Answer:
9 cm
Step-by-step explanation:
Since PQ and RS are opposite each other, then in a parallelogram, the lengths will be congruent.
Therefore 2x+5=4x+1
2x=4
x=2
If you plug x=2 into the the original equation, you get 9 cm.
The measure of PQ is 9 centimeters.
Important information:
In parallelogram \(PQSR, PQ=(2x+5),RS=(4x+1)\)Parallelogram:The oppositie sides of a parallelogram are equal.
\(PQ=RS\)
\(2x+5=4x+1\)
\(5-1=4x-2x\)
\(4=2x\)
Divide both sides by 2.
\(2=x\)
Now, find the measure of PQ.
\(PQ=2x+5\)
\(PQ=2(2)+5\)
\(PQ=4+5\)
\(PQ=9\)
Therefore, the measure of PQ is 9 centimeters.

Hope this helps!!!
Please give me brainliest!!
Have a GREAT day and remember to take care of yourself!
The required trigonometric function is cos x.
Given that cosec x cot x \((1-cos^{2}x )\).
By using trigonometric identities \(cos^{2}x + sin^2x=1\),
that gives \(1-cos^2x=sin^2x\). -----(1)
By using the trigonometric functions,
cosec x = \(\frac{1}{sin x}\) -------(2)
cot x = \(\frac{cos x}{sin x}\) -----------(3)
By substituting equation 1, 2 and 3 in the given expression,
That implies, cosec x cot x \(sin^{2}x\) = \(\frac{1}{sin x}\) × \(\frac{cos x}{sin x}\) × \(sin^2 x\)
On algebraic simplifying gives,
cosec x cot x \(sin^{2}x\) = \(\frac{cos x}{sin^2 x}\) × \(sin^2 x\)
On simplifying trigonometric functions gives,
cosec x cot x \(sin^{2}x\) = cos x.
Hence, the required trigonometric function is cos x.

Wendy traveled 12 miles to school in 20 minutes. What was her speed in
miles per hour?
Answer:
36 mph.
Step-by-step explanation:
Speed is a rate. It can be represented as the distance traveled/the time spent traveling.
\(s=d/t\)
In this problem, we know the distance and the time. All that needs to be done is some conversion and then plugging in.
In the problem, we know that Wendy travels 12 miles in 20 minutes. But to get her speed in miles per hour, we need to convert 20 minutes into hours.
To do this, let's set up a quick proportion. Let's call the number of hours in 20 minutes x.
I\(\frac{20minutes}{xhours}=\frac{60 minutes}{1 hour}\)
If there are 60 minutes in an hour, then there are 20 minutes in 1/3 of an hour.
Now we can plug 1/3 hours in.
\(s=\frac{12}{1/3}\)
This is the same as saying
\(s=12*3\)

There are four critical paths in a network. A-B-C-D-E, A-F-E, A-B-H-J-K-E and A-S-T-E. Each activity in this network can be crashed by a maximum of 6 weeks. The crashing cost (per week), for the first week, for activity A is: $540, E is $545 and all other activities is : $135 (per week per activity). The crashing cost, second week and onwards, for activity A is $1080 per week, E is $1350 per week and for all other activities is $405 per activity per week. You have a maximum crashing budget of $2300. The maximum possible reduction in the project duration will be: a. 4 weeks b. 2 weeks c. 5 weeks d. 1 week e. 3 weeks
After analyzing all the critical paths the maximum possible reduction in the project duration is 1 week. The correct option is d. 1 week.
To determine the maximum possible reduction in the project duration within the given budget, we need to analyze the critical paths and crashing costs.
The crashing cost per week for activity A is $540 in the first week and $1080 per week from the second week onwards. For activity E, it is $545 in the first week and $1350 per week thereafter. For all other activities, the crashing cost is $135 per activity per week in the first week and $405 per activity per week thereafter.
Considering the crashing budget of $2300, let's calculate the maximum reduction for each critical path:
A-B-C-D-E: The total crashing cost for this path is $1350 (for A and E) + $405 (for B, C, and D) = $1755 per week. With a budget of $2300, this path can be crashed for a maximum of $2300 / $1755 = 1.31 weeks. Therefore, the maximum reduction for this path is 1 week.
A-F-E: The total crashing cost for this path is $1350 (for E) + $405 (for F) = $1755 per week. With the given budget, this path can be crashed for a maximum of $2300 / $1755 = 1.31 weeks. Hence, the maximum reduction for this path is 1 week.
A-B-H-J-K-E: The total crashing cost for this path is $1350 (for A and E) + $810 (for B, H, J, and K) = $2160 per week. This path can be crashed for a maximum of $2300 / $2160 = 1.06 weeks. Thus, the maximum reduction for this path is 1 week.
A-S-T-E: The total crashing cost for this path is $1350 (for A and E) + $540 (for S and T) = $1890 per week. This path can be crashed for a maximum of $2300 / $1890 = 1.22 weeks. Hence, the maximum reduction for this path is 1 week.
After analyzing all the critical paths, we observe that the maximum possible reduction in the project duration is 1 week.
The correct option is d. 1 week.

choose the equation that represtents the graph
The equation that represents the graph is y = -(2/3)x + 6 .
The X- intercept is defined as the point at which the line crosses the x axis.
The Y- intercept is defined as the point at which the line crosses the y axis.
When a and b are the x and y intercept of a line then
the equation of line in intercept form is x/a + y/b = 1 .
Form the graph in the question
we can see that the graph crosses the x axis at 9, so it's x intercept is 9.
and the graph crosses the y axis at 6, so it's y intercept is 6.
So the intercept form of the line will be given by
x/9 + y/6 = 1
taking LCM of 6 and 9 as 18 ,
and solving further we get ,
2x/18 + 3y/18 = 1
(2x + 3y)/18 = 1
2x + 3y = 18
3y = 18 - 2x
Dividing both sides by 3 , we get
y = 18/3 - (2/3)x
y = 6 - (2/3)x
y = -(2/3)x + 6
Therefore , the equation that represents that represents the graph is y = -(2/3)x + 6 .

Solve y'' + 16y = 0, y(π/8) = -1, y'(π/8) = 4
y(t) = ____
The solution to the differential equation is y(t) = -1/4 cos(4t) - sin(4t).
What is the solution to the differential equation?The characteristic equation is r^2 + 16 = 0, which has solutions r = ±4i. Thus the general solution to the differential equation is
y(t) = c1 cos(4t) + c2 sin(4t).
Using the initial conditions, we have
y(π/8) = c1 cos(π/2) + c2 sin(π/2) = c2 = -1,
and
y'(t) = -4c1 sin(4t) + 4c2 cos(4t),
so
y'(π/8) = -4c1 sin(π/2) + 4c2 cos(π/2) = 4c2 = 4.
Thus, c2 = -1 and c1 = -1/4, so the solution to the differential equation is
y(t) = -1/4 cos(4t) - sin(4t).

at a financial services company, the mean percent allocation for bonds in a retirement portfolio is 26.9 percent with a population standard deviation of 3.6 percent. a random sample of 35 retirement plan participants was taken and the probability that the mean bond percent for the sample will be at least 28 percent was determined. was the probability a left-tail, right -tail or interval probability? what is the probability that the mean bond percent for the sample will be at least 28 percent? select all that apply below. select the two correct answers that apply below. you may use a calculator or the portion of the z-table given below. round your answer to three decimal places if necessary.
The probability in question is a right-tail probability because it is asking for the probability that the mean bond percent for the sample will be at least 28 percent, which is greater than the mean of 26.9 percent.
To calculate the probability, first find the z-score:
z = (sample mean - population mean) / (population standard deviation / sqrt(sample size))
z =\( (28 - 26.9) / (3.6 / sqrt(35))\)
z = \( 1.1 / (3.6 / 5.916)\)
z =\( 1.1 / 0.608\)
z ≈ \( 1.809\)
Using the z-table, the area to the left of this z-score is 0.965. Since we are looking for the right-tail probability, we need to subtract this value from 1:
Probability = 1 - 0.965
Probability ≈ 0.035
Thus, the probability that the mean bond percent for the sample will be at least 28 percent is approximately 0.035. The correct answers are right-tail probability and 0.035.

The probability of A is 0.50, the probability of B is 0.45, and the probability of either (i.e. P(A?B)
is 0.80. What is the probability of both A and B?
The probability of both A and B occurring is 0.15.
The probability of both A and B occurring can be found using the formula P(A∩B) = P(A) + P(B) - P(A∪B), where P(A∩B) is the probability of both A and B occurring, P(A) is the probability of A occurring, P(B) is the probability of B occurring, and P(A∪B) is the probability of either A or B occurring.
Plugging in the given values, we get:
P(A∩B) = 0.50 + 0.45 - 0.80
P(A∩B) = 0.95 - 0.80
P(A∩B) = 0.15

Answer:
To find the value of a4, we need to use the recursive formula for the sequence. The formula gives us the nth term in the sequence in terms of the (n-1)th term.
We are given that a1 = -7, so we can use the recursive formula to find a2, a3, and a4:
a2 = a1 - 4 = -7 - 4 = -11
a3 = a2 - 4 = -11 - 4 = -15
a4 = a3 - 4 = -15 - 4 = -19
Therefore, the value of a4 is -19.
