If the square below is enlarged by a scale factor of 2, what will be the area of the new square? 184 square units 188 square units 192 square units 196 square units

Answers

Answer:

256square units

Step-by-step explanation:

Since we are not given a diagram. Let us assume the side length of the given square is 8 units

If the  the square is enlarged by a scale factor of 2, the side length of the new square will be 2 * 8 = 16units

Since area of a square = L²

Hence the area of the new square =  16²

area of the new square =  256 square units

Hence the area of the new square is 256square units

Note that the side length of the original square was assumed. The values can change depending on the side length of the original square before enlargement

Use inductive reasoning to describe the pattern. Then find the next two numbers in the pattern. 4, 6, 9, 13, . . .


A.
Add 2 to the first term, 3 to the second term and continue, adding 1 more each time; 18, 24.


B.
Add 2 to the previous term; 15, 17.


C.
Add 12 of the previous term; 19.5, 29.25

Answers

Answer:

A.

Explanation:

4 goes up 2 to 6. 6 goes up 3 to 9. 9 goes up 4 to 13. Therefore, you can expect 13 to go up 5 to 18, and 18 to go up by 6 to 24.

Gilbert purchased a car for 34000. The car depreciates at a rate of 14% per year. The exponential function that represents this situation is y = 34000(0.86)^x.

What is the change factor for this function?

Answers

Answer:

.86

Step-by-step explanation:

Exponential function formula

[tex]y = a ( 1 + or - r ) ^t[/tex]

where a = initial value

r = rate of change

and t = number of years

given the equation y = 34000(0.86)^x.

r = .86

Hence the change factor is .86

When examining the formula of a function that is the result of multiple transformations, how can you tell a reflection with respect to the x-axis from a reflection with respect to the y-axis

Answers

Answer:

For a function f(x), a reflection across the y-axis is written as:

g(x) = f(-x)

While a reflection across the x-axis is written as:

g(x) = -f(x)

So, if the negative sign is outside the transformation, like in:

g(x) = -f(x + 2) - 8

We can conclude that this is a reflection over the x-axis.

While if the "x" inside the function has a negative sign, like in:

g(x) = 5*f(-x + 4) - 3

The reflection is over the y-axis.

Answers

Answer:

√41

Step-by-step explanation:

Use a² + b² = c²

a = 4

b = 5

4² + 5² = c²

4² = 16

5² = 25

16 + 25 = c²

41 = c²

You need to get ² away from c, so square root both sides.

√41 = √c²

√41 = c

√41 is in its simplest form, so it is left as √41.

Hi, I took the test and this is the answer. If its K12 then I'm 100% its correct.

The values that can be use for a, b and c in the equation 2x² + 7x − 5 = 0 are a = 2, b = 7, c = -5

Quadratic equation formula

The quadratic equation formula is represented as follows:

ax² + bx + c

where

a, b and c are unknown numbers. a is not 0x  = unknown

Therefore, lets model the equation to 2x² + 7x − 5 = 0 to ax² + bx + c

Hence,

a = 2

b = 7

c = -5
