Answer:

$57.2\ ft$

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

In this problem

The tangent of angle of 5 degrees is equal to the quotient of "rise over run"

Let

y ----> the rise of the ramp

x ----> the run of the ramp

$tan(5^o)=\frac{y}{x}$

we have

$y=5\ ft$

substitute and solve for x

$tan(5^o)=\frac{5}{x}$

$x=\frac{5}{tan(5^o)}$

$x=57.2\ ft$

Find the area of a circle with radius of 7

zubka84 [21]

Answer:

-The area of a circle:

$A \approx 153.938$

$A \approx 153.94$ (Rounded to nearest hundredth if needed)

Step-by-step explanation:

-Use the formula to find the area of a circle:

$A = \pi r^2$

-After you have the formula set up, use the radius for the formula:

$A = \pi 7^2$

-Then, you solve the formula:

$A = \pi \times 7^2$

$A = \pi \times 49$

$A = 49\pi \approx 153.938$

-Round up to the nearest hundredth (if needed):

$A \approx 153.94$

Write an equation for a circle with a diameter that has end points at (-4,-1) and (-8,-9) round to the nearest tenth if necessar

Mazyrski [523]

1) distance formula; d = √(x2-x1)² +(y2-y1)² . d= √(-4-8)² +(-3-7)² = > d= 2√61

diameter = 2*radius => 2√61 =2r => r =√61 => r² =61

midpoint of the diameter is:

Xm= -4-8 /2 -6 => -6
Ym = -1-9 /2 -5 => -5 center of the cirlce is at (-6,-5)

general equation of a circle: (x-x1)² +(y-y1)² =r² with (x1,y1) being the center of the circle.

equation: (x+6)+(y+5)=61
