Step-by-step explanation:

x-intercept: where y = 0

Set y to zero to find x.

0 = ½x + 3

-3 = ½x

x = -6

(-6, 0)

Write the first five terms of the sequence.. NO LINKS!!!

just olya [345]

Answer:

5,50,500,5000,50000

Step-by-step explanation:

The first term is given

a1 =5

The second term is when n=2

a2 = 10 * a1 = 10 * 5 = 50

The third term is when n=3

a3 = 10 * a2 = 10 * 50 = 500

The fourth term is when n=4

a4 = 10 * a3 = 10 * 500 = 5000

The fifth term is when n=5

a5 = 10 * a4 = 10 * 5000 = 50000

What is the sector area created by the hands of a clock with a radius of 9 inches when the time is 4:00? 6. 75π in. 2 20. 25π in

Blizzard [7]

The sector area created by the hands of a clock with a radius of 9 inches when the time is 4:00 is 27π square inches. Then the correct option is C.

<h3>What is a circle?</h3>

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The sector area is created by the hands of a clock with a radius of 9 inches when the time is 4:00.

Then the radius (r) is 9 inches and the angle is 120°.

We know that the area of the sector is given by

$\rm Area\ of \ sector = \dfrac{\theta}{360} \pi r^2 \\\\\\Area\ of \ sector = \dfrac{120}{360} \pi * 9^2\\\\\\Area\ of \ sector = 27 \pi$

The sector area created by the hands of a clock with a radius of 9 inches when the time is 4:00 is 27π square inches. Then the correct option is C.

Find the surface area of the solid. Round your answer to the nearest tenth. Explain your answer. please help due tomorrow..

Elan Coil [88]

Answer:

226 ft²

Step-by-step explanation:

The surface of the figure can be considered in several parts:

a) top and bottom surfaces

b) outside surfaces

c) inside surfaces

The top and bottom surfaces each consist of a rectangle 8 ft by 4 ft with a 4 ft by 1 ft hole. The area of the larger rectangle without the hole is the product of its length and width:

(8 ft)(4 ft) = 32 ft²

The area of the hole is the product of its length and width:

(4 ft)(1 ft) = 4 ft²

Then the area of the surface around the hole is the difference of these:

32 ft² - 4 ft² = 28 ft²

The top and bottom surfaces together have twice this area for a total of ...

top and bottom area = 2·(28 ft²) = 56 ft²

The outside (lateral) area is the total area of the four rectangles that make up the sides of the figure. Each rectangle has a height of 5 ft, so we can compute the area by finding the perimeter of the figure and multiplying that by 5 ft.

The perimeter is the sum of the lengths of its top or bottom edges:

8 ft + 4 ft + 8 ft + 4 ft = 2·(8 ft +4 ft) = 2·12 ft = 24 ft

Then the lateral area is ...

outside lateral area = (5 ft)(24 ft) = 120 ft²

The area of the sides of the hole can be computed the same way. The hole is 5 ft high and its edge lengths are 1 ft and 4 ft. Then the total inside lateral area is ...

inside lateral area = (5 ft)(2·(1 ft + 4ft)) = 50 ft²

So the total surface area of the solid is ...

total area = top and bottom area + outside lateral area + inside lateral area

total area = (56 + 120 + 50) ft²

total area = 226 ft²
