Term of rank n in a G.P: a₅ = arⁿ⁻¹
a₂ = a₁.r²⁻¹ = a₁.r = - 24
a₅ = a₁.r⁵⁻¹ = a₁.r₄ = 1536 ↔ a₁.r x r³ = 1536, but a₁.r = - 24
then: (-24) x r³ = 1536
r³ = (1536)/(-24) and r³ = - 64³ and r = ∛- 64 = r and r = -4
If r = -4 then a₁ =6 and the equation becomes :
a₅ =a₁r⁴ or a₅ =6(-4)⁴
The given equation is confusing since it written straight
without any symbols or parenthesis. I can write the equation in two forms:
(1 / 4) d + 7 --->
1
and
(1 / 4 d) + 7 --->
2
For equation 1, the variable d is first multiplied by 1 /
4 before adding up with the number 7. So in this case, the correct phrase would
be something like:
“The sum of one fourth a number and seven”
For equation 2, this is more complicated since the
variable is on the denominator side. The number 1 is divided by the product of
4 and variable d then summed up with the number 7. The correct phrase for this
one would be something like:
“The sum of the quotient of one over four times a number
and seven”
Select which equation is the correct one.
Triangle JKL was rotated 90° counterclockwise and then refrected across the line y = -4.
Answer: b₂=2A/h-b₁
Step-by-step explanation:
A =1/2 (b₁ + b₂)h
2A=(b₁ + b₂)h
2A/h=b₁ + b₂
b₂=2A/h-b₁
