A rectangular porch has dimensions of (2x+3) feet and (x+9) feet. the area of the porch is 500 square feet. what are the length and width of the porch?

Answers

Answer 1

Answer:

The dimensions of the porch are [tex]25\ ft[/tex]  by [tex]20\ ft[/tex]

Step-by-step explanation:

we know that

The area of the porch is equal to the length multiplied by the width

[tex]A=(2x+3)(x+9)[/tex]

[tex]A=500\ ft^{2}[/tex]

so

[tex]500=(2x+3)(x+9)[/tex]

Solve for x

[tex]500=2x^{2} +18x+3x+27\\ \\2x^{2} +21x-473=0[/tex]

Solve the quadratic equation by graphing

The solution is [tex]x=11\ ft[/tex]

see the attached figure

The dimensions are

[tex](2x+3)=2(11)+3=25\ ft[/tex]

[tex](x+9)=11+9=20\ ft[/tex]

compressed vertical by a factor of 2

translated left 2 units

translated right 2 units

compressed horizontal by a factor

Answers

Answer:

translated left by 2 units

Step-by-step explanation:

Given y = f(x) then

y = f(x ± a) represents a horizontal translation of a units

• If + a then a shift of a units to the left

• If - a then a shift of a units to the right

Hence

g(x) is the graph of f(x) translated 2 units to the left

Final answer:

The function g(x) = (x+2)^2 + 1 is a transformation of the function f(x) = x^2 + 1. It represents a translation of the graph of f(x) to the left by 2 units.

Explanation:

The function g(x) = (x+2)^2 + 1 is a transformation of the function f(x) = x^2 + 1. Particularly, it's a horizontal shift, not a compression or stretching of the graph. By comparing coefficients, we infer that the +2 inside the parentheses on g(x) represents a shift of the graph of f(x) to the left by 2 units. This is because the rules of transformations dictate that h(x) = (x - h)^2, where h represents a shift to the right, and h(x) = (x + h)^2 represents a shift to the left. Therefore, the correct statement is that the graph of g(x) is translated left 2 units compared to the graph of f(x).

Does anyone know the answer to this question:This histogram shows the numbers of shoppers in various age groups at a clothing store. How many shoppers are at least 20 years old? I WILL MARK BRAINLIEST! PLEASE HURRY!!!!!!!! I NEED AN ANSWER RIGHT NOW!!! IM BEGGING YOU!!!

a: 7
b: 12
c: 13
d:18

Answers

There are 13 shoppers aged 20 or older. Calculated by summing frequencies of age groups 20-24 through 35-39. Answer: (c) 13.

Of course, I'm happy to help! To find out how many shoppers are at least 20 years old, we need to add up the frequencies of the age groups that are 20 years old and older. Here are the steps:

1. Identify the age groups that are 20 years old and older.

2. Add up the frequencies (the number of shoppers) for those age groups.

Let's assume the histogram provides age groups in 5-year intervals, starting from 0 to 4 years old, then 5 to 9 years old, and so on.

Let's look at the age groups that are at least 20 years old:

1. 20-24 years old

2. 25-29 years old

3. 30-34 years old

4. 35-39 years old

5. 40-44 years old

We add up the frequencies for these age groups:

1. Frequency for 20-24 years old: 5

2. Frequency for 25-29 years old: 4

3. Frequency for 30-34 years old: 3

4. Frequency for 35-39 years old: 1

5. Frequency for 40-44 years old: 0 (since it's not specified in the histogram, we assume it's 0)

Adding these frequencies together:

5 + 4 + 3 + 1 + 0 = 13

So, there are 13 shoppers who are at least 20 years old.

The answer is (c) 13.

How fast is a train going that makes a 330 mile trip in 4 hours?

Answers

A traffic camera sits on top of a tower that has a height of 50ft., the angles of depression of two cars on a straight road at the same level as that of the base of the tower and on the same side of it are 25° and 40°. Calculate the distance between two cars

Answers

Answer:

[tex]\boxed{\text{48 ft}}[/tex]

Step-by-step explanation:

The angle of depression from the camera at D and the angle of elevation from the target cars are congruent.

1. Distance of car A from tower

Consider ∆ACD

tan25 = 50/AC

AC  = 50/tan25 = 50/0.4663 = 107.2 ft

2. Distance of car B from tower

Consider ∆BCD

tan40 = 50/BC

AC  = 50/tan40 = 50/0.8391 = 59.6 ft

3. Distance from cars A and B

AB = AC – BC = 107.2 – 59.6 = 48 ft

The distance between the two cars is [tex]\boxed{\textbf{48 ft}}[/tex].

It took Jason 3 minutes and 48 seconds to complete a practice page in class. How many total seconds did Jason take to complete the practice page?

Answers

with the current weather conditions a sailboat can sail 5 1/2 miles in an hour.How far can a sailboat sail in 2/3 hours​

Answers

Answer:

3  2/3 miles

Step-by-step explanation:

distance = rate times time.

Here,

distance = (5.5 mph)(2/3 hr) = 3  2/3 miles

The sailboat can travel 3 2/3 miles in 2/3 hours by multiplying the speed (5 1/2 miles per hour) by the time (2/3 hours) to get the distance.

To determine how far a sailboat can sail in 2/3 hours when it can sail 5 1/2 miles in one hour, we need to perform a multiplication of the speed by the time. The speed of the sailboat is 5 1/2 miles per hour (which is the same as 11/2 miles per hour in improper fraction form), and the time is 2/3 hours.

Here are the steps to calculate the distance:

Convert 5 1/2 miles to an improper fraction: 5 1/2 = (5 times 2 + 1)/2 = 11/2.

Multiply the speed by the time: (11/2) times (2/3) = (11 times 2)/(2 times 3) = 22/6.

Simplify the fraction: 22/6 = 11/3 = 3 2/3 miles.

Therefore, the sailboat can travel 3 2/3 miles in 2/3 hours.

The short leg is 7 because half of 14 is 7 and the hypotenuse is always twice as long as the shortest one.

The required short leg is 7inches.

Given that,

Hypotenuse = 14 inches,

In triangle 30-60-90

We have to determine,

By using figure find the short leg.

According to the question,

A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º.

The triangle is special because its side lengths are always in the ratio of 1: √3:2.

The 30-60-90 triangle rule is for finding the the lengths of two sides when one side is given.

The shorter side is opposite the 30 degree angle, the longer side is opposite the 60 degree angle, and the hypotenuse is opposite the 90 degree angle.

Therefore,

The hypotenuse is always twice as long as the shortest one.

Where, Hypotenuse = 14inches

Then,

[tex]Hypotenuse = 2 \times short \ leg \\\\14 = 2 \times short \ leg\\\\short\ leg = \dfrac{14}{2}\\\\short \ leg = 7[/tex]

Find the slope of a line parallel to 2x-y=18

Answers

Answer:

The slope of line parallel to 2x-y = 18 will be 2.

Step-by-step explanation:

Given  

The equation of a line : 2x – y = 18

The standard form of an equation of a line in slope-intercept form is:

y=mx+c

So, we will have to convert the given equation in the standard form.

2x-y=18

-y=-2x+18

-y= -(2x-18)

y=2x-18

The coefficient of x in this form is the slope of the line.

So,

m_1=2

We know that slopes of two parallel lines are equal so if the given line has slope 2, all the lines parallel to this line have slope 2..

For this case, we have by definition, if two lines are parallel then their slopes are equal:

[tex]m_ {1} = m_ {2}[/tex]

We have the following equation:[tex]2x-y = 18[/tex]

We rewrite the equation of the form:

[tex]y = mx + b\\2x-18 = y\\y = 2x-18[/tex]

Thus, a parallel line will have a slope [tex]m_ {2} = 2[/tex]

A classroom has more boys than girls, and it has 8 girls. Furthermore, each student in the classroom has at least 2 pencils. Let b represent the number of boys and let p represent the total number of pencils in the classroom.Let's compare the expressions p and 30. Which statement is correct?

Answers

Answer:

Choices are:

p>30

p<30

p=30

not enough information to tell

Answer is p>30

Step-by-step explanation:

Since there are more boys than girls, there must be at least 9 boys.  Plug into equation:  (b+8) represents number of students.  If they each have at least 2 pencils we would use 2(b+8).  Plugging in  9 for the boys we have: 2(9+8)=?

2(17)=34.  So with the minimum number of boys there would be at least 34 pencils, so the answer is p>30

Final answer:

By calculating that p equals 2 times the sum of boys and girls, and that there are at least 9 boys, we find that p (the total number of pencils) must be greater than 30.

Explanation:

To compare the expressions p and 30, let us first define p as the total number of pencils. Since there must be more boys than girls and there are 8 girls, let b represent the number of boys. We can say that b > 8, since there are more boys than girls.

It's also given that each student has at least 2 pencils. Therefore, the minimum total number of pencils p can be calculated by multiplying the total number of students by 2.

This gives us p = 2(b + 8). Because b > 8, let's substitute the minimum number for boys (9), so p = 2(9 + 8) = 34.

Therefore, p > 30.

Answer:

(x + 12)(x + 2)

Step-by-step explanation:

In order to factorize, we first have to break the term in the middle into two terms which add up to 14 and and multiply to 24.

For this, let's take a look at the factor pairs of 24. We have (1, 24), (2,12), (3, 8), (4, 6).

note that the 2nd pair works. 2 + 12 = 14, 2*12 = 24.

And now we rewrite the expression.

x^2 + 14x + 24

= x^2 + 12x + 2x + 24

Take out common factors as below

= x(x + 12) + 2(x + 12)

Note that (x+12) is a common factor in the 2 added expressions. So we take it out.
