Answer:
x = 1 and x = 2
x = 4 and x = -4
Step-by-step explanation:
Vertical asymptotes appear where the function does not have a value. This is most commonly when the denominator of a rational function is 0. Find the asymptotes by factoring the denominator and setting it equal to 0. Then solve for x.
First equation
x² - 3x + 2 factors into (x-1)(x-2)
When x-1 = 0, x = 1. When x-2=0, x = 2. The V.A. are at x = 1 and x = 2.
Second equation
x² - 16 factors into (x+4)(x-4)
When x+4= 0, x = -4. When x-4 = 0, then x = 4. The V.A. are at x = -4 and x = 4.
Final answer:
The function f(x) = 3x/(x² - 16) is defined for x = -16, x = 0, and x = 16, but undefined for x = -4 and x = 4, where it has vertical asymptotes.
Explanation:
The question requires evaluating the function f(x) = 3x/ x²-16 for different values of x. When we evaluate this function, we must pay attention to the values at which the function is undefined, which is when the denominator x^2 - 16 equals zero. This occurs when x = -4 or x = 4, as these values make the denominator (x + 4)(x - 4) equal to zero.
For x = -16, the function is defined and f(-16) can be calculated.For x = -4, the function is undefined as the denominator will be zero.For x = 0, the function is defined and f(0) = 0.For x = 4, the function is undefined as well.For x = 16, the function is defined and f(16) can be calculated.Options (b) and (d) correspond to the values at which the function has vertical asymptotes, as the denominator becomes zero and the function value approaches infinity.

Kelly paid $54.60 for a bike helmet that was 20% off the original price. What was the original price
Answers
The original price of the bike helmet was $68.25, calculated by understanding that the $54.60 Kelly paid represented 80% of the original price after a 20% discount.
Explanation:Kelly paid $54.60 for a bike helmet that was 20% off the original price. To find the original price of the helmet, we need to understand that the price Kelly paid is 80% of the original price, after the discount was applied. Therefore, the equation to find the original price (OP) is:
54.60 = 0.80 × OP
To solve for OP, we divide both sides of the equation by 0.80:
OP = 54.60 / 0.80
OP = $68.25
Thus, the original price of the bike helmet was $68.25.

Answer:
A) 0.5000; B) 0.9772; C) 0.9772; D) 0.8185; E) 0.9932; F) 1.0000
Step-by-step explanation:
For each of these, we will use a z score. The formula for a z score is:
[tex]x=\frac{X-\mu}{\sigma}[/tex]
A) Our X is 5, our mean is 5 and our standard deviation is 0.2:
z = (5-5)/(0.2) = 0/0.2 = 0
Using a z table, the value to the left of this, less than, is 0.5000; this means the area to the right of this, greater than, is 1-0.5000 = 0.5000.
B) Our X is 5.4, the mean is 5 and the standard deviation is 0.2:
z = (5.4-5)/0.2 = 0.4/0.2 = 2
Using a z table, the value to the left of this, less than, is 0.9772.
C) The probability for this will be the same as for B; there is no distinction between "less than" and "less than or equal to" in z tables.
D) We find the z score for each of the endpoints of this interval, find the probabilities and subtract them:
z = (4.6-5)/0.2 = -0.4/0.2 = -2; the probability is 0.0228.
z = (5.2-5)/0.2 = 0.2/0.2 = 1; the probability is 0.8413.
The area between them is 0.8413-0.0228 = 0.8185.
E) X is 4.5, the mean is 5 and the standard deviation is 0.2:
z = (4.5-5)/0.2 = -0.5/0.2 = -2.5; the probability less than this is 0.0062. This means the probability greater than this is 1-0.0062 = 0.9938.
F) X is 4, the mean is 5 and the standard deviation is 0.2:
z = (4-5)/0.2 = -1/0.2 = -5. Everything in the z table is larger than this, so the probability is 1.000.
Predict how many times you will roll a number less than 5 if you roll a standard number cube 250 times
Answers
Final answer:
The probability of rolling a number less than 5 on a six-sided die is 2/3. When rolling the die 250 times, this probability suggests that a number less than 5 would be rolled approximately 167 times.
Explanation:
To predict the number of times you will roll a number less than 5 when rolling a standard six-sided die (with faces numbered 1 through 6), it's important to first understand the probability of rolling a number less than 5 for any single roll. Our numbers of interest here are 1, 2, 3, and 4.
The probability P of rolling any one of these four numbers on a six-sided die is 4 out of 6 (since there are 4 favorable outcomes and 6 possible outcomes in total), which simplifies to 2/3. This means that on any given roll, you have a 2/3 chance of rolling a number less than 5.
When rolling the die 250 times, we would expect this 2/3 probability to hold true on average. Therefore, we calculate the expected number of times a number less than 5 appears as follows:
Expected number of rolls less than 5 = Total number of rolls × Probability of rolling a number less than 5
Expected number of rolls less than 5 = 250 × 2/3
Expected number of rolls less than 5 = approximately 166.67
Since we cannot roll a die a fraction of a time, we would predict that you would roll a number less than 5 approximately 167 times out of 250 rolls.
A card is drawn from a well-shuffled deck of 52 cards. What is the probability that a red card appears?

Answers
Answer:
P (red) = 1/2
Step-by-step explanation:
It is given that a card is drawn from a well-shuffled deck of 52 cards and we are to find the probability of getting a red card.
We know that there are total 26 red cards in a deck (13 hearts and 13 diamonds).
Therefore, the probability of getting a red card P (red) = [tex] \frac { 2 6 } { 5 2 } [/tex] = 1/2
The probability of drawing a red card from a well-shuffled 52-card deck is 1/2 since half of the cards in the deck are red (26 out of 52)
Explanation:This question pertains to the topic of probability in Mathematics. There are 52 cards in a standard deck, half of which are red (26 red cards: 13 hearts and 13 diamonds). Hence, the probability of drawing a red card is the number of red cards over the total number of cards in the deck.
So, the probability of drawing a red card from a well-shuffled 52-card deck is 26/52, simplified to 1/2. Hence the correct answer from the given choices is 1/2.

Answer:
The correct answer option is P(Both Work) = 435 / 703
Step-by-step explanation:
We are given that in a box of total 38 bulbs, 8 are the defective ones while the rest are good.
If Ken selects two bulbs at random from the box, we are to find the probability that they both work.
1st bulb: P (bulb works) = [tex]\frac{30}{38} [/tex]
2nd bulb: P (bulb works) = [tex]\frac{29}{37} [/tex]
P (Both Work) = [tex]\frac{30}{38} \times \frac{29}{37}[/tex] = 435 / 703
Answer:
The correct answer is first option. P(Both Work) = 435/703
Step-by-step explanation:
It is given that,
There are 8 burned bulbs and 30 good bulbs.
Therefore total number of bulbs = 8 + 30 = 38
To find the probability
We have to take two working bulbs from total bulbs.
Total bulbs = 38
The probability of taking two working bulbs = P(Both Work)
P(Both Work) = 30C₂/38C₂
= (30 * 29)/(38 * 37) = 435/703

A rectangle whose area is 180 square feet has a width that is 3 feet less than the length. Find the dimensions of the rectangle.
Answers
Answer:
The length is [tex]15\ ft[/tex]
The width is [tex]12\ ft[/tex]
Step-by-step explanation:
we know that
The area of rectangle is equal to
[tex]A=LW[/tex]
we have
[tex]A=180\ ft^{2}[/tex]
so
[tex]180=LW[/tex] -----> equation A
[tex]W=L-3[/tex] ------> equation B
substitute equation B in equation A and solve for L
[tex]180=L(L-3)[/tex]
[tex]180=L^{2}-3L[/tex]
[tex]L^{2}-3L-180=0[/tex]
using a graphing tool------> solve the quadratic equation
The solution is [tex]L=15\ ft[/tex]
see the attached figure
Find the value of W
[tex]W=15-3=12\ ft[/tex]
To find the dimensions of the rectangle given its area, we set up an equation using the length and width of the rectangle. Solving the equation will give us the dimensions. In this case, the length of the rectangle is 15 feet and the width is 12 feet.
Explanation:To find the dimensions of the rectangle, let's assume the length of the rectangle is L feet. According to the problem, the width is 3 feet less than the length, so the width would be L - 3 feet. The area of the rectangle is given as 180 square feet, so we can set up the equation: L * (L - 3) = 180. Solving this equation will give us the dimensions of the rectangle.
Multiplying the binomials, we get L^2 - 3L = 180. Rearranging the equation, we have L^2 - 3L - 180 = 0. This is a quadratic equation that can be factored. Factoring, we have (L - 15)(L + 12) = 0. We can now solve for L by setting each factor equal to zero: L - 15 = 0 or L + 12 = 0. This gives us two possible solutions for L: L = 15 or L = -12.
Since we cannot have negative dimensions for a rectangle, we discard the negative solution. Therefore, the length of the rectangle is 15 feet. The width can be found by substituting this value back into the equation: Width = 15 - 3 = 12 feet. So, the dimensions of the rectangle are 15 feet by 12 feet.

Arsenic is a compound that occurs naturally in very low concentrations. Arsenic blood concentrations in healthy adults are Normally distributed with mean =3.2 micrograms per deciliter (ug/dl) and standard deviation sigma = 1.5. What is the range of arsenic blood concentrations corresponding to the middle 90% of healthy adults?
Answers
Answer:
0.7325 to 5.6675 ug/dl
Step-by-step explanation:
The middle 90% will be 45% above the mean and 45% below the mean. This means
0.5-0.45 = 0.05 and
0.5+0.45 = 0.95
We use a z table. Look in the cells; find the values as close to 0.05 and 0.95 as we can get.
For 0.05, we have 0.0505 and 0.0495; since these are equidistant from 0.05, we use the value between them. 0.0505 is z=-1.64 and 0.0495 is z=1.65; this gives us z=-1.645.
For 0.95, we have 0.9495 and 0.9505; since these are equidistant from 0.95, we use the value between them. 0.9495 is z = 1.64 and 0.9505 is z=1.65; this gives us z = 1.645.
Now we use our z score formula,
[tex]z=\frac{X-\mu}{\sigma}[/tex]
Our two z scores are 1.645 and -1.645; our mean, μ, is 3.2; and our standard deviation, σ, is 1.5:
[tex]1.645=\frac{X-3.2}{1.5}[/tex]
Multiply both sides by 1.5:
[tex]1.5(1.645)=\frac{X-3.2}{1.5}\times 1.5\\\\2.4675 = X-3.2[/tex]
Add 3.2 to each side:
2.4675+3.2 = X-3.2+3.2
5.6675 = X
[tex]-1.645=\frac{X-3.2}{1.5}[/tex]
Multiply both sides by 1.5:
[tex]1.5(-1.645)=\frac{X-3.2}{1.5}\times 1.5\\\\-2.4675=X-3.2[/tex]
Add 3.2 to each side:
-2.4675+3.2 = X-3.2+3.2
0.7325 = X
Our range is from 0.7325 to 5.6675.
Final answer:
The range of arsenic blood concentrations corresponding to the middle 90% of healthy adults is approximately 0.765 ug/dl to 4.035 ug/dl.
Explanation:
The middle 90% of a Normally distributed data set falls within approximately two standard deviations of the mean. In this case, the mean is 3.2 ug/dl and the standard deviation is 1.5. To find the range of arsenic blood concentrations corresponding to the middle 90% of healthy adults, we can calculate the upper and lower boundaries.
First, we need to find the Z-scores that correspond to the 5th and 95th percentiles. The Z-score formula is:
Z = (x - mu) / sigma
Applying the formula, we get:
Z_lower = (x_lower - 3.2) / 1.5 = -1.53
Z_upper = (x_upper - 3.2) / 1.5 = 1.53
Next, we need to find the corresponding x values. Rearranging the Z-score formula, we can solve for x:
x = Z * sigma + mu
Plugging in the Z scores, we have:
x_lower = -1.53 * 1.5 + 3.2 = 0.765
x_upper = 1.53 * 1.5 + 3.2 = 4.035
Therefore, the range of arsenic blood concentrations corresponding to the middle 90% of healthy adults is approximately 0.765 ug/dl to 4.035 ug/dl.
If price was $2.00 per gallon and decreased to $1.40 per gallon, how does quantity of gasoline demanded change?
Answers
The price and demand are inversely proportional to each other, When the price is less, the demand is higher. When the price is high, the demand is low.
So , as given, the gasoline prices has been decreased from $2.00 per gallon to $1.40 per gallon, so now the demand will increase. The quantity of gasoline that will be in demand will increase.
Answer:
The quantity of gasoline demanded will increase.
Step-by-step explanation:
We are asked to find the change in demand of gasoline, when price of gasoline decreased from $2 per gallon to $1.40.
We know that quantity of a product demanded is inversely proportional to supply of the product.
This means that an increase in price will decrease the quantity demanded, while a decrease in price will increase the demand.
Since the price of gasoline is decreased by $0.60 per gallon, therefore, the quantity of gasoline demanded will increase.

The area of a property in square meters, measures 704/5. A house is built that occupies 5/6 of the total area. Half of the remaining area is used to build a terrace, how much area is left to build?
we know that
The total area represent the fraction 6/6
A house represent the fraction 5/6 of the total area
The remaining area represent the fraction (6/6)-(5/6)=1/6 of the total area
If half of the remaining area is used to build a terrace
then
the area of the terrace represent the fraction (1/6)/2=1/12 of the total area

11/6 or decimal 1.8333... + 4.9 = 6.733333....
Step-by-step explanation:
Simplify the following:
(3 + 2/3)/2
Express 4/6 in its lowest form by cancelling out gcd(4, 6) = 2 from the numerator and denominator. 4/6 = (2×2)/(2×3) = 2/3:
(2/3 + 3)/2
Put 3 + 2/3 over the common denominator 3. 3 + 2/3 = (3×3)/3 + 2/3:
((3×3)/3 + 2/3)/2
3×3 = 9:
(9/3 + 2/3)/2
9/3 + 2/3 = (9 + 2)/3:
((9 + 2)/3)/2
9 + 2 = 11:
(11/3)/2
11/3×1/2 = 11/(3×2):
11/(3×2)
3×2 = 6:

HERE'S HOW TO DO IT :)
A composite figure is made up of several simple geometric figures such as triangles, rectangles, squares, circles, and semicircles.
To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.
(SEE EXAMPLE ATTACHED)
HERES WHAT WE KNOW ABOUT COMPOSITE FIGURES:
Composite Figures. A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). For example, figure ABCD is a composite figure as it consists of two basic figures

ANSWER
a. 216
EXPLANATION
The given function is;
[tex]f(x) = {6}^{x} [/tex]
We want to find the value of this function when x=3.
We substitute this value into the function to obtain,
[tex]f(3) = {6}^{3} [/tex]
[tex]f(3) = 6 \times 6 \times 6[/tex]
[tex]f(3) = 216[/tex]
Answer:
The correct answer is option a. 216
Step-by-step explanation:
It is given that,
f(x) = 6ˣ for x = 3
To find the value of f(x)
f(x) = 6ˣ
when x = 3 we can write,
f(3) = 6³ = 6 * 6 * 6 = 216
Therefore the value of f(x) when x = 3 is 216
The correct answer is option a. 216
The imaginary number i is equal to
−1
, which expression is equivalent to −(4 + 3i) + (2 + 2i)?
A) 2 + 2i
B) 2 − i
C) −2 + i
D) −2 − i
Answers
Answer:
D
Step-by-step explanation:
An equivalent expression is an expression which is equal to −(4 + 3i) + (2 + 2i). You can expand or simplify an expression to make an equivalent expression. Combine like terms - constants with constants and imaginary with imaginary - to simplify.
−(4 + 3i) + (2 + 2i) = -4 + 2 -3i + 2i = -2 - i
