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:

$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:

d. x + 6 is a factor of the polynomial

Step-by-step explanation:

Very simple rule to remember when dividing polynomials, if you divide and there is no remainder, the 2nd term (x + 6) is a factor of the polynomial.

Answer:

Step-by-step explanation:

Payment per hour is $8

commission is 15%

Total number of hours worked for 2 weeks is 73 hours

Total sales=$2095

commission earned for 2 weeks:

15/100×2095

=$314.25

Total amount earned in 73 hours:

73×8=$584

Total amount earned in commission and wages:

584+314.25

=$898.25

Answer:

D

Step-by-step explanation:

[tex]\huge\boxed{(0, 23)}[/tex]

Hey there! We'll solve this problem in three main steps. First, we'll find the slope of the line. Then, we'll find the equation line in point-slope form. Finally, we'll change the equation to slope-intercept form so we can tell what the y-intercept is.

We can use the slope formula, where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are two known points on the line.

[tex]\begin{aligned}m&=\frac{y_2-y_1}{x_2-x_1}&&\smash{\Big|}&&\text{Use the slope formula.}\\&=\frac{-10-1}{3-2}&&\smash{\Big|}&&\text{Substitute in the known values.}\\&=\frac{-11}{1}&&\smash{\Big|}&&\text{Subtract.}\\&=\boxed{-11}&&\smash{\Big|}&&\frac{x}{1}=x\end{aligned}[/tex]

Now that we have the slope, we can use it together with one of the points to get the line in point-slope form. Then, we can distribute and add to get the line in slope-intercept form.

[tex]\begin{aligned}y-y_1&=m(x-x_1)&&\smash{\Big|}&&\text{Use point-slope form.}\\y-1&=-11(x-2)&&\smash{\Big|}&&\text{Substitute in the slope and one point.}\\y-1&=-11x+22&&\smash{\Big|}&&\text{Distribute.}\\y&=-11x+\boxed{23}&&\smash{\Big|}&&\text{Add $1$ to both sides.}\end{aligned}[/tex]

We can now clearly see that the y-intercept of the line is [tex]23[/tex], or [tex](0, \boxed{23})[/tex] as a point.

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.

150 divided by 12

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

Answer:

71.25 mph

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°.

Answer:

5, 2, - 3

Step-by-step explanation:

To find the first 3 terms substitute n = 1, 2, 3 into the explicit rule, that is

f(1) = 6 - 1² = 6 - 1 = 5

f(2) = 6 - 2² = 6 - 4 = 2

f(3) = 6 - 3² = 6 - 9 = - 3

The first 3 terms are 5, 2, - 3
