Simplify this expression: 19 – (–8) – (–14) = ?
A. 41
B. –7
C. –3
D. 25

Answers

Answer 1

Answer: When you are subtracting a negative, you treat it as if you are adding a positive. So 19-(-8) would be 19 + 8 which is 27. Then do the same thing with the 14, so instead of 27 -(-14) it's 27 + 14 which is 41. So your answer is 41. I hope this helps! XD

A piece of wire is used to form the framework of a cube. The volume of the cube is 2744 cubic inches. Find the length of the wire

Answers

Answer:

56 inches (perimeter) * 14 inches (height) = 784 inches

Step-by-step explanation:

To find the length of the wire used to form the framework of a cube, we need to consider the perimeter of the cube's base and multiply it by the height of the cube.

The volume of the cube is given as 2744 cubic inches. Since the volume of a cube is calculated by multiplying the length, width, and height of the cube, we can find the length of each side of the cube by taking the cube root of the volume.

∛2744 = 14

So, each side of the cube measures 14 inches.

To find the perimeter of the cube's base, we multiply the length of one side by 4 (since the base of a cube has 4 sides of equal length).

14 inches * 4 = 56 inches

Therefore, the perimeter of the cube's base is 56 inches.

To find the length of the wire used to form the framework of the cube, we multiply the perimeter of the base by the height of the cube. Since all sides of a cube are equal, the height is also equal to the length of one side, which is 14 inches.

56 inches (perimeter) * 14 inches (height) = 784 inches

So, the length of the wire used to form the framework of the cube is 784 inches.

Answer:

168 in

Step-by-step explanation:

Volume of a cube = length*width*height

Cubic root of 2744 = 14

Cube = 4 length+4 width+4 heights = 12

14 + 12 = 168 in of wire

If f(x) and its inverse function, f–1(x), are both plotted on the same coordinate plane, what is their point of intersection?

a)
(0, –2)
b)
(1, –1)
c)
(2, 0)
d)
(3, 3)

Answers

Answer:

Option d) (3,3)

Step-by-step explanation:

A function f(x) and its inverse f^(-1) (x) are symmetrical with respect the right line y=x, then their point of intersection is when they cross the right line y=x. In the attached graph we draw the right line y=x, and the function f(x) crooses this line at the point (3,3), then this point is their intersection point.

answer is d

Which phrase best describes the translation from the graph y=2(x-15)^2 +3 to the graph of y= 2(x-11)^2 +3

Answers

Answer:

The graph $y=2(x-15)^2 +3$ is shifted left by 4 units .

Step-by-step explanation:

Function : $y=2(x-15)^2 +3$

Rule : f(x)→f(x+b)

The graph f(x) shifts left by b units.

Now Shift the given graph left by 4 units

So, $y=2(x-15)^2 +3$ → $y=2((x+4)-15)^2 +3$ →tex]y=2((x-11)^2 +3[/tex]

Thus the shifted graph is $y= 2(x-11)^2 +3$

Thus the graph $y=2(x-15)^2 +3$ is shifted left by 4 units .

Hence the phrase best describes the translation is the graph $y=2(x-15)^2 +3$ is shifted left by 4 units and the obtained graph is $y= 2(x-11)^2 +3$

to eliminate the +2 in the first graph, it would need to move 2 units right.
to add the +3 to the first graph, it would need to move 3 units up.

2 units right and 3 units up.

7 times the difference of a number and 3.2 is 8.4.

because subtraction comes before multiplication on the order of operations we have to put in parenthasis in this problem.

(x-3.2) is what we have so far.

then we multiply it by 7

so 7(x-3.2)=8.4
