Step-by-step explanation:

Given:

Function 'f' with two variables 'x' and 'y'.

To find:

Function rule if the parent function 'f' is rotated by 270° clockwise.

Solution:

A function given with two variables 'x' and 'y',

f(x,y) → (x, y)

If this function is rotated by 270° clockwise, the function rule will become,

f(x, y) → (-y, x)

Therefore, Option A will be the correct option.

Express the product of 2x^2+6-8 and x+3 in standard form

Gnesinka [82]

Answer:2x3+12x2+10x−24Explanation:The product of these expressions 'means' to multiply them. hence : (x + 3 )(2x2+6x−8) Each term in the 2nd bracket must be multiplied by each term in the 1st.This can be achieved as follows.x(2x2+6x−8)+3(x2+6x−8[2x3+6x2−8x[6x2+18x−24]=2x3+6x2−8x+6xx−24 collect 'like terms'=2x3+12x2+10x−24 is in standard form

Cherylis making candy bags for her friends. She has a bag of candy that has 20 pieces and a bag of candy that has 15 pieces. If

masha68 [24]

Answer:

Each friend will receive 7 candies.

Step-by-step explanation:

Given that:

Number of candies in one bag = 20 pieces

Number of candies in other bag = 15 pieces

Total number of candies = 20 + 15 = 35 pieces

Number of friends = 5

Let,

c be the number of candies each friend will receive.

5c = 35

Dividing both sides by 5

$\frac{5c}{5}=\frac{35}{5}$

c = 7

Hence,

Each friend will receive 7 candies.

Nationwide Insurance would like to perform a chi-square test to investigate whether a difference exists in the proportion of mal

ki77a [65]

Answer:

1

Step-by-step explanation:

There are 2 categories male and female and 1 attribute those who text during driving so the number of cells is 2*1= 2

And degrees of freedom is found by subtracting 1 from k= k-1= 2-1= 1 where k is the number of the categories

The degrees of freedom for this chi square test of proportions is 1

The critical value for ∝= 0.05 is .χ²≥ χ²(0.05,1)= 3.84

The critical value for ∝= 0.01 is .χ²≥ χ²(0.05,1)= 2.71

Which polynomial is factored completely?

nadezda [96]

Answer:

Complete factored: (4x+4)(x+1) and 2x(x²-4)

Step-by-step explanation:

We have to check each option one by one

Option 1: $121x^2+36y^2$

It is sum of two perfect square, As we know sum of two perfect square can't be factored. It is prime equation.

False

Option 2: $(4x+4)(x+1)$

Here we have two factor (4x+4) and (x+1). In both factor degree of x is 1. It is complete factor form.

Complete factor: $4(x+1)(x+1)$

True

Option 3: $2x(x^2-4)$

Here we have two factor 4x and x²-4. For second factor it is further factor. Because it is difference of square. Factor of x²-4 = (x+2)(x-2)

Complete Factor: 2x(x+2)(x-2)[/tex]

True

Option 4: $3x^4-15n^3+12n^2$

Here variable are not same. So, it can't be factor.

False
