Answer:
a = 254.5 mm² ( if using accurate value of π)
a = 254.4 mm² (if using 3.14 as approximate value of π)
Step-by-step explanation:
a = πr²
a = π * 9²
a = π * 81
(note using π = 3.1415926536)
a = 254.4690049408
Rounded
a = 254.5 mm²
(a = 254.4 If using π = 3.14)
Hey there!!
Okay here is how you solve this... first you look for factors of 12 and 35... for example...
12m² - m - 35
<u>(4m - 7)(3m + 5)</u><u /> <---- This is the factored form!<u>
</u>m = 7/4 and -5/3
<u />
I hope this helps! ^__^
A)Plugging in our initial statement values of y = 16 when x = 10, we get:
16 = 10k
Divide each side by 10 to solve for k:
16/10=
k = 1.6
Solve the second part of the variation equation:
Because we have found our relationship constant k = 1.6, we form our new variation equation:
y = 1.6x
Since we were given that x, we have
y = 1.6()
y = 0
B)Plugging in our initial statement values of y = 1 when x = 15, we get:
1 = 15k
Divide each side by 15 to solve for k:
1/15
=15k
k = 0.066666666666667
B the answer is B
To create a survey you need a common entity linked to a unique feature
With B…he is able to create a table,draw a graph ,a pie chart and do so
