Answer:
(2x-5)(2x-5), 81 meters
Step-by-step explanation:
All of the sides of a square are equal, so to find the area we need to multiply 2x-5 by 2x-5: (2x-5)(2x-5)
Using this equation we can plug in 7 for x:
(2(7)-5)(2(7)-5) =
(14-5)(14-5) =

How to find the equation of the line for the height of a triangle
In this question we must find the equation of the line perpendicular to the segment BC and that goes through the point A(x, y) = (1, 3). First, the slope of the line segment BC is:
m = [1 - (- 3)]/[5 - (- 3)]
m = 4/8
m = 1/2
And the slope of the line is:
m' = - 1/(1/2) = - 2
The intercept of the line is found by using the explicit form of equation of the line, m' = - 2 and (x, y) = (1, 3):
3 = - 2 · 1 + b
b = 5
The equation of the line in explicit form is y = - 2 · x + 5, whose implicit form is 2 · x + y = 5. (Correct choice: D)

Circle S is shown. Line segment R T is a diameter. The length of S T is 4. Sector R S T is shaded.
The measure of central angle RST is radians.
What is the area of the shaded sector?
4Pi units squared
8Pi units squared
16Pi units squared
20Pi units squared
The area of the sector in radians is calculated as: B. 8π units squared.
What is the Area of a Shaded Sector?The area of a sector where the central angle of the sector that is shaded in a circle is given in radians is calculated using the formula that is expressed as:
Area of sector = (1/2) × r²θ; where we have:
θ = the angle subtended at the center/central angle measure in radians
r = the radius of the circle
Given the following:
The shaded area is half of the circle. Its measure would be 180 degrees which when expressed in radians would be π.
Central angle measure in radians (θ) = π
Radius (r) = 4 units
Plug in the values into the area of sector formula
Area of sector = (1/2) × r²θ = (1/2) × (4²)(π)
Area of sector = (1/2) × (16)(π)
Area of sector = (1 × 16 × π)(2)
Area of sector = (16π)(2)
Area of sector = 8π units squared
In conclusion, the area of the shaded sector in the image given below is calculated as: B. 8π units squared.

Circadian rhythms are biological processes that oscillate with a period of approximately 24 hours. That is, a circadian rhythm is an internal daily biological clock. Blood pressure appears to follow such a rhythm. For a certain individual the average resting blood pressure varies from a maximum of 100 mmHg at 2:00 P.M. to a minimum of 80 mmHg at 2:00 A.M.
Find a sine function of the form f(t) = a sin(ω(t − c)) + b
that models the blood pressure at time t, measured in hours from midnight.
The equation becomes of the pressure is P = 90 + 10 sin(π/36(t +4 ))
By observation the sine function should be of form P= 90 + 10 sin(ω(t − c)) as it oscillates about 90 and with a factor of 10. Let time be represented by the variable t in hours from 12.00 AM.
At 2:00 P.M. that is t= 14 hours the pressure is 100 mmHg
Substituting it in the equation we get,
100 = 90 + 10 sin(ω(t − c))
10 = 10 sin(ω(14 − c))
1 = sin(ω(14 − c))
ω(14 − c) = π/2 -1)
At 2:00 A.M. that is t= 2 hours the pressure is 80 mmHg
80 = 90 + 10 sin(ω(t − c))
-10 = 10 sin(ω(2 − c))
3π/2 = ω(2 − c) -2)
dividing 2) with 1) we get
3 = (14 − c) /(2 − c)
6 - 3c = 14 - c
2c = -8
c = - 4
Substituting the value of c in 1) we get,
ω(14 − (-4)) = π/2
ω18 = π/2
ω = π/36
Thus the equation becomes P = 90 + 10 sin(π/36(t +4 ))

12. The average bowling score of the 5-member in Regional High School bowling team is 128. If all the members of the team get the same score except for one, who bowls a 160, what is the score of the rest of the players? (A) 32 (B) 96 (C) 120 (D) 144
Answer:
C
Step-by-step explanation:
The average is the total of the scores divided by 5.
128 x 5 Gives us the total scores of 640. I know that one bowler had a score of 160. I will subtract that from the total of 640. 640-160 = 480. Since the 4 bowlers left, all had the same score, I will divide 480 by 4 to get 120

the accompanying diagram shows a kit that has been secured to skate in the ground with a 20-foot string. the kit is located 12 feet from the ground, directly over point X. what is the distance, in feet, between the skate and point X.
The distance between the skate and point X is 16 feet
Given that the distance between point X and kite is 12 feet
and the distance between stake and kite is 20 feet
We need to find the distance between the stake and point X
Here,
Perpendicular = 12 feet
Hypotenuse = 20 feet
Base = ?
According to Pythagoras Theorem
(Hypotenuse)² = (Perpendicular)²+(Base)²
(20)² = (12)² + (Base)²
∴ (Base)² = 400 - 144
∴ (Base)² = 256
∴ Base = 16 feet

If 5/6 is 180, what is 1/6?
(please explain as well)
Answer: 36
Step-by-step explanation:
If 5/6 = 180
lets find what 1/6 equals
To do this lets divide 180 by 5 to find 1/6
[tex]\frac{180}{5} =36[/tex]
Therefore, 1/6 = 36
We know 180/5 will give us the answer because 180 is already 5/6 of the total; dividing by 5 will give us 1/6 of the total. Ex: if we had 4/6 of the total, we would divide by 4 to find 1/6.
Anyways, we can check our answer by doing:
36*5 = 216 then taking 5/6 of 216, which should equal 180
[tex]216*\frac{5}{6} =180[/tex]
Therefore, we know 36 is the correct answer
A prism with a heart-shaped base is sliced parallel to the base. What shape is formed?
The shape formed, when a prism with a heart-shaped base is sliced parallel to the base, will be congruent to its base. Hence, it will also be heart-shaped.
A prism is a polyhedron made up of n parallelogram faces that connect the n-sided polygon base, the second base, which is a translated duplicate of the first base, and the n faces. The bases are translated into all cross-sections that are parallel to them.
In the question, we are informed that a prism with a heart-shaped base is sliced parallel to the base.
We are asked what shape is formed.
From the above discussion, we know that the bases are translated into all cross-sections that are parallel to them, that is, all cross-sections parallel to the base, will be congruent to the base.
