Start by multiplying everything out on the right side.
A=1/2hb+1/2hB

Move things around so that you get the clump with "b" in it alone on a side.
A-1/2hB=1/2hb

Start to isolate b.
(A/h)-1/2B=1/2b
(2A/h)-B=b

The answer is b=(2A/h)-B. You don't need the parenthesis, just put the thing in the parenthesis into one fraction.

Hope this helps!

Does anyone know the answer to this?
bezimeni [28]

Hey there!


First, let's find s:

s = (5 + 6 + 7) /2 = 9


Second, let's plug in the numbers into the formula:

A = \sqrt{9(9-7)(9-5)(9-6)}


Third, let's simplify the numbers to get one number under the square root:

A = [tex]\sqrt{216}


Fourth, we'll find the square root of 216 to get the area:

A = 14.697


Therefore, your answer is A.


Hope this helps!! :)

The standard diameter of a golf ball is 42.67 mm. A golf ball factory does quality control on the balls it manufactures. Golf ba
sergiy2304 [10]

THE ANSWER IS A:

This is the function:

f(x)=|42.67-x|.

42.670 -.002 =42.668

42.668 mm to 42.670

Explanation:

Production will be stopped if the difference in diameter is greater than 0.002 mm.

This difference can mean that the golf ball has a diameter more than 0.002 larger than 42.67 mm, or a diameter more than 0.002 smaller than 42.67. This is the reason for using an absolute value function.

 Absolute value represents the distance a number is from 0. For this function, we would want only the values where the function is less than 0.002.

Find the standard equation of a circle that passes through the point (−1, 1) with center (2, 3).
Firlakuza [10]
The equation of a circle is
  (x-h)² + (y-k)² = r²
for center (h, k) and radius r. Of course, the radius can be computed by putting the point in the equation.
  (x-2)² + (y-3)² = (-1-2)² + (1-3)² = 9+4 = 13

The standard equation of the circle is (x-2)² + (y-3)² = 13.
