The perimeter of The triangle in terms of 'x' is 3x - 2 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the perimeter of any planar figure except a circle is the sum of the lengths of its sides.
Given, A triangle has sides of length x, x + 2, and x - 4.
Therefore, The perimeter of the triangle is,
= x + (x + 2) + (x - 4).
= x + x + 2 + x - 4.
= 3x - 2 units.

Use a sine function to graph a sound wave with period of 0.002 seconds and an amplitude of 5 cm. Find the frequency in hertz for the sound wave.
Answer:
500Hertz
Step-by-step explanation:
Using the formula for calculating frequency in terms of period expressed as;
f = 1/T
f is the frequency
T is the period
Given
T = 0.002seconds
Frequency f = 1/0.002
Frequency f = 500Hertz
Hence the frequency in hertz for the sound wave is 500Hertz

Hope it is helpful....The angle of elevation to the top of the Empire State Building in New York is found to be 11° from the ground at a distance of 5281 feet from the base of the building. Using this information, find the height of the Empire State Building in feet. Use the dimensions given in the diagram to give an equation and solve. Round two decimal places.
Answer:
The height of the building is of 1026.52 feet.
Step-by-step explanation:
This situation is modeled by a right triangle, in which the length of the opposite side to the angle of 11º is the height of the building, while the length of the adjacent side is of 5281 feet.
Tangent:
In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.
In this question:
[tex]\tan{(11)} = \frac{x}{5281}[/tex]
[tex]x = 5281*\tan{(11)}[/tex]
Using a calculator, we have that the tangent of 11 degrees is: 0.1944. Thus:
[tex]x = 5281*\tan{(11)} = 5281*0.1944 = 1026.52[/tex]
The height of the building is of 1026.52 feet.

The altitude of an airplane is decreasing at a rate of 40 feet per second. What is the change in altitude of the airplane over a period of 26 seconds?
Answer:
-1040 feet
Step-by-step explanation:
Since the altitude decreases at 40 feet per second, we can find the change in altitude by multiplying -40 by the number of seconds:
So, multiply -40 by 26:
-40(26)
= -1040
So, the change in altitude will be -1040 feet

Kim rolls a dice and flips a coin.
a) Calculate the probability that she
gets a 2 and a head.
b) Work out the probability that she
gets an even number and a tail.
What would b be
Answer:
a) 1 / 12
b) 1 / 4
Step-by-step explanation:
The events are independent since they do not affect each other. The total probability of two independent events is the product of the probabilities of the two events.
a) When rolling a die, there are 6 outcomes, the numbers 1 - 6. There is only 1 outcome where you can get a 2. Therefore, the probability of rolling a two is 1/6.
When flipping a coin, there are two ways it can land: heads or tails. And there is one outcome with heads. The probability of getting head would be 1 / 2.
To find the the total, you multiply the probabilities of the two events: 1 / 6 * 1 / 2 = 1 / 12
b) As stated before, when rolling a die, there are 6 outcomes, the numbers 1 - 6. There are 3 outcomes where she can roll an even number: the numbers 2, 4, or 6. So, the probability of rolling an even number is 3 / 6 or 1 / 2.
When flipping a coin, there are two ways it can land: heads or tails. And there is one outcome with tails. The probability of getting tails would be 1 / 2.
Now, you multiply the two probabilities to get the total probability: 1 / 2 * 1 / 2 = 1 / 4

(5a + 18) + (48 - a) + (8a - 30) = 180
5a + 18 + 48 - a + 8a - 30 = 180
5a - a + 8a + 18 + 48 - 30 = 180
12a + 36 = 180
12a = 180 - 36
12a = 144

What is the volume, in cubic m, of a rectangular prism with a height of 8m, a width of 9m, and a length of 19m?
Answer:
The volume of the prism is of 1368 cubic m.
Step-by-step explanation:
Volume of a rectangular prism:
The volume of a rectangular prism is the multiplication of the lengths of its dimensions.
In this question:
Dimensions of 8m, 9m and 19m. So
8*9*19 = 1368.
Dimensions in meters, so volume in cubic meters.
The volume of the prism is of 1368 cubic m.

A random sample of 100 observations produced a sample proportion of 0.25. An approximate 95% confidence interval for the population proportion p is between?
a. 0.165 and 0.335
b. 0.165 and 0.321
c. 0.179 and 0.321
d. 0.207 and 0.293
e. 0.152 and 0.348
Answer:
The confidence interval for the population proportion p is between ( 0.165 and 0.335 )
Hence, Option a) 0.165 and 0.335 is the correct answer.
Step-by-step explanation:
Given the data in the question;
sample size n = 100
sample proportion p₀ = 0.25
q₀ = 1 - p₀ = 1 - 0.25 = 0.75
confidence interval = 95%
First we calculate our Standard Error
Standard Error = √( ( p₀ × q₀ ) / n )
we substitute
Standard Error = √( ( 0.25 × 0.75 ) / 100 )
Standard Error = √( 0.1875 / 100 )
Standard Error = √0.001875
Standard Error = 0.0433
Now, For 95% confidence interval; z = 1.96
so confidence interval for the population proportion p will be;
⇒ p₀ ± ( z × Standard Error )
we substitute
⇒ 0.25 ± ( 1.96 × 0.0433 )
⇒ 0.25 ± 0.084868
⇒ ( 0.25 - 0.084868 ), (0.25 + 0.084868 )
⇒ ( 0.25 - 0.084868 ), (0.25 + 0.084868 )
⇒ ( 0.165, 0.335 )
Therefore, The confidence interval for the population proportion p is between ( 0.165 and 0.335 )
Hence, Option a) 0.165 and 0.335 is the correct answer.
