Find the endpoint:
scZoUnD [109]

Answer:

The coordinates of Point D are: (-5,-8)

Step-by-step explanation:

The formula for mid-point is given by:

M = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})

For the point (x1,y1) and (x2,y2)

Given that

M = (-3, -6)

C = (-1, -4) => (x1,y1)

Putting the values of given points in the formula for mid-point

(-3,-6) = (\frac{-1+x_2}{2} , \frac{-4+y_2}{2})

Putting respective coordinates equal

-3 = \frac{-1+x_2}{2}\\-6 =-1+x_2\\x_2=-6+1\\x_2 = -5\\AND\\-6 = \frac{-4+y_2}{2}\\-12 = -4+y_2\\y_2 = -12+4\\y_2 = -8

Hence,

The coordinates of Point D are: (-5,-8)

We can calculate the depth ddd of snow, in centimeters, that accumulates in Harper's yard during the first hhh hours of a snowst
inna [77]

Answer:

0.2 hours

Step-by-step explanation:

The depth, d of snow (in cm) that accumulates in Harper's yard during the first h hours of a snowstorm can be calculated using the equation:

d=5h

When d=1cm, we want to determine the value of h.

1=5h

h=1/5=0.2

Therefore, it takes 0.2 hours for 1 centimeter of snow to accumulate in Harper's yard.

Myra wrote a computer program that had 75 lines of code. She realized that she could make the code more efficient and removed 20
jeka94

Answer:

Now Myra has 60 lines of code, no grid picture attached.

Step-by-step explanation:

If Myra removed 20% of the lines and she started with 75 lines of code, then she is removing 1/5 of those lines of code.

75 divided by 5 is 15, and 75 - 15 = 60

Now Myra would have 60 lines of code. It's unclear what grid you are talking about though - could you attach a picture of the grid you need to shade in?

What relationship do the ratios of sin x° and cos y° share?
puteri [66]

Answer:

The ratios are both identical (3/5 and 3/5).

Step-by-step explanation:

sin x° is equivalent to O/H, or the opposite/hypotenuse sides of the triangle. Therefore:

sin x° = 3/5.

cos y° is equivalent to A/H, or the adjacent/hypotenuse sides of the triangle.

cos y° = 3/5.

\frac{3}{5} =\frac{3}{5}

The ratios are identical.
