Answers

Answer 1

Answer: The fan catch the ball after 3 seconds.

Step-by-step explanation:

Given,  A baseball 4 feet off the ground is hit with an upward velocity of 52 feet per second.

The height of the baseball in feet after t seconds is given by the equation

[tex]h = - 16t2 + 52t + 4[/tex]

If a fan catches the ball 16 feet off the ground when it is coming  down.

then, at that time h= 16  feet

At h= 16

[tex]16=-16t^2+52t+4\\\\\Rightarrow\ 16t^2-52t+12=0\\\\\Rightarrow\ 4t^2-13t+3=0[/tex]

[tex]\Rightarrow\ 4t^2-t-12t+3=0\Rightarrow\ t(4t-1)-3(4t-1)=0\\\\\Rightarrow\ (4t-1)(t-3)=0\\\\\Rightarrow\ t=\dfrac{1}{4},\ t=3[/tex]

From the graph , it can be observe that when ball comes back , for height 16 feet the corresponding time t= 3 sec

So, the fan catch the ball after 3 seconds.

PLEASEE HEEELP! In the normal distribution, 68% of the data lies within 1 standard deviation A: __/6 of the mean, 95% of the data lies within 2 standard deviations of the mean, and 99.7% of the data lies within 3 standard deviations of the mean. Answer the following question without using the Z-table. If scores on a test are normally distributed with mean 1100 and standard deviation 100, what percentage of the test scores are: a) more than 1300? b) less than 1100?

Answers

Answer:

a) 2.5% b) 50%

Step-by-step explanation:

1300 is two standard deviations higher than the mean. Since 95% of the data is covered within two standard deviations to the left and right of the mean, 5% is not covered. So, we have 2.5% leftover on the left side of the curve, under 900, and 2.5% leftover on the right side of the graph that is above 1300.

The mean is 1100, so anything above or below the mean is exactly 50% in a normal distribution.

Answer:

Step-by-step explanation:

This is the Empirical Rule.

68% of the data lies within 1 standard deviation of the mean, and so on.

If the mean is 1100 and the standard deviation is 100, 1300 represents two standard deviations above the mean.  Using a calculator with distribution functions, we type in normcdf(2,10000), obtaining 0.023.  This tells us that 2.3 percent of test scores are more than 1300.

Less than 1100:  Since the mean is 1100, the area under the standard normal curve is exactly 0.5 (corresponding to 50% of data are less than 1100).

On the graph of an exponential function representing growth what happens to the slope of the graph as X increases

Answers

Answer:

The slope of the graph will increase and get steeper.

Step-by-step explanation:

As x increases in an exponential growth graph, f(x) will have a larger value because the exponent value increases.

So, the graph will become steeper due to a larger slope.

The slope of the graph will increase and get steeper.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,m = Δy/Δx where, m is the slope

Given:

As we know that, all points on an exponential curve are always at a constant distance from one another because the slope of an exponential curve equals the constant rate of expansion.

The graph is not exponential if the slope is not constant.

So, In an exponential growth graph, f(x) will have a greater value as x grows as the exponent grows.

Consequently, a larger slope will cause the graph to grow steeper.

Where m is the slope of the line and c is the y-intercept of the line.

A cab driver charges a level pace of $3.50 in addition to an extra $1.65 per mile.

Let 'y' be the total amount and 'x' be the number of miles. Then we have

y = 3.50x + 1.65

If Mohammad wants to spend, at most $60. Then the number of miles is given as,

60 = 3.50x + 1.65

3.50x = 58.35

Answer: 288 cm^3

Explanation:

Volume of on bar = 8*3*1 = 24 cm^3

Volume of 12 bars = 8*3*1*12 = 24*12 = 288 cm^3


Hope it helps ya

Answer:

288 cm^3

Step-by-step explanation:

First, you have to calculate the volume of your individual bar. To do this, you multiply the three given values, so it would look like 8*3*1=24. This means that your individual bar has a volume of 24 cm^3.

To hold 12 granola bars, this would mean that your volume of the individual granola bar would be multiplied by 12, because that is how many you want to fit inside the box. So your operation would looked like 24*12=288 cm^3

Step-by-step explanation:

Let the initial amount of money Ami, Jan and Toy have initially be A, J and T respectively.

Please see attached picture for full solution.

Answer:

$252

Step-by-step explanation:

Step 1

Toy has $36 and gets $36 from Ami. Now he has $36*2= $72

Step 2

Toy gets $72 from Jan to double his money and now has $72*2= $144

Step 3

Toy gives enough money to Ami and Jan to double their money

Toy has $36 at the end, so he has given $144 - $36= $108 to Ami and Jan

Since he doubles their money by giving $108, they now have

$108*2= $216

Now we add the amount Toy has at the end to the amount Ami and Jan have at the end to get final amount:

$216+$36= $252So the friends have $252

These United States are confronted with an economic affliction of great proportions. We suffer from the longest and one of the worst sustained inflations in our national history. It distorts our economic decisions, penalizes thrift, and crushes the struggling young and the fixed-income elderly alike. It threatens to shatter the lives of millions of our people. Idle industries have cast workers into unemployment, human misery, and personal indignity. Those who do work are denied a fair return for their labor by a tax system which penalizes successful achievement and keeps us from maintaining full productivity. In this present crisis, government is not the solution to our problem, government is the problem. What is one way that President Reagan addressed the "crisis? He began the War on Drugs. He reduced regulations on businesses He called for a stronger national defense. He appointed three Supreme Court justices.

Sketch the graphs:y=-x+5 Read the excerpt from President Ronald Reagans Address at Moscow State University.The explorers of the modern era are the entrepreneurs, men with vision, with the courage to take risks and faith enough to brave the unknown. These entrepreneurs and their small enterprises are responsible for almost all the economic growth in the United States. They are the prime movers of the technological revolution. In fact, one of the largest personal computer firms in the United States was started by two college students, no older than you, in the garage behind their home. Some people, even in my own country, look at the riot of experiment that is the free market and see only waste. What of all the entrepreneurs that fail? Well, many do, particularly the successful ones; often several times. And if you ask them the secret of their success, they'll tell you it's all that they learned in their struggles along the way; yes, it's what they learned from failing. Like an athlete in competition or a scholar in pursuit of the truth, experience is the greatest teacher.Which is a substantiated opinion?One of the largest computer companies began in a garage.Small businesses are the reason America has a strong economy.Experience is the best way for entrepreneurs to learn.People are often wasteful in free market societies.

Variable expenses are $40.00 per unit, and fixed expenses total $200,000 per year. Its operating results for last year were as follows: Sales $ 2,080,000 Variable expenses 1,040,000 Contribution margin 1,040,000 Fixed expenses 200,000 Net operating income $ 840,000 The company president wants to add new features to the product, which will increase the variable expenses by $1.90 per unit. She thinks that the new features, combined with some increase in marketing spending, would increase this year's sales by 25%. How much could the president increase this year's fixed marketing expense and still earn the same $840,000 net operating income as last year Which two parts of this excerpt reflect Winston Churchill's belief that the Nazis could be overcome only through the collaboration of Great Britain and its alles
