(g\cdot f)(x)=g(x)\cdot f(x)\\\\f(x)=|x+2|,\ g(x)=-x^2\\\\(g\cdot f)(3)=g(3)\cdot f(3)\\\\\text{Put the value of x = 3 to the equations of a functions:}\\\\f(3)=|3+2|=|5|=5\\\\g(3)=-3^2=-9\\\\(g\cdot f)(3)=(-9)(5)=-45\\\\Answer:\ \boxed{-45}

What is the surface area of this composite figure?
andrew-mc [135]

Answer:

1260 inches squared

Step-by-step explanation:

Bottom: 24*6=144

Bottom front: 24*12=288

Bottom back: 24*12=288

Left side: 6*2=72

Right side: 6*12=72

Left top: 6*15=90

Right top: 6*15=90

Top front: (24*9)/2=216/2=108

Top back: (24*9)/2=216/2=108

144+288+288+72+72+90+90+108+108=1260

Ksju [112]

Complete question :

A population of 30 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain 600 deer. The population would grow by 30 percent per year

how many after one year

how many after two years

Answer:

39 deers

51 deers

Step-by-step explanation:

The question can be expressed using the compounding rate formula:

A = P(1+r)^t

A = final population ; P = initial population ; rate, r = 30% = 0.3 ; t = time

After 1 year, t = 1

A = 30(1 + 0.3)^1

A = 30(1.3)^1

A = 39 deers

B.)

After 1 year, t = 2

A = 30(1 + 0.3)^2

A = 30(1.3)^2

A = 50.7

A = 51 deers approximately

Write an equation for a line perpendicular to y = 2 x + 4 and passing through the point ( − 2 , 3 ) . Express your answer in slo
aleksklad [387]

Answer:

y = -1/2x + 2

Step-by-step explanation:

A perpendicular line will have a opposite reciprocal slope.

Since the line's slope is 2, the perpendicular line will have a slope of -1/2

Plug in the slope and given point into y = mx + b, and solve for b

y = mx + b

3 = -1/2(-2) + b

3 = 1 + b

2 = b

Plug in the slope and b into y = mx + b

y = -1/2x + 2

So, the equation is y = -1/2x + 2

Find the total cost of a $32 Uber ride with a 15% tip. Round to the nearest cent when necessary
Marianna [84]

$36.80

Explanation:

Cost of Uber ride = $32

Tip = 15%

\begin{gathered} \text{Tip Amount = }15\text{ \% }\times\text{ \$32} \\ \text{Tip Amount = 0.15 }\times\text{ \$32} \\ \text{Tip Amount = \$4.8} \end{gathered}\begin{gathered} \text{Total cost = cost of Uber ride + tip amount} \\ \text{Total cost = }32\text{ + \$4.8} \\ \text{Total cost = }36.8 \\  \\ \text{Total cost is \$36.80} \end{gathered}
