The area of the triangle is 14.1 square meters
How to determine the triangle area?The side lengths are given as:
5m, 6m and 9m
Calculate the semi-perimeter (s) using
s = (5 + 6 + 9)/2
Evaluate
s = 10
The area is then calculated as:
[tex]Area = \sqrt{s(s -a)(s-b)(s-c)[/tex]
This gives
[tex]Area = \sqrt{10 * (10 -5)(10-6)(10-9)[/tex]
Evaluate the products
[tex]Area = \sqrt{200[/tex]
Evaluate the exponent
Area = 14.1
Hence, the area of the triangle is 14.1 square meters

[tex]f'(x) = \frac{4ln {}^{} (x) {}^{3} }{x} [/tex]

A line passes through the point (-2,7) and has a slope of -5. What is the value of a if the point (a,2) is also on the line?
Answer:
a = -1
Step-by-step explanation:
The slope, m from point -2,7 to a,2 has to be -5
m = (y1-y2)/(x1-x2)
-5 = ( 7-2)/(-2 -a) solve for 'a'......cross multiply
10+ 5a = 5

Julián just retired, and has $800,000 to invest. A very safe Certificate of Deposit (CD) account pays 2.5%, while a riskier bond fund pays 5% in interest. Julián figures he needs $36,000 a year in interest to live on. How much should he invest in each account to make enough interest while minimizing his risk?
An equation is formed of two equal expressions. Julian should invest $160,000 in CD and $640,000 in Bond.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the amount invested in CD be represented by x, while the amount invested in bond be represented by y. The total amount that Julian had is,
x + y = 800,000
x = 800,000 - y
The interest that Julian needs in a year is $36,000. Therefore, the total interest should be,
0.025x + 0.05y = 36000
0.025(800,000 - y) + 0.05y = 36000
20,000 - 0.025y + 0.05y =36,000
0.025y = 16,000
y = $640,000
Substitute the value of y
x + y = 800,000
x = $160,000
Hence, Julian should invest $160,000 in CD and $640,000 in Bond.

Un constructor tiene un predio, por lo que está considerando que los terrenos sean rectangulares con un perímetro de 64 metros.
Based on the perimeter of the rectangle, and the adjustments to make the plot a square, the sides are 13m and 19m.
What are the sides of the plot?The perimeter is:
2(L + W) = 64
L + W = 32
The adjustment to make the plot a square would mean that both sides can be equal:
L + 3 = W - 3
L = W - 6
Substituting in the original formula gives:
L + W = 32
W - 6 + W = 32
2W = 38
W = 19 m
L would be:
L + W = 32
L + 19 = 32
L = 13m

First, let's complete the angles in the triangle. Remember that the sum of the angles in a triangle is 180 degrees.
73 + 90 + x = 180
163 + x = 180
x = 17
So, the angle that completes the triangle is 17 degrees. If we look at that angle in the triangle and the one adjacent to it, we can see that those two angles form a linear pair (or are supplementary, both meaning that they add up to 180 degrees).
17 + x = 180
x = 163
So, 17's supplement is 163 degrees. The 163 degree angle corresponds with angle r, and corresponding angles are congruent.
Therefore, angle r is 163 degrees. The correct answer is option C.

What is permutation?A permutation is the arrangement or ordering of a finite set of an element.
From the information given:
If there are 10 homes in the desired price range listed in the area:
Then:
n = 10 and r = 3So, the number of ways of choosing 3 out of 10 (without replacement) and arranging is:
[tex]\mathbf{^nP_r= \dfrac{n!}{(n-r)!}}[/tex]
[tex]\mathbf{^nP_r= \dfrac{10!}{(10-3)!}}[/tex]

Now, the number of ways of choosing 3 out of 10 if the order of visiting is not important is the combination of the elements and it can be computed as:
[tex]\mathbf{^nC_r= \dfrac{n!}{(n-r)!r!}}[/tex]
[tex]\mathbf{^{10}C_3= \dfrac{10!}{(10-3)!3!}}[/tex]

The model for the height of the balloon captured from the ground with a balloon launcher can be represented by the function… how long will it take for the balloon to hit the ground after it’s launched?
Answer:
2 seconds
Step-by-step explanation:
To find the time it takes for the balloon to reach the ground, you need to set the equation equal to 0. This is because the ground technically has a height of 0.
h(t) = -16² + 128t <----- Original expression
0 = -16² + 128t <----- Plug 0 in for h(t)
16² = 128t <----- Add 16² to both sides
256 = 128t <----- Solve 16²
2 = t <----- Divide both sides by 128
Therefore, if t = 2, it will take the balloon 2 seconds to reach the ground.
==========================================================
Explanation:
The balloon is on the ground when the height is zero.
Replace h with 0 and solve for t.
[tex]h(t) = -16t^2 + 128t\\\\0 = -16t^2 + 128t\\\\-16t^2 + 128t = 0\\\\-16t(t - 8) = 0\\\\-16t = 0 \ \text{ or } \ t-8 = 0\\\\t = 0/(-16) \ \text{ or } \ t = 0+8\\\\t = 0 \ \text{ or } \ t = 8\\\\[/tex]
Ignore t = 0 because this is when the balloon is initially on the ground. In other words, the balloon starts on the ground, so it makes sense that t = 0 leads to h = 0.
The other solution t = 8 is what we're after. The balloon touches the ground again at the 8 second mark. This is the length of time the balloon is in the air.
A quick way to determine and confirm the answer is to use graphing software. Check out the diagram below. We have a parabola with x intercepts of 0 and 8.
