What is the best estimate of the area of the figure if each square has a side length of 1 mm?
27 square millimeters
36 square millimeters
39 square millimeters
46 square millimeters

Answers

Answer:

  (c)  39 mm²

Step-by-step explanation:

You want to know an estimate of the area of the irregular figure.

Decomposition

The areas of irregular figures are often easily computed by decomposing the figure into shapes whose areas have formulas. Here, we can draw a vertical line from the upper left vertex to divide the figure into a triangle on the left and a trapezoid on the right.

Triangle

The triangle has a base of 3 squares and a height of 6 squares, so an area of ...

  A = 1/2bh = 1/2(3)(6) = 9 . . . . square mm

Trapezoid

The trapezoid has vertical parallel bases of 6 and 7 squares, and a width of 5 squares. Its area is ...

  A = 1/2(b1 +b2)h = 1/2(6 +7)(5) = 65/2 = 32 1/2 . . . . square mm

Total area

Then the total area of the figure shown is ...

  area = triangle area + trapezoid area

  area = 9 mm² +32.5 mm² = 41.5 mm²

The closest estimate of those offered is 39 square mm.

A line with a slope of 14/3 passes through the point (0,8). What is the equation in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

The equation of slope-intercept form of the line is y = 14/3x + 8.

What is in slope-intercept form?

Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form. Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.

Given,

        m = 14/3

the point = ( 0,8 )

A line with a slope of 14/3 passes through the point (0,8).

y - y₁ = m ( x- x₁)

y - 8 = 14/3 ( x - 0 )

3(y - 8 )  = 14x

3y - 24  = 14x

3y = 14x + 24

y = 14/3x + 8

Finally, the equation of the line is

y = 14/3x + 8

fence they need costs $5 per foot. How much will the fence cost? Do not calculate sales tax. Show your
work and justify your solution.

Answers

Answer: $180

Step-by-step explanation:

a right triangle has three sides: the two smaller ones and the big one. the two smaller ones squared add up to the bigger one squared.

this is the pythagorean theorem, a^2 + b^2 = c^2.

in this case, it would be 9 squared + 12 squared = c squared.

81 + 144 = 225

225 is the square of 15, so the third side is 15.

now, solve for the perimeter.

the perimeter is the 3 sides added up, so 9+12+15 = 36 feet of perimeter.

each foot costs $5, so 36x5= 180.

$180 is the answer.

Using the normal distribution, it is found that the z-score of the height of a women 5.5 feet tall is 0.51.

What is the missing information?

The problem asks for the z-score of the height of a women 5.5 feet tall.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

Considering that each feet has 12 inches, the parameters are given as follows:

[tex]X = 5.5 \times 12 = 66, \mu = 64.1, \sigma = 3.7[/tex]

Hence the z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (66 - 64.1)/3.7

Z = 0.51.

Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.

Let the required score be x

Mean = 79 + 69 + 61 + 91 + x/5

⇒ 79 + 69 + 61 + 91 + x/5 > 75

⇒ 300 + x/5 > 75

⇒ 300 + x > 375

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion
s = 5 sin(t) + 5 cos(t),
where t is measured in seconds. (Round your answers to two decimal places.)
(a) Find the average velocity during each time period.

(1)[1,2]? cm/s
(2)[1,1.1]? cm/s
(3)[1,.101]? cm/s
(4)[1,1.001]? cm/s
(b) estimate the instantaneous velocity of the particle when t = 1? cm/s

Answers

a) the average velocity during each time period.

(1) 4.87 cm/s(2) 4.90 cm/s(3) 4.95 cm/s(4)  4.91 cm/s

(b) 0.08 cm/s is the instantaneous velocity of the particle when t = 1.

Step-by-step explanation:

Given that

the equation of motion

                s = 5 sin(t) + 5 cos(t),

To find

a) The average velocity during each time period.

                (1)[1,2]? cm/s

                (2)[1,1.1]? cm/s

                (3)[1,.101]? cm/s

                (4)[1,1.001]? cm/s

b) The instantaneous velocity of the particle when t = 1? cm/s

So, according to the question

a) The average velocity during each time period.

                (1)[1,2]? cm/s

                (2)[1,1.1]? cm/s

                (3)[1,.101]? cm/s

                (4)[1,1.001]? cm/s

We have the displacement equation at time t :

                s = 5 sin(t) + 5 cos(t)

Now differentiate it by t to get velocity.

               v(t) =  ds/dt

                     [tex]= \frac{d}{dt} (5sint+5cost)\\= 5(\frac{d}{dt} sint+\frac{d}{dt}cost)\\\\[/tex]

              v(t)  [tex]= 5( cost - sint)[/tex]    

velocity at t = 1,

               v(1) = 5 { cos(1)- sin(1) }    = 5( 0.99-0.017) = 5 x 0.982 = 4.91 cm/s        

velocity at t = 2,

               v(2) = 5 { cos(2)- sin(2) }    = 5( 0.999 - 0.0348)  = 4.82 cm/s  

velocity at t = 1.1,

               v(1.1) = 5 { cos(1.1)- sin(1.1) }    = 5( 0.999 - 0.0191)  = 4.90 cm/s  

velocity at t = 0.101,

          v(0.101) = 5 { cos(0.101)- sin(0.101) } = 5( 0.999 - 0.0176)  = 4.99 cm/s

velocity at t = 1.001,

         v(1.001) = 5 { cos(1.001)- sin(1.001) } = 5( 0.999 - 0.0174)  = 4.911 cm/s    

Now,

The average velocity at [1,2]

          = (4.91+4.82)/2 = 4.87 cm/s

The average velocity at [1,1.1]

          = (4.91+4.90)/2 = 4.90 cm/s

The average velocity at [1,0.101]

          = (4.91+4.99)/2 = 4.95 cm/s

The average velocity at [1,1.001]

          = (4.91+4.911)/2 = 4.91 cm/s

b) instantaneous velocity at 1s.

        instantaneous velocity[tex]= \frac{instantaneous\; displacement }{instantaneous\; time}[/tex]

                                   v(1) = [tex]\frac{s(1)-s(0)}{1-0}[/tex]

  s(1) = 5 {sin(1) + cos(1)} = 5 (0.017 + 0.999) = 5.08 cm

  s(0) = 5 {sin(0) + cos(0)} = 5 (0 + 1) = 5.0 cm

Now, putting the all values

                v(1) = (5.08 - 5.0)/1 = 0.08 cm/s

Answer:

   a) the average velocity during each time period.

(1) 4.87 cm/s(2) 4.90 cm/s(3) 4.95 cm/s(4)  4.91 cm/s

  (b) 0.08 cm/s is the instantaneous velocity of the particle when t = 1.

Answers

Answer: Depth d = 767 feet.

Step-by-step explanation:

In certain deep parts of oceans, the pressure of sea water, P, in pounds per square foot, at a depth of D feet below the surface, is given by the following equation:

                               P= 13+ 5d/13

If a scientific team uses special equipment to measures the pressure under water and finds it to be 308 pounds per square foot, at what depth is the team making their measurements?

Given data,

The relationship between the pressure, p of sea water in certain deep parts of oceans is and the distance, d below the surface is given by the following equation,

                                 P= 13+ 5d/13

Where,

p is in pounds per square foot.

d is in feet

The pressure of seawater is 308 pounds per square foot at a depth

                             308 = 13+ 5d/13           (eq-1)

                             308 - 13 = 5d/13

Cross multiplying, it becomes                            

                             295 = 5d/13

                             295 * 13 = 5d

                              3,835 = 5d

                               3,835/5 = d

                                d = 767 feet

At a depth of 308 feet below the surface of the water, the pressure of seawater is,

Substitute d value in equation 1,

So, we can write,

                              P= 13+ 5d/13

                              P = 13+ 5 (767) /13

                              P = 13 + 3835/13

                              P = 13 + 295

                              P = 308 pounds per square foot.

Therefore,

Using proportions, it is found that:

a) 75% of the respondents believe the action is morally​ acceptable.

b) Supposing there are 217 million adults, 39.06 million believe that the action is morally​ wrong.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

In item a, 75 out of 7 + 18 + 75 = 100 adults believe that the action is morally acceptable, hence the percentage is:

75/100 x 100% = 75%

75% of the respondents believe the action is morally​ acceptable.

In item b, we suppose that there are 217 million adults, hence the amount that believe the action is morally wrong is:

The length of the KL by additive property is 5 units.

The additive property of equality in an equation asserts that the sides stay equal whether we add or subtract the same amount from both sides of the equation. For entire numbers as well, this property is valid.

An example of the additive property is :

If A=B then A+n=B+n where n∈R.

Now the given line segment is KM is x+10

And KL=5x and LM=6

Now using additive property we can say that

Substituting the values in the equations we get:

5x+6=x+10

or, 4x=4

or, x=1

Now using this value of x we can find the length of KL.

Therefore KL=5x=5×1=5

Hence the length of the KL by additive property is 5 units.
