<u>Answer-</u>

<em>The value of a is </em><em>-2</em>

<u>Solution-</u>

The vertex form of parabola-

y=a(x-h)^2+k

Where, vertex is at (h, k)

Given that the vertex is at (6, 2), so equation would be

y=a(x-6)^2+2

As the y intercept is the point which lies on the parabola, so it must satisfy the parabola equation.

\Rightarrow -70=a(0-6)^2+2

\Rightarrow -70-2=a(-6)^2

\Rightarrow a(6)^2=-72

\Rightarrow 36a=-72

\Rightarrow a=-2

Hello,
++++++++++++++++
f(x)=a(x-6)²+2
f(0)=-70==>a(-6)²+2=-70===>36a=-72==>a=-2

Geraldo recently saw a newspaper ad for a new version of his laptop. the projected price is $400.00, and the laptop will be out
Tanya [424]

The amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad is $ 390.24.

Given that:-

Price of the laptop after 1 year = $ 400.

Inflation rate = 2.5 %

We have to find the amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad.

Let the price he had to pay be x.

Hence, we can write,

x + (x*(2.5)*1)/100 = 400

x(1 + 1/40) = 400

x(41/40) = 400

x = 400*40/41 = $ 16000/41 = $ 390.24.

Margo is practicing her free throws for basketball
kipiarov [429]

Answer:

16

Step-by-step explanation:

Well if you think about it, if she has a total of 10 attempts she has to make 8 of them to make it on the team. Now the total attempts is double so we double the number of throws she needs to make in order to make the team so to do this we would do 8*2 which is 16. She needs to make 16 throws to make it on the team.

How to solve 10m-2/5=48/5
Romashka [77]

Answer:

Step-by-step explanation:

10m-2/5=9 and 3/5

10m-2/5=9.6 (where 9 and 3/5 is equal to 9.6)

50m-2=48 (i multiplied 10m by 5 and 9.6 by 5)

50m=50 ( i added 2 to both sides)

m=1 ( i divided by 50 to both sides to find m)
