Find the length of a rectangle given that the perimeter is 32 feet and the length is 1 foot more than four times the width.

Answer:

f(0)=2

Step-by-step explanation:

f(x)=-3x +2

f(0)=-3(0) +2

f(0)= 0 +2

f(0)=2

[tex]\\ \tt\hookrightarrow f(x)=\dfrac{x^2}{x-6}[/tex]

Find inverse

[tex]\\ \tt\hookrightarrow y=\dfrac{x^2}{x-6}[/tex]

[tex]\\ \tt\hookrightarrow x=\dfrac{x^2+6y}{y}[/tex]

[tex]\\ \tt\hookrightarrow f'(x)=\dfrac{x^2+6x}{x}=x+6[/tex]

Now

Answer:

#5 more info is needed. #6 is a CD.

Step-by-step explanation:

#5 doesn't have the appropriate values given which in this case is how much money. #6 is most likely a CD because they tend to have bigger interest rates, unless if you needed to access it. If you needed to access this money, a savings account would most likely give you the best interest rates.

Answer:

We want to multiply two polynomials of degree 1, and get in that way a polynomial of degree 2.

We will get the polynomial: p(x) = 2 * x² + 2 * x - 12

Step-by-step explanation:

We just want to multiply (x + 3) and (2*x - 4).

So we start by writing:

(x+3) * (2*x-4)

Now we just expand this:

(x+3) * (2*x-4) = 2 *  x² + x * (-4) + 3 * (2 * x) + 3 * (-4)

Now we need to simplify the above expression:

2 * x² + x * (-4) + 3 * (2*x) + 3 * (-4) = 2 * x² + (6 - 4) * x - 12 = 2 * x ² + 2 * x - 12

This is the polynomial we wanted to get:

p (x) = 2 * x² + 2 * x - 12

Answer:

0.5

Step-by-step explanation:

Hannah is in labor, she is 8 centimeters dilated. Shown in the diagram. Now, the perimeter of her puhtay and her child's head are 6/4. The fatctor of this is square b. Not a. To make Hannah's labor smooth, we need to figure out how much more she needs to dilate. since she is 8 centimeters, and the baby's head is 6/4. she will need 3 more centimeters until it is able to come out correctly. I hope this answered your question!! would love to answer more.

Answer:

x = 25

Step-by-step explanation:

Use Pythagoras' Theorem [tex]a^s+b^2=c^2[/tex]

where a and b are the legs and c is the hypotenuse of a right triangle

[tex]\implies 7^2+24^2=x^2[/tex]

[tex]\implies 49+576=x^2[/tex]

[tex]\implies 625=x^2[/tex]

[tex]\implies x=\sqrt{625}[/tex]

[tex]\implies x=\pm25[/tex]

[tex]\implies x = 25[/tex] only, as distance is positive

Use Pythagorean theorem

[tex]\\ \rm\longmapsto x^2=24^2+7^2[/tex]

[tex]\\ \rm\longmapsto x^2=576+49[/tex]

[tex]\\ \rm\longmapsto x^2=625[/tex]

[tex]\\ \rm\longmapsto x=25[/tex]

here,

area of a rectangle =70cm *

breadth = 7m

we know,

area (a)=l×b

70=l×7

70=7l

70÷7=l

10=l

therefore, itslength is 10m

again,

perimeter (p)=2(l+b)

=2(10+7)

=2×17

=34cm

therefore, its perimeter is 34cm.

The variance of a distribution is the square of the standard deviation

The variance of the data is 9

The given parameters are:

Mean = 9 cars

Distribution type = Poisson distribution

The variance and the mean of a Poisson distribution are equal.

So, we have:

Variance = 9 cars

Hence, the variance of the data is 9

Answer:

Because BC=AD=8, segment BC ≅ Segment AD. Because these are horizontal line segments, their slopes are 0 and they are parallel.

Segment BC and AD are opposite sides that are both congruent and parallel. So ABCD is a parallelogram by the opposite sides congruent theorem.

Step-by-step explanation:

So if you count the boxes of segment BC you will get 8, same for if you count the boxes that make up segment AD. If they are the same distance they are congruent. You can see how BC and AD are both horizontal lines. To find the slope you need to do the slope formula for BC and AD, which is y2-y1/x2-x1 in our case BC= 4-4/12-4 which equals 0/8. If you do the same formula for AD, you will get 0/8 making them congruent and the slope 0. If the opposite sides are congruent and parallel it has to be a parallelogram by the opposites and congruent theorem.

Answer:

y = - 4x + 15

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{x}{4}[/tex] - 2 ← is in slope- intercept form

with slope m = [tex]\frac{1}{4}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{4} }[/tex] = - 4 , then

y = - 4x + c ← is the partial equation

to find c, substitute (4, - 1 ) into the partial equation

- 1 = - 16 + c ⇒ c = - 1 + 16 = 15

y = - 4x + 15 ← equation of perpendicular line

y = - 4x + 15

y - 5 = -3(x + 3)

Step-by-step explanation:

A parallel line has the same slope but different y-intercept

So the slope of our line is -3

We also have our x1 and y1

So input that into the point-slope formula : y - y1 = m(x - x1)

The equation of the line is [tex]\boxed{\text{y - 5 = -3(x + 3)}}[/tex]

Answer:

Ratio of circumferences: [tex]\displaystyle\frac{1}{4}[/tex]

Ratio of radii: [tex]\displaystyle\frac{1}{4}[/tex]

Ratio of areas: [tex]\displaystyle\frac{1}{16}[/tex]

Step-by-step explanation:

Hi there!

We are given:

- The circumference of Circle K is [tex]\pi[/tex]

- The circumference of Circle L is [tex]4\pi[/tex]

Therefore, the ratio of their circumferences would be:

[tex]\displaystyle\frac{\pi}{4\pi}[/tex] ⇒ [tex]\displaystyle\frac{1}{4}[/tex] when simplified

The formula for circumference is [tex]C=2\pi r[/tex], where r is the radius. To find the ratio of the circles' radii, we must identify their radii through their given circumferences.

If the circumference of Circle K is [tex]\pi[/tex], or [tex]1\pi[/tex], then its radius is [tex]\displaystyle\frac{1}{2}[/tex].

If the circumference of Circle L is [tex]4\pi[/tex], then its radius is [tex]\displaystyle\frac{4}{2}[/tex], which is 2.

Therefore the ratio their radii would be:

[tex]\displaystyle\frac{\frac{1}{2}}{{2}}[/tex] ⇒ [tex]\displaystyle\frac{1}{2}*\frac{1}{2}[/tex] ⇒ [tex]\displaystyle\frac{1}{4}[/tex] when simplified

The formula for area is:

[tex]A=\pi r^2[/tex]

First, let's find the area of Circle K:

[tex]A=\pi (\displaystyle\frac{1}{2})^2\\\\A=\displaystyle\frac{1}{4}\pi[/tex]

Now, let's find the area of Circle L:

[tex]A=\pi (2)^2\\A = 4\pi[/tex]

Therefore, the ratio of their areas would be:

[tex]\displaystyle\frac{\frac{1}{4}\pi}{4\pi}[/tex] ⇒ [tex]\displaystyle\frac{\frac{1}{4}}{4}[/tex] ⇒ [tex]\displaystyle\frac{1}{4} * \frac{1}{4}[/tex] ⇒ [tex]\displaystyle\frac{1}{16}[/tex] when simplified

Answer:

x-intercept = 3/4

y-intercept = -3

Step-by-step explanation:

4x - y = 3 (Given)

To find x-intercept plug y = 0 in the given equation.

4x - 0 = 3

4x = 3

x = 3/4

To find y-intercept plug x = 0 in the given equation.

4(0) - y = 3

0 - y = 3

- y = 3

y = -3
