Determine the direction that this parabola
opens:
y = -5x2 - 10x - 13

Answer:

A. 3(x + 4)

Step-by-step explanation:

All we have to do to get the expression on the other side is to expand the bracket on the left and factorise the expression.

The equation given is:

3(x + 1) + 9 = 0

Expanding the left hand side and factorising:

3x + 3 + 9

=> 3x + 12

=> 3(x + 4)

Therefore, the expression that can be written on the other side is 3(x + 4)

Answer:

[tex]21x^{4}+ 56x^{3}+49x^{2}[/tex]

Step-by-step explanation:

When we multiply the two sides together, we get:

(3x²·7x²) + (8x·7x²) + (7·7x²) =

[tex]21x^{4}+ 56x^{3}+49x^{2}[/tex]

This is the polynomial in standard form.

Answer:

-2,5

Step-by-step explanation:

Answer:

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

Step-by-step explanation:

Answer:

For a rectangle, you get the length and width and multiply them

For a Square, you have to find one side length and mulitply it by itself

or you can split the square with a diagonal into 2 triangles, get the area of each and add them up

or split the square in half and find the area of both rectangles and then add them together

Step-by-step explanation:

For example, if the measure of one side of a square is 5, because all the other lengths are the same, you do 5 times 5 which equals 25 or 5^2 which is 25

Step-by-step explanation:

Answer:

X intercept is (-8,0), Y intercept is (-6,0)

Step-by-step explanation:

The intercept is where the line crosses the X and Y axis, so in this line, the line crosses the x axis at (-8,0) and the y axis at (-6,0).

Answer:

There are two different intercepts in this linear line. The x - intercept would be at (-8, 0), and the y - intercept would be at (0,-6). To find out which is the x - intercept and which is the y - intercept, remember that x is always horizontal and y is always vertical.

C 11

Step-by-step explanation:

2y = 12 – 5x

Let x = -2

2y = 12 - 5(-2)

2y = 12 +10

2y = 22

Divide by 2

2y/2 = 22/2

y = 11

0.4 has 4 tenths

Look at 0.4 as 0.40

Divide the 40 by 10 and get 4

-Hope this helped!

Answer:

The are 4 tenths in 0.4

Step-by-step explanation:

This is because when looking at a place value table the digit 4 is in the tenths column and so means there are 4 tenths.

To work this out you would look at what place are the tenths and then look at the digit in the corresponding place

Answer:

4.5 pi

Step-by-step explanation:

First find the area of a circle with the same radius

The diameter is 6 so the radius is 1/2 d = 1/2(6) =3

A = pi r^2

A = pi (3)^2

A = 9 pi

This is a semi circle of half a circle so the area is 1/2

Answer:

The length and width of the field are 68ft and 32ft respectively

Step-by-step explanation:

Given:

Rectangular Playing Field

Perimeter. P = 200 ft

Required

The dimension of the field (Length and Width)

Let L and W represent the length and the width of the field.

From the question, L is 4 more than twice of W.

This means

L = 4 + 2W

Provided that the playing field is rectangular in shape;

We need to make use of the formula of perimeter of a rectangle.

P = 2(L + W)

Substitute 200 for P

200 = 2(L + W)

Divide through by 2

[tex]\frac{200}{2} = \frac{2(L + W)}{2}[/tex]

100 = L + W

Recall that L = 4 + 2W

Substitute 4 + 2W for L

100 = L + W becomes

100 = 4 + 2W + W

100 = 4 + 3W

Subtract 4 form both sides

100 - 4 = 4 + 3W - 4

96 = 3W

Divide both sided by 3

[tex]\frac{96}{3} = \frac{3W}{3}[/tex]

32 = W

W = 32

Recall that L = 4 + 2W

Substitute 32 for W

L = 4 + 2(32)

L = 4 + 64

L = 68

Hence the length and width of the field are 68ft anf 32ft respectively

Answer:

15,760

Step-by-step explanation:

I just added all of them...

The sticker price we just need to add all the extras to the suggested retail price. The total sticker price would be $15,760.

The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.

To find the sticker price we just need to add all the extras to the suggested retail price:

suggested retail price       $13,760

air conditioner                    $800

cruise control                     $235

custom sound system       $490

destination charge            $475

total sticker price = 13,760 + 800 + 235 + 490 + 475

                              = 15,760

The total sticker price would be $15,760.

The sticker price includes all the extras that the car dealer adds to the MSRP, and is generally the price of ready-to-sell cars.

Answer:

x = 30

y = 15

Step-by-step explanation:

All the angles are 90°, so set 6y and 3x equal to 90, like so:

6y = 90

Divide both sides by 6:

y = 15

Solving for x:

3x = 90

Divide both sides by 3:

x = 30

Step-by-step explanation:

3) in parallelogram opposite angles are equal

6y=90

y=15

x=30

4)In parallelogram ,parallel sides are equal

x=7

y=4

You cannot have the range of a number in negative numbers. The range will always be in positive numbers, and the range will never be in a fraction.

The range of the graph is all real numbers.

Each domain and range are the set of all actual numbers. however, due to the fact, absolutely the fee is described as a distance from 0, the output can only be greater than or identical to zero. The domain is all real numbers since the horizontal extent of the graph is the complete real range line.

Step-by-step explanation: edge 2022

The answer would be options (B) and (D)

A parabola is a U-shaped curve this is drawn for a quadratic function,

f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.

parabola, open curve, a conic segment produced via the intersection of a proper circular cone and a plane parallel to an element of the cone.

On a coordinate plane, a line with a negative slope goes through points (0, 1.5) and (2, 1)

So this is a linear function

On a coordinate plane, a parabola opens up.

Here this is a quadratic function, So this is a non-linear function

Hence, the answer would be options (B) and (D)
