Answer:
A = 27π cm² or about 84.8 cm²
Step-by-step explanation:
Area of a full circle is πR²
As there are four right angles making up a 360° turn, and the missing piece is one of those four, there are ¾ of a circle remaing
A = ¾πR² = ¾π6² = 27π cm² or about 84.8 cm²
Given that a polynomial function P(x) has rational coefficients.
Two roots are already given which are i and 7+8i,
Now we have to find two additional roots of P(x)=0
Given roots i and 7+8i are complex roots and we know that complex roots always occur in conjugate pairs so that means conjugate of given roots will also be the roots.
conjugate of a+bi is given by a-bi
So using that logic, conjugate of i is i
also conjugate of 7+8i is 7-8i
Hence final answer for the remaining roots are (-i) and (7-8i).
Answer:
Oliver completed his training work in 50.25 hours
Step-by-step explanation:
we know that
we have
<u><em>Convert days to hours</em></u>
<u><em>Convert minutes to hour</em></u>
so
therefore
Oliver completed his training work in 50.25 hours
Given that Lana received 18 ounces of candy and Tom received 4 times as much candy as Lana received, then the number of candy Tom received is given by 4(18) = 72.
Now, given that Tom divided his candy evenly into 9 piles. Then the number of ounces of candy in each of Tom's piles is given by:
72/9 = 8 ounces.
Step-by-step explanation:
Breadth = 8m
Length = 8m + 4m = 12m
Area of the rectangle = length × breadth, 12m × 8m = 96m square.
