The amount that needs to be deposited to have a saving of $50,000 in 30 years at the given interest rate is $8,302.10.

The compound interest formula is expressed as;

P = A / (1 + r/n)^nt

Where P is principal, A is amount accrued, r is interest rate is compound period and t is time elapsed.

Given the data in the question;

First, convert rate from percent to decimal.

Rate r = 6%

Rate r = 6/100

Rate r = 0.06 per year

To determine the principal, plug the given values into the formula above and solve or P

P = A / (1 + r/n)^nt

P = $50,000 / (1 + 0.06/12)^( 12 × 30 )

P = $50,000 / (1 + 0.05)³⁶⁰

P = $50,000 / (1.05)³⁶⁰

P = $8,302.10

Therefore, the principal investment is $8,302.10.

Answer:

have you heard of the genger bread man

Step-by-step explanation:

A motion sensor, sometimes known as a motion detector, is a piece of technology that use a sensor to find nearby individuals or objects. Any security system needs motion sensors as a crucial part. A sensor will alert your security system and, with newer systems, your cell phone when it senses motion.

How does a motion sensor function?

Active ultrasonic motion detectors emit ultrasonic sound waves, which bounce off surrounding objects and return to the source of emission. The sensor initiates and completes the required action, whether it be turning on a light or sounding an alert, when a moving object interferes with the waves.

Answer:

k = 4

Explanation:

1) The triangles in example 1 are similar triangles but differs in size

We are to calculate the scale factor k

Using the formula

Scale factor k = size of the larger triangle/size of the smaller trinagle

Since they are similar triangles;

k = DF/AB

Given

DF = 48

AB = 12

Substitute the given values into the expression for k above to have;

k = 48/12

k = 4

Hence the scale factor from triangle ABC to DEF is 4

Answer:

[tex]y=\frac{-1}{3}x+5[/tex]

Answers being -1/3 and 5

Step-by-step explanation:

In slope-intercept form, you seem to be missing your slope and intercept.  Luckily, the graph has everything you need.

Recall slope is rise over run or y over x.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

The slope of this line can be determined by counting the x and y movements of the line between two intersections where it evenly collides.  For instance, between (0,5) and (3,4), the line moves right three and down one.  

This would give you a slope of -1/3.

Another way to find the slope is to choose any two points and use the slope formula above.  Using those same two points:

[tex]m=\frac{4-5}{3-0}[/tex]

[tex]m=\frac{-1}{3}[/tex]

Now you have the first part of your answer.  The slope is -1/3.

The second part is the y coordinate of the y-intercept.  In this case, the graph includes the intercept, which we can clearly determine is (0,5).  Therefore, your second answer would be 5.

The full answer being [tex]y=\frac{-1}{3}x+5[/tex].

If She was entitled to a personal exemption of $2900 and had deductions totaling $5090. her gross income is $36,100, adjusted gross income is  $33,400 , and taxable income is $25,410.

Gross Income:

Gross Income= Wages + Interest received

Gross Income= 34,600 + $1500

Gross Income= $36,100

Adjusted Gross Income:

Adjusted Gross Income  = Income - Tax Def Contribution

Adjusted Gross Income = $36,100- $2,700

Adjusted Gross Income = $33,400

Taxable Income :

Taxable Income = AGI - Deductions - Personal exemption

Taxable Income= $33,400- $5,090 - $2,900

Taxable Income= $25,410

Therefore her  gross income is $36,100.

The length of the three sides of the triangle are 11 feet, 12 feet and 15 feet.

A triangle is a polygon with three sides.

The perimeter of a triangle is 38 feet.

The perimeter of the triangle is the sum of the whole three sides.

One side of the triangle is one foot longer than the second side.

let

the second side = x

longer side = x + 1

The third side is four feet longer than the second side.

Hence,

Third side = 4 + x

Therefore,

38 = x + x + 1 + x + 4

38 = 3x + 5

3x = 38 - 5

3x = 33

x = 33 / 3

x = 11

Therefore, the sides of the triangle are 11 ft, 12 feet and 15 ft.

    A line's x-intercept and y-intercept are the points at which the x- and y-axes, respectively, are crossed. We find it easier to graph linear equations when we consider intercepts.

    Where a line on a graph crosses the x-axis is known as the x-intercept. At that time, the y coordinate's value is zero. For instance, the x-intercept would be where the equation y = x + 5 crosses the x-axis at the location (-5, 0).

      We set y = 0 and solve the equation for x to determine the x-intercept. This is due to the fact that the line crosses the x-axis at y=0. If an equation is not in the form y = mx + b, we can still solve for the intercepts by substituting 0 where necessary and then solving for the final variable.

        This is an illustration of a y-intercept. Think about the line y = x + 3. The point where this graph crosses the y-axis is (0,3). Therefore, the y-intercept of the line y = x+ 3 is (0,3).

       If you can locate the x-intercept of a linear function, finding the zero should be simple. The x-coordinate of the x-intercept is zero.

Summary

         Consider the numbers as being on the x-axis to help you remember this. The positive values are located to the right of the origin, and the negative values are located to the left of the origin.

Given that

The population of a certain city is 1.50 million initially and it gets increased by 6.5% exponentially. And we have to find the number of years in which the population becomes 2.31 million.

Explanation -

The formula for the exponential growth is given as

Here we have f(x) = 2.31 million, a = 1.50 million , r = 6.5% and x = ?

So let the time be t.

Then, on substituting the values we have

The formula for radius is

radius = diameter/2

If diameter = 5, then

radius = 5/2

radius = 2.5

The angle m∠FCD is 56°

Here the line CF is an angle bisector of ∠GCD.

By this we have,

∠GCF = ∠FCD

It is given that

∠GCF = ∠GCB - 12°

Let ∠GCB be x.

∠GCF = x - 12° = ∠FCD

BCD is a straight line which form 180°.

∠BCG + ∠GCF + ∠FCD = 180°

x + x - 12° + x - 12° = 180°

3x = 204°

x = 68°

∠FCD = x - 12°

          = 68° - 12°

          = 56°

Therefore m ∠FCD = 56°.

Transformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation.

Translation is a method of transformation that involves moving an object or shape from one point to another without changing any dimension.

Reflection is a method of transformation that involves flipping a given figure about a given reference point or line. In order words, a mirror image of the original object.

Rotation is a method of transformation that involves  turning a given figure at an angle about a reference point.

Dilation is a method of transformation whereby the length of the sides of the figure is either increased or decreased.

A) When James spins a basketball on his finger, it is clear that this transformation is rotation because it involves turning the ball at an  angle about a given point.

Proportionately, the total number of registered doctors, based on the ratio of female doctors, is 150,637.

Proportion refers to the quantity relationship of a variable contained in another.

Using proportion, two values are equated to each other.

For instance, we equate the percentage of registered female doctors to the number of registered female doctors.

Proportions, like ratios, are stated as fractions, decimals, or percentages because they depict the portion of a variable in another.

The ratio of registered female doctors = 31.4%

The number of registered female doctors = 47,300

31.4% = 47,300

100% = 47,300/31.4% x 100

The total number of registered doctors = 150,637  (47,300/31.4%)

Thus, the total number of registered doctors is 150,637, given that 47,300 female registered doctors proportionately represent 31.4% of the population.
