The answer for each individual question is the same as you already but adding both of the problems together your answer would be -7x and 7y = -28

Or if you're looking for the values of X and Y then

X=14

Y=14

Find the interior angle on a regular polygon with 40 sides... please explain

Aloiza [94]

Given that the regular polygon with 40 sides.

We need to determine the interior angle of the polygon.

Sum of the interior angle:

Sum of the interior angle can be determined using the formula,

$(n-2)\times 180^{\circ}$

where n is the number of side.

Substituting $n=40$ in the above formula, we get;

$(40-2)\times180^{\circ}$

Simplifying the values, we get;

$38\times180^{\circ}=6840^{\circ}$

Thus, the sum of the interior angles is 6840°

Measure of each interior angle:

The measure of each interior angle can be determined using the formula,

$\frac{(n-2)\times 180^{\circ}}{n}$

where n is the number of side.

Substituting $n=40$ in the above formula, we get;

$\frac{(40-2)\times 180^{\circ}}{40}$

Simplifying the values, we get;

$\frac{38\times 180^{\circ}}{40}=\frac{6480}{40}$

Dividing, we get,

$n=171^{\circ}$

Thus, the measure of each interior angle is 171°

(1.1/1.2: Interpolating polynomials) Say we want to find a polynomialf(x) ofdegree 3,f(x) =a0+a1x+a2x2+a3x3,satisfying some inte

Hunter-Best [27]

(a) If

f(x) = a₀ + a₁ x + a₂ x ² + a₃ x ³

then from the given conditions we get the system of equations,

f (-1) = a₀ - a₁ + a₂ - a₃ = -1

f (1) = a₀ + a₁ + a₂ + a₃ = 2

f (2) = a₀ + 2a₁ + 4a₂ + 8a₃ = 1

f (3) = a₀ + 3a₁ + 9a₂ + 27x ³ = 5

(b) Similarly, if

f(x) = a₀ + a₁ x + a₂ x ² + a₃ x ³

then

f'(x) = a₁ + 2a₂ x + 3a₃ x ²

so that the given conditions yield the system,

f (1) = a₀ + a₁ + a₂ + a₃ = 0

f' (1) = a₁ + 2a₂ + 3a₃ = 2

f (2) = a₀ + 2a₁ + 4a₂ + 27a₃ = 3

f' (2) = a₁ + 4a₂ + 12a₃ = -1

What what are the rules for addition and subtraction with numbers in scientific notation?

andriy [413]

Addition and Subtraction in Scientific Notation. A number written in scientific notation is written as the product of a number between 1 and 10 and a number that is a power of 10. That is, it is written as a quantity whose coefficient is between 1 and 10 and whose base is 10.
