Find the absolute maximum and minimum values of the function over the indicated​ interval, and indicate the​ x-values at which t
Yakvenalex [24]

Answer:

a. Maximum= 27, minimum= -5

b. Maximum= 19, minimum=-37

Step-by-step explanation:

We have the function f(x)=8x-5. Since the function correspond to a line, then the maximum and minimum values of the function over an interval are in the endpoints of the interval.

Observe that if the line has negative slope then the minimum value is in the right endpoint. If the line has positive slope the minimum value is in the left endpoint of the interval.

The function f(x) has slope m=8. Then

a. the minimum value of f(x) in the interval [0,4] is reach when x=0, and the minimum is f(0)=8*0-5=-5 and the maximum is f(4)=8(4)-5=32-5=27

b. the minimum value of f(x) in the interval [-4,,3] is reach when x=-4, and the minimum is f(-4)=8(-4)-5=-32-5=-37 and the maximum is f(3)=8(3)-5=24-5=19

1 7/10 x 2/3 what is the product
Ludmilka [50]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{1 \frac{2}{15}}}}}}

Step-by-step explanation:

\sf{1 \frac{7}{10}  \times  \frac{2}{3} }

Convert the mixed number into improper fraction

\longrightarrow{ \sf{ \frac{10 \times 1 + 7}{10}  \times  \frac{2}{3}}}

\longrightarrow{ \sf{ \frac{17}{10}  \times  \frac{2}{3}}}

To multiply one fraction by another, multiply the numerators for the numerator, and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term

\longrightarrow{ \sf{ \frac{17 \times 2}{10 \times 3}}}

\longrightarrow{ \sf{ \frac{34}{30}}}

\longrightarrow{ \sf{ \frac{17}{15} }}

Convert the improper fraction into mixed number

\longrightarrow{ \sf{1 \frac{2}{15} }}

Hope I helped!

Best regards! :D
