Set up a proportion:

1.5cm/2.5ft = 7.5cm/x

7.5•2.5=18.75

18.75 / 12.5 = 12.5 feet

Solve the proportion using cross products. Round to the nearest hundredth if necessary. $18.45/m gal = $3.60/7.5gal
sveta [45]
\dfrac{\$18.45}{n \text { gallon}}  =  \dfrac{\$3.60}{7.5 \text { gallon}}

Cross multiply
n \times \  3.60 = 7.5 \times \  18.45

Combine like terms
3.60n = 138.375

Find n
n = 138.375\div 360

Answer
n = 0.38 \text { (nearest hundredth)}

If f x equals x -3 + g x equals 1 - x 2 - 9 find ( f og) (x and give any restrictions on its domain
evablogger [386]
\begin{gathered} f(x)=x-3 \\ g(x)=\frac{1}{x^2-9} \\ (\text{fog)(x)}=\frac{1}{x^2-9}-3 \end{gathered}

the denominator cannot be zero, because the division by zero is not defined, therefore:

\begin{gathered} x^2-9=0 \\ \text{Solving for x:} \\ x^2=9 \\ \sqrt[]{x^2}=\sqrt[]{9} \\ x=\pm3 \end{gathered}

Therefore the domain of (f o g)(x) is:

D\colon(-\infty,-3)\cup(-3,3)\cup(3,\infty)

Given f’(x), where is f(x) increasing? Where is f(x) concave up?
Levart [38]

Answer:

See explanation below

Step-by-step explanation:

a. f(x) is increasing at (-∞, 1] and [7, ∞) because f'(x) is positive at those intervals.

b. f(x) is concave up at [4, ∞) because the slope of f'(x) or f''(x) is positive.
