1 answer:
babymother [125]3 years ago
8 0

Answer:

A. (2i)(8) = d. 16i

B. 16i³ = b. -16i

C. (2i)⁴ = a. 16

D. (2i)(8i) = c. -16

Step-by-step explanation:

A. Multiply 2i by 8 to get 16i, which corresponds to d.

B. The exponent is 3 more than a mulitple of 4 in 16i³, so the answer is negative. -16i corresponds to b.

C. (2i)⁴ has an exponent that is a multiple of 4, so the i isn't needed. 16 corresponds to a.

D. (2i)(8i) simplifies to 2(8) * i². The exponent is 2 more than a multiple of 4, so the answer is negative, without an i. -16 corresponds to c.

Number 8 is confusing
suter [353]

A landscaper is creating a rectangular flower bed such that the width is half of the length . the area of the flower bed is 34 square feet . write and solve the equation determine the width of the flower bed , to nearest tenth of floor .

Answer :

it says that width is half the length . which also implies that length is double the width . as we shift the 2 from denominator , it gets multiply on RHS

let the length be 2x

and

width be = x

length × breadth = 34

2x × x = 34

2x^2 = 34

{x}  =  \sqrt{34}

x = width = 5.8309518948
