The highway mileage m in miles per gallon for a compact car is approximated by m(s) = -0.025s^2 + 2.45s - 30, where s is the spe
Over [174]
The maximum mileage per gallon for the compact car is determined by taking the first derivative of the given equation and equate to zero. The differentiated form is m's = -0.05 s + 2.45 = 0; s is equal to 49 seconds. substituting this s, m is equal to 30.025 miles/gallon.

Rewrite the equation y=2|x−3|+5 as two linear functions f and g with restricted domains.
Mama L [17]

Answer:

f(x) = 2+5

g(x) = 2(-(x−3))+5

Step-by-step explanation:

If you remember, an absolute value can have two different answer, a positive and negative answer because the absolute value symbol makes all values in it positive. Example: |-2|=2 and |2|=2

So if  y = 2|x−3|+5

then the two possibilities are

y = 2(x−3)+5    and

y = 2(-)+5

Set one of them equal to f(x) and the other one to g(x)

f(x) = 2(x−3)+5

g(x) = 2(-(x−3))+5

You can also write it as a piecewise function.

y(x)=$\begin{array}{cc}  \{ &     \begin{array}{cc}      -(x-3) & x3    \end{array}\end{array}$

What is the solution set of {x | x < -3} ∩ {x | x > 5}?
solniwko [45]

x <-3 includes the numbers-4, -5, -6..........

x> 5 includes the numbers 6, 7 , 8.....

here we have to find intersection of these two.

By intersection we mean the values of x that occur in both the sets,

here there is no number or value of x that occur in both the sets.

So answer is empty set

IgorC [24]

Answer:

6 3/8

Step-by-step explanation:

Convert the fractions so that the denominators match.

3\frac{3}{4} =3\frac{6}{8}, then 3\frac{6}{8}=\frac{30}{8}

1\frac{1}{8}=\frac{9}{8}

2\frac{1}{2}=\frac{3}{2}, then \frac{3}{2}=\frac{12}{8}

Add up the fractions.

\frac{30}{8}+\frac{9}{8}+\frac{12}{8} =\frac{51}{8} =6\frac{3}{8}
