Can anyone help me ??
Answer:
1/2
Step-by-step explanation:
Point A is (2, 3)
Point B is (6, 5)
To get the slope of a line, first select any two points on that line.
Then, take the difference of the y values, and divide it by the difference of the x values. This is also known as the change in y over the change in x, or rise over run.
[tex]\frac{3-5}{2-6} =\frac{-2}{-4} =\frac{1}{2}[/tex]
1/2 is the slope.

A $40 shirt now selling for $28 is discounted by what percent?
Answer:
30%
Step-by-step explanation:
Think of this as converting a fraction. 28/40 to x/100. You do this because in the situation, 40 is 100 percent of the price. So 28 is x percent of 100.
You multiply 40 by 2.5 to get to 100, so multiply 28 by the same number to get x. 28 * 2.5 = 70.
So 28 is 70 percent of 40. But the question is asking by what percentage it is discounted. If it's now selling for 70%, it has been discounted 30%. So the answer is 30%

SAT scores are normally distributed with a mean of
500 and a standard deviation of 60. Find the z-score
of an SAT score of 380.
Answer:
the z-score for the sat score of 380 is 2
Step-by-step explanation:
the way i got this is you got to take the standard deviation value and subtract it from the mean since the value 380 is less than 500.
500-60=440-60=380
so the answer would be a z-score of 2

step and justification of root√3.5
[tex] \large \boxed{ \boxed{ \sqrt{3.5} }}[/tex]
In this case, we are going to use the 'Babylonian method to get the square root of any positive number.We must define an error for the final result.Say, less than 0.01. In other words, we will try to find the value of the square root to at least 1 correct decimal places.
Step 1:
Divide the number (3.5) by 2 to get the first guess for the square root. first guess = 3.5 / 2 = 1.75.Step 2:
Divide 3.5 by the result obtained in stepprevious. d = 3.5 / 1.75 = 2.Roll the arithmetic mean of (d) and the obtained valuein step 1: (2 +1.75) / 2 = 1.875 (newapproach).
Error = new guess - previous value = 1.75 1.875 = 0.125.0.125 0.01. As the error> accuracy, please repeat thist happened one more time.Step 3:
Divide 3.5 by the result obtained in the previous step. d = 3.5 / 1.875 = 1.8666666667.Roll the arithmetic mean of (d) and the value obtained in step 2: (1.8666666667 + 1.875) / 2 =1.8708333334 (new approximation).Error = new guess - previous value = 1.875 -1.8708333334 = 0.00416666660.0041666666 <0.01. Once the error <accuracy, stop the process and use 1.8708333334 as the final value for the square root.Then we can say that the square root of 3.5 is 1.87 with an error less than 0.01 (actually the error is 0.0041666666). This means that the first 2 decimal places are correct. Just for comparison, the returned value using the javascript function Math.sqrt (3.5) 'is 1.8708286933869707.Note: There are other ways to calculate square root. This is just one of them.

Michelle invested $10,000 in an account that earns 8.5% interest that is compounded monthly. Determine the amount of money in the account in 15 years
Given:
The principal value = $10,000
Rate of interest = 8.5% compounded monthly.
To find:
The amount of money in the account in 15 years.
Solution:
The formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded in an year, t is the number of years.
Number of months in an year is 12. So, n=12.
Substitute [tex]P=10000, r=0.085, n=12, t=15[/tex] in the above formula.
[tex]A=10000\left(1+\dfrac{0.085}{12}\right)^{12(15)}[/tex]
[tex]A=10000\left(\dfrac{12.085}{12}\right)^{180}[/tex]
[tex]A=35626.53335[/tex]
[tex]A\approx 35626.53[/tex]
Therefore, the amount of money in the account in 15 years is $35626.53.
I need help on this angles on a straight line problem, it involves algebra. I don't need an explanation just the answer please.
Answer:
m<COD = 46°
Step-by-step explanation:
All the angles are supplementary to each other, so we can combine them and set them equal to 180° to solve for x:
(3x+88)°+(x+36)°+(2x-4)°=180°
3x+88+x+36+2x-4=180
6x+120=180
6x=60
x=10
Since we know x=10, then <COD is 10+36 = 46°
Answer:
∠COD = 46°
Step-by-step explanation:
∠AOB (or straight line) = 180°
3x + 88° + x + 36° + 2x - 4° = 180°
combine like terms:
6x + 120° = 180°
subtract 120° from both sides of the equation:
6x = 60°
divide both sides by 6:
x = 10°
∠COD = 10° + 36° = 46°
The line segments connecting the points (x1, y1), (x2, y1), and (x2, y2) form a triangle. Is the triangle a right triangle?
Answer:
Indeed, the given triangle is a right triangle.
Step-by-step explanation:
A triangle is formed by the following three points: [tex]A(x,y) = (x_{1}, y_{1})[/tex], [tex]B(x,y) = (x_{2}, y_{1})[/tex] and [tex]C(x,y) = (x_{2}, y_{2})[/tex]. Then, we construct the following vectors:
[tex]\overrightarrow {BA} = (x_{2}-x_{1}, y_{1}-y_{1})[/tex]
[tex]\overrightarrow{BA} = (x_{2}-x_{1}, 0)[/tex] (1)
[tex]\overrightarrow{BC} = (x_{2}-x_{2}, y_{2} - y_{1})[/tex]
[tex]\overrightarrow{BC} = (0, y_{2}-y_{1})[/tex] (2)
If triangle ABC is a right triangle, then [tex]\overrightarrow{BA}\,\bullet\,\overrightarrow{BC} = 0[/tex]. By (1) and (2) we have this expression:
[tex](x_{2} - x_{1})\cdot (0) + (0)\cdot (y_{2} - y_{1}) = 0[/tex]
Therefore, the given triangle is a right triangle.

<1 and <2 form a linear pair. The measure of <1 = (2x+8) and the measure of <2 = (8x + 22). What is the measure of <1?
Answer:
Step-by-step explanation: Since the given problem states that the two angles, angle 1 and angle 2 form a linear pair, this means that they form a 180° line, so that:
measure angle 1 + measure angle 2 = 180°
Since measure of angle 2 is six more than twice the measure of angle 1, therefore:
measure angle 2 = 2 (measure angle 1) + 6
hence, substituting this into the first equation:
measure angle 1 + 2 (measure angle 1) + 6 = 180
3 (measure angle 1) = 174
measure angle 1 = 58°
Therefore,
measure angle 2 = 2 (measure angle 1) + 6
measure angle 2 = 2 (58°) + 6
measure angle 2 = 122*

Which type of transformation (reflection, rotation or translation) is most difficult for you to perform? Which is the easiest? Why do you think this is?
Answer:
Easiest: Translation
Most difficult: rotation
Step-by-step explanation:
- Translation involves just moving of an image without any changes anything about it from size to orientation to shape. Therefore, the translated image is exactly the same as the original one just that it is moved to a different place.
- Rotation involves rotating the image by a certain angle.
For example, we can rotate an image by 30°, 45°, 60° e.t.c.
- Reflection is simply the mirror image of an existing image which is basically flipping the original image along a vertical or horizontal line which acts like a mirror.
Looking at these definitions, the easiest will be translation because we are not changing any single thing but just moving from one place to another while the most difficult would be rotation because it involves rotating at an angle which one may not easily get correctly.
What is the amplitude of the graph of y = 2sin(4x - 1) + 3 ?
Answer: 2
Step-by-step explanation:
The amplitude of the function of graph y = 2sin(4x - 1) + 3 is 2.
What is the graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is function?The function is defined as mathematics expression defines a relationship between one variable and another variable.
What is the amplitude of function?A amplitude of function is defined as periodic variable's amplitude is a measure of its change over a single period. A non-periodic signal's magnitude in relation to a standard value is its amplitude.
Given the function of graph as :
y = 2sin(4x - 1) + 3
Comparing the form asin(bx - c) + d to determine the amplitude, period, phase shift, and vertical shift.
