 of the job in one hour.

As Emily can build a wall in 6 hours and her apprentice can do the job in 9 hours; therefore

Emily = 1/6 of the job per hour and,

Her apprentice = 1/9 of the job per hour

Now we can calculate the time it takes them to build a wall together by adding the fractions as follows;

1 / 6 + 1 / 9 = 3 / 18 + 2 / 18 = 3+2 / 18 = 5 / 18 of the job per hour;

Therefore the time to build a wall is calculated as follows;

5 / 18 of the job per hour = 18 / 5 hours to complete the job

18 / 5 = 3.6 hours

Hence it took them 3.6 hours to build a wall together.

The probability that the flight would be delayed when it is not raining is 12.46%.

Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event. Probability measures the chance of an event happening and is equal to the number of favorable events divided by the total number of events. The value of probability ranges between 0 and 1, where 0 denotes uncertainty and 1 denotes certainty.

To determine what is the probability that the flight would be delayed when it is not raining, the following calculation must be performed:

Probability that it will not rain = 1 - probability that it will rain

X = 1 - 0.11

X = 0.89

Probability that the flight would be delayed when it is not raining = probability that it is not raining x probability that the flight will be delayed

X = 0.89 x 0.14

X = 0.1246

0.1246 x 100 = 12.46

Therefore, the probability that the flight would be delayed when it is not raining is 12.46%.
