What is the value of y?<br> O 2/3 units<br> O 4 units<br> O 4/3 units<br> O 8 units

LUCKY_DIMON [66]

Answer:

y = 4 $\sqrt{3}$

Step-by-step explanation:

Using the altitude- on- hypotenuse theorem

( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )

y² = 6 × (6 + 2) = 6 × 8 = 48 ( take the square root of both sides )

y = $\sqrt{48}$

= $\sqrt{16(3)}$ = $\sqrt{16}$ × $\sqrt{3}$ = 4 $\sqrt{3}$

15) Which equation does not represent a function?

givi [52]

The answer is D as it can be rewritten as -((y^2)/5)-(8/5)=x. Solving for the x-intercepts you get -((y^2)/5)-(8/5) = 0 as you want to find the y values when x is zero. Solving for y you get: (y^2)/5)+(8/5) = 0 => (y^2)/5)=-(8/5) => y^2=-8 => y = plus or minus sqrt(-8). The first problem is that you have 2 x intercepts which already makes it not a function and second sqrt(-8) is an imaginary number making the solution not a real number.

matrenka [14]

Answer:

168 minutes

Step-by-step explanation:

It takes 120 minutes for the first person to clean the jellyfish tank.

This means that in 1 minute the first person cleans $\frac{1}{120}$ of the tank.

Let the time taken by the second person working alone to clean the tank be x minutes.

Then in 1 minute the second person cleans $\frac{1}{x}$ of the tank.

Working together, the two persons clean,

$\frac{1}{120} + \frac{1}{x}$ of the tank

But it is given that the two persons working together can clean the tank in 70 minutes. This means that in 1 minute both of them can clean $\frac{1}{70}$ of the tank.
