How to solve for y=mx on a graph

The number of miles driven if the cost of renting a car is $130 with a cost function of c(m) = 0.05m + 30 is 2000 miles.

We can start by setting up an equation to solve for the number of miles driven, m

c(m) = 0.05m + 30 (where c(m) is the cost of renting a car)

We know that the cost is $130, so we can substitute that into the equation

130 = 0.05m + 30

Now we can solve for m

130 - 30 = 0.05m

Subtract the numbers

100 = 0.05m

m = 100/0.05

Divide the numbers

m = 2000 miles

Therefore, the number of miles driven is 2000 miles

We are given that Jeremiah signed up for a streaming music service that costs $7 per month.

Cost per month = $7

Cost of Offline download = $0.50 per song

Total amount Jeremiah will pay = $7 + $1.25(50)

= 7 + 62.5

= $69.5

Jeremiah will have to pay $69.5 in a month in which he downloaded 50 songs.

Therefore, Total amount Jeremiah will pay for s songs = $7 + $1.25* s

t = 18, -18

To solve, we will isolate the variable t.

Given:

      0.5t² = 162

Divide both sides of the equation by 0.5:

      t² = 324

Square root both sides of the equation:

      t = 18, -18

The required solution to the equation [tex]0.5t^2 = 162[/tex] is t = ±18, as of the given condition.

To solve the equation [tex]0.5t^2 = 162[/tex], we need to isolate the variable t.

First, we can start by dividing both sides of the equation by 0.5 to eliminate it on the left side:

[tex]0.5t^2 / 0.5 = 162 / 0.5[/tex]

Simplifying:

[tex]t^2 = 324[/tex]

Next, we take the square root of both sides to solve for t:
[tex]\sqrt(t^2) = \sqrt(324)[/tex]

t = ±18

Therefore, the solution to the equation [tex]0.5t^2 = 162[/tex] is t = ±18.

The volume of the triangular prism whose base = 4.8m , height = 3.2m, length = 9m is 69.12 cubic meters.

To find the volume of a triangular prism, we need to multiply the area of the base by the height and the length of the prism. The formula for the volume of a triangular prism is:

V = 1/2 x b x h x l

where b is the length of the base, h is the height of the base, and l is the length of the prism.

In this case, the base of the triangular prism has a length of 4.8m and a height of 3.2m, so the area of the base is:

A = 1/2 x b x h = 1/2 x 4.8m x 3.2m = 7.68m²

The length of the prism is 9m, as given in the problem.

The speed of the car traveling is 42.96km/hr, under the condition  if d=0. 05v²+2. 2v.

The distance a car travels is 200. We can perform the formula d = 0.05v² + 2.2v to evaluate the speed of the car.
Staging d = 200 in the above equation, we get:

0.05v² + 2.2v - 200 = 0

Evaluating this quadratic equation gives us two values of v:

v = (-2.2 ± √(2.2² + 4 × 0.05 × 200)) / (2 × 0.05)

v ≈ -44.96 or

Step-by-step explanation:

To find the area of the garden covered by the pond, we need to find the area of sector ACB.

First, we need to find the measure of the central angle of sector ACB. The central angle is the same as the angle formed by radii OA and OB.

Since the radius of the garden is 3 meters, we can use the Pythagorean theorem to find the length of the chord AB:

AB² = OA² + OB²

AB² = 3² + 3²

AB² = 18

AB = √18 ≈ 4.24 meters

Now, we can use the formula for the area of a sector:

A = (θ/360)πr²

where θ is the central angle and r is the radius of the circle.

The central angle of sector ACB can be found using the inverse cosine function:

cos(θ/2) = AB/2r

cos(θ/2) = 4.24/(2*3)

cos(θ/2) ≈ 0.707

θ/2 ≈ cos⁻¹(0.707)

θ ≈ 2cos⁻¹(0.707)

θ ≈ 144.1 degrees

Now we can calculate the area of sector ACB:

A = (θ/360)πr²

A = (144.1/360)π(3)²

A ≈ 10.6 square meters

Therefore, the area of the garden covered by the pond is approximately 10.6 square meters.

The approximation of g(-1.2) using the line tangent to the graph of g at x=-1 is 3.6.

We can use the formula for the equation of a tangent line to approximate the value of g(-1.2) using the given information:

y - y1 = m(x - x1)

m = g'(-1) = 2 (since g'(-1) = 2)

Substituting these values into the formula, we get:

y - 4 = 2(x + 1)

Simplifying:

y = 2x + 6

Now we can use this equation to approximate g(-1.2) by plugging in x=-1.2:

g(-1.2) ≈ 2(-1.2) + 6

g(-1.2) ≈ 3.6

Two possible values for the meteorologist's prediction are  $35.24$ inches and $50.76$ inches.

Let's denote the meteorologist's rainfall prediction by x.

The percent error can be calculated using the formula:

We can use this formula to set up an equation and solve for x.

Since we want to find two possible values for x, we can use both the positive and negative versions of the percent error:

18.02% = |(43 - x) / 43| x 100% or

-18.02% = |(43 - x) / 43| x 100%

We have to find the values of x

18.02% = |(43 - x) / 43| x 100%

0.1802 = |(43 - x) / 43|

0.1802 x 43 = |43 - x|

7.7566 = |43 - x|

In the year 2040, the populations of the two towns will be approximately equal.

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13. 2x - 5 and 13 are expressions in this case. These two expressions are joined together by the sign "=".

To find the year when the populations of the towns will be approximately equal, we need to set the two equations equal to each other and solve for t:

8t² + 2000 = 100t + 3000

8t² - 100t - 1000 = 0

We can simplify this equation by dividing both sides by 4:

2t² - 25t - 250 = 0

Now we can solve for t using the quadratic formula:

t = (-b ± √(b² - 4ac)) / 2a

where a = 2, b = -25, and c = -250. Plugging in these values, we get:

t = (25 ± √(25² - 4(2)(-250))) / (2(2))

t = (25 ± √(9375)) / 4

t = (25 ± 97.0) / 4

So t = 30.25 or t = -6.25. We can ignore the negative solution since we're looking for a year after 2010. Therefore, the populations of the two towns will be approximately equal in the year:

2010 + 30.25 = 2040.25

So, in the year 2040, the populations of the two towns will be approximately equal.
