A tree 8 m tall casts a shadow 15 m long on the ground. Find the distance between

Mathematics

Answer:

The distance from the top of the tree to the end of its shadow is 17 m ⇒ 4th answer

Step-by-step explanation:

The relation between the three sides a, b and c of a right triangle, where c is the hypotenuse and b , c are the legs of the right angle is:

c² = a² + b² ⇒ Pythagoras Theorem

The tall of the tree (T) and its shadow in the ground (S) form two legs of a right triangle and the distance from the top of the tree to the end of the shadow (D) formed the hypotenuse of the triangle

By using Pythagoras Theorem

∵ (D)² = (T)² + (S)²

∵ The tree is 8 m tall

∴ T = 8

∵ It casts a shadow 15 m long on the ground

∴ S = 15

- Substitute them in the formula above

∴ (D)² = (8)² + (15)²

∴ (D)² = 64 + 225

∴ (D)² = 289

- Take √  for both sides

∴ D = 17

The distance from the top of the tree to the end of its shadow is 17 m

kherson [118]

Answer:

A

Step-by-step explanation:

Just put x = 80 and y = 210 into the equation...

or put x = 40, y = 90.

A:

210 - 90 = 3(80-40)

120 = 120√

B:

210 + 90 = 3(80+40)

300 = 360×

C:

210 - 90 = 2.6(80-40)

120 = 104×

D:

210 + 90 = 2.6(80+40)

300 = 312×

HIJK is a rectangle. Find the value of x and find the length of each diagonals. If hj=19+2x and ik=3x+22
viva [34]
Hj  and ik are  opposite sides of the rectangle so they areequal in length.

19 + 2x = 3x + 22
19-22 = 3x-2x
x = -3 

We can't find the length of the diagonals as we have no information about the width.

the logarmithmic functions, f(x)=logx and g(x), are shown on the graph. what is the equation that represents g(x)? explain.​
mestny [16]

Answer:

g(x) = log(x+1) + 4

Step-by-step explanation:

If a curve has been translated (shifted or slid) you can add to or subtract from the x to show horizontal (left or right) shifts and add or subtract a number tacked onto the end of the equation to cause the vertical shift (up or down).

The curve for g(x) is shifted left 1 unit. So change the x to x+1. Left and right shifts are a little backwards from what you might think. But left shift is a +1.

Vertical shifts adjust the way you would think they should. UP shift 4 units is a +4 on the end of the equation. See image.
