3. tan(α) = height/distance
distance = height/tan(α)
distance = (648 m)/tan(13°) ≈ 1399.5 m
6. when y = |x| is translated 6 units down, 6 is subtracted from the y-value:
.. y = |x| -6
10. In point-slope form, the line through point (h, k) with slope m is
.. y -k = m(x -h)
For (h, k) = (10, -9) and m = -2, you have
.. y +9 = -2(x -10)
The answer to this question is sqrt(2)/2. Invoke the unit circle to derive this expression, or use special triangles and reference triangles.
Hello,
(6x+13)+(3x-4)=180
9x+9=180
9x=171
x=19
angle QRS measures 3x-4=3*19-4=53(°)
Answer:
<u>417.4ft^2</u>
Step-by-step explanation:
Surface area of a cone = πr(r+√r²+h²)
r is the radius
h is the height
Substitute
Surface area of a cone = π(5)(5+√5²+21²)
Surface area of a cone = πr(5+√25+441)
Surface area of a cone = π(5)(5+21.59)
Surface area of a cone = 3.14*5*26.59
Surface area of a cone <u>= 417.4ft^2</u>
<u>Hence the surface area of the cone is 417.4ft^2</u>
