Answer:

Step-by-step explanation:

Option B is correct, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point and from a fixed straight line which is known as the directrix.

We can start by using the vertex form of the equation of a parabola, which is given by:

y = a(x - h)² + k

where (h, k) is the vertex of the parabola and a determines the shape and direction of the opening of the parabola.

We are given that the vertex is (5, -3),

Substitute h = 5 and k = -3:

y = a(x - 5)² - 3

We also know that the parabola passes through the point (6, 1), so we can substitute x = 6 and y = 1:

1 = a(6 - 5)² - 3

1 = a - 3

a = 4

Substituting a = 4 into the equation

y = 4(x - 5)^2 - 3

Hence, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.

xy = yx

Answer:x + (x +1) + (x +2)= 30.

Step-by-step explanation:Consecutive means one right after the other--such as 4,5,6. So the sum (add all the numbers together) must equal 30. So the equation should read

Step-by-step explanation:

The score John must have on his final exam in order to finish the class with an average of at least 90% is 62%.

In order to determine the score the that John must have in order to make an average of at least 90%, we have to determine the total sum of the scores he already has.

Sum of scores he already has = 87% + 95% + 92% + 89% + 84% = 447

Sum of scores he must have at the end of his sixth test = Average he must have on his average at the end of his final exam x number of exams written. 90 x 6 = 540

In order to determine the score John must have subtract 447 from 540. Divide the answer by 1.5.

540 - 447 = 93%

93 / 1.5 = 62%

Answer:

Step-by-step explanation:

Step-by-step explanation:

just think a little bit.

the balloon goes down 140 feet per minute.

how many feet will it have descended after 2 minutes ?

twice as much, right ?

after 5 minutes ? 8 minutes ? 10 minutes ? 15 minutes ?

we have to multiply.

simply because we need to maintain the value of the ratio feet/minute at all times.

so, when we multiply the "minute" part (by saying e.g. 5 minutes), we need to multiply the "feet" part with the same factor to keep the overall ratio the same. and then the resulting "feet" part gives us the answer.

so, after 2 minutes that means

140 ft / 1 min × 2/2 = 280 ft / 2 min

=> it descended 280 ft.

so, it's height is then at that moment

2520 - 280 = 2240 ft

5 minutes

140 ft / 1 min × 5/5 = 700 ft / 5 min

=> it descended 700 ft.

so, it's height is then at that moment

2520 - 700 = 1820 ft

and so on.

we see, that the general equation to determine the actual height (h) of the balloon depending on the passed number of minutes (m) is then

h = 2520 - 140m

so

2520 - 140×2 = 2240 ft

2520 - 140×5 = 1820 ft

2520 - 140×8 = 1400 ft

2520 - 140×10 = 1120 ft

2520 - 140×15 = 420 ft

                              =(5x-3)²+(3x-2)(5x-3)

                              =(5x-3)(5x-3+3x-2)

                              =(5x-3)(8x-5)

Explanation:

Use of a calculator makes quick work of this type of problem

5.25 + 2.98 = 8.23

10.00 - 8.23 = 1.77

-----------

If you want to do this using mental math, then one trick is to do this:

Think of 2.98 as 3.00, then add this to 5.25 to get 8.25. Notice that we're 2 cents too high (because of the jump from 2.98 to 3.00), so we need to subtract 2 cents from 8.25 to get 8.23

So that's a fairly quick way to add those two numbers in your head. The more practice you get, the quicker it will happen.

As for the subtraction part, you have a number of routes. Possibly a quick way is to jump from 23 cents to 30 cents (plus 7), then jump from 30 cents to 100 cents (plus 70). Therefore, we have 7+70 = 77 as the overall jump to get us to the nearest dollar. But we'll need one more extra dollar to end up at $10 exactly.

In other words, the "plus 77 cents" portion only gets us from $8.23 to $9, so that's why we need that extra dollar in change. Therefore, we've computed $1.77

I apologize for being a bit wordy. Despite being a bit long-winded, this mental math should come fairly quickly after enough practice.

Given-

Cost of milk 4 years ago = £1.05

To find-

Percentage increase in cost

Solution-

Increase in cost = £ ( 1.26 - 1.05 )

→ £ 0.21

Percentage increase :-

[tex] \frac{0.21}{1.05} \times 100[/tex]

[tex]→ 20[/tex]

Therefore, Percentage increase of the cost of milk over 4 years is 20% .

y = 110

X = 80

angle b is the same value as y so the value of that is 110

Kite total angle must be 360 so if you add 110+110+60 will give you 280. Minus that with 360 will give you X which is 80.

Answer:

x = 3

Step-by-step explanation:

Let's solve your equation step-by-step.

4x+3=7x−6

Step 1: Subtract 7x from both sides.

4x+3−7x=7x−6−7x

−3x+3=−6

Step 2: Subtract 3 from both sides.

−3x+3−3=−6−3

−3x=−9

Step 3: Divide both sides by -3.

-3x ÷ -3 = x

-9 ÷ -3 = 3

x = 3
