Okay, this is C. This is because since he has already driven 3.5miles so far, we already have that and we add it cause we have already driven that. Then, it says 100 miles for every TWO hours. For x, we need to find how many miles we drive in ONE hour. So: 100/2 miles = 2/2 hours: 50 miles = 1 hr.

Find f(1) if f(x)=5^x

dolphi86 [110]

Answer:

The value of function for x = 1 , y = 5 i.e f(1) is 5

Step-by-step explanation:

Given as :

f(x) = $5^{x}$

Now from the function the value of y depend on the value of x

So , for x = 1

I.e f(1) = $5^{1}$

Or, f(1) = 5

Hence The value of function for x = 1 , y = 5 i.e f(1) is 5 Answer

Martin throws a ball straight up in the air. the equation h(t) = -16t^2 + 40t + 5 gives the height of the ball, in feet, t secon

Lisa [10]

Answer:

2.62 seconds

Step-by-step explanation:

Let

t ----> the time in seconds

h(t) ----> he height of the ball, in feet

we have

$h(t)=-16t^2+40t+5$

we know that

When the ball hits the ground, the height is equal to zero

$-16t^2+40t+5=0$

The formula to solve a quadratic equation of the form

$at^{2} +bt+c=0$

is equal to

$t=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-16t^2+40t+5=0$

$a=-16\\b=40\\c=5$

substitute in the formula

$t=\frac{-40\pm\sqrt{40^{2}-4(-16)(5)}} {2(-16)}$

$t=\frac{-40\pm\sqrt{1,920}} {-32}$

$t=\frac{-40+\sqrt{1,920}} {-32}=-0.12\ sec$

$t=\frac{-40-\sqrt{1,920}} {-32}=2.62\ sec$

therefore

The solution is t=2.62 seconds

Byron’s income last year was $61,700. He made $48,000 at his plumbing job and had income from an apartment that he rented out. I

Total income minus income from plumbing gives us income from rent. Divide that by 12 to give us the monthly income from rent.

61700-4800 = 13700

13700/12 = 1,141.67 a month in rent.
