The square of a number added to 2 times a number is 8. Find the number.

Answers

Answer:

x = -4 or 2

Step-by-step explanation:

Let the number be x.

Given condition:

x² + 2x = 8

Subtract 8 to both sides

x² + 2x - 8 = 0

Using mid-term break method

=> 4 × -2 = 8 (side-term), 4 - 2 = 2 (mid-term)

So, we can break the mid-term into 4 and -2.

x² + 4x - 2x - 8 = 0

Take common

x(x + 4) - 2(x + 4) = 0

Take (x+4) common

(x+4)(x-2) = 0

Either

x + 4 = 0       OR      x - 2 = 0 (Zero's method)

x = -4            OR       x = 2

8x - 4y = -4 solve for y.

Answers

The equation 8x - 4y = -4 have y as the subject to be equal to 2x + 1 expresses in terms of x.

How to evaluate for y

To solve for y in the equation 8x - 4y = -4, we must make y the subject and it should be positive as follows;

8x - 4y = -4

add 4y to both sides

8x - 4y + 4y= -4 + 4y

8x = - 4 + 4y

also to make y the subject;

- 4 + 4y = 8x

add 4 to both sides

- 4 + 4 + 4y = 8x + 4

4y = 8x + 4

factorize the right hand side

4y = 4(2x + 1)

divide through by the coefficient of y

4y/4 = [4(2x + 1)]/4

y = 2x + 1

Hence, the equation 8x - 4y = -4 has y = 2x + 1

The odds in favor of Michael Jordan making a free throw were 21:4. Find the probability of Michael Jordan missing a free throw.

Give answer as a decimal rounded to the nearest hundredth.

Answers

The probability that Jordan misses a free throw is 0.16

How to determine the probability that he misses?

From the question, we have the following parameters that can be used in our computation:

Odds in favour = 21 : 4

Represent the odds as a fraction

So, we have the following representation

Odds in favour = 21/4

To convert the odds to probability, we make use of the following equation

Probability = Numerator/(Numerator + Denominator)

Substitute the known values in the above equation, so, we have the following representation

Probability = 21/(21 +4)

Evaluate the sum

Probability = 21/25

The probability that he misses is

Misses = 1 - 21/25

Evaluate the probability

Misses = 4/25

So, we have

Misses = 0.16

Hence, the probability is 0.16

Answers

Step-by-step explanation:

Also, we know that , because the unit digit is three less than tens digit, or tens digit is three more units than the unit digit. Then, the sum of the reversed number and the original number is 121, this would be expressed: Therefore, the digits are 7 and 4. The number would be 74.

Answer:

The original number is 74

Step-by-step explanation:

The answer of 74 provided by brey90 is absolutely correct. I am just providing a mathematical way of determining the number

Let the number be ab
That means [tex]b[/tex]  is in the units place and [tex]a[/tex] is in the tens place.

The actual value of this two digit number is  [tex]10a + b[/tex]  

The difference between a and b is 3:
[tex]a - b = 3[/tex]  [1]

If we reverse the number we get the number [tex]ba[/tex]

The actual value of [tex]ba[/tex] is [tex]10b + a[/tex]

The sum of [tex]ab[/tex] and [tex]ba[/tex] is 121. This means the sum of their actual values must be 121

So we get
[tex]10a + b + 10b + a = 121\\\\11a + 11b = 121\\\\[/tex]

Dividing both sides by 11 yields:
[tex]a + b = 11[/tex]  [2]

Add [1] and [2] to get:
[tex]2a = 14\\\\a = 7\\\\[/tex]

Sub for a in Equation [1] to get
[tex]7 - b = 3\\\\b = 4\\\\[/tex]

So the original number is 74

Check
Reversed is 47
74 + 47 = 121

A rumor about canceling spring break is being spread around a school. The following equation models the number of students in the school who have heard the rumor after t days:

Equation: N (t) = 1800/1+149e^-0.625t

A.). How many people started the rumor?

B. ). How many students are in the school?

C.). To the nearest 1/10, how many days will it be before the rumor spreads to ½ the student body?

D.). The following equation represents the instantaneous rate of change in students per day of the spread of the rumor.

Another Equation: N^1 (t)=0.625N (1- N/1800)

N represents the number of students who have heard the rumor and t is time in days.

How many students have heard the rumor when the rumor is spreading the fastest?

What is the rate of change in students per day at this time ?

Answers

A) The number of people who have started the rumor is N(0)=12

B) The number of students who are in the school are 1800

C) The number of days the rumor spreads to ½ the student body are 8 days.

D) The number of students who have heard the rumor when the rumor is spreading the fastest are 900.

The rate of change in students per day at this time is 281.

What is meant by rate of change?

The rate of change is a mathematical term that describes the percentage change in value over a given time period and represents the momentum of a variable.

A) Number of people who have heard the rumor after t days is given by:

N (t) = 1800/1+149e^-0.625t

At start t=0, so from the above equation at t=0, we get

N(0)=(1800)/1+149e^0

N(0)=1800/(1+149(1))

N(0)=1800/150

N(0)=12

B) At t=∞, all of the students would have heard the rumor.  So putting t↔∞ in the above equation we get,

[tex]\lim_{t \to \infty}[/tex]N(t)=[tex]\lim_{t \to \infty}[/tex] 1800/1+149e^-0.625t

=1800/(1+0)

=1800

Therefore, the number of students in the school are 1800.

C) Putting N=1800/2 in the above equation, we get

1800/2= 1800/1+149e^-0.625t

1+149e^-0.625t=2

e^-0.625t=(2-1)/149

=1/149

Taking log on both sides, we get

ln(e^-0.625t)=ln(1/149)

-0.625t=-ln(149)

t=ln(149)/0.625

t=8.006≈8

D) N'(t)=0.625N(1-(N/1800)

=0.625(N-(N²/1800)

=(0.625/1800)(1800N-N²)

=(0.625/1800)(900²-900²+1800N-N²)

=(0.625/1800)(900²-(N²-1800N+900²)

N'(t)=(0.625/1800)(900²-(N-900)²)

For N to be maximum,

N=900

Thus, rumor is spreading fastest when 900 students have heard the rumor.

And rate of change in students per day is obtained by putting N=900 in expression of N'(t) as follows:

N'(t)=(0.625×900)(1-(900/800))

N'(t)=281.25≈281

Suppose that we have a function y = f(x), and wish to find the rate of change of y with respect to a third variable t, where we do not have y expressed explicitly in terms of t. We use the chain rule in differentiation to find this rate of change in a process called implicit differentiation.

Explain the term acid form?Typical aqueous acids include acetic acid, hydrochloric acid, and gastric acid, which activates digestive enzymes. Hydrochloric acid is a solution containing hydrogen chloride.

Using the Henderson-Hasselbalch equation to determine the indicator's pH  is as follows:

pH = pKa + log[In⁻]/[HIn]

In which,

Ka = dissociation constant of acid.

As the stated value-

Part a:

pKa = 9.7

pH = 5.3

Thus,

5.3 = 9.7 + log[In⁻]/[HIn]

log[In⁻]/[HIn]  = - 4.4

[In⁻]/[HIn] = Antilog (-4.4)

[In⁻]/[HIn] = 4.0 × 10⁻⁶

Part b:

pKa = 9.7

pH = 11.4

Thus,

11.4 = 9.7 + log[In⁻]/[HIn]

Here we need to find how many different passwords are possible.

Total number of characters = 6

According to this, each password would have

5 digits of 10 digits: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], and

one of 26 letters: [A to Z].

Here there is no repeats are allowed, and assuming only upper case letters are valid and the letter is the last character, then we can form 10*9*8*7*6 * 26 = 786,240 such passwords.

If the repetition is allowed then number of possible passwords is

786,240 * 6 = 4,717,440.

a group of 15 people are ordering pizza each person wants 2 slices and each pizza has 15 slices how many pizzas should they buy

Answers

By conducting mathematical operations, we know that the group of friends will order 6 pizzas.

What are mathematical operations?

An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.

The operation's arity is determined by the number of operands.

Mathematical operations include addition, subtraction, multiplication, division, and finding the root.

So, a number of pizzas the friends should buy:

We know that a group is of 15 people.

They are ordering a pizza which have also 15 slices in each.

And each person wants 2 slices: That is

Then, the number of pizzas they have to order will be:

1 pizza (15 slices) * 2 = 2 pizza (30 slices)

Therefore, by conducting mathematical operations, we know that the group of friends will order 6 pizzas.

How can the average rate of a function over an interval be found?

The average rate of change of a function over an interval is found from the change in the output values of the function over the period indicated, divided by the change in the input values of the function over the specified interval.

Average rate of change = [tex]\dfrac{\Delta y}{\Delta x}[/tex]

The interval over which the average rate of change of the function is required = [-4, -1]

The formula for the average rate of change over the interval, [-4, -1], can be presented as follows;

Average rate of change = [tex]\dfrac{\Delta y}{\Delta x}[/tex]  =  [tex]\dfrac{f(-1) - f(-4)}{\left(-1 - (-4)\right)}[/tex]

The coordinates of the points of the graph of the function in the indicated range are; (-1, 3), and (-4, -3)

f(-1) = 3, f(-4) = -3, therefore;

Average rate of change = [tex]\dfrac{3 - (-3)}{-1 - (-4)}[/tex] = 2

The average rate of the function over the specified interval is 2
