250 = 5 x is the equation you can use
The number of elements in a set is the cardinal number of the set
Here the number starts from 1 and continues till 94. So there are 94 numbers. Thus, the cardinal number of the set (1,2,3....94) is 94. The cardinal number of an empty set is 0.
Answer:
An advantage of using observation is it gives you more details than assuming or modeling would.
A disadvantage is how long it takes to get your answer.
The sample is the students and the population is 10.
If 3 out of 10 students use social media then 30% of the schools population probably uses social media.
Step-by-step explanation:
Answer:
y = 4x + 5
To find the slope do :
<u>21 - (-3)</u>
4 -(-2)
That will equal :
<u>24</u> simplified : 4
6
Take your slope and one of the points and plug it into y = mx + b
That will look like: (21) = 4(4) + b
21 = 16 + b
Subtract 16 <u>-16 -16 </u>
on both sides
This is your y-int: 5 = b
Put the slope and y-int into the equation
And this is your answer: y = 4x + 5
Horizontal translations
Suppose that h> 0
To graph y = f (x + h), move the graph of h units to the left.
We have then:
g (x + 5) = (x + 5) 2 + 3 (x + 5) - 4
Rewriting we have:
f (x) = x ^ 2 + 10x + 25 + 3x + 15 - 4
f (x) = x ^ 2 + 13x + 36
Equaling zero we have:
x ^ 2 + 13x + 36 = 0
We look for the roots of the polynomial:
(x + 9) (x + 4) = 0
x1 = -9
x2 = -4
Answer:
The zeros of the new function are:
x1 = -9
x2 = -4
