Answer:
<u><em>h(x+2)= x² +5</em></u>
Step-by-step explanation:
h(x)= x² +5 -2x
h(x+2)= (x+2)² +5 - 2(x+2)
h(x+2)= x² +4x+4+5-4x-4
h(x+2)= x² +5
Answer:
Sample size is
Step-by-step explanation:
Given that,
Margin of error %
Confidence level %
Suppose, sample proportion
i.e.
We know that,
Margin of error
∴
squaring on both side,
∴
Hence, the sample size is,
Hence, the correct option is
Answer:
y = 26
Step-by-step explanation:
9 + 22 = x + y
9 + 22 = 31
31 = x + y
x = 5
31 = 5 + y
31 - 5 = 26
y = 26
isosceles triangle has its 2 side equals and thus 2 angles opposite to equal side are equal.
consider in a triangle ABC
AB = AC then Angle B = Angle C
so here given angle B = 36
so angle C = 36
now in a triangle sum of all 3 angles is 180
so
angle A + angle B +angle C = 180
angle A + 36 +36 = 180
angle A = 180 - 72 = 108
2)
in a right angle triangle one angle is 90. another one is given as 28
so we kNow sum of all 3 angles is 180
so
third angle + 90 + 28 = 180
third angle = 180 - 118 = 62
The best way to approach this problem is to look at the graph of the given function. Replace values of x from 1 to 24 to indicate the numbers of hours in a day. As seen on the graph, there is only one point where the port is at high tide. That would be at 1:00 am.
Looking at the graph, it would be safe for the boats to be in the port when the graph levels off at around 10 to 24. That's from 10 am to before 12 midnight. Then, they would have to stay away between 12 midnight to before 10 am.
