No, it is equal to the decimal -.3333... 1/3^-1 however, would be equal to three since the negative exponent could be brought to the top and made positive, maybe that's what you were thinking of?
Volume of a cylinder = pi x r^2 x h
R is the radius which is given as 2 inches.H is the height given as 6 inches.
Using 3.14 for pi:
Volume = 3.14 x 2^2 x 6
Volume = 75.36 cubic inches
Answer:
W'(27,45)
Step-by-step explanation:
First we must fnd the scale factor of the dilation and then multiply the coordinates of W(3,5) by the scale factor.
Let k be the scale factor of the dilation centered at the origin.
The mapping for a dilation by a scale factor k is
But we were given the coordinates of the image, which is
Q'(-27,36)
Comparing coordinates:
We could compare the first coordinates too and get the same result.
The image of W(3,5) is given by:
Answer:
x=5 or -3
y=-3 or 5
(x,y) =(5,-3) , (-3,5)
Step-by-step explanation:
Suppose,
Those two numbers are respectively x & y .
now,
Two numbers multiplied together give -15
so, x . y = -15
∴y =-15/x .........(1)
They add together to give 2 .
so, x+y= 2
=> x+(-15/x) = 2 [From equation (1)]
=>x-15/x = 2
=>(x²-15)/x = 2
=>x²-15 = 2x [Multiply both sides by x]
=>x²-2x-15 = 0
=>x²-5x+3x-15 = 0
=>x(x-5)+3(x-5) = 0
=>(x-5) (x+3)=0
therefore,
x=5 or x=-3
If x=5,
y = -15/5 [From equation (1)]
∴<em>y= -3</em>
If x=-3,
y = -15/-3 [From equation (1)]
∴<em>y=5</em>
