Answer: b = 40

sin B = \frac{40}{41}

cos B = \frac{9}{41}

tg B = \frac{40}{9}

sec B = \frac{41}{9}

csc B = \frac{41}{40}

cot B = \frac{9}{40}

Step-by-step explanation: If the right angle is at C, then the hypothenuse is side c = 41.

Using Pythagorean Theorem:

hypotenuse² = side² + side²

41² = 9² + b²

b = \sqrt{1681 - 81}

b = 40

The side b length is <u>40</u>,

The trigonometric functions of a right triangle are:

1) Sine = \frac{opposite side}{hypotenuse}

sin (B) = \frac{b}{c}

Sin(B) = \frac{40}{41}

2) Cosine = \frac{adjacent side}{hypotenuse}

cos (B) = \frac{a}{c}

cos (B) = \frac{9}{41}

3) Tangent = \frac{opposite}{adjacent}

tg (B) = \frac{b}{a}

tg (B) = \frac{40}{9}

4) Sec = \frac{1}{cos}

sec(B) = \frac{c}{a}

sec(B) = \frac{41}{9}

5) Cosecant = \frac{1}{sin}

csc(B) = \frac{c}{b}

csc(B) = \frac{41}{40}

6) Cotangent = \frac{1}{tg}

cot(B) = \frac{a}{b}

cot(B) = \frac{9}{40}

Answer:

A

Step-by-step explanation:

Find the mean:

Day 1: 2

Day 2: 1

Day 3: 4

Day 4: 5

Day 5: 0

Day 6: 7

Mean = \frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17

This does not exceed a daily mean of 3.5 hours which was set by her mom as a guideline.

Therefore we can conclude that:

"Chawrdi complied with the guideline because the mean number of hours played is \frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17.

G(n)=n^3+n<br> g(-3)<br> help!
Svetradugi [14.3K]
The question is simply asking you to evaluate the function for an input value of -3. Meaning we plug in -3 for all cases of n. (-3)^3 + (-3). This gives us -27 -3 which is -30. So g(-3)= -30
