What is the equation, in point-slope form, of the line that is perpendicular to the given line and passes through the point (2, 5)?

y + 5 = x + 2
y − 2 = x − 5
y − 5 = −(x − 2)
y + 2 = −(x + 5)

Answers

We are given point (2,5).

We need to find the equation of line perpendicular to the given line and passes through the point (2, 5).

We know point-slope form :

y-y1 = m(x-x1).

Plugging values of (x1,y1) = (2,5) in above slope-intercept form, we get

y - 5 = m(x-2).

Which matches 3rd option y − 5 = −(x − 2).

So, the correct option is y − 5 = −(x − 2).

Answer:

Step-by-step explanation:

Given: ABCD is a parallelogram m∠A = 60º ; BK ⊥ AD AK = KD; Perimeter of ABCD = 24 Find: BD.

Answers

Since AK =  KD, then the triangle ABD is isosceles,
Then BD = AB. Denote AB by x and AK by y. 
Then, 
2x+4y=24 (the perimeter)
cos 60=y/x. 
From the second equation we get [tex]y=0.5x[/tex]
Plug in the first equation we get: 
[tex]2x+4(0.5x)=24\\2x+2x=24\\4x=24\\x=6[/tex]
We deduce that [tex]BD=6.[/tex]

Final answer:

To find BD, we can use the fact that the opposite sides of a parallelogram are equal in length. The length of BD is 4.8 units.

Explanation:

In the given problem, we have a parallelogram ABCD with m∠A = 60º. BK is perpendicular to AD and AK = KD. The perimeter of ABCD is 24. To find BD, we can use the fact that the opposite sides of a parallelogram are equal in length. Since AK = KD, the length of AD is twice the length of AK.

Let AK = x. Then AD = 2x. The perimeter of ABCD is given by P = AB + BC + CD + AD. Substituting the given values, we have 24 = AB + BC + CD + 2x. We know that AB = CD, so the equation becomes 24 = 2AB + 2BC + 2x. Rearranging the terms, we get AB + BC + x = 12.

Using the fact that opposite sides of a parallelogram are equal in length, we can deduce that BC = AB. Substituting this into the equation, we have 2AB + AB + x = 12. Simplifying, we get 3AB + x = 12. Since AK = KD, we have x = KD. Substituting this into the equation, we have 3AB + KD = 12. Since AK = KD, we have 3AB + AK = 12. Since AK = KD, we have 3AB + 2AK = 12. Simplifying, we get 3AB + 2AB = 12. Combining like terms, we get 5AB = 12. Dividing both sides by 5, we get AB = 12/5. Since AB = CD, we have CD = 12/5. Since opposite sides of a parallelogram are equal in length, we have BD = AD = 2x = 2(12/5) = 24/5 = 4.8.

A bedroom is 15 ft long and 12 ft wide. How much will it cost to carpet the room if carpeting coats $22 per square foot. (1 yd=3 ft)

Answers

You know the cost per square foot of carpet and the dimensions of the bedroom; to find the cost of carpeting the entire room, first determine its area.

A = bh
A = 15(12)
A = 180

The area of the bedroom is 180 square feet. The cost of carpeting the entire bedroom will be the amount of square feet of the bedroom (its area) times the cost per square foot of carpet. Multiply the area by the cost per square foot.

180 × 22 = 3960

It will cost $3,960 to carpet the bedroom.

Answer:

C. p → q

Step-by-step explanation:

We are given that,

'p' is represented by 'x = 4' and 'q' is represented by 'y = -2'.

That is, we have,

p: x = 4

q: y = -2

The given statement is, 'If x = 4, then y = -2'.

This means that whenever x = 4, then y = -2.

That is, 'x = 4 implies y = -2'.

Thus, it will be represented by p → q.

The sum of two numbers is 52. If twice the smaller number is subtracted from the larger number, the result is 13. Find the two numbers.

Answers

To solve this equation, you know you have two numbers which you can represent with x and y. 
Larger number = y         Twice the smaller number subtracted from the larger
Smaller number = x       is equal to 13:

y - 2x = 13      Solve for y:    y = 2x + 13      Then substitute your value for y into the equation they gave you at the beginning:

(2x + 13) + x = 52    Solve the equation by simplifying:
3x = 52 - 13       3x = 39    x = 13           Then substitute your value for x (13) into the equation we made to solve for y:
y - 2(13) = 13      y - 26 = 13     y = 39     
So your answer is, "The two numbers are 13 and 39."

You estimate the distance from your house to your school to be 1.6 miles. The actual distance is 1.9 miles. Find the percent error. Round your answer to the nearest tenth of a percent.

Answers

To find percent error you use the following formula:
[tex]% Error = \frac{final value - given value}{given value} [/tex]
% error = (1.6 - 1.9)/1.9 * 100% = 15.79%

Final answer:

The percent error of the estimated distance from your house to school is 15.8% when rounded to the nearest tenth.

Explanation:

To find the percent error of your estimate, you use the formula:

Error = (|Estimated value - Actual value| / Actual value) × 100

Plugging the values from your question:

Error = (|1.6 miles - 1.9 miles| / 1.9 miles) × 100

Error = (|-0.3 miles| / 1.9 miles) × 100

Error = (0.3 miles / 1.9 miles) × 100

Error = 0.15789473684 × 100

Error = 15.789473684%

When rounded to the nearest tenth of a percent, the percent error is 15.8%.

what function is vertically stretched by a factor of 3 and translated 4 units right from the parent function
A. log_(5) (3x+4)
B. 3log_(5) (x-4)
C. 3(5^x+4)
D. 5^3x-4

Answers

Final answer:

The correct function is B, 3log_5(x-4), which represents a logarithmic function that is vertically stretched by a factor of 3 and translated 4 units to the right.

Explanation:

The student is asking about transformations of a parent function, specifically a vertical stretch and a horizontal translation. When a function is vertically stretched by a factor of 3, this involves multiplying the function by 3. A translation of 4 units to the right would mean adjusting the input variable x by subtracting 4. Considering the options given, option B, 3log5(x-4), is the correct answer because it represents a function that has been vertically stretched by a factor of 3 and horizontally translated 4 units to the right from its parent function log5x.

A wall map has a scale of 128 miles = 6 inches. The distance between Springfield and Lakeview is 2 feet on the map. What is the actual distance between Springfield and Lakeview? Question 4 options: 42.7 miles 1.13 miles 512 miles 384 miles

Answers

To find the actual distance you will convert the 2 feet to inches because the scale is given in miles to inches.

2 feet = 24 inches

128 miles/6 inches is the scale.

I would create an equivalent ratio using this scale and the 24 inches.

128 miles/6 inches=x miles/24 inches

To go from 6 inches to 24 inches, you will need 4 groups of 6 inches.

You would also need 4 groups of 128 miles.

4 x 128 = 512 miles

The distance between these 2 towns is 512 miles.

Solve this equation: 3x-1/5-2/9x=124/5
Step 1: Simplify by combining like terms. Which terms can be combined?
A) 3x and -1/5
B) -1/5 and -2/9x
C) 3x and -2/9x

Answers

Answer:

The correct option is C.

Step-by-step explanation:

The given equation is

[tex]3x-\frac{1}{5}-\frac{2}{9}x=\frac{124}{5}[/tex]

If two terms have the same variables having same powers, then they are known as like terms.

In the given equation [tex]3x[/tex] and [tex]-\frac{2}{9}x[/tex] are like terms.

So, when we simplify the given equation by combining like terms. we need to combined [tex]3x[/tex] and [tex]-\frac{2}{9}x[/tex] .

Therefore the correct option is C.

The solution to the equation is approximately x = 45.48.

To solve the equation 3x - 1/5 - 2/9x = 124/5,  to combine like terms. Like terms are terms that have the same variable and exponent.

The terms in the equation are:

3x (coefficient is 3, and the variable is x)

-1/5 (coefficient is -1/5)

-2/9x (coefficient is -2/9, and the variable is x)

Now, let's identify the like terms that  combined:

C) 3x and -2/9x

The terms 3x and -2/9x both have the variable x, so they are like terms and can be combined.

Step 1: Combine the like terms:

3x - 2/9x = (3 - 2/9)x = (27/9 - 2/9)x = (25/9)x

Now, after combining the like terms, the equation becomes:

(25/9)x - 1/5 = 124/5

Step 2: Isolate x on one side of the equation. To do this, we can first get rid of the fraction by multiplying the entire equation by the least common multiple (LCM) of the denominators, which is 45 (LCM of 9 and 5):

45 × [(25/9)x - 1/5] = 45 × (124/5)

This simplifies to:

25x - 9 = 1128

Step 3: Now, isolate x by moving the constant term (-9) to the other side of the equation:

25x = 1128 + 9

25x = 1137

Step 4: Finally, divide by 25 to solve for x:

x = 1137 / 25

x ≈ 45.48
