F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
Answer: D ) 24
64 is the number of a perfect cube
By dropping a perpendicular from the top of the isosceles triangle to the base and using the Pythagorean Theorem we quickly determine that the height of the triangle is 4.
Therefore the area of the isosceles triangle is
6•4/2=12
However, we can split the isosceles triangle into three separate triangles indicated by the red lines in the diagram below. Because the radius always meets a tangent at a right angle the area of each triangle will be the length of the side multiplied by the radius of the circle. So the total area of the isosceles triangle is given by
6r/2+2•5r/2=8r=12
8r=12
r=12/8
r=3/2
Answer:
-17x - -43z + 20
Step-by-step explanation:
-17x - -43z + 20
First, figure out the new salary. To do this, multiply 15.50 and 0.18. This is 2.79. Add this to 15.50.
15.50 + 2.79=18.29
Therefore, $18.29 is her hourly pay.
To find how much money she earns in 10 hours, multiply this pay per hour (18.29) times the hours worked (10).
18.29 x 10
182.9
This means that Paige earns $182.90 for working 10 hours.
