If C=2pi times r, then r=C divided by 2pi, just use your calculator, punch in 53.4 ÷ 2 ÷3.14, the answer should be 8.5
Answer:
ITS PROBABLY TO LATE TO HELP BUT ITS 4-6 MINUTESSSSS
Step-by-step explanation:
Hello!
The x intercept is when the y value is 0
Put 0 in for y to get the x-intercepts
------------------------------------------------------------------------------------------------------
Part A
3x + 2y = 7
Put 0 in for y
3x + 2(0) = 7
Simplify
3x = 7
Divide both sides by 3
x = 2.333...
The x-intercept is at the point (2.333, 0)
------------------------------------------------------------------------------------------------------
Part B
2x + 3y = 7
Put 0 in for y
2x + 3(0) = 7
Simplify
2x = 7
Divide both sides by 2
x = 3.5
The x-intercept is at the point (3.5, 0)
------------------------------------------------------------------------------------------------------
Hope this helps!
i. Let t be the line tangent at point J. We know that a tangent line at a point on a circle, is perpendicular to the diameter comprising that certain point.
So t is perpendicular to JL
let l be the tangent line through L. Then l is perpendicular to JL
ii. So t and l are 2 different lines, both perpendicular to line JL.
2 lines perpendicular to a third line, are parallel to each other, so the tangents t and l are parallel to each other.
Remark. Draw a picture to check the steps
Answer:
i x = 0
ii x = 5,9
iii y = 12
iv y = 0
Step-by-step explanation:
0 = 12x²/(x - 5)(x - 9)
0 = 12x²
0 = x²
x = 0
ii vertical asymptotes at x = 5, 9
asymptotes occur as either term (x - 5)(x - 9) approaches zero
iii horizontal asymptote y = 12
function essentially becomes 12(∞²)/∞² = 12(1) as x goes to ±∞
iv y = 0 where x = 0
