Answer: well according 2 me the answer here is 135
Step-by-step explanation:
but unfortunately you don't have it in your choices
Answer:
B
Step-by-step explanation:
Converting it to z, we can use the formula of z-score:
z-score = 
Where
x is the value we are checking for (here, x = 79)
is the mean, which is 85
is the standard deviation, which is 4 now
<em>Let's plug the information into the formula and solve for the answer:</em>

<em>B is the correct answer.</em>
Answer:
Given the radical form: 
Use the exponent rules:
![\sqrt[n]{a^m} = (a^m)^{\frac{1}{n}} = a^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5Em%7D%20%3D%20%28a%5Em%29%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%20%3D%20a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)
we can write 
as:
then;
= 
Therefore, in exponential form is
11 in - 7 in = 4 in
a^2 + (4 in)^2 = (5 in)^2
a^2 + 16 in = 25 in
a^2 = 9 in
a = 3 in
7 in x 3 in = 21 in
1/2( 3 in ) ( 4 in ) = 6 in
a = 21 in + 6 in = 27 in
To answer "which function has the smallest minimum," we'll first find the minimum of each one separately.
[1] f(x) = -3 sin(x - pi) + 2. No matter how crazy the inside of a sin function looks, the value of sin itself is always between 1 and -1. So, the minimum value for f(x) is -3*1 + 2 = -1.
[2] g(x). By looking at the table, we see that the minimum value is -1, which occurs when x = 3.
[3] h(x) = (x+7)^2 - 1. Notice that (x+7) is being squared, so the smallest that piece could be is 0 (you can never get a negative number out of (x+7)^2...). So, the minimum value of h(x) is 0 - 1 = -1.
At the end of the day, all three functions have the same minimum value! This can be confirmed on a graph. So, "which function has the smallest minimum value?" all of them!
