Answer:

56 cm

Step-by-step explanation:

perimeter = the length of the sides.

Answer:

56 cm

Step-by-step explanation:

The perimeter of a shape is just all the lengths added  together. So 5+5+5= 15 and 10+10+13=33 and 4+4=8. 15+33+8=56. Hence 56 is the answer

An oblique cylinder has a diameter of 14 units. The volume of the cylinder is 1,176π cubic units. An oblique cylinder has a diam
frozen [14]

Answer: The height of the cylinder is 24 units.

Step-by-step-explanation: The volume of a cylinder is calculated as

Volume = Pi x r^2 x h

Where r is the radius, and h is the height. The radius shall be derived as half of the diameter, that is, half of 14 units which equals 7 units. The volume has been given as 1176 Pi cubic units. We can now substitute for the values given as follows;

1176 Pi = Pi x 7^2 x h

1176 Pi = Pi x 49 x h

By cross multiplication we now have

(1176 Pi)/49 Pi = h

1176/49 = h

24 = h

Therefore the height of the cylinder is 24 units.

Without sketching the graph, find the x-intercepts and y-intercepts of the graph of the equation y=x²-x-6 What is/are the x-inte
oksian1 [2.3K]

Given the equation:

y=x^2-x-6

Let's find the x-intercepts and the y-intercepts of the graph.

• x-intercept:

The x-intercept are the points where the parabola crosses the x-axis. At x-intercept the y-value is zero.

To find the x-intercepts, substitute 0 for y and solve for x.

We have:

0=x^2-x-6

Rewrite the equation:

x^2-x-6=0

Factor the left hand side of the equation:

(x-3)(x+2)=0

Equate each factor to zero:

x - 3 = 0

Add 3 to both sides:

x - 3 + 3 = 0 + 3

x = 3

x + 2 = 0

Subtract 2 from both sides:

x + 2 - 2 = 0 - 2

x = -2

Therefore, the x-intercepts are:

3, -2

• y-intercept:

The y-intercept is the point where the parabola crosses the y-axis. The x-value at the y-intercept is zero.

To find the y-intercept, substitute 0 for x and solve:

\begin{gathered} y=0^2-0-6 \\  \\ y=-6 \end{gathered}

Therefore, the y-intercept is -6.

In point form:

x-intercept: (3, 0), (-2, 0)

y-intercept: (0, -6)

ANSWER:

A. The x-intercepts are (3, 0), (-2, 0)

A. The y-intercept is (0, -6)

Three coins are placed in a bag. Each coin is labeled "1", "2", or "3". A coin is drawn from the bag, recorded, and then placed
Tpy6a [65]

Answer:

1/3 or 33.33%

Step-by-step explanation:

Each draw is an independent event, and it doesn't happen what happened before, since the coin is placed back in the bag, recreating the same scenario.

There are 3 coins in the bag... so drawing out the coin labeled '1' is one possibility out of three possible outcomes.

1/3 or 33.33%
