The correct answer is y= 0.513(1.833)^x
Explain
We will use the equation on this form
Y=ab^x
Let’s us plug in the coordinates of first point
(X, y) , ( 9, 120)
We will have
Y=ab^x
120= ab^9
Our equation for a will be
Ab^9 = 120
ab ^9 / b^9 = 120/ b^9
a = 120/ b^9
So will have
Y= 120/ b^9 • b^x
Then we will plug in coordinates for the second point
( x,y) = ( 10, 220)
We will have
Y= 120/b^9 • b^x
220 = 120/b^9 • b^10-9
220= 120b
Divide both side by 120
B= 11/6
B= 1.833333 = 1.833
Let’s plug in the value b=11/6 to our equation for a
A= 120/b^9
A= 120/ 11/6^9
A= 120/11^9/6^9
A=120 • 6^9 / 11^9
= 0.51285 which equal to 0.513
So therefore the answer is
Y= 0.513(1.833)^x
I hope this help you

Answer:
Your correct answer is going to be the third option
Step-by-step explanation:
The trapezoid has two right triangles each with one side of length (13-9)2 = 4/2 = 2.
The other side of each right triangle is such that tan 60° = Heigth / 2
Then height = 2*tan60°.
The area of the trapezoid is height * (base 1 + base 2)/2
Then area = 2*tan (60°) * (13+9)/2 = 38.11
Answer:
She could divide 9.42 by Pi to find the radius, then multiply 9.42 by the radius.
(Last option)
Step-by-step explanation:
We need the formula for the area of a circle:
A = πr²
Remember r² = r × r
So you could rewrite the formula like this:
A = π × r × r
If π × r = 9.42, then the area becomes:
A = 9.42 × r
"<em>Then multiply 9.42 by the radius</em>".
To find "r", divide 9.42 by π.
π × r = 9.42
r = 9.42/π
"<em>Divide 9.42 by Pi to find the radius</em>".
