Answer:

ur hyp would be 9m(cuz that's the length of the pole)

ur opp would be 7.5m

draw a right angle triangle(the 90 degrees on the left side)

the angle u need will be on the bottom left of the triangle.

now u need to use SOH cuz u got hyp and opp.

sin theta =opp/hyp

then u need to do:

sin‐1 opp/adj to find the angle

round to the nearest whole.

I'm not sure if this helped but yeah.

Answer:

the period of this graph is 2 $\pi$

Step-by-step explanation:

The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.

Let's look at the peaks (maximums).

One is at x = 0 and the next is at x = 2 $\pi$

2 $\pi$ - 0 = 2 $\pi$

Therefore, the period of this graph is 2 $\pi$

Answer:

AJ picks 252 pounds

Step-by-step explanation:

Lets define the following letters for each name:

A is AJ

B is Blaze

L is Laurence

J is Jack

Now we will analyze the phrases one by one:

Blaze picks three times as many as Laurence means:

$B = 3 * L$

Jack picks twice as many as Blaze.

$J = 2 * B$ , ans using the previous one lets substitute B with 3 * L

$J = 2 * B = 2 * (3 * L)$

$J = 6 * L$

Aj picks three times as many as Laurence.

$A = 3 * L$

The total weight of the oranges is 1092 pounds.

$A + B + J + L = 1092$

We replace A, B & J in the last equation, with the previous results:

$A + B + J + L = 1092$

$(3*L) + (3*L) + (6*L) + L = 1092$ , grouping using L as common factor:

$(3+3+6+1) * L = 1092$

$13 * L = 1092$ , then isolating L:

$L = 1092 / 13$

$L = 84$ pounds (for Laurence)

Finally replacing L in the previous equations:

$A = 3 * L = 3 * 84 = 252$ pounds (for Aj)

$B = 3 * L = 3 * 84 = 252$ pounds (for Blaze)

$J = 6 * L = 6 * 84 = 504$ pounds (for Jack)
