Triangle ABC has coordinates A(2, 4), B(5, 6), and C(1, 4). If the triangle is rotated 180° clockwise about the origin, what are the coordinates of B'?
Answer:
B'(-5,-6)
Step-by-step explanation:
The mapping for 180° clockwise rotation about the origin is:
[tex](x,y)\to (-x,-y)[/tex]
The find the image of B(5,6), we plug in x=5 and y=6 into the rule.
[tex](5,6)\to (-5,-6)[/tex]
Therefore the coordinates of B' are (-5,-6).
Point B with coordinates (5, 6) will have coordinates (-5, -6) after a 180° clockwise rotation about the origin.
Triangle ABC has coordinates A(2, 4), B(5, 6), and C(1, 4). If the triangle is rotated 180° clockwise about the origin, we need to find the coordinates of B'.
To rotate a point (x, y) 180° about the origin, we can multiply the coordinates by -1. So, the coordinates of B' after rotation will be (-5, -6).

Express in exponential form. log 3 a = n
Answer:
[tex]\log_3(a)=n[/tex] has exponential form [tex]3^n=a[/tex].
[tex]\log(3a)=n[/tex] has exponential form [tex]10^{n}=3a[/tex].
Please let me know if neither of my interpretations of your problem/question is correct. That is I can either assume you wrote [tex]\log_3(a)=n[/tex] or [tex]\log(3a)=n[/tex].
If something else was intended, please let me know. Thanks kindly.
Step-by-step explanation:
Let's assume: [tex]\log_3(a)=n[/tex].
The base is 3.
The exponent is n. (Just remember the logarithm is the exponent.)
So we have [tex]3^n=a[/tex]
In general these forms are equivalent:
[tex]log_b(a)=y \text{ is equivalent to } b^y=a[/tex].
[tex]\log(3a)=n[/tex] is the same as [tex]\log_{10}(3a)=n[/tex]
The base is 10 (if you don't see a base and log is written).
The exponent is n.
So we have [tex]10^n=3a[/tex].
To transform the logarithmic function log3 a = n into an exponential form, we apply the rule that if logb a = n, then b^n = a. Therefore, the exponential form is 3^n = a.
Explanation:The student's question is about transforming a logarithmic equation into an exponential form. This is a common request in mathematics, particularly in algebra and precalculus.
The given equation is log3 a = n. The exponential form of a logarithmic equation is based on this relationship: If logba = n, then the exponential form is bn = a. Applying this rule to the provided equation gives 3n = a as the exponential form.
This transformation is based on the definition of logarithms, which are the inverses of exponential functions. The logarithm of a number to a particular base is the exponent to which the base must be raised to get that number. So in this case, n is the power you need to raise 3 to in order to get a.

Tom just received a new job offer. He is told that his starting salary will be $75,000 per year. He is told his salary will probably be $81,000 in four years. We'll use this information to try to anticipate his future earnings in any given year.Assume that Y= Tom's salary amount in dollars and x= the number of years worked. Step 1.Use the data given to find the rate of change, or the salary increase per year.( hint: compute the slope.) We are now going to use a line to model Tom's salsry growth. Step 2. Use the data given and the slope value from Step 1 to write the slope-intercept form of the line. Step 3. Based on your equation from Step 2, What will Tom's salary be in ten years?
Answer:
Part 1) The rate of change is [tex]2,000\ \$/year[/tex]
Part 2) The equation of the line into slope intercept form is [tex]y=2,000x+73,000[/tex]
Part 3) Tom's salary would be [tex]\$93,000[/tex] in ten years
Step-by-step explanation:
Let
x ------> the number of years worked
y -----> Tom's salary amount in dollars
we have the points
A(1, 75,000) and B(4,81,000)
step 1
Find the rate of change (slope)
The slope is equal to
[tex]m=(81,000-75,000)/(4-1)=2,000\ \$/year[/tex]
step 2
Find the equation of the line into slope-intercept form
we know that
[tex]y=mx+b[/tex]
where
m is the slope
b is the y-intercept
we have that
[tex]m=2,000\ \$/year[/tex]
point A(1, 75,000)
substitute
[tex]75,000=(2,000)(1)+b[/tex]
[tex]b=75,000-2,000=73,000[/tex]
The equation of the line is
[tex]y=2,000x+73,000[/tex]
step 3
What will Tom's salary be in ten years?
For x=10 years
Substitute in the linear equation
[tex]y=2,000(10)+73,000=\$93,000[/tex]
Answer:
The increment in salary is $1500 each year. The slope intercept form is [tex]y=1500x+75000[/tex] and the salary in 10 years will be $90000.
Step-by-step explanation:
Consider the provided information.
The starting is $75,000 per year.
Let x is the number of years worked and y is Tom's salary amount in dollars.
When he has 0 yr of experience, his salary is $75000 per year.
it can be written as (0,75000).
His salary will probably be $81,000 in four years.
It can be written as (4,81000).
STEP 1:
Find the rate of change by using the formula slope=[tex]m=\frac{rise}{run}[/tex].
Determine the rise by subtracting 75000 from 81000.
Rise = 81000 - 75000 = 6000
Now determine the run by subtracting 0 from 4.
Run = 4 - 0 = 4
Substitute the respective values in the above formula.
[tex]slope=m=\frac{6000}{4}\\slope=m=1500[/tex]
Therefore, the rate of change, or the salary increase per year is $1500.
STEP 2:
Write the slope intercept form by using the formula:
[tex](y-y_1)=m(x-x_1)[/tex]
Substitute m = 1500 and [tex](x_1,y_1)=(0,75000)[/tex] on the above formula.
[tex](y-75000)=1500(x-0)\\y-75000=1500x\\y=1500x+75000[/tex]
Thus, the slope intercept form is [tex]y=1500x+75000[/tex].
STEP 3:
The salary in 10 years. can be calculated as:
Substitute the value of x = 10 in [tex]y=1500x+75000[/tex].
[tex]y=1500(10)+75000\\y=15000+75000\\y=90000[/tex]
Hence, the salary in 10 years will be $90000.

Answer: [tex]x=1[/tex]
Step-by-step explanation:
In order to find the value of "x", it is important to remember that:
[tex]Tangent\ chord\ angle=\frac{1}{2}(Intercepted\ arc)[/tex]
We can identify in the figure that:
[tex]Tangent\ chord\ angle=(43x)\°\\\\Intercepted\ arc=AB[/tex]
Then:
[tex]43x=\frac{1}{2}AB[/tex]
Solving for AB:
[tex]2(43x)=AB\\\\AB=86x[/tex]
Now, since there are 360° in a circle, we know that:

Final answer:
The cost of 2.50 pounds of bananas is 1.50 dollars.
Explanation:
To find the cost of 2.50 pounds of bananas, we need to multiply the weight of the bananas by the cost per pound. In this case, the cost per pound is 60 cents.In the store, bananas cost 60 cents per pound, and the cost in dollars for x pounds of bananas is given by the equation 0.6x. To find the cost of 2.50 pounds of bananas, you simply substitute x with 2.50 in the equation: 0.6 times 2.50. So, we multiply 2.50 pounds by 0.60 dollars per pound:
2.50 pounds x 0.60 dollars/pound = 1.50 dollars.
Therefore, the cost of 2.50 pounds of bananas is 1.50 dollars.

Answer:
1. C) 5.50x + 10
2. 54
Step-by-step explanation:
1. C) 5.50x + 10
You have a static fee of $10 which does not need to be attached to a variable as it will not change. You also have a fee of $5.50, which may be charged depending on the amount of classes. Since this is dependent on something, it includes a variable.
Therefore, your terms are:
5.5x
10
Simply add them together for your equation.
[tex]5.5x+10[/tex]
2. 54
To solve, simply plug in 8 to your equation which you created in part 1. This is possible because x stands for the amount of classes and, as the question tells us, 8 is the amount of classes.

Consider the function represented by the equation x - y = 3. What is the equation written in function notation, with x as the
ndependent variable?
O f(x) = y + 3
Of(x) = -y-3
Of(x) = -x + 3
f(x) = X-3
Answer:
f(x)=x-3
Step-by-step explanation:
You are given x-y=3 and you want to rewrite in function notation with x being the independent. That means we need to solve for y so y can depend on x.
x-y=3
Subtract x on both sides:
-y=-x+3
Multiply both sides by -1:
y=x -3
So function notation would be f(x)=x-3
The function notation of the equation x - y = 3, with x as the independent variable, is f(x) = x - 3.
Explanation:The equation x - y = 3 is in standard form. To express this equation in function notation with x as the independent variable, we need to solve for y in terms of x. By moving y to the other side of the equation and 3 to the opposite side, we get y = x - 3. In function notation, where y is usually replaced by the function f(x), the equation becomes f(x) = x - 3.

Find the arc length of the given circle.
Answer:
Arc length = (30/360)(2π)(14)

Given a triangle with a = 12, A = 13°, and B = 12°, what is the length of c? Round to the nearest tenth.
Answer:
=5.1 units
Step-by-step explanation:
To use the sine rule to find the length of c we first need to find the angle at C.
C=180-(13+12)
C=180-25
C=155°
a/Sin A=c/Sin C
Calculating for the value of c using the sine rule:
12/Sin 13=c/Sin 155
c=12 sin 155
=5.07 units
Thus to 1 decimal places, the value of c is 5.1 units.

Solve this equation for x. Round your answer to the nearest hundredth. 0.75=logx
Answer:
Step-by-step explanation:
[tex]10^.^7^5=10^l^o^g^(^x^)\\=10^.^7^5=x\\=10^\frac{3}{4}=\sqrt[4]{10^3} =\sqrt[4]{1000} =5.6=x[/tex]
To solve the equation 0.75 = log(x), we exponentiate both sides with base 10, resulting in x = 10^0.75. The calculated value of x to the nearest hundredth is approximately 5.62.
Explanation:To solve the equation 0.75 = log(x), we need to understand that the logarithm function here is the common logarithm, which means it has a base of 10. The equation essentially states that 10 raised to the power of 0.75 equals x. To find x, we simply need to perform the inverse operation of taking the logarithm, which in this case is exponentiation.
We use the fact that if logb(a) = c, then bc = a, where b is the base, a is the result, and c is the exponent. Therefore, we can rewrite our original equation as:
x = 100.75
Using a calculator, we can find that:
x ≈ 5.62
This is the value of x, rounded to the nearest hundredth, as the question requested.

n = 29, n + 1 = 30. n + 2 = 31
Dn+n + 2 +n + 4-87;
n = 29,0 + 2 = 31, n + 4 = 33
Answer:
A
n=27, n+2=29, n+4=31
The correct option is A: n + n + 2 + n + 4 = 87; n -27, n + 2 - 29, n + 4 - 31.
Let's denote the three consecutive odd integers as n, n + 2, and n + 4. The sum of these integers is given as 87.
The correct equation to represent this situation is:
n + (n + 2) + (n + 4) = 87
Now let's solve for n:
3n + 6 = 87
Subtract 6 from both sides:
3n = 81
Divide both sides by 3:
n = 27
n + (n + 2) + (n + 4) = 87
27 + 29 + 31 = 87
The three consecutive odd integers are 27, 29, and 31.

At the carpet store where you work, a customer wants to buy carpet for a room that is 16 1/2 feet by 18 1/2 feet in size. The carpet ,pad,and installation will cost $17.50 per square yard. To the nearest dollar,how much will it cost to carpet the room?
Answer: 595 Dollars
Step-by-step explanation:
16 1/2 times 18 1/2 = 305.25
one square yard = nine feet
305 devided by nine 33.9166667 (round to 34)
34 times 17.50 = 595
Answer:
$593
Step-by-step explanation:
We have been that a customer wants to buy carpet for a room that is 16 1/2 feet by 18 1/2 feet in size.
First of all, we will find area of carpet by multiplying both side lengths as:
[tex]\text{Area of carpet}=16\frac{1}{2}\text{ ft}\times 18\frac{1}{2}\text{ ft}[/tex]
Convert mixed fraction into improper fraction:
[tex]16\frac{1}{2}\Rightarrow \frac{16\times2+1}{2}=\frac{32+1}{2}=\frac{33}{2}[/tex]
[tex]18\frac{1}{2}\Rightarrow \frac{18\times2+1}{2}=\frac{36+1}{2}=\frac{37}{2}[/tex]
[tex]\text{Area of carpet}=\frac{33}{2}\text{ ft}\times \frac{37}{2}\text{ ft}[/tex]
[tex]\text{Area of carpet}=\frac{1221}{4}\text{ ft}^2[/tex]
[tex]\text{Area of carpet}=305.25\text{ ft}^2[/tex]
1 square feet equals 0.111 square yards.
[tex]305.25\text{ ft}^2=305.25*0.1111\text{ yards}^2[/tex]
To find the cost to carpet the room, we will multiply area of carpet by cost $17.50 per square yards.
[tex]305.25\times 0.1111\text{ yards}^2\times\frac{\$17.50}{\text{ yard}^2}[/tex]
[tex]305.25\times 0.1111\times\$17.50[/tex]
[tex]\$593.4823125\approx \$593[/tex]
Therefore, the cost to carpet the room would be $593.

where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of [tex]y[/tex] when [tex]x=0[/tex]).
The information that we have is that the slope of the line is:
[tex]m=\frac{4}{5}[/tex]
and that the line crosses the y-axis at (0, 1).
From this point we can find the y-intercept [tex]b[/tex], because b is the value of [tex]y[/tex] when [tex]x=0[/tex].
And since the line passes through (0, 1) when [tex]x = 0[/tex], [tex]y =1[/tex]. Thus, the y-intercept is:
[tex]b=1[/tex]
substituting the values of the slope and the y-intercept into the equation:
[tex]y=mx+b\\y=\frac{4}{5}x+1[/tex]
the answer is: [tex]y=\frac{4}{5}x+1[/tex]
What is the first term in this expansion?
1.) 2x^15
2.) 2^15x^15
3.) 10y^15
4.) 10^15y^15
Answer:
2¹⁵x¹⁵ (2nd option)
Step-by-step explanation:
When you expand (2x+10y)¹⁵ you would get:
32,768x¹⁵ + 2,457,600x¹⁴y + 86,016,000x¹³y² + 1,863,680,000x¹²y³+
27,955,200,000x¹¹y⁴+307,507,200,000x¹⁰y⁵ + 307,507,200,000x¹⁰y⁵ + ... so on and so forth.
Since you are not interested in anything else but the first term, observe that the first term is:
32,768x¹⁵
That is equal to: 2¹⁵x¹⁵
What happened there is you need to distribute the exponent to the coefficient of the term as well, so you need to distribute it to 2 as well.
