The bottom edge of a 16-foot long cantilever is given by the equation y = 2Vx, where y is the distance the
bottom edge is from ground height, in feet.
y
(a) What is the value of b, the height of the
cantilever, in feet?
b
T
y=2&x
b) To the nearest tenth of a foot, what is the
thickness, T, of the cantilever at x =6 feet?
Answer:
[tex](a)\ b = 8[/tex]
[tex](b)\ T = 3.1[/tex]
Step-by-step explanation:
Given
[tex]y = 2\sqrt x[/tex]
See attachment
Solving (a): Find b
At point b, [tex]x = 16[/tex]
So, the value of b is:
[tex]b = 2 * \sqrt{16[/tex]
[tex]b = 2 * 4[/tex]
[tex]b = 8[/tex]
Solving (b): Find T
First, we calculate the value of y at point T
[tex]y = 2\sqrt x[/tex]
At point T, [tex]x = 6[/tex]
So:
[tex]y = 2 * \sqrt 6[/tex]
[tex]y = 2 * 2.45[/tex]
[tex]y = 4.9[/tex]
To calculate T, we subtract the calculated height (y) from the value of b
[tex]T =b - y[/tex]
[tex]T = 8 - 4.9[/tex]
[tex]T = 3.1[/tex]
What is the measure of the internal angle H' of the image in degrees
Answer:
40 degrees
Step-by-step explanation:
- All internal angles of a triangle add up to 180 degrees.
- A right angle is 90 degrees.
90+50=140
subtract 140 from 180, which is 40 degrees.

what is the value of 6(2b-4) when b+5?
Answer:
The value of 6(2b-4) is 36.
Step-by-step explanation:
Given expression: 6(2b-4)
To find the value of 6(2b-4) at b=5, we need to substitute the b=5 in the expression, we get
6(2(5)-4)
= 6(10-4)
=6(6)
= 6x6=36
⇒ 6(2(5)-4)=36
Answer:
The value of 6(2b-4) when b=5 is 36.
Step-by-step explanation:
Given expression: 6(2b-4). To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get….Therefore, the value of 6(2b-4) is 36, when b=5.

Bob can paint a fence in 12 hours, and working with Jen can paint a fence in 4 hours. How long would it have taken Jen to paint the fence alone?
Answer:
6 hours
Step-by-step explanation:
For Bob
12 hours = 1 fence
1 hour = 1/12 fence
Together Bob and Jen
4 hours = 1 fence
1 hour = 1/4 fence
Now, for Jen:
1 hour = 1/4 - 1/12= 3/12 - 1/12 = 2/12=1/6
Find the amount of time Jen will need:
1/6 fence = 1 hour
1 fence = 6 hour

Solve for x
triangle abc is similar to triangle aed
Answer:
9/5 or 1.8
Step-by-step explanation:
triangle aed is larger than triangle abc by a scale factor of 5; we know this because side ed is 5 units and cb, the corresponding side in triangle abc, is 1. if ad has a length of 9, the length of ab must be 9 divided by five. thus, z is equal to 9/5 or 1.8.

Answer:
y - 20 = (-1/5)(x - 5)
Step-by-step explanation:
The slope of the given line is 5. The slope of any line perpendicular to the given line is the negative reciprocal of the given slope:
Slope of perpendicular line here is -1/5.
We use the point-slope formula as a framework here:
y - 20 = (-1/5)(x - 5)

A sequence defined by the rule f(n)=4f(n-1)+2.if f(1)=3 then find f(4)=?
Answer:
f(4) = 6
Step-by-step explanation:
Given the rule f(n) = 4f (n - 1) + 2 where f(1) = 3, f(n) is just a fancy way to name the variable y. As you've seen before, there are equations that are usually y equals x and something. For example:
y = mx + b
is the same thing as
f(n) = y = mn + b.
It might be that you have multiple of the same equation where f(n) and f(x) have two different outcomes.
The f(n) part (bolded) is the "x variable" in this equation. So in f(1), n = 1.
f(n) = 4f (n - 1) + 2
f(n) = (4fn - 4f) + 2
f(n) = (n) + 2
f(1) = 1 +2
3 = 3
Now do the same thing for f(4):
f(n) = 4f (n - 1) + 2
f(n) = (4fn - 4f) + 2
f(n) = (n) + 2
f(4) = 4 + 2
f(4) = 6
In the quadratic equation x2 - 8x + a = 0; what is the value, a, in order to form a perfect square?
Answer:
16
Step-by-step explanation:
(x - y)² = x² - 2xy + y²
x = x and y = a
2xy = 8x
2*x*a = 8x
a = [tex]\frac{8x}{2x}[/tex]
a = 4
a² = 16
