Answer:
The value of A is 20
Step-by-step explanation:
To find the answer, note that all triangles have a interior degree measurement of 180. Set the sum of the angles equal to 180.
71x - 1 + 20x + 90 = 180
91x + 89 = 180
91x = 91
x = 1
Now we can use this in the A angle to find the value.
A = 20x
A = 20(1)
A = 20
Answer:
71th term is 141
Step-by-step explanation:

1 + (n - 1)*2 = 141 {Use distributive property}
1 + 2n - 2 = 141
2n - 1 = 141
2n = 141 + 1
2n = 142
n = 142/2
n = 71
Answer:2
Step-by-step explanation:
3940 centimeters
Each 100 centimeters is 1 meter
The true statement about the graph of the function f(x) = x3 - 2x2 + 4x – 8 is (B) The function has 1 real zero that occurs 1 time.
<h3>How to determine the true statement</h3>
The function of f(x) is represented as:

Differentiate the function f(x)

Calculate the minimum value using:

So, we have:


Substitute 2/3 in f'(x)


The value of f'(2/3) is greater than 0.
This means that the function f(x) has 1 real zero, and it occurs once at point (2,0)
Hence, the true statement is (b)
