A tree casts a shadow of 20 meters when the angle of elevation of the sun is 24°
Find the height of the tree to the nearest meter.
The height of the tree is 9 meters
What is angle of elevation?This is the angle the line of sight makes with the horizontal.
Analysis:
The line of sight , the shadow length and height of tree form right angled triangle.
Let the height of tree be h
so that, tan 24 = h/20
h = 20 tan 24
h = 20(0.445) = 8.9m = 9m
In conclusion, the height of the tree is 9m.

Marco's living room is 4 meters wide and 6 meters long. He wants to install white carpet that costs $8.91 per square meter. How much will it cost to buy enough carpet for the living room?
Answer:
$213.84
Step-by-step explanation:
Think of a rectangle. In the case the length is 6 meters and the width is for meters. To be able to find the area of this rectangle, you need to multiply the length by the width. 6 multiplied by 4 is 24. In the equation it tells you that 1 square meter is $8.91, so now you are trying to figure how much 24 square meters would cost. To figure this out, you will need to multiple 24 by $8.91 giving you $213.84.

Find the x-intercepts of the parabola with
vertex (-3,405) and y-intercept (0,360).
Write your answer in this form: (X₁,Y₁), (X2,₂).
If necessary, round to the nearest hundredth.
Enter the correct answer.
Answer: (-12, 0) and (6, 0)
Step-by-step explanation:
The equation of the parabola is of the form
[tex]y=a(x+3)^2 + 405[/tex]. To find a, we can substitute in the coordinates (0,360).
[tex]360=a(0+3)^2 + 405\\\\360=9a+405\\\\-45=9a\\\\a=-5[/tex]
So, the equation is [tex]y=-5(x+3)^2 + 405[/tex]. Setting this equal to 0,
[tex]-5(x+3)^2 + 405=0\\\\5(x+3)^2 = 405\\\\(x+3)^2 = 81\\x+3=\pm 9\\\\x=-12, 6[/tex]
So, the x-intercepts are (-12, 0) and (6, 0).

The ratio of the one leg of
the right triangle to the other
leg of the right triangle must
be 8:7. Determine the
greatest length of one leg of
the right triangle given the
other leg of the right triangle
is 10.5 feet.
Answer:
12 ft
Step-by-step explanation:
We assume right triangle ABC with the right angle being at B. We are given that the ratio of AB/CB = 8/7, and one leg is 10.5. Let's call the other leg is X. We don't know which leg is which so assume both. Then
(a) assume the X leg is the longer
8 / 7 = X / 10.5
(8 * 10.5) / 7= X
X = 12
OR (b) assume the X leg is the shorter
8/7 = 10.5 / X
(8X / 7) = 10.5
8X = 10.5 * 7
8X = 73.5
X = 9.1875
(a) is the greater so (a) wins

The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side. The correct option is C.
What is the triangle inequality theorem?The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.
Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,
[tex](a+b) > c\\(b+c) > a\\(c+a) > b[/tex]
Given the length of the two sides of the triangle, therefore, we can write the inequalities,
8 + 5 > x ⇒ 13 > x
8 + x > 5 ⇒ x > - 3
5 + x > 8 ⇒ x > 3
Now, as per the inequality the value of x can lie between 3 to 13, but as the side needs to be greatest, therefore, the value of x will be 12.
Hence, the correct option is C.

What is the solution to this matrix equation?
By using a system of equations, we will see that the solution is:
x = 25, y = -50, z = -15
How to solve the matrix equation?We can write this as a system of equations:
4x + 2y - z = 15
x + y - z = -10
-3x - y + z = 60
Notice that if we add the second and third equations, we get:
(x + y - z) + (-3x - y + z ) = -10 + 60
-2x = 50
x = 50/-2 = -25
So we already got the value of x. Replacing that in the second equation we et:
25 + y - z = -10
Isolating y we get:
y = -10 - 25 + z = z - 35
Now we can replace that in the first equation:
4x + 2y - z = 15
4*25 + 2*(z - 35) - z = 15
100 + z - 70 = 15
z = 15 - 100 + 70 = -15
And using:
y = z - 35 = -15 - 35 = -50
Then the soution to the matrix equation is:
x = 25, y = -50, z = -15

what is the meaning of Interest rate
Answer:
Interest rate is a proportion of a loan rewarded as interest to the borrower, usually expressed as an annual percent of the current loan.
Answer:
See below
Step-by-step explanation:
An interest rate is basically a percentage of principal charged by the lender for the use of its money, and it is paid via simple interest (usually in an annual period). That principal is the amount of money loaned.
For example, you may have seen a 1.5% annual interest rate, or something like that. This means that if your principal was $5000, let's say, you would have to pay $5000 * 0.015 = $75 in interest per year.
