Answer:
Choice C
Step-by-step explanation:
f: initial value of 200 decreasing at a rate of 4%
g: initial value of 40 increasing at a rate of 8%
f is decreasing so it must go down starting at 200
That eliminates a and d
g is increasing and starts at 40 That eliminates a
We must look at b and c
g is increasing faster than f is decreasing
Choice C
The value of x that fills the coordinate are 7 or -5
<h3>Distance between two points</h3>
The formula for calculating the distance between two points is expressed as:
D = √(x2-x1)² +(y2-y1)²
Substitute the given coordinates
10 = √(15-7)² +(1-x)²
100 = 8² +(1-x)²
(1-x)² = 100 - 64
(1-x)² = 36
1- x = -6
x = 7 or -5
Hence the value of x that fills the coordinate are 7 or -5

Answer:
Speed before applying brakes = 64.8
Step-by-step explanation:
The formula is given as:
Where
s is speed of car, and
d is length of skid marks
It is given that d = 175 ft, so we substitute and find the speed of the car before the brakes were applied.
Rounding to nearest tenth, that is 64.8

b
Step-by-step explanation:
Answer:7.40 meters
Step-by-step explanation:
I went with 163 cm for the height as that is where the eyeline is and where she would be looking from. (h for hawk btw)
All you do is:
tan(30)=h/10
10*tan(30)=h
h≈5.77 meters
163cm is 1.63 meters, so add it to 5.77 and you will get 7.40
