Given the equation g(t)=4^t , what is the average rate of change from 0≤t≤2?

andre [41]

Answer:

g(0)=4^0 = 1

g(1) = 4^1 = 4

g(2) = 4^2 = 16

Average :

(1+4+16)/3

=(5+16)/3

=21/3

= 7

Take a sum, divide by 3 because the counted datas are 3.

You are running a concession stand selling hot dogs and sodas. Each hot dog costs $2 and each soda costs $1. At the end of the n

amm1812

Answer:

see the explanation

The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75

Step-by-step explanation:

Let

x ---> the number of hot dogs that were sold

y ---> is the number of sodas that were sold

we know that

You sold a total of 90 hot dogs and sodas combined

$x+y=90$ ----> equation A

You made a total of $105

$2x+y=105$

isolate the variable y

$y=105-2x$ ----> equation B

substitute equation B in equation A

$x+(105-2x)=90$

solve for x

$x=105-90\\x=15$

Find the value of y (equation B)

$y=105-2(15)=75$

therefore

The number of hot dogs that were sold is 15 and the the number of sodas that were sold is 75

Find cos (2 theta angle) if sin (theta angle) =4/5

nataly862011 [7]

Sin(theta) = 4/5, $cos^{2} (theta)=1-( \frac{4}{5})^{2} = 1 - \frac{16}{25} = \frac{9}{25}$ We will switch it to formula: $cos(2 theta)=cos^{2} (theta)-sin^{2} (theta)= \frac{9}{25} - \frac{16}{25}=- \frac{7}{25}$
