Answer:
Height of bigger square pyramid = 3.072 meter
Step-by-step explanation:
Using equivalent ratios to find the side of the bigger square prism
128:8 = 250:X
X = (250 x 8) ÷ 128 = 15.625
Volume of a square pyramid = a x a x h/3
Hence to evaluate the height
250 = 15.625 x 15.625 x h/3
H = 3.072 meters
Answer:
Step-by-step explanation:
10√3 (-7 - √5)
10√3 × -7 + 10√3 × -√5
-70√3 + 10√3 × -√5
-70√3 - 10√3√5
-70√3 -10√3 × 5
-70√3 - 10√15
hope that helps, God bless!
The exterior angles should be A & C
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).
