Answer:
f(9.5) = 558.02.
Step-by-step explanation:
Because it is an exponential function, it can be written: y = (a)(b)^x
Now substitute in the two known points:
72 = (a)(b)^7.5 and
2 = (a)(b)^4 : => since 2 = (a)(b)^2 divide the left side by 2 and the right by (a)(b)^2
72/2 =[(a)(b)^7.5]/[(a)(b)^4]: => the (a) cancels out and b becomes b^(7.5–4)
36 = b^3.5: => To isolate b take the 3.5 root of both sides
{3.5 root}(36) = {3.5 root}(b^3.5)
2.783927 = b
Now to solve for a
2 = (a)(b)^4 => 2 = (a)(2.783927)^4 => 2 = (a)(60.066375) divide both sides by 60.066375 0.0332965 = a
Equation: y = (0.0332965)(2.783927)^x
Now plug in 9.5 for x
(0.0332965)(2.783927)^9.5 = 558.0178525 = 558.02
1. Equation #1: <span>g+s=150
Equation #2: </span><span>8g +5s = 900
2. Solution to the system:
</span>G = 150 – s
<span>8(150-s)+5s=900 </span>
<span>1200-8s+5s=900 </span>
<span>-900 -900 </span>
<span>300/3-3s/3
</span>
3. Idk about this one...
Answer:
E (5, 5), C (10, 4), D (10, -5). Those are the new points for each of them, since you said no files. (x, y)
Step-by-step explanation:
The line is provided for you in your file, and all you need to do is reflect the triangle from one side to the other.
A i think it could be wrong
Answer:
4
Step-by-step explanation:
8(-1)^4 - 3(-1) - 7
= 8(1)+3-7
=8+3-7
=4
