Review Question: 5) f(x) = 2xsquared + 7x - 15 find f(-8)
Answers
Answer:
f(-8) = 57
Step-by-step explanation:
When x = - 8
f(-8) = 2 x (-8)² + 7 x (-8) - 15
f(-8) = 2 x 64 - 56 - 15
f(-8) = 128 - 56 - 15
f(-8) = 128 - 71
f(-8) = 57
[tex]\sf f(x) = 2x^2 + 7x - 1[/tex]
Just substitute the value of x as (-8) .
[tex]\sf f(-8) = 2(-8)^2 + 7(-8) - 15[/tex]
[tex]\sf f(-8) = 2(64) - 7(8) - 15[/tex]
[tex]\sf f(-8) = 128 - 56 - 15[/tex]
[tex]\sf f(-8) = 128 - 71[/tex]
[tex]\sf f(-8) = 57[/tex]

Answer with step-by-step explanation:
Let's start by listing out the equation; w × l × 2l = v. If we simplify this equation, we would get w × [tex]2l^2[/tex] = v. This would mean the correct choice is B, because it shows the key equation, just written differently.

Answers
The solution of the given equation [tex](4x-16)^{1/2} = 36[/tex] is 328.
The given equation is:
[tex](4x-16)^{1/2} = 36[/tex]
What is solution of an equation?The solution of an equation is to find out the numeric value of the variable such that Left-hand side and Right-hand side becomes equal.
Squaring both sides of the given equation.
[tex][(4x-16)^{1/2} ]^2= (36)^2[/tex]
[tex]4x-16 = 36^{2}[/tex]

Jane is helping the librarian stack books on some new shelves. She is to stack 116 books on 16 shelves. The librarian told her to put the same number of books on each of the 16 shelves. Describe a different way that Jane can use to determine the number of books she should put on each shelf.
Answers
Answer: The number of books she should put on each shelf = 7
Step-by-step explanation:
Given: Total books = 116
Total shelves = 16
To determine : The number of books she should put on each shelf, we first divides the total number of books by the total shelf.
[tex]116\div 16=7\dfrac14[/tex]
So she can put 7 books in each shelf such that (7x16=) 112 books got placed and (116-112=)4 books left.
Hence, The number of books she should put on each shelf = 7.
To make a big batch of cookies for her father, Annmarie needs 1 1 4 pounds of chocolate chips, 3 4 pounds of walnuts, and 12 ounces of raisins. How many ounces of these three ingredients does she need in all?.
Answers
She will need 68 ounces in total for all three ingredients.
What will be the total ounces for all three ingredients?It is given that
For chocolate chips, she has = [tex]\dfrac{11}{4}[/tex] pounds
For walnuts, she has = [tex]\dfrac{3}{4}[/tex] pounds
For raisins, she has= 12 ounces
We know that,
[tex]\rm 1 \ pound = 16 \ ounces[/tex]
[tex]\rm For \ chocolate \ chips, she\ has = \dfrac{11}{4} \times 16 }=44 \ ounces[/tex]
[tex]\rm For \ walnuts,\ she\ has = \dfrac{3}{4} \times 16 }=12\ ounces[/tex]
[tex]\rm For\ raisins, she \ has= 12\ ounces[/tex]
so the total number of ounces she has will be the sum of all
[tex]=44+12+12 =68\ ounces[/tex]
Thus she will need 68 ounces in total for all three ingredients.
