What is the y-intercept, axis of symmetry and vertex of the following function?
[tex]F(x)=-3x^{2} -6x-5[/tex]

Answers

Answer 1

Answer:

Y-Intercept: -5

Axis of symmetry: -1

Vertex: (-1,-2)

Step-by-step explanation:

Y- intercept is is always the number without a variable

Axis of symmetry is the x cordirant of the vertex

Vertex: You can turn the equation into vertex form

(photo example below) (IMPORTANT: once you turn your equation into vertex form, remember that the number inside the prencencys has to be turned to the opposite sign (-/+) when you put it as a coordinate)

Answers

Part B: Lily walked 3 units up and 1 unit right to get from the park to the market.

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

position of park: (2, 5)

If moved 3 units up. There will be change in y-axis. ⇒ (5+3) = 8

If moved 1 units right. There will be change in x-axis. ⇒ (2+1) = 3

So market position: (3, 8)

Answer:

if you go up 3 units that puts you at 2,8 then go over right 1 puts you at 3,8 which means x=3 and y=8

A spinner is divided into 8 identical sectors and labeled 1 through 8.

How many spins are expected for a multiple of 3 to be spun 6 times?

Select from the drop-down menu to correctly complete the sentence.

The spinner is expected to have to spin approximately (12,16,24,28)
times for a multiple of 3 to be spun 6 times.

Answers

Answer:

24

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

If there are 8 sections, there is a 1 in 8 chance of getting each section. Consider multiples of 3 ⇒ 3, 6. And to spin that multiple 6 times, you need to multiply the number of sections by the number of multiples. The number of sections(nos) is 8, and the number of multiples(nom) is 3.

[tex]nos * nom = 24[/tex]

Answer:

24 is the correct answer.

The speed of the jet Alyssa flew on from Boston to London was 480 mph. On her return flight, the speed of the jet was 600 mph with a tail wind. What was Alyssa's average speed on the round trip? Round your answer to one decimal place.

Answers

Answer:

533.3 MPH

Step-by-step explanation:

Because the round trip was divided into two segments with varying speeds, you can name the first one (480 MPH) x, and the second one, (600 MPH) y. Then you can use the formula 2xy/(x+y) and put the values in. You should get 576000/1080. After you solve it, you will get 533.333333333... But the problem has not been solved yet, because you have to round 533.33333... to the nearest tenth place, which is .3. Then you should get the answer 533.3 MPH.

Which of the following is NOT a way of calculating slope?

A
m = rise / run
B
m = change in y / change in x
C
m = y2 - y1 / x2 - x1
D
m = 0 - y / 0 - x

Answers

d bc the rest that’s how you find slope

Answer:

D. m = 0 - y / 0 - x

Step-by-step explanation:

It is not a way of calculating the slope.

The other ways :

A. m = rise / run [correct]B. change in y / change in x [correct]C. y₂ - y₁ / x₂ - x₁ [correct]

All of these methods represent the same way, but represented in different forms, to find the slope.

Hence, only D is not a way of calculating the slope.

Answers

Answer:

Answers A and B respectively

Step-by-step explanation:

In the first pic, they are asking you for the value of the function at the points x = -1 and x = 5. Then you are asked to subtract your results. When the value of 'x' is -1, the 'y' value is 3. When the value of 'x' is 5, the 'y' value is -4. Therefore:

[tex]f(-1)-f(5)=3-(-4)=7[/tex]

Answer A

For the second problem, they are saying that the line connecting points A and B is undefined. This means the slope is undefined along that line. An undefined slope is due to a zero in the denominator. Begin by taking the change in 'y' over the change in 'x' to get:

[tex]\frac{y_1-1}{x_1+2} =m[/tex]

In order for our slope 'm' to be undefined, set the denominator to zero and see at what 'x' value this occurs at:

[tex]x_1+2=0[/tex]

[tex]x_1=-2[/tex]

Then they say that the line connecting points C and D is zero. A zero slope would mean a zero in the numerator. Again, begin by taking the change in 'y' over the change in 'x' to get:

[tex]\frac{3-y_2}{-5-x_2} =m[/tex]

Set the numerator equal to zero to get:

[tex]3-y_2=0[/tex]

[tex]y_2=3[/tex]

Elena wants to create a triangle shaped garden that has an area of 36 square feet Name all the different dimensions her triangle can be in feet. Pls help​

Answers

Answer:

Base = 18  Height = 4 (this is an example)

Step-by-step explanation:

Given that the triangle has an area of 36 square feet, and that the triangle area formula is A=1/2bh (b being the base, and h being the height), we can fill in the formula to get the dimensions.

To find the given numbers, we need to find what numbers are divisible to by 2 to get 36. For instance using the formula A=1/2bh, we can plug in the factors that make up 72 (if you divided it by two you will get 36). Example of this is 18x4, so we can plug it into the equation to prove it through factor trees (feel free to reach out if you have a question about those). Plugging 18 and 4 will give 18x4 divided by 2 = 36.

Across the top: 8, 9, 2

Down the side: 4, 3, 6

8 x 4 = 32

9 x 4 = 36

2 x 4 = 8

4 x 8 = 32

3 x 8 = 24

6 x 8 = 48

Hope this helps!

Answer:

Answer is in the file/picture below

Step-by-step explanation:

To start, we can See that 4 times something makes 36, so we can do 36/4 to get 9. (Top 3rd slot)  4 times 9 equals 36.

Next, we can do the 4th slot at the top. We can see that 4 times something makes 8. So, we can do 8/4 to get 2.  2 times 4 equals 8.

Next, we can do the first slot in the third row. We can see that 8 times something equals 24. So we can do 24/8 to get 3.  8 times 3 equals 24.

Lastly, we can do the first slot in the bottom row. We can see that 8 times something makes 48. So, we can do 48/8 to get 6.  8 times 6 equals 48.
