We know the are of a square is equal to s^2, where s is the side length.
While the are of a right angle tringle is 1/2*base*height
Then we have,
s = 10
base = 4
height = 4
(area of square) - (area of triangle)
=> (10^2) - (1/2)(4)(4)
=> 100 - 8
=> 92
Finally we get: 92 in^2

Which of the following represents the factorization of the trinomial below?
-3x²-18x²-24x
Answers
The following represents the factorization of the trinomial is -3x [ (x+2)(x+4)].
What is Trinomial?
A trinomial is a polynomial consisting of three terms or monomials.
Given polynomial:
-3x³-18x²-24x
Taking -3x as common, we get
=-3x(x²+6x+8)
Now, by factorization
=-3x (x²+4x+2x+8)
= -3x[x(x+4) + 2(x+4)]
= -3x [ (x+2)(x+4)]
Hence, the factorization is -3x [ (x+2)(x+4)].

Step-by-step explanation:
A vertical angle is formed from the rays that are opposite the rays that form the original angle.
__
opposite raysThe rays forming angle CXD are rays XC and XD. The ray opposite XC will have end point X, and can be named by either of the two points shown on the ray: A or P. That is, rays XA and XP are opposite ray XC.
Similarly, rays XB and XQ are opposite ray XD.
vertical angleThe vertical angle can be named using either of the first pair of opposite rays with either of the second pair:
∠AXB, ∠PXB, ∠AXQ, ∠PXQ
Of course, the ray names can be reversed in the angle names:
∠BXA, ∠BXP, ∠QXA, ∠QXP
Altogether, there are 8 ways to name the vertical angle to ∠CXD.

So far so good right? Well, IF these triangles are similar, that means that angle X must correspond to angle A. Since corresponding angles of similar triangles are equal to each other, lets check of angle X is equal to angle A.
Angle X = 29 degrees
Angle A = 28 degrees
28 does not equal 29 degrees. Therefore, the triangles are not similar. If angles X and A were equal, than the triangles would have been similar due to the Side-Angle-Side rule (SAS).

The time in seconds, t, it takes for a specific object being dropped from a particular height in feet above sea level, h, to reach the ground can be found by the radical function t equals one fourth times radical h period At what height should you drop an object in order for it to reach the ground in 16 seconds?
Answers
Answer:
B.) 4,096 feet
Step-by-step explanation:
You were given a time, and time in the equation is represented by "t". To find the height, represented by "h", you just need to plug the given value in for "t" and simplify to find "h".
t = (1/4)√x <--- Original equation
16 = (1/4)√x <--- Plug 16 in "t"
64 = √x <--- Divide both sides by (1/4)
4,096 ft = x <--- Square both sides
The object reach the ground in 16 seconds, you should drop it from a height of 4096 feet.
The equation is t=1/4 √x , where t is time in seconds and x is height in feet. To determine the height x at which an object should be dropped to reach the ground in 16 seconds, you can plug in the value of t=16 into the equation:
16 = 1/4 √x
Simplify the equation by multiplying both sides by 4:
4⋅16= √x
64= √x
Now, square both sides to isolate x:
64²=x
4096 = x
Therefore, to have the object reach the ground in 16 seconds, you should drop it from a height of 4096 feet.

Question 7:
g is 60% of h
f is a third of g
Write the ratio f g h in its simplest form.
Answers
The ratio of f to g to h is:
1:3:5
How to write the ratio?
First, we know that g is the 60% of h, then we can write:
g = 0.6*h
Now we can write the 0.6 as a fraction, then 0.6 = 3/5.
g = (3/5)*h
So we can write:
5*g = 3*h
So the ratio of g to h is 3:5
Now, we know that f is a third of g:
f = (1/3)*g
3f = g
So the ratio of f to g is:
1:3
notice that the value that represents the proportion of g is 3 in both ratios, so we can just write:

Answers
Using compound interest, it is found that Dante was 6.6 years old when the balance in the account reached $13,000.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.In this problem, we have that the parameters are given as follows:
A(t) = 13000, A(0) = 10000, r = 0.04, n = 12.
Hence the time in years is found as follows:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]13000 = 10000\left(1 + \frac{0.04}{12}\right)^{12t}[/tex]
[tex](1.0033)^{12t} = 1.3[/tex]
[tex]\log{(1.0033)^{12t}} = \log{1.3}[/tex]
[tex]12t\log{1.0033} = \log{1.3}[/tex]

General Sherman, a tree located in Sequoia National Park, stands 275 feet tall. To see the top of the tree,
Carlos looks up at a 19° angle of elevation. If Carlos is 6 feet tall, how far is he from the base of the tree to the
nearest foot?
Answers
By using trigonometric relations, we will see that the distance between Carlos and the tree is:
D = 781.23 ft
How far is Carlos for the base of the tree?We can model this with a right triangle. We know that Carlos is 6ft tall, and the height of the tree is 275ft.
Then one of the cathetus of the triangle is equal to:
275ft - 6ft = 269ft.
That cathetus is the opposite cathetus to the angle of 19° (the elevation angle). And the adjacent cathetus is the distance between Carlos and the tree.
Then we can use the relation:
tan(a) = (opposite cathetus)/(adjacent cathetus).
Where:
a = 19°opposite cathetus = 269ftadjacent cathetus = D.Replacing that, we get:
tan(19°) = 269ft/D
Solving for D, we get:
D = 269ft/tan(19°) = 781.2ft
So we conclude that Carlos is at 781.23 ft of the tree.
