The function D(t) defines a traveler’s distance from home, in miles, as a function of time, in hours. Which times and distances are represented by the function? Select three options. The starting distance, at 0 hours, is 300 miles. At 2 hours, the traveler is 725 miles from home. At 2.5 hours, the traveler is still moving farther from home. At 3 hours, the distance is constant, at 875 miles. The total distance from home after 6 hours is 1,062.5 miles.
Answer:
B, D, E
Step-by-step explanation:
The times and distances that represents the travelers motion are;
At 2 hours, the traveler is 725 miles from home.At 2.5 hours, the traveler is still moving farther from home.At 3 hours, the distance is constant, at 875 miles.The total distance from home after 6 hours is 1,062.5 miles.The given parameters;
[tex]D(t) = 300t \ + \ 125, \ \ \ \ \ 0\leq t\leq 2.5\\\\D(t) = 875, \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2.5 \leq t\leq 3.5 \\\\D(t) = 75t + 612.5 , \ \ \ \ \ \ 3.5 \leq t\leq 6 \\\\[/tex]
From the given distance function, we can calculate the distance traveled at each time;
at 0 hours, the starting distance of the traveler is calculated as;
[tex]D = 300(0) + 125\\\\D = 125 \ miles[/tex]
at 2 hours, the distance traveled is calculated as;
[tex]D = 300(2) + 125\\\\D = 725 \ miles[/tex]
at 2.5 hours, the distance traveled by the traveler is calculated as;
[tex]D = 300(2.5) + 125\\\\D = 875 \ miles[/tex]
At 3 hours, the distance traveled by the traveler is calculated as;
[tex]D(t ) = 875 \ \ \ \ \ 2.5 \leq t \leq 3.5\\\\D(3) = 875 \ miles[/tex]
The total distance from home after 6 hours is calculated as follows;
[tex]D = 75(6) \ + \ 612.5\\\\D = 1,062.5 \ miles[/tex]
Thus, the times and distances that represents the travelers motion are;
At 2 hours, the traveler is 725 miles from home.At 2.5 hours, the traveler is still moving farther from home.At 3 hours, the distance is constant, at 875 miles.The total distance from home after 6 hours is 1,062.5 miles.Learn more about time and distance here: https://brainly.com/question/2854969
Marsha initially deposited $98,232 into her checking account in January. She deposited $14,443 into her account at the beginning of every month starting in February. About how much money will she have at the end of April?
First we have to subtract 14,443 from 98,232 since deposit means take out. Now that would become 83,789 so that would continue from Feb to April that would be about 3 times so we have to keep subtracting 14,443 or just do 14,442 since we have to do this 3 times and then subtract 98,232 from 43326(the answer from 14,442*3) and we get 54906 as our final answer!

Step-by-step explanation:
solution
here,
4x+c=w
or, 4x=w-c
:.x=w- c/x
As x subject, the linear equation is x = 1/4(w -c).
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
We have a linear equation,
4x+c=w.
To make x a subject:
4x = w - c
x = 1/4(w -c)

A Ferris wheel 80 meters in diameter turns continuously, completing a single rotation once every 8 minutes. You must board the Ferris wheel at its lowest point from a platform located 5 meters above the ground. If you board the Ferris wheel at t=0, write and sketch a sinusoidal function to model your height above the ground after t minutes on the Ferris wheel. How high above the ground will you be after 5 minutes? How many minutes into the ride will it be when you first reach 35 meters above the ground?
Step-by-step explanation:
General form of a sine or cosine wave is:
y = ±A sin((2π/T) t) + B
y = ±A cos((2π/T) t) + B
where A is the amplitude, T is the period, and B is the vertical offset or midline.
The Ferris wheel is 80 meters in diameter or 40 meters in radius.
A = 40
The Ferris wheel turns once every 8 minutes.
T = 8
The lowest point is 5 meters above the ground, so the center of the Ferris wheel is 45 meters above the ground.
B = 45
At t=0, you're at the lowest point, so use -cos.
Therefore, the equation is:
y = -40 cos(2π/8 t) + 45
y = -40 cos(π/4 t) + 45
When t = 5:
y = -40 cos(5π/4) + 45
y = 20√2 + 45
y ≈ 73.3 meters
When y = 35:
35 = -40 cos(π/4 t) + 45
-10 = -40 cos(π/4 t)
1/4 = cos(π/4 t)
π/4 t ≈ 1.318
t ≈ 1.68 minutes

A photographer charges a sitting fee of $15 plus $3 for each pose. Write a function to describe the situation. Find a reasonable domain and range for up to 5 poses.
Please help i really don't understand how to find the domain and range.
Answer:y=3x+15
Step-by-step explanation: (1,18), (2,21), (3,24), (4,27), (5,30) domain is your x values 1,2,3,4,5. Range is your y values. I’d assume someone wouldn’t pay $15 for 0 poses.
The function for the given situation is f(x)=15+3x and a reasonable domain and range for up to 5 poses is 5 and 30 respectively.
Given that, a photographer charges a sitting fee of $15 plus $3 for each pose.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Let the number of poses be x and the total cost be y.
The function for the given situation is y=15+3x
Thus, f(x)=15+3x
For 5 poses:
Put x=5 in the obtained function, we get
f(5)=15+3(5)
= 15+15
= 30
So, the ordered pair is (5, 30)
Hence, the function for the given situation is f(x)=15+3x and a reasonable domain and range for up to 5 poses is 5 and 30 respectively.

Answer:
Angle 1: 131
Angle 6: 49
Answer:
m∠1 = 131º
m∠6 = 49º
Step-by-step explanation:
So we know that a straight line is equal to 180º and we already know the measure of angle 8 (49º) so to find the measure of angle 7, we just subtract 49 from 180.
180 - 49 = 131
So m∠7 = 131º
Now because of the alternate exterior angle rule, we can now find out that m∠7 is the same as m∠1
Now for the measurement of angle 6, we know that it's 49º because of the vertical angles rule.

whats the surface area of this shape?
Answer:
168 square units
Step-by-step explanation:
From left to right, top to bottom
1. 5 x 10 = 50
2. 5 x 8 = 40
3. 5 x 6 = 30
For the triangles since there is 2 of them and there the same we play it like there is 1 square
4 & 5. 8 x 6 = 48
Now add all them
50 + 40 + 30 + 48
50 + 40 = 90
30 + 48 = 78
90 + 78 = 168
Answer:
168 square units
Step-by-step explanation:
5*10 = 50 (left rectangle)
8*6 = 48 (top and bottom triangles, not dividing by 2 as there is two of that exact shape)
5*8 = 40 (middle rectangle)
6*5 = 30 (right rectangle)
Add them all up
50+48+40+30 = 168.

You walk 2/5 miles to a clothing store. Then you walk another 1/2 miles to a music store. How many miles have you walked in all?
Answer:
9/10ths of a mile. Or 0.9 miles.
Step-by-step explanation:
To get the total it's helpful to look at it in decimals:
2/5 mile = 0.4 miles (1 mile divided by 5 = 0.2 miles, times that by 2)
1/2 mile = 0.5 miles
Add them together = 0.9 miles.
Which is 9/10ths of a mile.
The total distance walked will be equal to [tex]\frac{9}{10}[/tex] miles or 0.9 miles.
It is given that you walk 2/5 miles to a clothing store and then walk another 1/2 miles to a music store.
We have to find out the total distance in miles that you have walked.
What do you mean by fractions ?
A fraction can be defined as a portion or part of any quantity or it defines a part of a whole.
As per the question ;
You walk 2/5 miles to a clothing store
and
then ; walk another 1/2 miles to a music store.
To find out the total distance walked by you in total , we need to add both the distances given in the question.
i.e.,
Total distance will be ;
= [tex]\frac{2}{5}[/tex] + [tex]\frac{1}{2}[/tex]
= [tex]\frac{4+5}{10}[/tex]
= [tex]\frac{9}{10}[/tex] miles
or
= 0.9 miles
Thus , the total distance walked will be equal to [tex]\frac{9}{10}[/tex] miles or 0.9 miles.
