Answer:

3. 50

4. 1

Step-by-step explanation:

-5a + 2b - 6c

Substitute the variables, knowing that:

a = -6, b = 4, and c = -2

-5(-6) + 2(4) - 6(-2)

Multiply -5 and -6.

30 + 2(4) - 6(-2)

Multiply 2 and 4.

30 + 8 - 6(-2)

Multiply -6 and -2.

30 + 8 + 12

Add 30 and 8.

38 + 12

Add 38 and 12.

√(5x) + 2y

Substitute the variables, knowing that:

x = 5 and y = -2

√(5(5)) + 2(-2)

Multiply 5 and 5.

√(25) + 2(-2)

Multiply 2 and -2.

√(25) - 4

Take the square root of 25.

5 - 4

Subtract 4 from 5.

Answer:

ok when you first loaded the x y z fraction question on another page you asked for help where two people had answered saying it was 3 they were wrong the answer is 6 as 18/3 = 6 the answers below are for this question above hope this helps you also

Step-by-step explanation: QU 1 = 50 + QU 2 = 1

Qu 1) -5 a + 2b - 6c = rewrite out empty brackets for a and b and c Then step 2 is to input number's in brackets as a = -6 b = 4 and c = -2 we substitute so write out first (-5 ( )) + 2( ) - (6( )) if all polynomials are + - we show so like in bold then its easier to determine what to fill in to substitute (-5 (-6)) + 2(4) - (6(-2)) = 30 + 8 + 12 = 50 if we rewrote like this instead (-5 (-6)) + 2(4) -6(-2)) it would also be right so the answer is 50 Qu 2) sq rt 5x +2 y = (when x = 5 and y = -2) sq rt 5(5) and + 2(-2) = sq rt 25 -4 = 5 -4 = 1 Hope this helps also free worksheet info for graphs to explain things math.utah.edu/~wortman/1050-text-calp.pdf just type www in front helps all students that are struggling with graphs

The water level of a certain body of water is changing at a rate of W(t)=3/4cos(4-t/2) inches per hour, where t represents hours

Leni [432]

Answer:

The answer is below

Step-by-step explanation:

a) The integral $\int\limits^{10}_{1 } {W(t)} \, dt$ means the total change in level of water in inches from 1 am to 10 am. That is the water level change measured in inches between 1 am and 10 am

b) 7 pm is represented as t = 19 hours, while midnight is represented as t = 24 hours, hence the water level change between 7 pm and midnight is:

$\int\limits^{24}_{19 } {W(t)} \, dt\\\\$

c) Using casio calculator to evaluate the integral gives:

$\int\limits^{24}_{19 } {W(t)} \, dt\\\\$ = 2.54 inches

D) The total daily change in water level = $\int\limits^{24}_{0 } {W(t)} \, dt\\\\$ = 0.35 inches

Suppose an automobile manufacturer designed a radically new lightweight engine and wants to recommend the grade of gasoline that

Deffense [45]

Answer:

The F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.

Step-by-step explanation:

There are four treatments in the data given, i.e. k = 4.

Total number of observations, n = 12.

Note: degrees of freedom is denoted as df.

For treatment, the degrees of freedom = k-1 = 4-1 =3 df.

The total degrees of freedom = n-1 = 12-1 = 11 df.

The error in degrees of freedom = df (total) - df(treatment)

The error in degrees of freedom = 11 - 3 = 8 df

At α = 0.05 level,from the F table, the F-statistic with (3 , 8)df is 4.07.

Therefore, the F-statistic used to test the hypothesis that the miles per gallon for each fuel are the same is 4.07.

Suppose that the last dollar that Victoria receives as income brings her a marginal utility of 10 utils while the last dollar th

GaryK [48]

Answer: A

Suppose that the last dollar that Victoria receives as income

brings her a marginal utility of 10 utils while the last dollar that

Fredrick receives as income brings him a marginal utility of

15 utils. If our goal is to maximize the combined total utility of

Victoria and Fredrick, we should

a. Redistribute income from Victoria to Frederick

b. Redistribute income from Fredrick to Victoria

c. Not engage in any redistribution because the current situation already maximizes total utility

d. None of the above

Step-by-step explanation:

Marginal utility is the added satisfaction derived from consuming an additional unit of a good or service. In the above question, Fredrick derives more satisfaction from his last dollar than Victoria, and will therefore achieve a higher marginal utility with additional income than Victoria does with her current income. If we want to maximize the combined utility, we should redistribute income from Victoria to Fredrick.

The logic behind this is the diminishing marginal utility. The first unit of a good consumed gives the highest level of satisfaction, marginal utility reduces with additional units consumed. In the same way, when we spend our income, we purchase the things that give us the maximum satisfaction first.

Point A is at-4 and point B is at 6. Which describes one way to find the point that divides AB into a 3:2 ratio?

galben [10]

The point that divides AB into a 3:2 ratio is calculated by (d) for a ratio of 3:2, divide AB into 5 equal parts. Each equal part is 2 units, so the point that divides AB into a 3:2 ratio is 2

<h3>How to determine the ratio?</h3>

The given parameters are:

A = -4

B = 6

Start by calculating the length AB using:

AB = |B - A|

This gives

AB = |6 -(-4)|

Evaluate

AB = 10

Next, the length is divided into 5 parts.

So, the length of each part is:

Length = 10/5

Length = 2

The point on the location 3 : 2 is then calculated as:

Point = A + 3 * Length

This gives

Point = -4 + 3 * 2

Evaluate

Point = 2

The above computation is represented by option (d)
