First set 2n-1=4n+5 and solve for n. once you have n plug it back into each equation and then multiply those two together. Do the same to n-3 and 2n+1. Once you get the answer to both subtract them
Answer: XI = 10.35 mm
Step-by-step explanation:
Considering the given triangle XIF, to determine XI, we would apply the sine rule. It is expressed as
a/SinA = b/SinB = c/SinC
Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes
XI/SinF = XF/SinI = FI/SinX
The sum of the angles in a triangle is 180°. It means that
F + 63 + 52 = 180
F = 180 - (63 + 52)
F = 65°
Therefore
XI/Sin 65 = 9/Sin 52
Cross multiplying, it becomes
XISin52 = 9Sin65
0.788XI = 9 × 0.906
0.788XI = 8.154
XI = 8.154/0.788
XI = 10.35
Answer:
13916.6m^3
Step-by-step explanation:
Answer:
p(-2) = -11
p(0) = -3
p(5) = 17
Step-by-step explanation:
<u>Step(i):</u>-
Given that the polynomial function p(x) = -3 +4x ..(i)
Given x =-2 , 0 and 5
put x =-2 in equation (i)
p(-2) = -3 +4(-2)
= -3 -8
p(-2) = -11
<u><em>Step(ii):-</em></u>
put x =0 in equation (i)
p(0) = -3 +4(0)
= -3 +0
p(0) = -3
<u><em>Step(iii):-</em></u>
put x = 5 in equation (i)
p(5) = -3 +4(5)
= -3 +20
p(5) = 17
<u><em></em></u>
