Answer:

187 units²

Step-by-step explanation:

break the figure into two rectangles

one 16 by 7 , the other 25 by 3

a = (16 * 7) + (25 * 3)

a = 187

Answer:

The function is maxima at x =  0.

Step-by-step explanation:

the function is

[tex]f(x) = x^4 - 8 x^2 + 3[/tex]

Differentiate with respect to x.

[tex]f'(x) = 4x^3 - 16 x\\\\Put f'(x) = 0 \\\\4x(x^2-4)=0\\\\4 x(x +2)(x-2) =0\\\\x = 0, - 2 , 2 Now f''(x) = 12 x^2 - 16 \\\\f''(0) = - 16 = negative \\\\f''(-2) = 12(-2)^2 - 16 = 32\\\\f''(2)=12(2)^2 - 16 = 32[/tex]

So, the function is maima at x = 0 .

Answer:

Quedan 153 sillas

Step-by-step explanation:

Primero sabemos que en una sala de teatro tenían 7 filas, y en cada una de esas filas habían 23 sillas.

Entonces, originalmente, el número total de sillas es 7 veces 23:

S = 7*23 = 161

Luego sabemos que quitan 8 de esas sillas, entonces el número de sillas que quedan es la diferencia entre el número original de sillas, 161, y 8, que nos da:

S = 161 - 8 = 153

Quedan 153 sillas

Answer:

5 + 2.5 > 4 feets

4 + 5 > 2.5 feets

2.5 + 4 > 5 feets

Step-by-step explanation:

The triangle states that :

The sum of any 2 sides of a triangle must be greater than the third side

Side Given are :

5feets ; 2.5 feets ; 4 feets

In other to obey the triangle rule :

5 + 2.5 > 4 feets

4 + 5 > 2.5 feets

2.5 + 4 > 5 feets

Answer:

4  14/25

Step-by-step explanation:

1 1/5 x 3 4/5 x 1

We need to convert the mixed number to an improper fraction

1 1/5 = (5*1+1)/5 = 6/5

3 4/5 = (5*3+4)/5  = 19/5

1 =1

6/5 * 19/5 *1

114/25

Now convert back to a mixed number

25 goes into 115 4 times with 14 left over

Answer:

Step-by-step explanation:

What is the margin of error if the sample size is 100, sample mean is 68.0, and standard deviation is 4.0

The Margin of error formula =

± z score × s/√n

Where s = standard deviation= 4

n= Number for samples = 100

z = z score of confidence interval

Margin of error = ± z × 4/√100

Margin of error = ±z × 4/10

=± z × 2/5

= ± z × 0.4

= ± 0.4z

Margin of error = ± 0.4z

Answer:

[tex]7.5\:\text{square units}[/tex]

Step-by-step explanation:

The area of a trapezoid is given by the average of the bases multiplied by the height.

What we're given:

The average of the bases 1 and 4 is equal to [tex]\frac{4+1}{2}=\frac{5}{2}=2.5[/tex]

Therefore, the area of the trapezoid is [tex]2.5\cdot 3=\boxed{7.5\:\text{square units}}[/tex]

Answer:

30 units²

Step-by-step explanation:

this ones kinda tricky but basically you need to dilate it all by 2 (to make the figure twice as big)

technically, it would be 7.5 units bc but bc of the dilation it'd be 30

Answer:

19 measures the median

Step-by-step explanation:

The dot plot is not shown, but the question can still be answered.

We have:

[tex]Samples: 18, 18, 18, 18, 20, 20, 22, 23[/tex]

[tex]n = 8[/tex]

Calculate the median position using:

[tex]Median = \frac{n + 1}{2}th[/tex]

[tex]Median = \frac{8 + 1}{2}th[/tex]

[tex]Median = \frac{9}{2}th[/tex]

[tex]Median = 4.5th[/tex]

4.5th means the median is the mean of the 4th and 5th item.

We have:

[tex]4th = 18[/tex]

[tex]5th = 20[/tex]

So:

[tex]Median = \frac{18 + 20}{2}[/tex]

[tex]Median = \frac{38}{2}[/tex]

[tex]Median = 19[/tex]

Answer:

64.05 in

Step-by-step explanation:

Lateral surface area of a cylinder = 2πrh

π= 3.14

r = radius = 9

h = height

3620 = 2 x 3.14 x 9 x h

3620 = 56.52h

h = 3620 / 56.52

h = 64.05 in

Answer:

After 60 minutes, Sam is 6 meters from the dock

Step-by-step explanation:

I looked at the number line and met up where 60 minutes was.

After 6 minutes, Sam is 60 meters from the dock

Correct option is D.

A straight line is an infinitely long line with no curves. A straight line can also be formed between two points, but the ends will be infinite. A straight line is a figure formed by connecting two points A (x1, y1) and B (x2, y2)  with the shortest distance and extending both ends to infinity.

General formula for a straight line:

The general equation for straight lines is given as ax + by + c = 0.

a, b, c are constants and

x,y are variables.

Slope is -a/b  

Given,

Graph of Distance to time is represented by an straight line

By the graph,

Line crosses from (0,20) and (3,40)

Equation of the line

y - y₁ = ((y₂ - y₁)/(x₂ - x₁))(x-x₁)

y - 20 = ((40 - 20)/(3 - 0))(x-0)

y - 20 = (20/3)(x)

y - 20 = 20x/3

y = 20x/3 + 20

Input x = 6

y = 20(6)/3 + 20

y = 120/3 + 20

y = 40 + 20

y = 60

When time = 6 minutes, distance between Sam and the dock is 60 meters.

Hence, Sam is 60 meters away from the dock after 6 minutes
