We have on the denominator the next expression:
\((x-3)(x+2)(x-5)\)The function is not defined when the denominator is equal to 0.
\((x-3)(x+2)(x-5)\ne\text{ 0}\)So the function is undefined when
x-3 =0
x+2=0 and
x-5 = 0
Solving for x:
x=3
x=-2
x=5.
With the before information, we can find that Bobby is right, the function is undefined when x=3. x=-2 and x=5.
In ΔWXY, w = 170 inches, x = 590 inches and y=630 inches. Find the measure of ∠Y to the nearest 10th of a degree.
Therefore, the measure of angle ∠Y to the nearest tenth of a degree is approximately 103.2 degrees.
To find the measure of angle ∠Y, we need to use the law of cosines, which relates the lengths of the sides of a triangle to the cosine of its angles.
The formula for the law of cosines is:
\(c^2 = a^2 + b^2 - 2ab cos(C)\)
Where a, b, and c are the lengths of the sides of the triangle, and C is the angle opposite to side c.
In our case, we know the lengths of the sides w, x, and y, and we want to find the angle ∠Y, which is opposite to side y. So, we can use the formula as follows:
\(y^2 = w^2 + x^2 - 2wx cos(Y)\)
Substituting the values, we have:
\(630^2 = 170^2 + 590^2 - 2(170)(590) cos(Y)\)
Simplifying and solving for cos(Y):
\(cos(Y) = (170^2 + 590^2 - 630^2) / (2170590)\)
cos(Y) ≈ -0.236
Note that the cosine of an angle is negative if the angle is between 90 and 180 degrees, which is the case for angle ∠Y in this triangle. Therefore, we need to use the inverse cosine function to find the measure of angle ∠Y:
Y ≈ 103.2 degrees
Rounding to the nearest tenth of a degree, we get:
Y ≈ 103.2°
Therefore, the measure of angle ∠Y to the nearest tenth of a degree is approximately 103.2 degrees.

tan(x-1) ( sin2x-2cos2x) = 2(1-2sinxcosx)
\(\huge\blue{\fbox{\tt{Solution:}}}\)
We can simplify the expression using trigonometric identities.
First, we can use the double angle formula for sine to write sin(2x) = 2sin(x)cos(x).
Next, we can use the double angle formula for cosine to write cos(2x) = cos^2(x) - sin^2(x) = 1 - 2sin^2(x). Rearranging this equation gives 2sin^2(x) - 2cos^2(x) = -cos(2x) + 1.
Substituting these identities into the original expression gives:
tan(x-1) ( sin2x-2cos2x) = tan(x-1) [2sin(x)cos(x) - 2(1 - 2sin^2(x))]
= 2tan(x-1)sin(x)cos(x) - 2tan(x-1) + 4tan(x-1)sin^2(x)
We can use the identity tan(x) = sin(x)/cos(x) to simplify this expression further:
2tan(x-1)sin(x)cos(x) - 2tan(x-1) + 4tan(x-1)sin^2(x)
= 2sin(x)cos(x)/(cos(x-1)) - 2sin(x)/(cos(x-1)) + 4sin^2(x)/(cos(x-1))
Multiplying both sides of the equation by cos(x-1) gives:
2sin(x)cos(x) - 2sin(x) + 4sin^2(x)cos(x-1) = 2(1-2sin(x)cos(x))
Expanding the left-hand side of the equation gives:
2sin(x)cos(x) - 2sin(x) + 4sin^2(x)cos(x) - 4sin^2(x) = 2 - 4sin(x)cos(x)
Simplifying this equation gives:
4sin^2(x) - 2sin(x) - 2 = 0
This is a quadratic equation in sin(x), which can be solved using the quadratic formula.

What is an equation of the line that passes through the points (1,6) and (2, 7)?
The equation of the line that passes through the points (1,6) and (2,7) is y = x + 5.
We can use the point-slope version of the equation, which is: to determine the equation of a line passing through two specified points.
y - y₁ = m(x - x₁)
where (x₁, y₁) are the coordinates of one of the points, m is the slope of the line, and (x, y) are the coordinates of any other point on the line.
Use the points (1,6) and (2,7) to find the equation of the line:
Using (x₁, y₁) = (1,6):
y - 6 = m(x - 1)
Now, substitute the coordinates (2,7) into the equation:
7 - 6 = m(2 - 1)
1 = m
So, the slope of the line is m = 1.
Substitute this value into the equation:
y - 6 = 1(x - 1)
y - 6 = x - 1
y = x + 5
Therefore, the equation of the line that passes through the points (1,6) and (2,7) is y = x + 5.

I'm not sure why m is chosen as the slope, but you can think of the phrase "mountains have a slope" to help remember m is involved.
The b is the y intercept.
For example, y = 2x+5 has a slope of 2 and y intercept of 5.
Earthquake A had a magnitude of 8.2 on the Richter scale. At the same time an earthquake B with magnitude 4.6 caused only minor damage. How many times more intense was earthquake A than earthquake B? (Round your answer to two decimal places.)
The Richter scale is logarithmic, which means that for every one-unit increase in magnitude, the energy released by the earthquake increases by a factor of 10.
To calculate how many times more intense earthquake A was than earthquake B, we need to find the difference in their magnitudes and then raise 10 to that power.
The difference in magnitudes is:
8.2 - 4.6 = 3.6
To find how many times more intense earthquake A was than earthquake B, we need to raise 10 to the power of 3.6:
10^3.6 = 3981.07
Therefore, earthquake A was approximately 3981.07 times more intense than earthquake B. Rounded to two decimal places, the answer is 3981.07.

This is grade 10 math. Chapter 2: Analytic Geometry - Line Segments and CirclesDescribe all points that are the same distance from points A(-3,-1) and B(5,3)It’s question 3 from attached screenshot.The answer at the back of text book is y=-2x+3Thank you!
Given:
The given points are A(-3,-1) and B(5,3).
Required:
We need to find the set of all points that are the same distance from the points A(-3,-1) and B(5,3).
Explanation:
Recall that the set of points that are the same distance from the point A(-3,-1) and (5,3) is the perpendicular bisector of the line segment AB.
Consider the slope formula.
\(slope=\frac{y_2-y_1}{x_2-x_1}\)\(Substitute\text{ }y_2=3,y_1=-1,x_2=5,\text{ and }x_1=-3\text{ in the formula to find the slope of AB.}\)\(slope=\frac{3-(-1)}{5-(-3)}=\frac{3+1}{5+3}=\frac{4}{8}=\frac{1}{2}\)We get the slope of the line segment AB is 1/2.
The slope of the perpendicular is the negative reciprocal of the slope of the line segment AB.
\(The\text{ negative reciprocal of }\frac{1}{2}=-2.\)\(The\text{ slope of the perpendicular line is -2.}\)The perpendicular line is passing through the midpoint of A(-3,-1) and B(5,3).
Consider the midpoint formula.
\(midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\)\(Substitute\text{ }y_2=3,y_1=-1,x_2=5,\text{ and }x_1=-3\text{ in the formula to find the midpoint of AB.}\)\(midpoint=(\frac{-3+5}{2},\frac{-1+3}{2})\)\(midpoint=(\frac{2}{2},\frac{2}{2})\)\(midpoint=(1,1)\)Consider the general form of the line equation.
\(y=mx+b\)Substitute m=-2, x=1, and y=1 in the line equation to find b.
\(1=(-2)(1)+b\)\(1=-2+b\)Add 2 to both sides of the equation.
\(1+2=-2+b+2\)\(3=b\)Substitute m=-2 and b=3 in the line equation.
\(y=-2x+3\)We get the perbenticular bisector y =-2x+3.
Final answer:
\(y=-2x+3\)5. Pierre uses a sheet of printer paper for origami. How can he check

a line with y-intercept (0,1) which passes for thought the point (1,1)
Answer:A unique line is defined by any two distinct (not identical) points. You have two distinct, which means you have a line. To find the equation for the line, we start with the slope-intercept equation for a line. This is only a template for a generic line, so we will have to find the specific values of m (slope) and b (y-intercept) that define your line.
The template: y = mx + b
b is the y-intercept, which, if you look at (0,–2), you will see is –2; it is where the line crosses the y-axis. Fill that value of b into our template to get:
y = mx – 2
Now, we only need the value of m, which is the slope. If you have two points on a line, you can calculate the slope of that line. The slope is the change (difference) of y over the change in x (difference) of x for two given points on the line. It's a fraction or ratio though sometimes it can be reduced to an integer.
So, taking your two points, you calculate the slope, m, in the following way:
(x1,y1) = (0,–2)
(x2,y2) = (5,1)
y2 – y1 1 – (–2) 1 + 2 3
m = ________ = ________ = ________ = ____

the number of items sold at store 1 can be represented by y=200x+300 where x represents the number of days and y represents the number of items sold the number of items sold at store 2 can be represented by y=200x+100
There is no day when the Number of cupcakes sold at Location 1 is equal to the number of cupcakes sold at Location 2. on Day 5, Location 2 sold 850 cupcakes.
(a) To determine the number of cupcakes sold at each location on Day 5, we substitute x = 5 into the equations:
For Location 1:
y = 150x + 200
y = 150(5) + 200
y = 750 + 200
y = 950
Therefore, on Day 5, Location 1 sold 950 cupcakes.
For Location 2:
y = 150x + 100
y = 150(5) + 100
y = 750 + 100
y = 850
Therefore, on Day 5, Location 2 sold 850 cupcakes.
(b) To find the day when the number of cupcakes sold at Location 1 is equal to the number of cupcakes sold at Location 2, we set the two equations equal to each other:
150x + 200 = 150x + 100
We can see that the variable x cancels out, which means the value of x doesn't matter in this case. The equation simplifies to:
200 = 100
However, this equation is not true. It implies that the number of cupcakes sold at Location 1 can never be equal to the number of cupcakes sold at Location 2.

Heather invests $4,625 in an account with a 5% interest rate, making no other deposits or withdrawals. What will Heather’s account balance be after 7 years if the interest is compounded 12 times each year?
To calculate the final account balance after 7 years with a 5% interest rate compounded 12 times per year, we can use the formula:
A = P(1 + r/n)^(nt)
where:
A = the final account balance
P = the initial principal (the amount Heather invested), which is $4,625 in this case
r = the annual interest rate, which is 5%
n = the number of times the interest is compounded per year, which is 12 in this case
t = the number of years the money is invested, which is 7 in this case
Substituting these values into the formula, we get:
A = $4,625(1 + 0.05/12)^(12*7)
A = $4,625(1.0041667)^84
A = $4,625(1.480244)
A = $6,849.46
Therefore, Heather’s account balance will be $6,849.46 after 7 years if the interest is compounded 12 times each year.

what is y=-2(x+4)^2-11 in standard form
Answer:
y=2x^2+16x+11
Step-by-step explanation:
Standard form is y=ax^2+bx+c.
In order to write this polynomial in standard form, we need to simplify and then arrange the terms in decreasing order.
Rewrite (x+4)^2 as (x+4)(x+4) and then expand using FOIL.
y=2(x⋅x+x⋅4+4x+4⋅4)−21
Simplify.
y=2(x^2+8x+16)−21
Apply the distributive property and simplify.
y=2x^2+2(8x)+2⋅16−21
y=2x^2+16x+32−21
y=2x^2+16x+11
Therefore,
y=2x^2+16x+11
