Answer:

D. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp

Step-by-step explanation:

f(x) = x²- 10x + 25

We can factor this.

What 2 numbers multiply to 25 and add to -10

-5 *-5 = 25

-5+-5 = -10

f(x) =(x-5) (x-5)

Using the zero product property, we know that it will cross the axis at x=5

At 5 seconds f(x) =0.  This means the height is zero at 5 seconds

Using the triangle below, find the ratio please need help answering for a quiz
Murrr4er [49]
<h3>sin22° = 5/4</h3><h3>tan22° = 3/√55</h3>

As we know that , sinA = opposite/hypotenuse & tanA = opposite/adjacent

So here we can find sin22° , because they already given the sides opposite & hypotenuse . And we can't find tann22° because they given the value of opposite but not given the value of adjacent side of the angle 22°

Now finding the adjacent side using

Pythagoras theorem :-

• Hypotenuse² = Base² + Height²

=> 40² = Base² + 15²

=> 1600 - 225 = Base²

=> Base² = 1375

=> Base = √1375

=> Base = 5√55

Now ,

  • tan22° = Opposite/Adjacent = 15/5√55 = 3/√55
  • sin22° = Opposite/hypotenuse = 15/40 = 5/4

Write down and simplify the following algebraic expressions. The sum of −3x+5 and 7−4x is subtracted from 5x+17.
andriy [413]
Sum of the first two is:
-3x+5+7-4x = -7x+12
That subtracted from 5x+17:
5x+17-(-7x+12) = 12x+5

Find the difference quotient of the exponential function, f(x) = e^x
Orlov [11]

Answer:

Step-by-step explanation:

The difference quotient in general looks like

\frac{f(x+h)-f(x)}{h}   Sometimes the symbol "delta x"  \Delta x   is used instead of h.

For the exponential function, the difference quotient is

\frac{e^{x+h}-e^x}{h}
