-k + 0.03 + 1.01k = -2.45 - 1.81k
Multiplying through by 100, we have
-100k + 3 + 101k = -245 - 181k
Answer:
C
Step-by-step explanation:
Wrong answers and why:
A: it Is bigger than 180°
B: 180° is a straight line this one isn't straight
D: 150° Is too small
So C is the right answer
8n-28
4(2n-7)
you cant factor this. There are no powers
Solution:
we have been asked to write the given function in vertex form
As we know that the vertex form is
So Re-write the P(x) in the above form
So we have
vertically stretch the graph by a factor of 8
Shift the parent function Up by 128 units.
Shift parent function left by 4 units.
The first statement comes about because
a could be (say) 5
b could be (say) 6
Then c would be square root of 25 + 36 = 61 which is irrational.
I'm not sure of the wording of the second one. It reads like (5 + 6)^2 = 121 the two rationals added together make a rational number in my example. So I think that part is wrong. the second part is correct. For example sqrt(5) + sqrt(6) doesn't produce anything that is rational.
It doesn't have to. pi^2 + [cube root(10)]^2 does not produce anything rational and that is certainly not a perfect square. My first example shows that as well
I think the last one might be true.
