Answer:

Sam's total is $29.46

Step-by-step explanation:

$9.20 multiplied by the quantity of the DVDs (4), is $36.80.

If you subtract 25% of that, it brings your amount to $27.60.

Add 6.75% for the sales tax, which makes the total amount to $29.46

he graph represents function 1, and the equation represents function 2: A coordinate plane graph is shown. A horizontal line is
Reika [66]

Answer:

The answer is 2

Step-by-step explanation:

Rate of change of function is given by :

\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}

For function y = 6,

rate of change =  

=\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}\\=\frac{6-6}{x_{2}-x_{1}}\\=0

because the function is independent of x.

For function y = 2·x + 7,

rate of change =

=\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}\\=\frac{2\cdot x_{2}+7-2\cdot x_{1}-7}{x_{2}-x_{1}}\\=\frac{2\cdot x_{2}-2\cdot x_{1}}{x_{2}-x_{1}}\\=\frac{2\cdot (x_{2}-x_{1})}{x_{2}-x_{1}}\\=2

So, the rate of change of 2 is greater than rate of change of function 1 by 2 - 0 = 2.

A young sumo wrestler goes on a special diet to gain weight.
Ilia_Sergeevich [38]

Answer:

10.8 kg

Step-by-step explanation:

w = 80 + 5.4t

At time 0, when he starts the diet, his initial weight is

w = 80 + 5.4(0)

w = 80

80 kg.

After 2 months, t = 2. His weight is

w = 80 + 5.4t

w = 80 + 5.4(2)

w = 80 + 10.8

w = 90.8

90.8 kg.

His gain in 2 months was 90.8 kg - 80 kg = 10.8 kg

Answer: 10.8 kg
