1. Ms. Oates is going to plant grass in her backyard. It is 14feet wide and 20.5 feet long. What is the area of thebackyard that will need to be covered with grass?

Hello there. To solve this question, we'll have to remember some properties about set up an equation and solving them.

"Let y be an unknown number. 18 times a number minus 97 is equal to 9 less than the number."

We need to find this number.

Starting with the equation:

On the left hand side, we have 18y as 18 times the number, then subtracted 97 for the minus 97 part. On the right hand side, 9 less than the number is represented as the number minus 9.

So, subtract y - 97 on both sides of the equation

Divide both sides of the equation by a factor of 17

This is the number we've been looking for.

1. At age 65 when you retire, you have (future value) $202,531.69 from the IRA.

2. The total interest earned on the monthly investment of $95 at 6.25% for 40 years is $156,931.69.

The future value, which represents the compounded value of the monthly investments, can be computed using the FV formula or an online finance calculator as follows:

Number of years = 40 (65 - 25)

N (# of periods) = 480 months (40 x 12)

I/Y (Interest per year) = 6.25%

PV (Present Value) = $0

PMT (Periodic Payment) = $95

Results:

Future Value (FV) = $202,531.69

Sum of all periodic payments = $45,600 ($95 x 480 months)

Total Interest = $156,931.69

Thus, the future value of the monthly investment is $202,531.69 with an interest of $156,931.69.

For this problem, we need to describe a real-life situation where trigonometric functions can be used to model the problem.

Let's assume that a certain vehicle's position is controlled by the speeds of the wheels on each side of the car. Whenever the speeds on the left wheels and right wheels are equal, then the car moves forward, if the speed on the left side is greater than the one on the right side the car goes right, and if the speed on the right side is greater, then the vehicle goes to the left side. This type of car is called a differential drive car, and it's very common on remote-controlled (RC) vehicles.

If we want to model the speed of the car in a two dimensional grid, such as below:

We need to assume that the vehicle will have two components of velocity, one that is parallel to the x-axis and one that is parallel to the y-axis. These will form the linear velocity for the vehicle. We also need an angular velocity, which is the rate at which the angle of the vehicle changes.

If we assume that the wheels of the vehicles are at a distance of "L" apart from each other, then we can model the angular velocity of the vehicle as:

Where "vr" is the speed on the right wheel, and "vl" is the speed on the left wheel. The movement will happen with the center of the car as the center of the movement, with this we can assume that the velocity of the vehicle on the two axes should be:

Therefore we can describe the vehicle speed with the following equations:

The input variables are "vr" and "vl" which are the speeds of each wheel and the angle of the vehicle "theta", the output is the speed at the x coordinate and the speed at the y coordinate, and the angular speed.

This works very well because if the vehicle is moving parallel to the x-axis, the angle will be 0, the cosine of 0 is 1, therefore the speed on the y axis will be 0 and the speed on the x-axis will be given by 0.5(vr+vl). The opposite happens when the vehicle is moving parallel to the y-axis.

To obtain the slope of the line that passes through the two given points, the following steps are recommended:

Hello there. To solve this question, we'll have to remember which other formulas for area of triangles can be used.

Most specifically, it asks for a formula that works on an obtuse triangle, that is, a triangle that haves an angle that measures more than 90º.

Besides the formula BH/2, that refers to half of the product between the measurements of the base and the height of the triangle, of course, this height must be a projection perpendicular to the base, as in the following drawing:

Another formula that can be used is Heron's formula;

Knowing the measures of all the sides of the triangle (no matter if it is an obtuse, acute or right triangle), say a, b and c, Heron's formula states that the area S of the triangle is given by:

Where

Sum of the exterior angles of a polygon = 360°

For a regular polygon, all the angles are equal:

mn = 360

where n = the number of sides

m = the size of an exterior angle

For m = 15°

15n = 360

n = 360/15

An ordered pair for the equation 5x + y = 1 is (0, 1)

The equation of the function is given as

5x + y = 1

To determine the ordered pair, we simply set the value of x to any value.

And then calculate the value of y

Using the above parameters as a guide, we can assume that

Substitute x = 0 in 5x + y = 1

5(0) + y = 1

Evaluate the product

Remember that a function is a relation between two sets of numbers where the first set is called domain, and the second set is called range.

The main characteristic that defines a function is that a domain element can be associated with only one element of the range set. In other words, one input value cannot have two different output values.

Therefore, the right answer is the third choice

y represents the distance of the snail to the flower, in ft

x represents time, in hours

In the beginning, the distance of the snail to the flower is 7 feet. Then, the point (0, 7) is on the graph

After the first hour, the snail crawls 2 feet, then its distance to the flower is 7 - 2 = 5 ft. Then, the point (1, 5) is on the graph.

After the second hour, the snail crawls another 2 feet, then its distance to the flower is 5 - 2 = 3 ft. Then, the point (2, 3) is on the graph.

After the third hour, the snail crawls another 2 feet, then its distance to the flower is 3 - 2 = 1 ft. Then, the point (3, 1) is on the graph.

Answer:

Angle Reason

m∠ECD = 140 Given

m∠ECB = 40 Supplementary angles

m∠EBC = 70 Isosceles triangle

m∠ABE = 110 Supplementary angles

Explanation:

Angle ECB and CED are supplementary because they form a straight line and their sum is 180 degrees. So, we can calculate the measure of ∠ECB as

m∠ECB = 180 - 140

m∠ECB = 40

Then, the interior sum of the angles of a triangle is equal to 180 degrees, so

m∠ECB + m∠EBC + m∠BEC = 180

40 + m∠EBC + m∠BEC = 180

However, m∠EBC = m∠BEC because triangle ABC is an isosceles triangle where 2 sides have the same length BC and EC. So, we can find m∠EBC as follows

40 + m∠EBC + m∠EBC = 180

40 + 2m∠EBC = 180

40 + 2m∠EBC - 40 = 180 - 40

2m∠EBC = 140

m∠EBC = 140/2

m∠EBC = 70

Then, the measure of ∠ABE is equal to

∠ABE = 180 - m∠EBC

∠ABE = 180 - 70

∠ABE = 110

Therefore, we can answer it as follows

Angle Reason

m∠ECD = 140 Given

m∠ECB = 40 Supplementary angles

There are a total of 4 outcomes that involve choosing a blue marble

Here, we want to write a sample space for the selection

For us to have the sample space, we will have to write out the possible outcomes

We shall be representing the blue marble by b, the green by g and the yellow by y

We have the sample space as follows;

From the sample space, we can see that there are actually 12 possible results

Now, to get the outcomes involving blue marbles, we simply select the members of the sample space having B at the back

We have these as 1B, 2B, 3B and 4B

Final answer:

Answer:

35 degrees.

Explanation:

The figure shown is an isosceles triangle. An isosceles triangle has two of its sides and base angles to be equal.

Since the sum of the angles in a triangle is 180 degrees, hence:

110 + (base angles) = 180

110 + (<1 + <1) = 180 (since base angles are the same)

110 + 2<1 = 180

2<1 = 180-110

2<1 = 70

Divide both sides by 2

2<1/2 = 70/2

<1 = 35 degrees

Hence the angle between an eave and the horizontal support beam is 35 degrees.
