square root of, 29, end square root.
Where does the point T(5,-2)T(5,−2)T, left parenthesis, 5, comma, minus, 2, right parenthesis lie?
Answer:
Point T is on the circle
Step-by-step explanation:
To check where the point lies, we need to find its distance to the center of the circle.
The distance between two points (x1, y1) and (x2, y2) is given by:
[tex]distance = \sqrt[2]{(x2 - x1)^{2} + (y2 - y1)^{2}}[/tex]
If the first point is O(0,0) and the second is T(5, -2), we have:
[tex]distance = \sqrt[2]{(5 - 0)^{2} + (-2 - 0)^{2}}[/tex]
[tex]distance = \sqrt{29}[/tex]
The distance between the points is equal the radius of the circle, that means the point T is on the circle.

Noah says that 9x - 2x + 4x is equivalent to 3x, because the subtraction sign tells us to subtract everything that comes from after 9x. Elena says that 9x - 2x + 4x is equivalent to 11x, because the subtraction only applies to 2x. Do you agree with either of them? Explain ur reasoning. i
Agree with Elena, because 9x - 2x + 4x is equivalent to 11x, after the subtraction only applies to 2x.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Noah says that 9x - 2x + 4x is equivalent to 3x, because the subtraction sign tells us to subtract everything that comes from after 9x.
And, Elena says that 9x - 2x + 4x is equivalent to 11x, because the subtraction only applies to 2x.
Now,
Since, We know that;
⇒ 9x - 2x + 4x
⇒ 7x + 4x
⇒ 11x
Thus, Elena is correct as;
⇒ Elena says that 9x - 2x + 4x is equivalent to 11x, because the subtraction only applies to 2x.

Calculate the interquartike range (IQR=Q3-Q1) of the following data 17, 18, 18, 19, 20, 21, 21, 23, 25
Answer:
4
Step-by-step explanation:
20 is the median
so before and after 20 is the Q3 and Q1
Q1 is 18
Q3 is 22
22 minus 18
The Interquartile range, IQR of the numbers is 4
The process of calculating the above Interquartile Range, IQR is as follows;
The given numbers in the data set are;
17, 18, 18, 19, 20, 21, 21, 23, 25
The required information;
Calculate the inter quartile range IQR = Q₃ - Q₁
The method;
The numbers in the data set are to be arranged in increasing order from smallest to largest number to give;
17, 18, 18, 19, 20, 21, 21, 23, 25 (The numbers were already arranged)
The values of first quartile, Q₁, and the third quartile, Q₃ are then found as follows;
The first quartile, Q₁ = The (n + 1)/4 th term
The third quartile, Q₃ = The 3·(n + 1)/4 th term
Where;
n = The number count in the data set = 9
Therefore:
Q₁ = The (9 + 1)/4 = The 2.5 th term = 18 + (18 - 18) × 0.5 = 18
Q₃ = The 3 × (9 + 1)/4 th term = 7.5 th term = 21 + (23 - 21) × 0.5 = 22
IQR = Q₃ - Q₁
Therefore;
IQR = 22 - 18 = 4
The Interquartile Range, IQR = 4

in the following triangle theta=60.Find the values of the angles of the angles B and B'
lengths of sides are 15.4 on the first two and 16 on the third side
Answer:
∠B` = 109.73°, ∠B = 70.27°
Step-by-step explanation:
∠B + ∠B` = 180°
The Sine Law:
10 / sin B` = 9.2 / sin 60°
10 / sin B` = 9.2 / √3/2
sin B` = 0.94133
B` = sin^(-1) 0.94133
∠B` = 109.73°, ∠B = 70.27°
On a coordinate plane, a circle has a center at (0, 0). Point (3, 0) lies on the circle.
Distance formula: StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot
Does the point (2, StartRoot 6 EndRoot) lie on the circle shown? Explain.
Yes, the distance from (3, 0) to (0, 0) is 3 units.
Yes, the distance from (0, 0) to (2, StartRoot 6 EndRoot) is 3 units.
No, the distance from (3, 0) to (2, StartRoot 6 EndRoot) is not 3 units.
No, the distance from (0, 0) to (2, StartRoot 6 EndRoot) is not 3 units.
Answer:
The correct option is;
No, the distance from (0, 0) to (2, √6) is not 3 units
Step-by-step explanation:
The given parameters of the question are as follows;
Circle center (h, k) = (0, 0)
Point on the circle (x, y) = (3, 0)
We are required to verify whether point (2, √6) lie on the circle
We note that the radius of the circle is given by the equation of the circle as follows;
[tex]Distance \, formula = \sqrt{\left (x_{2}-x_{1} \right )^{2} + \left (y_{2}-y_{1} \right )^{2}}[/tex]
Distance² = (x - h)² + (y - k)² = r² which gives;
(3 - 0)² + (0 - 0)² = 3²
Hence r² = 3² and r = 3 units
We check the distance of the point (2, √6) from the center of the circle (0, 0) as follows;
[tex]\sqrt{\left (x_{2}-x_{1} \right )^{2} + \left (y_{2}-y_{1} \right )^{2}} = Distance[/tex]
Therefore;
(2 - 0)² + (√6 - 0)² = 2² + √6² = 4 + 6 = 10 = √10²
[tex]\sqrt{\left (2-0 \right )^{2} + \left (\sqrt{6} -0 \right )^{2}} = 10[/tex]
Which gives the distance of the point (2, √6) from the center of the circle (0, 0) = √10
Hence the distance from the circle center (0, 0) to (2, √6) is not √10 which s more than 3 units hence the point (2, √6), does not lie on the circle.

Elmer purchased a used vehicle that depreciates under a straight line method. The initial value of the car is $9600 and the salvage value is $600. If the car is expected to have a useful life of another 6 years, how much will it depreciate each year?
A. $100.00
B. $1500.00
C. $3600.00
D. $600.00
Answer:
The depreciation each year is option B. $1500.00
Step-by-step explanation:
Initial value of car = $9600
Salvage value = $600
Salvage value is the final value of product after all the depreciation have been applied on the product.
So, total depreciation on the car = [tex]\$9600 - \$600 \Rightarrow \$9000[/tex]
Also, it is given that the depreciation occurs at a straight line method i.e. same depreciation occurs every year.
Depreciation in 6 years = $9000
Depreciation in 1 year =
[tex]\dfrac{\$9000}{6} \Rightarrow \$1500[/tex]
Hence, option B. $1500 is the correct answer for the depreciation every year.

The value of x in the model that makes the equation true is: b. x = 2.25
We can find the value of x that makes the equation true by applying our knowledge of how to model equations.
From the image given:
On your left, we have -x, in three places which can be translated to as: [tex]3 \times -x = -3x[/tex]On the left also, we are given [tex]10 \times 1 = 10[/tex]We can model the left side as:[tex]-3x + 10[/tex]
On your right, we have x in five places which can be translated to as: [tex]5 \times x = 5x[/tex]On the right also, we are given [tex]8 \times -1 = -8[/tex]We can model the left side as:[tex]5x - 8[/tex]
The equation would be:[tex]-3x + 10 = 5x - 8[/tex]
Solve the equation for the value of x. Collect like terms.[tex]-3x - 5x = - 8 - 10\\\\-8x = -18[/tex]
Divide both sides by -8[tex]x = \frac{-18}{-8} \\\\x = 2.25[/tex]

Write the equation of the line with the following characteristics. Parallel to y=7x+2 through the point (0,0)
Answer:
y = 7x - 5
Step-by-step explanation:
y = 7x+2 we see the gradient is 7 (x 0) + 2 = Since the line is parallel to y= 7x +2
The new line has a slope of 7 + 2 as the intercept at y.
y - 0 = 7 ( x - 0)
y - 1/7 = x - 0
y = 7x - 5
As 7 -5 = 2
Hence equation of line becomes y=7x.
What is Equation of line?You must ensure that both equations have the same slope in order to find an equation for a line that is parallel to another. The m reflects your slope value in the general equation of a line, y=mx+b.
How to solve?Now given line y=7x+2 ,this line is parallel to another line which passes through origin(0,0)
Hence putting 0,0 in general equation to find equation of parallel line
⇒y=mx+c
⇒0=m(0)+c
⇒0=c
where m=7 as parallel lines have same slope.

[tex]Sin156[/tex]
Step-by-step explanation:
Given
[tex]Sin24[/tex]
Required
Find equivalent between 0 to 180;
Let 24 be represented by [tex]\theta[/tex]
So, [tex]\theta = 24[/tex]
From Trigonometry ratios;
[tex]Sin\theta = Sin(180 - \theta)[/tex] where [tex]0\leq \theta \leq 180[/tex]
Recall that [tex]\theta = 24[/tex]
So, we have to substitute 24 for [tex]\theta[/tex] in the above expression.
This gives
[tex]Sin24= Sin(180 - 24)[/tex]
Subtract 24 from 180
[tex]Sin24= Sin156[/tex]
Hence, the equivalent of [tex]Sin24[/tex] is [tex]Sin156[/tex]
