Answer:
h=A-πr²÷2πr
Step-by-step explanation:
Making h subject
A=2πrh+πr²
A-πr²=2πrh
A-πr²÷2πr=h
h=A-πr²÷2πr
Y=3/4(8)-5
y=24/4-5
y=6-5
y=1
Answer:
x=6
Step-by-step explanation:
If a line has an undefined slope, then it has to be a <u>vertical line</u>.
Since the line is vertical, there is only one x value for any given y value. This means we can use the x value in the given coordinate pair to find the equation...
x=6
Answer:
Step-by-step explanation:
First of all, you have to set up the equation
2x^2 + x -1 = 2 Subtract 2 from both sides
2x^2 + x - 1 - 2 = -2+2 Combine
2x^2 + x - 3 = 0 This factors.
(2x + 3)(x -1 ) = 0
Either
2x + 3 = 0 Subtract 3 from both sides
2x = - 3 Divide by 2
2x/2 = - 3/2
x = - 3/2 which you already know
or
x - 1 = 0 Add 1
x - 1 + 1 = 1
x = 1
the other answer is x = 1
Answer:
24, 26, 28
Step-by-step explanation:
So the three consecutive even numbers become 'x', 'x+2′, 'x+4′. According to the given condition, the sum of three consecutive even numbers is 78. x=24. Hence the three consecutive even numbers are 24, 26 and 28. is this the answer you were looking for?
