Answer: She donated $9.86.
Step-by-step explanation:
She earns $11.60 per hour.
She donates .
She worked hours.
How much did she donate?
--------------------------------------------------------------
If she earns $11.60 per hour, how much is that in hours?
First, let's convert the mixed number to an improper fraction. You can do this by multiplying the big number times the denominator and adding the numerator; all over the same denominator.
Now divide to obtain a decimal number.
She worked 8.5 hours. Multiply this by 11.60 which is the amount she earns per hour.
8.5*11.60=$98.60
Now to calculate of $98.60, multiply again.
Vertex = (0, 0)
focus = (-2, 0)
p = -2 - 0 = -2
Required equation is (y - k)^2 = 4p(x - h); where (h, k) = (0, 0), the vertex
(y - 0)^2 = 4(-2)(x - 0)
y^2 = -8x
Required equation in standard form is x = -1/8 y^2
The answer of this is 3,6,9,12,15,18,21,24,27,30,33,36,39,...
<span>Given cosA x cos2A x cos4A x cos8A = sin16A/16sinA
RHS
sin16A/16sinA
[2sin8A cos 8A]/16sinA
[cos8A(2sin4A cos4A)]/8sinA
[cos8A cos 4A(2 sin 2A cos 2A)]/4sinA
[cos 8A cos 4A cos 2A(sin2A)]/2 sinA
[cos8A cos 4A cos 2A(2sinA cos A)]/2
sin A
cos A cos 2A cos 4A cos 8A
Hence RHS=LHS</span>
The answer is A!
Sadie is correct because 3(2x+3y) equals 6x+9y
