Answer:

(fog)(-3)= 11

Step-by-step explanation:

we have from statement:

f(x) = 7x + 4

g(x) = x + 4

so we have:

(fog)(x)= 7(x+4) + 4

(fog)(-3)= 7(-3+4) + 4

(fog)(-3)= 7(1) + 4

(fog)(-3)= 11

Complete the steps to evaluate the following expression, given log3a = −0.631.
Zielflug [23.3K]

\log _{3}(3)=1 and \log _{3} \frac{a}{3}=-1.631

Solution:

Given value \log _{3} a=-0.631.

To evaluate the expression \log _{3} \frac{a}{3}.

Using logarithmic rule: \log _{b}\left(\frac{M}{N}\right)=\log _{b}(M)-\log _{b}(N)

$\log _{3} \frac{a}{3}=\log _{3}(a)-\log _{3}(3)

We know that \log _{3} a=-0.631.

$\log _{3} \frac{a}{3}=-0.631-\log _{3}(3)

Using another logarithmic rule: \log _{b} b=1

$\log _{3} \frac{a}{3}=-0.631-1

$\log _{3} \frac{a}{3}=-1.631

Hence \log _{3}(3)=1 and \log _{3} \frac{a}{3}=-1.631.

Jesse has 5 and 3/4 dozen eggs. How many eggs does Jesse have?
emmainna [20.7K]
¾ = 75%
so turn 75% into a decimal by dividing by 100 and get .75
then multiply:
.75x12=9
so ¾ of a dozen is 9 eggs
now multiply:
5x12=60 eggs
so now just add 60+9=69
So Jesse has 69 eggs

Hope this helps!! :D

Mandarinka [93]

Answer:

Tyree and all of his friends get 1 ticket for $7. Next they all get 1 snack for $5. Then they all get a drink for $2. So:

1=7

1=5

1=2

Then you take each person (which there are five of then) and you times all five people by 7, 5, 2.

5 x 7=35

5 x 5=25

5 x 2=10

After that you add it all together:

35 plus 25=60

60 plus 10=70

Step-by-step explanation:

your welcome

Which equation represents a circle with a center at (-4, 9) and a diameter of 10 units?
blsea [12.9K]

Answer:

(x+4)^2 + (y-9)^2 = 25

Step-by-step explanation:

We can use the equation (x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

The center is at (-4,9) and the diameter is 10 which means the radius is 10/2 or 5

(x- -4)^2 + (y-9)^2 = 5^2

(x+4)^2 + (y-9)^2 = 25
