Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle equals 180 degrees, therefore,

180 = m<1 + m<2 + m<3

180 - m<3 = m<1 + m<2

But, we also know that m<4 + m<3 = 180 degrees.

180 = m<3 + m<4

180 - m<3 = m<4

Both m<4 and m<1 + m<2  equals 180 - m<3

m<4 = m<1 + m<2

Step-by-step explanation:

Steve and Stephanie need to complete 4 hours of housework for their allowances to be equal.

"It is a mathematical statement which consists of equal symbol between two algebraic expressions."

For given question,

Let 'x' represents the Steve's weekly allowances and 'y' represents the Stephanie's weekly allowance.

Let h represent the number of hours.

Steve receives $15 plus $1.25 for every hour he completes housework.

So, we get an equation,

⇒ x = (1.25)h + 15

Stephanie receives $5 for every hour she completes housework.

So, we get an equation,

⇒ y = 5h

We need to find the number of hours of housework they need to complete for their allowances to be equal.

When  their allowances are equal,

⇒ x = y

⇒ (1.25)h + 15 = 5h

⇒ 3.75 h = 15

⇒ h = 4 hours

Therefore, they need to complete 4 hours of housework for their allowances to be equal.

These lines will be parallel to the initial line and will intersect the final velocity line at the corresponding values (122 for the lower estimate and 298 for the upper estimate)

To sketch the velocity against time, you can take the following steps:

First, calculate the acceleration using the given data by using the formula;

acceleration = (final velocity - initial velocity)/time

Where; Initial velocity is the velocity before applying the brakes

Final velocity is the velocity at which the car comes to stop

Time is the time it takes to stop the car (6 seconds in this case)

Now, calculate the lower and upper estimates using the formula;

Lower estimate = initial velocity + (acceleration x time)

Upper estimate = initial velocity + (2 x acceleration x time)

Sketch the graph using the following steps;

On the vertical axis, plot the velocity of the car

On the horizontal axis, plot the time

Start from the initial velocity and draw a straight line with the calculated acceleration until the end of the time (6 seconds)This straight line will give you the final velocity (0 in this case)

Now, draw two more lines, one with the lower estimate and the other with the upper estimate

Finally, label the axes and the lines with their corresponding values.'

The graph has an asymptote at y = 0.

Option (A) is correct.

What is the asymptote of the graph?

An asymptote is a straight line that constantly approaches a given curve but does not meet at an infinite distance. In other words, an Asymptote is a line that a curve approaches as it moves toward infinity.

The given function is:

                                \(y = 12.(\frac{1}{2})^x\)

Now let's draw the graph for this given function,

By observing the graph we can conclude that the graph has an asymptote at y = 0 cause it is not meeting to the x-axis when it is approaching infinity.

Answer:

x = 11, ∠ B = 71°

Step-by-step explanation:

In a parallelogram, consecutive angles are supplementary, that is

∠ A + ∠ B = 180°, thus

8x + 21 + 5x + 16 = 180

13x + 37 = 180 ( subtract 37 from both sides )

13x = 143 ( divide both sides by 13 )

x = 11

Thus

∠ B = 5x + 16 = 5(11) + 16 = 55 + 16 = 71°

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

Let's examine the given triangle. Angle x is an exterior angle. <BAC is an interior angle of the triangle. <x and <BAC are adjacent angles. Angles B and C are not adjacent to <x. "Remote" means far away. Of all interior angles of triangle ABC, angles B and C are the remote interior angles of exterior angle x.

Now look at the theorem above. It states that the measure of any exterior angle of a triangle equals the sum of the measures of its remote interior angles.

In this case, <x is an exterior angle. Its remote interior angles are angles B and C. The measure of <x is equal to the sum of the measure of angles B and C.

m<x = m<B + m<C

m<x = 68° + 70°

x = 138

The rate of change for the interval between 2 and 6 on the x-axis is 3.

On a coordinate plane, a parabola opens up.

Solid circles appear on the parabola at (negative 4, 14), (negative 3, 9. 5), (negative 2, 6), (0, 2), (1, 1. 5), (2, 2), (4, 6), (5, 9. 5), (6, 14).

A rate of change defines how one quantity changes in relation to another quantity.

The rate of change for the interval between 2 and 6 on the x-axis is;

\(\rm Rate \ of \ change =\dfrac{2-14}{2-6}\\\\Rate \ of \ change =\dfrac{-12}{-4}\\\\Rate \ of \ change =3\)

We have x = 2.75 meters for the meter stick's shadow and the tree's shadow length is 47.2 meters.

To find the angle of elevation and the height of the tree, we can use similar triangles and trigonometric ratios.

Let's denote the height of the tree as h and the length of the meter stick's shadow as x. According to the given information, we have x = 2.75 meters for the meter stick's shadow and the tree's shadow length is 47.2 meters.

Using the concept of similar triangles, we can set up the following proportion: h / x = tree's height / tree's shadow length

Substituting the given values, we have: h / 2.75 = tree's height / 47.2

To find the angle of elevation, we can use the tangent function: tan(angle) = tree's height / meter stick's height

Substituting the values, we have: tan(angle) = h / 2.75

To solve for the angle, we can take the inverse tangent (arctan) of both sides: angle = arctan(h / 2.75)

f(t) = 3.1667 + 10.8333t, 3.1667 represents the distance Jacob ran during week 5, and 10.8333 represents the increase in distance per week.

Given that Jacob runs 14 miles per day during week 6 and 1.5 miles more per day than he ran during week 5, we can determine the distance he ran during week 5.

Let's say Jacob ran x miles per day during week 5. Therefore, during week 6, he ran x + 1.5 miles per day.

To find the value of x, we know that during week 5, Jacob ran the same distance for 3 days a week. So, the total distance for week 5 would be 3 times the distance he ran each day: 3x.

Similarly, during week 6, Jacob also ran the same distance for 3 days a week, resulting in a total distance of 3 times the distance he ran each day: 3(x + 1.5).

We are given that the total distance for week 6 is 14 miles per day, so we have the equation:

3(x + 1.5) = 14

Expanding and simplifying the equation:

3x + 4.5 = 14

3x = 14 - 4.5

3x = 9.5

x = 9.5 / 3

x = 3.1667 (approximately)

Therefore, Jacob ran approximately 3.1667 miles per day during week 5.

Now, let's find the equation that represents the daily running distance, in miles, as a function of time, t, in weeks.

We know that the distance increases by the same amount each week. So, the increase in distance from week 5 to week 6 is (14 - 3.1667) = 10.8333 miles.

Since Jacob plans to increase the distance by the same amount each week, we divide the increase by the number of weeks:

Increase per week = 10.8333 / (6 - 5) = 10.8333

Therefore, the equation that represents the daily running distance, in miles, as a function of time, t, in weeks is:

f(t) = 3.1667 + 10.8333t

In this equation, 3.1667 represents the distance Jacob ran during week 5, and 10.8333 represents the increase in distance per week.
