Answer:
<2 = 34degrees
Step-by-step explanation:
Find the diagram attached below:
First we need to get <1;
<1 + 74 = 180 (angle on a straight line)
<1 = 180 - 74
<1 = 106degrees
Also, <1 + <2 + 40 = 180 (sum of angle in a triangle)
106+<2 + 40 = 180
146 + <2 = 180
<2 = 180-146
<2 = 34degrees
The given function is:
x^2 - 1
We want to calculate the limit of this function as x approaches zero. To do so, we will use direct substitution.
We will substitute the x with 0 in the given function to calculate its limit as follows:
Limit as x approaches 0 = (x)^2 - 1 = -1
Therefore, the correct choice is:
-1
Answer:
it means that the 2 lines will never meet, and that there will be no point where 2 things are the same amount
Answer:
Length: 430
Width: 100
Step-by-step explanation:
Length : x
Width: x - 330
Area = 43000
Area = length * width
43000 = x (x - 330)
43000 = x² - 330x
x² - 330x - 43000 = 0
x² - 430x + 100x - 43000 = 0 // Doing factorization
x (x - 430) + 100 (x - 430) = 0
(x+100)(x-430) = 0
x + 100 = 0
x = -100 (Since the length can not be negative)
x - 430 = 0
x = 430(This is the length)
Width: x - 330 = 430 - 330 = 100
Proof : 430 * 100 = 43000
