What is the final amount if 457 is decreased by 1% followed by a further 3% decrease? Give your answer rounded to 2 DP.

Answers

Answer 1

Answer:

438.86

Step-by-step explanation:

1. 457 x 0.99 = 452.43 - Decreased by 1%

2. We need to decrease 452.43 again but this time by 3% - 452.43 x 0.97

3. This gives us an answer of 438.8571

4. Finally we need to round this to 2DP, the 7 (438.8571) rounds up so the number to the left increases. This leaves an answer of 438.86

Hope this helps :D

The length of a football field is 300 feet (excluding the end zones). The diagonal is about 316.2 feet. What is the width of the football field, rounded to the nearest foot?

Answers

Answer:

w = 100 ft

Step-by-step explanation:

A football fields is of rectangular shape, and for that shape, we know the length (300 ft) and one diagonal (316,2 ft). To determine the width we have to understand that diagonal, length and a width form a right triangle, and in a right triangle we can apply Pytagoras theorem. Therefore:

d(diagonal)²  =  l²  +  w²    where l is the length and w the width

d²  =  l² + w²    ⇒    d²  -  l²  = w²

w²  =  ( 316,2)² - (300)²   ⇒   w²  =  99982,44 - 90000

w² = 9982,44

w = √9982,44

w = 99,91 ft

Rounded to the nearest foot

w = 100 ft

3c+5=23

Answers

Answer: c = 6

To solve for c in the equation you see here,

our goal is to get c by itself.

Our first step will be to isolate the term

containing c which in this problem is 3c.

To isolate 3c, we have to get rid of the +5 by

subtracting 5 from both sides of the equation.

On the left, the +5 and -5 cancel out

and we are simply left with 3c.

On the right, 23 - 5 simplifies to 18.

Now we have 3c = 18.

To get c by itself, since it's being multiplied by 3,

we just divide both sides of the equation by 3.

On the left, the 3's cancel and we are left with c.

On the right, 18/3 simplifies to 6.

So our answer is c = 6.

Jared is going to plant 20 small plants around the edge of a circular garden
that is 8 feet in diameter. If he spaces the plants evenly, how much distance
will be between the plants? (Round to the nearest hundredth)
Blank 1:

Answers

Answer:

1 every 2.5 feet

Step-by-step explanation:

20 divided by 8 20 being the plants 8 being the length gives u 2.5

Rounding to the nearest hundredth, the distance between each plant will be approximately 1.26 feet.

To find the distance between each plant when they are evenly spaced around the edge of the circular garden, we can use the formula for the circumference of a circle:

[tex]Circumference (C) = \pi * diameter[/tex]

Rounding to the nearest hundredth, the distance between each plant will be approximately 1.26 feet.

Given that the diameter of the circular garden is 8 feet, we can calculate the circumference:

[tex]C = \pi * 8[/tex]

Now, let's calculate the circumference:

[tex]C = \pi * 8[/tex]

[tex]C = 3.14 * 8[/tex]

[tex]C = 25.12 feet[/tex]

Now, since there are 20 plants evenly spaced around the circumference, we can divide the circumference by 20 to find the distance between each plant:

[tex]Distance between plants = Circumference / Number of plants[/tex]

[tex]Distance between plants =25.12 / 20[/tex]

[tex]Distance between plants = 1.256 feet[/tex]

Complete correct question:

In 1970, the population of a small town was 4,200. The population is decreasing at a rate of 2.4% per year. Which of the following shows an exponential decay function to find the quarterly decay rate?The population is decreasing by how much percent per quarter?

Answers

Answer:

a. y = 4,200 [tex]0.976^{4t}[/tex]

b. 9.2%

Step-by-step explanation:

Given the information:

The intinital value: 4,200 The population is decreasing at a rate of 2.4% per year

=> the base number of the exponential function is:

100% - 2.4% = 97.6% = 0.976

Let t is quarter

Let y is the population

=>  the following shows an exponential decay function to find the quarterly decay rate is:

y (t)= 4,200 [tex]0.976^{4t}[/tex]

b. The population is decreasing by how much percent per quarter?

Let t = 0 we have: y(0) = 4,200 [tex]0.976^{4*0} = 4200[/tex]

Let t = 1 we have:  y(1) = 4,200 [tex]0.976^{4*1} = 3811[/tex]

=> the decreasing percentage is:

= (y(0) - y(1)) / y(0)*100%

= (4200 - 3811) / 4200 *100%

= 389/4200*100%

= 9.2%

The expoenetial function that represents the quarterly decay is y = 4200(0.994)^4t.

The  population is decreasing by 0.4% every quarter.

What is the exponential function that determines the rate of decrease every quarter?

The formula that can be used to determine the rate of decrease every quarter is:

FV = P(1 - r/m)^tm

FV = Future value P = Present value of the population = 4,200R = rate of decrease = 2.4%m = number of compoundingt = number of years

y = 4200( 1 - 0.024/4)^4t

y = 4200(1 - 0.006)^4t

y = 4200(0.994)^4t

A worker at a mill is loading 5 pound bags of flour into boxes to deliver to a local warehouse. Each box holds 16 bags of flour. If the warehouse orders 4 tons of flour how many boxes are needed to fulfill the order ?

Answers

Answer:

100 boxes are needed to fulfill the order

Step-by-step explanation:

In this question, we are concerned with calculating the number of boxes that are needed to fulfill an order.

Each of the boxes contain 16 bags of flour and each of these bags weigh 5 pounds. What this means is that each of the boxes will have a net weight of 5 * 16 = 80 pounds

Mathematically, 1 ton is the equivalent of 2,000 pounds. Hence, 4 tons is the equivalent of 4 * 2000 = 8,000 pounds

Thus, the number of boxes needed will be 8,000/80 = 100 boxes

The linear parent function, f(x) = x, is transformed to g(x) = 2x + 7. Which
statement correctly compares the graphs of the functions?

Answers

Final answer:

The graph of g(x) = 2x + 7 is a vertical shift of the graph of f(x) = x by 7 units upward.

Explanation:

The linear parent function, f(x) = x, is transformed to g(x) = 2x + 7. The transformation is a vertical shift of 7 units upward and a horizontal stretch by a factor of 2. To compare the graphs of the functions, we can plot a few points and observe the differences. For example, if we consider x = 0, for the parent function f(x) = x, the output is f(0) = 0. However, for the transformed function g(x) = 2x + 7, the output is g(0) = 7. This shows that all the y-values of the transformed function are 7 units higher than the corresponding y-values of the parent function. Therefore, the statement that correctly compares the graphs of the functions is that the graph of g(x) is a vertical shift of the graph of f(x) by 7 units upward.

https://brainly.com/question/35061121

#SPJ12

Final answer:

The function g(x) = 2x + 7 has a steeper graph than f(x) = x due to a larger slope and is also shifted upward by 7 units.

Explanation:

The linear parent function f(x) = x is transformed to g(x) = 2x + 7. When comparing the graphs of the two functions, we notice that g(x) is a transformed version of f(x). Specifically, the graph of g(x) has a slope of 2, which is a steeper incline than the parent function f(x), which has a slope of 1. Additionally, g(x) has a vertical shift upwards by 7 units. Therefore, the statement that correctly compares the two graphs would indicate that g(x) is steeper and shifted 7 units up from the graph of f(x).

Lana is creating a video.Her computer shoes that the video is 184.026 second long. She writes the length of the video in expanded form. Which expression represents the value of one of the digits in the length of Lana video

Answers

Answer: 6 × 1/1000

Step-by-step explanation:

Lana is creating a video. Her computer shoes that the video is 184.026 second long. From the figures, 184.026

1 represents 100

8 represents 80

4 represents 4

0 represents 0 tenths

2 represents 2 hundredths

6 represents 6 thousandths

Therefore, 6 × 1/1000 is the right answer.

The correct expanded form expression for one of the digits in Lana's video length is D. 6 * [tex]\frac{1}{1000}[/tex] which matches the digit 6 in the thousandths place correctly.

Lana's video length is 184.026 seconds. To write it in extended form, we separate each digit by its place value:

1 * 1008 * 104 * 10 * [tex]\frac{1}{10}[/tex]2 * [tex]\frac{1}{100}[/tex]6 * [tex]\frac{1}{1000}[/tex]

Now, let's match the given options to this expanded form:

A. 1 * 1000: This is incorrect because 1 is multiplied by 100, not 1000.B. 2 * [tex]\frac{1}{10}[/tex] : This is incorrect because 2 is multiplied by [tex]\frac{1}{100}[/tex]C. 4 * 10: This is incorrect because 4 is multiplied by 1.D. 6 * [tex]\frac{1}{1000}[/tex] : This is correct because 6 is indeed multiplied by 1/1000.

Therefore, the correct answer is D. 6 * [tex]\frac{1}{1000}[/tex]

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 5) and (8, 1280)

Answers

Answer:

[tex] a =5[/tex]

Now we can use the info from the second point and we have:

[tex] 1280 = 5 b^8 [/tex]

We can divide 5 in both sides and we got:

[tex] 256 = b^8[/tex]

And using an exponent 1/8 in both sides we got:

[tex] (256)^{1/8} = b[/tex]

[tex] b = 2[/tex]

And then our model would be given:

[tex] y= 5 (2)^x [/tex]

Step-by-step explanation:

For this case we have two points given (0,5) and (8,1280). And we want to find a function given by this general expression:

[tex] y= ab^x [/tex]

And using the first point given we have:

[tex] 5 = a b^0 [/tex]

[tex] a =5[/tex]

Now we can use the info from the second point and we have:

[tex] 1280 = 5 b^8 [/tex]

We can divide 5 in both sides and we got:

[tex] 256 = b^8[/tex]

And using an exponent 1/8 in both sides we got:

[tex] (256)^{1/8} = b[/tex]

[tex] b = 2[/tex]

And then our model would be given:

[tex] y= 5 (2)^x [/tex]

Final answer:

To write an exponential function that passes through (0, 5) and (8, 1280), we first use the point (0, 5) to find that a = 5. Then, using the point (8, 1280), we solve for b, finding b = 2. Thus, the required exponential function is[tex]y = 5.2^x.[/tex]

Explanation:

To write an exponential function in the form y=ab^x that goes through the points (0, 5) and (8, 1280), we need to solve for a and b.

Step 1: Use the First Point (0, 5)

Substitute x = 0 and y = 5 into the equation:
5 = a · [tex]b^0[/tex]
Since any number raised to the power of 0 is 1, we find:
a = 5

Step 2: Use the Second Point (8, 1280)

Substitute x = 8, y = 1280, and a = 5 into the equation:
1280 = 5 ·[tex]b^8[/tex]
To solve for b, divide both sides by 5:
256 = [tex]b^8[/tex]

Finding the 8th root of both sides gives:
b = 2

Step 3: Write the Exponential Function

Now that we have a = 5 and b = 2, the exponential function is:
y = 5·[tex]2^x[/tex]
