Simplify the expression\(\frac{2x^{-1}y}{x^3z}\) for \(x=2\), \(y=8\), and \(z=-1\).

Answers

Answer 1

2 x ⁻¹ y / (x ³ z) = 2 y / (xz)

… = 2 × 8 / (2⁴ × (-1))

… = 16 / (-16)

… = -1

Answer 2

Step-by-step explanation:

2 x ⁻¹ y / (x ³ z) = 2 y / (x ⁴ z)

… = 2 × 8 / (2⁴ × (-1))

Find the surface area of the prism.

Answers

Answer:

326m²

Step-by-step explanation:

Find the area of each side and find the total sum from each individual area:

2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326

So the surface area of the prism is 326m²

Find the area of the figure

Answers

Answer:

  89 m²

Step-by-step explanation:

It should be no surprise that the area can be found as the difference between the area of the enclosing rectangle and the area of the triangular cutout.

The rectangle area is given by ...

  A = LW

  A = (13 m)(8 m) = 104 m²

The base width of the triangular cutout is 13 m - 4 m - 4 m = 5 m. The area of that cutout is given by ...

  A = 1/2bh

  A = 1/2(5 m)(6 m) = 15 m²

Then the area of the shaded figure is ...

  104 m² -15 m² = 89 m²

How is the graph of the parent function y= hurrrr!!!x2 transformed to produce the graph of y= 3(x+1)2? It is translated 1 unit right and compressed vertically by a factor of 3. © It is translated 1 unit left and compressed vertically by a factor of 3. Olt is translated 1 unit right and stretched vertically by a factor of 3. It is translated 1 unit left and stretched vertically by a factor of 3.​

Answers

Answer:

3.

Step-by-step explanation:

The graph is being moved to the left and then stretched by a factor of three. If it were to be compressed than the 3 would be 1/3.

The graph of the parent function is translated to 1 unit left and compressed vertically by a factor of 3.

Option B is the correct answer.

What is translation?

It is the movement of the shape in left, right, up, and down direction.

The translated shape will have the same shape and shape.

There is a positive value when translated to the right and up.

There is a negative value when translated to the left and down.

We have,

The graph of the parent function y = x² can be transformed to produce the graph of y = 3(x + 1)² by translating it 1 unit to the left and stretching it vertically by a factor of 3.

Here's why:

The (x + 1) part inside the square means that the graph is shifted 1 unit to the left.

The exponent of 2 means that the graph is squared, just like the parent function.

The coefficient of 3 in front of the square means that the graph is stretched vertically by a factor of 3.

Therefore,

It is translated 1 unit left and compressed vertically by a factor of 3.

Naomi's fish is 40 millimeters long. Her guinea pig is 25 centimeters long.
How much longer is her guinea pig than her fish?

Answers

Explanation 1:

Her guinea pig is

25 cm  long.

25 cm = 250 mm

Her fish is  40 mm long, so her guinea pig is longer than her fish by

25 cm − 40 mm = 250 mm − 40 mm = 210 mm= 21 cm

Explanation 2:

First, lets convert the length of Naomi's guinea pig from cm to mm.

1 cm=10 mm

We can multiply each side of the equation by 25 to obtain the length of the guinea pig in mm.

25 × 1 cm = 25 ×  10 mm

25 cm = 250 mm

Because we have a length of the guinea pig and the fish in a common metric we can subtract the two values: 250 mm − 40 mm = 210 mm The guinea pig is 210 millimeters longer than the fish. Or, if we want to convert this to centimeters we can divide by 10: 210 millimeters 10 = 21 centimeters

Hope this helps have a good day/night!

What is the Linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given a data set of the number of text messages sent (x) and text messages received (y) by 10 students in a half hour.

so

x     y

0    2

5    1

6    4

8    12

11    11

12    13

15    11

17    20

21    22

24    23

Where M of x = 11.9

also the M of y = 11.9

Sum of X = 119

Sum of Y = 119

Mean X = 11.9

Mean Y = 11.9

The sum of squares (SSX) = 504.9

The sum of products (SP) = 504.9

Regression Equation = ŷ = bX + a

b = SP/SSX = 504.9/504.9 = 1

a = MY - bMX = 11.9 - (1*11.9) = 0

ŷ = 1X - 0

Thus the equation of line best fit will be y = x.
