If a < 0 then the graph opens_____​

Answers

Answer 1

Answer:

down

Step-by-step explanation:

Assuming this is for a parabola

a>0 the graph opens up

a < 0 the graph opens down

( negative is a frown)

Answer 2

> means the line is curving downwards.

< means the line is curving upwards.

Assuming that this is a parabola, the inequality a > 0 means that the line is curving in a downward form. This inequality will also have a maximum.

Best of Luck!

Faron wants to paint the four walls in his bedroom. The room measures 12 ft long, 10 ft wide and 8 ft high. There are two doors that each measure 3 ft by 7 ft and a window that measures 3 ft by 4 ft. If Faron does not paint the doors and window, what is the total area he will paint?

Answers

Answer:

319 square feet.

Step-by-step explanation:

The walls of the room (the ones on the long side) have an area of 12 x 8 = 96 square feet each one. Thus, their area is 96 x 2= 192 square feet.

The other two walls have an area of 10 x 8 = 80 square feet each one. Thus, their area combined is 80 x 2 = 160 square feet.

Therefore, we have that the total area of the four walls is

192 +160 = 352 square feet

However, we have a door and a window that won't be painted.

The area of the door is: 3 x 7 =21 square feet

The area of the window is 3 x 4 = 12 square feet

Thus, the total amount of area that won't be painted is

21 + 12 = 33 square feet.

So we are going to take the total area minus the area that won't be painted to know the total area that Faron will pain:

352 - 33 = 319 square feet.

Thus, she will paint 319 square feet

A square pyramid is sliced parallel to the base and halfway up the pyramid.
Which of these describes the cross section?

A square smaller than the base
A quadrilateral that is not a square
A square the same size as the base
A triangle with a height the same as the pyramid

Answers

Answer:

A square smaller than the base

Explanation:

A square pyramid is a 3 Dimensional image. When you slice a 3 Dimensional image you form is a 2 Dimensional image for example a rectangle, a square, a triangle e.t.c.

The shape of the cross sections formed after slicing a 3 Dimensional image is dependent on the way it was sliced.

This means it can be sliced horizontally or vertically and this would result in different shapes.

If square pyramid is sliced parallel to the base and halfway up the pyramid, the shape of the cross section formed is a square smaller than the base.

What is the area of triangle ABC?
O 2.5 square units
O 3 square units
O 3.5 square units
O4 square units

Answers

Answer:

3 square units

Step-by-step explanation:

Edge 2021

The area of triangle ABC will be 3 square units. Therefore, option B is the correct answer.

Triangle ABC in the figure below, where b= 3 units and h= 4 units.

The area of the triangle ABC= The area of the right triangle ABD - The area of the right triangle ACD

We know that, area of a triangle = 1/2 ×Base×Height

The area of the right triangle ABD

= 1/2 ×3×4

= 6 square units

The area of the right angled triangle ACD

= 1/2 ×3×2

= 3 square units

Now, difference = 6-3 = 3 square units

Therefore, option B is the correct answer.

Which equation is NOT an example of a linear function?
A) y = 9 - 2x
B) y = 6/X
C) y = x/2 + 9
D) y = 5/6x - 8

Answers

Answer:

B

Step-by-step explanation:

y = 6/x is not  an example of a linear function

Option B is correct

A linear function can be written in the form ax + by = c

Let us consider the options given and see which of them cannot be expressed in the form ax + by + c

For y  =   9  -  2x

This can also be expressed as

-2x + y  =  9

For y  =  x/2  +  9

This can also be expressed as:

x  -  2y  =  - 18

For y  =  5/6 x - 8

This can also be expressed as:

-5x  +  6y  =  -48

Only y = 6/x cannot be expressed in the form ax + by = c. Therefore, y  = 6/x is not an example of a linear function

Ashley has a right triangular Garden in her backyard the longest side of the garden measures 17 yards one of the sizes 10 yards long find the length of the other side of the garden

Answers

Answer....

The answer should be 13.74 yards.

We must apply the pythagorean theorem to solve.

C is the hypotenuse aka the longest side.

Formula: a^2 + b^2 = c^2

a^2 + 10^2 = 17^2

a^2 + 100 = 289

Subtract 100 from both sides.

a^2 = 189

Square root of 189 is approximately 13.74.

3. Six less than twice a number is 17. Which equation could be used to determine the
number, n?
A. 6-2n = 17
B. 2n-6 = 17
C. 6 - 7 n = 2n
D. 2n + 6 = 7​

Answers

Answer & Step-by-step explanation:

n represents our number. So, twice a number would be 2n because twice means multiply by two.

When the problem says 6 less, then it means 6 less than 2n. So, it would look like 2n-6.

FInally, the problem says that all of this equals 17 so 17 would be the result.

So, you answer is 2n-6 = 17. This is answer choice B.
