Step-by-step explanation:

A triangular prism, a shape with two identical triangular faces and three identical rectangular faces, has 6 vertices where the edges of these faces meet.

In geometry, a shape's vertices are the points where two or more lines or edges meet. When we consider a triangular prism, we see that it is a figure with two triangular faces and three rectangular faces. Each triangular face has 3 vertices, and since these faces are identical, they share vertices. If you count up all these points, we find that a triangular prism has 6 vertices in total.

Answer:

ADB CBD 1

Step-by-step explanation:

Initial bacteria count is 3, as it doubles every 12 hours; after 2 days, totaling 48 bacteria.

To solve this problem, we can use the formula for exponential growth, which is  

[tex]- \( N \)[/tex]is the final number of bacteria,

[tex]- \( N_0 \)[/tex] is the initial number of bacteria,

[tex]- \( t \)[/tex] is the elapsed time in hours, and

[tex]- \( d \)[/tex] is the doubling time in hours.

Given that the doubling time is 12 hours and after 2 days (which is 48 hours) there are 48 bacteria, we can plug these values into the formula and solve for [tex]\( N_0 \):[/tex]

[tex]\[ 48 = N_0 \times 2^{(48/12)} \][/tex]

Solving this equation:

[tex]\[ 48 = N_0 \times 2^4 \][/tex]

[tex]\[ 48 = N_0 \times 16 \][/tex]

Now, to find [tex]\( N_0 \)[/tex]:

[tex]\[ N_0 = \frac{48}{16} \][/tex]

[tex]\[ N_0 = 3 \][/tex]

So, there were 3 bacteria at the beginning of the first day.

Answer:

r = 4.5m

d = 57 yds

Step-by-step explanation:

The radius is 1/2 of the diameter

d= 9 meter

  r = d/2  =9/2 = 4.5 m

The diameter is twice the radius

r = 28.5 yds

d = 2r = 2*28.5 =57 yds

Answer:

a) r=4.5 m

b) d= 57 yd

Step-by-step explanation:

a)

The diameter is twice the radius, which can be written as:

d=2r

We know the diameter is 9, so we can substitute that in for d.

9=2r

To solve for r, we need to isolate the variable. To do this, divide both sides by 2

9/2=2r/2

4.5=r

So, the radius is 4.5 meters

b)

The diameter is twice the radius, or

d=2r

We know the radius is 28.5, so we can substitute that in for r

d=2*28.5

Multiply

d=57

So, the diameter is 57 yards

Answer:

$34.20

Step-by-step explanation:

First, find the cost with tax

You are paying 7.2% tax, but you are also paying for 100% of the bill

100%+7.2%=107.2%

So, you are really paying for 107.2% of the bill

Convert 107.2% to a decimal by dividing by 100 or moving the decimal 2 spaces to the right

107.2/100=1.072

Multiply the decimal by the cost of the bill

1.072*45.90=49.2048

But, we also have a coupon for $15 off

Subtract 15 from the cost with tax

49.2048-15=34.2048

Round to the nearest cent/hundreth

$34.20

5ft long rectangle

The designer want to increase the length,

Then, there will be 3 identical rectangle of total length of 17ft

By how much did he increase the of each rectangle

Original, the length of the rectangle is 5ft, now, we want to design three rectangle. This three identical rectangle will have total length of (5+5+5)ft,

The original length of the three rectangle is meant to be 15ft,

Now he increase the length to 17ft,

This shows that he has increase all the three rectangle by 2ft.

So, each rectangle is expected to be increased by ⅔ft

So, he increased each rectangle length by ⅔ft.

Mathematically,

Let the increase be x

Then, he increase each length by x, so the new length is

5+x

Then, there are 3 rectangles, so their total length after increase is 3×(5+x)

And this total length after increase is give as 17ft

Then,

3(5+x) = 17

Solving this

15 + 3x = 17

3x = 17-15

3x = 2

x = ⅔ ft

So, the mathematical model of the increase is 3(5+x) = 17 and the increase is ⅔ft

Answer:

The predicted percentage vote for Al Gore for the county with 44.0954% African Americans is 25.76%.

Step-by-step explanation:

The least square regression line is used to determine the relationship between a response variable (or dependent variable) and an explanatory variable (or independent variable).

The least square regression line can be used to predict the future value or estimate the past value of the dependent variable based on the independent variable.

The general form of a least square regression line is:

[tex]y=\alpha +\beta x[/tex]

Here,

y = response variable

x = explanatory variable

α = intercept

β = slope

The least square regression line for predicting the percentage vote for AI Gore (y) from the percentage of county residents who were African American (x) is given by:

[tex]\hat y=25.4495+0.6956 x[/tex]

Compute the predicted value of y for x = 44.0954% = 0.440954 as follows:

[tex]\hat y=25.4495+0.6956 x[/tex]

  [tex]=25.4495+0.6956 \times 0.440954\\=25.4495+0.3067276024\\=25.7562276024\\\approx 25.76[/tex]

Thus, the predicted percentage vote for Al Gore for the county with 44.0954% African Americans is 25.76%.

Using the equation of the estimated regression line, the predicted percentage vote for Al Gore in Baker County, Georgia is approximately 56.3555% based on a population that was 44.0954% African American.

In this scenario, we have a linear regression line of the form y^ = 25.4495 + 0.6956x, where y^ represents the estimated percentage vote for Al Gore, and x represents the percentage of county residents who are African American. We are given that in Baker County, Georgia, 44.0954% of residents are African American. By substituting this x value into the equation, we can find the predicted y value:

y^ = 25.4495 + 0.6956*(44.0954)

This gives an estimated vote for Al Gore in Baker County as y^ = 56.3555 approximately, to four decimal places. This implies that the model predicts that about 56.3555% of the vote in Baker County went to Al Gore.

Steve should use:

Step-by-step explanation:

Let Steve cut the wire so that the first piece has length x.

Therefore, the second piece will have a length of (52 - x).

The wire of length x is used to make a circle

Circumference of a Circle,

[tex]c = 2\pi r\\Therefore\\2\pi r=x\\r=\dfrac{x}{2\pi}[/tex]

[tex]\text{Area of a circle, A}=\pi r^2= \pi (\dfrac{x}{2\pi})^2=\pi (\dfrac{x^2}{4\pi^2})\\A=\dfrac{x^2}{4\pi}[/tex]

The wire of length (52-x) is used to make a square.

[tex]\text{Side length of the Square,}[/tex] [tex]s= \dfrac{52-x}{4}[/tex]

[tex]\text{Area of the Square},s^2= \left(\dfrac{52-x}{4}\right)^2=\dfrac{(52-x)^2}{16}=\dfrac{x^2-104x+2704}{16}[/tex]

Total Area = Area of Circle + Area of Square

[tex]Area=\dfrac{x^2}{4\pi}+\dfrac{x^2-104x+2704}{16}[/tex]

Let us simplify the expression

[tex]Area=\dfrac{16x^2+\pi(x^2-104x+2704)}{16\pi}\\=\dfrac{16x^2+\pi x^2-104\pix+2704\pi}{16\pi}\\=\dfrac{x^2(16+\pi)-104\pi x+2704\pi}{16\pi}\\=\dfrac{x^2(16+\pi)}{16\pi}-\dfrac{104\pi x}{16\pi}+\dfrac{2704\pi}{16\pi}\\A=\dfrac{x^2(16+\pi)}{16\pi}-6.5x+169[/tex]

Consider the triangles.

Triangle C D E. Angle C is blank, angle D is 87.3 degrees, angle E is 35.5 degrees. Triangle R S T. Angle R is blank, angle S is 57.2 degrees, angle T is 87.3 degrees.

Answer the questions about these triangles.

What is the measure of angle C?

✔ 57.2

Which angle corresponds to angle C?

✔ angle S

What can be concluded about the triangles?

✔ The triangles are similar.

The measure of angle C in triangle CDE is 57.2 degrees, Angle C corresponds to angle R in triangle RST,  and the two triangles are  similar or congruent.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Since the sum of angles in a triangle is always 180 degrees, we can find the measure of angle C in triangle CDE by subtracting the measures of angles D and E from 180 degrees:

Angle C = 180 degrees - Angle D - Angle E

Angle C = 180 degrees - 87.3 degrees - 35.5 degrees

Angle C = 57.2 degrees

Therefore, the measure of angle C in triangle CDE is 57.2 degrees.

Angle C corresponds to angle R in triangle RST, since they are both unknown angles in their respective triangles.

We can conclude that the two triangles are  similar or congruent.

Hence, the measure of angle C in triangle CDE is 57.2 degrees, Angle C corresponds to angle R in triangle RST,  and the two triangles are  similar or congruent.

Step-by-step explanation:

a. Given the initial amount is $40,000 with a 3-year term and a 6% rate compounded daily.

-Take 1 year=365 days

#First we calculate the effective interest rate corresponding to the daily compounding;

[tex]i_m=(1+i/m)^m-1\\\\=(1+0.06/365)^{365}-1\\\\=0.06183[/tex]

#We use the calculated effective rate, 0.06183, to solve for the future value as:

[tex]A=P(1+i_m)^n\\\\=40000(1.06183)^3\\\\=47887.81[/tex]

Hence, the total future value for a daily compounding is $47,887.81

b. For a sinking fund with a 5% compounded quarterly:

#We calculate the annual effective rate:

[tex]i_m=(1+i/m)^m-1\\\\=(1+0.05/4)^4-1\\\\=0.05095[/tex]

#We use the calculated effective rate, 0.05095, to solve for the future value as:

[tex]A=P(1+i_m)^n\\\\=40000(1.05095)^3\\\\=46430.80[/tex]

Final answer:

The distributive property states that the product of a number and a sum is equal to the sum of the individual products. In this situation with the cars, we can use the distributive property to calculate the total number of people in all the cars.

Explanation:

The distributive property in mathematics states that the product of a number and a sum is equal to the sum of the individual products. In this situation with the cars, we can use the distributive property to calculate the total number of people in all the cars. Each car has 2 people in front and 3 people in back, so we can write the expression as (2 + 3) * 6. Using the distributive property, we can simplify this expression to 2 * 6 + 3 * 6, which equals 12 + 18, or 30 people in all the cars.

V=4/3πr3

The volume of sphere when rounded to nearest 100th will be 2143.574 cubic units

Given: a sphere of radius 8 units

To find: Volume of sphere

The volume of a sphere can be calculated using the formula [tex]V = \frac{4}{3}\pi r^3[/tex], where r is the radius of the sphere. To find the volume, plug in the value of the radius into the formula and calculate the result.

[tex]V = \frac{4}{3}\pi r^3\\[/tex]

[tex]V = \frac{4}{3}\pi (8)^3\\[/tex]

[tex]V = \frac{4}{3}\pi (8)^3 = 682.667 \pi[/tex]

If we insert the value of [tex]\pi = 3.14[/tex] we get:

[tex]V = 682.667 \times 3.14 = 2143.57438[/tex]

When rounded to nearest 100th we will get volume equal to 2143.574 cubic units.
