graph the following state and show the a h and k values.
y=2(x+3)^2-4

Answers

Answer 1

This equation is in vertex form. Vertex form is y=a(x-h)^2+k, where (h,k) is the vertex. In this equation, h= -3, and k= -4. So, the vertex would be at (-3,-4). A tells us if the parabola will be positive or negative. In this case, it is positive, so the parabola opens upward. Then, you can solve for x-intercept by letting y=0 and solving for x. Then, you can find the y-intercept by setting x=0 and solving for y. Finally, graph the parabola.

Select the correct answer. A model rocket was launched from the top of a building. The rocket's approximate height can be modeled by the quadratic equation h = -4.9t2 + 53.9t + 127.4, where h is the rocket's height, in meters, after t seconds. When factored, this equation is h = -4.9(t - 13)(t + 2). What is a reasonable time for it to take the rocket to land on the ground? Answer A 11 seconds Answer B 13 seconds Answer C 2 seconds Answer D 15 seconds

Answers

Answer:

13 seconds.

Step-by-step explanation:

Given

[tex]h = -4.9(t - 13)(t + 2).[/tex]

Required

Determine a reasonable solution for t

To do this, we equate h to 0.

[tex]h = -4.9(t - 13)(t + 2).[/tex] becomes

[tex]0 = -4.9(t - 13)(t + 2).[/tex]

Divide through by -4.9

[tex]0 = (t - 13)(t + 2).[/tex]

Reorder the expression

[tex](t - 13)(t + 2) = 0.[/tex]

Split

[tex]t-13 = 0[/tex] or [tex]t + 2 = 0[/tex]

This gives:

[tex]t = 13[/tex] or [tex]t = -2[/tex]

But time can't be negative, So:

[tex]t = 13[/tex]

i need help finding the value of x and the measure of each angle

Answers

Answer:

x=7, angle a= 45 degrees, angle b= 65 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65

Answer:

x = 7

m∠B = 65

m∠A = 45

Step-by-step explanation:

So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.

180 - 70 = 110

Now we can set both equations equal to 110.

2 + 9x + 7x - 4 = 110

Now simplify.

2 + 9x + 7x - 4 = 110

2 + 16x - 4 = 110

16x - 2 = 110

+2 +2

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

16x = 112

÷16 ÷16

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

x = 7

So now you can just plug 7 in for x to check your answers

2 + 9(7) = 65

7(7) - 4 = 45

65 + 45 + 70 = 180

Answer:

250x + 525y ≤ 7800

no, 15 refrigerators and 8 pianos will not fit on the truck

Step-by-step explanation:

we know that x is the refrigerators and each one is 250 lbs

this can be written as 250x

we know that y is the pianos and each one is 525 lbs

this can be written as 525y

we also know that "no more than" is the same that as less than equal to

so this can be written as ≤

we can also say that the refrigerators and pianos has to be ≤ 7800

so now we have: 250x + 525y ≤ 7800

plug in 15 to x and 8 to y

250(15) + 525(8) ≤ 7800

3750 + 4200 ≤ 7800

7950 ≤ 7800

this statement is not true so no, 15 refrigerators and 8 pianos will not fit on the truck

Answers

Answer:

15 blue marbles

Step-by-step explanation:

Given that:

A bag contains 6 red marbles.

The Ratio of red to blue marbles is 2:5

Thus, the ratio of red marbles for 6 red marbles in a bag will be = 6/2 = 3

Now; the ratio of blue marbles in a bag containing 6 red marbles = 3 × 5 = 15 blue marbles

Mathematically;

[tex]\dfrac{2}{5} \times \dfrac{x}{x} = \dfrac{6}{blue}[/tex]

So, we are looking for the same number we can multiply for both the numerator and the denominator that can give us the value of 6 in the above numerator to determine the value of the denominator. If we use 3 since 2× 3 = 6

We have:

[tex]\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{blue}[/tex]

[tex]\dfrac{2}{5} \times \dfrac{3}{3} = \dfrac{6}{15}[/tex]

So, there are 15 blue marbles in the bag.

Answers

Answer:

Anniversary sale price= $570

Step-by-step explanation:

Giving the following information:

Purchase cost= $400

Mar-up percentage= 90%

First, we need to calculate the "normal" selling price:

Selling price= 400*1.9= $760

Now, we can determine the anniversary sale price:

Anniversary sale price= 760 - (760*0.25)= $570

A family used a professional decorator to help furnish their new home. The decorator selected $1,580 worth of furnishings. In addition to paying for the purchases, the family paid 4.5% tax on the purchases. The decorator's fee was 12% of the purchases, not including the tax. Write an equation in the form of y=kx to represent the decorator's fee. Then use the equation to calculate the amount of that fee. Round to the nearest hundredths place if necessary.

Answers

Answer:

Step-by-step explanation:

Worth of furnishings = $1580

Tax rate = 4.5%

Tax = 4.5% × $1580 = 0.045 × $1580 = $71.10

Amount paid = $1580 + $71.10 = $1651.10

Since the decorator's fee was 12% of the purchases. This will then be calculated as:

y = kx

where,

y = decorators fee

k = percentage of decorators fee on purchases

x = amount paid

y = 12% × $1651.10

= 0.12 × $1651.10

= $198.132
