Can Someone Tell Me What The Value Of These Logarithms Are:

Answers

Answer 1

Answer:

4 and 4

Step-by-step explanation:

using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

(a)

let [tex]log_{3}[/tex] (81) = n , then

81 = [tex]3^{n}[/tex] = [tex]3^{4}[/tex] with n = 4

then [tex]log_{3}[/tex] (81) = 4

(b)

note that log(10,000) = [tex]log_{10}[/tex] (10,000)

let [tex]log_{10}[/tex] (10,000) = n , then

10,000 = [tex]10^{n}[/tex] = [tex]10^{4}[/tex] with n = 4

then log(10,000) = 4

What is a computer network?

Computer networking refers to the interconnection of computing devices that can exchange data and share resources. These networked devices use a set of rules known as communications protocols to transmit data over physical or wireless networks.

A computer network is a collection of computers that share resources that are located on or provided by network nodes. To communicate with one another, the computers use common communication protocols over digital interconnections.

Local-area networks (LANs) and wide-area networks (WANs) are the two basic network types (WANs). LANs connect computers and peripheral devices in a constrained physical area, such as a business office, laboratory, or college campus, using data-transmitting links (wires, Ethernet cables, fiber optics, Wi-Fi).

In this case, it should be noted that the security method that's used for allowing the connection is important. Based on the information illustrated, the correct option is B.

Answers

According to the central limit theorem, the standard deviation of the sample means is a) less than the population standard deviation.

What is a central limit theorem?

According to the central limit theorem, as long as the sample size is large enough, the sampling distribution of the mean will always be normally distributed. The sampling distribution of the mean will be normal regardless of whether the population has a normal, Poisson, binomial, or other distribution.

The sample means' standard deviation (also known as the standard error of the mean) will be less than the population standard deviation and equal to the population standard deviation divided by the square root of the sample size.

Ahmad and Daryl had an equal amount of money at first. Ahmad's father gave him another $180, and Daryl spent $255. Ahmad then had 4 times as much money as Daryl. How much money did each of them have at first?

Answers

Answer:

$400

Step-by-step explanation:

Suppose Ahmad and Daryl both started with the same x amount of dollars.

Ahmad gains another 180 from his father, so he now has x+180 dollars.

Daryl spends 255, so he now has x-255 dollars.

After these events, Ahmad has 4 times as much money as Daryl, so

x+180=4(x-255)

Now we can solve for x to get the original amount of money.

x+180=4(x-255)

x+180=4x-1020

1200=3x

x=400

Both Ahmad and Daryl started with $400.

The values are given below,

Left Hand Limit i.e. lim x -> 1- f(x) = 3 ,

Right Hand Limit i.e. lim x -> 1+ f(x) = 1 ,

Function value at x = 1 i.e. f(1) = 1 ,

Left Hand Derivative lim x -> 1- f'(x)= -6 and

Right Hand Derivative lim -> 1+ f'(x) = -6.

So, the function f(x) is neither continuous nor differentiable at x = 1.

Given, a piecewise function

              3㏑(3 - 2x) + 3                for x < 1

f(x) =

                   -3x² + 4                      for x ≥ 1

Now, for lim x -> 1- f(x) we will consider the function  3㏑(3 - 2x) + 3, as we have to find the Left Hand Limit of the function, at x = 1.

lim x -> 1 3㏑(3 - 2x) + 3 = 3㏑(3 - 2(1)) + 3

= 3 ㏑(1) + 3

= 0 + 3

= 3

Now, for lim x -> 1+ f(x) we will consider the function -3x² + 4, as we have to find the Right Hand Limit of the function, at x = 1.

lim x -> 1 -3x² + 4 = -3(1)² + 4

= -3 + 4

= 1

Now, for f( 1 ) we will consider the function -3x² + 4,

f(1) = -3(1)² + 4

= -3 + 4

= 1

Now, for lim x -> 1- f'(x) we will consider the derivative of the function

3㏑(3 - 2x) + 3,

lim x -> 1 -6/(3 - 2x) = -6/(3 - 2(1))

= -6

Now, for lim -> 1+ f'(x) we will consider the derivative of the function

-3x² + 4,

lim x -> 1 -6x = -6(1)

= -6

So, the function f(x) is neither continuous nor differentiable at x = 1.

Hence, lim x -> 1- f(x) = 3 , lim x -> 1+ f(x) = 1 ,  f( 1 ) = 1 , lim x -> 1- f'(x) = -6 and lim -> 1+ f'(x) = -6.

The function is neither continuous nor differentiable at x = 1.

Step-by-step explanation:

GH is one of the midsegments of triangle DEF. It divides both DE and EF to two equal segments (EH = HF, BG = GD).

A midsegment of a triangle has 3 characteristics:
- It splits the two sides it bisects into 2 equal segments.
- It is parallel to the side it doesn't bisect.
- It is equal to half the length of the side it doesn't bisect.

Applying the logic of the third characteristic, we can claim that GH = 1/2 * DF.

The polynomial function of least degree with leading coefficient 1 and having zero at the given points is, [tex]f(x) = x^3-3x^2+\sqrt{5}x^2 +2x-\sqrt{5} x[/tex].

What is polynomial?

A polynomial is an expression in mathematics that solely uses the operations of addition, subtraction, multiplication, and powers of positive-integer variables. It consists of indeterminates and coefficients. The polynomial x^2 + 4x + 7 is an illustration of one with a single indeterminate x.

From the given polynomial, the least degree polynomials are,

f(x) = x^3 -5x^2 + 3x - x

[tex]f(x) = x^3-3x^2+\sqrt{5}x^2 +2x-\sqrt{5} x[/tex]

These polynomial having leading coefficient 1.

Now to check x = 0, 1, (2 [tex]-\sqrt{5}[/tex]) are zeros of which polynomial.

Consider, the first polynomial

f(x) = x^3 -5x^2 + 3x - x

plug x = 0

f(0) = 0 - 5(0) + 3(0) - 0

f(0) = 0

plug x = 1

f(1) = 1^3 - 5(1)^2 +3(1) - 1

f(1) = 1 - 5 + 3 - 1

f(1) = -2

f(1) ≠ 0

Therefore, 1 is not the zero of this polynomial.

Now consider, the next polynomial

[tex]f(x) = x^3-3x^2+\sqrt{5}x^2 +2x-\sqrt{5} x[/tex]

Plug x = 0

f(0) = 0

f(1) = 0

[tex]f(2-\sqrt{5} )=0[/tex]

Therefore, the polynomial [tex]f(x) = x^3-3x^2+\sqrt{5}x^2 +2x-\sqrt{5} x[/tex] having given zeros.

Factor Theorem

If f(x) is a polynomial, and f(c) = 0, then (x – c)  is a factor of f(x).

Therefore, the function in factored form is:

[tex]\implies f(x)=1 \cdot x(x-1)(x-(2-\sqrt{5}))[/tex]

[tex]\implies f(x)=x(x-1)(x-2+\sqrt{5})[/tex]

What is the maximum height?
The rocket reaches its maximum height at ______ second(s) after launch.
(Simplify your answer.)
The maximum height reached by the object is ______feet.
(Simplify your answer.)

Answers

The rocket reaches its maximum height at 2.25 second(s) after launch

The maximum height reached by the object is 88 feet.

Time to reach the maximum height

The function is given as

h(t) = -16t² + 72t + 7

Differentiate the above function

So, we have the following representation

h'(t) = -32t + 72

Set to 0

-32t + 72 = 0

So, we have

32t = 72

Divide by 32

t = 2.25

Hence, the time is 2.25 seconds

The maximum height

In (a), we have

t = 2.25

Substitute t = 2.25 in h(t) = -16t² + 72t + 7

h(2.25) = -16(2.25)² + 72(2.25) + 7

Evaluate

h(2.25) = 88

Hence, the maximum height is 88 feet

what is the round figure of 2089.17​

Answers

2089.17 rounded off to nearest tenths(1 decimal place) is 2089.2

2089.17 rounded off to the nearest one is 2089

When you "round to the nearest _____" regardless of what is in the blank the steps are nearly always the same:

Identify which place value you are rounding off a number. The smaller the place value, the more accurate the final result shall be.

Find the next smallest place value, the digit to the right of the place value you're rounding off to. For example, if you want to round to the nearest ten you would have to find the number at the one's place.

If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round off. Any digits after that number become zeros, or drop-offs if they're located after the decimal point. This is called rounding down a number or a sequence of numbers.

If the smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding off to by one place (+1). Any remaining digits before the decimal point become zeroes, and any digits that are after the decimal point are dropped. This is called rounding up of numbers.

For example, for rounding off a number 838.274, depending on which place value you'll round to, the final rounded-off answer will vary. Rounding off 838.274:

Rounding off the nearest hundred is 800

Rounding off the nearest ten is 840

Rounding off the nearest one is 838

Rounding off the nearest tenth is 838.3

df Treatment, df Error and F value

The representation of the above parameters are:

The numerator degrees of freedom (df Treatment)The denominator degrees of freedom (df Error)

When these values are known, we look up to the df Treatment, df Error and F values on the anova table, and write out the corresponding p value

Take for instance:

F-value = 2.358, df Treatment = 2df Error = 27

The p-value for the above parameters is 0.1138

80% of what number is 280

Answers

Using the percentages formula, we know that 80% of 350 is 280.

What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.

So, let the number be x:

Then, 80% of x is 280:

Now, calculate as follows:

x/100 × 80 = 28080x = 280 × 10080x = 28000x = 28000/80x = 2800/8x = 350

Therefore, using the percentages formula, we know that 80% of 350 is 280.

A bag contains 10 red balls, 8 green balls, and 6 blue balls. 2 balls are drawn at random at the bag. What is the probability that both balls are red?​

Answers

Answer:

Assuming every single ball has an equal chance of being drawn, then if B is the probability of drawing a blue ball and R is the probability of drawing a red ball:

B + R = 1,

since either a red or blue ball will be drawn. Since each ball has an equal chance of being drawn:

16 p = 1, or

p = 1/16

where p is the chance to draw a single ball. Since there are 10 red balls, there are ten independent and different ways to draw a red ball, which means that

R = 10 p = 10/16 = 5/8.

You can either apply the first equation to find that

B = 1 - R = 3/8

or state directly that

B = 6 p = 6/16 = 3/8

since there are six independent and different ways to draw a blue ball from the bag.

Answer:

41.67%

Step-by-step explanation:

10+8+6= 24

10/24

First, you need to calculate your grade in percentages. The total answers count 24 - it's 100%, so we to get a 1% value, divide 24 by 100 to get 0.24. Next, calculate the percentage of 10: divide 10 by 1% value (0.24), and you get 41.67% - it's your percentage grade
