The area of a square is 64. What is the perimeter of the square?

Answer:

D.  4.5 sec

Step-by-step explanation:

Once the rock is on the ground it has no height (h=0)    

h = -16t² + 320

0 = -16t² + 320

16t² = 320

t² = 20

t² = 20

t = √20

t= √4x5

t = 2√5

around 4.5 seconds

Cylinder is consists of two circles at both sides .

There are two circles

Total area:-

The shape that makes up the top and bottom of a cylinder is Circle.

Where,

Since, There are two circles we will multiply the area by 2

[tex] \boxed{2\pi {r}^{2} }[/tex]

[tex]\red{ \rule{35pt}{2pt}} \orange{ \rule{35pt}{2pt}} \color{yellow}{ \rule{35pt} {2pt}} \green{ \rule{35pt} {2pt}} \blue{ \rule{35pt} {2pt}} \purple{ \rule{35pt} {2pt}}[/tex]

Some important formulas related to circle:

[tex] \boxed{ \sf \: circumference = 2\pi r}[/tex]

[tex] \boxed{ \sf \: area = \pi {r}^{2} }[/tex]

[tex] \boxed{ \sf \:radius = \frac{1}{2} \times diameter }[/tex]

[tex] \boxed{ \sf \:diameter = 2 \times radius }[/tex]

Part A: the composite shape is composed of a cone and a half sphere

Part B: The volume of the cone is 1186.92 And the volume of the half sphere is 1526.04

Part C: The volume of the composite shape is the solution of                                                          1186.92+1526.04 = 2712.96

The radius of both the cone and the half sphere is 9 inches and the hight of the cone is 14 inches, using the formula (volume = (1/3) · π · r2 · h) Putting the radius in the r spot and squareing it which is equal to 9x9=82 and putting the hight in the h and turning the pi symbol into 3.14 we get

Volume = (1/3) · 3.14 · 82 · 14

We get the volume of the cone which is 1186.92

Then we use the formula (volume = (4/3) · π · r3) putting the radius in where the r is which is equal to 9x9x9 And changing the pi symbol for 3.14 we get

volume = (4/3) · 3.14 · 729 ÷ 2) = 1526.04

We get the volume of the half sphere which is 1526.04

We then add all of it up to get 1186.92 + 1526.04 = 2712.96


I halved it because it's a half sphere

Using the Central Limit Theorem, it is found that since the sample size is greater than 30, a normal approximation can be used, hence the test can be made.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the sampling distribution is also approximately normal, as long as n is at least 30.

In this problem, the distribution of lengths is skewed, however, since the sample size is of 100 greater than 30, a normal approximation can be used, hence the test can be made.

Answer:

The exponential grows at approximately half the rate of the quadratic.

Step-by-step explanation:

Average rate of change of function f(x) over the interval a ≤ x ≤ b :

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

Interval: [tex]0\leq x\leq 1[/tex]

[tex]\implies a=0, b=1[/tex]

Quadratic function:  [tex]f(x)=2x^2[/tex]

[tex]\implies f(0)=2(0)^2=0[/tex]

[tex]\implies f(1)=2(1)^2=2[/tex]

[tex]\implies \textsf{Average rate of change}=\dfrac{f(1)-f(0)}{1-0}=\dfrac{2-0}{1}=2[/tex]

Exponential function:  [tex]f(x)=2^x[/tex]

[tex]\implies f(0)=2^0=1[/tex]

[tex]\implies f(1)=2^1=2[/tex]

[tex]\implies \textsf{Average rate of change}=\dfrac{f(1)-f(0)}{1-0}=\dfrac{2-1}{1}=1[/tex]

Therefore, the exponential grows at approximately half the rate of the quadratic in the interval [tex]0\leq x\leq 1[/tex]

Answer:

$12,000

Step-by-step explanation:

Use the simple interest formula: P = A(1 + rt)

P = final balance (?)

A = starting balance (10,000)

r = interest rate (0.05)

t = years (4)

P = 10,000(1 + 0.05 · 4)

P = 10,000(1 + 0.2)

P = 10,000(1.2)

P = 12,000

Answer:

Maria 69       Rizal    23

Step-by-step explanation:

M =Maria

(1/3)M = Rizal

                  M-46= (1/3)M

Multiply  both sides by 3 to eliminate fraction

3M-138 =M

138=2M

69= M   (Maria =69)

 69/3= 23

69-46=23

2 | 6, 9, 1, 1

1 | 7, 1, 1, 6, 8

4 | 4, 2, 4, 3, 4

Basically, you separate the given set of numbers by their whole number part (the digit before the decimal) and list the numbers' fractional part (digit after the decimal) in the order you see them.

The sorted diagram would then be

1 | 1, 1, 6, 7, 8

4 | 2, 3, 4, 4, 4

5 | 0, 2, 3, 5, 6

Step-by-step explanation:

the area of a circle is

A = pi × r²

the circumference of a circle is

C = 2 × pi × r

so,

A = pi × r² = 64 in²

r² = 64 / pi

r = sqrt(64 / pi) = 8×sqrt(1/pi) in

the circumference is then

C = 2 × pi × r = 2 × pi × 8×sqrt(1/pi) = 16×pi×sqrt(1/pi) =

Total number of employee working for four hours per shift for the manager is 2 people.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.

The probability of failure of an event is equal to the difference of the 1 to the success of the event.

Here, the manager records the number of hours, X, each employee works on his or her shift and develops the probability distribution below.

Probability Distribution

Hours Worked: X     Probability: P(X)

           3                         0.1

           4                           ?

           5                        0.14

           6                         0.3

           7                        0.36

           8                       0.06

As, the probability of an event can not be more than the number 1. Thus, the sum of all the probabilities will be equal to 1.

Let suppose the probability of people working for four hour is x. Therefore,

[tex]0.1+x+0.14+0.3+0.36+0.06=1\\x+0.96=1\\x=1-0.96\\x=0.04[/tex]

Now, the total number of people work for the manager is 50. Therefore, total number of people working for 4 hours are,

[tex]0.04\times50=2[/tex]

Hence, total number of employee working for four hours per shift for the manager is 2 people.

Step-by-step explanation:

132 + (4x - 10) + (5x - 11) + 128 + (4x+2) = 540 All convex 5 sided figures have  540 degrees.        Remove the brackets.

132+ 4x - 10 + 5x - 11 + 128 +4x + 2 = 540      Collect like terms

13x + 241 = 540                                               Subtract 241 from both sides.

13x = 540 - 241

13x = 299                                                         Divide by 13

x = 299/13
