P²=H²-B²P²=9²-2²P²=81-4P²=77P=√77Option D
Answer:
[tex]\sf D) \sqrt{77} \: ft [/tex]
Step-by-step explanation:
Given that,
→ Perpendicular (x) = ?
→ Hypotenuse (h) = 9 feet
→ Base (b) = 2 feet
Now by using the Phythagoras theorem,
→ (Hypotenuse)² = (Perpendicular)² + (Base)²
→ (h)² = (x)² + (b)²
→ (9)² = (x)² + (2)²
→ 81 = (x)² + 4
→ (x)² = 81 - 4
→ (x)² = 77
→ [ x = √(77) ]
Thus, length of remaining side is √(77) ft.
Which expression is equivalent to n5 • k5 • n-5 • k?
a. N^5 k
b. N^-25 k^5
c. K^6
d. (nk)^6
The expressions are algebraic expressions, and the equivalent expression of n⁵ * k * n⁻⁵ * k is k⁶
How to determine the equivalent expression?The expression is given as:
n⁵ * k⁵ * n⁻⁵ * k
Rewrite the expression as:
n⁵ * k * n⁻⁵ * k = n⁵ * n⁻⁵ * k⁵ * k
Apply the law of indices

Explain how you can know whether a system of linear equations will have infinite solutions.
Answer
If the y-intercept and slope of two lines are the same, they are on the same precise line. To put it another way, if the two lines are the same line, the system should have an endless number of solutions.

If x =3+2 root 2 find x - 1/x
Answer:
-2+2[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Since we have the value of x, 3+2[tex]\sqrt{2}[/tex], we can plug that value into the new equation.
We would recieve (3+2[tex]\sqrt{2}[/tex]-1)/3+2[tex]\sqrt{2}[/tex]
Which could simplify to -2+2[tex]\sqrt{2}[/tex]
[tex]x-\dfrac 1x\\\\\\=3+2\sqrt 2- \dfrac 1{3+2\sqrt 2}\\\\\\=3+2\sqrt 2 - \dfrac{3-2\sqrt2}{\left(3+2\sqrt 2\right) \left(3-2\sqrt 2 \right)}\\\\\\=3+2\sqrt 2 -\dfrac{3-2\sqrt 2}{3^2 - \left(2\sqrt 2 \right)^2}\\ \\\\=3+2\sqrt 2-\dfrac{3-2\sqrt2}{9-8}\\\\\\=3+2\sqrt 2-3+2\sqrt 2\\\\\\=4\sqrt2[/tex]

Answer:
[tex]\frac{2x}{x+5}[/tex]
Step-by-step explanation:
We are given a function for f and g, and are asked to find f/g.
We know f = 4x^2 + 6x and g = 2x^2 + 13x + 15
Simply put function of f over g.
[tex]\frac{4x^2+6x}{2x^2+13x+15}[/tex]
Factor:
[tex]\frac{2x(2x+3)}{(2x+3)(x+5)}[/tex]
Since both numerator and denominator have 2x + 3, we can cancel them out.
[tex]\frac{2x}{x+5}[/tex] is our answer.

(20 POINTS AND BRAINLIEST) What is the area of the shaded region?
Type only the numeric answer
Answer:
59 square inches.
Step-by-step explanation:
Equation for area of whole, large triangle:
A = 1/2(b)(h)
A = 1/2(13)(14)
A = 91 square inches
Equation for area of tiny, white triangle:
A = 1/2(b)(h)
A = 1/2(8)(8)
A = 32 square inches
Equation to find the area of the shaded region:
A = 91 - 32
A = 59 square inches
Answer:
64
Step-by-step explanation:
It's 64 because the area is the inside and 8 x 8 = 64.

Second condition
Perimeter = 2 (l + b)
80 = 2 (x + y)
x + y = 40 -------------(2)
To find area,

Question 2 (5 points)

What is the equation of the line that passes through the points (-2, 3) and (2, 7)? (5 points)
оа
x-y=-1
Ob
X-y=-2
Ос
x - y = -5
Od
X-y= -6
Answer:
[tex]x - y + 5 = 0[/tex]
Step-by-step explanation:
Given:
Line passes through (-2,3) and (2,7)Required:
Find the equation of the lineThe equation of the line passing through two points is given by
[tex]\frac{y-y_{1} }{y_{2}- y_{1} } =\frac{x_{}- x_{1} }{x_{2} -x_{1} }[/tex]
So, [tex]\frac{y-3}{7-3} =\frac{x-(-2))}{2-(-2)}[/tex]
[tex]\frac{y-3}{4} =\frac{x+2}{2+2}[/tex]
[tex]\frac{y-3}{4} =\frac{x+2}{4}[/tex]
Now, [tex]y-3 = x+2[/tex]
On rearranging,
[tex]x - y + 3 + 2 = 0x - y + 5 = 0[/tex]
Therefore, the equation of the line is [tex]x - y + 5 = 0.[/tex]

Find the diameter of the circle with the given circumference. Use 3.14 for pi . C=18 cm
Answer:
[tex]d=\frac{18}{\pi }[/tex]
Step-by-step explanation:
We work our way backward to find the diameter.
Circumference of a Circle Formula:
[tex]C=2\pi r[/tex]
r is radius , 2*radius = diameter.
Given information: C=18 cm , pi=3.14.
[tex]C=2\pi r\\18=2\pi r\\[/tex]
Get r by itself.
[tex]r=18/2\pi\\r=9/\pi[/tex]
r≈2.864788976
2*r=d
[tex]2*9/\pi =diameter\\d=\frac{18}{\pi }[/tex]
Find the median, first quartile, third quartile, and interquartile range of the data.
40,33,37,54,41,34,27,39,35
??????? I haven't heard this before
Answer:
Median: 37
First quartile: 33.5
Third quartile: 40.5
Interquartile range: 7
Step-by-step explanation:
Your first step should be putting them in order from least to greatest.
27, 33, 34, 35, 37, 39, 40, 41, and 54. Now to find the median you have to find the middle which in the case would be 37. Now to find the 1st quartile u eliminate the meduan and focus on the lower half of the numbers which would be 27, 33, 34, and 35. If you numbers are even you add and divide by 2. In this case you have to add 34 and 33 and then divide by 2 since they are both in the middle. Your 1st quartile would be 33.5. To find the 3rd quartile you do the same thing as the 1st quartile. Only focus on the upper half now. add both the middles then divide by 2 since there are 2 middles. You 3rd quartile should be 40.5. To fine the inerquartile range you subtract the 1st quartile from the 3rd. so it would be 40.5-33.5 which would give you 7. If you want to fine just the range you would subtract the highest number from the lowest number.
