Answer:
f(g(-1)) = 22
g(f(-1))=6
Step-by-step explanation:
We are given
[tex]f(x)=5x+2 \\g(x)=3-x[/tex]
We need to find f(g(-1)) and g(f(-1))
Finding f(g(-1))
First we will find f(g(x)) i.e
[tex]f(g(x))=5(3-x)+2\\f(g(x))=15-5x+2\\f(g(x))=-5x+17[/tex]
Now finding f(g(-1)) by putting x=-1
[tex]f(g(x))=-5x+17\\Put \ x=-1\\f(g(-1))=-5(-1)+17\\f(g(-1))=5+17\\f(g(-1))=22[/tex]
So, f(g(-1)) = 22
Finding g(f(-1))
First we will find g(f(x)) i.e
[tex]g(f(x))=3-(5x+2)\\g(f(x))=3-5x-2\\g(f(x))=-5x+1[/tex]
Now finding g(f(-1)) by putting x=-1
[tex]g(f(x))=-5x+1\\Put \ x = -1\\g(f(-1))=-5(-1)+1\\g(f(-1))=5+1\\g(f(-1))=6[/tex]
So, g(f(-1))=6

A. 0.04
B. 0.16
C. 0.47
D. 0.84
Answer:
Probability = 0.04 (Approx)
Step-by-step explanation:

High school diploma = 0.03
Total holder = 0.03+0.44+0.26+0.11 = 0.84
Find:
Probability
Computation:
Probability = 0.03 / 0.84
Probability = 0.0357
Probability = 0.04 (Approx)
If f x) = [x – 3], find f (5.6 ).
Answer:
2.6
Step-by-step explanation:
We have the function f (x) = [x – 3]
We need to inster the value required which is 5.6
f (5.6) = [5.6 – 3]=
5.6-3 =2.6
f (5.6)=2.6

Answer:
7-5 => 2-7+5 => -2-7-5 => -127-(-5) => 12Step-by-step explanation:
Lets solve the expressions one by one
1. 7-5
we can see that it is simple subtraction. A smaller number is being subtracted from a large number.
So the answer is 2
2. -7+5
There are two numbers with different signs. When there is a number with plus and a number with minus both quantities are subtracted but the larger quantity determines the sign of the answer.
In this case, 7 is larger and has negative sign, the answer will be -2
3. -7-5
When there are two numbers with minus sign they are added but the answer has the minus sign with it.
So the answer will be: -12
4. 7-(-5)
When minus is multiplied with minus it converts to positive
So
[tex]= 7-(-5) = 7+5 = 12[/tex]
Hence,
7-5 => 2-7+5 => -2-7-5 => -127-(-5) => 12A store is offering a discount on shorts of 23.4%.The original price of the shirt is $13.24.how much will you have to pay the clerk

Ricardo ran the 60-meter sprint in 5 seconds. Which best represents Ricardo’s rate in meters per second?
Answer:
1.8 or less
Step-by-step explanation:
girls 1.8 or less
Ricardo’s rate in meters per second is equivalent to 12 meters per second.
What is rate of change?Rate is defined as the rate of change of one variable with respect to other variable.{r} = dy/dx
In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that Ricardo ran the 60-meter sprint in 5 s.
Ricardo’s rate in meters per second
r = d/t
r = 60/5
r = 12
Therefore, Ricardo’s rate in meters per second is equivalent to 12 meters per second.

A chemist has 100 ml of 25% acid solution. how much of the solution does she need to drain and replace with 70% acid solution to obtain 100 ml of 60% acid solution?
Answer:
The proportion of acid at 70% that the chemist must use will be 77.8%, while the remaining 22.2% will be acid at 25%.
Step-by-step explanation:
Since the chemist has 100 ml of solution with 25% acid, and wants to obtain a solution of 60% acid by mixing the first with another 70% acid solution, to determine how much of each solution the chemical should use necessary to perform the following calculation:
70 x 1 + 25 x 0 = 70
70 x 0.9 + 25 x 0.1 = 65.5
70 x 0.8 + 25 x 0.2 = 61
70 x 0.7 + 25 x 0.3 = 56.5
Therefore, the proportion to be used is between 70% and 80% of acid at 70%, and 20% to 30% of acid at 25%.
70 x 0.75 + 25 x 0.25 = 58.75
70 x 0.76 + 25 x 0.24 = 59.2
70 x 0.77 + 25 x 0.23 = 59.65
70 x 0.78 + 25 x 0.22 = 60.1
Thus, the proportion should be between 77 and 78% of acid at 70% and 22 and 23% of acid at 25%.
70 x 0.778 + 25 x 0.222 = 60.01
Thus, finally, the proportion of acid at 70% that the chemist must use will be 77.8%, while the remaining 22.2% will be acid at 25%.
