Answer:

The horizontal distance is 49.5 feet

Step-by-step explanation:

The ratio is a horizontal distance of 3 feet for every 1 foot drops.

So for a 16.5 foot drop. the horizontal distance = 16.5 *3 = 49.5 feet

Answer:

49.5'

Step-by-step explanation:

horizontal / vertical drop = 3' / 1'

Answer:

divide the figure into two parts.

area of triangle = 1/2×base×height

area of triangle = 1/2×3×3

area pf triangle = 4.5 units²

area of square = side²

area of square = 3²

area of square = 9unit²

If 3 is added to twice a number, the result is 17. Find the number

Crank

Answer:

Step-by-step explanation:

The text of this expression is:

"If 3 is added to twice a number, the result is 17. Find the number"

Let's call $x$ the number we want to find.

Twice the number is equal to

$2x$

So, if we add 3 to 2x, we get

$3+2x$

And we know that this is equal to 17:

$3+2x=17$

Now we can solve the equation to find x: first, we subtract 3 from both sides

$3+2x-3=17-3\\2x=14$

Now we divide both sides by 2:

$\frac{2x}{2}=\frac{14}{2}\\x=7$

Consider the following. y = x2 y = 20 − x Maple Generated Plot (a) Find the area of the region by integrating with respect to x.

Hunter-Best [27]

Answer:

area = 121.5

Step-by-step explanation:

See below for a plot and the integral. We assume you are interested in the entire bounded region.

$\displaystyle\text{area}=\int_{-5}^4{(20-x-x^2)}\,dx=\left.20x-\dfrac{x^2}{2}-\dfrac{x^3}{3}\right|_{-5}^4\\\\=20(4-(-5))-\dfrac{4^2-(-5)^2}{2}-\dfrac{4^3-(-5)^3}{3}\\\\=180+\dfrac{9}{2}-63=121.5$
