Remark
f(x) = 9x^2 - 5x + 3 is given. The notation means that wherever you see and x on the right, you replace it with the x in the brackes on the left. f(3) is a direction, not anything you have to adjust or manipulate.
Solution
f(-3) = 9*(-3^2) - 5*(-3) + 3 (-(3))^2 = -3 * -3 = 9 two minuses make a +
f(-3) = 9*(-3)(-3) + 15 + 3 -3 times an operation of minus equals a +
f(-3) = 9 * 9 + 15 + 3
f(-3) = 81 + 15 + 3
Answer: f(-3) = 99
How many cubes with side length of 4cm can be packed into a wooden box measuring 32cm by 16cm by 8cm
PLEASE HELP Me!!
Answer:
64 cubes
Step-by-step explanation:
The volume of wooden box,
→ x = l × b × h
→ x = 32 × 16 × 8
→ [x = 4096 cm³]
The volume of a cube,
→ y = side³
→ y = 4 × 4 × 4
→ [ y = 64 cm³]
Now we have to,
find how many cubes can be packed inside the wooden box.
→ x ÷ y
→ 4096 ÷ 64
→ 64 cubes
Hence, the solution is 64 cubes.

Let f(t) ANSWER: 1+ = t² - 1 t+3 Find f'(1)
Answer:
f(1) = 3
Step-by-step explanation:
f(t) = t² - 1t + 3
we want to find f(1)
all we have to do is replace the t's with 1 and evaluate
f(1) = (1)² - 1(1) + 3
evaluate exponent 1² = 1
f(1) = 1 - 1(1) + 3
multiply
f(1) = 1 - 1 + 3
subtract
f(1) = 3

Answer: -1 [tex]\frac{1}{5}[/tex], -1, 0.25, [tex]\frac{1}{2}[/tex] , 0.75
Step-by-step explanation:
I will turn all of these numbers into numbers that are not fractions since most of the numbers are already this way.
0.75 -> 0.75
-1 -> -1
[tex]\frac{1}{2}[/tex] -> 0.5
-1 [tex]\frac{1}{5}[/tex] -> -1.2
0.25 -> 0.25
First of all, the negative numbers are smaller than the positive numbers. Then, we can order them least to greatest by number.
-1.2, -1, 0.25, 0.5, 0.75
Putting the numbers into what they were originally given as gives us this:
-1 [tex]\frac{1}{5}[/tex], -1, 0.25, [tex]\frac{1}{2}[/tex] , 0.75
The answer is the last option, -1 [tex]\frac{1}{5}[/tex], -1, 0.25, [tex]\frac{1}{2}[/tex] , 0.75.
if z 2 square equal 49 what are the solutions
z = 7, z = -7
Calculations ↓z² = 49
Take the square root of both sides to find what z equals
z = 7
Is that the only solution? Is 7 the only number that can be multiplied by itself and have a result of 49? No, there's another number. This number is -7.
So the solutions are ↓7, -7

Below there are graphs of some inverse proportions. What function each one represent?
Answer:
y = 15/x
Step-by-step explanation:
An inverse proportion has the equation ...
y = k(1/x) . . . . k is the constant of proportionality
__
Solving for k, we find ...
k = xy
The coordinates of the given point can be used to find k:
k = (3)(5) = 15
Then the equation of the graph is ...
y = 15/x

Medical assistants are to receive a 9% increase in wages per hour. If they were making $16.75 an hour, what is the new wage per hour to the nearest cent?
A percentage is a way to describe a part of a whole. The new wage per hour to the nearest cent if it is increased by 9% will be $18.26.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the Medical assistants are to receive a 9% increase in wages per hour. While the current wage of Medical assistance is $16.75 an hour.
Therefore, the new wage per hour to the nearest cent will be,
New wage = Old wage + 9% of old wage
= $16.75 + 0.09($16.75)
= $18.26
Hence, the new wage per hour to the nearest cent will be $18.26.

Answer:
WX = 20
FG = 10
Step-by-step explanation:
If EFGHI ~ VUTXW
then:
EF~VUFG~UTGH~TXHI~XWIE~WVThe only pair of sides that both have measures is EF and VU
EF = 8
VU = 16
VU/EF = 16/8 = 2
Therefore, VUTXW is enlargement of EFGHI by a scale factor of 2.
As HI = 10
