Answer:

um hope this helps :D

Step-by-step explanation:

A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system. The problem can be expressed in narrative form or the problem can be expressed in algebraic form.

family has a square driveway with an area of 210.25 m exponent 2. Find the perimeter of the driveway. Round your answer to the n

miv72 [106K]

Answer:

191 ft.

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) of square = 210.25 m²

Perimeter (P) =?

Next, we shall determine the length of each side of the drive way. This can be obtained as follow:

Area (A) of square = 210.25 m²

Length (L) =?

Area of a square is given by:

A = L²

210.25 = L²

Take the square root of both side

L = √210.25

L = 14.5 m

Thus, the length of each side of the drive way 14.5 m

Next, we shall determine the perimeter of the drive way. This can be obtained as follow:

Length (L) = 14.5 m

Perimeter (P) of square =?

Perimeter of a square is given by:

P = 4L

P = 4 × 14.5

P = 58 m

Finally, we shall convert 58 m to foot. This can be obtained as follow:

1 m = 3.3 ft

Therefore,

58 m = 58 m × 3.3 ft / 1 m

58 m = 191.4 ft

58 m = 191 ft

Thus, 58 m is equivalent to 191 ft.

Therefore, the perimeter of the drive way is 191 ft.

Simplify the expression. 16(1/2x)^4 The simplified expression is

SVEN [57.7K]

Answer:

1/x^4

Steps:

(1/2x)^4 = 1/2^4x^4

= 16 * 1/2^4x^4

Multiply fractions: a * b/c = a * b/c

= 1 * 16/2^4x^4

Multiply the numbers: 1 * 16 = 16

16/2^4x^4

Factor 16: 2^4

= 2^4/2^4x^4

Cancel the common factor: 2^4

= 1/x^4

Give an example of each of the following or explain why no such example exists. (a) Two polynomials of degree 1 in Z4x whose pro

andre [41]

Answer:

Step-by-step explanation:

(a)

let, f(x) = 2x+1 & g(x) = 2x+2

So, f(x).g(x) = (2x+1).(2x+2) = 4x² + 6x + 2 = 2x+2 in $Z_4[x]$

So, product of two 1 degree polynomials is a 1-degree polynomial in $Z_4[x]$

(b)

let, f(x) = 2x³ - 3x² + 5x + 7 & g(x) = -2x³ + 3x² + x + 3 be two polynomials in R[x]

So, f(x) + g(x) = 6x + 10, which is a polynomial of degree 1 in R[x]

(c)

this is not possible, since, if f & g are 2 polynomials in any polynomial ring S, then, we always have,

deg(f.g) <= deg(f) + deg(g)

So, deg(f.g) = 5 (as desired) but, deg(f) + deg(g) = 2+2 = 4 but, 4 < 5

So, this is not possible.

So, no such example exists.
