Answer:
f(g(x)) = -1
Step-by-step explanation:
[tex]f(x) = \frac{1}{x} \\ \\ g(x) = x - 2 \\ \\ \implies \: f(g(x)) = \frac{1}{x - 2} \\ \\ \implies \: f(g(1)) = \frac{1}{1 - 2} \\ \\ \implies \: f(g(1)) = \frac{1}{ - 1} \\ \\ \implies \: f(g(1)) = - 1[/tex]

The length of side AI is?
The length side of IH is?
The area of the visible side of the model is?
Answer:
AI=3.25 IH= 4.2
Step-by-step explanation
The distance between C and D is 1.3 inches, the distance between E and F is 0.75 inches and the distance between G and H is 1.2 inches. This is true because the model says so. If you look closely together, this is equal to the distance between AI which is the length of AI. The answer would be 1.2+1.3+0.75=3.25. To find the length of side IH you do the same strategy, the distance between sides D and E is 4.8 inches, at the bottom is 9 inches of distance between side I and side F. 9-4.8 inches is equal to 4.2 inches. Therefore, the length of side AI is 3.25 inches and the length of side IH is 4.2 inches. If I am wrong please tell me for feedback, I also hoped that this has helped you in your learning :)
Answer:
Step-by-step explanation:
AI is 3.25
IH is 4.2
Area is 23.025
On a test that has a normal distribution, a score of 49 falls two standard deviations below the mean, and a score of 61 falls one standard deviation above the mean. Determine the mean of this test.
The mean of this test will be 57.
What is Standard Deviation and Mean?
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.
The mean can be used to get an overall idea, or picture, of the data set.
Let Mean be 'm'
and standard deviation= [tex]\sigma[/tex]
So, m-2[tex]\sigma[/tex]=49
and, m + [tex]\sigma[/tex]=61
Solving the above two equation we get
[tex]\sigma =4[/tex]
Now, m= 61-[tex]\sigma[/tex]
= 61-4
= 57
So , the mean of this test will be =57

The coordinates of point A when it is rotated about 180 degrees will be (7,-4).
What is coordinate geometry?A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Given that:-
Point A is shifted by an angle of 180 degrees about an origin.As it is turned 180 degrees from its initial position ( -7,4) just opposite side of the origin so the new coordinates of the point will be (4,-7).
Therefore the coordinates of point A when it is rotated about 180 degrees will be (7,-4).

NASA launches a rocket at t=0 seconds. Its height, in meters above sea-level, as a function of time is given by h(t)=-4.9t2+64t+136.
The rocket will reach its peak height of 345 meters above sea level at _____ second
Using the vertex of the quadratic equation, it is found that:
The rocket will reach its peak height of 345 meters above sea level at 6.53 seconds.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:

[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the equation is given by:
h(t) = -4.9t² + 64t + 136.
The coefficients are a = -4.9 < 0, b = 64, c = 136, hence the instant of the maximum height is given by, in seconds:

Answer:

Step-by-step explanation:
9! = 362 880
6! = 720
362 880 / 720 = 504 = 384 + 5!
Answer:
9!/6! would be (9 x 8 x 7 x 6 x 5 x 4 x 3 x 2) / (6 x 5 x 4 x 3 x 2), which is 504.
Step-by-step explanation:
A factorial, by definition, is the product of a given whole number and each positive whole number less than itself. A factorial is denoted by an exclamation point (n!), with n being the number you want to find the factorial of.
Ex. 2! = 2 x 1 (you can get rid of the x1 because it does nothing)

Answer:
4568 ft³
Step-by-step explanation:
You want the volume of the figure made from two rectangular prisms.
VolumeThe volume of the whole is the sum of the volumes of its parts. The volume of a rectangular prism is the product of its dimensions.
The horizontal prism is 7 ft high, 8 ft wide, and 45 ft long.
The vertical prism has a square base 8 ft on a side, and is 32 ft long.
The total volume is ...
V = horizontal volume + vertical volume
V = (7 ft)(8 ft)(45 ft) + (8 ft)²(32 ft) = 4568 ft³
The volume of the figure is 4568 ft³.
<95141404393>
The total volume of the figure is 4,568 ft³
How to find the volume?We can view this as two different rectangular prisms, remember that the volume of a rectangular prism is equal to the product between its dimensions.
For the one that is laid down, the volume is:
V = 7 ft*8 ft*45 ft
V = 2,520 ft³
For the other prism, the volume will be:
V' = 8ft*8ft*32ft = 2,048 ft³
Adding the two volumes we will get:
volume = 2,520 ft³ + 2,048 ft³ = 4,568 ft³
That is the total volume of the figure in cubic feet.

Answer:
[tex]\boxed{\bold{1}}[/tex]
Using Pedmas rule:
[tex]\dashrightarrow \sf \dfrac{17+6-6+6}{6+17}[/tex]
subtract: 6-6 = 0
[tex]\dashrightarrow \sf \dfrac{17+6}{23}[/tex]
simplify the following

the numerator and denominator cancels out
[tex]\dashrightarrow \sf 1[/tex]
Given statement:
17 + 6 - 6 + 6 divided by 6 + 17The phrase "divided by" means division. Therefore,
⇒ (17 + 6 - 6 + 6) ÷ (6 + 17)
⇒ (17 + 6) ÷ (6 + 17)
Recall: A number divided by itself is 1
⇒ 1
Therefore, 1 is the solution to the expression.

please help me with this
Answer:
2n + 2
Step-by-step explanation:
If the directions for this problem say to "Simplify" then what you will do is to combine like terms. This is an expression because there is no equal sign. If it had an equal sign (and more information) it could be solved.
Since it only an expression we simplify:
-n + (-3) + 3n + 5
= -n + 3n + (-3) + 5
= 2n + 2
Answer:
I believe that it is, 2n + 2.
Step-by-step explanation:
You add all the common factors ( sorry if its a wrong vocab word ) -
( {-3} + 5 ) and ( 3n + { -n } )
-3 + 5 would also be 5 - 3 = 2
3n + -n would be 3n - n = 2n so it would be,
2n + 2 or 2 + 2n.
