We have the following function:
f (x) = 3/8 (4) ^ x
The function is of the form:
f (x) = A (b) ^ x
Where,
A: initial amount
b: growth factor (b> 1)
x: time variable.
Answer:
f (x) = 3/8 (4) ^ x
It is an exponential function of the form:
f (x) = A (b) ^ x
I can do A, I think.
Part A: Marina rented a coat at $285 for 3 days. If as rents the same coat for 6 days she has do pay a total rent of $510. <span>Write an equation in the standard form to represent the total rent (y) that Marina has to pay for renting the coat for x days.
</span><span>First, find out the base price. If it was $285 for 3 days, then it's: 285/3, which equals $95 per day to rent the coat. Now you can just write the equation. Use the letters x and y to represent the data they want in the equation.
y (total rent) = 95x (x being the number of days). So your equation will be y = 95x, and if someone wanted to solve it they'd just need to give the value of "x"</span>
Answer:
The measure of angle 1 is 115°
Step-by-step explanation:
we know that
If ∠1 and ∠2 are a linear pair
then
∠1 +∠2 =180° -----> supplementary angles
If ∠2 and ∠3 are vertical angles
then
∠2 =∠3
step 1
Find the value of y
we know that
∠2 =∠3
substitute values
(5+4y)°=(6y-25)°
6y-4y=(5+25)°
2y=(30)°
y=15°
step 2
Find the measure of angle 2
∠2=(5+4y)°
substitute the value of y
∠2=(5+4(15))°
∠2=65°
step 3
Find the measure of angle 1
we know that
∠1 +∠2 =180°
we have
∠2=65°
substitute
∠1 +65°=180°
∠1 =180°-65°=115°
