Answer:

f(-1)=19

Step-by-step explanation:

<u>Evaluating Functions</u>

Given a function y=f(x), evaluate the function for x=a means substituting the variable for the given value.

We have the function:

f(x)=3x^2+16

Find f(-1):

f(-1)=3(-1)^2+16

f(-1)=3(1)+16

f(-1)=3+16

\boxed{f(-1)=19}

A beekeeper has 65,000 female bees and 700 male bees in one colony. A disease kills % of the female bees and % of the male bees.
Paha777 [63]

Complete Question

A beekeeper has 65,000 female bees and 700 male bees in one colony. A disease kills 25% of the female bees and 14% of the male bees. After the disease hits the colony, the beekeeper decides to sell LaTeX: \frac{1}{2} 1 /2 of the remaining female bees to a friend.

How many total bees are left in the beekeeper’s colony after the disease and sale?

Answer:

24977 bees

Step-by-step explanation:

From the above question:

Number of female bees = 65,000

Number of male bees = 700

A disease kills 25% of the female bees and 14% of the male bees.

Number of female bees killed = 25% × 65,000

= 16,250 bees

Amount of female bees left = 65,000 - 16,250

= 48750 bees

Number of male bees killed = 14% × 700

= 98

Amount of male bees left = 700 - 98

= 602 bees

After the disease hits the colony, the beekeeper decides to sell LaTeX: \frac{1}{2} 1 /2 of the remaining female bees to a friend.

Hence:

1/2 × 48750 bees

= 24375 bees

Total bees are left in the beekeeper’s colony after the disease and sale is calculated as:

24375 female bees + 602 male bees

= 24977 bees

Step-by-step explanation:

\frac{x + 3}{ {x}^{2} + 7x + 12 } . \frac{ {x}^{2}  + x - 12}{3x - 18}  \\  \\  = \frac{x + 3}{ {x}^{2} + 4x + 3x + 12 } . \frac{ {x}^{2}  + 4x - 3x - 12}{3(x - 6)}  \\  \\ = \frac{x + 3}{ {x}(x + 4) + 3(x + 4) } . \frac{ {x}(x + 4) - 3(x  + 4)}{3(x - 6)}  \\  \\ = \frac{ \cancel{(x + 3)}}{ (x + 4)  \cancel{(x + 3)} } . \frac{ (x + 4) (x   - 3)}{3(x - 6)}  \\  \\ = \frac{1}{ \cancel{ (x + 4)}   } . \frac{  \cancel{ (x + 4)} (x   - 3)}{3(x - 6)}  \\  \\    \red{ \bold{= \frac{   (x   - 3)}{3x - 18}  }}\\  \\
