Stephen is merging onto a highway. The increase in Stephen's speed for the first 8 seconds can be described by the function f(t)=t2+13t, where t is time in seconds. Which is the average rate of change of f(t) between t=2 and t=6?
Answers
Answer:
21m/s
Step-by-step explanation:
The average rate of change is expressed as;
A(t) = f(b) - f(a)/b-a
a = 2, b = 6
f(2) = 2² + 13(2)
f(2) = 4 + 26
f(2) = 30
f(6) = 6² + 13(6)
f(6) = 36 + 78
f(6)= 114
b- a = 6-2
b-a = 4
Substitute;
A(t) = 114 - 30/4
A(t) = 84/4
A(t) = 21
Hence the average rateof change is 21m/s

8. A cellphone company charges $29.99 per month for the first 500 minutes of calls and $0.30 a minute for any calls over the 500-minute limit. . Last month Demetria made 615 minutes of calls on her cellphone. Excluding tax, what were the total charges for her cellphone calls last month? A. $29.99 B. $34.50 C. $64.49 D. $184.50
Answers
Answer:
C) $64.49
Step-by-step explanation:
let 'x' = #minutes
cost = 29.99 + 0.3(x-500)
= 29.99 + .3(115)
= 29.99 + 34.50
= $64.49

what is the area of triangle EDF?
Answers
Answer:
4.5
Step-by-step explanation:
∠BAC ~ ∠EDF means that the triangles are similar. So the legs of the triangle share the same proportions, even if the sizes are different.
Since they share the same proportions, the same operations can be performed on each base to find the area.
The answer can be found with the knowledge that the area of a triangle is half of the height * width. You know the width of ∠BAC is 4, and the area is 8, so 16 (the area doubled) / 4 is the height. The width and height of ∠BAC are the same, and since the proportions are also the same, the width and height of ∠EDF are both 3. So the area is the width (3) times the height (3) divided by 2.
3*3 = 9
9/2 = 4.5
So the area is 4.5

How would someone Algebraically determine X-Y intercepts?
Answers
Answer:
y-int: -6
x-int: -2/5 and 3
Step-by-step explanation:
you can find the y-intercept by substituting zero in for every 'x' in the equation;
y = 5(0) - 13(0) - 6
y = -6
to find the x-intercept(s), factor the trinomial by trying to find a pair of factors that multiply to 6 and add to -13; the factors that work are:
(5x + 2)(x - 3)
now set each factor equal to zero and solve for 'x':
5x + 2 = 0
5x = -2
x = -2/5
x - 3 = 0
x = 3

The value of x is 35 degrees, as it is opposite to the other 35 degree angle. Now, to find y. We can see by the indicators that the measure of the y angles are equal. These angles, along with the 35 degree angle that is indicated are in a straight angle. This helps us. Form an equation.
2y+35=180
2y+35-35=180-35
2y=145
y=72.5
Therefore, the value of the x angle is 35 degrees and the value of the y angle is 72.5 degrees.

Find the input (x) of the function y = 1/4x+ 12 if the output
(y) is 6
Answers
Answer:
x = -24
Step-by-step explanation:
y = 1/4x+12 (Substitute 6 for y)
6 = 1/4x+12 (Subtract 12 from both sides)
6-12= -6 so its now -6 = 1/4x and since its a fraction you want to multiply both sides by the reciprocal
4*-6 = 1/4x*4 (1/4*4=1 which is 1x or x)
-24 = x
Answer:
y=1/4x+12
6=1/4x+12
1/4x=6-12
1/4x=-6
0.25x=-6
x=-6÷0.25
x=-24

Step-by-step explanation:
perimeter= AB + BC + CE + DE + AD
AB= DE = 7
BC = 5
EC= 3
DE = 7
AD = 4
So, perimeter = 7+ 5+ 3+ 7+ 4
→ 12+ 10 +4
→ 24+ 4
→26
So, 26 is your answer
