2. On rectangle ABCD below, if A is located at
(3, 4) and B is located at (7,6), is the slope
of BC ?
Answer: The slope of BC is -2.
Step-by-step explanation:
We know that a rectangle has all opposite sides equal and parallel.
Each interior angle is a right angle.
Therefore , if rectangle ABCD is a rectangle then , AB should perpendicular to BC. [ ∵ Angle between AB and BC is 90° .] (1)
Also , slope of line passing through (a,b) and (c,d) : [tex]\dfrac{d-b}{c-a}[/tex]
If A is located at (3, 4) and B is located at (7,6) .
Then , The slope of AB = [tex]\dfrac{6-4}{7-3}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]
Also, the product of slopes of two perpendicular lines is -1.
Then , (Slope of AB) x (Slope of BC) = -1 [From (1)]
[tex]\Rightarrow\ \dfrac{1}{2}\times (\text{Slope of BC})= -1\\\\\Rightarrow\ \text{Slope of BC}=-2[/tex]
Hence, the slope of BC is -2.

Isolate the identity
cos 2x - cos 8x
cos 2x + cos 8x
HELP PLS
Answer:
Cos 2x = Cos (5x-3x)
Cos(5x)Cos(3x) + Sin(5x)Sin(3x)
Cos 8x = Cos (5x + 3x)
Cos(5x)Cos(3x) - Sin(5x)Sin(3x)
Cos 2x - Cos 8x
= Cos(5x)Cos(3x) + Sin(5x)Sin(3x) -
[Cos(5x)Cos(3x) - Sin(5x)Sin(3x)]
= 2Sin(5x)Sin(3x)
Cos 2x + Cos 8x
= Cos(5x)Cos(3x) + Sin(5x)Sin(3x) +
[Cos(5x)Cos(3x) - Sin(5x)Sin(3x)]
= 2Cos(5x)Cos(3x)
= 2Sin(5x)Sin(3x) ÷ 2Cos(5x)Cos(3x)
2 gets cancelled out
Sin(5x)/Cos(5x) is Tan(5x)
Sin(3x)/Cos(3x) is Tan(3x)
Hence the fraction is identical to
Tan(5x)Tan(3x)
Ryan measures a rectangle that is 9 feet long and 5 feet wide. Teo measures a rectangle that has an area of 36 square feet. Which rectangle has the greater area/ explain
Answer:
Teo's rectangle has the greater area.
Step-by-step explanation:
Since a rectangle has the same opposite sides of parallel sides, you need to add or multiply 9 times 9 or 9 + 9 and 5 times 5 or 5 + 5. 9 x 9 or 9 + 9 equals 18, and 5 + 5 or 5 x 5 equals 10. Then, 18 and 10 is to be added. 18 + 10 is 28. So, that means Teo's rectangle has the greater area because, 28 is less than 36.
To compare the areas of the rectangles, calculate the area of each rectangle. Ryan's rectangle has a greater area of 45 square feet compared to Teo's rectangle which has an area of 36 square feet.
Explanation:To compare the areas of the two rectangles, we need to calculate the area of each rectangle. The area of a rectangle is found by multiplying its length by its width. For Ryan's rectangle, the length is 9 feet and the width is 5 feet, so the area is 9 feet × 5 feet = 45 square feet. For Teo's rectangle, we are given that the area is 36 square feet. Since 45 is greater than 36, Ryan's rectangle has the greater area.

In the diagram, HK is tangent to Circle O. If HK is 24mm and the length from H to the
edge of the circle along OH is 18mm, what is the length of the radius of the circle?
Answer:
The length of the radius of the circle is 7 mm
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If HK is tangent to circle O at point K
then
The radius OK is perpendicular to segment HK and triangle OKH is a right triangle
Applying the Pythagorean Theorem
[tex]OH^2=OK^2+HK^2[/tex]
we have
[tex]OH=(r+18)\ mm\\OK=r\ mm\\HK=24\ mm[/tex]
substitute
[tex](r+18)^2=r^2+24^2[/tex]
solve for r
[tex]r^2+36r+324=r^2+576[/tex]
[tex]36r=576-324\\36r=252\\r=7\ mm[/tex]

when the number is not a perfect square?
The product of a rational number multiplied by itself is called as a perfect square.,we can easily find out the square root for a number which is a imperfect square
Step-by-step explanation:
using the following formula we can find a square root for a number which is a imperfect square
X = Non perfect square
√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )
[tex]√x = (square root of nearest lower perfect square +(x - perfect square)÷2×(√perfect square )[/tex]Example
√38
the nearest perfect root is 36
36 (√36=6)
so √38 = √36 + (38-36)/2√36
= 6 + 2/12
=6 + 1/6 = 6.166 (answer)
[tex]√38 the nearest perfect root is 36 36 (√36=6)so √38 = √36 + (38-36)/2√36 = 6 + 2/12=6 + 1/6 = 6.166 (answer)[/tex]
To find the square root of a non-perfect square, use estimation techniques or the quadratic formula if in relation to an equation. Use the imaginary unit i for square roots of negative numbers, and simplify by removing perfect squares when adding or subtracting radicals.
Finding the square root of a number that is not a perfect square can be done using a few different methods. One simple non-calculator method is to use estimation and refinement; start with an approximate guess and improve it. When dealing with negative numbers, remember that we use the imaginary unit i to denote the square roots of negative numbers. For example, a₂ can be written as 2i. Adding and subtracting radicals involves simplifying each radical by removing perfect squares and combining like terms.
For equations where the square root is part of a quadratic equation, ax²+bx+c = 0, if a, b, and c are non-zero, we should use the quadratic formula to find solutions. Estimation also applies when dealing with cube roots or higher, where we can start with an initial guess and use methods like calculus to refine it.
To estimate a surd like a₃ without a calculator, consider its place on the number line between two integers, knowing that a₃ is about 1.732. This helps get an approximate value which is often sufficient for many applications.

Answer:
Kyle must rent the jetski for three hours for option 2 to be a better deal than option 1
Solution:
Let "x" be the number of hours
Option 1: $30 an hour plus a non-refundable deposit of $50.Therefore,
Charge for option 1: 50 + 30x
For 1 hour,
Charge = 50 + 30(1) = 80
For 2 hours,
Charge = 30(2) + 50 = 110
For 3 hours,
Charge = 30(3) + 50 = 140
For 4 hours,
Charge = 30(4) + 50 = 160
Option 2: $20 an hour plus a non-refundable deposit of $75Charge for option 2 : 75 + 20x
For 1 hour,
Charge = 20(1) + 75 = 95
For 2 hours ,
Charge = 20(2) + 75 = 115
For 3 hours,
Charge = 20(3) + 75 = 135

The difference of a number and six is seven. Find the number.
Answer 13-6=7
Step-by-step explanation:
The given expression indicates a difference of six and an unknown number equals to seven. To solve, we isolate the unknown number by adding six to both sides of the equation. Thus, the unknown number is 13.
Explanation:The question states that 'The difference of a number and six is seven.' To find out the number, we can set up the following equation where x represents our unknown number:
x - 6 = 7
To solve for x, we can add 6 to both sides of the equation, which balances it rendering the final result:
x = 7 + 6

How long is the minor axis for the ellipse shown below?
(x+3)^2/64 + (y-7)^2/4=1
A. 16
B. 4
C. 8
D. 64
Imagine is shown above.
The length of the minor axis is 4
Step-by-step explanation:
Step 1 :
The given equation is [tex]\frac{(x-3)^{2}}{64} + \frac{(y-7)^{2}}{4} = 1[/tex]
Here we see the denominator below the variable x is greater than below y. Hence the ellipse's major axis and the minor axis are parallel to x-axis and y-axis respectively
Step 2 :
The square of the semi minor axis will be the denominator of the y variable. So in the given ellipse ,
the square of the semi minor axis = 4
Hence the length of the semi minor axis = [tex]\sqrt{4}[/tex] = 2
Step 3 :
The length of the minor axis = 2 times the length of the semi minor axis
= 2 × 2 = 4
Answer :
The length of the minor axis is 4
Final answer:
The length of the minor axis of the given ellipse is 4 units, as the semi-minor axis length is derived from the square root of the denominator of the y-term in the ellipse equation. The correct option is B.
Explanation:
The minor axis of an ellipse is the shortest diameter of the ellipse, and it runs perpendicular to the major axis. In the given equation of the ellipse, (x+3)²/64 + (y-7)²/4=1, the denominators of the fractions correspond to the squares of the semi-axes lengths. Therefore, the length of the semi-minor axis 'b' is the square root of 4, which is 2. Since the minor axis is twice the length of the semi-minor axis, we must multiply 2 by 2 to get the length of the minor axis, which is 4.
So the correct answer for the length of the minor axis for the given ellipse is 4 units, which corresponds to option B.
