For every hour of exercise, Tina drinks 8 ounces of water. What is the ratio of hours to water

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

5)

Adj = 14

Hyp = 26

∠X

so use

CAH

Cos(X) = 14/26

X = arcCos(14/26)

X = 57.421°

X = 57.4 ° ( rounded to nearest 10th )

6)

∠X

Hyp = 46

Opp = 12

use SOH

Sin(x) = 12/46

X = arcSin(12/46)

X = 15.121°

X = 15.1 ° ( rounded to nearest 10th )

7)

∠X

Adj = 29

Opp = 24

use TOA

Tan(x) = 29 / 24

X = arcTan( 29 /24)

X = 50.389

X = 50.4 °  ( rounded to nearest 10th )

8)

∠X

Adj = 22

Opp = 6

use TOA agian

Tan(x) = 6 / 22

X = arcTan(6/22)

X = 5.194

X = 5.2 °  ( rounded to the nearest 10th )

The answer for the question is 3/10

Answer:

-8+14x

Step-by-step explanation:

By distribution, -2(4-7x) = -8+14x

Answer:

y = - ( x + 2 )² + 14

Step-by-step explanation:

f(x) = ax² + bx + c

f(x) = a(x - h)² + k (where (h, k) are coordinates of the vertex.

h = - [tex]\frac{b}{2a}[/tex]

~~~~~~~~~~~~

f(x) = - x² - 4x + 10

a = - 1, b = - 4, c = 10

h = - [tex]\frac{-4}{2(-1)}[/tex] = - 2

k = - ( - 2)² - 4( - 2) + 10 = 14

(h, k) = ( - 2, 14 )

y = - ( x + 2 )² + 14

Answer:

The perimeter of a square is 20

if length of the square is x

perimeter of a square = x + x+ x + x = 4x = 20

4x = 20

x= 20/4

x = 5

Let get the length of one of the diagonal is y

According to the Pythagoras  low,

y^2 = x^2 + x^2

y^2 = 5^2 + 5^2

y^2 = 25 + 25

y^2 = 50

y= sqrt(50)

The simplification of the expression is 48√2

The procedure in mathematics to utilize and analyze the function or expression to make the function or expression uncomplicated or more coherent is called simplifying and the process is called simplification.

We are given the expression as;

2√98-8√32+3√72

​

Now we have to simplify

2√98-8√32+3√72

​

2√(49×2)  - 8√(4×2) + 3 √(36×2)

Now taking common;

2 x 7√2 + 8 x 2√2 + 3 x 6√2

14√2 + 16√2 + 18√2

? + 31° + 94° = 180°

? + 125° = 180°

? = 180° - 125°

? = 55°

Answer: 52°

Step-by-step explanation:

Angles in a triangle always add up to 180°.

So to work out what the missing angle is, you would have to add 34 and 94 together.

34+94=128

Then you would have to take 128 away from 180.

180-128=52°

Answer:

x = 52°

Step-by-step explanation:

I have attached an image to depict the given angles.

From the attached image, we can see that the unknown angle is x°.

Thus, since that corner is 90°, then;

x + 38 = 90

Subtract 38 from both sides to get;

x = 90 - 38

x = 52°

Answer:

k = 2

Step-by-step explanation:

3(-1) + k(5) = 7

-3 + 5k = 7

5k = 10

k = 2

The value of K in the equation 3x + Ky =7 is 2.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

Equation 3x + Ky =7.

And we have also given that (-1, 5) satisfies the equation.

That means,

(-1, 5) is a solution of the equation.

To find the value of K;

Substitute the value of x = -1 and y = 5

So,

3x + Ky =7,

3(-1) + K(5) =7

-3 + 5K = 7

5K = 10

K = 2

Therefore, the value of K is 2.
