The polynomial function y = x^3 -3x^2 + 16x - 48 has only one non-repeated x-intercept. What do you know about the complex zeros of the function?
Answer: B
Step-by-step explanation:
x³ - 3x² + 16x - 48 = 0
→ x²(x - 3) + 16(x - 3) = 0
→ (x² + 16) (x - 3) = 0
→ (x² - (-16)) (x - 3) = 0
→ (x - 4i)(x + 4i)(x - 3) = 0
→ x - 4i = 0 x + 4i = 0 x - 3 = 0
→ x = 4i x = -4i x = 3

A candy bar has 220 calories 132 calories are sugar what percent of the calories does the candy bar have?
What are the answer choices?
To find out what percent of the calories in a candy bar comes from sugar, divide the calories from sugar (132) by the total calories (220) and multiply by 100, resulting in 60% of the calories being from sugar.
To calculate what percent of the calories in the candy bar are from sugar, we can use the formula for percentage: (part / whole) x100. In this case, the part is the number of calories from sugar, and the whole is the total number of calories in the candy bar.
First, let's identify the given values:
Now, let's calculate the percentage:
Percentage of calories from sugar = (132 / 220) x 100Calculating this, we find:
Percentage of calories from sugar = 0.6 x100Percentage of calories from sugar = 60%Therefore, 60% of the calories in the candy bar are from sugar.

Carl rode a horse about 15 f ode a horse about 15 feet from the center of the car om the center of the carousel. Allison r ousel. Allison rode a horse about 10 f a horse about 10 feet from the center om the center. How much fur . How much further did Carl' ther did Carl's horse s horse travel in one complete turn of the carousel?
Carl's horse traveled approximately 31.4 feet further than Allison's horse in one complete turn of the carousel. The distances were calculated using the circumference formula for each horse based on their distance from the centre of the carousel.
Explanation:The question involves comparing the distances traveled by horses on a carousel based on their distance from the center of the ride. To find out how much further Carl's horse traveled compared to Allison's, we need to calculate the circumference of the circular paths each horse took during one complete turn of the carousel and then find the difference between these two distances.
To calculate the circumference (C) of a circle, we use the formula C = 2πr, where π (pi) is approximately 3.14159 and r is the radius of the circle, in this case, the distance from the center of the carousel to the horse.
For Carl's horse:
CCarl = 2π(15 feet) ≈ 2π×15 ≈ 94.2 feet
For Allison's horse:
CAllison = 2π(10 feet) ≈ 2π×10 ≈ 62.8 feet
The difference in the distances traveled by the horses in one complete turn is CCarl - CAllison, which is approximately 94.2 feet - 62.8 feet = 31.4 feet. Therefore, Carl's horse travelled about 31.4 feet further than Allison's horse in one complete turn.

Shelly is trying to improve her running time for a track race she ran the first race in 43.13 seconds her time was 43.1 seconds in the third race of this pattern continues what will Shelly time will be inthe fourth race
Answer:
The time in the fourth race is 43.04 seconds.Step-by-step explanation:
Shelly's first race time is 43.13 seconds.
Shelly's second race times is 43.1 seconds.
Basically, she improved 0.03 seconds, because 43.13 - 43.1 = 0.03.
If she keeps this patterns that means she will improve 0.03 each race.
So, the third race times is 43.1 - 0.03 = 43.07 seconds.
The fourth race time is 43.07 - 0.03 = 43.04 seconds.
Therefore, the time in the fourth race is 43.04 seconds, because she's improving at a constant rate of 0.03 seconds per race.
Mr. Ramirez receives 4 sets of books each set has 16 fiction books and 14 nonfiction books he puts 97 books in his lilbarry and donates the rest how many books does he donate
Mr. Ramirez donates 23 books.
Explanation:To find the number of books that Mr. Ramirez donates, we first need to calculate the total number of books he receives. Since each set has 16 fiction books and 14 nonfiction books and he receives 4 sets, the total number of books he receives is 4 sets * (16 fiction books + 14 nonfiction books) = 4 * (16 + 14) = 4 * 30 = 120 books.
Since Mr. Ramirez puts 97 books in his library, he donates the remaining books. To find the number of books he donates, we subtract the number of books he keeps from the total number of books he receives: 120 books - 97 books = 23 books.
Therefore, Mr. Ramirez donates 23 books.

Saul simplifies the expression 2x3 + 4x3 to 6x6. Use the drop-down menus to complete the statements below to explain why Saul's solution is correct or incorrect.
Answer:
Saul is incorrect. The proper answer should be 6x^3
Step-by-step explanation:
Think of "x^3" as "x". So we have 2x+4x = 6x. Similarly, 2x^3+4x^3 = 6x^3. The exponents of the like terms do not change.
As a more real world example, let's say that we replace "x^3" with "dogs". Saying "2x^3" could mean "2 dogs". Same goes for "4x^3" meaning "4 dogs". So "2x^3+4x^3" turns into "2 dogs + 4 dogs", and you can see that leading to 6 dogs total. The last step is to replace "dogs" with "x^3" to end up with 6x^3. The x^3 stays the same the whole time in much the same way that "dogs" do not change either.

Answer: Choice C)
y = (x-2)(x-2)
note: This is the same as y = (x-2)^2
======================================================
The x intercept or root is x = 2, so x-2 is a factor. There is only one root visible, but this is a parabola, so it's technically a double root (it repeats itself). That is why (x-2) shows up twice giving (x-2)(x-2)
If the equation was simply y = x-2, then it would be a linear equation instead of a curved parabola.
Note how plugging in x = 2 leads to the following y value
y = (x-2)(x-2)
y = (2-2)*(2-2)
y = 0*0
y = 0
So (2,0) is the only x intercept.

A biker rode 45 miles in 180 minutes. At what speed (in miles per hour) was the biker travelling? A. 4 B. 17 C. 9 D. 12
Answer:
v = 15 miles / hour
Step-by-step explanation:
Given:
Distance covered by biker = s=45 miles
time taken by him = t=180 minutes
TO Find:
speed in miles per hour = v = ?
Solution:
As it is given that the distance covered is 45 miles
and time taken by him is 180 minutes
as one hour have 60 minutes
so time taken by rider = t = 180 /60
= 3 hours
this step is done because we have to find speed in miles per hour
Now
The formula for finding the distance is
distance = speed * time
or
s = v * t
we have to find v
so dividing both sides by t
[tex]\frac{s}{t} = \frac{v*t}{t}[/tex]
it becomes
[tex]v = \frac{s}{t}[/tex]
Putting the values
[tex]v = \frac{45}{3}[/tex]
solving it gives
v = 15 miles / hour
which is the required speed
in the given options it is not available
The speed is 15 miles per hour, not matching any of the provided answer choices.
The question asks for the speed of the biker in miles per hour when given the distance rode over a certain amount of time. To find the speed, we can use the formula: Speed = Distance / Time.
In this case, the biker rode 45 miles in 180 minutes. Since there are 60 minutes in an hour, we first convert 180 minutes into hours by dividing by 60: 180 / 60 = 3 hours.
Next, we calculate the speed: Speed = 45 miles \/ 3 hours = 15 miles per hour. But since this isn't one of the options provided, it seems there has been a typo in the answer choices. The correct answer, which should be 15 mph, is missing in the options.

NOT ANSWERED^^^^^^^^^^^^^^^^^^^^^^^ Pls help
Answer:
7.11 and 9.48
Step-by-step explanation:
.12 is equal to 7.11
with out coupon
.12 is equal to 9.48
with the coupon
a. Isaac's total bill is $84.53
b. Isaac's price after the discount is $63.40
c. The shoe store clerk's commission before the coupon is $9.48 and $7.11 after the coupon
Solution to the first question
Total bill = cost of shoes + tax paid
Tax paid = tax rate + cost of shoes
Cost of shoes = $37.00 + $42.00. = $79
Tax paid = $79 + 0.07 = $5.53
Total bill = $5.53 + $79 = $84.53
Solution to the second question
The discounted price of the shoes can be found by subtracting the value of the discount from the price of the shoes
Discounted price = cost of the shoes = value of the 25% discount
Value of the 5% discount = 0.25 x $79= $19.75
Discounted price = $79 - $19.75 = 59.25
Bill = discounted price x ( 1 + tax rate)
59.25 x 1.07 = $63.40
Solution to the third question
Commission before the coupon
Commission = 12% x price before the coupon
0.12 x $79 = $9.48
Commission after the coupon
Commission = 12% x price after the coupon
0.12 x 59.25 = $7.11

Multiplying by a fraction gives a _____ number.
equal
smaller
larger
Multiplying by a fraction yields a smaller number if the fraction is less than 1, and a larger number if the fraction is greater than 1.
When multiplying by a fraction, the result depends on the fraction you're multiplying by. If the fraction is less than 1 (or what we refer to as a proper fraction where the numerator is less than the denominator), then the result is a smaller number than the original number you started with. For instance, multiplying 5 by 1/2 (which is a proper fraction) will yield 2.5, which is smaller than 5. However, if you multiply by a fraction greater than 1 (an improper fraction where the numerator is greater than the denominator), such as 5/3, the result will be a larger number. So, multiplying 5 by 5/3 will yield approximately 8.33, which is larger than 5.

We have two linear functions which intersect at a point. Linear functions are lines which are made of points that satisfy the function or relationship. This means at the intersection, this point (3,-1), both functions have values. An input of x=3 produces y=-1 in both functions.
Answer:
The correct option is 4.
Step-by-step explanation:
If the graph of a function represent in coordinate plane, then x-axis represents the domain of the function and y-axis represents the range of the function.
We have to find the input value that produces the same output value for the two functions on the graph.
From the given graph it is clear that the intersection point of both functions is at (3,-1).
At x=3 the output value of f(x) is -1.
At x=3 the output value of g(x) is -1.
It means both functions have same output -1 at x=3.
Therefore the correct option is 4.

Answer:
D)80,000; exponential function
Step-by-step explanation:
We are given that a town with a population of 10,000 doubles every 14 years
So, Initial Population = 10,000
Now we are given that what will the population be in 42 years
First determine how many times population will double : [tex]\frac{42}{14} = 3[/tex]
So, In 42 years it doubles three times .
Now Linear functions change at a constant rate per unit interval while An exponential function changes by a common ratio over equal intervals.
So, the given situation will be modeled by exponential function
So, Using exponential function : [tex]y=ab^x[/tex]
Where a is Initial Population = 10,000
b is rate of change
x = time = 3 times
So, the population will be in 42 years=[tex]10000 (2)^3[/tex]
=[tex]80000[/tex]
So, the population will be 80,000 after 42 years.
Thus Option D is correct.

What is P(A\text{ or }B)P(A or B), the probability that the garment Ivan chooses is either green or a pair of pants?
Answer:
P(A or B) = 2/3
Step-by-step explanation:
Blue Garments = 1 blue shirt, 1 blue hat, 1 blue pair of pants
Total blue garments = 3
Green garments= 1 green shirt, 1 green hat, 1 green pair of pants
Total green garments = 3
Total no. of garments = blue garments +green garments = 6
A = event that Ivan selects a green garment
P(A) = Favourable outcomes/Total no. of outcomes
P(A) = 3/6
B = event that Ivan chooses a pair of pants
P(B) = 2/6
We need to find P(A or B) = P(A∪B)
By formula, P(A∪B) = P(A)+P(B)-P(A∩B)
P(A∩B) = Probability that a green pair of pant is chosen = 1/6
P(A∪B) = 3/6+2/6-1/6
