Answer:
D.
Step-by-step explanation:
Its a fifth degree function so it will have 5 roots.
One of the 3 roots is complex ( imaginary):- 4 + i so there must be another root value 4 - i because these roots always occur as conjugate pairs.
The fifth root must be real because you cant have just one imaginary root.

Answer:
the water level decreases by 5 feet per hour
Step-by-step explanation:
firstly the bar is going downwards, hence ,making a loss, decrease etc
so 1st and 3rd are out
initially we had 30ft of water
after
1 hr = 25 ft
- 5 ft decreased
2hrs = 20 ft
- 5 ft decreased again from the previous time checked
3hrs = 15 ft
- 5 ft decreased 1 hr ago
hence the water level decreases by 5 feet per hour

Answer:
The correct answer is x = -4
Step-by-step explanation:
Step 1: 8x + 1 = -31 <----- This is the original equation.
Step 2: 8x + 1 - 1 = -31 - 1 <----- Subtract 1 from both sides.
Step 3: 8x = -32 <----- Simplify
Step 4: 8x/8 = -32/8
x = -4

Answer:
[tex]5^{\frac{1}{3}}\:\times 25^{\frac{1}{3}}=5[/tex]
Step-by-step explanation:
Given the expression
[tex]5^{\frac{1}{3}}\times \:25^{\frac{1}{3}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^mb^m=\left(ab\right)^m[/tex]
[tex]5^{\frac{1}{3}}\times \:25^{\frac{1}{3}}=\left(5\times \:25\right)^{\frac{1}{3}}[/tex]
[tex]=125^{\frac{1}{3}}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:125=5^3[/tex]
[tex]=\left(5^3\right)^{\frac{1}{3}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc}[/tex]
[tex]=\left(5^3\right)^{\frac{1}{3}}=5^{3\times \frac{1}{3}}=5[/tex]
Thus,
[tex]5^{\frac{1}{3}}\:\times 25^{\frac{1}{3}}=5[/tex]
i require help (why this stuff so hard)
Answer:
x should be -3
Step-by-step explanation:
f(x) = 5/3x + 10
f(-3) = (5*-3)/3 + 10
f(-3) = -15/3 + 10
f(-3) = -5 + 10
f(-3) = 5
g(x) = -2x - 1
g(-3) = -2(-3) - 1
Negatives cancel out
g(-3) = 2(3) - 1
g(-3) = 6 - 1
g(-3) = 5
5 is equal to 5, so x should be -3 in this case.
manuel has $15 to spend.on apps and music. Apps cost $2 each and songs cost $1 each. If x represents the number of apps purchased and y represents the number of songs purchased, write a linear equation that represents the combination of apps and songs manuel can purchase.
Answer:
2x + y = 15
Step-by-step explanation:
Total amount with Manuel = $15
Cost of apps = $2
Cost of song = $1
x = number of apps purchased
y = number of songs purchased
Cost of apps × number of apps purchased + Cost of song × number of songs purchased = Total amount with Manuel
2*x + 1*y = 15
2x + y = 15
The linear equation that represents the combination of apps and songs manuel can purchase is 2x + y = 15

What is the surface area and volume of an rectangular prism with sides 6
The surface area and volume of the rectangular prism are equal to 216 square units and 216 cubic units, respectively.
What are the surface area and the volume of a rectangular prism?Despite the brevity of the statement, we can find the answer by considering the rectangular prism as a cube, that is, every side has a measure of 6 units. The volume is equal to the product of the base area and the height of the prism and the surface area is equal to the sum of the areas of the six faces:
V = 6³
V = 216
A = 6 · 6²
A = 6³
A = 216
The surface area and volume of the rectangular prism are equal to 216 square units and 216 cubic units, respectively.

Mia lives on a farm and has 21 bulls and 21 cows. What percentage of the bovine population is bulls? Please explain how to get your answer as simple as possible! Thank you :)
Answer:
50%
Step-by-step explanation:
To find the percentage of something, you need to put the thing over the total as a fraction, then multiply that fraction by 100%.
Percentage of the bulls = [tex]\frac{21}{21+21}[/tex] × 100%
= [tex]\frac{21}{42}[/tex] × 100%
= 50%

Vertical Angles - Angles that are directly opposite of each other are congruentStep-by-step explanation:
Step 1: Set Up Equation
(x + 7)° = (5x - 49)°
Step 2: Solve for x
Subtract x on both sides: 7 = 4x - 49Add 49 on both sides: 56 = 4xDivide 4 on both sides: 14 = xRewrite: x = 14Step 3: Find angle measure
