Answer:

C. 448

Step-by-step explanation:

Since 38-18=20, you divide by 10 to find the base of the two triangles on the side. The height of the triangle is 16 and the formula is basexheightx1/2.

10x16x0.5=80

You then multiply that by two because there are two triangles

80x2=160

You then have to find the rectangle in the center, which is 16x18=288 cm

Then we add it all up

160+288=448

Answer:

${ \underline{ \sf{\int\limits^2_1 {x^{2}-8x+8 } \, dx} \: = \: - 1}}$

Step-by-step explanation:

${ \tt{\int\limits^2_1 {x^{2}-8x+8 } \, dx}} \\ \\ = { \tt{[ \frac{ {x}^{3} }{3} - 4 {x}^{2} + 8x ] {}^{2} _{1}}}$

Substitute x with the limits:

$= { \tt{( \frac{ {2}^{3} }{3} - 4( {2)}^{2} + 8(2)) - ( \frac{ {1}^{3} }{3} - 4( {1)}^{2} + 8(1)) }} \\ = { \tt{( \frac{8}{3} - \frac{11}{3} )}} \\ \\ = { \tt{ - 1}}$

.The diameter of a bike wheel is 27 inches. If the wheel makes 15 complete rotations, how far does the bike travel?

kobusy [5.1K]

Answer:

1271.7in

Step-by-step explanation:

A complete rotation is = circumference of the wheel.

So calculate the circumference which is pi times diameter.

27 times pi (which is 3.14) = 84.78in one rotation

so if you make 15 rotations, you are multiplying it by 15

15 x 84.78 = 1271.7in
