p³r² - (m + np)
m = -32
n = 2
p = -8
r = 4
(i assume the 3 and 2 are supposed to be squared and cubed symbols)
substitution:
-8³ · 4² - (-32 +2 · -8)
-512 · 16 - (-32 -16)
-8192 + 48
-8144 should be the answer if the portion in "p3r2" is meant to be squared and cubed symbols
Hope this helped! :D
The value of the expression p³r² − (m + np) is -8144 after plugging the values of m=−32, n=2, p=−8, and r=4.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression is:
= p³r² − (m + np)
Plug m = -32, n = 2, p = -8, and r = 4 in the expression:
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
= (-8)³(4)² − (-32 + 2(-8))
= -8192 + 48
= -8144
Thus, the value of the expression p³r² − (m + np) is -8144 after plugging the values of m=−32 , n=2 , p=−8 , and r=4.

You now have a lot of experience working with equations that compare two quantities. For example, while working with the height of a tree, you found the
relationship y = 41+5. which compared 2 (the number of years after it was planted) with y (its height in feet). Use the equation for this tree to answer the
questions below
a. What was its starting height? How can you tell from the equation?
Answer:
If you mean y = 4x + 5, then the answer is 5 (the height would be 5 feet)

Answer:
[tex]x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]
Step-by-step explanation:
Given;
x² - 2x - 1 = 0
Solve by completing the square method;
⇒ take the constant to the right hand side of the equation.
x² - 2x = 1
⇒ take half of coefficient of x = ¹/₂ x -2 = -1
⇒ square half of coefficient of x and add it to the both sides of the equation
[tex]x^2 + (-1)^2 = 1 + (-1)^2[/tex]
[tex](x-1)^2 = 1 + 1\\\\(x-1)^2 = 2\\\\[/tex]
⇒ take the square root of both sides;
[tex]x-1 = +/- \ \ \sqrt{2} \\\\x = 1 + \sqrt{2} \ \ or \ 1- \sqrt{2}[/tex]
Therefore, option B is the right solution.

HELP ME OUT JIM! math last hw for today
Answer: Choice D) As the side length increases by 1, the area increases and then decreases by an equal factor
=============================================================
Explanation:
Choice A is ruled out because the area does change. As x changes, y changes as well. This rules out choice B as well.
Choice C is somewhat close. However, it's not entirely true since the area doesn't increase by the same amount. For instance, the jump from points (2,18) to (3,24) indicate that the jump in y value is +6. But going from (3,24) to (4,28) shows a jump of +4 in the y value. So we can rule out choice C.
This means that choice D is the final answer.

Step-by-step explanation:
When two angles are complementary they add up to 90 degrees
so for example if angle 1 is 2 angle two must equal 88 (they have to add up to 90)
When two angles are supplementary they must add up to 180 (so it's the same process as table 1 but instead of adding to 90 it's 180)
Answer:
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2
Step-by-step explanation:
complementary means they add up to 90°
m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4
supplementary means they add up to 180°

5/4(2 - k) = 2(3k - 1) - 2/3k
9514 1404 393
Answer:
k = 54/79
Step-by-step explanation:
You can eliminate fractions by multiplying both sides by 12.
15(2 -k) = 24(3k -1) -8k
30 -15k = 72k -24 -8k
54 = 79k
54/79 = k

The solution of (10 x/6)(10 x/8) = 1010 is
The solution to the exponential expression is given as follows:
x = 34.29.
How to solve the exponential expression?
The exponential expression for this problem is defined as follows:
[tex]10^{\frac{x}{6}} \times 10^{\frac{x}{8}} = 10^{10}[/tex]
When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents.
The sum of the exponents is given as follows:
x/6 + x/8 = 4x/24 + 3x/24 = 7x/24.
Hence the equivalent expression is given as follows:
[tex]10^{\frac{7x}{24}} = 10^{10}[/tex]
The function 10^x is an injective function, hence the value of x is obtained as follows:
7x/24 = 10
7x = 240
x = 240/7
x = 34.29.

This ellipse is centered at the origin. Find it’s equation. Verticles: (0,-6) (0,6) Foci: (0,-2) (0,2)
The equation of the ellipse will be x² / 36 – y² / 32 = 1.
What is an ellipse?An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.
This ellipse is centered at the origin.
Vertices: (0,-6) (0,6)
Foci: (0,-2) (0,2)
Then the equation of the ellipse will be given as
x² / a² – y² / b² = 1
Let c be the distance between the origin to foci.
Then we have
c = 2
And the value of a will be
a = 6
Then the value of a² will be
a² = 6² = 36
The value of b is the distance from center to one of the Co-vertices. Then the value of b² will be
a² – b² = c²
36 – b² = 2²
b² = 36 – 4
b² = 32
Then the equation of the ellipse will be x² / 36 – y² / 32 = 1.
