Answer:

20 inches

Step-by-step explanation:

Since the cape is trapezoid shaped and has an area of 600 in², the area of a trapezoid is given by

A =1/2(a + b)h where a = length along the top of the cape = 24 in, b = length along the bottom of the cape = 36 in and h = height of the cape

So, h = 2A/(a + b)

= 2 × 600 in²/(24 in + 36 in)

= 1200 in²/60 in

= 20 in

So, the height of the cape is 20 inches

What are the first 3 terms in. t(n)=-2n+7

seropon [69]

Answer:

The first 3 terms of the sequence $t(n)=-2n+7$ are:

$5, 3, 1$

Step-by-step explanation:

Given the sequence

$t(n)=-2n+7$

Here $n$ represents any term number in the sequence

Determining the first term

substitute n = 1 in the sequence to determine the first term

$t(n)=-2n+7$

$t(1)=-2(1)+7$

$t(1)=-2+7$

$t(1) = 5$

Determining the 2nd term

substitute n = 2 in the sequence to determine the 2nd term

$t(n)=-2n+7$

$t(2) = -2(2) + 7$

$t(2) = -4 + 7$

$t(2) = 3$

Determining the 3rd term

substitute n = 3 in the sequence to determine the 3rd term

$t(n)=-2n+7$

$t(3) = -2(3) + 7$

$t(3) = -6 + 7$

$t(3) = 1$

Therefore, the first 3 terms of the sequence $t(n)=-2n+7$ are:

$5, 3, 1$

If you have two pennies, the probability of both coming up heads when flipped is _____.

Juli2301 [7.4K]

There are four side to 2 pennies
both (2) coming up head out all the side (4)
there is a 2/4 chance then simplify by dividing by 2/2 and get ½
so you have ½ chance of both becoming heads

Hope this helps :D

If f(x) = 3x - 1 and g(x) = x + 2, find (f - g)(x).

Marina86 [1]

Answer:

$\boxed{\sf (f - g)(x) = 2x - 3}$

Given:

f(x) = 3x - 1

g(x) = x + 2

To Find:

(f - g)(x)

Step-by-step explanation:

$\sf (f -g)(x) = f(x) - g(x) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =(3x - 1) - (x + 2) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3x - 1 - x - 2 \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =3x - x - 1 - 2 \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =(3x - x) - (1 + 2) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =2x - (1 + 2) \\ \\ \sf \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: =2x - 3$
