Answer:

2A/r^2 = pi

Step-by-step explanation:

A=1/2πr^2

multiply each side by2

2A = 2*1/2 pi r^2

2A = pi*r^2

divide each side by r^2

2A/r^2 = pi r^2/r^2

2A/r^2 = pi

Answer:

59.5

Step-by-step explanation:

1st tree to shadow ratio: 17:10

Plug the numbers in to get x:35

Need help asap pls :)
pogonyaev

Answer:

See explanation below.

Step-by-step explanation:

First I'm going to find angle 2. Angle two plus 55 is equal to 115. 180-115=65. 65-55=10 Angle 2 = 10

Next, we can find angle 3. 55+10=65. 180-65=115. Angle 3 = 115

Angle 2 is equal to angle 5, angle 3 is equal to angle 6, and angle 4 is equal to 55.

Angle 5 = 10

Angle 4 = 55

Angle 6 = 115

Now we can find angle 8. 180-115=65. Angle 8 = 65

Angle 11 = 65

Angle 12 = 115

10+115=125 Angle 10 = 125

180-125 = 55 Angle 9 = 55

Angle 14 = 55

Angle 13 = 125

What is the range of the function shown in the graph?<br>​
Vika [28.1K]

Answer:

y ≥ 2

Step-by-step explanation:

Range is the y-axis, so we have to look at the graph to find what numbers the line hits.

The line starts at y = 2 and goes up forever (the arrow indicates this), so that means that this line hits all y-values above 2.

Therefore the range is any y-value 2 or higher, so the answer is y ≥ 2.

Find the slope Y=5x+12
NikAS [45]

Answer: The slope = 5.

Step-by-step explanation:

The equation of a line in the slope -intercept form is given by :-

y=mx+c

,where  m= slope , c= y-intercept.

The slope of a line represents the rate of change of y with respect to x.

Given: Equation of line : Y= 5x+12

Here Slope (m)=5

Hence, the slope = 5.
