Referring to the Fig. in Question #40, find the unknown
length Y.

Answer:

tan30°=7/x

[tex] \frac{1}{ \sqrt{3} } = \frac{7}{x } \\ x = 7 \sqrt{3} [/tex]

cos30°=x/y

[tex] \frac{ \sqrt{3} }{2} = \frac{7 \sqrt{3} }{y} \\ \\ 7 \sqrt{3} \times 2 = \sqrt{3} \times y \\ \frac{7 \sqrt{3 } \times 2}{ \sqrt{3} } = y \\7 \times 2 = y \\ 14 = y[/tex]

tell me if it's wrong.

Dudley and Bob monitored the distance their pet turtle could walk in a certain amount of time. The table shows their results. The table of values represents a proportional relationship. time (minutes) 5 Distance (inches) 14.5
14 40.6
19 55.1
25 72.5
b.) Write an equation for the distance traveled by the turtle based on the number of minutes. c.) Identify the constant of proportionality in part (b). What does it mean in this context? d.) Use your equation in part (b) to write an equation for the time it would take for the turtle to travel a given distance. e.) Identify the constant of proportionality in part (d). What does it mean in this context?

A fish is hovering at –320 feet in relation to sea level. Then it descends 2 feet per second for 8 seconds. Brenda says that the new position of the fish in relation to sea level is represented by the equation below.

2 times 8 + (negative 320) = 336

Which explains whether Brenda is correct?
1. Brenda is correct because her answer represents 336 feet below sea level.
2. Brenda is correct because Negative 16 + (negative 320) = 336.
3. Brenda is not correct because the new position is 2 times 8 + (negative 320) = negative 304.
4. Brenda is not correct because the equation should be Negative 2 times 8 + (negative 320) = negative 336.
