Given point P moving along a curve y = x²-1 and point Q moving along a line y = x-3. Find the coordinate of point Q and distance between P and Q that makes the distance between two points have minimum value. Show your work, thank you!
Answer:
Part A
The coordinates of point Q that makes the distance between the two points have minimum value is (9/8, -15/8)
Part B
The distance between P and Q at the closest point is approximately 1.287 units
Step-by-step explanation:
From the details given in the question, we have;
The curve along which point P is moving is, y = x² - 1
The (straight) line along which point Q is moving is, y = x - 3
The domain of the path of point P = All real numbers
The range of the path of point P = -1 < x ≤ ∞
The domain of the path of point Q = All real numbers
The range of the path of point Q = All real numbers
From the graph of the functions created with Microsoft Excel, we have that from point (0, 0) and moving to the positive x-axis, the slope of the path of P increases from 0 to ∞, while the slope of the path Q is constant and equal to 1
Given that the path of P is convex relative to the path of P, the two paths will be closest when they have equal slopes
Therefore at the closest point, for the path of point P, we have;
d(x² - 1)/dx = 1 (the slope of the path of point Q)
2·x = 1
∴ x = 1/2 on the path of point P at the closest point the path of point P to the path of point Q
∴ y = x² - 1 = (1/2)² - 1 = -3/4
y = -3/4
Given that two paths are parallel at the closest point, distance between the two paths is the perpendicular distance from the line y = x - 3 to the point (1/2, (-3/4)), which is given as follows;
∴ The slope of the line representing the perpendicular distance between the two paths = -1
Therefore, the equation of the line in point and slope form is given as follows;
y - (-3/4) = -1 × (x - 1/2)
y = -x + 1/2 - 3/4 = -x - 1/4
y = -x - 1/4
At the coordinates of point Q that makes the distance between the two points have minimum value, we have;
-x - 1/4 = x - 3
∴ 2·x = 3 - 3/4 = 2 1/4 = 9/4
x = 9/8
y = x - 3 = 9/8 - 3 = -15/8
Therefore, the coordinates of point Q that makes the distance between the two points have minimum value = (9/8, -15/8)
Part B
The formula for the length between two points is
[tex]l =\sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
The distance, d, between P and Q at the closest point is given as follows;
d = √(((9/8) - (1/2))² + ((-15/8) - (-3/4))²) = √(53/32) ≈ 1.287
The distance between P and Q at the closest point, d ≈ 1.287

On Thursday it snowed 3 ½ inches in 4 hours. On Friday it snowed 8 inches in 9 hours. On which day was it snowing faster?
Answer:
Friday
Step-by-step explanation:
Thursday 7/2 ÷ 4 = 7/8 inches an hour (.875)
Friday 8 ÷ 9 = 8/9 inches an hour (.888)
Friday it was snowing faster
Answer:
Friday
if Thursday snowed 3½ inch 4 hours
then for Friday
9 ÷ 8 = 1.125 inches for one hour
1.125 × 4 = 4.5 inches for 4 hours
1.25 inches more than Thursday. So, the answer is Friday ^^

John tossed a coin 50 times, and it lands on head 27 times and it lands on tails 23 times. What is the relative frequency of landing on heads?
A. 27%
B. 46%
C. 50%
D. 54%
Answer:
D. 54%
Step-by-step explanation:
Find the relative frequency of it landing on heads by dividing 27 by 50, then multiplying it by 100
27/50
= 0.54
0.54(100)
= 54
So, the relative frequency is 54%
The correct answer is D. 54%

Find the perimeter RST. Round answer to the nearest tenth. Show all the work !!!
Given:
The figure of a triangle RST on a coordinate plane.
To find:
The perimeter of the triangle RST.
Solution:
From the given graph it is clear that the vertices of the given triangle are R(-2,7), S(-5,1) and T(-7,-5).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get
[tex]RS=\sqrt{\left(-5-\left(-2\right)\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-5+2\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-3\right)^2+\left(-6\right)^2}[/tex]
on further simplification, we get
[tex]RS=\sqrt{9+36}[/tex]
[tex]RS=\sqrt{45}[/tex]
[tex]RS=3\sqrt{5}[/tex]
Similarly,
[tex]ST=\sqrt{\left(-7-\left(-5\right)\right)^2+\left(-5-1\right)^2}[/tex]
[tex]ST=2\sqrt{10}[/tex]
[tex]RT=\sqrt{\left(-7-\left(-2\right)\right)^2+\left(-5-7\right)^2}[/tex]
[tex]RT=13[/tex]
Now, the perimeter of the triangle RST is
[tex]Perimeter=RS+ST+RT[/tex]
[tex]Perimeter=3\sqrt{5}+2\sqrt{10}+13[/tex]
[tex]Perimeter=26.032759[/tex]
[tex]Perimeter\approx 26.0[/tex]
Therefore, the perimeter of the triangle RST is 26.0 units.

Which inequality does the graph represent?
1. x>17
2.x<17
3.x<_17
4.x>_17
Answer:
1. x > 17
Step-by-step explanation:
When the point on the graph is an open circle you are going to be using < or > as an open circle means greater than or less than
Immediately we can eliminate number 3 and 4
When the line is going in the direction of the right than the inequality sign will face the variable (x)
the numbers are getting larger meaning that x is greater than the constant (17)
Hence, your answer is x > 17
Extra notes:
when the point on the graph is a closed circle ( filled in ) then you will use ≤ or ≥ as a closed circle means greater than or equal to or less than or equal to
Answer:
1. x > 17

Ayden had a goal of finishing painting at least 80\%80%80, percent of the 500500500 square meters of a house's walls by today. He actually finished painting 415415415 square meters today. Did Ayden meet his goal? Why? , Ayden painted square meters than his goal.
Answer: Yes, [tex]15\ m^2[/tex]
Step-by-step explanation:
Given
The surface area of the house [tex]A=500\ m^2[/tex]
Ayden aims to finish 80% of the painting
The actual painting done by him is [tex]A_c=415\ m^2[/tex]
Now 80% of the total is
[tex]\Rightarrow A'=500\times \dfrac{80}{100}=400\ m^2[/tex]
Clearly, actual painting done is more than 80% of the painting
[tex]\therefore[/tex] Ayden meet his goal
[tex]\Rightarrow A_c-A'=415-400=15\ m^2[/tex]
He painted [tex]15\ m^2[/tex] more than his target

Solve the equation and check.
37x + 16 = 6(6x + 6)
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The solution is
(Simplify your answer.)
B. The solution is all real numbers.
OC. There is no solution.
Answer:
x = 20.
Step-by-step explanation:
37x + 16 = 6(6x + 6)
Distribute.
37x + 16 = 36x + 36
Subtract 36x from both sides.
x + 16 = 36
Subtract 16 from both sides.
x = 20.
The solution is 20.
Proof
37x + 16 = 6(6x + 6)
37(20) + 16 = 6(6(20) + 6)
740 + 16 = 6(120 + 6)
756 = 6(126)
756 = 756.
Find the missing height of the solid figure
9514 1404 393
Answer:
5 in
Step-by-step explanation:
The figure's angles are presumed to be right angles everywhere, so the left-side vertical dimension is equal to the right-side vertical dimension.
The right side is marked as 15 inches.
The left side has two vertical segments, one of which is 10 inches. Since the total left-side height must be the same as the right-side height, we have ...
10 in + ? = 15 in
? = 5 in . . . . . . subtract 10 in
The missing height is 5 inches.

given the following sequences : -17 -25 -33 -41... write an explicit formula and find the 28th term in this sequence
Answer:
a(n) = -8n -9
a(28) = -233
Step-by-step explanation:
a(n) = a(1) + (n - 1)d
n is the nth term, a(1) is the first term, d is the common difference.
*d = -25 - (-17) = -8
a(n) = -17 + (n - 1)(-8)
= -17 + (-8n + 8)
= -17 - 8n + 8
= -8n - 9
For the 28th term
a(28) = -8(28) - 9
= -224 - 9
= -233

Answer: D, -13<-10
Step-by-step explanation:
Which ever way the open part of the '<' is facing, means that it is greater than the other number.
-13 is smaller than -10 so the open part of the symbol would face towards -10 and the pointy part would fact towards the -13.
Hope this helps :)
