Answer:
28 is the answer
Step-by-step explanation:
Took k-12 unit test
Yeah it’s 33.3 because there 3 feet in a yard and 100 divided by 3 is 33.3 repeating.
Answer:
You can't unless it is improper
Step-by-step explanation:
if it was 35/23 the answer would be 1/12/23
An equation for the volume of the prism as a function of the height is Volume = h³ + 2h² - 15h.
- We are given a rectangular prism.
- A rectangular prism is no different than a cuboid.
- Let the height of the rectangular prism be "h".
- The length of the rectangular prism is "h-3".
- The width of the rectangular prism is "h+5".
- The volume of the rectangular prism is the same as that of the cuboid.
- The volume of the rectangular prism is the product of its length, its width, and its height.
- The volume of the rectangular prism is (h - 3)*(h + 5)*h.
- An equation for the volume of the prism as a function of the height is :
- Volume = (h - 3)*(h + 5)*h
- Volume = (h² + 2h - 15)*h
- Volume = h³ + 2h² - 15h

Let's consider the man rows to point D, at x km from C...so we have DB= (4-x) km
<span>AC = 4 km </span>
<span>CD = x km </span>
<span>AD = √(4^2 + x^2) ..... Distance travelled through river </span>
<span>Travel on land = (4 - x) </span>
<span>f(t) = distance / time </span>
<span>= [(x^2 + 16)^1/2]/6 + (4-x)/8 </span>
<span>f'(t) = 1/6 * (x^2 + 16)^(-1/2) * (2x) + 1/8 * (-1) </span>
<span>= x / [3*√(x^2 + 16)] -1/8 </span>
<span>= [8x - 3*√(x^2 + 16)] / [24*√(x^2 + 16)] </span>
<span>At f'(t) = 0 </span>
<span>0 = 8x - 3*√(x^2 + 16) </span>
<span>8x = 3*√(x^2 + 16) </span>
<span>64x^2 = 9(x^2 + 16) </span>
<span>x = 12/√55 x>0 </span>
<span>= 1.618 Km .... distance travelled throgh water </span>
<span>4 - x = 2.382 Km ......distance on foot</span>
