What is the slope of a line that passes through the points (2, 0) and (5, 0)? Explain.incorrect answer: 0; The change in \(x\) is 0 because the x-values do not change. So, the slope is 0.a) 0; The change in y is 0 because the y-values do not change. So, the slope is 0.b) undefined; The change in x is 0 because the x-values do not change. So, the slope is undefined. c) undefined; The change in y is 0 because the y-values do not change. So, the slope is undefined.d) 2/5; To find slope, divide the x-value of the first point by the x-value of the second point. So, the slope is 2/5.e) 5/2; To find slope, divide the x-value of the second point by the x-value of the first point. So, the slope is 5/2.

A Wooden board is leaning against the house the base of the board is 10 feet from the base of the house and the base of the board forms a 35° angle with the ground what is the length of the wooden board

Answers

Answer: 12.20 feet.

Step-by-step explanation:

Observe in the figure attached that a right triangle is formed.

Then, you  need to remember the identity:

cos\alpha=(adjacent)/(hypotenuse)

In this case you can identify that:

adjacent=10\nhypotenuse=x

\alpha=35\°

Then, to find the length of the wooden board (x), you need to substitute values and solve for x.

Therefore, you get:

cos(35\°)=(10)/(x)\n\n(x)(cos(35\°))=10\n\nx=(10)/(cos(35\°))\n\nx=12.20

The length of the wooden board is: 12.20 feet.

Twelve boys collected 16 aluminum cans each. Fifteen girls collected 14 aluminum cans each. How many more cans did the girls collect than boys?

Answers

The girls collected 18 more cans.

you need to find the total cans collected by boys and girls. To do this you multiply 16 and 12 for the guys cans and 15 and 14 for the girls cans.

Once you have your products you subtract them and you'll get 18 :)
The girls collected 18 more than the boys

What fraction of a mile is each landmark from the exit? Zoo 0.8 miles Camping 0.5 miles Hotels 0.2 miles

Answers

You can convert decimals into fractions by understanding how a decimal already is a fraction.  Let's take the location of the zoo from the exit.  It's 0.8 miles from the exit, right?  Just add a "0" to the end of the "0.8", so you have "0.80".  "0.80" is also written as 80 out of 100, which is also written as 80/100.  Now, you can simplify this like a normal fraction and get 8/10.  The same applies for the other two locations.  The Campsite is 0.5 miles from the exit, or 0.50, or 50/100, and then 5/10, and even further to 1/2.  This is because 5 is half of ten.  The Hotel is 0.2 miles from the exit, which is 0.20 miles, aka 20/100, which can then be simplified to 2/10 and then 1/5, because 2 is a fifth of ten.

I hope I helped!  And if you have any questions or don't understand what I wrote, feel free to contact me about it.  :D  Have a great day!
First see how many digits are in the decimal. 0.8 has 2 digits, so it's a 10. My denominator is 10. My last digit is 8, so my numerator is 8. 8/10 is my answer. Convert 0.5 to 5/10 and 0.2 to 2/10. Just use the same rules for all the answers. Also, if you had for example 0.09 then your answer will be 9/100. Also, another example is if you had 0.030 then your answer will be 30/1000.

Hope that helped:)

My cousin was interested in reactions that produce carbon dioxide gas. She wondered if there was some way to predict how much gas a reaction would produce. She did a series of seven experiments and measured the amount of carbon dioxide released by each one. Baking soda (spoons) Calcium chloride (spoons) Carbon dioxide (milliliters) 1 1 800 1 2 1600 1 3 1600 2 1 800 2 2 1600 2 3 2400 3 1 800 Based on my cousin’s experimental results,answer these questions. 1. How many mL of gas would be produced if 3 spoons of baking soda reacted with 3 spoons of calcium chloride? 2. How many mL of gas would be produced if 2 spoons of baking soda reacted with 1.5 spoons of calcium chloride? 3. My cousin wanted to produce exactly 2000 mL of carbon dioxide. How much baking soda and calcium chloride should she use?

Answers

Answer:

1.)2240

2.)1173.33334

3) soda = 3, calcium chloride = 2.625

Step-by-step explanation:

Baking soda (spoons)

1 - 1 - 1 - 2 - 2 -2 - 3

Calcium chloride (spoons)

1 - 2 - 3 - 1 - 2 - 3 - 1

Carbon dioxide (milliliters)

800 - 1600 - 1600 - 800 - 1600 - 2400 - 800

Modeling the above using a multiple regression technique:

ŷ = ax1 + bx2 + c

Where ŷ is the predicted value

x1 and x2 are the first and second predictor variable.

ŷ = 106.66667X1 + 640X2 - 0

1.) How many mL of gas would be produced if 3 spoons of baking soda reacted with 3 spoons of calcium chloride?

ŷ = 106.66667(3)+ 640(3) - 0

320.00001 + 1920 - 0 = 2240

2.) How many mL of gas would be produced if 2 spoons of baking soda reacted with 1.5 spoons of calcium chloride?

ŷ = 106.66667(2)+ 640(1.5) - 0

213.33334 + 960 + 0 = 1173.33334

C.) To produce 2000mL of gas

It could be achieves a a number of ways

ŷ = 106.66667X1 + 640X2 - 0

For instance if she opts to use 3 spoons of soda

2000 = 106.66667(3) + 640x2

2000 = 320.00001 + 640x2

2000 - 320 = 640x2

x2 = 1680/640

x2 = 2.625 spoons

Below are two different function, f(x) and g(x). what can be determined about their slopes?

Answers

Answer:

F(x) has a larger slope.

Step-by-step explanation:

f(x) has a slope of 10 and g(x) has a slope of 9. The slope of f(x) can be found by dividing 800 by 80 (800 / 80 = 10). The slope of g(x) can be found by using the rate of change formula: y2 - y1 / x2 - x1. Choose two of the points from the chart. I'll use (2, -6) and (4, 12). Plug in the numbers so the equation would be 12-(-6) / 4-2. This simplifies to 18 / 2 which is 9.
