X = 12.5 hours.

Ywp = (9*6)/15

Ywp = 3.6 aprox 4 water pumps

Write the standard equation for the circle with center (6, –8) that passes through (0, 0).(x – 6)2 + (y + 8)2 = 0(x – 6)2 + (y +
Anna [14]
Your equation is:

(x - 6)² + (y + 8)² = 100

When you plug in (0, 0) into this equation, you get:
(0 - 6)² + (0 + 8)² = 100
(- 6)² + 8² = 100
36 + 64 = 100
100 = 100

3/4 + -3/8 + -1/4=?<br> Evaluate the expression
Ann [662]

Answer: -1/8

Step-by-step explanation:

3/4 + -3/8 + -1/4

Find the LCM of 4, 8, and 4

That's 8 so you make an equivalent fraction for all fractions so the denominator is 8.

3/4 = 6/8

-3/8 = -3/8

-1/4 = -4/8

Now the expression looks like this:

6/8 + - 3/8 + -4/8

6/8 - 3/8 - 4/8

6/8 - 7/8

-1/8

Hope that helped!

Alekssandra [29.7K]

Answer:

x=[15:-5:-25]'

Step-by-step explanation:

In order to create a vector you need to use this command:

x = [j:i:k]'

This creates a regularly-spaced vector x using i as the increment between elements. j is the initial value and k is the final value. Besides you need to add the character ' at the end in order to convert the arrow vector in a column vector
