Given sec A = - squareroot 85/6 and that angle A is in Quadrant II, find the exact value of
cot A in simplest radical form using a rational denominator.

Answer:

28x+8y-8

Step-by-step explanation:

Follow the orders of PEMDAS:  (parenthesis, exponents, multiplication, division, addition, subtraction)

If an equation you need to solve has parentheses, simplify the parentheses (most often using distribution) and then solve as you normally would. Simplify both sides of the equation as much as possible using the order of operations (distribute, combine like terms, etc.).

-6x -24y +34x +32y -8

Answer:

It is d. 3/2

Step-by-step explanation:

slope formula is rise over run or x2-x1/y2-y1. So it would be 6-0/4-0. That equals 6/4. You just need to simplify that by dividing both 6 and 4 by 2 and you get 3/2.

Answer:

29/200=0.14500

(1): "14.5" was replaced by "(145/10)".

Step 1:

simplify 29/2

Equation at the end of step:

29/2  ÷  100

Step 2:

Divide 29/2 by 100

Final result :

29/200=0.14500

Answer:

72%

Step-by-step explanation:

you can divide part of a whole by the whole to get a decimal

this decimal is the percentage when you move the decimal 2 places to the right

32 - 9 = 23 men

23/32 = .72 (rounded)

.72 = 72%

The number of chickens and goats will be 7 and 4, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

On farmer Palmer’s farm, the cats have got into the chicken coop and are causing chaos. Farmer Palmer counts in total, 11 heads and 30 legs.

We know that a goat has four legs and a chicken has 2 legs.

Let 'x' be the number of chickens and 'y' be the number of goats. Then the equations are given as,

x + y = 11                  ...1

2x + 4y = 30           ...2

From equations 1 and 2, then we have

2(11 - y) + 4y = 30

22 - 2y + 4y = 30

2y = 8

y = 4

Then the value of 'x' is given as,

x = 11 - 4

x = 7

The number of chickens and goats will be 7 and 4, respectively.

f(2)= -2, f(-2)= 2, odd

Step-by-step explanation:

1. f(2)=x^3-5x

2. f(2)= 2^3-5(2)

3. f(2)=8-10

4. f(2)= -2

5. f(-2)= x^3-5x

6. f(-2)= -2^3-5(-2)

7. f(-2)= -8+10

8. f(-2)= 2

We have x = 81 repeat itself. Any time x repeats, it means we don't have a function.

Put another way, the input x = 81 leads to more than one y output. A function is only possible if any given input leads to exactly one output. The input must be in the domain.

Answer:

Total deductions = $105.317

Step-by-step explanation:

Gross earning = $378

Deductions:

Federal withholding tax = $28

Social security tax = 6.2% of $378 = $23.436

Medicare tax = 1.45% of $378 = $5.481

Health insurance = $28

Total deductions is gotten by summing up all values above

28+23.436+5.481+20.4+28

= $105.317

The difference between gross earning and deductions

= 378-105.317

= $272.683

Answer:

see explanation

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

x² + y² = 49 ← is in this form with

r² = 49 ( take square root of both sides )

r = [tex]\sqrt{49}[/tex] = 7

Thus A = (7, 0 ) and B = (0, 7 )

To find M use the midpoint formula

M = ( [tex]\frac{7+0}{2}[/tex], [tex]\frac{0+7}{2}[/tex] ) = (3.5, 3.5 )

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = [tex]\frac{x_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (3.5, 3.5 )

m = [tex]\frac{3.5-0}{3.5-0}[/tex] = [tex]\frac{3.5}{3.5}[/tex] = 1

y = x ← equation of line passing through O and M

Answer:

Below in bold.

Step-by-step explanation:

(a)

At point A,  y = 0 so the coordinates of A are found as follows:

x^2+ 0^2 = 49

x^2 = 49

x = 7   so A is (7, 0).

In a similar way,  by putting x = 0 in the equation, we can show that

B = (0, 7).

(b)

M is the midpoint of the line AB so its coordinates are:

(7+ 0)/2, (0 + 7) /2 = (3.5, 3.5).

So the slope of OM  which also passes through the origin (0,0) is:

(3.5 - 0) /(3.5 - 0) = 1.

y - y1 = m (x - x1)

y - 3.5 = 1(x - 3.5)

y = x - 3.5 + 3.5

y = x is the required equation.

The equation that best models the relationship between the amount of compost used and the harvest yield is y = x+200

Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.

Given that, a graph that shows the harvest results of a farm, we need to construct an equation that will give a relation between the compost used and the yield,

So the coordinates are

(0,200)

(200,400)

(400,600)

(600,800)

Finding the slope,

600-400 / 400-200 = 200/200 = 1

The y-intercept is 200, so, the relationship is

y=200+x

Hence, the equation that best models the relationship between the amount of compost used and the harvest yield is y = x+200
