What is the average rate of change of the function over the interval x = 0 to x = 8?
salantis [7]
Ans:  The average rate of change of function = \frac{1}{102} (in fraction)

Explanation:
The average rate of change of function  = \frac{f(b) - f(a)}{b - a}

Where
b = 8 (x's upper bound)
a = 0 (x's lower bound)

f(b) = f(8) =  \frac{2*8-2}{5*8-6} =  \frac{7}{17} \\ f(a) = f(0) =  \frac{2*0-2}{5*0-6} =  \frac{1}{3} \\  \frac{f(b)  - f(a)}{b-a} =  \frac{ \frac{7}{17} -  \frac{1}{3}}{8} =  \frac{1}{102}

Hence the average rate of change of function = \frac{1}{102} (in fraction)

bobby pays a $25 membership free to join YMCA gym. This gym allows members to attend any exercise class for only $4. The linear
blagie [28]

Answer:

Step-by-step explanation:

T = 4c + 25....where c = # of classes and T = total cost

2 classes...so sub in 2 for c and solve for T

T = 4(2) + 25

T = 8 + 25

T = 33 <==== with 2 classes ,its $ 33

4 classes....so sub in 4 for c and solve for T

T = 4(4) + 25

T = 16 + 25

T = 41 <==== with 4 classes, its $ 41

8 classes....sub in 8 for c

T = 4(8) + 25

T = 32 + 25

T = $ 57 <==== with 8 classes, its $ 57

10 classes...sub in 10 for c

T = 4(10) + 25

T = 40 + 25

T = 65 <===== with 10 classes, its $ 65

Tamara says she used the GCF to factor the expression 21x + 56xy as 7(3x + 8xy). Is she correct? Explain.
coldgirl [10]

Answer:

Tamara incorrectly factored the whole expression.

Step-by-step explanation:

Note that

•21x=3·7·x;

•56xy=2·2·2·7·x·y.

Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.

Thus,

21x+56xy=7x(3+8y).

Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.
