Answer:
3
Step-by-step explanation:
So to answer this question we need to see what it is actually telling us and not telling us.
*4 feet tall
*75 percent taller
They aren't telling us how tall it is now.
To solve this problem, multiply 4x75%
That will give you 3.
The bush is 3 feet tall now.
Answer:
3.36
Step-by-step explanation:
3+12%=3.36
Answer:
Below.
Step-by-step explanation:
f(x) = a(x - j)^2 + k is the standard vertex form where (j, k) is the vertex,
f(x) = (x + 3)^2 + 4
Comparing this to the standard form we see that:
vertex = (-3, 4)
Answer:
15+2i
Step-by-step explanation:
Hi there!
We are given the following expression:
(7-4i) + (8+6i)
And we want to write it as a complex number in standard form
Standard form is <u>a+bi</u>, where a is the real part of the number and bi is the imaginary part of the number.
We can open up the parentheses on the expression
7-4i+8+6i
Now combine the like terms (add 8 and 7 together, then add -4i and 6i together)
<u>15+2i </u>
The complex number is now in standard form
Hope this helps!
Answer: Cos, Cosine
Step-by-step explanation:
You can use SOH CAH TOA to help you find out whether you are using Sine, Cosine or Tangent.
SOH- The 'S' is for Sine, then the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH- The 'C' is for Cosine, the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA- The 'T' is for Tangent, then the 'O' and the 'A' is for Opposite over Adjacent.
As you have the Adjacent (the side next to the angle you are looking for) and Hypotenuse (the side opposite the right angle), you would be using Cosine.
I haven't answered it because I read this as though you wanted the explanation. If you do want an answer just let me know then I can edit my answer.
Hope this helps :)
