which equation in point slope form correctly represents zadas pay in dollars, y, when she works x hours?

Firlakuza [10]

ANSWER

The correct answer is A

$y-68=2(x-4)$

EXPLANATION

We were told that Zada is paid at an hourly rate of $ $12$ per hour.

The unit rate of payment represents the slope of the straight line graph that models Zada's earnings. Thus $m=12$

When she works for 4 hours she earns a total of $68 tells us that the point, $(4,68)$ lies on the model straight line.

Using the formula for the point slope form

$y-y_1=m(x-x_1)$

we obtain the equation as follows.

$y-68=2(x-4)$

Antonia likes calculating the sum of the digits that she sees on

asambeis [7]

Answer:

23

Step-by-step explanation:

The 12 hour clock doesn't go past 12 on the first 2 digits (hour).

The 24 hours goes 13:, 14:, 15: and so on.

We now have to figure out "4" largest numbers on the 12-hr clock and add them to get the max sum out of them.

The hours are:

...

The largest sum would be that of "09"

Now, the minutes:

59 is the highest minute and that will give us the highest sum

So, the time we are looking for is:

09:59

The sum is:

0 + 9 + 5 + 9 = 23

Solve for x and y please!

galina1969 [7]

Answer:

$x = 8$

$y=2\sqrt{3}$

Step-by-step explanation:

The figure is composed of 3 Right triangles. To find the values of the variables x and y we use the Pythagorean theorem to propose one equation.

$x^2 =4^2 + (4\sqrt{3})^2$

Now we solve for x

$x=\sqrt{4^2 + (4\sqrt{3})^2}$

$x=\sqrt{16 +16*3}\\\\x=\sqrt{64}\\\\x=8$

Let's call z at the angle opposite to y

Then we have that:

$sin(z) =\frac{opposite}{hypotenuse}$

Where

$hypotenuse = 8$

$opposite=4$

$sin(z) =\frac{4}{8}$

$z=sin^{-1}(\frac{1}{2})$

$z=30$

Now we use this angle to find the length y

$sin(z) =\frac{opposite}{hypotenuse}$

Where in this case

$hypotenuse = 4\sqrt{3}$

$opposite=y$

$z=\°30$

$sin(30\°) =\frac{y}{4\sqrt{3}}$

$y=sin(30\°)*4\sqrt{3}$

$y=2\sqrt{3}$
