What is the y intercept of the line -9 + 3y= 18

Answers

Answer 1
Answer:

Answer:

0,9

Step-by-step explanation:

Answer 2
Answer:

Answer:

y=9

Step-by-step explanation:

In this equation you would add 9 to get the y on a side by itself that would get you 3y=27, then you would divide both sides by 3 and end up with your y-intercept to be 9.

If the population of a country increases at a rate of 1.5% annually, and its current population is 430,000, how many years will it take for the population to triple?

Answers

Answer:

Hence, it will take about 73 years  for the population to triple.

Step-by-step explanation:

For this case we have an exponential function P(t) which represents the population at time 't' ; which is given as:

i.e. the equation is represented of the form:

 P(t)=Ab^t

 Where,

 A: initial amount ( Here we have A=430000)

 b: growth rate  (Here we have b=1.015)

 t: time in years.

As the population has to triple over the time.

 Hence, Substituting values we have:

 3* 430000=430000* (1.015)^t

⇒  3=(1.015)^t

Taking logarithmic function on both side we have:

\log3=t\log1.015

( Since \log m^n=n \log m )

⇒  t=(\log 3)/(\log 1.015)\n\nt=73.78876233

Hence, It will take for the population to triple about:

 t = 73 years

3p=p(1+0.015)^n
3=(1.015)^n
n=Log(3)/log(1.015)
n=??

The graphs of f(x) and g(x) are shown below:If f(x) = (x + 7)^2, which of the following is g(x) based on the translation?

g(x) = (x + 9)^2
g(x) = (x + 5)^2
g(x) = (x − 9)^2
g(x) = (x − 5)^2

Answers

The function that is based on the translation is g(x) = (x + 5)^2

How to determine the translation?

The function f(x) is given as:

f(x) = (x + 7)^2

The function f(x) is translated 2 units right to get function g(x)

This means that:

g(x) = f(x - 2)

So, we have:

f(x - 2) = (x -2 + 7)^2

Evaluate

f(x - 2) = (x + 5)^2

This gives

g(x) = (x + 5)^2

Hence, the function that is based on the translation is g(x) = (x + 5)^2

Look at the parallelogram ABCD shown below: The table below shows the steps to prove that if the quadrilateral ABCD is a parallelogram, then its opposite sides are congruent: Statement Reasons 1 AB is parallel to DC and AD is parallel to BC Definition of parallelogram 2
angle 1 = angle 2, angle 3 = angle 4 If two parallel lines are cut by a transversal then the _______________ are congruent 3
BD = BD Reflexive Property 4
triangles ADB and CBD are congruent If two angles and the included side of a triangle are congruent to the corresponding angles and side of another triangle then the triangles are congruent by ASA postulate 5
AB = DC, AD = BC Corresponding parts of congruent triangles are congruent
Which choice completes the missing information for reason 2 in the chart?
alternate interior angles
corresponding angles
same-side interior angles
vertical angles

Answers

Answer:

The correct option is 1.

Step-by-step explanation:

Statement                                          Reasons

1.   AB is parallel to DC and         Definition of parallelogram

    AD is parallel to BC

2.   angle 1 = angle 2,                   If two parallel lines are cut by a

    angle 3 = angle 4                    transversal then the alternate

                                                      interior angles are congruent

3.    BD = BD                                   Reflexive Property

4.    \triangle ADB\cong \triangle CBD                 ASA postulate

5.   AB = DC, AD = BC                  (CPCTC)

If two angles and the included side of a triangle are congruent to the corresponding angles and side of another triangle then the triangles are congruent by ASA postulate.

According to alternate interior angles theorem, two parallel lines are cut by a transversal then the alternate interior angles are congruent.

Therefore option 1 is correct.

alternate interior angles, i took the test and got it right
