Given the piecewise function f(x) is defined below
 $f(x)= \left \{ {{x^2+1; \ \ \ -4 \leq x \ \textless \ 1} \atop {-x^2; \ \ \ 1 \leq x\ \textless \ 2}} \atop {3x; \ \ \ x \geq 2} \right.$

In the piecewise function, we use the top function, when x has a value from -4 to 1, 1 not included. We use the middle function when x has a value from 1 to 2, 2 not included. And we use the bottom function when x has a value of 2 and above.

Therefore, to find f(1), we make use of the middle function.
$f(1) = -(1)^2=-1$

Aneli [31]

Given:

howler monkey: {15, 16, 17, 17, 17, 17, 18, 19}
spider monkey: {12, 13, 13, 14, 14, 14, 16, 16}

The mean of the first set (howler monkey) = (15 + 16 + 17 + 17 + 17 +17 + 18 + 19)/ 8
The sum of all weights is divided by the number of monkeys weighed (n = 8)

mean = 17

Do the same for the second set (spider monkey) = 12+ 13 + 13+ 14 + 14+ 14 +14 +16 + 16 / 8

mean = 15.75

The ratio of the two is 17:15.75 or 1.08 is to 1.

Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k. A) 2 B) 3 C) 4 D) 5 IF YOU ANSWER IN 5 MINUTES I WILL

andreev551 [17]

Ans k = 4

Step-by-step explanation:

Here g(x) = $\frac{-1}{3}x + 1$ and

f(x) = $\frac{-1}{3} x -3$

Now, g(x) = f(x) + k

or, $\frac{-1}{3}x + 1$ = $\frac{-1}{3} x -3 + k$

or, 1 + 3 = k

So, k = 4 Answer.

Find the surface area of the regular hexagonal prism. Round your answer to the nearest hundredth.

natka813 [3]

A single rectangle has the area of (11 mm)(8 mm) = 88 mm²
So the lateral areas which are the total number of rectangles will be 6*(88 mm²) = 528 mm²
Just recall the formula of the regular polygon, given the side of that polygon.
This hexagon has the area of (1/4)*(6)*(8²)*cot(180°/6) = 166.28 mm²
There are two bases; so 2*(166.28 mm²) = 332.55 mm²

Hence, the surface area is lateral areas + base areas:
528 mm² + 332.55 mm² = 860.55 mm² (ANSWER: d)
