Answer:

The ramp must cover a horizontal distance of approximately 19.081 feet.

Step-by-step explanation:

Given the vertical distance (y), measured in feet, and the angle of the wheelchair ramp (\theta), measured in sexagesimal degrees. The horizontal distance needed for the ramp (x), measured in feet, is estimated by the following trigonometrical expression:

x = \frac{y}{\tan \theta} (1)

If we know that y = 1\,ft and \theta = 3^{\circ}, then the horizontal distance covered by this ramp is:

x = \frac{1\,ft}{\tan 3^{\circ}}

x \approx 19.081\,ft

The ramp must cover a horizontal distance of approximately 19.081 feet.

Answer:

  • a. -7
  • b. -20
  • c. 7

Step-by-step explanation:

  • a. -9+2, in this case, it is -7 because you take the bigger number and subtract it by the lower number. If the bigger number is negative your answer will be negative, if the bigger number is positive it will be positive it is just really a basic subtraction problem just add the sign.
  • b. In multiplication +++=+ ++-=- and a -+-=+ do your problem without thinking about the signs and then add the signs with the formula I showed you.
  • c. ---=+

Hope this helps :)!

Answer:

5 - x

Step-by-step explanation:

Given:

f(x)=25-x^2

g(x)=x+5

\begin{aligned}\left(\dfrac{f}{g}\right)(x) & = \dfrac{f(x)}{g(x)}\\\\ & = \dfrac{25-x^2}{x+5}\\\\& = \dfrac{(5-x)(5+x)}{(x+5)}\\\\& = \dfrac{(5-x)(x+5)}{(x+5)}\\\\& = 5-x\end{aligned}

Evaluate y5 + x(-7)<br> When x = 2, y = -5
Ymorist [56]

Answer:

45

Step-by-step explanation:

OK, first we turn the variables into into the actual values:

The equation will look like this:

(2)5 + (-5)(-7)

Now its easier to solve!  Lets solve (2)5!

2 * 5 = 10

The equation looks like:

10 + (-5)(-7)  

We will also solve (-5)(-7). Remember that a negative number times a negative number is positive!

-5 * -7 = 35

Lets finish the rest:

10 + 35 = 45.          

Hope this is correct and have a nice day!
