Answer 1

Answer:

A student writes the inequality representing the graph as y ≥ –2(x – 10)2 + 200.

The inequality is

✔ incorrect

because testing the point (5, 100) simplifies to the inequality

✔ 100 ≥ 150

.

Step-by-step explanation:

A student writes the inequality representing the graph as y ≥ –2(x – 10)2 + 200.

The inequality is

✔ incorrect

because testing the point (5, 100) simplifies to the inequality

✔ 100 ≥ 150

.

Answer 2

The inequality is incorrect because testing the point (5, 100) simplifies to the inequality 100 ≥ 150.

What is an inequality?

An inequality can be defined as a mathematical relation that is typically used for comparing two (2) or more numerical data and variables in an equation based on any of the following arguments (symbols):

Greater than (>).Greater than or equal to (≥).Less than (<).Less than or equal to (≤).

Next, we would evaluate and simplify the given inequality in order to determine its solution as follows:

y ≥ –2(x – 10)² + 200.

At point (5, 100), we have:

100 ≥ –2(5 – 10)² + 200.

100 ≥ –2(-5)² + 200.

100 ≥ –2(25) + 200.

100 ≥ –50 + 200.

100 ≥ 150 (incorrect and false).

In conclusion, the given inequality is incorrect because 100 cannot be greater than or equal to 150.

Answers

The population that is most dense is the one for  5000 individuals per 200 square meters

Given the following information:

100 individuals per 100m^2

5000 individuals per200m^2

100,000 individuals per 20,000m^2

15,000 individuals per 10,000m^2

We find the population that is most dense using the formula:

Population density=(No. of people/Land area)

For 100 individuals per 100m^2,

Population density=100/100=1

For 5000 individuals per200m^2

Population density=5000/200=25

For 100,000 individuals per 20,000m^2

Population density=100,000/20,000=5

For 15,000 individuals per 10,000m^2

Population density=15,000/10,000=1.5

Hence, highest population density is 25 for 5000 individuals per200m^2

Answers

Not necessarily, because this was not an experiment.

In my opinion, Yet scientific evidence from case studies, surveys of meditator experiences, and historical studies is emerging to show that meditation can be associated with stress, negative effects, and mental health problems. Meditation can induce a state of deep relaxation and a calm mind. During meditation, you focus your attention and eliminate the stream of disorganized thoughts that can fill your mind and cause stress. This process can lead to increased physical and emotional well-being.

What is geometric sequence?

A geometric progression, also known as a geometric sequence, is a non-zero number sequence in which each term after the first is found by multiplying the previous one by a fixed, non-zero number known as the common ratio.

Number sequences are groups of numbers that adhere to a pattern or rule. A geometric sequence is one in which the rule is to multiply or divide by a specific number each time.

We have,

20, 10, 5, …

5 - 10 = -5

Since -10 ≠ -5, therefore the given series has no standard difference, which means the given sequence is not arithmetic.

Adam’s house is 12 miles from his house. It takes his older brother 20 minutes to drive him school. What is his brother’s driving speed

Answers

Step-by-step explanation:

I assume we want ca miles/hour answer as speed.

but just formally, any distance per time unit is speed.

in that sense

12 miles / 20 minutes = 3 miles / 5 minutes

is the speed.

but now to convert this to miles/hour.

we want to multiply 3/5 or 12/20 by f/f, so that the denominator is 1 hour.

by multiplying the numerator by the same value we make sure the speed ratio remains the same.

so, what "f" do we need to multiply 20 with to get 60 (1 hour = 60 minutes) ?

right, f = 3

therefore, we get

12/20 × 3/3 = (12×3)/(20×3) = 36/60 = 36 miles / 1 hour

his brother's driving speed was 36 miles/h or 36 mph.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

here, it is given that :

Estimated number of members in his bicycle club by the end of summer = 21

Actual number of members in his bicycle club by the end of summer = 15

Now, the percent error of Ming’s estimate :

percent error = {(21-15)/15 } x 100

percent error = (6/15) x 100

percent error = 40%

Therefore, the percent error of Ming’s estimate is 40%.

The first 4 terms are 3,9,15, and 21

Step-by-step explanation:

The first term in the recursive formula is 3 (it is important because that would be the number we substitute for the second term. This logic also applies to finding the next term with the answer to the previous term) The formula is an = a(n-1) + 6. Because of this formula the nth on the right side is the previous one plus 6. With that in mind let find the mext three terms To find a2 you would first substitute n for 2 making it a2 = a(2-1) +6 which is a2 = a1 + 6. We know that the first term is 3 so we substitute a1 for 3 to get a2 = 3 + 6 which is 9. The second term is 9 To find a3 we do the same steps for solving a2 only this time we use the second term to put in place of a2+ 6 which is 9 + 6 which equals to 15. The third term is 15 Again we are doing the same steps to find a4 but we use the third term to substitute for a3 + 6 which is 15 + 6 which equals to 21. The fourth term is 21.

Primarily use the Distributive Property to solve this equation.

3(5 - x) - 2(5 + x) = 3(x + 1)

Distribute the outer terms.

3(5) + 3(-x) - 2(5) - 2(x) = 3(x) + 3(1)
15 - 3x - 10 - 2x = 3x + 3
-3x - 2x + 15 - 10 = 3x + 3
-5x + 5 = 3x + 3

Now, isolate all x terms.

-5x + 5x + 5 = 3x + 5x + 3

What is proportional relationship?

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.

Given.

The proportion is: according to the first row of the proportional relationship

Solution:

To determine this from a graph, we should note that a function which is symmetrical with the y-axis is an even function. The graph which is symmetrical with the origin after a 180 degree rotation is an odd function.

Observe that if this graph is flipped from left to right (across the y-axis), it would not retain its original shape.

However, if the graph is rotated 180 degrees about the origin, it would retain its original shape.
