For every point on the curve, imagine drawing a vertical line until that vertical line reaches the x axis.

Doing this will essentially shade the x axis number line from x = -4 to x = 2

The graph shows points in which the x coordinate is as small as -4 or as large as 2, or anything in between

Domain: -4 \le x \le 2
Answer: Choice B

note: the domain is the set of allowed inputs or x values

Part 6
Deffense [45]

Answer:

Part 1) The volume of each beam is 1,858.88\ ft^{3}

Part 2) You can fill 26\ beams

Part 3) Yes, the amount of sand left over is 1,669.12\ ft^{3}

Step-by-step explanation:

Part 1) What is the total volume of each beam?

The volume of a cylinder is equal to

V=\pi r^{2} h

we have

h=37\ ft

r=8/2=4\ ft ----> the radius is half the diameter

assume

\pi=3.14

substitute the values

V=(3.14)(4)^{2} (37)

V=1,858.88\ ft^{3}

Part 2) How many beams can you fill with this sand?

we know that

You are given a container with a 50,000 sq ft of sand for your beams

<em>Note</em> Is a 50,000 cubic foot  of sand instead of 50,000 sq ft of sand

Divide the total volume of sand by the volume of each beam to obtain the number of beams

50,000/1,858.88=26.9\ beams

Round down

26.9=26\ beams

Part 3) Will you have any sand left over? If so how much?

yes

50,000-26(1,858.88)=1,669.12\ ft^{3}

Prove the identity of tan(pi - x) = - tan x
liq [111]

Two ways:

Step-by-step explanation:

1. First way. Using the trig unit circle.

tan (pi - x) = - tan x

2. Second way. Apply the identity:

tan(a-b)=tan a- tan b/ 1 - tan a×tan b

tan (π - x)= tan π - tanx/1 - tan(π)×tanx

Since tan (pi) = 0, therefor:

tan(π−x)=−tanx

How do you write 70% as a fraction in simplest form ?
alexdok [17]
70% equals to 70/100 in fraction form.
But, you need to write it in simplest form. so, divide both of them from 10 'cause they both can divide completely by it.
70/100 = 7/10
so, your answer is 7/10
