Step-by-step explanation:

Step 1: Define function

Vertex Form: f(x) = -2(x - 3)² + 7

Step 2: Find Standard Form

Answer:

A. if not then b.

Step-by-step explanation:

The change in the X - coordinates from one point to another on a line is given by x₂ - x₁ = Δx.

We have the change in the X - coordinates from one point to another on a line.

In a slope ratio, the change in the X - coordinates from one point to another on a line can be represented as -

x₂ - x₁ = Δx

Therefore, the change in the X - coordinates from one point to another on a line is given by x₂ - x₁ = Δx.

Answer:

See the attached image below for the filled out chart.

===================================================

Explanation:

Part 1

Pick any term and subtract off its previous term

So for instance 4.2 - 4.1 = 0.1

Or you could say 4.3-4.2 = 0.1

Whichever pair you pick, you should find that the common difference is 0.1

This means we add 0.1 to each term to get the next term. Therefore, the recursive rule is [tex]a_n = a_{n-1} + 0.1[/tex] which says "add 0.1 to the (n-1)th term to get the nth term". The (n-1)th term is the term just before the nth term.

The first term is [tex]a_1 = 4[/tex] as shown in the given sequence 4, 4.1, 4.2, ...

------------------------------

Part 2

We'll follow the same idea as part 1.

Subtract any two adjacent terms

-10-(-7) = -10+7 = -3

We add -3 to each term to get the next. This is the same as subtracting 3 from each term, which is reflected in [tex]a_n = a_{n-1}-3[/tex]

The first term is [tex]a_1 = -1[/tex]

Everything is summarized in the diagram below.

Step-by-step explanation:

Key:

m = slope

(x₁, y₁) coordinates of the first, lower point.

(x₂, y₂) coordinates of the second, higher point.

Answer:

In simple terms, slope is how steep a line is.

Answer:

Step-by-step explanation:

The remaining work is to identify the values of x that make the factors zero:

4x +45 = 0

  x = -45/4 . . . . negative dimensions are not useful

x -10 = 0

  x = 10

The width is x, so the width is 10.

The length is 4x+5, so the length is 4·10+5 = 45.

The rectangle has a width, x, of 10 and a length of 45.

Answer:

The product can be calculated.

The resulting matrix will have 3 rows and 3 columns.

Step-by-step explanation:

Matrix multiplication

To find the product of two matrices is only possible when the number of columns of the first matrix is equal to the number of rows of the second matrix.

If X is the first matrix with dimensions (n x m) and Y is the second matrix with dimensions (m x p), the product XY is possible and the dimensions of the resulting matrix are (n x p).

Matrix A has two rows and three columns (2x3)

Matric C has three rows and two columns (3x2)

If we wanted to calculate the product CA, the number of columns of C must be equal to the number of rows of A.

Since both numbers are 2, the product can be calculated.

The resulting matrix will have 3 rows and 3 columns.

In third step Alice want to add+21 on both sides but she mistakenly subtract 21 in left side that's why Alice got wrong answer

WRIGHT ANSWER

Answer:

The width is 22.5 feet and the length 45 feet.

Step-by-step explanation:

Let l represent the length of the rectangle and  w represent the width of the rectangle. The cost of the fence (C) is:

C = 2l + 2w + 2l + 6w

C = 4l + 8w

360 = 4l + 8w

360 = 4(l + 2w)

90 = l + 2w

l = 90 - 2w

Area (A) of rectangle = length * width

A = l * w

Put l = 90 - 2w

A = (90 - 2w)w

A = 90w - 2w²

The maximum area is at A' = 0, hence:

Differentiating gives:

A' = 90 - 4w

Put A' = 0

0 = 90 - 4w

4w = 90

w = 22.5 feet

l = 90 - 2w = 90 - 2(22.5) = 45 feet

Hence the width is 22.5 feet and the length 45 feet.

Answer:

the axis of symmerty is 4 and vertex is (4,3) correct me if i am wrong and you can use desmos to help you it is a graphing calculator

Step-by-step explanation:

For the given parallelogram, the measure of angle B is 65° and the measure of angle D is 65°. The answer is the third option.

There are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram.  Each type is defined accordingly to its length of sides and angles. For example, for a parallelogram, its the opposite sides are equal and parallel. For a parallelogram is noted too that the opposite angles are equal.

The question gives the values of the angle B and D in function of n.

Therefore, considering that the opposite angles of the  parallelogram (ABCD)  are equal, so D=B.  Thus,

6n-25=3n+20

6n-3n=20+25

3n=45

n=15°

Replacing the value of n in each angle (B and D). Then,

D=6n-25= 6*15-25= 90-25= 65°

B=3n+20= 3*15+20= 45+20 = 65°

The number of ways of spending Rs. 150 will be 3.

Combination and permutation are two different ways of grouping elements of a set into subsets in mathematics. The elements of the subset can be listed in any order in a combination. The elements of the subset are listed in a specific order in a permutation.

Given that Raman and Raj go to a party each having Rs. 100, If they decide to expend Rs. 150.

The number of the spending will be calculated as,

Raman + Raj = 150

100 + 50 = 150

50 + 100 = 150

75 + 75 = 150
