A computer company uses the linear model y = -21x + 13,082 to predict the decline in sales of a computer after it has been on the market more than one year. If x is the number of months after the first year and y is the number of computers sold during that month, how many computers will be sold 11 months after the first year?

Answers

Answer 1

you have to plug in 11 for x since x is the number of months so when you plug it in you would rewrite the equation as y=-21(11)+13082. Then you would solve for y. -21 x 11 is -231. -231 + 13082 = 12851 computers sold in 11 months after the first year. :) hope this helps

Rewrite the following equation in slope-intercept form. 17x + 4y = -14 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:
y = [tex] \frac{-17}{4} x[/tex] - [tex] \frac{7}{2} [/tex]

Explanation:
The slope-intercept form of an equation has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
17x + 4y = -14

To put this in slope-intercept form,we will need to isolate the y as follows:
17x + 4y = -14
4y = -17x - 14
y = (-17/4)x - (14/4)
y = [tex] \frac{-17}{4} x[/tex] - [tex] \frac{7}{2} [/tex]
where:
m is the slope = -17/4
c is the y-intercept = -7/2

Hope this helps :)

17x+4y = -14
Y= 0
17x = -14
X=-14/17

X=0
4y= -14
Y= -14/4

how long will it take for the pool to completely fill with water? (explain why so i understand) it’s a 120 gallon pool

Answers

First, you find out how much can be filled in 1 minute. Then you divide that into 120 to get your answer.

To find out how much can be filled in 1 minute, take the time and divide it into the volume. We'll use the second row (2 minutes and 8 gallons.)

8/2=4. So it takes 1 minute to fill 4 gallons. Now, you just divide 4 into 120.

120/4=30

It takes 30 minutes to fill the pool up to 120 gallons.

It would take 30 min to fill up the pool

How far is it from the log ride to the pirate ship?

Answers

If I am correct it would be 37.5 meters.

Final answer:

The question seems to ask for the distance between two amusement park rides but actually gives details about the pendulum motion of a pirate ship ride. Without specific distance data or a park map, the physical distance cannot be determined from the given information. Physics concepts like kinetic energy can be discussed, but they don't provide the actual distance.

Explanation:

The question relates to the concept of pendulum motion within the field of physics. The student is seemingly referring to the distance between two rides in an amusement park: a log ride and a ride that is shaped like a pirate ship, which operates similarly to a pendulum. Since the question does not provide specific distances between the two rides, the answer would typically involve measuring the distance directly on-site or consulting a park map. However, the information given does describe the motion of the pirate ship ride. The ride is akin to a rigid pendulum, and it reaches a speed of 23.4 m/s at the bottom of its circular arc. This information can be used to discuss the kinetic energy and potential energy exchanges during the ride, but not the physical distance between the rides. To measure the distance in the park, one would likely need additional information about the park layout or GPS measurements.

Hello there! I can help you! The formula for compound interest is P(1 + r)^t, where P= principal (initial amount), r = interest rate (in decimal form), and t = time (in years). Let's do this step by step. First off, we add the rate into 1. 4% is the interest rate (0.04 in decimal form). 1 + 0.04 is 1.04. Now, what we will do is raise that number to the 2nd power, because the time that elapses is 2 years. 1.04² is 1.0816. That's that. Now, multiply 7,500 to find the total amount of money. 1.0816 * 7,500 is 8,112. There. Toby's savings account balance in 2 years is £8,112.

Note: To solve for compound interest questions like it, add 1 to the percentage rate in decimal form, raise that number to a power based on the number of years (for example, raise the number to the 7th power if we are looking for the balance after 7 years), and then multiply that number by the starting amount. After you raise the number by a power, there may be a lot of numbers behind it. Whatever you do, DO NOT delete the number. Keep it there and multiply it by the principal.

Area of wall = [tex] 94 \frac{47}{48} [/tex] ft

Therefore, the dimensions of the wall would be as follows:
H = 7 ft 10 in = [tex] 7 \frac{10}{12} [/tex] ft
B1 = 10 ft 2 in = [tex]10 \frac{2}{12} [/tex] ft
B2 = 14 ft 1 in = [tex]14 \frac{1}{12} [/tex] ft

For the trapezium, area can be calculated using the following the following formula:
Area of trapezium = Average base * height = [tex] \frac{B1 + B2}{2} [/tex] * height

Substitute with the given to get the area as follows:

barry has an ice tray that makes ice cubes shaped like a cone with a diameter of 2 cm and height of 2 cm to the nearest cubic centimeter what is the volume of an ice cube from barry's tray 2cm2 8cm3 25 cm3 101 cm2

Answers

we know that
the volume of a cone=(1/3)*pi*r²*h
where
r is the radius
h is the height

in this problem
diameter=2 cm
so
r=diameter/2-----> r=2/2-----> r=1 cm
h=2 cm
volume of a cone=(1/3)*pi*1²*2------> 2.09 cm³------> 2 cm³

the answer is
2 cm³

Answer
2 cm²

Explanation
The volume of a cone is found by the formula;
Volume =1/3 πr² h
Where π=3.142
r=2/2=1 cm
h=2 cm
Volume = 1/3×3.142×1²×2
2.09466667
To the nearest whole number the answer is 2 cm².

Sarah needs to buy 3 identical shirts to wear. She had $15 gift certificate. Including using the gift certificate, she can spend no more than $80. Which inequality can be used to determine the possible costs for a shirt ?

Answers

Let the cost of a shirt be s.

Three shirts = 3s.

3s + 15 ≤ 80 (Answer F)

Final answer:

The inequality that can be used to determine the possible costs for a shirt is 3x ≤ 65, where x represents the cost of each shirt. Therefore, the possible costs for a shirt must be less than or equal to $21.67.

Explanation:

To determine the possible costs for a shirt, we can use the inequality 3x ≤ 80 - 15,

where x represents the cost of each shirt. The left side of the inequality, 3x, represents the total cost of the 3 shirts. The right side of the inequality, 80 - 15,

represents the amount Sarah has left to spend after using the gift certificate.

Simplifying the inequality, we get 3x ≤ 65.

To find the maximum cost for each shirt, we divide both sides of the inequality by 3, giving us x ≤ 21.67.

Therefore, the possible costs for a shirt must be less than or equal to $21.67.

Answer:

[tex]\Delta t=9\: hours[/tex]

Step-by-step explanation:

1) If Tameron is driving 540 miles at a rate of 45 mph, then he may take 12 hours to make that trip. We'll use the formula below, that relates the rate for average speed is equal to the variation of space over the variation of time.

[tex]V_{m}=\frac{\Delta s}{\Delta t}\Rightarrow 45=\frac{540}{\Delta t}\Rightarrow \Delta t=\frac{540}{45}\Rightarrow 45\Delta t=540\:\Rightarrow \Delta t=\frac{540}{45}\Rightarrow \Delta t=12[/tex]

2) Although if he's already done 1/4 of the way , i.e. 135 miles then he's left with [tex]\frac{3}{4}[/tex]of the track to go.

Assuming He'll keep the speed rate,

[tex]\Delta t=\frac{540*\frac{3}{4}}{45}\Rightarrow \Delta t=9\: hours[/tex]
