Answer:
Step-by-step explanation:
We can do this a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15
This trinomial factors into
y = (x - 5)(x + 3)
from which
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15
Answer
x intercepts: (-3,0),(5,0)y intercept: (0,-15)The graph is below.
Solve for x.

Step-by-step explanation:
hypotunes isnt involved(as the length inst given and we know it is hypotunes as it is the oppisite direction from the right angle)
so sohcahtoa
therefore ir toa
tan(x)=o/a
(tan inverse)tan^-1=34/54
oppisite= 34 as it is oppisite to teh angle your trying to find
and the adjacent is beetwen the right angle and the angle your mesuring
The angle x is 32.2° which is opposite to the side perpendicular of the length 34.
Right angled triangle:
A right angle triangle have one angle as right angle, the side opposite to the right angle is called hypotenuse and the side on which angle 90 degree is created is called base. The third side is called perpendicular.
Here we have given that
Perpendicular = CD = 34
Base = BC = 54
If we apply tan on this triangle we will find the relation between angle B, CD and BC.
How to use tan into right angle triangle?we know that
tan x = [tex]\frac{perpendicular}{base}[/tex]
Using tan into our given triangle we have
[tex]tanx=\frac{CD}{BC}[/tex]
[tex]tanx=\frac{34}{54}[/tex]
[tex]tanx=0.629629[/tex]
[tex]x=tan^-1(0.629629)\\\\x=32.2[/tex]
Hence the final answer is 32.2°

Marcus plants daffodils in 6/10 of his garden and sunflowers in 11/100 of his garden. Which addition equation shows how to find the total fraction of the garden in which Marcus planted daffodils and sunflowers.
Answer:
71/100 of Marcus' garden is daffodils and sunflowers.
Step-by-step explanation:
To add fractions, the denominators need to be equal. So, 6/10 -> 60/100. 60+11=71, keep the 100. 71/100. Hope this helps!
A company makes 5 blue cars for every 3 white cars it makes. If the company makes 15 white cars in one day, how many blue cars will it make?
Answer:
25
Step-by-step explanation:
25, because 3 times what is 15, 5. So multiply 5 by 5 and get 25.
Answer:
25
The set-up would go something like this:
3 * x = 15
x is our variable that isn't defined, bur by doing some simple math we can determine that "x" is 5 becuase of simple logic and reasoning.
This means that you would also have to multiple the 5 by the 5 as well since we know that for every 3 white cars there is 6l5 blue cars.
this would bring the total to 25z hope this helped :)

A circle has a radius of 10 mm. What is its circumference?
Answer: 20pi mm
Step-by-step explanation:
The circumference of a circle is 2*pi*radius.
Therefore, the circumference is 2*pi*10mm = 20pi mm
Answer/s:
≈ 62.83 mm or 20π mm
Step-by-step explanation:
We can use the following formula to solve:
C = 2πr
C = 2π(10)
C ≈ 62.83 mm
-> You can also end up at 20π if you need an "exact" answer

Answer:
1
Step-by-step explanation:
3x + 5 = 8
Subtract 5 from both sides of the equation
3x + 5 -5 = 8 -5
Simplify
3x =3
Divide both sides of the equation by the same term
3x/3 = 3/3
Simplify
x = 1
Hence, 1 will make the equation True.

and on time
B. 40% of all the flights were on airline A
C. 40% of all flights were on time
D. 40% of A’s flights were on
The 0.4 in the yellow cell represents the relative frequency of flights that were on time for Airline A.
Option A is the correct answer.
What is a relative frequency?A Relative frequency is a statistical measure that represents the proportion or percentage of a certain category or value in relation to a given set of data.
It is calculated by dividing the frequency of a particular category by the total number of observations in the data set.
We have,
Looking at the table, we can see that the column for Airline A has a total relative frequency of 0.6, which means that 60% of all flights were operated by Airline A.
However, the question asks specifically about the percentage of flights that were on time for Airline A, which is given as 0.4 or 40% in the table.
Thus,
The 0.4 in the yellow cell represents the relative frequency of flights that were on time for Airline A.

B. Experimentation, Tolerance, Dependence, Addiction
C. Tolerance, Addiction, Social Use, Experimentation
D. Experimentation, Addiction, Tolerance, Recovery
Answer:
D. Experimentation, Addiction, Tolerance, Recovery
Explanation:
First all the drug addicts try the drug, also refereed as experimentation.
Then they soon get addicted to it because it contains harmful substances attracting it and cannot control themselves.
Then tolerance which means, endure pain and resist from taking the drug.
Then the person gradually recovers and starts living off without the drug.
