If m ∠ACD = 100°, then m ∠ACE = 80°, as ∠ACD and ∠ACE are supplementary angles.

Supplementary angles are the angles whose sum is equal to 180°. The angles formed when one straight line intersects the other, on the point of intersection on the same side of any line are always supplementary.

In the given question, AB and DE are two straight lines intersecting at point C. ∠ACD and ∠ACE lie on the same side of the line DE, thus they are supplementary angles.

Therefore, m ∠ACD + m ∠ACE = 180°.

But we know that m ∠ACD = 100°. So,

m ∠ACD + m ∠ACE = 180°,

or, 100° + m ∠ACE = 180°,

or, m ∠ACE = 180° - 100° = 80°.

Therefore, if m ∠ACD = 100°, then m ∠ACE = 80°, as ∠ACD and ∠ACE are supplementary angles.

Using translation concepts, the equation of the graph of f(x) is given as follows:

[tex]f(x) = \sqrt{x - 1}[/tex]

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

Function f(x) is a shift right of one unit of the square root function, hence x -> x - 1 and the equation is given by:

Answer:

Step-by-step explanation:

12x −3y=36  ⇔ 3y = 12x - 36

                          y = 4x - 12

y = 0 ⇔ 4x - 12 = 0 ⇔ 4x = 12 ⇔ x = 12/4 = 3

So (0 ; - 12) and (3 ; 0)

Answer:

x-intercept=3,  y-intercept=-12

Step-by-step explanation:

at x-intercept y=0 such that:

12x-3(0)=36

12x=36

If poaching reduces the population of an endangered animal by 6% and the criteria of population extinction is 20 with present population 1500 then it will take 3.62 years to reach to the mark of extinction.

Given Poaching reduces the population of endangered animals by 6% per year. The criteria of population extinction is 20. Present population being 1500.

Number of years taken by the population of endangered animals to reach to 20 mark can be calculated as under:

20=1500*[tex](1-0.06)^{n}[/tex]

20=1500*[tex]0.94^{n}[/tex]

20/1500=[tex]0.94^{n}[/tex]

0.133=[tex]0.94^{n}[/tex]

take log both sides

log(0.133)=log[tex]0.94^{n}[/tex]-------1

log(0.133)=nlog (0.94)

put the values log values:

log(0.133)=-0.8761

log(0.94)=-0.0268

Taking 1

-0.8761=n*(-0.0268)

n=0.8761/0.0268

n=3.269

The cost price of the good is $125.

Cost price is the total amount of money that it costs a manufacturer to produce a given product or provide a given service.

Given that a good has been sold for $150 which made a profit of 20% we need to find the cost price of the good,

Let the cost price be x,

So,

x × 120% = 150

x = 150 × 100 / 120

x = 125

Hence the cost price of the good is $125.

The complete equation is x^2 - 4x + (-2) = (-2)^2

The equation is given as:

x^2 - 4x + __ = (__)^2

_____________________________

Take the coefficient of x

k = -4

Divide by 2

k/2 = -4/2

k/2 = -2

Square both sides

(k/2)^2 = (-2)^2

_____________________________

Add the result of the above computation to both sides of x^2 - 4x + __ = (__)^2

Using a linear function, it is found that the product rs is rs = 81.

A linear function is modeled by:

y = mx + b

In which:

In this problem, when x changes by 68(from -64 to 68), y changes by -16(from 12 to -4), hence the slope is given by:

m = -16/64 = -0.25.

Hence:

y = -0.25x + b.

When x = 34, y = -4, hence this is used to find b.

-4 = -0.25(34) + b

b = 4.5.

Hence the function is:

y = -0.25x + 4.5.

f(r) = 0, hence:

-0.25x + 4.5 = 0

x = 4.5/0.25

x = 18

r = 18.

f (0) = s, hence s = 4.5.

Then the value of the product is:
