The values of x, angle XWY and angle X are 3, 30 degrees and 115 degrees respectively.
What are the values of x, angle X and angle XWY?Parallelogram is simply a quadrilateral with two pairs of parallel sides.
The opposite sides are equal in length.
The opposite angles of a parallelogram are equal.
Consecutive angles are supplementary angles to each other (that means they add up to 180 degrees)
From the diagram;
Side WV = 3x
Side XY = 9
Since, opposite sides are equal in length.
Side WV = side XY
Hence:
3x = 9
Solve for x
x = 9/3
x = 3
Angle V = 115 degree
Angle X = ?
Since the opposite angles of a parallelogram are equal.
Angle V = Angle X
Angle X = 115 degrees
Angle V = 115 degrees
Angle W = ?
Since consecutive angles are supplementary angles to each other (that means they add up to 180 degrees)
Angle W + 115 = 180
Angle W = 180 - 115
Angle W = 65 degree
From the diagram;
Angle VWY = 35 degree
Angle XWY = ?
Sum of angle VWY and XWY equals Angle W which is 65 degrees.
VWY + XWY = 65
35 + XWY = 65
XWY = 65 - 35
XWY = 30 degrees.
Therefore, value of x is 3, angle XWY = 30 degrees, and angle X = 115 degrees.

How many 4 digit number can be formed by using 1, 2, 3, and 4 which are divisible by 4?
Answers
There are 6 four-digit numbers that can be formed using the digits 1, 2, 3, and 4, which are divisible by 4. These numbers are 3214 and 4312. The answer is that there are 6 four-digit numbers that can be formed using the digits 1, 2, 3, and 4, which are divisible by 4.
To find the four-digit numbers that are divisible by 4, we need to consider the divisibility rule of 4. According to this rule, a number is divisible by 4 if its last two digits are divisible by 4.
Let's list the possible combinations of the last two digits:
- 12 is not divisible by 4.
- 14 is not divisible by 4.
- 21 is not divisible by 4.
- 23 is not divisible by 4.
- 32 is divisible by 4.
- 34 is not divisible by 4.
- 41 is not divisible by 4.
- 43 is divisible by 4.
Out of these combinations, only 32 and 43 have the last two digits divisible by 4. We can pair each of these two-digit numbers with the remaining two digits in any order to form a four-digit number.
For example, if we pair 32 with 1 and 4, we get the number 3214. Similarly, if we pair 43 with 1 and 2, we get the number 4312.
Therefore, the four-digit numbers that can be formed using 1, 2, 3, and 4, and are divisible by 4, are 3214 and 4312.

(a) Eliminate the parameter to find a Cartesian equation of the curve.
(b) Sketch the curve and indicate with an arrow the direction in which the curve is traced as the parameter increases.
Answers
(a) Simplifying this expression gives:
x = cos(theta) + cos(3theta)
Now we have eliminated the parameter and have a Cartesian equation for the curve.
(b) To indicate the direction in which the curve is traced, we can draw an arrow pointing counterclockwise along the curve.
We can first eliminate sec2(theta) by using the identity sec2(theta) = 1/cos2(theta). Substituting this into the equation for y gives:
y = 1/cos2(theta)
Next, we can use the double angle formula for cosine to write cos2(theta) = (1 + cos(2theta))/2. Substituting this into the equation for x gives:
x = 2 cos(theta) = 2 cos(theta) (1 + cos(2theta))/2
Simplifying this expression gives:
x = cos(theta) + cos(3theta)
Now we have eliminated the parameter and have a Cartesian equation for the curve.
To sketch the curve, we can use the fact that cos(theta) has a period of 2π and oscillates between -1 and 1, while cos(3theta) has a period of 2π/3 and oscillates between -1 and 1 as well. The sum of these two functions will create a new curve that repeats every 2π/3 radians.
Starting at theta = 0, the value of cos(theta) is 1 and the value of cos(3theta) is 1, so the initial point on the curve is (3, 1). As theta increases, the curve moves counterclockwise and oscillates between a maximum value of 3 + 1 = 4 and a minimum value of 3 - 1 = 2.
To indicate the direction in which the curve is traced, we can draw an arrow pointing counterclockwise along the curve.

Assume that when human resource managers are randomly selected, 63% say job applicants should follow up within two weeksif 30 human resource managers are randomly selected, find the probability that exactly 20 of them say job applicants should follow up within two weeks
Answers
Using the binomial probability distribution it is found that there is a 0.1402 = 14.02% probability that exactly 20 of them say job applicants should follow up within two weeks.
The binomial distribution is a probability distribution that summarizes the likelihood that a value will take one of two unbiased values below a given set of parameters or assumptions.
Let X be the binomial random variable with parameters n and p, in which "n" represents the number of managers randomly selected and "p" represents the probability that the chosen managers say job applicants should follow up within two weeks.
According to the question,
63% say job applicants should follow up within two weeks therefore p=0.63
30 human resource managers are selected, therefore n = 30
For a binomial distribution, the probability of "m" successes is :
P ( X = m ) = ^nCm (p)^m (1 - p)^n-m = n! / m! (n - m)! (p)^m (1 - p)^n-m
According to the question, we can compute the probability that exactly 20 of the 30 selected applicants say job applicants should follow up within two weeks as :
n = 30, p = 0.63, m = 20
P ( X = m ) = n! / m! (n - m)! (p)^m (1 - p)^n-m
Therefore, P ( X = 6 ) = 30! / 20! ( 30 - 20 )! ( 0.63 )^20 (1 - 0.63)^30 - 20
P ( X = 6 ) = 30! / 20! 10! ( 0.63 )^20 ( 0.37 )^10
= 30045015 * ( 0.63 )^20 ( 0.37 )^10
=0.1402 (rounded to 4 decimal places)
Therefore the probability is 0.1402

Use the Table of Integrals in the back of your textbook to evaluate the integral: sec?(4t) tan’(4t) dt V1 – tanʼ(4t) +C
Answers
The evaluated integral is (1/12)[sec(4t)tan(4t)]³ + C.
To evaluate the integral sec²(4t)tan²(4t) dt using the Table of Integrals in the back of your textbook, follow these steps:
1. Identify the integral: ∫sec²(4t)tan²(4t) dt
2. Check the Table of Integrals for any formula that can help us evaluate the given integral. The most relevant one is the integration of sec(t)tan(t), which is given by:
∫sec(t)tan(t) dt = sec(t) + C
3. To apply this formula to our integral, we first rewrite the given integral by factoring sec²(4t) and tan²(4t) as follows:
∫sec²(4t)tan²(4t) dt = ∫[sec(4t)tan(4t)] [sec(4t)tan(4t)] dt
Let u = sec(4t)tan(4t), then du = [4sec(4t)tan(4t) + 4sec³(4t)] dt
4. Now, we apply the substitution:
∫u² (1/4)du = (1/4)∫u² du
5. Integrate with respect to u:
(1/4)(u³/3) + C = (1/12)u³ + C
6. Substitute back the original expression of u:
(1/12)[sec(4t)tan(4t)]³ + C
So, the evaluated integral is (1/12)[sec(4t)tan(4t)]³ + C.
Evaluate the integral. (use c for the constant of integration.) \(4t 64\) −\(t2 dt\)

Write a number sentence using the

Answers
Caroline could use the distributive property to check her answer by writing the following number sentence: \(2(3 + 9) = 2(3) + 2(9) = 6 + 18 = 24\)
The distributive property states that \(a(b + c) = ab + ac\). In this case, we have \(2\) bowls (\(a\)) with \(3\) green grapes (\(b\)) and \(9\) red grapes (\(c\)) in each bowl. Applying the distributive property to Caroline's number sentence \(2(3 + 9)\), we get:
\(2(3) + 2(9)\)
Now, we can calculate the number of green and red grapes in total:
\(2(3) = 6\) (total green grapes)
\(2(9) = 18\) (total red grapes)
Then, add the total number of green and red grapes:
\(6 + 18 = 24\)
So, the number sentence using the distributive property that Caroline could use to check her answer is:
\(2(3) + 2(9) = 24\)
The number sentence shows that Caroline can distribute the number \(2\) to each term inside the parentheses and then add the resulting products to get the total number of grapes. This is a useful strategy for checking answers and ensuring that the distributive property is being applied correctly. In this case, Caroline's original number sentence and the distributive property version both show that there are \(24\) grapes in total, which confirms that her calculations are correct.
