Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation
Olenka [21]

Answer:

y = \frac{49}{3}

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 7 when x = 3

k = \frac{y}{x} = \frac{7}{3}, thus

y = \frac{7}{3} x ← equation of variation

When x = 7, then

y = \frac{7}{3} × 7 = \frac{49}{3}

A viewfinder has a triangular lens. Some of the measurement of the length are shown below. Which of the following best represent
S_A_V [24]

Answer:

A

Step-by-step explanation:

First, we need to find the unknown angle of the triangle.

40 + 20 = 60

180 - 60 = 120

So the unknown angle is 120.

Then, we can use the law of sines to create a proportion.

sin(120)/8 = sin(40)/a

Then, we can simplify this.

a is about 5.9, or answer choice A.
