The correct answer is option B which is the pool must have been the same depth at the start of the interval as it was at the end of the interval.

The rate of change is defined as the changes that occur in any data with respect to time like changing of level of water respect to time. Changing of the position of any object with respect to time that is speed.

Here in the question, it is given that Lionel computed the average rate of change in the depth of a pool over a two-week interval to be zero. The meaning of this statement is that the level of the water in the pool is the same as that of the level two weeks ago.

Therefore the correct answer is option B which is the pool must have been the same depth at the start of the interval as it was at the end of the interval.

The actual weight of the mobile in grams is 194 grams.

In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

As broken scale shows a false weight that is always higher than the actual weight by the same number of grams.

When a mobile phone is put on the scale, the real weight will be  'x'

but it shows,

x+a= 202

When an headphone is put on the scale, the real weight will be  'y'

but it shows,

y+a=221

When the mobile phone and the headphone are put on the scale together, the weight is

x+y+a= 415

So,

x+221=415   [Since y+a= 221 grams]

x= 194 grams

The actual weight of the mobile phone in grams is 194 grams.

X= -4x-4=-4(x+2)

X=-4x-4=-4x-8

X=-4x+4x=-8+4

X=-4

Answer:

so there is no x but it looks like it is undefined

Step-by-step explanation:

-4x - 4 = -4(x+2)  1. multiply -4 with x and 2

-4x - 4 = -4x - 8   2. + 4 on both sides

-4x = -4x - 4         3. +4x on both sides

Answer:

B

Step-by-step explanation:

essentially the plan that increases the price the most per week reaches the goal of $12 fastest.

plan A is $0.10 per week.

plan B it is not clear, if it means 10% of the original price every week, or every week 10% of the price of the previous week. I assume the first and simplest.

that means 10% of $8 = $0.80 per week.

plan C : the same amount every week until reaching $12. we need to increase in total by $4 (from $8 to $12). to reach these $4 in 8 weeks, we need to increase the price every week by 4/8 = $0.50.

plan D : $0.25 per week.

so, the plan with the highest increase every week and therefore the fastest one reaching $12 is plan B.

x(adjucent ) = 3.8

Step-by-step explanation:

okay so you are been giving me a left angle triangle so what you are supposed to do is that the longest part which is indicated 7.4 is called the hypothesis whiles the other side indicated 3.6 is called the opposite and the down part is the adjacent. so to find the adjacent your formula is opposite + adjacent = hypothesis .

so therefore we can see that

3.6 + x = 7.4

x = 7.4 - 3.6

x = 3.8

Answer:

[tex]3^{n}+3^{n-1}[/tex]

Step-by-step explanation:

Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be [tex]x^n + yn[/tex]

Because the sequence multiplies by 3 each time, The base number in that equation would be [tex]3^n +yn[/tex].

So [tex]3^n[/tex] of the equation would be:
[tex]3, 9, 27[/tex].

Compare the 2 equations:
4, 12, 36

3, 9 ,27

The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is: [tex]3^{n-1}[/tex].

Combine these 2 equations together and you get:

[tex]3^{n}+3^{n-1}[/tex].

Amount earned per week=400-380=$20

Price of one shoe=70$

Total weeks

Minimum 4 weeks

Answer:

4 weeks

Step-by-step explanation:

Given:

Therefore,

Weekly surplus = weekly net income - weekly expenses

                          = $400 - $380

                          = $20

Given:

Number of weeks = cost of new shoes ÷ weekly surplus

                              = $70 ÷ $20

                              = 3.5

                              = 4 weeks (rounded to nearest week)

Therefore, it will take 4 weeks to save enough to buy the shoes.

The fractional expression 18/48 is greater than 14/48 or 6/16 is greater than 7/24. Then the correct option is A.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The expressions are 6/16 and 7/24.

Then the LCM of the 16 and 24 will be 48.

Then the expressions will be 18/48 and 14/48.

The fractional expression 18/48 is greater than 14/48 or 6/16 is greater than 7/24.

Thus, the correct option is A.

Mean = 1.8 in

Step-by-step explanation:

The Median is the middle value when all data values are placed in order of size.

Ordered data values:  0, 0, 0, 1, 1, 1, 2, 3, 4, 6

As there is an even number of data values, the middle value is the mean of the middle two data values.  Therefore, the Median = 1 in

The Mean is the sum of all data values divided by the total number of data values.

[tex]\implies \textsf{Mean}=\dfrac{0+0+0+1+1+1+2+3+4+6}{10}=1.8[/tex]

Therefore, the Mean = 1.8 in

The Median is a better measure of central tendency when the data includes outliers (data values that are far away from the majority), as it is not affected by those outliers.  As there does not appear to be any outliers in this data set, the mean can be used to best describe the center of the data.

Therefore, the Mean = 1.8 in

Step-by-step explanation:

The given triangle is a right triangle.  Therefore, we can use Pythagoras Theorem to find the measure of the third side.

Pythagoras Theorem

  [tex]a^2+b^2=c^2[/tex]

where:

From inspection of the given triangle:

To calculate the measure of the third side "b", substitute the given values into the formula and solve for b:

[tex]\begin{aligned}a^2+b^2 & = c^2\\\implies 4^2+b^2 & = 13^2\\16+b^2 & = 169\\16+b^2-16 & = 169-16 \\b^2 & = 153\\\sqrt{b^2} & =\sqrt{153}\\b & = \sqrt{9 \cdot 17}\\b & = \sqrt{9}\sqrt{17}\\b & = 3\sqrt{17}\end{aligned}[/tex]

Therefore, the measure of the third side of the given right triangle in simplest radical form is  [tex]3 \sqrt{17}[/tex].
