Answer:

Part 1) 0.65 more than -4.35 ----------> -3.70

Part 2) 0.65 more than -4.35 ---------> 5.11

Part 3) 4.34 added to -8 ---------------> -3.66

Part 4) 9.14 added to -9.14 -------------> 0

Step-by-step explanation:

Part 1) we have

0.65 more than -4.35

The algebraic expression is equal to the sum of the number -4.35 plus 0.65

-4.35+0.65=-3.70

Part 2) we have

1.98 added to 3.13

The algebraic expression is equal to the sum of the number 3.13 plus 1.98

3.13+1.98=5.11

Part 3) we have

4.34 added to -8

The algebraic expression is equal to the sum of the number -8 plus 4.34

-8+4.34=-3.66

Part 4) we have

9.14 added to -9.14

The algebraic expression is equal to the sum of the number -9.14 plus 9.14

-9.14+9.14=0

Find the angle θ between u = <7, –2> and v = <–1, 2>.
Dmitry_Shevchenko [17]

The angle between two vectors is:

CosФ = u - v / Magnitude(u) x magnitude(v)

Magnitude of u = SQRT(7^2 + -2^2) = SQRT(49 +4) = SQRT(53)

Magnitude of v = SQRT(-1^2 +2^2) = SQRT(1 +4) = SQRT(5)

u x v = (7 x -1) + (-2 x 2) = -7 + -4 = -11

cosФ = -11 / sqrt(53) x sqrt(5)

cosФ = -11sqrt265) / 265

Ф =cos^-1(-11sqrt265) / 265)

Ф=132.51 degrees.

A company sells widgets. The amount of profit, y, made by the
vfiekz [6]

Answer:

846.06 units

Step-by-step explanation:

The amount of profit, y, made by the  company, is related to the selling price of each widget, x, by the given  equation as follows :

y = -4x^2 + 183x- 1247 ...(1)

We need to find out the maximum amount of profit  the company can make.

For maximum profit put dy/dx = 0

So,

\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87

Put x = 22.87 in equation (1). So,

y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06

So, the maximum profit is 846.06 units.
