Solve for x on the domain 0 < x < 12: cos x= -0.814

Morgarella [4.7K]

Answer:

Replace 10.0 with 10.04

Step-by-step explanation:

$\cos(x) = - 0.814$

$\cos {}^{ - 1} ( - 0.814) = x$

$x = 2.52$

Next, use the identity

$\cos(x) = \cos(2\pi - x)$

$\cos(2.52) = \cos(2\pi - 2.52)$

$\cos(2.52) = \cos(6.28 - 2.52)$

$\cos(2.52) = \cos(3.76)$

So another solution is 3.76

After that, use the identity

$\cos(x + 2\pi) = \cos(x)$

So use that for 2.52 and 3.76

$\cos(2.52 + 2\pi) = \cos(8.80)$

8.80 is one solutiin

$\cos(3.76 + 2\pi) = \cos(10.04)$

Jada makes sparking juice by mixing 2 cups of sparkling water with every 3 cups of apple juice.

MatroZZZ [7]

Answer:

[1] 10

[2] 9

[3] j = 3/2 ⋅ s

Step-by-step explanation:

Jada makes sparking juice by mixing 2 cups of sparkling water with every 3 cups of apple juice.How much sparkling water does Jada need if she uses 15 cups of apple juice?

Answer = 10

Explanation:

Ratio for mixing 2 cups of sparkling water with every 3 cups of apple juice

2 : 3

Thus also means:

2/3 = x/15

Solve for x:

x = 10

-------------------------------------------------------------------------------------------------------------

How much apple juice does Jada need if she uses 6 cups of sparkling water?

Answer = 9

Ratio for mixing 2 cups of sparkling water with every 3 cups of apple juice

2:3

Also means:

2/3 = 6/x

Solve for x

x = 9

-------------------------------------------------------------------------------------------------------------

Let S represent the number of cups of sparkling water and J represent the number of cups of apple juice. Write an equation that shows how S and J are related. Use your answers from the previous question to assist you with your answer.

Answer = j = 3/2 ⋅ s

The graph relates the number of gallons of white paint to the number of gallons of red paint Jess used to make the perfect pink.

Effectus [21]

Answer:

y = $\frac{1}{4}x$

Step-by-step explanation:

Straight line in the graph attached shows the linear relation between number of gallons of white paint and number of gallons of red paint added to prepare pink.

Let the number of gallons of white paint required = x

and number of gallons of red paint required = y

y ∝ x

y = kx [k = proportionality constant]

Since a point (4, 1) lies on this line,

1 = 4k

k = $\frac{1}{4}$

Therefore, equation that describes the relationship will be,

y = $\frac{1}{4}x$
