A triangle is drawn on the coordinate plane. It is translated 4 units right and 3 units down. Which rule describes the translation?

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.

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.

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.

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.

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:

[tex]AB+(272x+2)=360[/tex]

Then we can substitute [tex]AB=86x[/tex] into [tex]AB+(272x+2)=360\°[/tex] and solve for "x". This is:

[tex](86x)+(272x+2)=360\\\\358x=360-2\\\\x=\frac{358}{358}\\\\x=1[/tex]

Answer:

Shift +2 units to the right and +2 units up

Step-by-step explanation:

y = (x+3)² + 4 has a horizontal shift of -3 and a vertical shift of +4.

y = (x+1)² + 6 has a horizontal shift of -1 and a vertical shift of +6.

So do translate the first equation to the second, shift +2 units to the right and +2 units up.

Answer:

=11.155 in³

Step-by-step explanation:

Given data:

Radius= 1.75 inches

Height = 3.5 inches

Diameter= 0.5 inches

To find the volume of a cone we will apply the formula:

Volume of a cone = 1/3 πr²h

Substitute the values:

V= 1/3* 3.14 *(1.75)² * 3.5

V=1/3 *3.14*(3.0625)* 3.5

V= 33.66/3

V=11.22 in³

Now find the volume of the bubble gum:

Volume of bubble gum = 4/3 π*r³

Substitute the values:

V= 4/3*3.14*(0.5/2)³

V=4/3*3.14(0.25)³

V=4/3*3.14(0.015625)

V=0.19625/3

V=0.0654 in³

Now subtract the volume of bubble gum ball from the volume of a cone

=11.22 - 0.0654

=11.155 in³

Thus the closest approximation of the volume of the cone that can be filled with flavored ice is 11.155 in³....

Answer:

Only the function represented by graph 2 has an inverse function

Step-by-step explanation:

* Lets explain the inverse of the function

- The Function is a relation between x-coordinates and the y-

 coordinates of the order pairs under the condition every

 x-coordinate has only one y-coordinate

- Ex: R = {(2 , 3) , (1 , 5) , (-2 , -3)} is a function because every x-

 coordinate has only one y-coordinate and R = {(2 , 3) , (-1 , 4) ,

 (2 , 5)} not a function because the x-coordinate 2 has two y-

 coordinates 3 and 5

- We use the vertical line to test the graph is function or not, if

 the vertical line intersects the graph in one point then the

 graph is function if intersects it in more than one point then the

 graph is not function

- We have two types of function one-to-one function and

 many-to-one function

# one-to-one function means every x-coordinate has only 1 y-coordinate

# many-to-one function means some x-coordinates have only 1

  y-coordinate

- We find the inverse function by switching x and y, then one-to-

 one function has inverse but many-to-one has not inverse

 because when we switched x and y it will be one-to-many

 means one x-coordinate has many y-coordinates and this is not

 a function

- We use the horizontal line to test the graph of the function has

 inverse or not, if the horizontal line intersects the graph in one

 point then the function of the graph has inverse if it intersects

 the graph in more than one point ,then the function of the  

 graph has no inverse

* Now lets test all the graphs by using the horizontal line

# graph 1

∵ The horizontal line cuts the graph in more than 1 point

∴ The function of graph 1 has no inverse

# graph 2

∵ The horizontal line cuts the graph in just 1 point

∴ The function of graph 2 has inverse

# graph 3

∵ The horizontal line cuts the graph in more than 1 point

∴ The function of graph 3 has no inverse

# graph 4

∵ The horizontal line cuts the graph in more than 1 point

∴ The function of graph 4 has no inverse

* Only the function represented by graph 2 has an inverse function

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.

Answer:

1 1/5 mi

Step-by-step explanation:

We need to add the three legs together

3/10 + 1/2 + 2/5

The common denominator is 10

3/10  =3/10

1/2 *5/5 = 5/10

2/5 *2/2 =4/10

3/10 + 5/10+4/10 = 12/10

10/10 = 10/10+2/10 = 1+2/10  = 1 1/5 mi

Answer:

Length of race = 1.2 miles

Step-by-step explanation:

Length of race is given by the perimeter of triangle.

Refer the given figure.

The first leg is 3/10 mi, the second leg is 1/2 mi, and the third leg is 2/5 mi.

[tex]\texttt{Perimeter =}\frac{3}{10}+\frac{1}{2}+\frac{2}{5}=\frac{3}{10}+\frac{5}{10}+\frac{4}{10}=\frac{3+5+4}{10}\\\\\texttt{Perimeter =}\frac{12}{10}=1.2 miles[/tex]

Length of race = 1.2 miles

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.

Statement C can be combined with its converse to form a true biconditional because both statements are true.

In order for a statement and its converse to form a true biconditional, both statements must be true. Let's analyze the given statements:

A) If the measure of an angle is 30, then it is an acute angle.

B) If two lines intersect, then the two lines are not skew.

C) If the ray is the perpendicular bisector of the segment, then it divides the segment into two congruent segments.

D) If an angle is a straight angle, then its sides are opposite rays.

Out of these options, statement C can be combined with its converse to form a true biconditional because both statements are true:

If the ray is the perpendicular bisector of the segment, then it divides the segment into two congruent segments.

If the segment is divided into two congruent segments, then the ray is the perpendicular bisector of the segment.

Answer:

Arc length = (30/360)(2π)(14)

= (7/3)π cm = about 7.33 cm

Final Answer:

The direct distance from point A to point B, considering a straight path through the pond, is 80 meters. This is obtained by applying the Pythagorean theorem to the right-angled triangle formed by walking 23 meters and then 57 meters along the edges of the pond. Subtracting the initial 23 meters provides the actual direct distance.

Step-by-step explanation:

In this scenario, we can apply the Pythagorean theorem to find the direct distance from point A to point B. Let's denote the sides of the right-angled triangle formed by walking along the edges of the pond as follows: the first leg (along one edge) is \(a = 23\) meters, the second leg (along the other edge) is [tex]\(b = 57\)[/tex] meters, and the hypotenuse (direct distance from A to B, walking through the pond) is (c). According to the Pythagorean theorem, [tex]\(c^2 = a^2 + b^2\).[/tex]

Substituting the given values, we get [tex]\(c^2 = 23^2 + 57^2\).[/tex] Calculating this gives [tex]\(c^2 = 529 + 3249\)[/tex], resulting in [tex]\(c^2 = 3778\)[/tex]. Taking the square root of both sides gives [tex]\(c ≈ \sqrt{3778} ≈ 61.47\)[/tex]. Therefore, the direct distance from point A to point B, walking through the pond, is approximately 61.47 meters.

However, since the question asks for the distance considering walking straight through the pond, we need to add the lengths of both sides of the pond. Thus, [tex]\(61.47 + 23 + 57 = 80\)[/tex]. Therefore, the final answer is 80 meters. This approach considers the direct path, incorporating the lengths of the edges and the hypotenuse, providing the most accurate measurement for the distance from point A to point B.

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.

[tex]5.5(8)+10\\44+10\\54[/tex]

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.

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.

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.

The following features of the triangle are found: A. a² + b² - c² = 2 · a · b · cos θ, B. cos θ < 0, C. The triangle is not a right triangle.

How to analyze the features of a triangle

In this question we must infer all features from a triangle such that a² + b² < c². Then, the triangle is not a right triangles since relationship between side lengths is different from the relationship described by Pythagorean theorem. Then, triangle is described by law of cosine:

a² + b² - c² = 2 · a · b · cos θ

If a² + b² < c², then a² + b² - c² < 0 and 2 · a · b · cos θ < 0. Thus, we get the following result: cos θ < 0.
