A square pool has an area of 169ft^2 . What is the side length of the pool?
Area of a square is side ^2
To find the length of the side using area find the square root of the area.
Side length = sqrt(169)
Side length = 13 feet
Answer:
13 ft
Step-by-step explanation:
The area of a pool is length × width (l × w) , but the length and width are the same so I'll use [tex]b[/tex] representing both length and width:
A = l × w
A = [tex]b^{2}[/tex]
Area of the pool is 169
169 = [tex]b^{2}[/tex]
[tex]b[/tex] = [tex]\sqrt{169}[/tex]
[tex]b[/tex] = 13

Find the measure of GH given that HI = x + 2, GI = 4x - 6, and GH = x + 3.
Answer:
8.5
Step-by-step explanation:
x+3+x+2=4x-2
2x+5=4x-6
2x-4x=-6-5
-2x=-11
x=5.5
GH=(5.5)+3
=8.5
The measure of GH is 7/4.
What is a line segment?A line segment is a part of line that is bounded by two distinct end-points. A line segment has a fixed length. Figures such as a triangle, polygon, hexagon, square are made of different numbers of line segments.
For the given situation,
The lengths of HI = x+2, GI = 4x-6, GH = x+3.
Thus the measure of GH is
[tex]x+3=(x+2)+(4x-6)[/tex]
⇒ [tex]x+3=x+2+4x-6[/tex]
⇒ [tex]x+3=5x-4[/tex]
⇒ [tex]5x-4-x-3=0[/tex]
⇒ [tex]4x-7=0[/tex]
⇒ [tex]4x=7[/tex]
⇒ [tex]x=\frac{7}{4}[/tex]
Hence we can conclude that the measure of GH is 7/4.

x^4-13x^2+36=0 x=???
Answer:
-3,-2,3,2
Step-by-step explanation:
Let a = x^2
Then the equation turns into
a^2 - 13 a + 36 =0
a^2 - 4a - 9a + 36 = 0
a(a - 4) -9 (a -4) =0
(a-9)(a-4) = 0
a = 9 or a = 4
So
x^2 = 9 or x^2 = 4
Therefore x = -3,3 or x= -2,2.
x⁴ - 13x² + 36 = 0
t² - 13t + 36 = 0
t = 4, t = 9
x² = 4, x² = 9
x = ±2, x = ±3

There's a roughly linear relationship between the length of someone's femur (the long leg-bone in your thigh) and their expected height. Within a certain population, this relationship can be expressed using the formula h=2.35f+54.7h, where h represents the expected height in centimeters and ff represents the length of the femur in centimeters. What is the meaning of the ff-value when h=149h
Answer:
The desired value of [tex]f=-0.0002937[/tex]
Step-by-step explanation:
The relationship between [tex]h[/tex] and [tex]f[/tex] is given as,
[tex]h=2.35f+54.7h[/tex]
Here, [tex]h[/tex] represents the expected height in centimeters, and [tex]f[/tex] represents the length of the femur in centimeters.
The meaning of [tex]f[/tex] value when [tex]h=149h[/tex]
For obtaining the result for the above condition, substitute [tex]h=149h[/tex] in the relation function between [tex]h[/tex] and [tex]f[/tex].
Therefore,
[tex]\begin{aligned}149h&=2.35f+54.7(149h)\\-8001.3h&=2.35f\\f&=-0.0002937\end{aligned}[/tex]
