Answer:

radius of the sphere = 4 feet

Step-by-step explanation:

Volume of a sphere = \frac{4}{3} \pi r^3

given volume is 268 cubic feet

Replace volume with 268

268= \frac{4}{3} \pi r^3

Multiply by 3/4 on both sides, use 3.14 for pi

201= 3.14 * r^3

Divide by 3.14 on both sides and then take cube root

64.01273885=r^3

r=4

So radius of the sphere = 4 feet

<h3>Answer: Choice C</h3>

=================================================

Explanation:

For choice C, the x values are out of order, so it might be tricky at first. I recommend sorting the x values from smallest to largest to get -2, -1, 0, 1, 2. Do the same for the y values as well. Make sure the correct y values stay with their x value pairs. You should get the list of y values to be 4, 2, 1, 1/2, 1/4

Check out the attached image below for the sorted table I'm referring to

We can see the list of y values is going down as x increases. This is a good sign we have decay. Further proof is that we multiply each term by 1/2 to get the next one

4 times 1/2 = 2

2 times 1/2 = 1

1 times 1/2 = 1/2

1/2 times 1/2 = 1/4

and so on. Effectively we can say the decay rate is 50%

Point-slope form: y - 5 = (-1/5)(x - 7)

standard form: x + 5y = 7

slope-intercept form: y = (-1/5)x + (7/5)
***note: (-1/5) = -0.2 and (7/5) = 1.4

<em>Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.</em>

<em>                               b² = a² + c² - 2ac(cosB)</em>

<em>Substituting the known values,</em>

<em>                          (1.8)² = (2.4)² + (1.6)² - 2(2.4)(1.6)(cosB)</em>

<em>The value of B from the equation is 48.6°. </em>

dezoksy [38]

Answer:

12 square inches.

Step-by-step explanation:

Please consider the complete question.

A model ship has a mast that is 7 inches tall. A right triangular sail goes from the top of the mast to 1 inch from the bottom of the mast. The length of the base of the sail is 4 inches. The height of the sail is along the mast. Find the area of the sail.

The sail will form a right triangle with respect to mast, whose height is 6 inches and base is 4 inches as shown in the diagram.

The area of the sail will be equal to area of triangle.

\text{Area of triangle}=\frac{1}{2}(\text{Base}\times\text{Height})

\text{Area of triangle}=\frac{1}{2}(4\text{ in}\times6 \text{in})

\text{Area of triangle}=2\text{ in}\times 6 \text{in})

\text{Area of triangle}=12 \text{ in}^2

Therefore, the area of the sail is 12 square inches.
