How far above ground is the flag pole in inches? Round to nearest inch if needed

Answer:

Step-by-step explanation:

You'll use similar triangles to solve this. Set up 2 ratios as a proportion. First, however, you have to convert the 15 inches to feet. If everything else is in feet, then EVERYTHING has to be in feet. 15 inches is equal to 1.25 feet. Now for the equation:

$\frac{3}{x} =\frac{1.25}{6}$

The first fraction is made up of the heights, 3 being the height of the plumb bob and x being our unknown height of the flagpole; the second fraction is made up of the distances on the ground. Cross multiply to solve:

1.25x = 18 so

x = 14.4 feet, or 14 feet, 4.8 inches

What is the surface area of the prism WILL MARK BRAINLEST WORTH 69 POINTS

marshall27 [118]

Answer:

Surface area of the rectangular prism = $234\,mm^2$

Step-by-step explanation:

The surface area of the rectangular prism is:

$=2((Length\times Width)+(Width\times Height)+ (Height\times Length))$

$Length=15\,mm\\ \\Width=3\,mm\\\\Height=4\,mm$

Area is:

$=2((15\times 3)+(3\times 4)+ (4\times 15))\\\\=2(45+12+60)\\\\=2(117)\\\\=234\,mm^2$

Surface area of the rectangular prism is: $234\,mm^2$

Find the particular solution that satifies the differential equation and the initial condition. f"(x) = x2 f'(0) = 8, f(0) = 4

viva [34]

Answer:

f(x) = x^4/12 + 8x + 4

Step-by-step explanation:

f"(x) = x^2

Integrate both sides with respect to x

f'(x) = ∫ x^2 dx

= (x^2+1)/2+1

= (x^3)/3 + C

f(0) = 8

Put X = 0

f'(0) = 0+ C

8 = 0 + C

C= 8

f'(x) = x^3/3 + 8

Integrate f(x) again with respect to x

f(x) = ∫ (x^3 / 3 ) +8 dx

= ∫ x^3 / 3 dx + ∫8dx

= x^(3+1) / 3(3+1) + 8x + D

= x^4/12 + 8x + D

f(0) = 4

Put X = 0

f(0) = 0 + 0 + D

4 = D

Therefore

f(x) = x^4 /12 + 8x + 4
