All real numbers y that are less than -8 and at most 0

Mathematics
1 answer:
dalvyx [7]3 years ago
5 0
That’s mathematically impossible.

If the set of numbers are less than -8, they cannot be less than or equal to 0.

Reading a graph wrong is a common mistake. A line pointing right means greater than.

If that’s the case, this problem is an “and” problem, in algebra. The answer is both; -8
or
-8

AC is diagonal of square ABCD, and the length of AC is 4. What is the area of the square?
dybincka [34]
Option d.
as we know the corner of a square is always 90°. So we can apply that (side of the square)^2+(side of the square)^2 = (diagonal of the side)^2

(side of the square)^2+(side of the square)^2 = 16
16/2=8
8=(side of the square)^2
side of square= squareroot of 8
area of square= squareroot of 8^2=8
hence answer is 8

A functionf(x) is graphed on the coordinate plane.
ollegr [7]

Answer:

y = -1/2x +1

Step-by-step explanation:

The y intercept is 1 (this is where it crosses the y intercept)

(0,1) and (2,0) are two points on the line

The slope is given by

m = (y2-y1)/(x2-x1)

   = (0-1)/(2-0)

   = -1/2

The slope is -1/2

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

y = -1/2x +1

HELP MEE!!!|||||||||Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use 3
natulia [17]

Answer: There are several information's of immense importance already given in the question. Let us write them down first.

Diameter of the cylinder = 6 inches

Then

Radius of the cylinder = 3 inches.

Height of the cylinder = 3 * radius

                                  = 3 * 3

                                  = 9 inches

Volume of the cylinder = (pi) * (Radius)^2 * Height

                                   = 3.14 * (3)^2 * 9

                                   = 3.14 * 9 * 9

                                   = 254.34 cubic inches
