If u were to graph that function used u would have to solve it first
Answer:
C: x≥12
D: x<-15
E: x<7.5 or 15/2
F: x<-8
G: x≥-2.7 or -8/3
H: x≥-6
Step-by-step explanation:
I trust you know how to graph it
<span>Answer:
We'll have to integrate the growth rate with respect to time, without forgetting the amount of area covered at the start.
A = 2010 + â« 8t1/2 dt (as t goes from 0 to 24)
A = 2010 + [(16/3) t3/2] (as t goes from 0 to 24)
A = 2010 + 627 = 2637 acres
We don't integrate the 2010 here because whatever effects of the passing of time have already taken place over that area. We just treat it as a constant and add it to the result of integration.</span>
Answer:
Property of equality division
Step-by-step explanation:
Given
c = d
b ≠ 0 then c∕b = d∕b
Required
State the property used
From list of options a through d, only option A best fits the description.
This is so because property of equality division is such that
given two variables c and d where c = d
Provided that b ≠ 0
Take for instance;
b = 2; c = 8 and d = 8;
This implies that
Divide both sides by 2 (assumed value of b)
We have the following equation:
h (t) = - 16t ^ 2 + 161t + 128
We substitute the value of h (t) = 170:
170 = -16t ^ 2 + 161t + 128
We rewrite the equation:
-16t ^ 2 + 161t + 128 - 170 = 0
-16t ^ 2 + 161t - 42 = 0
We look for the roots of the equation:
t1 = (161/32) + root (23233) / 32
t2 = (161/32) - root (23233) / 32
Answer:
The object is 170 feet off the ground at the following times:
t1 = (161/32) + root (23233) / 32
t2 = (161/32) - root (23233) / 32
