The Y intercept is approx 4. The Y intercept represents the number of matches won. I do not know Part B: (

A.
y-intercept is where the line crosses the y axis
it seems to cross at y=4

B. seems to be linear, so
y=mx+b is equation
m=slope
b=y intercept
we know that yintercept=4=b

slope=rise/run=z/t
it for every z units it goes up, it goes to the right t units
seems to go up 17 for every 11 units it goes to the right
so slope=17/11

equation is $y=\frac{17}{11}x+4$
so predict that after 13 months (x=13), we have y=(17/11)13+4=221/11+4≈24 games won

The equation of a parabola is 1/32 (y−2)2=x−1 .

Andru [333]

The given equation of parabola is

$\frac{1}{32} (y-2)^2 = x-1$

Which can also be written as

$x = \frac{1}{32} (y-2)^2 +1$

Here vertex (h,k) is (1,2)

And value of a is

$a = \frac{1}{32}$

Formula of focus is

$(h+ \frac{1}{4a} , k)$

Substituting the values of h,k and a, we will get

$(1+ \frac{1}{4*(1/32) } , 2} = (1+ 8,2) = (9,2)$

Therefore the correct option is the last option .

Order the following from least to greatest -- 0.209, 0.039, 0.21, 0.045

Zinaida [17]

Given numbers : 0.209, 0.039, 0.21, 0.045 .

In order to check the smallest number, we need to check tenth value of each number first.

0.209 has 2 in tenth place, 0.039 has 0 in tenth place, 0.21 has 2 in tenth place and 0.045 has 0 in tenth place.

In first step, we got two smaller numbers 0.039 and 0.045 because they both have 0 in tenth place and other two numbers 0.209 and 0.21 has 2's in tenth place.

Now, we will check hundredth place number in 0.039 and 0.045.

0.039 has 3 in it's hundredth place and 0.045 has 4 in it's hundredth place.

Therefore, 0.039 would be smallest number and 0.045 would be second smaller number.

Now, we woiuld check hundredth place number in 0.209 and in 0.21.

0.209 has 0 in it's hundredth place and 0.21 has 1 in it's hundredth place.

Therefore, 0.209 is smaller than 0.21 and third smaller number.

So, finally 0.21 would be greatest number.

So, the order from least to greatest is 0.039, 0.045, 0.209, 0.21 .

So, the order will be c < a < d < b.

Find the missing length <br> . Leave your answers in simplest radical form

KIM [24]

Use the Pythagorean theorem:

$x^2+7^2=14^2\\\\x^2+49=196\qquad\text{subtract 49 from both sides}\\\\x^2=147\to x=\sqrt{147}\\\\x=\sqrt{49\cdot3}\\\\x=\sqrt{49}\cdot\sqrt3\\\\\boxed{x=7\sqrt3\ mi}$
