Answer:

5.006

41.056

31.289

51.977

7.884

Step-by-step explanation:

1) sin x = opposite side / hypotenuse

sin 24.3° = 2.06 / hyp

hyp = 2.06 / sin 24.3  = 5.<u>0059</u>006616019108320511866543651

rounding to 3 significant figures

= 5.006

2)cos x = adjacent side / hypotenuse

cos 47 = 28 / x

x = 28 / cos 47 = 41.<u>0558</u>17197909497891901840157945

= 41.056

3) cos x = adjacent side / hypotenuse

cos 56.1 = x / 56.1

x = 56.1 * cos 56.1 = 31.<u>2895</u>00613760617368691451544764

= 31.289

4) tan x = opposite side / adjacent side

tan 68 = x / 21

x = 21 * tan 68 = 51.<u>9768</u>239217422123300402781676

= 51.977

5) sin x = opposite side / hypotenuse

sin 21 = x / 22

x = 22 * sin 21 = 7.<u>8840</u>948899966060166510313670963

= 7.884

Hannah was adding 5 plus -4. When explaining her work she said that the sum is 9 because you add the numbers and take the sign o
Scilla [17]

Answer:

The sum is 1

Step-by-step explanation:

When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.

Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.

If the factors of a quadratic function are (x + 2) and (x − 9), what are the x-intercepts of the function?
Zielflug [23.3K]

Answer: D. (-2,0) and (9,0)

Step-by-step explanation:

When you equate the factors to 0 you get

(X+2) = 0

X = -2

(X-9) = 0

X= 9

Here the Y value is 0 as you find the factors of x when the Y value is 0.

So the answer is (-2,0) and (9,0)

If AB = 13, BC = 9, and CA = 17, list the angles of ABC in order from smallest to largest.
svp [43]

Across the largest side is going to be largest angle, and across the smallest side -smallest angle.

Sides:

BC = 9 < AB = 13 < CA = 17.

Angles that are across sides: A < C < B.


Answer is d- A C B.
