Answer:
-9A · √(5yA)
Step-by-step explanation:
The coefficient -3 stays the same.
45 factors into 5·9, which is helpful because 9 is a perfect square.
Thus, √45 = 3√5.
y cannot be factored. It stays under the radical.
A³ can be factored into A² (a perfect square) and A.
Thus,
-3√(45yA³) = -3 · 3√5 · √y · A · √A, or
= (-3)(3)(A) · √(5yA), or
= -9A · √(5yA)
Answer:
<em>0.6 ÷ 0.3 - Option 2.</em>
<em>0.2 × 0.9 - Option 3.</em>
Answer:
The answer is "Option a, Option b, and Option d".
Step-by-step explanation:
In the given question it is used to stratifying the sampling if the population of this scenario it flights takes off when it is divided via some strata.
-
In option a, In this case, it stratified the sampling, as the population of planes taking off has been divided into the days of the week.
-
In option b, It also used as the case of stratified sampling.
-
In options c, it is systematic sampling, that's why it is wrong.
-
In option d, It is an example of stratifying the sampling.
Answer:
Step-by-step explanation:
First, you should put the axis of symetry as 5, -7 because f(x)= (x-h)^2+k and h is 5 and k is -7. the axis of symetry is x=5 because that is the "folding point" of the graph. Next, you would have to plug In 4 and 6 as your helping points to tell you where the other points of the function are going to be.
Plug 4 in and you get -6. plug 6 in and you get -6. plot the points (4, -6) and (6,-6).
Hope this helps!
