3937.5 should be your answer
Answer:
C. 
Step-by-step explanation:
A. the graph is a straight line with slope 1. It goes up/down infinitely far so the range is all real numbers. Not A!
B. The graph is a straight line with slope -4, so, like the function in A, the range is all real numbers. Not B!
D. The graph is an absolute value function y = |x|, reflected over the x-axis, shifted right 3 units, then shifted down 4 units. So the graph starts witha "vee" shape opening up, becomes a vee opening <u>down</u>, then ultimately gets shifted down 4 units. The range is all real numbers less than or equal to -4.
See the attached graphs. image2 is the function in answer choice D.
Answer: t = 7.85seconds
Step-by-step explanation:
Given that :
Height of tower = 986 Feets
Function s(t) = 16t^2
To find the time t 8 in Seconds taken for an object to fall to the ground from the top of the building
16t^2 = 986
t^2 = 986/16
t ^2 = 61.625
Take the square root of both sides
t = sqrt(61.625)
t = 7.85seconds
The answer to number 3 on your homework would be d
Answer:
1. 39 km/hr
2. $235
3. 16
4. 7m+3 inches
Step-by-step explanation:
1. Original speed of car: x km
x+21=60
x=39
original speed: 39 km/hr
2. Amount that the freshman class raised: x
2x+85=555
2x=555-85=470
x=235
Amount that the freshman class raised: $235
3. Number: x
5x-9=71
5x=71+9=80
x=16
The number: 16
4.
3m+5+4m-2
= 3m+4m+5-2
=7m+3 inches
