Answer: The answer is A.

Step-by-step explanation: You cant go over the $15 limit and in answer A, the sign shows that 1.80x + 1.95y is less than or equal to 15.

the answer to this question is A

Parallel lines have the same slopes (but different y intercepts). Parallel lines never cross. Parallel lines are the same distance from each other no matter where you are on either line. Think of it like a pair of perfectly straight railroad tracks.

-------------------------------------------------------------------------------------

Perpendicular lines cross at one point. The two lines form a 90 degree angle. The two slopes multiply to -1, which is another way of saying that the slopes are negative reciprocals of one another. For example, a line with a slope of 2/3 and another line with a slope of -3/2 has these two values multiply to -1; therefore showing they are perpendicular lines.

To provide a short definition,

Parallel lines are lines as the word suggests "parallel" which means they will stay side by side and never cross.

Perpendicular lines are lines that cross, usually to determine perpendicular lines you would take a slope and negatively reciprocate it.

Perpendicular:

1/2 -> -2

Parallel:

Answer: w = 7cm

Step-by-step explanation:

Perimeter = 2 x length + 2 x width  = 2L  + 2w

 Width is 4 cm less than the length, so w = L-4

  36 = 2L + 2(L-4)

 36 = 2L + 2L - 8

 36 = 4L - 8

44 = 4L

 L = 11

w = 7

2(11) + 2(7) = 22 + 14 = 36

Length is 11, width is 7

Answer:

Answer:

C. 20 seconds

Step-by-step explanation:

We want to know when y=0.

We are finding the x intercepts.

The first y is when it started and the second y=0 is when it stops.

Looking at the graph y=0 at x=0 and  y=0 at x=20

The fan started at time 0 and stopped at 20 seconds.

The difference is the length of the test.

20-0 = 20

20 seconds

Answer:

20 seconds

Step-by-step explanation:

Given :

[tex]y=-5x^2+100x[/tex]

Where x  represents time in seconds and y represents the speed in rotations per minute.

To Find : Assuming that the test was complete when the fan stopped spinning completely, how long was the test?

Solution:

Since we are supposed to find how long will it take to stop the fan completely

We assumed that  test was complete when the fan stopped spinning completely

i.e. y = Speed = 0

So, Substitute y = 0 in the equation    [tex]y=-5x^2+100x[/tex]

⇒[tex]0=-5x^2+100x[/tex]

⇒[tex]5x^2=100x[/tex]

⇒[tex]5x=100[/tex]

⇒[tex]x=\frac{100}{5}[/tex]

⇒[tex]x=20[/tex]

Thus it took 20 seconds to stop the fan

Hence the test was 20 seconds long.

Answer:

z=4  and z=-1/3  are the zero's

Step-by-step explanation:

To find the zeros of the quadratic function, we need to set it equal to zero.

f(z)=3z^2−11z−4

0 =3z^2−11z−4

Now we need to factor the function

0 = (z - 4) (3 z + 1)

Then using the zero product property set each factor to zero

0 = z-4   0 = 3z+1

Now solve

0+4 = z-4+4          0 -1 = 3z+1-1

4 =z                         -1 = 3z

                                -1/3 = 3z/3

                                   -1/3 =z

Step-by-step explanation:

Answer:

d. -5/8

Step-by-step explanation:

To find slope, use the following equation

slope (m) = (y₂ - y₁)/(x₂ - x₁)

First, set each coordinate. Let:

(x₁ , y₁) = (-6 , 8)

(x₂ , y₂) = (2 , 3)

Plug in the corresponding numbers for the corresponding variables.

m = (y₂ - y₁)/(x₂ - x₁)

m = (3 - 8)/(2 - (-6))

Simplify. Note that two negative signs would result in a positive sign.

m = (3 - 8)/(2 + 6)

m = -5/8

d. -5/8 is your answer

Answer:

The required ratio is: 9:5

Step-by-step explanation:

Let the number of frog's Rimma has be x

Then Julia's will be [tex]\frac{2x}{5}[/tex]

Now, Rimma give 1/2 of her frog to Julia means now, Rimma will have [tex]x-\frac{1}{2}[/tex] frog

Then Julia's frog will be [tex]\frac{2x}{5}+\frac{1}{2}[/tex]

Now, Rimma will have [tex]x-\frac{x}{2}=\frac{x}{2}[/tex]

And Julia will have [tex]\frac{2x}{5}+\frac{x}{2}=\frac{4x+5}{10}=\frac{9x}{10}[/tex]

Hence, the ratio of Julia's frog to Rimma's frog is [tex]\frac{\frac{9x}{10}}{\frac{x}{2}}[/tex]

[tex]Ratio=\frac{9x\cdot 2}{10\cdot x}[/tex]

[tex]\Rightarrow Ratio=\frac{9}{5}[/tex]

The required ratio is: 9:5

=>taking L.C.M of the denominator

=>11/36 - 7/36

=>4/36

=>2/18=>1/9

Answer:

it is 5 36

heres why

Step-by-step explanation:

Here's how to subtract 7/9 from 11/12:

11

12

−  

7

9

Step 1

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 11 by 9, and get 99.

Then we multiply 7 by 12, and get 84.

Next we give both terms new denominators -- 12 × 9 = 108.

So now our fractions look like this:

99

108

−  

84

108

Step 2

Since our denominators match, we can subtract the numerators.

99 − 84 = 15

So the answer is:

15

108

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Nope! So now we try the next greatest prime number, 3...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:

15

108

÷ 3 =  

5

36

Let's try dividing by 3 again...

Nope! So now we try the next greatest prime number, 5...

Nope! So now we try the next greatest prime number, 7...

No good. 7 is larger than 5. So we're done reducing.

There you have it! The final answer is:

11

Step 3.

Calculate the circumference of the Earth (circle):

[tex]C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi[/tex]

Step 4.

The length of arc is equal 1/40 of the circumference:

[tex]\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi[/tex]

[tex]\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi[/tex]

The question uses geometry and the concept of arc length to ask the distance between Seattle and San Francisco on the Earth's surface. The distance between the two cities is calculated to be 628 miles.

This is a mathematics problem using geometry, specifically related to the calculation of the arc length. The difference in latitudes between Seattle and San Francisco gives us the angle measurement on the sphere's surface. The difference is 47° - 38° = 9°. Since 9° is 1/40th of a full circle (360°), the arc is 1/40th of the total circumference.

So, to find the distance between the two cities, we calculate 1/40th of the circumference of the Earth (which is 2πr) by using the given radius of the Earth (4,000 miles). The calculation is 1/40 * 2 * 3.14 * 4000 = 628 miles. So, The distance between Seattle and San Francisco via the arc length on the sphere's surface is approximately 628 miles.

Therefore, the correct answer is A) 628 miles.

Answer: p = $100,  R = $25,000

Step-by-step explanation:

The maximum is the y-value of the Vertex.

Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x: [tex]x=\dfrac{-b}{2a}[/tex]

R(p) = -2.5p² + 500p

        a=-2.5  b=500

[tex]p=\dfrac{-(500)}{2(-2.5)}[/tex]

   [tex]=\dfrac{-500}{-5}[/tex]

   [tex]=100[/tex]

Step 2: Find the maximum by plugging the p-value (above) into the given equation.

R(100) = -2.5(100)² + 500(100)

          = -25,000 + 50,000

          = 25,000

The price that maximizes revenue for the software package is $100, and the maximum revenue attainable is $25,000 based on the given revenue function R(p).

To find the price that maximizes revenue and the maximum revenue itself, we can use the given revenue function R(p) = -2.5p² + 500p.

To find the price that maximizes revenue, we need to find the vertex of the quadratic function, as the vertex represents the maximum point. The formula for the x-coordinate (price in this case) of the vertex of a quadratic function in the form of ax² + bx + c is given by:

x_vertex = -b / (2a)

In our case, a = -2.5 and b = 500:

x_vertex = -500 / (2 * (-2.5))

x_vertex = -500 / (-5)

x_vertex = 100

So, the price that maximizes revenue is $100.

To find the maximum revenue, we need to substitute this price back into the revenue function:

R(100) = -2.5(100)² + 500(100)

R(100) = -2.5 * 10000 + 50000

R(100) = -25000 + 50000

R(100) = 25000

Therefore, the maximum revenue is $25,000.

So, the price that maximizes revenue is $100, and the maximum revenue is $25,000.
