Answer:
160 feet
Step-by-step explanation:
h(t) = -16t² + 104t
h(4) = -16(4)² + 104(4)
h(4) = 160
Add 3x is the right answer
The rate of the slower cyclist is 16 mph while the rate of the faster cyclist is 21 mph.
<h3>How to calculate the rate of speed?</h3>
let us assume the following;
x = rate of slower cyclist
x + 5 = rate of faster cyclist
We know that formula for distance is;
distance = travel time*rate
Thus;
2x + 2(x + 5) = 74
Since the two cyclists are a distance of 74 miles apart after a time 2 hours. Thus;
2x + 2x + 10 = 74
4x + 10 = 74
4x = 74 - 10
4x = 64
x = 64/4
x = 16
Rate of faster cyclist = 16 + 5 = 21 mph

Answer:
for the first one its a=8
for the second one the answer is their is no solution
for the last one the answer is p = -1.
Step-by-step explanation for the last one:
1)Expand.
30-6p=16-20p
2) Subtract 16 from both sides.
30-6p-16=-20p
3 Simplify 30-6p-16 to -6p+14.
-6p+14=-20p
4 Add 6p to both sides.
14=-20p+6p
5 Simplify -20p + 6p to −14p.
14=-14p14=−14p
6 Divide both sides by−14.
-1=p
7 Switch sides.
p=-1
Length x width x height, 12 x 5 = 60, multiplied by 2 1/4 = 540. if it’s the fractions thats confusing you, to turn a fraction into a decimal you multiply the whole number by the denominator, then add the numerator.
