Step-by-step explanation:

Here's an easy way to fold any rectangle of paper into a triangle with three sides the same length.

Fold the paper in half long-ways, then open it out flat.

Fold a bottom corner up to touch the fold line, making a sharp point on the other corner.

Now fold the two RED edges together.

The height of a ball kicked in the air is modeled by the equation h(t) = -2t^2 +8t +24, where h is the height of the ball in fee

Setler79 [48]

Answer:

Step-by-step explanation:

The rate of change in any function is the slope of the line between 2 points. Our points are t = 2 and t = 5. But we know that the slope formula also involves the h's for each of those t's. We need to find them first. The slope formula is

$m=\frac{y_2-y_1}{x_2-x_1}$ , but for us it will look like this (fittted to our needs):

$m=\frac{h_2-h_1}{t_2-t_1}$ . So we need to find those h's.

when t = 2, plug in a 2 for t and solve for h.

Therefore, $h(2)=-2(2)^2+8(2)+24$ and

h(2) = 32 and in coordinate form, (2, 32).

When t = 5, plug in a 5 for t and solve for h.

Therefore, $h(5) =-2(5)^2+8(5)+24$ and

h(5) = 14 and in coordinate form, (5, 14). Now we can plug into our slope formula:

$m=\frac{14-32}{5-2}=\frac{-18}{3}=-6$ , choice B.

The rate of change is -6 which, in words, means that the ball fell 6 feet every 1 second it fell.

A textile corporation buys equivalent with an initial purchase price of $750000. It is estimated its useful life will be 3 years

Rashid [163]

First,we have to find the depreciation, which is 750000-75000=675000. Dividing that by 3 (for 3 years), we get 225000 dollars per year

Evaluate the expression when a= 1/4 and b = 6. 16a2 – 4b=

Degger [83]

Step-by-step explanation:

HERE,

a= $\bold{\dfrac{1}{4} }$

b=6

so,

According to the question, 

$\bold{16a^2-4b }$

$\bold{16\times(\dfrac{1}{4})^2-4\times 6 }$

$\bold{ 16\times \dfrac{1}{16}-24 }$

$\bold{\cancel{16}\times \dfrac{1}{\cancel{16}}-24 }$

$\bold{1-24 }$

$\bold{ -23 }$
