Answer:

2. The change in expected height for every one additional centimeter of femur length.

Step-by-step explanation:

1. The expected height for someone with a femur length of 65 centimeters.

Doesn't make sense, that would be height value when centimeters = 65.

2. The change in expected height for every one additional centimeter of femur length.

Makes sense, for every increase in one additional centimeter, we can expect the height to be proportional to the slope.

3. The femur length for someone with an expected height of 2.5 centimeters.

Doesn't make sense, the linear relationship relies on the femur length to get the height.

4. The change in expected femur length for every one additional centimeter of height.

Doesn't make sense, again, the linear relationship relies on the femur length.

Temka [501]

Answer:

Nu 4550

Step-by-step explanation:

Commission of 5% only applies to the first 70,000 so

$70,000*\frac{5}{100} = 3500$

That leaves 15,000 left in sales where the 7% commission applies.

$15,000*\frac{7}{100}=1050$

Adding these two together we get a total of

$3500 +1050=Nu4550$

(ar^b)^4=81r^24 where a and b are positive integers. Work out a and b

galina1969 [7]

Answer:

Vales of a =3 and b = 6

Step-by-step explanation:

Given that: $(ar^b)^4 = 81r^{24}$ .....[1] where a and b are positive integers

we can write 81 and 24 as;

$81 = 3 \cdot 3 \cdot 3 \cdot 3 = 3^4$

$24 = 4 \cdot 6$

We have [1] as;

$(ar^b)^4 = 3^4r^{4 \cdot 6}$

Using power rules;

$a^nb^n = (ab)^n$

$a^n = b^n$ which implies a = b

then;

$(ar^b)^4 = (3r^6)^4$

$ar^b = 3r^6$

On comparing both sides we have;

a = 3 and

$r^b = r^6$

⇒ $b = 6$

Therefore, the value of a and b are, 3 and 6
