Answer:
- D. The experimental data does not support Sally’s hypothesis.
Step-by-step explanation:
<u>Sally's hypothesis can be shown as:</u>
- 8c = 1p, where c- coil, p- paper clip
<u>From the data in the table we can see that:</u>
- 8c = 2p ⇒ 4c = 1p
- 16c = 4p ⇒ 4c = 1p
- 24c = 6p ⇒ 4c = 1p
As we see there is a difference, Sally can pick up one paper clip for each 4 coils.
Correct answer choice is D.
Answer:
z+7-z+9
Step-by-step explanation:
Step-by-step explanation:
x^3 is a perfect cube, 8 is a perfect cube, so we use difference of cubes.
Cube root of x^3 is x.
Cube root of 8 is 2
So
a=x
b= 2.
Set these equations equal to zero
If we do the discriminant, we get a negative answer so we would have two imaginary solutions,
Thus the only real root is 2.
If you want imaginary solutions, apply the quadratic formula.
and
Formula: SA = (2 × π(pie) × radius × height) + (2 × π(pie) × radius square.)
So the equation will be SA=( 2 × 3.14 × 2 × 4) + ( 2 × 3.14 × 2²)
Then, we will get ↓ ↓
SA= 50.24 + 25.12
<u>SA = 75.36 in</u><u>²</u>
Answer:
Step-by-step explanation:
-16-16v - v = 10v + 4
Add 16 to both sides and combine like terms giving you
15v = 10v + 20
Subtract 10v from both sides
5v= 20
Divide by 5
V=4
