Answer: $77.40

Step-by-step explanation:

First you take the 7.5% and turn it into a decimal and to do that you have to divide 7.5 by 100 which gives you .075. You then multiply 72 by .075 to know how much money you will pay with tax and you get $5.40. then you add $5.40 to $72 to get the total coast of the battery, which is $77.40.

The total cost of the battery was $77.40.

Answer:

P = 11,000(2)^t/11

Step-by-step explanation:

The formula is given as:

P = Po(2)^t/d

Where

Po = Initial population = 11,000

t = time in months

d = doubling time = 11 months

Hence,

P = 11,000(2)^t/11

Hence, the population of cats is given by the equation:

P = 11,000(2)^t/11

Answer:

in 9 hour 10 minutes the water level decreased = 5/12

in 550 minutes  the water level decreased = 5/12

in 60 minutes  the water level decreased = (5/12)/550*60

                                                                  = 1/22

Step-by-step explanation:

The rate of which water level decreases is 1/22 per hour.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Between time interval 9 P.M. and 6:10 AM,

The water level in the swimming pool decreases by 5/12.

To find the rate of decreasing water,

Total time duration = Final time - initial time = 9 : 10 hours = 540 + 10 = 550 minutes.

Since, in 550 minutes the water level decreases by 5/12.

To find water level decreases in each hour,

Use ratio property,

550 minutes = 5/12 decreases

1 minutes = 5/12 x 1/550 decreases

60 minutes = (5/12) x (60 / 550)

                   = 1 / 22

In each hour the water level decreases by 1/22.

Answer: C) local maximum at x = -3; local minimum at x = 1/3

Step-by-step explanation:

Given the function:

f(x) = x^3 + 4x^2 - 3x - 4

Set f'(x) = 0

f'(x) = 3x² + 8x - 3

f'(x) = 0

3x² + 8x - 3 = 0

Using the quadratic function calculator :

x = - 3 or x = 1/3

Critical points = - 3 ; 1/3

To find the maximum and minimum points :

f''(x) = 6x + 8

Substitute the values of X in

At x = - 3

6(-3) + 8

-18 + 8 = - 10

At x = 1/3

6(1/3) + 8

2 + 8 = 10

Value of f''(x) at - 3 is negative, hence - 3 is the maximum point

Value of f''(x) at 1/3 is positive , hence 1/3 is the minimum point

Domain:  since x begins to the right of x = -2 and ends at x =2, the domain is  (-2, 2]

Range:  The smallest y value shown is y = -5 and the largest is y = 4.  Thus, the range is [-5, 4].

Answer:

Width = 132 feet, Length = 291 feet

Step-by-step explanation:

perimeter (P) = 846

let width(W) = x

length(L) = 159 feet more than width = 159 + W= 159 + x

P of a rectangle = 2*(L + W)

846 = 2*((159 + x) + x)

divide both side by 2

423 = (159 + x) + x

423 = 159 + 2x

rearranging

2x + 159 = 423

2x = 423 -159

2x = 264

divide both sides by 2

x = 132 feet

recall W = x and L = 159 + x

W = 132 feet

L = 159 + 132 = 291 feet

Answer:

The probability is 0.5714

Step-by-step explanation:

This is a probability question. We are interested in calculating the probability that a random electrical engineering student is from section A.

Mathematically the probability will be;

Number of electrical engineering students in section A/ Total number of electrical engineering students in both sections

Total number of electrical engineering students = 128 - 60 -40 = 28

Now let’s calculate the number of electrical students from section A

Number of mechanical and electrical = 50-18 = 32

Now, there are a total of 60 mechanical engineers and 44 in B; So the number of mechanical engineers in A = 60-44 = 16

So the number of electrical engineers in A = 32-16 = 16

So the probability will be;

16/28 = 4/7 = 0.5714

Answer:

a. The definition that l and m are perpendicular if they meet at one point and one of the angles at their point of intersection is a right angle

The above definition is correct because, where two lines intersect, forming an angle of 90° with each other, then, by definition of perpendicular lines, the direction of one line is perpendicular to the other

The advantage of the above definition are;

1) It is simply stated and therefore, will be easier to understand

2) It can be easily used to test the perpendicular relationship between two objects

Disadvantages

1) It gives limited description of the other characteristics of the line

2) It does not state if the lines extend past each other after the point at which they cross

b. For the definition, l and m are perpendicular if they meet at one point and all four of the angles at their point of intersection are right angles

The above definition is correct as it meets the condition of two lines to be perpendicular to each other

Advantages

1) It clearly describes the relationship between the lines and their appearance

2) It indicates that the sun of angles at the point of intersection is 360°

Disadvantage

1) The resulting detail of the four angles may lead to ambiguity in the case where the two lines do not cross and there are only three angles formed at the point

c. For the definition, l and m are perpendicular if they meet at one point and reflection about l maps m to itself

The above definition is correct as it indicates the requirement for the continuity of the definition of the on line after crossing the other line

Advantages

1) It defines the condition of perpendicularity without the requirement for measuring the angles

2) It states the symmetrical condition of perpendicular lines about the vertical axis

Disadvantages

1) It requires further clarification in order to be related to the original definition of perpendicular lines being lines that are at right angle to each other.

First calculate how many pounds of apples you can buy for 20 dollars.

20/1.18 = 16.949 pounds

Now convert that to grams

1 pound = 454 grams

16.949   = x

Cross multiply

1 x = 16.949 * 454

x = 7694.915 grams.
