Complete Question

Carmen and Matt are conducting different chemistry experiments in school. In both experiments, each student starts with an initial amount of water in a flask. They combine two chemicals which react to produce more water. Carmen's experiment starts with 30 milliliters of water in a flask, and the water increases in volume by 8.5 milliliters per second. Matt's experiment starts with 10 milliliters of water and increases in volume by 28% each second. The graph represents the volume of water in the two flasks in relation to time. Which two conclusions can be made if f represents the volume of water in Carmen's flask and g represents the volume of water in Matt's flask? a) The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [0, 2].

b) The volume of water in Carmen's flask is increasing at a faster rate than the volume of water in Matt's flask over the interval [6, 8].

c) The volume of water in Carmen's flask will always be greater than the volume of water in Matt's flask.

d) The volume of water in Matt's flask will eventually be greater than the volume of water in Carmen's flask.

e) The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [4, 6].

Answer:

c) The volume of water in Carmen's flask will always be greater than the volume of water in Matt's flask.

e) The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [4, 6].

Step-by-step explanation:

Looking at the graph, the average rate of change is given as [0,2], [4,6], and [6,8].

From the graph and question, we can tell that Matt's experiment starts with 10 milliliters of water and increases in volume by 28% each second

Which would gives us:

28% of 10 milliliter of water = 2.8 millimeters per second.

For Carmen , his experiment starts with 30 milliliters of water in a flask, and the water increases in volume by 8.5 milliliters per second,

Because, Carmen starts with 30 milliliters of water in his flask, the volume of water in Carmen's flask will always be greater than the volume of water in Matt's flask.

Secondly, comparing the quantity as which the volume of the flask increases per second, at the interval of [4, 6], the volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval

Anna made an error in determining the polynomial equation of smallest degree whose roots are -4,-2, -
nalin [4]

Answer:

See explanation

Step-by-step explanation:

Ana started the work nicely by multiplying out factors to get:\

(x+4)(x+2)(2x+1)(x-2)=0

She multiplied (x+2)(x-2) correctly using difference of two squares to get: x^2-4

Unfortunately: She made a mistake in multiplying (x+4)(2x+1) she mistakenly got x^2+9x+4 instead of 2x^2+9x+4. <em>She left out the coefficient of 2.</em>

Therefore the second step should have been:

(x^2-4)(2x^2+9x+4)

The next step will now be:

2x^4+9x^3+4x^2-8x^4-36x-16=0

This simplifies to

2x^4+9x^3-x^4-36x-16=0

Really confused on this and need some help to figure this out (i'll give a brainliest to whoever will help)
inna [77]

Answer:

55

Step-by-step explanation:

The angles are complementary as they add up to make a right angle/ 90° as indicated by the small square. So let's make an equation and solve for x :

x-20 + x = 90

Add 20 to both sides :

x+x = 110

2x = 110

Divide both sides by 2 :

x = 55

Hope this helped and have a good day

Circle towns limit form a perfectly circular shape that has a population of 20000 in the population density of 480 people per sq
Alex

Answer:

D =\frac{P}{\pi X^2}

And solving for the radius we got:

X = \sqrt{\frac{P}{\pi D}}

And replacing the data given we got:

X = \sqrt{\frac{480 \frac{people}{km^2}}{\pi *20000 people}}= 0.0874Km

And this value converted to meters is X = 87.40 m

Step-by-step explanation:

For this case we know the population size P = 20000 and we also know the population density D = 480 \frac{people}{km^2}

We can assume that the area is a circle. We also know that the formula for the population density is given by:

D= \frac{P}{A}

Where P represent the number of people and A the area. Since we are assuming a circle then the area is given by:

A = \pi X^2

With X the radius of the circle

And then the populationd density become:

D =\frac{P}{\pi X^2}

And solving for the radius we got:

X = \sqrt{\frac{P}{\pi D}}

And replacing the data given we got:

X = \sqrt{\frac{480 \frac{people}{km^2}}{\pi *20000 people}}= 0.0874Km

And this value converted to meters is X = 87.40 m

You move left 4 units and right 2 units. You end at (8, 8). Where did you start?
dangina [55]

Answer:

(10,8)

Step-by-step explanation:

You actually only move 2 left since 2 left and 2 right cancel out. So, you add 2 to the x value to find 10.
