Lauren used the Quantitative Reasoning Process to budget and to start a savings account. Each month she makes about $185 from a part-time job. Lauren's parents also send her $120 per month. The sum of Lauren's paycheck and the money she gets from her parents is 11% more than her total expenses. How much money does Lauren have available to add to her savings account each month?

**Lauren** can add $30 each month to her **savings** account

Income made by Lauren from part-time **job **= $185

Money sent to Lauren by her **parents** = $120

Total income of Lauren = Money from job+ money received from parents = 120+185 = $305

Let her total **expenses** be x

Substituting the values in the formula we get:

Sum of Lauren's paycheck + Money she gets from her parents = Total expenses+ 11% more than her total expenses

185 + 120 = x+11% of x

305=x+11/100*x

305 = 1.11x

x=274.77 or 275

Money she can add in her savings account each month = Total money received - Expenses = 305 - 275 = $30

You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 165 km south and 152 km east. Mt. Rainier is located approximately 56 km east and 40 km south of JBLM. If you are flying at a constant speed of 800 km/hr, how long after you depart JBLM will you be the closest to Mt. Rainier?

For the constant **speed**, it take **5 minutes 3 seconds** after you depart JBLM will you be the closest to Mt. Rainier.

Speed:

Speed means a rate of change of **position of an object** in any direction. Speed is measured as the ratio of distance to the **time **in which the distance was covered.

Given,

You're flying from Joint Base Lewis-McChord (JBLM) to an undisclosed location 165 km south and 152 km east. Mt. Rainier is located approximately 56 km east and 40 km south of JBLM.

Here we need to find the time taken after you depart JBLM will you be the closest to Mt. Rainier for the constant speed of 800 km/hr.

Let us consider **+x **direction is east, and the** -y** direction is south.

We know that, JBLM is at the origin (0, 0). All distance units are presented in kilometers.

While we consider that, you are flying on line

165x + 152y = 0

We know that the slope of the line

ax + by = c

is given by -a/b, which suggests we can form the equation of a perpendicular line by swapping x and y coefficients and negating one of them.

Then, we get the equation as,

152x - 165y = c

That is **perpendicular** to the flight path.

Now we need to find c so that this is true at the coordinates of Mt. Rainier.

The perpendicular line through (56, -40) is

152x - 165y - (152(56) - 165(-40)) = 0

When we expand it then we get,

152x - 165y - (8512 + 6600 ) = 0

152x - 165y - 15112 = 0

We know that the distance in km from JBLM (0, 0) to this line is given by

So, when we apply the value of (x,y) as (0,0) then we get,

=> | 152(0) - 165(0) - 15112 |/√(152²+165²)

=> 15112/√50329

=> 15112/224.34

≈ 67.362

Therefore at the constant speed of 800 km/hr, you will have flown that 67. 362 km.

Then for one km you would take,

=> 62.076/800 hr ≈ 0.0842 hr

When we convert this then we get,

=> 0.0842 = 5 minutes 3 seconds.

**Given:**

Initial amount (Base) = 15, 757

Rate of increase = 3.5% or 0.035 in decimal form

**Find: **new price and the price increase

**Solution:**

To be able to get the new price, we need to solve for the price increase first. To do that, we need to know what is 3.5% of the old price 15, 757. To calculate that, we will multiply 0.035 by 15,757.

Hence, by next year, the **new price** will now be 15,757 + 551.50 = **16, 308.50.**

nitrogen has half-life of 15 hours. how much nitrogen will remain in an 18.0 g sample after 60 hours?

If the half-life is 15 hours and there are 18 g, it means that after 15 hours,

18/2 grams would decay, leaving behind 18/2 grams

This means that 9 grams would be left.

After another 15 hours (making a total of 30 hours), 9/2 grams would decay leaving behind 9/2 grams (i.e 4.5 grams.

After another 15 hours (making a total of 45 hours), 4.5/2 grams would decay leaving behind 4.5/2 grams. Hence 2.25 grams are left

After another 15 hours (making a total of 60 hours), 2.25/2 grams would decay leaving behind 2.25/2 grams.

Hence after 60 hours, only 1.125 grams would be left

The **z-score** of a **measure X** of a variable that has **mean **[tex]\mu[/tex] and **standard deviation **[tex]\sigma[/tex] is given by the following equation:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-scoreIn the context of this problem, the **mean **and the **standard deviation** of the heights of American men are given as follows:

[tex]\mu = 69, \sigma = 2.5[/tex]

The proportion of heights that is **greater **than 74 inches is one subtracted by the p-value of Z when X = 74, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (74 - 69)/2.5

Z = 2.5

Z = 2.5 has a p-value of 0.9772.

1 - 0.9772 = 0.0228, hence the **percentage **is of 2.28%. Using the **Empirical Rule,** this percentage is rounded to 2.5%.

The **proportion **of heights **between **64 inches and 71.5 inches is the p-value of Z when X = 71.5, subtracted by the p-value of Z when X = 64, hence:

**X = 71.5:**

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (71.5 - 69)/2.5

Z = 1

Z = 1 has a p-value of 0.84. (rounded with the Empirical Rule).

**X = 71.5:**

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (64 - 69)/2.5

Z = -2

Z = -2 has a p-value of 0.025. (rounded with the Empirical Rule).

What is the horizontaldistance from the fan to home plate? Round to thenearest 10th. Explain two different ways todetermine this distanceB) The same fan makes eye contact with a secondfan in the stands that is seated at a lower row inthe stadium. The straight-line distance betweenthe eyes of the two fans is 300 ft and the angle ofdepression is 48°. What is the vertical distancebetween field level and the eyes of the secondfan? Round to the nearest tenth.

GIVEN:

We are told that a baseball fan is sitting at a point where his eyes are 350 feet vertical distance from the ground. When the fan is looking at the home plate the angle of depression is 30 degrees.

Required;

Find the horizontal distance from the fan to the home plate.

Step-by-step solution;

We begin by making a sketch of the scene to determine the shape and angles formed. This is shown below;

From the sketch above we can see the that the baseball fan has effectively formed a right triangle with the home plate from his position and the dimensions, that is, angles and sides, have been labeled.

We have the reference angle given as 60 degrees and the opposite is x (horizontal distance from the fan to home plate). That means the adjacent side is 350.

We can now use the following trig ratio;

[tex]tan\theta=\frac{opposite}{adjacent}[/tex][tex]tan60\degree=\frac{x}{350}[/tex]We now cross multiply;

[tex]\begin{gathered} tan60\degree\times350=x \\ \\ 1.73205080757\times350=x \\ \\ 606.217782649=x \\ \\ x=606.2ft\text{ }(rounded\text{ }to\text{ }the\text{ }nearest\text{ }tenth) \end{gathered}[/tex]A second way to determine this distance is by using the triangle formed by the angle 30 degrees, in which case the horizontal distance will be the green line as shown in the sketch above. In that case, the vertical distance of 350 feet will be the opposite while the horizontal distance will be the adjacent while the reference angle will be 30 degrees.

For the second scenario, the straight line distance between both sets of eyes is 300 feet, and the angle of depression is 48 degrees. Note that the second fan is being watched at an angle of depression of 48 degrees which means he is at a lower level.

Now we are required to determine the vertical distance between the field level and the eyes of the second fan.

Let us begin by calculating the value of x as indicated in the triangle.

We shall use the trig ratio of;

[tex]cos\theta=\frac{adjacent}{hypotenuse}[/tex][tex]cos42\degree=\frac{x}{300}[/tex]Now we cross multiply;

[tex]\begin{gathered} cos42\degree\times300=x \\ \\ 0.743144825477\times300=x \\ \\ 222.943447643=x \\ \\ x=222.9ft\text{ }(rounded\text{ }to\text{ }the\text{ }nearest\text{ }tenth) \end{gathered}[/tex]Observe carefully that the distance calculated as x (222.9 ft) is the vertical distance between both fans. If we subtract this value from 350 feet we will now derive the vertical distance from the second fan to the field level.

[tex]\begin{gathered} Vertical\text{ }distance=350-222.9 \\ Vertical\text{ }distance=127.1ft \end{gathered}[/tex]Therefore,

the graph of a quadratic function is given. determine the function's equation.

[tex]f(x)=(x+2)^2\text{ + 2}[/tex]

Here, we are given a quadratic equation graph and we are tasked with getting the equation of the quadratic equation from the graph

The first thing we need to note here is the shape of the parabola.

This in the sense that if the parabola opens up or faces down

On the graph we can see that the parabola faces the positive x-direction

Generally, the equation of a quadratic graph is usually in the form below;

[tex]y=ax^2\text{ + bx + c}[/tex]So by identifying the values of a,b and c, we can get the complete equation of the graph

The above form is called the standard form while the form we have in the options is referred to as the vertex form

The vertex form can be written as;

[tex]y=a(x-h)^2\text{ + k}[/tex]Now, looking at the graph, we can see that the graph crosses the y-axis at the point y = 6

At this point, the value of x is 0

The vertex (h,k) represents the center point of the parabola

In the case of this question, the point is (-2,2)

so h =-2 and k is 2

What is left is to get a

we can obtain this from the value of y = 6 and x = 0

Thus;

6 = a(0-(-2))^2 + 2

6 = a(2)^2 + 2

6 = 4a + 2

4a = 6-2

4a = 4

a = 4/4 =1

So the equation in the vertex form is f(x) = (x + 2)^2 + 2

Given g(-2) = -4 and g'(-2) = 5, find the value of h'(-2) based on the function below.

h(x) = (-2x + 6) • g(x)

**Step-by-step explanation:**

so,

h(x) = f(x) × g(x)

h'(x) = f'(x) × g(x) + f(x)×g'(x)

with f(x) = -2x + 6

f'(x) = -2

so,

h'(-2) = -2 × g(-2) + (-2×-2 + 6) × g'(x) =

= -2 × -4 + 2 × 5 = 8 + 10 = 18

The absolute value **function **y = 3|x + 1| + 9 is y ≥ (x + 4)/3 when x ≥ 0 and

y > - (x - 2)/3 when x < 0.

What is the absolute value function?The absolute value function always outputs a positive value **irrespective** of the input.

Given we have to write the absolute value function as a **piecewise **function.

We know | x | = a implies x ≥ a and - x < a.

y = 3| x + 1 | + 9.

y - 9 = 3| x + 1|.

(y - 9)/3 = | x+ 1 |.

∴ (y - 9)/3 ≥ x + 1.

y/3 - 3 ≥ x + 1.

y/3 ≥ x + 4.

y ≥ (x + 4)/3.

**OR**

(y - 9)/3 = | x+ 1 |.

- (y - 9)/3 < x + 1.

-y/3 + 3 < x + 1.

-y/3 < x - 2.

-y < (x - 2)/3.
