The answer is X = 12.
This is how to get that answer: the formula for the intersecting secant and tangent outside the circle is a^2 = b(b+c) If you use the numbers in the pic you will get x^2 = 9(9+7) so the number after the equal sign will be 144, so x^2 = 144. To undo the square youre gonna use the square root on both sides, so you have X = 12.
The area would be approximately 153.94.
The area of a circle is pie multiplied by r^2.
So you have the radius, which is r. Plug in r. Technically you have two numbers because pie equals approximately 3.14.
A=3.14(7)^2
Answer:
17
Step-by-step explanation:
Let the larger number be represented by x
Let the smaller number be represented by y
from the question, the next equations can be gotten :
x - y = 9 equation 1
x = 1 + 2y equation 2
Substitute for x in equation 1
1 + 2y - y = 9
1 + y = 9
Collect like terms
y = 9 - 1
y = 8
Substitute for y in equation 1 and solve for x (the larger number)
x - 8 = 9
x = 9 + 8
x = 17
the answer is 120 bc 140 is adjacent to it and 140-20 = 120
Answer:
m = 5,520.619
Step-by-step explanation:
The given equation is :
y=5,520.619x-1,091.393 ....(1)
The general form of equation is given by :
y = mx +c ...(2)
Where
m is slope of line
c is y-intercept
Comparing equation (1) and (2), we get :
Slope, m = 5,520.619
Hence, the slope of the given line is 5,520.619.
