It starts down on the left and goes up on the right and intersects the x-axis at x = −1, 1, and 3.
Which statement best describes the graph?
We want to describe the graph of:
[tex]y = x^3 - 3x^2 - x + 3[/tex]
We can see that the y-intercept is y = 3, and the x-intercepts can be seen in the graph below, these are at: x = -1, x = 1 and x = 3.
We also can see that it is cubic, so it starts down.
Then the correct option is the second one:
"It starts down on the left and goes up on the right and intersects the x-axis at x = −1, 1, and 3."

David is making his own strawberry yogurt. In his mixture, the number of strawberries is proportional to the amount of milk in cups david uses 2 1/2cups of milk for every 14 strawberries. If david uses 203 strawberries, how much milk will he need?
Answers
X α Y where X represents the number of strawberries and Y represents the number of cups of milk
To get rid of the proportionality sign, we introduce a proportionality constant k. We calculate this by using the initial conditions given.
X = kY
at X = 14 strawberries Y = 2 1/2 cups of milk = 5/2 cups
14 = k(5/2)
k = 28/5
At X = 203
X = kY
203 = 28/5 (Y)
Y = 145/4 or 36 1/4 cups of milk needed
How do i take the square root of a number?
Answers
Final answer:
To take the square root of a number, use the square root function on a calculator or raise the number to the power of 0.5. For higher roots, like fourth roots, raise to the power of 0.25, or take the square root twice. Adjust exponentials before taking roots and estimate if a calculator is not available.
Explanation:
To take the square root of a number, you can perform this operation either by using a calculator or through manual calculations. If you're using a calculator, simply use the square root function, which is usually represented by a radical sign (√) or sometimes as a button labeled 'sqrt'. However, when dealing with equations or expressions where the variable is raised to a power, such as , you will need to take the fourth root to solve for T. This is equivalent to raising the number to the 0.25 power (since 1/4 is equivalent to the fourth root). You can verify this method by checking that the square root of a number is the same as that number raised to the 0.5 power.
In case you are working with exponentials, remember to adjust the exponent so it's evenly divisible by 2 before extracting the square root. If the number is written in scientific notation, extract the square root of the coefficient and halve the exponent. For example, taking the square root of 1 x 104 would be 1 x 102 since the square root of 1 is 1 and half of 4 is 2.
When you lack a calculator, estimating roots, such as cube roots or higher, can be done with a rough mental approximation. For instance, to find the cube root of 87, you know that the cube root of 64 (which is 4) is too small and the cube root of 125 (which is 5) is too big, so you can start by guessing around 4.3. With trial, error, and adjustments, you can find a more accurate result.

What is the equation of the blue graph?
Answers
a) plug in 1 for x. Since G(1)=-3 (because of the point given, (1,-3) ), we can determine that C is the only function that fits the criteria.
b) You can also think about it in terms of shifting. If you have an equation like this, or if you are finding the center of a circle or anything with a similar equation, (x-x1)^2 gives you (in this scenario) the x value of the vertex of the parabola (x1). It's where x=x1 so when you subtract x1 you get 0. Now, if you see the answers A and D given, and you see (x+1)^2, think of it like (x-(-1))^2. Since the vertex of this parabola is at x=1 and not x=-1, you can automatically rule out those two options.
G(x) = (x - 1)² - 3
This form of a quadratic equation is attained by 'completing the square';
This form tells us the coordinates of the vertex of a quadratic, i.e. the sole turning/stationary point or the highest/lowest point of the quadratic graph;
In general, for any quadratic that you complete the square with, you will get:
(x + a)² + b, for which the vertex is (-a, b).
In the case of G(x), we can see from the graph that the vertex (lowest point) is: (1, -3)
Therefore the completed the square form of the equation we want is going to be: (x - 1)² - 3.

For these graphs, just look at whether the direction of the line from its origin (the small circle part) is going up the number line to the larger numbers or towards the smaller (more negative) numbers;
In this case, the line starts at 10 and goes up the number line;
The circle that denotes the start of the line is unshaded, this means the inequality being represented is a > or <, not a ≥ or ≤, which is shown by a circle that is shaded;
Looking at the line (representing x-values) therefore, we can determine the inequality it represents is:
x > 10;
so now we just need to rearrange the options given and see which is the same as x > 10;
In this case it is option A:
x/5 - 6 > -4
x/5 > 2
x > 10

20 = 10/3L
20 * 3/10 = L
60/10 = L
6 = L <=== length
W = 2/3L
W = 2/3(6)
W = 12/3
W = 4 <=== width
The dimensions of her rectangular flower bed will be 4 feet by 6 feet.
What is the perimeter of the rectangle?Let W be the rectangle's width and L its length.
The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be
Perimeter of the rectangle = 2(L + W) units

Identify the 25th term of the arithmetic sequence 2,1 (3 / 5), 1 ( 1 / 5) ... (2 points)
Answers
a(n)=a+d(n-1), a=initial value, d=common difference, n=term number.
The common difference is the constant difference found by subtracting the previous term from any term. In this case:
d=2-1 3/5=1 3/5-1 1/5=-2/5=-0.4 and we can easily see that the first term is 2 so
a(n)=2-0.4(n-1) which can be simplified...
a(n)=2-0.4n+0.4
a(n)=2.4-0.4n, so the 25th term is:
a(25)=2.4-0.4(25)
a(25)= -7.6 or if you prefer...
a(25)= -7 3/5
The 25th term of the arithmetic sequence is -31.6.
Looking at the sequence:
- First term [tex]\( a_1 = 2 \)[/tex]
- Second term [tex]\( a_2 = 1 \left( \frac{3}{5} \right) = \frac{3}{5} \)[/tex]
- Third term [tex]\( a_3 = 1 \left( \frac{1}{5} \right) = \frac{1}{5} \)[/tex]
Calculate the common difference d:
[tex]\[ d = a_2 - a_1 = \frac{3}{5} - 2 = \frac{3}{5} - \frac{10}{5} = -\frac{7}{5} \][/tex]
Now that we have [tex]\( d = -\frac{7}{5} \)[/tex], we can find the general term [tex]\( a_n \)[/tex] of the arithmetic sequence:
[tex]\[ a_n = a_1 + (n-1)d \][/tex]
Substitute [tex]\( a_1 = 2 \)[/tex] and [tex]\( d = -\frac{7}{5} \)[/tex]:
[tex]\[ a_n = 2 + (n-1) \left( -\frac{7}{5} \right) \]\[ a_n = 2 - \frac{7(n-1)}{5} \]\[ a_n = 2 - \frac{7n - 7}{5} \]\[ a_n = \frac{10 - 7n + 7}{5} \]\[ a_n = \frac{17 - 7n}{5} \][/tex]
Now, find [tex]\( a_{25} \)[/tex]:
[tex]\[ a_{25} = \frac{17 - 7 \cdot 25}{5} \]\[ a_{25} = \frac{17 - 175}{5} \]\[ a_{25} = \frac{-158}{5} \]\[ a_{25} = -31.6 \][/tex]
Help please?? If you deposit $750 in an account that pays 8% annual interest compounded continuously, what will the balance be after five years?
Answers
A=p e^rt
A the balance?
P present value 750
E constant
R interest rate 0.08
T time 5 years
A=750×e^(0.08×5)
A=1,118.87
The balance in your account after five years will be approximately $1,118.85.
Step 1: Understand Continuous Compounding
In continuous compounding, interest is earned not only on the initial principal amount but also on the accumulated interest over time. This means interest is calculated continuously throughout the year, leading to a slightly higher final balance compared to simple interest.
Step 2: Formula for Continuous Compounding
The formula for continuous compounding to find the future value (balance) after t years is:
A = P * e^(r*t)
where:
A = Final amount (balance after t years)P = Principal amount (initial deposit - $750)e = Euler's number (approximately 2.71828)r = Annual interest rate (as a decimal - convert 8% to 0.08)t = Time in years (5 years)Step 3: Apply the Formula
Now that we have the formula and values, let's plug them in:A = $750 * e^(0.08 * 5)Step 4: Calculate the Final Balance
You can use a calculator to evaluate the expression.
A ≈ $750 * e^(0.4) ≈ $750 * 1.4918
Step 5: Round the Answer (Optional)
Depending on the desired level of precision, you can round the answer to two decimal places:
A ≈ $1118.85 (rounded to two decimal places)

Answer:
(A) 5.5 units
Step-by-step explanation:
Given: Diameter AC intersects chord BD at point E such that AE = 2.5 units and DE = 3.4 units. Point O is the center of the circle, and the radius of the circle is 5 units. we have to find the approximate length of BE.
Now, CE=CO+OE=5+(OA-AE)=5+2.5=7.5 units.
Now, by Intersecting Chord Theorem which states that when two chords intersect each other inside a circle then the products of their segments are equal.
Thus, [tex]CE{\times}AE=BE{\times}DE[/tex]
Substituting the given values, we get
[tex]7.5{\times}2.5=3.4{\times}DE[/tex]
[tex]\frac{7.5{\times}2.5}{3.4}=DE[/tex]

Step-by-step explanation:
Abel and Zöe’s grandparents opened a savings account for an equal amount upon the birth of each child. Now, the values of their accounts could be found by the following expressions, where t represents the years since 2011.
Abel: y = 1266.77(1.03)^t

To find the difference in children's ages first we take ratio of 1266.77/1159.26
Ratio of 1266.77/1159.26= 1.09
now we write ratio in terms of powers of 1.03
1.03^t = 1.09
Take ln on both sides
t ln(1.03) = ln(1.09)
Divide both sides by ln(1.03)

Aly is looking for a new car. She has test-driven two cars but can only purchase one. The probability that she will purchase car A is 0.47 and the probability that she will purchase car B is 0.35. What is the probability that she will not purchase either car A or car B? 0.12 0.41 0.82 0.18
Answers
P(B) = 0.35
The probability of an event occurring ranges from 0 to 1, or 0 to 100%.
P(not A or not B) would be the complement of the events occurring.
The probability of an event and its complement is always 1.
Ex. P(A) + P(A') = 1
P(A) + P(B) = 0.47 + .35 = 0.82
P(not A or not B) = 1 - 0.82 = 0.18
Last option
The probability that Aly won't purchase either car A or car B is 0.18. This is calculated by subtracting the combined probability of purchasing either car from 1.
Explanation:The question pertains to the concept of probability, which can be defined as a measure of the likelihood that a given event will occur. In this case, Aly is deciding between two cars to purchase (Car A and Car B). The probability that she will purchase car A is 0.47 and the probability that she will purchase car B is 0.35. These probabilities might have been estimated based on Aly's preferences, past behavior, or other relevant factors.
Since probabilities add up to 1, we can calculate the probability that Aly won't purchase either car A or car B by subtracting the sum of the probabilities of buying car A and car B from 1. So, we do 1 - (0.47 + 0.35) = 0.18. Therefore, the probability that she will not purchase either car A or car B is 0.18.

The Cool Company determines that the supply function for its basic air conditioning unit is S(p) = 40 + 0.008p3 and that its demand function is D(p) = 200 - 0.16p2, where p is the price. Determine the price for which the supply equals the demand.
Answers
We are given the functions:
S (p) = 40 + 0.008 p^3 ---> 1
D (p) = 200 – 0.16 p^2 ---> 2
T o find for the price in which the price of supply equals demand, all we have to do is to equate the two equations, equation 1 and 2, and calculate for the value of p, therefore:
S (p) = D (p)
40 + 0.008 p^3 = 200 – 0.16 p^2
0.008 p^3 + 0.16 p^2 = 160
p^3 + 20 p^2 = 20,000
p^3 + 20 p^2 – 20,000 = 0
Calculating for the roots using the calculator gives us:
p = 21.86, -20.93±21.84i
Since price cannot be imaginary therefore:
p = 21.86
Three-Fourths of the student body attended the pep-rally. If there were 1230 students at the pep rally, how many students are there in all?
Answers
3/4x = 1230
x = 1230 * 4/3
x = 4920/3
x = 1640 <=== total students
To find the total number of students, set up a proportion and solve for x. The total number of students is 1640.
Explanation:To find the total number of students, we can set up a proportion using the information given. If three-fourths of the student body attended the pep-rally, that means three-fourths of the total number of students is equal to 1230. Let's let x represent the total number of students. Then, we can write the proportion as:
3/4 = 1230/x
Now, to solve for x, we can cross multiply:
3x = 4 x 1230
Dividing both sides by 3:
x = 4 x 1230 / 3
Calculating the expression on the right side of the equation:
x = 4920 / 3
Finally, divide 4920 by 3 to get:
x = 1640
So, there are 1640 students in total.
