Answer:
6. Multiply 2 by 6
7. 71 + 9(8) = 71 + 72 = 143
8. 52 + 3(4) = 12 + 52 = 64
9. 19.25 + 2.75(7) = 19.25 + 19.25 = 38.50
10. 2(0.6)^2 + 4(0.6)(5) = 0.72 + 12 = 12.72
Srry if they r wrong
Answer:
A: f(x)=10cos(2π/5 x)+10
Step-by-step explanation:
The coefficient of x in the cosine argument of the function will be 2π/period. Since the period is 5, the coefficient is 2π/5. This observation eliminates choices B and C.
The description "not a reflection of the parent function over the x-axis" means the multiplier of the cosine function is not negative, eliminating choice D.
The remaining choice A matches the description.
Answer:
There are 16 track events and 6 field events
You said -x + 8 > 6
Subtract 8 from each side: -x > -2
Add 'x' to each side: 0 > -2 + x
Add 2 to each side: 2 > x
Now, test the choices:
A). Can 'x' be 4 ?
No. 2 is not greater than 4 .
B). Can 'x' be 1 ?
Yes. 2 is greater than 1 .
C). Can 'x' be 2 ?
No. 2 is not greater than 2 .
D). Can 'x' be 15 ?
No. 2 is not greater than 15 .
