The side lengths of the following right triangle 15,20 and 25, as shown below. The altitude from the right angle splits the hypotenuse into line segments of length x and y. Solve for h,x, and y.
Answers
Answer:
[tex]h = 12[/tex]
[tex]x = 9[/tex]
[tex]y= 16[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find h, x and y
Let the base of the triangle be 15.
So, the area is:
[tex]A = \frac{1}{2} * 15 * 20[/tex]
[tex]i.e\ height = 20[/tex]
[tex]A = \frac{1}{2} * 300[/tex]
[tex]A = 150[/tex]
Let the base of the triangle be 25.
So, the area is:
[tex]A = \frac{1}{2} * 25 * h[/tex]
[tex]i.e\ height = h[/tex]
[tex]A = \frac{1}{2} * 25h[/tex]
Substitute [tex]A = 150[/tex]
[tex]\frac{1}{2}*25h = 150[/tex]
Solve for h
[tex]h = \frac{150 *2}{25}[/tex]
[tex]h = 6 *2[/tex]
[tex]h = 12[/tex]
Considering the smallest triangle
[tex]Hypotenuse = 15[/tex]
So:
[tex]15^2 = h^2 + x^2[/tex]
[tex]15^2 = 12^2 + x^2[/tex]
This gives:
[tex]15^2 - 12^2 = x^2[/tex]
[tex]81 = x^2[/tex]
Take square roots
[tex]9 =x[/tex]
[tex]x = 9[/tex]
Solving for y
[tex]x + y = 25[/tex]
[tex]y= 25 - x[/tex]
[tex]y= 25 - 9[/tex]
[tex]y= 16[/tex]

We can split up this 3D composite figure into two main parts (as shown in the picture I attached), and find each part’s volume before adding them together for the total volume.
Cube —> 5x5x5 —> 25x5 = 125 in^3
Rectangular Prism —> 20x5x5 —> 100x5 = 500 in^3
125 + 500 = 625
So the answer is A. 625 in^3

Please Help! After one side of a square flower bed was enlarged by 2 ft and the other side was enlarged by 3 ft, the area of a new flower bed became twice the area of an old one. How long was the side of the old flower bed?
Answers
The problem says we have a square flower bed to start out with.
Let's have the sides of the squares be "x". The area of this original flower bed is [tex]x^{2}[/tex].
Then, one side of the square is enlarged by 2ft, and another side 3ft. Our new flower bed dimensions are now (x+2) and (x+3). Multiply (x+2) and (x+3) to find the area, which gets you [tex]5x^{2} +6x+6[/tex].
We also know that the new area of the flower bed is twice the size of the original flower bed. Multiply the original area by 2, you get [tex]2x^{2}[/tex].
With the new area and the doubled original area, we can now make an equation: [tex]5x^{2} +6x+6=2x^{2}[/tex]
Solve for x, you get 6.
Hope this explanation helped, maybe a bit too many details but there's your answer, 6!
The side length of the original bed is 6 units
Area of squareThe formula for finding the area of the square is expressed as:
A = x^2
If one side of a square flower bed was enlarged by 2 ft and the other side was enlarged by 3 ft, the area of the bed becomes;
A = (x+2)(x+3)
A = x^2 + 5x + 6
If the area of a new flower bed became twice the area of an old one, then;
5x^2 + 6x + 6 = 2x^2
On factorizing, the value of x is 6 which shows that the side length of the original bed is 6 units

A town has a fireworks display, where fireworks are set off from a bridge over a lake. The function h (t) = -16t2 + 150t + 10.5 represents
the approximate height of each firework, in feet, t seconds after it is launched.
Approximately when do the fireworks reach their maximum height?
Answers
Answer:
h(t) = 4.68 seconds
Step-by-step explanation:
The function that represents the height of each firework in feet is :
[tex]h (t) = -16t^2 + 150t + 10.5[/tex] .....(1)
We need to find the time the fireworks take to reach their maximum height. For maximum height,
dh/dt = 0
So,
[tex]\dfrac{d}{dt}(-16t^2 + 150t + 10.5 )=0\\\\-32t+150=0\\\\t=\dfrac{150}{32}\\\\t=4.68\ s[/tex]
Put t = 4.68 in equation (1).
[tex]h (t) = -16(4.68)^2 + 150(4.68)+ 10.5\\\\h(t)=362.06\ text{feet}[/tex]
So, the fireworks will take 4.68 seconds to their maximum height.
