Answer:
D
Step-by-step explanation:
solve square root of 3x plus 1 = 4:
D is correct and results in 3x + 1 = 16; after this we subtract 1 from both sides and end up with 3x = 15, or x = 5.
<span>We first need to figure out how much insurance Susan pays annually. For every $100, she pays 30 cents. Well, let's pretend that we have her entire home's value in 100 dollar bills. There will be 4830 bills. On each of those bills, she will pay 30 cents. If we multiply .30 x 4830 we get $1449. This is how much she pays all year- to find out how much she pays each month, we divide by 12. This gives us 120. 75. We include this on her monthly mortgage payment: 120.75 + 2128 and we get A) 2248.75.</span>
PART A:
The x-intercept at 0 shows the location where the ball was kicked. The x-intercept at x = 16 shows the location where the ball hit the ground.
The maximum value represents the highest point of the ball.
The interval where the function is increasing is 0<x<8. Between this interval, the height of the ball measured from the ground is increasing.
The interval where the function is decreasing is 0<x<16. Between this interval, the height of the ball is decreasing.
PART B:
Reading from the graph
When x = 8, y = 10 ⇒ let this be x₁ = 8 and y₁ = 10
When x = 13, y = 6 ⇒ let this be x₂ = 13 and y₂ = 6
The rate of change = (y₂-y₁) / (x₂-x₁)
The rate of change = (6 - 10) / (13 - 8)
The rate of change = -4 / 5 = -(4/5)
Answer:
4.4
Step-by-step explanation:
I believe the answer is 4.4 or 22/5.
