Answer:
I think it is 13 and 19 but im not sure
Step-by-step explanation:
X=3 and y=x^2 intersect at (3,9), so your bounds are y=4 and y=9 and and . , so you use the disk method therefore you have to switch variables (even though x^2 is not invertible, because you only need the right side you can use y^(1/2)) so pi*integral( 3^2- (y^(1/2))^2 dy) making it pi*[9y-(1/2)y^2]|y=(4,9) , pi*[25/2]
Answer:
7.5 days
Step-by-step explanation:
A working = 10 days
AB working = 4 days
AB = 4 --> 10B = 4
/10 /10
B = .4
AB = 3
A(.4) = 3
/.4 /.4
A working alone = 7 .5 days
<em>*pretty much solve for B and then equal AB to the amount of days the worked together before B left, 3 days, then it gives you the amount of time A must work to finish the house alone*</em>
Answer:
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12x' to each side of the equation.
-15 + -15x + 12x = -12x + 12x
Combine like terms: -15x + 12x = -3x
-15 + -3x = -12x + 12x
Combine like terms: -12x + 12x = 0
-15 + -3x = 0
Add '15' to each side of the equation.
-15 + 15 + -3x = 0 + 15
Combine like terms: -15 + 15 = 0
0 + -3x = 0 + 15
-3x = 0 + 15
Combine like terms: 0 + 15 = 15
-3x = 15
Divide each side by '-3'.
x = -5
Simplifying
x = -5 so the answer is x=5(56+)_-2 pls give me brainlyest
The answer is x=16 just cross multiply
