Answer:

Step-by-step explanation:

x+20=11x+30  minus x from both sides

20=10x+30  minus 30 from both sides

-10=10x  divide by 10

x= -1

Answer:

Step-by-step explanation:

Use the point-slope formula.

y - y_1 = m(x - x_1)  when :     x_1 = -5  and    y_1 =3 and   m= -6/5

the equation :   y - 3 = -6/5(x +5)

Answer:

Step-by-step explanation:

Use the point-slope formula.

y - y_1 = m(x - x_1)  when :     x_1 = -5  and    y_1 =3 and   m= -6/5

the equation :   y - 3 = -6/5(x +5)

Answer:

if Maria sells 6 she will make 12 add base wage she earned 15. if eve sells 1 she will also make a profit of 15

Answer:

C) neither

Step-by-step explanation:

they add up to 190

complementary adds up to 90

supplementary adds up to 180

Answer:

supplementary

Step-by-step explanation:

sum = 180

Answer:

$3

Step-by-step explanation:

Given that:

p = 8 - ln(x) when 5 < x < 500

where;

x = The total number of dogs sold

Then;

The total revenue = x * p

R = x(8 - ln(x))

R = 8x - xln(x)

The Company thus pays 1 dollar per dog

i.e.

The total cost C = 1 * x = x

Then: Profit = R - C

P = 8x - xln(x) - x

P = 7x - xln(x)

Differentiating P in respect to x

dP/dx = 7 - d/dx(xln(x))

dP/dx = 7 - x*d/dx(ln(x)) - ln(x)*d/dx(x)

dP/dx = 7 - x(1/x) - ln(x)

dP/dx = 6 - ln(x)

Since this must be maximized, dP/dx is set to be equal to 0

6 - ln(x) = 0

ln(x) = 6

x = e^6

Now, p = 8 - ln(x)

Plug in the value of x :

p = 8 - ln(e^5)

p = 8 - 5

p = 3

Therefore, each dog must be priced at $3 to maximize the profit.

Answer:

let the 4 consecutive even number be x, x+2,x+4,x+6

now

x+x+2+x+4+x+6=324

or             4x+12=324

or                   4x=314

                        x=78

least integer=78

Answer:

40

Step-by-step explanation:

8+1=9

16+2=18

24+3=27

32+4=36

40+ 5=45

Answer:

B

Step-by-step explanation:

sinA=opp/hyp

sinA=16/20=4/5

cosA=adj/hyp

cosA=12/20=3/5

Answer:

We found sinA= 3/5 and cosA=4/5

Option A is correct.

Step-by-step explanation:

The formula to find sin A is :

[tex]sin A = \frac{Perpendicular}{Hypotenuse}[/tex]

while the formula to find cos A is:

[tex]cosA=\frac{Base}{Hypotenuse}[/tex]

So, in the figure given:

Base = 16

Perpendicular = 12

Hypotenuse = 20

Now, finding sin A and cos A using formulas and above values

[tex]sin A = \frac{Perpendicular}{Hypotenuse}\\sin A = \frac{12}{20}\\sinA=\frac{3}{5}[/tex]

[tex]cosA=\frac{Base}{Hypotenuse}\\cosA=\frac{16}{20}\\cosA=\frac{4}{5}[/tex]

So, we found sinA= 3/5 and cosA=4/5

Option A is correct.

Answer:

y=1/2x+2

Step-by-step explanation:

Answer:

Example: Find the radian measure of the angles −70° and 120°.

Solution: To find the radian measure of −70° we multiply −70 by the conversion factor /180. We get

Similarly, for 120° we obtain

Note that when we write an angle as a fractional amount of , for example 2/3 times  we write the result either as the numerator times  divided by the denominator or as the fraction times . So the two values

are equivalent ways of writing the same number. You will see both methods used in the text and in the exercises.

Example: Find the degree measure of /12.

Solution: The conversion factor for going from radians to degrees is 180/. We get

and so the radian measure of /12 is 15°.
