Answer:
C. 70 pints = 35 quarts
D. 5 gallons < 21 quarts
E. 47pt < 6 gallons
Step-by-step explanation:
There is 35 quarts in 70 pints, therefore being equal to it
There are 20 quarts in 5 gallons so 21 quarts is greater
6 gallons has 48 pints so it's more than 47 pints
Answer:
The product of two rationalnumber is (-20/40 ).If one ofthe number is (4/5), then the other number is -5/8
4/5*-5/8 = -20/40
x= the number
4*x/5 =-20/40
4x*40 = -20*5
160x=-100
x=-100/160 = -5/8

f(t) = 4(t − 1)2 + 3; the minimum height of the roller coaster is 1 meter from the ground
f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground
f(t) = 4(t − 1)2 + 2; the minimum height of the roller coaster is 1 meter from the ground
Answer:
A f(1) =4(1)^2 – 8(1) +7 min height 3
Step-by-step explanation:
The function is a parabola, and the problem asks to transform the equation into f(t)=a(x-h)2 + k
Given f(t) = 4t2 -8t +7
= (4t2 - 8t + 4) + 7 - 4
=4 (t2 - 2t + 1) + 3
= 4 (t-1) 2 +3
This removes C and D from the viable choices.
Differentiating the f(t),
f’(t) = 8t – 8, the maximum/minimum value occurs at f’(t) = 0
0 = 8t – 8
t = 1
determining if maximum or minimum, f”(t) > 0 if minimum, f”(t) < 0 maximum
f”(t) = 8 > 0, therefore minimum
f(1) =4(1)^2 – 8(1) +7
= 3
Therefore, minimum height is 3.
