A small town experienced an explosive population increase Originally the town had population 170 within 3 years the town's popul

ation increased by 400% what is the town current population
Mathematics
1 answer:
Lunna [17]2 years ago
3 0

Answer:

Step-by-step explanation:

We need to first find out how much 400% of 170 is and then add that increase to the original 170 people.

4(170) = 680 and

680 + 170 = 850 people after 3 years.

Please help with at least one of these ( I accept 1 answer if you have it; make sure you are 100% positive its correct though!)
Trava [24]

So I know some of them but not all them sorry

5. If m<5=70 then m<6= <em><u>20</u></em>

<em>Why? </em> Because there is a 90 degree angle there and if m<5 is 70 all you have to do to get m<6 is subtract 70 from 90 and you get 20 degrees

6. If m<5=70 then m<1= <em><u>90 </u></em> and m<4=<em><u>90 </u></em>

<em>Why? </em>Because you can see based on the drawing that they form right angles

4a. FGK is right angles

4b. The measure of FGK is 90 in total

<em>Why? </em> It has the right angle

Hope this helps:) this was all I could remember

At which value in the domain does f(x) = 0?
bekas [8.4K]

Answer:

C

Step-by-step explanation:

f(x)=0 at points of intersection of the graph of the function with x-axis.

From the diagram you can see that the graph of the function intersects x-axis at three points:

somewhere between -3 and -2;

somewhere between -1 and 0;

at x=1.

Since x=1 is the value of x from the domain, then correct choice is option C.

During second period, Evan completed a grammar worksheet. He got 27 out of 36 questions correct. What percentage did Evan get co
s2008m [1.1K]

Answer:

75%

Step-by-step explanation:

So we have to multiply by 100: \frac{27}{36} × 100

Divide 27 and 36 by 9: \frac{3}{4} × 100

Divide 100 by 4: 3 × 25

Evan got 75% correct

The minimum/maximum value of the function y = a(x − 2)(x − 1) occurs at x = d, what is the value of d?
daser333 [38]

Answer:

d=\frac{3}{2}=1.5

Step-by-step explanation:

We have the function:

y=a(x-2)(x-1)

And we want to find x=d for which the minimum/maximum value will occur.

Notice that our function is a quadratic in factored form.

Remember that the minimum/maximum value always occurs at the vertex point.

And remember that the x-coordinate of the vertex is the axis of symmetry.

Since a quadratic is always symmetrical on both sides of its axis of symmetry, a quadratic’s axis of symmetry is the average of the two roots/zeros of the quadratic.

Therefore, the value x=d such that it produces the minimum/maximum value is the average of the two roots.

Our factors are <em>(x-2) </em>and <em>(x-1)</em>.

Therefore, our roots/zeros are <em>x=1, 2</em>.

So, the average of them are:

d=\frac{1+2}{2}=3/2=1.5

Therefore, regardless of the value of <em>a</em>, the minimum/maximum value will occur at <em>x=d=1.5</em>.

Alternative Method:

Of course, we can also expand to confirm our answer. So:

y=a(x^2-2x-x+2)\\y=a(x^2-3x+2)\\y=ax^2-3ax+2a

The x-coordinate of the vertex is still going to be the place where the minimum/maximum is going to occur.

And the formula for the vertex is:

x=-\frac{b}{2a}

So, we will substitute <em>-3a</em> for <em>b</em> and <em>a</em> for <em>a</em>. This yields:

x=-\frac{-3a}{2a}=\frac{3}{2}=1.5

Confirming our answer.

The two cheese questions please!!
Reil [10]

Answer:

Ham costs: $8.249 repeating

Overall cost: 1.26 repeating

Step-by-step explanation:

$4.95 x 5/3= 8.249

2/3 + 3/5= (2 x 5) + (3 x 3)/ 3 x 5=

19/ 15 or 1 4/15

15 divided by 19= 1.26 repeating
