Answer:
C. y = x^2 + 4x.
Step-by-step explanation:
Area of a trapezoid = (h/2)(a + b) where h is the altitude and a and b are the lengths of the parallel sides.
So here
Area y = (x/2)(8 + 2x)
= 8x/2 + 2x^2/2
= 4x + x^2.

Savannah has a principle of 15000 with a 4.25% and saves 1,275 in interest. How long is she saving for
Answers
Answer:
5.73 years
Step-by-step explanation:
Considering she saved 4.25% in each year of the amount $15000.
So, we have to calculate in what time her saving reaches $1275, if she save each year.
it becomes question of simple interest in which
SI = $1275, Principal P= $5000, time T, rate R = 4.25%
we know SI = PRT/100
1275 = 5000×4.25×T/100
⇒T = 1275×100/(5000×4.25)
⇒ T= 5.73 years

A ball is thrown into the air with an upward velocity of 44 ft/s. It’s height h in feet after t seconds is given by the function h=-16t^2 +44t+5. How long does it take the ball to reach its maximum height? What is the balls maximum height?
Answers

Answer:
1.375 seconds35.25 feetStep-by-step explanation:
A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).
Here, we have ...
h = -16t^2 +44t +5
t = -44/(2(-16)) = 11/8 = 1.375
It takes 1.375 seconds for the ball to reach its maximum height.
The height at that time is ...
h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25
The maximum height is 35.25 feet.
Write an equation whose graph is a line perpendicular to the graph of x = -7 and which
passes through the point (-7,1).
Answers
Answer:
y = 1
They will pass through each other perpendicular, also you can look up graph in chrome and use a free graph.
Step-by-step explanation:
The equation of the line perpendicular to the graph of x = -7 and which passes through the point (-7,1) is y=1.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
As the equation x=-7 will represent a straight verticle line at x=-7. Therefore, the line that will perpendicular to this line will be a horizontal line. Since it is given that the line must intersect at (-7,1). The horizontal line should be at y=1.
Hence, the equation of the line perpendicular to the graph of x = -7 and which passes through the point (-7,1) is y=1.

Rate of interest = 6.2% = 0.062
Time = 7 years

Inetrest = 750 x 0.062 x 7
= $ 325.5
Hence, you will receive $ 325.5 as interest at the end of 7 years.
You have $80 in your bank account each week plan to deposit $9 from your allowance and $25 from your paycheck. The equation b=80+(25+9)w gives the amount b in your account after w weeks. How many weeks from now will you have $315 in your bank account?
There will be $315 in the account after _weeks.
Answers
315 = 80 + (25 + 9)w
315 = 80 + 34w
Subtract 80 from both sides
235 = 34w
Divide both sides by 34
w = 6.9117
