Answer:
I don't know the number of the ratio but i will create an example of 3 ways to write ratio
Let's use the number 10:8
you can write it like
- 10:8 (colon)
- 10 to 8
- 10/8 ( a fraction)
The Phase Shift is how far the function is shifted horizontally from the usual position.
As points, x-intercepts take the form
, so to find the intercepts we can set
and solve for
.
From the first equation alone, we already know that
is a solution, which means one intercept is
.
The second equation gives
so that the second intercept occurs at
.
So if
and
, we have
, giving C as the answer.
Answer:
C
Step-by-step explanation:
Answer:
Option D is not a rational number
Step-by-step explanation:
A rational number is one that can be represented in the form of fraction like X/Y, where X and Y are integers and X ≠ 0. While an irrational number is one that cannot be expressed in the form of simple fractions.
For example, ¾ is a rational number while √3 is an irrational number.
Now to the question;
A) The product of 2 and 0.3333 gives;
2 × 0.3333 = 0.6666.
This can be expressed as a fraction as; 6666/10000.
Thus it is a rational number
B) The sum of 2 + √3 and 5 - √3 gives;
2 + √3 + 5 - √3 = 7
As a fraction, it can be written as; 7/1
Thus it is a rational number.
C) The sum of 37 and 12 is;
37 + 12 = 49
Can be expressed as; 49/1
Thus,it's a rational number.
D) Product of 2 and √2 gives;
2 × √2 = 2√2
It can't be expressed as a fraction with integers. Thus, it's not a rational number.
