“The height of an arrow” NEED HELP WITH THIS QUESTION ASAP!

Answers

Answer:

a) t = 0.54 seconds

b) t = 8 seconds

Step-by-step explanation:

Given in the question the equation

h = 40t - 5t²

where h is height in meters

            t is time in seconds

Time it took to reach 20 meters

20 = 40t - 5t²

-5t² + 40t - 20 = 0

by using quadratic formula for factorisation

t = (-b± √(b)² - 4(a)(c) ) / 2(a)

t = 0.54 (upward motion)

or

t = 7.46 (downward motion)

b) Time it took to reach the ground

at ground h = 0

So,

0 = 40t - 5t²

t(40 - 5t ) = 0

t = 0 (at starting point)

or

40 -5t = 0

5t = 40

t = 40 /5

t = 8 seconds

Plz help me out fams

Answers

Answer: for #1. 10.5 cups of water. For #3. 55 people

Step-by-step explanation:

You must take the total amount of fluid ounces and divide it by how many ounces in a cup, which is 8.

You must divide the amount of people that tested positive by the percentage (as a decimal) of people tested. In this case, it would be 22 divided by 0.4.

0.5 as hundredths in fraction form and decimal form

Answers

Answer:

5/100, .05

Step-by-step explanation:

The decimal form remains 0.5, but when expressed with a denominator of 100, it becomes 50.0%.

To express 0.5 as hundredths in fraction form, you convert the decimal to a fraction with a denominator of 100. Since 0.5 is equivalent to 50%, you would write this as 50/100. This fraction can also be simplified to 1/2 by dividing both the numerator and the denominator by 50.

In decimal form, 0.5 is already represented as a decimal and does not require conversion. However, if we are to express it with a denominator of 100, we simply move the decimal point two places to the right (multiplying by 100), yielding 50.00, which can then be represented as 50.0% when expressing as a percent.

a circualr plate haa circumference 22.6 inches.What is the area if this plate? use 3.14​

Answers

40.7in^2

Circumference = 2pi*r

22.6 = 2*3.14*r

22.6 = 6.28*r

r = ~3.6

Using that we can find area

A = pi*r^2

A = 3.14*3.6^2

A = 3.14*12.96

A = 40.6944 which is ~40.7in^2

The area of the circular plate with a circumference of 22.6 inches is 40.69 in².

How to find the area of a circle?

The area of a circle can be found by using the formula given below:

Area = πr²

The area of the circle can be found as given below:

The circumference is given as 22.6. Therefore:

Circumference = 2πr

⇒ 22.6 inches = 2πr

⇒ 22.6 inches = 2*3.14*r

⇒ r = 22.6/(2*3.14) inches

⇒ r = 3.6 inches

We can use this r to find the area. The area of a circle is given by:

A = πr²

= 3.14*3.6*3.6 in²

= 40.69 in²

Therefore we have found the area of the circular plate with a circumference of 22.6 inches to be 40.69 in².

Bacteria X has a growth rate of 180 % per hour. Some amount of bacteria X are accidentally introduced into some egg salad. Three hours after contamination, there were 35,000 bacteria X in the egg salad.

Find the initial number of bacteria X introduced into the egg salad?
Estimate the number of bacteria in the food 4 hours after contamination?

Answers

There were about 6001 bacteria X bring introduced into the egg salad. The number of bacteria in the food 4 hours after contamination is 63000.

Final answer:

To find the initial number of bacteria X introduced into the egg salad, divide the final number by (1 + growth rate)^time. For estimating the number of bacteria in the food 4 hours after contamination, multiply the initial number by (1 + growth rate)^time.

Explanation:

To find the initial number of bacteria X introduced into the egg salad, we can use the formula:

Initial Number = Final Number / (1 + Growth Rate)^Time

Plugging in the given values, we have:

Initial Number = 35,000 / (1 + 180%)^3 = 35,000 / (1 + 1.8)^3 = 35,000 / 3.027 = 11,542.52

To estimate the number of bacteria in the food 4 hours after contamination, we can use the same formula:

Number after 4 hours = Initial Number * (1 + Growth Rate)^Time

Plugging in the values, we have:

Number after 4 hours = 11,542.52 * (1 + 180%)^4 = 11,542.52 * (1 + 1.8)^4 = 11,542.52 * 10.4044 = 120,108.83

Which equation can be used to find how many days it will take David, Karen, and Rick to read 10,000 pages, together, by the end of summer?

Answers

David reads 80 pages every day.

Karen reads 25% more pages every day than David reads.

So, Karen reads [tex]\frac{25}{100}*80= 20[/tex] more pages. She reads a total of 80 + 20 =100 pages.

Rick reads 35% fewer pages per day than Karen. So, Rick reads [tex]\frac{35}{100}*100=35[/tex] less pages than Karen. He reads 100 - 35 =65 pages

So, in total the tree friends read = 80+100+65=245 pages.

Step-by-step explanation:

The total time for the student's total trip is A = 58 minutes

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is = total time for the trip

Substituting the values in the equation , we get

The total length of the bus route is 57 minutes. The student is taking a trip for 2/3 of the total route length, which is (2/3) x 57 = 38 minutes

In addition to the time on the bus, the student must also walk 10 minutes to get to the bus and 10 minutes from the bus to his destination.

Therefore, the total time for the student's trip is:

38 minutes (on the bus) + 10 minutes (walking to the bus) + 10 minutes (walking from the bus) = 58 minutes

Hence , the time for student's trip is A = 58 minutes

The bases of a trapezoid are 4 yards and 6 yards. The height of the trapezoid is 5 yards. What is the area of the trapezoid?

Answers

Final answer:

The area of a trapezoid with bases of 4 yards and 6 yards, and a height of 5 yards is calculated using the formula (1/2)*height*(sum of the bases). By substituting the given measurements, the area comes out to be 25 square yards.

Explanation:

The area of a trapezoid can be calculated using the formula: Area = ½×(height)×(sum of the bases). Given the measurements of a trapezoid with bases of 4 yards and 6 yards, and a height of 5 yards, we apply the formula:

Area = ½×(5 yards)×(4 yards + 6 yards)

First, sum the lengths of the bases:

4 yards + 6 yards = 10 yards

Then, substitute the sum of the bases and the height into the formula:

Area = ½×(5 yards)×(10 yards)

Area = ½×(50 yards²)

Area = 25 yards²

Therefore, the area of the trapezoid is 25 square yards.

My sister’s birthday is in a few weeks and I would like to buy her a new vase to keep fresh flowers in her house. She often forgets to water her flowers and needs a vase that holds a lot of water. In a catalog, there are three vases available and I want to purchase the one that holds the most water. The first vase is a cylinder with diameter 10 cm and height 40 cm. The second vase is a cone with base diameter 16 cm and height 45 cm. The third vase is a sphere with a diameter of 18 cm.

1. Find the volume for each vase.

2. Which vase should I purchase?

3. How much more water does the largest vase hold than the smallest vase?

4. Suppose the diameter of each vase decreases by 2 cm. Which vase would hold the most water?

Answers

Answer:

1. 392, 20.83, 4/3

2. 16 cm and 45 cm cone

3. 0.9 Fl oz

4. the cone still

Step-by-step explanation:

The volume of each vase can be determine by using volume formula of sphere, cone and cylinder.

(1) The volume of sphere is [tex]972\pi[/tex], volume of cone is [tex]960\pi[/tex] and volume of cylinder is [tex]1000\pi[/tex].

(2) You should purchase the cylinder vase.

(3) The largest vase hold [tex]40 \pi \:{\rm cm}^3[/tex] more than smallest vase.

(4) If the diameter decreases by 2 cm, then cone holds more water.

Given:

Diameter of cylinder is [tex]d=10 \:\rm cm[/tex].

Height of cylinder is [tex]h=40\:\rm cm[/tex].

Diameter of cone is [tex]d=16 \:\rm cm[/tex].

Height of cylinder is [tex]h=45\:\rm cm[/tex].

Diameter of sphere is [tex]d=45 \:\rm cm[/tex].

(1)

Calculate the volume of cylinder.

[tex]\begin{aligned}\mbox{Cylinder Volume} &= \pi r^2 h\\& = \pi(5)^2(40) \text{ cm}^3\\&= 1000 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of Cone.

[tex]\begin{aligned}\mbox{Cone Volume} &= \frac13 \pi r^2 h\\&= \frac13 \pi(8)^2(45) \text{ cm}^3\\&= 960 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of sphere.

[tex]\begin{aligned}\mbox{Sphere Volume} &= \frac43 \pi r^3\\&= \frac43 \pi (9)^3 \text{ cm}^3\\&= 972 \pi \text{ cm}^3.\end{align}[/tex]

(2)

Since the volume of cylinder is higher than the volume of sphere and cone. So, you should purchase cylinder vase.

(3)

The largest vase hold water more than the smallest vase is,

[tex]\text{Cylinder Volume} - \text{Cone Volume} = 1000 \pi \text{ cm}^3 - 960 \pi \text{ cm}^3 = 40 \pi \text{ cm}^3[/tex]

(4)

As per the question if diameter of each vase decreases by 2 cm then radius decreases by 1 cm.

Calculate the volume of cylinder.

[tex]\begin{aligned}\mbox{Cylinder Volume} &= \pi r^2 h\\&= \pi(4)^2(40) \text{ cm}^3\\&= 640 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of Cone.

[tex]\begin{aligned}\mbox{Cone Volume}&= \frac13 \pi r^2 h\\&= \frac13 \pi(7)^2(45) \text{ cm}^3\\&= 735 \pi \text{ cm}^3.\end{align}[/tex]

Calculate the volume of sphere.

[tex]\begin{aligned}\mbox{Sphere volume} &= \frac43 \pi r^3\\&= \frac43 \pi (8)^3 \text{ cm}^3\\&= 682 \frac23 \pi \text{ cm}^3.\end{align}[/tex]

Since the volume of cone is more the sphere and cylinder. So cone hold most water.
