Answer:

Step-by-step explanation:

(3). cos A = [tex]\frac{b}{c}[/tex]

cos A = [tex]\frac{1.77}{17.7}[/tex] = 0.1 ⇒ A ≈ 84.26°

B ≈ 5.74°

C = 90°

a ≈ 17.61

(4). cos 16° = [tex]\frac{79}{x}[/tex] ⇒ x ≈ 82.18 ≈ 82.2 ≈ 82

Answer:

The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

Step-by-step explanation:

The vertex form of the quadratic equation y = ax² + bx + c is

y = a(x - h)² + k, where

Let us use the facts above to solve the question

∵ y = x² + 24x - 15

∵ a is the coefficient of x² and b is the coefficient of x

∴ a = 1 and b = 24

∵ h is the x-coordinate of the vertex point

∵ h = [tex]\frac{-b}{2a}[/tex]

→ Substitute the values of a and b to find h

∴ h = [tex]\frac{-24}{2(1)}=\frac{-24}{2}[/tex]

∴ h = -12

→ To find k substitute y by k and x by h

∵ y = k and x = h

∴ k = (-12)² + 24(-12) - 15 = 144 - 288 - 15

∴ k = -159

∴ The coordinates of the vertex point are (-12, -159)

→ Substitute the values of a, h, and k in the vertex form above

∵ y = 1(x - -12)² + (-159)

→ Remember (-)(-) = (+) and (+)(-) = (-)

∴ y = (x + 12)² - 159

∴ The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

Answer:

If x is the number of ounces the container can hold then x = 32

Step-by-step explanation:

The container can hold 32 ounces because if it was 3/4 full and then you poured out 8 ounces then that means there was 2/4 remaining.

Answer: 70

90+20=110

180-110=70

I hope this is good enough:

Answer:

70

Step-by-step explanation:

Everything needs to add up to 180. So you have 90 and 20 you will add them and you’ll get 110. Since you want to find the missing measurement you will subtract 180-110 and you’ll get 70. The missing angle is 70. To check: 90+20+70=180

Answer:

They are not in a proportional relationship because Monique's number and time isnt a proportion. Instead it is a whole number. Like Braydon's his is 6:2 that is the correct way to write it.

Step-by-step explanation:

The ratio is not proportion.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given:

The ratio of Braydon's number of laps he ran to the time he ran is 6:2.

The ratio of Monique's number of laps she ran to the time she ran is 10:4.

The simplest for Braydon is = 6/2 = 3/1

and, the simplest form for Monique = 10/4 = 5/2

As, 3/1 ≠ 5/2

So, the ratio is not proportion.

first you need to make that into an equation here i think your equation that will help you on that question is 46°+63°=X

Step-by-step explanation:

K-is (4°k+5°y)+(4°k+10°y)=118°

and then what ever you get out of the K's and Y's you will divide that number by 118 and that is the value of K

Answer:

y = 60x + 40

Step-by-step explanation:

It is in the form of

y = mx + b

m is the slope

b is the y intercept.

The y intercept is 40, so it will be y = mx + 40.

The slope is 60, so y = 60x + 40!

Answer:

1. 1/2 or (2,1)

2. 1 or (-3,-3)

3. -2/1 or (-3,6)

Step-by-step explanation:

1. 2-(-3) = 2 + 3 =5

   6-(-4)= 6 +  4= 10

so 1/2 or (2,1)

2. 1-4 = 1 + (-4) = -3

  -2-1 = -2 + (-1)= -3

so 1 or (-3,-3)

3.  12-6 = 12 + (-6) = 6

    2-5 = 2 + (-5) = -3

so  -2/1 or (-3,6)
