Answer:
i dont get it the are no answer choices nor are there numbers lolololol
Step-by-step explanation:
To find the range, you need to locate the vertex:
equation for vertex = ax^2 + bx +c
in x^2 + 3, a = 1, b = 0 and c = 3
now vertex form = a(x+d)^2 +e
d = b/2a = 0/2*1 = 0
e = c-b^2/4a = 3-0^2/4*1 = 3
The equation becomes: (x+0)^2 +3.
The range is Y ≥ 3 ( greater than or equal to 3)
Answer:
x = 1.47 or x = -7.47
Step-by-step explanation:
x²+6x+9=20
This is a quadratic equation
x²+6x+9-20=0
x²+6x-11=0
Step 1 : Write the quadratic formula
x = <u>-b±√b²-4(a)(c)</u>
2a
Step 2 : Substitute values in the formula
a = 1
b = 6
c = -11
x = <u>-6±√6²-4(1)(-11)</u>
2(1)
x = <u>-6±√80</u>
2
x = -3 + 2√5 or x = -3 - 2√5
x = 1.47 or x = -7.47

A. Probability: 1/6
Since there are 6 possibilities and we are looking for one out of six of those possibilities, we get the ratio or fraction of 1/6
b. The wording on this question is very awkward.
c. The probability that you do not roll a six is 5/6. This is because again, there are 6 possibilities, but we are looking cases where it is not one possibility. There are 5 cases, therefore the answer is 5/6.
