Answer 1

Answer:

x = 2

Step-by-step explanation:

(x² logₓ27) log₉x = x + 4

Use change of base formula.

x² (log 27 / log x) (log x / log 9) = x + 4

Simplify.

x² (log 27 / log 9) = x + 4

x² (log 3³ / log 3²) = x + 4

x² (3 log 3 / (2 log 3)) = x + 4

x² (3 / 2) = x + 4

3x² = 2x + 8

3x² − 2x − 8 = 0

(x − 2) (3x + 4) = 0

x = 2 or -4/3

Since x > 0, x = 2.

Answer: [tex]2\frac{2}{3}[/tex]

Step-by-step explanation:

[tex]-2\frac{1}{3}-(-5)=[/tex]

Convert the mixed number to improper fraction. You can do this by multiplying the whole number times the denominator and adding the numerator; over the same denominator.

[tex]-\frac{2*3+1}{3} -(-5)=[/tex]

Solve;

[tex]-\frac{6+1}{3} -(-5)=[/tex]

[tex]-\frac{7}{3} -(-5)=[/tex]

Now, get rid of the two negatives by multiplying.

[tex]-\frac{7}{3} +5=[/tex]

Remember 5 has a 1 below; therefore, we can subtract these two fractions by getting both to a same denominator. Let's rewrite 5 as a fraction.

[tex]-\frac{7}{3}+\frac{5}{1} =[/tex]

To be able to convert 1 to 3, we have to multiply by 3. Remember that if you change the denominator, you have to change the numerator as well.

[tex]-\frac{7}{3}+\frac{5}{1} (\frac{3}{3} ) =[/tex]

Solve;

[tex]-\frac{7}{3}+\frac{15}{3} =[/tex]

Subtract numerators and keep the same denominator.

[tex]\frac{-7+15}{3}=\frac{8}{3}[/tex]

Convert to a mixed number. To do this, first, divide:

8/3=2

6

----

2

The 2 after the equal sign is the whole number, the two in the remainder is the numerator and the 3 is the denominator. Leaving our result as: [tex]2\frac{2}{3}[/tex]

Doug purchased land for $8,000 in 1995. The year value of the land depreciated by 4% each year thereafter. Use an exponential function to find the approximate value of the land in 2002.

Answers

Answer:

Option C. $6,012

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to

[tex]V=P(1-r)^{t}[/tex]

where  

V is the the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal

t is Number of Time Periods  

in this problem we have  

t = 7 years

P = $8,000

r = 0.04

substitute in the formula above

[tex]V = 8,000(1-0.04)^{7} = 6,012[/tex]

Scores on a math placement exam at UGA are normally distributed with a mean of 76 and a standard deviation of 6. What is the probability that an incoming freshman scores between 61.6 and 80.2?

Answers

Answer:

The probability that an incoming freshman scores between 61.6 and 80.2 is 0.7498

Step-by-step explanation:

We are given that Scores on a math placement exam at UGA are normally distributed with a mean of 76 and a standard deviation of 6.

Mean = [tex]\mu = 76[/tex]

Standard deviation =[tex]\sigma = 6[/tex]

we are supposed to find the probability that an incoming freshman scores between 61.6 and 80.2 i.e. P(61.6<x<80.2)

Formula : [tex]Z=\frac{x-\mu}{\sigma}[/tex]

At x = 61.6

So,[tex]Z=\frac{61.6-76}{6}[/tex]

Z=-2.4

Refer the z table for p value

So,p value =0.0082

At x = 80.2

So,[tex]Z=\frac{80.2-76}{6}[/tex]

Z=0.7

Refer the z table for p value

So,p value =0.7580

P(61.6<x<80.2)=P(x<80.2)-P(x<61.6)=0.7580-0.0082=0.7498

Hence the probability that an incoming freshman scores between 61.6 and 80.2 is 0.7498

Express your answer in scientific notation. 4.9 x 10^4 - 8200

Answers

Answer:

4.0800*10^4

Step-by-step explanation:

4.9*10^4=49000

49000-8200=40800

since we can only have base numbers 1-9 in scientific notation, we need to move the decimal left 4 places:

4.0800*10^4

Hope this helps!

The scientific notation, of the given number is 4.0800×10⁴

Given the number is 4.9×10⁴-8200

4.9×10⁴ = 49000

49000-8200 = 40800

Since we can only have base numbers 1-9 in scientific notation, we need to move the decimal left 4 places:

4.0800×10⁴

Hence, the scientific notation, of the given number is 4.0800×10⁴

Value of y > 0 at [tex]x = \{0, 1, 2, 3, 4\}[/tex]

Step-by-step explanation:

As seen from the graph attached in answer area as well, The graph is above  x-axis (i.e. y value of equation) only when x has values {0, 1, 2, 3, 4}.

At x = 0:

[tex]y = -|0-2| + 2 \\\Rightarrow -2 + 2\\ \Rightarrow y = 0[/tex]

At x = 1:

[tex]y = -|0-1| + 2 \\\Rightarrow -1 + 2\\ \Rightarrow y = 1[/tex]

At x = 2:

[tex]y = -|2-2| + 2 \\\Rightarrow 0 + 2\\ \Rightarrow y = 2[/tex]

At x = 3:

[tex]y = -|3-2| + 2 \\\Rightarrow -1 + 2\\ \Rightarrow y = 1[/tex]

At x = 4:

25
what is the slope of
line p?

Answers

Answer:

The slopes of line m and p will be the same: 1/25 (I think thats what that says)

Step-by-step explanation:

when two lines are parallel it means they will never touch, and so they must have the same slope. If their slopes were different (even by 1 decimal), they would touch and so would no longer be parallel.

If lines m and p are parallel, they have the same slope. so slope of  line p is 1/25

What is the equation of line?

The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.

Given that the slope of line m is 1/25, we can conclude that the slope of line p is also 1/25.

This is because parallel lines have equal slopes.

That is, if two lines are parallel, they have the same steepness or angle of inclination, which means they have the same slope. Therefore, the slope of line p is also 1/25.

How many solutions are possible for this situation?
Infinitely many solutions exist because the two situations describe the same line.
Exactly one solution exists because the situation describes two lines that have different slopes and different y-intercepts.
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Exactly one solution exists because the situation describes two lines with different slopes and the same y-intercept.

Answers

Answer:

Answer: No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Step-by-step explanation:

Let n equal the number, and let x equal the smaller number. Let's put this into equation form to make everything easier to understand.

x < n

n = 2x + 3

n = 2x + 1

Note how n equals two different things. In other words, how can n equal 2x + 3, but also equal 2x + 1? The equations have different y-intercepts but the same slope, meaning there are no solutions, or points where the lines would intercept. The only answer that highlights this is the third option.

To further clear things up, let's go through the other answers to make sure we're correct.

Answer 1: Two situations do not describe the exact same line; all parts of the question are unique.

Answer 2: The equations do not have different slopes, so this reasoning is invalid.

Answer 4: The situations describe two equations with the same slope but different y-intercept, not the other way around. In equation form, 2 = 2, but 3 ≠ 1.

Therefore, the only correct answer is option 3.
