Step-by-step explanation:

Given:

MATH

100 3.0 A (4)

123 3.0 B (3)

137 3.0 B (3)

264 4.0 D (1)

Find:

Grade point average

Computation:

Grade point average = ∑[Subject credit × Grade point] / ∑[Subject credit]

Grade point average = [3(4)+3(3)+3(3)+4(1)]/ [3+3+3+4]

Grade point average = 34 / 13

Grade point average = 2.62 (approx)

If a polynomial function f(x) has roots 1+square root of 2 and-3, what must be a factor of f(x)?

nevsk [136]

To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to $x$ , and then we are going to factor backwards.

We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to $x$ and factor backwards:
$x=-3$
$x+3=0$
$(x+3)$ is a factor of our polynomial.

We also know that another root of our polynomial is $1+ \sqrt{2}$ , so lets set $1+ \sqrt{2}$ equal to $x$ and factor backwards:
$x=1+ \sqrt{2}$
$x-1= \sqrt{2}$
$x-1- \sqrt{2}=0$
$(x-(1+ \sqrt{2})=0$
( $(x-(1+ \sqrt{2} ))$ is a factor of our polynomial.

We can conclude that there is no correct answer in your given choices.

A piece of wire of length L will be cut into two pieces, one piece to form a square and the other piece to form an equilateral t

inn [45]

Answer:

(a) square: L; triangle: 0.

(b) square: L·(-16+12√3)/11; triangle: L·(27-12√3)/11

Step-by-step explanation:

<u>Strategy</u>: First we will write each area in terms of its perimeter. Then we will find the total area in terms of the amount devoted to the square. Differentiating will give a way to find the minimum total area.

In terms of its perimeter p, the area of a square is ...

A_square = p^2/16

In terms of its perimeter p, the area of an equilateral triangle is ...

A_triangle = p^2/(12√3)

Then the total area of the two figures whose total perimeter is L with "x" devoted to the square is ...

A_total = x^2/16 + (L-x)^2/(12√3)

(a) We know when polygons are regular, the one with the most area for the least perimeter is the one with the most sides. Hence, the total area is maximized when all of the wire is devoted to the square.

(b) The derivative of A_total with respect to x is ...

dA/dx = x/8 -(L-x)/(6√3)

This will be zero when ...

x/8 = (L-x)/(6√3)

x(6√3) = 8L -8x

x(8 +6√3) = 8L

x = L·8/(6√3 +8) = 8L(6√3 -8)/(64-108)

x = L·(12√3 -16)/11

The total area is minimized when L·(12√3 -16)/11 is devoted to the square, and the balance is devoted to the triangle.

How can find the estimate of the sum of the two fractions

vodka [1.7K]

Answer:

To make a high estimate for the sum of two fractions, find the commnon denominator and add them.

Step-by-step explanation:

To make a high estimate for the sum of two fractions in a word problem, rhe following steps are required.

Let the two fractions be represented as and

To perfrom the operation +

Step 1 : Check if the denominators of the fraction are same. If so then, then add the numerators directly by keeping the same denominator.

Step 2: If the denominators are different, then find the common denominator between the fractions and multiply them accordingly. Then perform the addition operation.
