Graph the pH function using the graphing utility. Then answer the questions. What is the pH of lemon juice that has a hydrogen ion concentration of 0.01 moles per liter? The pH is??

Answer:

pH = 2

Step-by-step explanation:

To graph the pH function :

The range of the pH function varies from 1 to 14

And the concentration of hydrogen ion goes from 0 to 1

Taking pH value on y-axis and concentration of hydrogen ion on x-axis, The resultant graph is attached below :

Given : Concentration of hydrogen ion = 0.01

Now, pH = -log(0.01)

pH=-\log(\frac{1}{100})\\\\pH=-(\log 1 - \log 100)\\pH=-(0-2)\\\implies\bf pH=2

Solutions to the quadratic equation x squared-5x-24=0

X^2-5x-24=0  

A quadratic of the form ax^2+bx+c can be factored by finding values j and k which satisfy two conditions, jk=ac and j+k=b, in this case:

ac=jk=-24 and b=j+k=-5, so j and k must be 3 and -8

Now replace bx with jx and kx in the original equation:

x^2+3x-8x-24=0  and factor 1st and 2nd pair of terms...

x(x+3)-8(x+3)=0  which is equal to:

(x+3)(x-8)=0  so

x=-3 and 8

QUESTION POSTED AT 17/10/2019 - 08:32 AM

In a city, 49% of the adults are male. Of the adults, 24% are male and rent action-movie DVDs and 10% are female and rent action-movie DVDs. If an adult is randomly picked, the probability that the person rents action-movie DVDs, given that the person is female, is .

Answer:

The probability that the person rents action-movie DVDs, given that the person is female, is 0.1960 ≈ 19%

Step-by-step explanation:

Given :

Adults that are male = 49%.

Of the adults, 24% are male and rent action-movie DVDs

10% are female and rent action-movie DVDs.

Solution :

Since this is conditional probability, we only have to consider the given scenario where the person surveyed is female.

Now, 49% of the adult are males  .

So, adult females will be 100%-49% = 51%

Now, we need to calculate the probability that the person rents action-movie DVDs, given that the person is female:

since 10% females are those who rents action DVDs and total female adults are 51%

P(females are those who rents action DVDs ) = 0.1

P(total female adults ) = 0.51

P( females are those who rents action DVDs  | the person is female) = 0.1/0.51 =0.1960

Thus, the probability that the person rents action-movie DVDs, given that the person is female, is 0.1960 ≈ 19%

QUESTION POSTED AT 17/10/2019 - 08:14 AM

Brendan got 31 questions correct on his social studies test and missed 9 questions. What percent did he have correct? Express as tenths.

Answer:

The answer is 77.5%

Step-by-step explanation:

Total questions Brendan solved are  = 31+9=40

Number of correct question he got = 31

Number of missed questions by him = 9

We have to find the correct answer percentage, so we will divide the correct answer by total questions multiplied by 100.

\frac{31}{10}*100 = 77.5%

Hence, the correct percent is 77.5 %.

QUESTION POSTED AT 17/10/2019 - 08:14 AM

What is the equation, in standard form, of a parabola that contains the following points? (-2,18),(0,4),(4,24)

Y=ax² + bx + c and A(-2,18), B(0.4), C(4,24) given

1)Let's determine 1st the value of c in using the pair of B
4= a(0)² + b(0) + c , c=4 and y=ax²+bx+4

2) Use the pair of A: 18 = 4a -2b + 4===> 4a-2b=14

3) Use C pair: 24 = 16a+4b+4 ==> 16a+4b=20

4) solve the system equation in 2) and 3) and you'll find a=2 and b=-3

Hence the equation  is y =2x²-3x+4

QUESTION POSTED AT 17/10/2019 - 08:00 AM

Read the following conjecture. Any number that is divisible by 4 is also divisible by 8. Find a counterexample to show that the conjecture is false. A) 24 B) 26 C) 12 D) 40

Answer:

Option C 12

Step-by-step explanation:

Given is one conjecture that

Any number divisible by 4 is also divisible by 8

Let x be the number

Since x is divisible by 4, x is of the form 4m for some integer m.

x=4m

If m is odd, then we find that x cannot be divisible by 8, since m is not divisible by 2.

If m is even, then x can be divisible by 8

Hence the conjecture is any number which is an odd multiple of 4.

Example 12

12 = 4x3

Since 3 is odd 12 though multiple of 4 cannot be multiple of 8.

What if you get a question like 3x-9y+3y=17 i need help

You solve for one of the variables.

3x-9y+3y=17  combine like terms on left side (3y-9y)

3x-6y=17  subtract 3x from both sides

-6y=17-3x  divide both sides by -6

y=(3x-17)/6

Since this is just a line, there are infinitely many solutions.  For every real value of x there will also be one real unique corresponding y value.  Or in other words there will by infinitely many unique (x,y) solutions to the original expression that you started with.
