If a(x) = 3x + 1 and b(x)= VX-4, what is the domain of (bºa)(x)?
0 (-0,00)
0 (0.00)
O [1,00)
O [4,00)
The domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex].
How to apply composition between functions
The composition of two functions consists in replacing the variable of the former function ([tex]b(x)[/tex]) by the latter function ([tex]a(x)[/tex]). If we know that [tex]b(x) = \sqrt{x-4}[/tex] and [tex]a(x) = 3\cdot x +1[/tex], then the composite function:
[tex]b\,\circ\,a \,(x) = \sqrt{(3\cdot x+1)-4}[/tex]
[tex]b\,\circ\,a\,(x) = \sqrt{3\cdot x-3}[/tex] (1)
Since the composite function is a square root function, then the domain fulfill the following inequation:
[tex]3\cdot x -3 \ge 0[/tex]
[tex]x \ge 1[/tex]
Hence, the domain of [tex]b\,\circ \,a\,(x)[/tex] is [tex][1, +\infty)[/tex]. [tex]\blacksquare[/tex]

A die is rolled. The set of equally likely outcomes is {1, 2, 3, 4, 5, 6}. Find the probability of getting a 9.
Answer:
you are only rolling 1 dice the probability of getting 9 is 0 there are only 6 sides to one die
Probability of getting a 9 is 0
Give that;
Total number of outcome in die = 6
Total numbers are {1, 2, 3, 4, 5, 6}
Find:
Probability of getting a 9
Computation:
Number of outcome 9 come in a die = 0
So,
[tex]Probability = \frac{Number\ of\ favourable\ outcomes}{Total\ outcomes}[/tex]
Probability of getting a 9 = 0 / 6
Probability of getting a 9 = 0

The list shows the numbers of each type of pie baked at a bakery today.
• 13 apple
• 4 pecan
• 3 pumpkin
What percentage of the pies baked today were NOT apple?
The percentage of pies baked that were not apple was 33.33 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The number of apple pies baked at the bakery = 13
The number of pecan pies baked at the bakery = 4
The number of pumpkin pies baked at the bakery = 3
So ,
Total number of pies baked at the bakery =
Number of apple pies baked at the bakery + Number of pecan pies baked at the bakery + Number of pumpkin pies baked at the bakery
Total number of pies baked at the bakery = 13 + 4 + 3
= 21
Now ,
The number of pies that were not apple = Number of pumpkin pies baked at the bakery + Number of pecan pies baked at the bakery
The number of pies that were not apple = 4 + 3
= 7
And ,
The percentage of pies that were not apple =
( The number of pies that were not apple / Total number of pies baked at the bakery ) x 100 %
The percentage of pies that were not apple = ( 7 / 21 ) x 100 %
= ( 1 / 3 ) x 100 %
= 33.33 %
Hence , the percentage of pies that were not apple is 33.33 %

Write the equation of the line that has a slope of ½ and a y-intercept of -2.
Answer (assuming it can be in slope-intercept form):
[tex]y = \frac{1}{2}x-2[/tex]
Step-by-step explanation:
When knowing the slope of a line and its y-intercept, you can write the line's equation in slope-intercept form, or y = mx + b format. To write a full equation, substitute the m and the b for real values.
The m represents the slope of the line. Thus, substitute [tex]\frac{1}{2}[/tex] for m. The b represents the y-intercept. Thus, substitute -2 for b. This gives us the following equation and answer:
[tex]y = \frac{1}{2}x -2[/tex]
