The interest would be $17,878
Use:
P(I)(N)
Where P = 55,000
I = 0.065 *found by dividing 6.5/100*
and N = 5
55000(.065)(5) = 17878
Answer:
90
Step-by-step explanation:
*One half of two fifths of x.
No, he will not cover at least 8 miles because 120 yards times the 30 times he runs the circle equals 3,600 yards which converts to about 2 miles
7/10 x 57 should be the correct one.
That funky circle in the middle is the composition of the function. It asks you to take a function as an input and to yield an output that's another function. It's one of the five function operations, along with adding, subtracting, multiplying, and dividing.
When you compose, you might find the notation w(u(x)) easier to understand. It's saying evaluate u then evaluate w.
For our functions, the compositions are:
u(w(x)) = u(2x²) = -(2x²) - 2 = -2x² - 2
w(u(x)) = w(-x - 2) = 2(-x - 2)² = 2(x² + 4x + 4) = =2x²+ 8x +8
Now we evaluate each composition at 4.
u(w(4)) = -2(4²) - 2 = -2(16) - 2 = -32 -2 = -34
w(u(4)) = -2(2²) +8(2) + 8 = -2(4) + 16 + 8 = -8 + 16 + 8 = 16.
Thus, u(w(4)) = -34 and w(u(4)) = 16.
