Answer:

f (x) = { 19 + 0.39(x - 300), x > 300

Step-by-step explanation:

Andrew has a cell phone plan that provides 300 free minutes each month for a flat rate of $19. For any minutes over 300, Andrew is charged $0.39 per minute. Let x be the number of minutes Andrew uses per month and f(x) be the charges based on Andrew's cell phone plan. If  then If  then first 300 minutes are free and each minute of next (x-300) minutes costs $0.39, therefore Hence, { 19 + 0.39(x - 300), x > 300

Given:

Consider the below figure attached with this question.

In circle A below, chord BC and diameter DAE intersect at F.

The arc CD = 46° and arc BE = 78°.

To find:

The measure of angle BFE.

Solution:

According to intersecting chords theorem, if two chords intersect inside the circle then the angle on the intersection is the average of intercepted arcs.

Using intersecting chords theorem, we get

\(m\angle BFE=\dfrac{1}{2}(m(arcCD)+m(arcBE))\)

\(m\angle BFE=\dfrac{1}{2}(46^\circ+78^\circ)\)

\(m\angle BFE=\dfrac{1}{2}(124^\circ)\)

\(m\angle BFE=62^\circ\)

Therefore, the measure of angle BFE is 62°.

This result tells us that the points P, T and R are collinear and that the lengths of the line segments PQ, PS and SR are all related to each other.

This result tells us that the points P, T and R are collinear. This can be seen from the fact that the ratio of the length of the line segment PT to the length of the line segment PR is a fraction (k). This implies that the points P, T and R lie on the same line. Furthermore, this result also tells us that the lengths of the line segments PQ, PS and SR are all related to each other. Specifically, we can see that the length of the line segment PS is equal to the sum of the lengths of the line segments PQ and SR. We can also see that the length of the line segment PT is equal to one fourth of the length of the line segment PQ. This result is useful in helping us to understand the relationships between the points in a trapezium and how they are related to one another.

The expression which shows how many grams of raisins are in the bowl will be

(0.01x) * 150 + (0.01y) * 250

An expression is simply used to show the relationship between the variables that are provided or the data given regarding an information. In this case, it is vital to note that they have at least two terms which have to be related by through an operator. Some of the mathematical operations that are illustrated in this case include addition, subtraction, etc.

The expression which shows how many grams of raisins are in the bowl will be:

= (x% × 150) + (y% × 250)

= (0.01x) * 150 + (0.01y) * 250

This equation represents the total grams of raisins in the bowl by multiplying the weight of the Oreana's bag by the percentage of raisins in it, and adding that to the product of the weight of Brandon's bag and the percentage of raisins in it. The "0.01" is used to convert the percentages from x and y to decimal form.

To simplify the expression, we will expand the parenthesis:

The length of v to the nearest 10th of an inch is 2.0 inches.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

We can use the Law of Sines,

Which states that for any triangle ABC:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides of the triangle opposite the angles A, B, and C.

Now,

a = UV = u = 3.4 inches

A = ∠TUV

  = 180° - m∠U - m∠V

  = 180° - 144° - 35°

  = 1°

B = ∠UTV

   = m∠U

   = 144°

C = ∠TVU

  = m∠V

  = 35°

Using the Law of Sines,

v/sin(C) = u/sin(B)

Substituting in the values.

v/sin(35°) = 3.4/sin(144°)

Solving for v.

v = (3.4 × sin(35°)) / sin(144°)

v = 1.97 inches

Therefore,

The length of v to the nearest 10th of an inch is 2.0 inches.

Answer:

Step-by-step explanation:

To find the time at which the rocket will splash down, we need to set h(t) to 0 and solve for t:

h(t) = -4.9t^2 + 169t + 234 = 0

Using the quadratic formula, we get:

t = (-b ± sqrt(b^2 - 4ac)) / 2a

Where a = -4.9, b = 169, and c = 234.

Plugging in the values, we get:

t = (-169 ± sqrt(169^2 - 4(-4.9)(234))) / 2(-4.9)

t = (-169 ± sqrt(28561.6)) / (-9.8)

We only want the positive value of t, as the rocket is launched at t = 0 seconds, so:

t = (-169 + sqrt(28561.6)) / (-9.8) = 17.2832 seconds (rounded to 4 decimal places)

Therefore, the rocket will splash down after 17.2832 seconds.

To find the height of the rocket at its peak, we need to find the vertex of the parabolic function h(t), which occurs at the value of t given by:

t = -b / 2a = -169 / 2(-4.9) = 17.3469 seconds (rounded to 4 decimal places)

At the time t = 17.3469 seconds, the height of the rocket is given by:

h(17.3469) = -4.9(17.3469)^2 + 169(17.3469) + 234 = 1764.203 meters (rounded to 3 decimal places)

Therefore, the rocket peaks at a height of 1764.203 meters above sea-level.

By using the concept of intercept the method of estimation of intercepts has been described below

What are intercepts?

The distance from the origin to the point where the graph cuts the x axis is the x - intercept of the graph

The distance from the origin to the point where the graph cuts the y axis is the y -  intercept of the graph

There are two intercepts of a graph, x - intercept and y - intercept

x-axis is the horizontal axis and y axis is the vertical axis of the graph

Let the function be y = f(x)

To find x intercept, we have to substitute y = 0 and solve for x

The value of x will give the x intercept

To find y intercept, we have to substitute x = 0 and solve for y

The value of y will give the y intercept.

1.  The new volume will be 60 cubic feet. 2. Molly will earn $31.25 if she sells all of the dog beds after subtracting the cost of the fabric.

In general, volume refers to the amount of space occupied by an object or substance, measured in three dimensions: length, width, and height. It is a physical quantity that is typically expressed in cubic units, such as cubic meters (m³), cubic centimeters (cm³), or cubic feet (ft³).

1. The volume of the cuboid is calculated as follows:

Volume = length x width x height

Volume = 5 ft x 3 ft x 2 ft

Volume = 30 cubic feet

If we double the height, the new height will be 2 x 2 ft = 4 ft. The new volume can be calculated as:

New Volume = length x width x new height

New Volume = 5 ft x 3 ft x 4 ft

New Volume = 60 cubic feet

Therefore, the new volume will be 60 cubic feet.

2. Step 1: Determine how many dog beds Molly can make with the fabric she bought.

Molly bought 12.5 yards of fabric, and she uses 2.5 yards of fabric for each dog bed. We can use division to find how many dog beds she can make:

12.5 yards / 2.5 yards per dog bed = 5 dog beds

Therefore, Molly can make 5 dog beds with the fabric she bought.

Step 2: Calculate the cost of the fabric for each dog bed.

Molly bought the fabric for $4.50 per yard, and she uses 2.5 yards of fabric for each dog bed. Therefore, the cost of the fabric for each dog bed is:

$4.50 per yard x 2.5 yards per dog bed = $11.25 per dog bed

Step 3: Calculate the revenue from selling one dog bed.

Molly sells each dog bed for $17.50.

Step 4: Calculate the profit from selling one dog bed.

Profit = revenue - cost

Profit = $17.50 - $11.25

Profit = $6.25

Step 5: Calculate the total revenue from selling all of the dog beds.

Molly can make 5 dog beds, and each dog bed sells for $17.50. Therefore, the total revenue is:

5 dog beds x $17.50 per dog bed = $87.50

Step 6: Calculate the total cost of the fabric for all of the dog beds.

Molly uses 2.5 yards of fabric for each dog bed, and she can make 5 dog beds. Therefore, the total cost of the fabric is:

2.5 yards per dog bed x 5 dog beds = 12.5 yards

$4.50 per yard x 12.5 yards = $56.25

Step 7: Calculate the total profit from selling all of the dog beds.

Profit = revenue - cost

Profit = $87.50 - $56.25

Profit = $31.25

Therefore, Molly will earn $31.25 if she sells all of the dog beds after subtracting the cost of the fabric.

The probability of randomly picking a school or library-related issue from the ballot is 9/19 or approximately 0.474 (rounded to three decimal places).

To determine the probability of a randomly picked issue being school or library related, you'll need to consider the total number of issues and the number of school and library issues combined.

There are 7 school-related issues, 10 ordinance-related issues, and 2 library-related issues, making a total of 19 issues on the ballot. To find the probability of picking a school or library issue, combine the number of school and library issues: 7 + 2 = 9.

Now, divide the number of school and library issues (9) by the total number of issues (19): 9/19.
