Answer:

(-1, -1)

Step-by-step explanation:

(1, -1) is a point in Quadrant IV whose radius (length of the ray from (0, 0) to the circle) is √2 (according to the Pythagorean Theorem).

If we rotate this ray 90° clockwise, we'll end up in Quadrant III, with the ray forming a 45° angle with each the x-axis and the y-axis.

This new point will be (-1, -1).

What integer increased by - 12 is 28?

guajiro [1.7K]

Answer:

Step-by-step explanation:

Let n represent the integer. Then the increase can be written as ...

n + (-12) = 28

We can add 12 to both sides of this equation:

n + (-12) + (+12) = 28 +12

n + 0 = 40 . . . . . . -12 and 12 total to zero; 28 and 12 total to 40.

n = 40

The integer is 40.

The volume of a cylindrical container

Ray Of Light [21]

Answer:

A. $\frac{3}{4}\textrm{ gal}$

Step-by-step explanation:

Given:

Volume of the cylindrical container before dilation, $V_{i}=1\textrm{ gal}$

Scale factor of the dilation, $SF=\frac{3}{4}$

Therefore, the volume of the dilated cylinder is given as:

$V_{f}=SF\times V_{i}$

Plug in 1 gal for $V_{i}$ and $\frac{3}{4}$ for SF. Solve for $V_{f}$ . This gives,

$V_{f}=\frac{3}{4}\times 1\\V_{f}=\frac{3}{4}\textrm{ gal}$

Therefore, the volume of the dilated cylinder is $\frac{3}{4}$ gallons.
