Answer:
A. 9x^4 and 3x^5y
Step-by-step explanation:
there are two ways to solve this:
first way:
You can solve this my substituting numbers for x and y in this case i used 2 for x and 3 for y and see which one is equal to the original equations
the second way is the regular way
when you add or subtract numbers with variables and exponents you want to add the constants and add the exponents in this case [tex]5x^{4} +4x^2[/tex] is the same as [tex](5x+4x)^(4+4)[/tex] = [tex]9x^4[/tex]and you can do the same process for subtraction
[tex]12x^{5}y-9x^5 y\\(12x-9x)^(5+5)*y[/tex]= [tex]3x^5y[/tex]

Find the surface area of a sphere with a radius of 2√2 feet.
94.5 square feet
100.5 square feet
25.1 square feet
35.5 square feet
Answers
Answer: 100.5 square feet
Step-by-step explanation:
To find : surface area of sphere with radius of [tex]2\sqrt{2}feet[/tex]
The formula used to calculate surface area of sphere is = [tex]4\times \pi\times r^2[/tex]
where r is the radius of sphere.
Putting the values we get:
surface area of sphere = [tex]4\times 3.14\times (2\sqrt{2}feet)^2=100.5square feet[/tex]
Thus the surface area of a sphere with a radius of 2√2 feet is 100.5 square feet

A group of friends were working on a student film. They spent all their budget on props and equipment. They spent $693 on props, and 37% of the total budget on equipment. What was the total budget for their student film?
Answers
Answer:
$1100
Step-by-step explanation:
Let the total budget = b
amount spent on props + amount spent on equipment = total budget
If 37% of the budget was spent on equipment
The percentage spent on props = 100% - 37% = 63%
63% of the total budget is $693
the above sentence presented as an equation gives :
63/100 x b = 693
to find b, divide both sides of the equation by 100/63
b = $1100
Answer:
1100

What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
From the equation, the two points of Dave's line will be (0, 6) and (2, 9). Then the equation is given as,
(y - 6)[(9 - 6) / (2 - 0)](x - 0)
y = 1.5x + 6
From the equation, the two points of Andrew's line will be (0, 3) and (1, 5). Then the equation is given as,
(y - 3) = [(5 - 3) / (1 - 0)](x - 0)
y = 2x + 3
The number of hours when the amount Andrew and dave pay for the rentals be equal will be calculated as,
2x + 3 = 1.5x + 6
0.5x = 3
x = 6 hours
The number of hours when the sum Andrew and dave pay for the rentals be equivalent will be 6 hours.

Answer:
x-intercept (s):
For this case h (x) = 0
x2 - 2x - 8 = 0
(x-4) * (x + 2) = 0
x1 = 4
x2 = -2
y-intercept:
For this case x = 0
h (0) = (0)2 - 2 (0) - 8
h (0) = - 8
vertex:
We derive the equation:
h '(x) = x2 - 2x - 8
h (x) = 2x - 2
We match zero:
2x-2 = 0
x = 2/2
x = 1
We evaluate the function for x = 1
h (1) = (1)2 - 2 (1) - 8
h (1) = 1 - 2 - 8
h (1) = -9
The vertex is:
(1, -9)
