Using the equation for average rate above determine the cheetahs average rate for the entire trip
It should be noted that the cheetahs average rate for the entire trip is 55mph
How to calculate the value?The average rate for the trip is equal to the total distance traveled divided by the total time traveled.
Average Rate = 70+ 40/2= 110/2 = 55mph
Yes the average rate of the cheetah is 55 mph
The following equations represent the distance traveled on each leg of the trip.
First leg of trip: td=r1 t1= 70*t
Second leg of trip: td=r2 t2= 40*t
Write an equation for the average rate for the trip. Remember, the cheetah runs from point A to point B and back to point A.
Total distance = r1 t1+ r2 t2
Average rate = Total distance / total time
= r1 t1+ r2 t2/ t1+ t2
=70t+ 40t/ 2t
=110t/2t
= 55mph

The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.
Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.
We have:
z₁ = 7(cos(577°) + i sin(577°))
Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.
From the given information, we have:
z₂ = 21(cos(-7°) + i sin(-77°))
To find the quotient, we divide z₁ by z₂:
z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]
Substituting the given values, we have:
z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]
= (7/21) * [cos(584°) + i sin(584°)]
The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

Determine the point that is 1/3 of the distance from (-4.5, 0) to (0, 9)
The point that is 1/3rd of the distance from (-4.5,0) to (0,9) is (-3,3).We use a formula similar to the midpoint formula for finding the point.
We have been given two points (-4.5,0) and (0,9), we have to find the point is on the line formed by these two points and is 1/3rd away. We don't need to find the distance between these two points to find the asked point. We have to use a formula that is similar to finding the midpoint of a line. For two points (a,b) and (x,y) the midpoint is (\(\frac{a+x}{2} ,\frac{b+y}{2}\)).We used equal parts of the two points to find the midpoint, for 1/3rd we will be using uneven parts of the two points.
\(x_{1} =\frac{2}{3} (-4.5)+\frac{1}{3} (0)=-3\)
\(y_{1} =\frac{2}{3} (0)+\frac{1}{3} (9)=3\)
Therefore the point that lies 1/3rd of the distance from (-4.5,0) and (0,9) is (-3,3).

What is DE? Enter your answer as a decimal in the box. units The figure shows what appears to be acute triangle A B C. Point D is on side A B. Single tick marks pass through segments A D and D B. Point E is on side B C. Double tick marks pass through segments B E and E C. Segment D E is drawn. The length of side C A is 12.6.
Answer:
6.3
Step-by-step explanation:
You want the length of midsegment DE, parallel to CA, given as length 12.6.
Midsegment∆BDE ~ ∆BAC, so ...
BD/BA = DE/AC . . . . . corresponding sides are proportional
BD/(BD +DA) = BD/(BD +BD) = 1/2 = DE/12.6
Multiplying by 12.6, we get ...
DE = 12.6(1/2) = 6.3
The length of DE is half the length of CA, so is 6.3.
__
Additional comment
We cannot tell if 6 is supposed to be the answer to the question with ending statement, "The length of side CA is 12." (6 would be the correct answer in that case.) We have assumed that segment CA is 12.6, as written.
The length of a triangle midsegment is always half the length of the parallel base. (A "midsegment" joins the midpoints of the segments it intersects.)

A recent survey indicated that the mean time spent on a music streaming service is 210 minutes per week for the population of a certain country. A simulation was conducted to create a sampling distribution of the sample mean for a population with a mean of 210. The following histogram shows the results of the simulation.Which of the following would be the best reason why the simulation of the sampling distribution is not approximately normal?
The population size varies in several ways. The sample size was insufficient, which is the best explanation for why the simulation of the sampling distribution is not roughly normal.
A person's or a researcher's choice of sample size will limit the study's statistical power if it is too small or inadequate for the alpha level and the analyses they have decided to do.
Because of the aforementioned, it is much harder to determine from one's sample whether a statistical effect is existent in the population.
A sample size that is either too small or too large can affect the ability to extrapolate the results, with the latter increasing the detection of differences and accentuating statistical differences that are not clinically significant.

Answer:
a) Arithmetic,b) t(n) = 16 - 3n.-------------------------------
We observe that the sequence is decreasing with common difference of - 3.
16, 13, 10, 7, 4, 1Therefore, this is an AP, with the first term of t(1) = 13 and common difference of d = -3.
Use the nth term formula for AP:
t(n) = t(1) + (n - 1)dt(n) = 13 + (n - 1)(- 3) = 13 - 3n + 3 = 16 - 3nAnswer:
a) Arithmetic sequence
b) t(n) = 16 - 3n
Step-by-step explanation:
An Arithmetic Sequence has a constant difference between each consecutive term.
A Geometric Sequence has a constant ratio (multiplier) between each consecutive term.
Part (a)From inspection of the given table, t(n) decreases by 3 each time n increases by 1. Therefore, the sequence is arithmetic with a common difference of -3.
Part (b)\(\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}\)
Given:
a = 13d = -3aₙ = t(n)Substitute the initial value (when n = 1) and the common difference into the formula to create an equation for the nth term:
\(\implies t(n)=13+(n-1)(-3)\)

Estimate the slope of the tangent line (rate of change) to f(x) = ² at x = -1 by finding the slopes of
the secant lines through the points:
a. (-2,4) and (0,0)
secant slope, msec=
b. (-1.5, 2.25) and (-0.5, 0.25)
secant slope, msec=
a. The secant slope through (-2,4) and (0,0) is -2.
b. The secant slope through (-1.5,2.25) and (-0.5,0.25) is -2.
The estimated slope of the tangent line to f(x) = x^2 at x = -1 is approximately -2.
To estimate the slope of the tangent line to the function f(x) = x^2 at x = -1, we can find the slopes of the secant lines through different pairs of points.
a. (-2,4) and (0,0):
The coordinates of the two points are (-2, 4) and (0, 0). We can calculate the slope of the secant line passing through these points using the formula:
msec = (y2 - y1) / (x2 - x1)
Plugging in the values, we get:
msec = (0 - 4) / (0 - (-2))
= -4 / 2
= -2
So, the slope of the secant line passing through (-2, 4) and (0, 0) is -2.
b. (-1.5, 2.25) and (-0.5, 0.25):
The coordinates of the two points are (-1.5, 2.25) and (-0.5, 0.25). Using the slope formula, we can calculate the slope of the secant line passing through these points:
msec = (0.25 - 2.25) / (-0.5 - (-1.5))
= (-2) / (1)
= -2
So, the slope of the secant line passing through (-1.5, 2.25) and (-0.5, 0.25) is -2.
By finding the slopes of the secant lines, we have estimated the rate of change of the function f(x) = x^2 at x = -1. The slope of the tangent line at this point will be very close to these secant slopes, particularly as the two points used to calculate the secant lines get closer together.
