Calculate the compound interest.

Mathematics

You use the first formula. You plug in the values to get A=400(1+(0.05/1))^6. You should get approximately $536.04. I used 0.05 because you need to change the percent to a decimal, and 1 for n because it is compounded annually, meaning once a year.

Estimate the height of a tree using the following measurements:height of the rod:180 cm,length of the shadow of the rod is 116 c
andriy [413]

Answer:

1303.45 cm

Step-by-step explanation:

The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.

Let x be the height of the tree. Setting the ratios equal, we get:

180/116 = x/840

Solve for x:

x = 840 * (180/116)

x ≈ 1303.45 cm

Using the slope​ formula, find the slope of the line through the given points.
UNO [17]

Answer:

0

  = (-5--5)/ (9--8)

 = (-5+5)/(9+8)

The slope it 0

This is a horizontal line because the y value doesn't change.  If the y value doesn't change, the slope it zero.
