Find the volume of a prism that is 5 m long, 40 cm wide, and 2500 mm high.
san4es73 [151]

Answer:

5.0 m^3

Step-by-step explanation:

The volume of a rectangular  prism is given as:

V = L * W * H

where L = length

W = width

H = height

Put all the dimensions in the same unit, metre (m).

Length = 5 m

Width = 40 cm = 40 / 100 = 0.4 m

Height = 2500 mm = 2500/1000 = 2.5 m

The volume of the prism is:

V = 5 * 0.4 * 2.5 = 5.0 m^3

Desde la cuspide de un faro de 50m de altura sobre el nivel del mar se observa que el angulo depersion a un bote velero es de 20
poizon [28]

Answer:

137.4 meters

Step-by-step explanation:

In this case, they give us the height of the lighthouse that corresponds to 50 meters and the depression angle is 20 °, in this case we can apply the tangent trigonometric function, which relates the opposite side to the adjacent side.

tan a ° = opposite / adjacent

the horizontal that is formed would be the adjacent side, therefore if we solve we are left with:

horizontal distance = opposite / tan to °

replacing, we are left with:

hd = 50 / tan 20 °

hd = 50 / 0.3639

hd = 137.4

the horizontal distance is equal to 137.4 meters

So totally confused please help
OLga [1]

Answer:

The answer to your question is: r = 0.1

Step-by-step explanation:

Data

P = $4500

A = $9000

t = 9 years

r = rate

Formula

                            r = \sqrt[t]{\frac{A}{P}} - 1\\

Substitution

                             r = \sqrt[9]{\frac{9000}{4500} - 1\\

Simplification

                             r = \sqrt[9]{2} - 1

Result

                             r = 1.08 - 1

                             r = 0.08 ≈ 0.1

Look at the graph shown:
lidiya [134]

Answer:

y = 3x - 1

Step-by-step explanation:

Although the coordinate plane is not given, we don't need it to find the solution. We have given all the conditions enough for the solution.

The y-intercept is (-1) and the function passes through the point ( 1, 2 ).

Only the function y = 3x -1 matches these conditions.

We can observe the points in the attached graph.
