Answer:

$\large \boxed{272175}$

Step-by-step explanation:

We can use the exponential growth formula:

y = a(1+r)ˣ

where

y = amount after x time

a = initial amount

r = growth rate as a decimal fraction

x = number of years

Data:

a = 170 000

r = 0.04

Calculations:

$\begin{array}{rcll}y &= &170 000(1.04)^{12} & & \\& = &170 000 \times 1.601032 &\\& = &\mathbf{272175} &\\\end{array}\\\text{The population will be $\large \boxed{\mathbf{272175}}$ in 12 yr}$

The figure below also shows that the population will grow to about 272 000 in 12 yr.

Using the information given, select the statement that can deduce the line segments to be parallel. If there are none, then sele

we know that

1) If the line segment AB is parallel to the line segment DC

then

m∠1=m∠D -------> by corresponding angles

2) If the line segment AD is parallel to the line segment BC

then

m∠3=m∠B -------> by corresponding angles

Answer:

Step-by-step explanation:

The picture is a bit blurry, but from what i can see, i'd say C (whichever one has -4 x 3 x 1 under the square root.)

So for this, you need to know the quadratic formula, which is:

$\frac{-b ± \sqrt{b^{2} -4ac} }{2a}$

*ignore the weird capital A, it keeps coming up when i try to use the ± symbol

They have given you the equation of a quadratic, so the first thing you have to do is rearrange it, so that $x^{2}$ comes first.

So now we have the equation: 3 $x^{2}$  - 2x +1

*the quadratic formula uses a, b and c, but they are specific. a is always the coefficient of $x^{2}$ , b is always the coefficient of x and c is always the constant (number without an x)

So, i can find that, in this case:

a = 3 b= -2 c=1

Now substitute each of those values it into the original quadratic equation:

$\frac{-(-2) ± \sqrt{(-2)^{2} -4(3)(1)} }{2(3)}$
