The answer is -110.
This is because -55-55=-110.
You have to put -55-55 because the question is asking for you to multiply -55 twice, which is technically-55-55.

Answer:

Part a) The rule of the sequence is $A(n)=50(0.52^{n-1})$

Part b) The height of the ball will be $13.52\ cm$

Step-by-step explanation:

Part a) Write a rule for the sequence using centimeters. The initial height is given by the term n = 1.

we know that

In a <u>Geometric Sequence</u> each term is found by multiplying the previous term by a constant called the common ratio (r)

In this problem we have a geometric sequence

Let

n-----> the number of path

a1 ----> is the initial height

r -----> the common ratio

we have

$a1=0.5\ m=0.5*100=50\ cm$

$r=52\%=52/100=0.52$

The rule for the sequence is equal to

$A(n)=a1(r^{n-1})$

substitute

$A(n)=50(0.52^{n-1})$

Part b) What height will the ball be at the top of the third path?

For n=3

substitute in the equation

$A(3)=50(0.52^{3-1})$

$A(3)=50(0.52^{2})$

$A(3)=13.52\ cm$

What is the degree of the polynomial and what the y-intercept

Arada [10]

Answer:

Polynom degree: 5

Y intercept point: (0, 80)

Step-by-step explanation:

P(x)=(x+5)(x+4)²(x+1)²

When you expand, the highest power of x is 1 for first term (x+5), 2 for second term (x+4)² and again 2 for (x+1)². Overall, x⁵ will be the x term with highest power. So the degree of the polynom is 5.

The y intercept, i.e. intersection with OY axis, happens for x=0. Thus, P(0)=5×4²×1²=5×16=80. The y intercept point is (0, 80)

19. What is the equation of the line in slope-intercept form that passes through the point (24,9) and 1/8

Y_Kistochka [10]

Answer:

y=1/8x+6

Step-by-step explanation:

y-y1=m(x-x1)

y-9=1/8(x-24)

y=1/8x-24/8+9

y=1/8x-3+9

y=1/8x+6
