Answer:

B. f(-1)=6

C. The domain of f(x) is the set {-2.-1,0,1,2,3,4,5,6}

Step-by-step explanation:

To find f(5) from the table means, the y-value that corresponds to x=5.

This value is 12.

This implies that:

f(5)=12

Also the y-value that corresponds to -1 is 6.

Hence f(-1)=6

The domain of f(x) are the set of all the x-values.

The domain is : {-2.-1,0,1,2,3,4,5,6}

The range for f(x) is the set of all the corresponding y-values.

From the table, the range is: {5,6,7,8,9,10,11,12,13}

Solve for x the rest of the question is in the png

zvonat [6]

Answer:

33.18

Step-by-step explanation:

Use law of sines.

x / sin(65°) = 21 / sin(35°)

x = 21 sin(65°) / sin(35°)

x ≈ 33.18

graph 1 graph 2 graph 3 graph 4 Which graph represents the function f(x) = x2 + 3x + 2? A. graph 1 B. graph 2 C. graph 3 D. grap

stiv31 [10]

Answer:

See attachment

Step-by-step explanation:

To see clearly the graph that represents

$f(x) = {x}^{2} + 3x + 2$

we rewrite in vertex form to get;

$f(x) = (x + \frac{3}{2})^{2} - \frac{1}{4}$

This is a vertical parabola with vertex at (-1.5,-0.25) and opens upwards.

The required graph is shown in the attachment.

when a spherical balloon is filled with air, it has a radius of 3 inches. what is the estimate for the volume of air in the ball

Crazy boy [7]

The volume of a sphere is given by the equation $V=\frac{4}{3} \pi r^{3}$ , where V is the volume and r is the radius.

To answer this question, simply plug the correct values into the equation:

$V=\frac{4}{3} \pi 3^{3} \\V=4.1888(27)\\V=113.0976$

The volume of the air in the balloon is about 113.0976 in3.

Hope this helps!!
