Of the birds in Monica's pet shop, 1/5 are pigeons. Of the pigeons, 1/3 are white. Look at each expression. Can it be used to find the fraction of birds in Monica's pet shop that are white pigeons?

Answers

1/15 of the birds are white

1/15.

The expression that can be used to find the fraction of birds in Monica's pet shop that are white pigeons is:

1/5 x 1/3 = 1/15

This calculation is derived by multiplying the fraction of pigeons in the pet shop (1/5) by the fraction of white pigeons among pigeons (1/3).

The height, h, of a falling object t seconds after it is dropped from a platform 300 feet above the ground is modeled by the function h(t)=300-16t2. Which expression could be used to determine the average rate at which the object falls during the first 3 seconds of its fall.

Answers

your average speed is the average difference over time (in this case 3 seconds)

[tex] \frac{h(3)-h(0)}{3}=\\ \frac{300-16*3^2-(300-16*0^2)}{3}=\\ \frac{300-16*3^2-(300)}{3}=\\ \frac{-16*3^2}{3}=\\ -16*3=-48[/tex]




Answer:

-96 feet/sec.

Step-by-step explanation:

The height h of a falling object after t second when it is dropped from a platform 300 feet above the ground is modeled by the function h (t) = 300 - 16t²

Then speed or average rate by which the object falls from height h will be [tex]\frac{d[h(t)]}{dt}=\frac{d(300-16t)^{2} }{dt}[/tex]

Speed = [tex]\frac{d}{dt}(300)[/tex] - [tex]\frac{d}{dt}(16t^{2} )[/tex]

         = -16 (2t)

Speed = -32t

After 3 second speed of object will be

Speed = -32(3)

          = -96 feet/second

Therefore, the average rate will be -96 feet/sec. during the first 3 seconds of its fall.

Solomon is taking out a 5,320 two year loan with an APR of 10.25%. What will the finance charge be for this loan to the nearest dollar?

Answers

We know that APR means Annual Percentage Rate, so in one year we should pay that rate for the loan amount: $5,320 * 10.25 % = $5,320 * 10.25/100 = $545.30 per year Due that Solomon took the loan for 2 years, the finance charge will be: $545.30 * 2 year = $1,090.60 Rounded to the nearest dollar is: $1,091 That means after two year Solomon will have returned the loan plus the charge: $5,320 + $1091 = $6,411

What is the area of the region of the complex plane defined by $|z|<5$?

Answers

This will be the same area as that inside a circle with a radius of 5

 

So....the area will  be  ≈  pi * 5^2  ≈    25 pi  units^2

 

Final answer:

The area of the region of the complex plane defined by |z|<5 is 78.5 square units.

Explanation:

The region of the complex plane defined by |z|<5 is the inside of the circle with radius 5 centered at the origin. To find the area of this region, we can use the formula for the area of a circle, which is A = πr². In this case, the radius is 5, so the area is A = 3.14 × 5² = 78.5 square units.

When adding two numbers, such as 123 and 423, care is taken to first line them up and then add like digits. How does expanding this expression to [(1 × 102) + (2 × 101) + (3 × 100)] + [(4 × 102) + (2 × 101) + (3 × 100)] make the operation more like a polynomial addition problem?

Answers

Think of 10^2, 10^1, and 10^0 as x^2, x^1, and x^0.
When you add polynomials, you can only combine like terms.
When you add expanded numbers, you can only combine like powers of 10.

123 + 423 =

= (100 + 20 + 3) + (400 + 20 + 3)

= (1 * 10^2 + 2 * 10^1 + 3 * 10^0) + (4 * 10^2 + 2 * 10^1 + 3 * 10^0)

= (1 * 10^2 + 4 * 10^2) + (2 * 10^1 + 2 * 10^1) + (3 * 10^0 + 3 * 10^0)

= 5 * 10^2 + 4 * 10^1 + 6 * 10^0

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −7 0 −1 1 5 g(x) g(x) = 5x − 4 Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) Part B: Which function has a greater y-intercept? Justify your answer. (4 points)

Answers

Question A:

Rewriting the table for f(x):

x      -1       0      1
f(x)   -7      -1      5

Notice that for every increase of one unit in 'x', there are an increase 6 units on f(x). Hence, the gradient of the slope of f(x) is 6. 

g(x) = 5x - 4 ⇒ This function follows the general form of the straight line equation, y = mx + c, where 'm' is the gradient and 'c' is the y-intercept.
Hence, the gradient of the slope of g(x) is 5.

The slope of f(x) is steeper than the slope of g(x).

---------------------------------------------------------------------------------------------------------------

Question B:

The y-intercept is the value of y where a straight line crosses the y-axis (or when x is zero).

From the table of f(x), the y-intercept is -1 (this is the value of 'y' when 'x' is zero)

From the given function g(x) = 5x - 4, the y-intercept is -4. 

f(x) has a greater y-intercept.

Rachel deposited $6,449.82 into a savings account with an interest of 6.9% compounded annually. About how long will it take for the accout to be worth $8,000?

Answers

Answer:

3 years and 3 months.

Step-by-step explanation:

Since, the amount formula in compound interest,

[tex]A= P(1+\frac{r}{100})^t[/tex]

Where,

P = principal amount,

r = rate per period,

t = number of periods,

Here, A = $ 8,000, r = 6.9%, P = $6,449.82,

By substituting the values,

[tex]8000 = 6449.82(1+\frac{6.9}{100})^t[/tex]

[tex]\frac{8000}{6449.82}=(1+\frac{6.9}{100})^t[/tex]

[tex]\ln (\frac{8000}{6449.82})=t\ln(1.069)[/tex]

[tex]\implies t = \frac{\ln (\frac{8000}{6449.82})}{\ln(1.069)}=3.228[/tex]

Hence, it would be take 3.228 years or 3 years and 3 months.

Given: M is the midpoint of LN; LM =8 prove:LN=16

Answers

A midpoint divides a segment into two congruent segments.

If LM = 8, then MN = 8.

Adding both together, you would get 16 for the length of LN.

The proof of LN= 16 is shown below:

What is midpoint?

The midpoint formula is applied when one is required to find the exact center point between two defined points. So for a line segment, use this formula to calculate the point that bisects a line segment defined by the two points.

Given:

LM= 8

and M is the midpoint of LN

So, the line LN will be break into two equal parts LM and MN

then we can write

LM= MN= 8

Now,

LN= LM+ MN

LN= 8+8

Kendall is stacking boxes that are 7.5inches tall. Explain how to find the height (in inches)

Answers

You can find the height by finding out the number of boxes and plugging it into an equation.  Height = 7.5(Number of Boxes)

Final answer:

To find the height of stacked boxes, multiply the height of one box (7.5 inches) by the total number of boxes stacked.

Explanation:

Kendall is stacking boxes that are each 7.5 inches tall. To find the total height in inches of the stacked boxes, you would need to multiply the height of one box by the total number of boxes stacked. For example, if Kendall stacks 10 boxes, the calculation would be 7.5 inches x 10, which equals 75 inches. Therefore, the total height of the 10 stacked boxes would be 75 inches.
