Answer: The form for an exponential equation is f(t)=P0(1+r)t/h where P0 is the initial value, t is the time variable, r is the rate and h is the number needed to ensure the units of t match up with the rate. Plug in the initial value for P and the rate for r. You will have f(t)=1,000(1.03)t/h.

The quadrilateral is a trapezoid. What is the value of x?454825
The value of x for the trapezoid quadrilateral is equal to 5.
The quadrilateral is an isosceles trapezoid, with a line parallel to both opposing lines splitting the other two unparallelly going lines into equal halves. Hence, according to normal relations, the mid length is 5x-1.
The lengths of the opposing sides are 21 and 27 respectively. As a result, we may write 2(5x - 1) = 21 + 27.
Growing further, 10x - 2 = 48
10x = 48 + 2
10x = 50
Divide all sides by ten.
x = 50/10
x = 5
As a result, the value of x is 5.

Which is an equivalent expression for 18c+144
?
Responses
An equivalent expression for 18c+144 is 18(c+8), by factoring out the greatest common factor of the terms 18 and 144.
In the original expression 18c + 144, we have two terms that do not have any common factors other than 1. However, we can see that both terms are multiples of 18, with 18 as the greatest common factor. So, we can factor out the 18 to simplify the expression.
To factor out 18, we divide each term by 18, which gives us:
18c/18 + 144/18
The first term simplifies to c, and the second term simplifies to 8, so we have:
c + 8
This expression represents the sum of c and 8, and it is equivalent to 18c + 144. However, we can still simplify this expression further by factoring out the common factor of c + 8, which gives us:
c + 8 = 18(c + 8)
So, we have the equivalent expression 18(c + 8), which is the original expression 18c + 144 after factoring out the greatest common factor of 18.

At the start of a party, a drink dispenser contains 912 quarts of iced tea. After the party only 7 cups of tea remain. How many cups of iced tea did people drink during the party?
Amount of iced-tea consumed during party was 92 cups, which is equivalent to 23 quarts. It's important to note difference between volume units such as cups and quarts, and the conversion factor between them.
To determine the number of cups of iced-tea that were consumed during the party, we need to subtract the amount that remained from the total amount that was in the drink dispenser at the start of the party.
One cup of iced tea is equal to 1/16 of a quart, so 7 cups is equal to
7 * (1/16) = 7/16 quarts.
Thus, the total amount of iced tea that was consumed during the party is 912 quarts -
7/16 quarts = 912 - 7/16
= 912 - 7 * (1/16)
= (912 * 16 - 7 * 1) / 16
= 1476 / 16
= 92.25 cups, rounded down to the nearest whole number, which is 92 cups.
It is important to note that the answer is given in cups and not quarts. Quarts is a unit of volume and cups is a unit of volume as well, but they are not equivalent. 1 quart is equal to 4 cups. If we wanted to express the amount of iced tea consumed in quarts, we would multiply the answer by 1/4.
In conclusion, the number of cups of iced tea consumed during the party is 92 cups, and if we express this in quarts it is equivalent to
92 * (1/4) = 23 quarts.

a research company is claiming that 75% of college students shop online. jamila takes a sample of 200 college students and finds that 120 college students shop online. which type of inference test should jamila use?
Since the research company is making a claim about the proportion of college students who shop online and Jamila is taking a sample of college students to test this claim, she should use a one-proportion z-test.
A one-proportion z-test is used to test whether the proportion of successes in a sample is significantly different from a hypothesized proportion. Here, the hypothesized proportion is 75% (the claim made by the research company) and the sample proportion is 120/200 = 0.6.
Jamila can use the one-proportion z-test to determine whether the difference between the sample proportion and the hypothesized proportion is statistically significant. The null hypothesis is that the sample proportion is equal to the hypothesized proportion (i.e., p = 0.75), and the alternative hypothesis is that the sample proportion is not equal to the hypothesized proportion (i.e., p ≠ 0.75).
Based on the sample size and the fact that the population standard deviation is not known, Jamila should use the normal approximation to the binomial distribution to perform the one-proportion z-test.

Given sin(-t) = 2/3, find csc (t).
Answer:
csc(t) = -3/2
Step-by-step explanation:
Given sin(-t) = 2/3, we can find the value of csc(t) as follows:
sin(-t) = 2/3
sin(t) = -2/3 (since the sine function is an odd function)
Since csc(t) = 1/sin(t), we have:
csc(t) = 1/sin(t) = 1/(-2/3) = -3/2
Answer:
[tex]\displaystyle \csc(t)=-\frac{3}{2}[/tex]
Step-by-step explanation:
[tex]\displaystyle \sin(-t)=\frac{2}{3}\\\\\sin(t)=-\frac{2}{3}\\ \\\frac{1}{\sin(t)}=\frac{1}{-\frac{2}{3}}\\\\\\\csc(t)=-\frac{3}{2}[/tex]
The second step can be done because sin(-t) is an odd function.
a rectangular bedroom is 5 ft longer than it is wide. its area is 84 ft2. what is the width of the room?
The width of the bedroom is approximately 7.32 feet.
A rectangle is a four-sided figure with opposite sides being equal and parallel. The area of a rectangle is given by multiplying the length and width of the rectangle.
Let's assume that the width of the bedroom is 'x' feet. We know that the length of the room is 5 feet longer than its width. Therefore, the length of the room will be (x+5) feet.
Now, we can use the given area of the bedroom to set up an equation:
Area of rectangle = Length x Width
84 = (x+5) x x
Simplifying this equation, we get:
84 = x² + 5x
Rearranging, we get:
x² + 5x - 84 = 0
This is a quadratic equation that can be solved using the quadratic formula:
x = (-b ± √(b² - 4ac))/2a
In this case, a = 1, b = 5 and c = -84. Substituting these values in the formula, we get:
x = (-5 ± √(5² - 4(1)(-84)))/2(1)
Simplifying this, we get:
x = (-5 ± √721)/2
We can ignore the negative root since the width of the bedroom cannot be negative. Therefore, the width of the bedroom is:
x = (-5 + √721)/2
x ≈ 7.32 feet

Tractor Position Expression

Scooter Position
Expression
The expressions, in terms of t, for each vehicle so that the vehicles start separated and meet at 10 seconds is:
Tractor's position = Vt * t
Scooter's position = Vs * t
What is the expression?Let's assume that the starting point for both the tractor and the scooter is at "0". We can then write the expressions for their positions in terms of time "t" as follows:
For the tractor:
Tractor's speed = Vt
Tractor's position = Vt * t
For the scooter:
Scooter's speed = Vs
Scooter's position = Vs * t
Now, as both the vehicles meet at 10 seconds, we can write the equation:
Vt * 10 = Vs * 10
The above equation represents the position of both the vehicles at 10 seconds. If we assume the speed of the tractor and the scooter to be constant, then the equation gives us the relationship between their speeds.

A sample size of 44 is needed to assure with 95% confidence that the sample mean will not differ from the population mean by more than 2.5 units.
To find the sample size needed to assure with 95% confidence that the sample mean will not differ from the population mean by more than 2.5 units, we can use the formula:
n = [ (z * σ) / E ]^2
where n is the required sample size, z is the critical value for the desired confidence level (95% confidence level corresponds to a z-value of 1.96), σ is the population standard deviation (given as the square root of the variance, which is √(70) ≈ 8.37), and E is the maximum error, or the maximum difference between the sample mean and population mean that we are willing to tolerate (which is given as 2.5 units).
Substituting the given values into the formula, we get:
n = [ (1.96 * 8.37) / 2.5 ]^2
n ≈ 43.48
Rounding up to the nearest whole number, we get a required sample size of n = 44.
