I'm pretty sure that this is how it goes
If ƒ(x ) = x^2 + 1, find ƒ(a + 1).
x=(a+1) so u replace x to get this:
f(a+1) = (a+1)^2+1
If you square "a" it just becomes a^2 and "1" squared is just "1"
1+1=2
Answer: a^2+2a+2
So scientific notation is making the number manageable.
scientific notation is
(a number >1 and <10) times 10^x
we count how many places the decimal has to move to make the number >1 and >10.
the answer is 6.
5.74 times 10^6
Answer:
x = 63.4
Step-by-step explanation:
Here, we want to find the value of x
To do this , we use the appropriate trigonometric ratio
The side facing x is 12, this is called the opposite
6 is the third side and it is called the adjacent
The trigonometric identity that links both is tan
Tan is the ratio of the opposite to the adjacent
Thus,
tan x = 12/6
tan x = 2
x = tan^-1 (2)
x = 63.4
Answer:
(-20)+(-2)
Step-by-step explanation:
(-14) - 8 = -22
(-20) + (-2) = -22
The common ratio (R) is -3.
-2 times -3 is 6.
6 times -3 is -18.
-18 times -3 is 54.
R=-3.
This is a geometric sequence.
