Answer:
what this basicaly means is that we have to multiply 3 by every thing inside the parethese
3*2x=6x
3*1=3
6x+3
Hope This Helps!!!
Answer:
-8.5
Step-by-step explanation:
If I'm not mistaken this is true because the opposite of a whole number (That isn't 0) is always the negative
Answer:
1. a pH value of 0 is at (0.1, 0) and a pH value of 1 is at (0.01, 1)
2. -0.7
3. f(x+1)
Step-by-step explanation:
For 1 and 2 you can just use a graphing calculator like Desmos.
For 3, this type of change would move the whole logarithmic function left, across the y-intercept, like what the question is asking for
Answer:
14.69 ft.
Step-by-step explanation:
Area of a square:
A=
Given:
A=221
Solve:
221=
=
a is approx. equal to 14.87 ft.
which is 14.69 ft.
If we call the leg of the small triangle y, and the leg perpendicular to x z, we can apply Pythagoras 3 times:
(1) 4 + y^2 = x^2
(2) x^2 + z^2 = 196 => z^2 = 196-x^2
(3) y^2 + 144 = z^2 => y^2 = z^2 - 144
Now fill in (3) in (1):
4 + z^2 - 144 = x^2
and then (2) in (1):
196-x^2-140 = x^2 => 2x^2 = 56 => x = √28 = 2√7
Answer C!
