What does h(3.2) represent?

marshall27 [118]

Answer:

the height of the rock 3.2 seconds after it is propelled

Step-by-step explanation:

The complete question is

The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot

Let

t------> the time in seconds

h----> the the height of a rock after it is propelled by a slingshot in meters

we know that

$h(t)=-16t^{2} +28t+500$

For $x=3.2\ sec$

Find the value of h(t)

$h(3.2)=-16(3.2)^{2} +28(3.2)+500=425.76\ meters$

therefore

h(3.2) represent the height of the rock $3.2$ seconds after it is propelled

see the attached figure to better understand the problem

Match each expression to its equivalent standard form.

Aleksandr [31]

Let's expand the products they are all in the form

$(a+b)(a-b)=a^2-b^2$

For the first one we have a=x and b=2i:

$(x+2i)(x-2i)=x^2-(2i)^2=x^2+4$

For the second one we have a=x-2 and b=2i:

$(x-2+2i)(x-2-2i)=(x-2)^2-(2i)^2 = x^2-4x+4+4=x^2-4x+8$

For the third one we have a=x+1 and b=i:

$(x+1+i)(x+1-i)=(x+1)^2-i^2=x^2+2x+1+1=x^2+2x+2$

Mrs. Chip bought 2 sheets and a blanket and paid $41. Mrs. Dale bought a sheet and 4 blankets and paid $80.

Katyanochek1 [597]

Answer:

Sheet = $12
Blanket = $17

Step-by-step explanation:

Let the cost of a sheet be s and cost of a blanket be b

2s + b = 41
s + 4b = 80

From the first equation we get:

b = 41 - 2s

Substitute in the second equation

s + 4*(41 - 2s) = 80
s + 164 - 8s = 80
7s = 84
s = 12

Then

b = 41- 2*12 = 17

Which equation represents the situation below if "c" represents the number of chocolate chip cookies?Heather baked 200 cookies o

lisov135 [29]

Answer:

200 - 65 = c

Step-by-step explanation:

You would need to subtract the 65 oatmeal cookies that Heather has from the 200 in total. You would then get how many chocolate chip cookies that Heather would have left. Hope this helped.
