7. Find the value of Z in the following equation: 8Z = 64.

Answers

Answer 1

Answer: z=8 because you have to get z by itself therefore you have to divide 8 on both sides leaving z to equal 8

Answer 2

Answer: z = 8 is the answer

I hope this helps

If g(x) =x2 + 2 find g(3)

Answers

Hey there! :)

Answer:

g(3) = 11.

Step-by-step explanation:

Given g(x) = x² + 2

Plug '3' into 'x' to solve for g(3):

g(3) = (3)² + 2

g(3) = 9 + 2

g(3) = 11.

Answer: g(3)=8

Step-by-step explanation:

If g(x)=x2+2 and you wish to find g(3), you simply sub in the 3 from g(3) into the x from the original equation, making it g(3)=3x2+2. 3 times 2 is 6, plus 2 equals 8.

Which number in the monomial 125x18y3z25 needs to be changed to make it a perfect cube?

Answers

To make the monomial 125 x^18 y^3 z^25 a perfect cube, the entire expression should be reduced to a rational number when the cube root is taken. For the constant 125, the cube root is 5, so it doesn't need to be changed. For the variables, the exponents should be divisible by 3. The exponent of z is not divisible by 3. It can be subtracted with 1 or added with 2 to make the expression a perfect cube.

The number in the monomial 125x¹⁸y³z²⁵ that needs to be changed to make the expression a perfect cube is 25

Data obtained from the question

Monomial = 125x¹⁸y³z²⁵
Number to be changed =?

How to determine the number to be changed

To determine the number to be changed in order to obtained a perfect cube, we shall determine the cube root of each entity. This is illustrated below

Cube root of 125

³√125 = 5

Cube root of x¹⁸

³√x¹⁸ = x⁶

Cube root of y³

³√y³ = y

Cube root ofz²⁵

³√z²⁵ = z^(25/3)

From the illustration above, we can see that 25 is not a perfect cube.

Thus, 25 needs to be changed in order for the expression 125x¹⁸y³z²⁵to be a perfect cube

A parallelogram has a base of 16 inches and a height of 11.7 inches. What is the area of the parallelogram?

Answers

Answer:

A = 187.2 inches²

Step-by-step explanation:

the area (A) of a parallelogram is calculated as

A = base × height

substitute base = 16 inches and height = 11.7 inches into the formula for A

A = 16 × 11.7 = 187.2 inches²

The function below models the correlation between the number of hours a plant is kept in sunlight (x) and the height (y), in mm, to which it grows:y = 4 + 2x
What does the y-intercept of this function represent?
The original height of the plant was 4 mm.
The original height of the plant was 2 mm.
The height of the plant increases by 2 mm for every hour of sunlight it receives.
The height of the plant increases by 4 mm for every hour of sunlight it receives.

Answers

Remember that the y-intercept is obtained when the value of x is set to zero. This means that the y-intercept is the value of the height without sunlight yet. This also refers to the original height of the plant. This gives:

y = 4 + 2(0) = 4

So, the original height of the plant is 4 mm.

The formula also indicates that when sunlight is present, a height of 2mm is increased every hour of sunlight exposure.

Answer:The original height of the plant was 4 mm.
