Answer:
t = 13
Step-by-step explanation:
3 months ------ 4500
6 months ------ x
3/6 = 4500/x
cross multiplation:
3x =27000
x = 9000,or we should have just doubled the wages, since the time doubled
3 months ------ 4500
5 months ------ y
3/5 = 4500/y
3y = 22500
y = 7500
3 months ------- 4500
t months -------- 19500
3/t = 4500/19500 = 3/13
3t = 39
t = 13
The answer is B. Since you know the lengths of both legs of the triangle, you can use the Pythagorean Theorem to solve. The Pythagorean Theorem says "a squared plus b squared equals c squared. The square root of c is the length of the hypotenuse." Since there is no answer that says 19.799 (This is the approximate answer), then the answer is B.
We know that
the equation of a circle is
(x-h)²+(y-k)²=r²
where
(h,k)-----> is the center
r--------> is the radius
is the center is the point (0,0) and radius r=20
then
(h,k) is (0,0)
(x-0)²+(y-0)²=20²---------> (x)²+(y)²=400
the answer is
the option D.) x2 + y2 = 400
Answer:
y = 1/3x + 6
Step-by-step explanation:
Rearrange equation to get y by itself.
3x + y = -1
y = -3x - 1
Perpendicular = opposite reciprocal. This means that the slope = 1/3
Convert to point-slope form: y - y1 = m (x - x1)
y - 5 = 1/3 (x - (-3))
y - 5 = 1/3 (x + 3)
y - 5 = 1/3x + 1
y = 1/3x + 6
Answer:
g(f(x)) = 3x^2 + 6x -11
Step-by-step explanation:
g(f(x)) = 3(x^2 + 2x - 4) + 1
= 3x^2 + 6x -12 + 1
= 3x^2 + 6x -11
