Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:
As you can see, x increases in steps of 1 units. So let's check the difference in y:
So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:
Then:
Finally, the equation of the line is:
To find the measure of the s angle que are going use the cosine law because we know all the sides of the triangule:
s² = r² + t² - 2*r*t * cos(S)
Then solve the equation
s² -r² - t² = -2*r*t * cos(S)
arccos ((s² -r² - t² /-2*r*t)) = S
arccos (((250)² -(850 cm)²-(940 cm)² /(-2* 850 cm*940 cm) = S
14.9 = S
round to the nearest 10th of a degree
15º = S
Answer: He owes Beth and his mom $125
Step-by-step explanation:
Hey there! :)
The formula for finding area of circles is: π · r²
<em>Remember that radius is half the diameter. To find radius when the diameter is given, divide by 2</em>
d = 26
26 ÷ 2 = 13
_____________________________________________________________
π · r²
r = 13
13² = 13 × 13 = 169
169 × 3.14 = 530.66 = 530.7
The area of the swimming pool is 530.7 ft²
Hope this helps :)
