The equation of a line y=2x+8.

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in the value of y on the vertical axis/change in the value of x on the horizontal axis

Looking at the given line,

y = 2x + 7

Compared with the slope-intercept equation,

Slope, m = 2

If a line is parallel to another line, it means that both lines have equal or the same slope. This means that the slope of the line passing through the point (-2, 4) is 2

Substituting m= 2, y = 4 and x = -2 into the equation, y = mx + c , it becomes

4 = 2 × - 2 + c

4 = - 4 + c

c = 4 + 4 = 8

The equation becomes y=2x+8.

a) The limiting value of the temperature of the coffee is 25°C.

b) The limiting value of the rate of cooling is equals to 0.

c) The value of constant k in the

differential equation is -0.05.

d) The temperature of the coffee at time t = 10 is 66.33°C.

Newton's Law of Cooling: The rate at which an object's temperature changes is proportional to the difference in temperature between the object and its surroundings. For an object that has a temperature very close to that of its surroundings, the rate of heating or cooling becomes very small. We have the temperature of the coffee, T(t), satisfies the differential equation,

dT/dt= k(T − T (room)),

where T(room) = 25 is the room temperature, and k is some constant.

A) Limiting value of the temperature

= 25°C

B)limiting value of dT/dt = k[(limit temp) - (room temp)] = k(25 - 25)= 0

C) dT/dt = k(T - 25)

=> -2 = k (65 - 25)

=> -2 = 40k

=> k = -0.05

D) T' = -0.05 x (95-25) = - 3.5

h = 2, ∆T = -3.5x 2 = -7

T = 95- 7 = 88

Then T' = -0.05 x (88-25) = - 3.15

=> T = 88 - 2 x 3.15 = 81.7

=> 81.7 after 4 minutes

Then T' = -0.05x (81.7-25) = -2.835

T = 81.7 - 2x 2.835 = 76.03 after 6 mins

Then T' = -0.05 x (76.03-25) = -2.5515

T = 76.03 - 2 x 2.5515 = 70.92700 after 8 mins

Then T' = -0.05 x (70.927-25) = -2.29635

T = 70.927 - 2 x 2.29635

= 66.3343 after 10 minutes

It would take 17 years for the value of the account to reach $2,550. The solution has been obtained by using the concept of compound interest.

What is compound interest?

The principal as well as the interest that has accrued over the previous period are both used to compute interest. Compound interest factors the principal into the calculation for determining the interest for the subsequent month, in contrast to simple interest, which does not. In mathematics, the symbol for compound interest is typically the letter C.I.

We are given the principal amount as $790 paying an interest rate of 6.9% compounded continuously.

The final balance is $2,550.

We know that formula for continuous compounding interest is

[tex]P(t) = P_{0} e^{rt}[/tex]

So, using this, we get

⇒[tex]2550 = 790 e^{0.069*t}[/tex]

Answer:

Senior ticket = $10

Child's ticket = $8

Step-by-step explanation:

s = senior ticket

c = child's ticket

We need to write 2 equations, and we have 2 unknowns, s and c.

12s + 12c = 216

12() + 12c = 216

(70 - 5c) + 12c = 216

4 (70 - 5c) + 12c = 216

280 - 20c + 12c = 216

280 - 8c = 216  Add 8c to each side

280 - 8c + 8c = 216 + 8c

280 = 216 + 8c   Subtract 216 from each side.

280 - 216 = 216 - 216 + 8c

280 - 216 = 8c

64 = 8c   Divide each side by 8

64/8 = 8c/8

64/8 = c

8 = c

Now plug c into the first equation and solve for s.

3s + 5c = 70

3s + 5(8) = 70

3s + 40 = 70    Subtract 40 from each side.

3s + 40 - 40 = 70 - 40

3s = 70 - 40

3s = 30  Divide each side by 3

3s/3 = 30/3

s = 30/3

s = 10

So a senior ticket costs $10 and a child's ticket costs $8.

Answer: The total volume of concrete that Jimmy will need to create the 4 spheres is 38.25 cubic feet, rounded to the nearest whole number.

Step-by-step explanation:

To find the total volume of concrete needed for the 4 spheres, we need to find the volume of each sphere individually and then add them up. The formula for the volume of a sphere is (4/3)πr^3, where r is the radius of the sphere.

First, we need to find the radius of the largest sphere, which is 4 feet in diameter. The radius is half the diameter, so it is 2 feet.

The radius of the next sphere is half of the radius of the first sphere, which is 1 foot.

The radius of the next sphere is half of the radius of the second sphere, which is 0.5 feet.

The radius of the last sphere is half of the radius of the third sphere, which is 0.25 feet.

We can now use the formula to find the volume of each sphere and then add them up.

The volume of the first sphere = (4/3)π(2^3) = (4/3)π(8) = 33.49 cubic feet

The volume of the second sphere = (4/3)π(1^3) = (4/3)π(1) = 4.19 cubic feet

The volume of the third sphere = (4/3)π(0.5^3) = (4/3)π(0.125) = 0.52 cubic feet

The volume of the last sphere = (4/3)π(0.25^3) = (4/3)π(0.015625) = 0.05 cubic feet

Total volume of all spheres = 33.49 + 4.19 + 0.52 + 0.05 = 38.25 cubic feet

The total volume of concrete that Jimmy will need to create the 4 spheres is 38.25 cubic feet, rounded to the nearest whole number.

The missing side is 29, because in a triangle, the sum of the angles is 180°.  

A triangle is a three-sided polygon, a two-dimensional shape with three straight sides and three angles. It is one of the most basic shapes in geometry, and can be used to construct more complex shapes and figures such as rectangles and circles. Triangles come in many different varieties, including equilateral, isosceles, and scalene. The angles in a triangle add up to 180°, and the sides of a triangle are always connected.

In this case, 39° + X° = 180°, and X° = 180° - 39° = 141°. Since the angle is given in degrees, the side length can be found using the law of cosines, which states c^2 = a^2 + b^2 - 2ab cos C. In this case, c = 29, a = b = 11, and C = 141°. Plugging this into the equation, we get 29^2 = 11^2 + 11^2 - 2(11)(11)cos(141°). Simplifying and solving for c, we get c = 29. Therefore, the missing side is 29.

Answer:

  C. Exponential growth

Step-by-step explanation:

You want to know how to describe the relation that represents a 10% increase per year.

The problem statement tells you the number of guests "increased by approximately 10% each year". The nature of the function depends on what "10%" refers to.

If the amount of increase is constant year after year (10% of the original number of guests), then the relationship is linear.

If the amount of increase is 10% of the previous year's number, so the amount increases each year, then the relationship is exponential.

When the number increases year on year, the number is said to be growing. If the relationship is exponential, it is described as exponential growth.

If the number were decreasing by 10% per year, it would be an exponential decay relationship.

Additional comment

Whenever you're dealing with percentages, you always need to understand what is being used as the base amount. (What does 100% represent?)

Usually, a percentage increase or decrease is referring to the current value. Not always.

Sometimes a change from 10% to 6% is referred to as a 4% decrease, and sometimes it is referred to as a 40% decrease. It depends on who is selling what to whom.

The sample space for this experiment is the set of all possible outcomes of drawing 2 marbles from the box, where order matters. There are 3 choices for the first marble, and 3 choices for the second marble, so the sample space is {RR, RG, RB, GR, GG, GB, BR, BG, BB}. There are 9 possible outcomes in this sample space.

To determine the sample space for this experiment, we first list all the possible outcomes for the first marble that we could draw. There are 3 marbles in the box (red, green, and blue), so there are 3 choices for the first marble. We can represent these choices as R, G, and B.

Next, we list all the possible outcomes for the second marble that we could draw. Since the box is being replaced with the first marble before the second draw, there are still 3 marbles in the box (red, green, and blue), so there are still 3 choices for the second marble. We can represent these choices as R, G, and B.

Finally, we list all possible combinations of the first and second marble, which forms the sample space. Since order matters, we list all the possible combinations of R, G, and B as pairs. In this case, there are 3 choices for the first marble and 3 choices for the second marble, which gives us 3 * 3 = 9 possible outcomes in the sample space: {RR, RG, RB, GR, GG, GB, BR, BG, BB}.

To find the distance traveled by a car given the average speed and time traveled, we can use the formula:

distance = speed x time

In this case, the average speed of the car is 48 miles per hour (mph) and the time traveled is 5 hours and 45 minutes.

Before we use this formula, we need to convert the time of 5 hours and 45 minutes into hours. Since there are 60 minutes in 1 hour, we can convert 45 minutes into hours by dividing it by 60:

45 minutes / 60 minutes/hour = 0.75 hours

Now, we can add the time in hours and minutes to get the total time traveled in hours:

5 hours + 0.75 hours = 5.75 hours

Now we can use the formula to find the distance traveled:

distance = speed x time

distance = 48 mph x 5.75 hours

distance = 277 miles

So, the car travels 277 miles in 5 hours and 45 minutes.

Answer: 275 Miles

Step-by-step explanation:

1. Convert the hours into minutes:
We'll take the 5 hours and 45 minutes and divide the minutes by 60, giving you 5.75 hours.

2. Multiply the hours by the rate

The rule for dilation around the origin with a scale factor of k is (x,y) -> (kx,ky).

Dilation is a transformation in geometry that changes the size of a figure while preserving its shape. A dilation centered at the origin involves scaling the figure down by a factor, causing it to become smaller.

In this case, the origin acts as the center of dilation, with the original figure being mapped to a smaller, similar figure.

To perform a dilation, each point of the original figure is multiplied by the same scale factor, resulting in a smaller, proportional figure.

The scale factor determines how much the figure will be reduced. It is important to note that dilations centered at the origin preserve the orientation of the figure, meaning it will look the same as the original, but just smaller.

The eigenvalue λ is equal to -tan(θ)(4cos(4θ)) / sin(4θ). The exact value of the eigenvalue depends on the specific value of θ, as both tan(θ) and cos(4θ) vary with θ.

To find the eigenvalue, we need to multiply the operator by the eigenfunction and see what we get:

(-tan(θ)d/dθ)(sin(4θ)) = -tan(θ)(d/dθ)(sin(4θ)) = -tan(θ)(4cos(4θ))

Since sin(4θ) is an eigenfunction, we expect that the result of the operator multiplied by the eigenfunction should be proportional to the eigenfunction. In other words, there should be a scalar factor multiplying the eigenfunction. This scalar factor is the eigenvalue.

So, we can write:

(-tan(θ)d/dθ)(sin(4θ)) = λsin(4θ)

where λ is the eigenvalue. Equating the right-hand sides of the two equations, we find:

-tan(θ)(4cos(4θ)) = λsin(4θ)

Dividing both sides by sin(4θ), we get:

-tan(θ)(4cos(4θ)) / sin(4θ) = λ

So, the eigenvalue λ is equal to -tan(θ)(4cos(4θ)) / sin(4θ). The exact value of the eigenvalue depends on the specific value of θ, as both tan(θ) and cos(4θ) vary with θ.
