I have to transfer this graph into a vertex form equation, but I'm not sure how to.

tino4ka555 [31]

Answer: y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2

Step-by-step explanation:

vertex form is y=a(x-h)^2 + k

here we can see the vertex is (3,0) which is (x,y). Or (h,k) in this case.

so to plug that into vertex form, we now have y=a(x-3)^2 + 0. or just y=a(x-3)^2.

now we need to find "a" which is the leading coefficient. to do that we can plug in the (6,-6) for the x and y parts of the above equation. so we'd have

-6=a(6-3)^2. which goes to -6=a(2)^2 which is -6=4a. divide each side by 4 to get a = -2/3. plug this in for a

the final equation would be y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2

Ursula and Velda live 4 km apart. They leave their homes at the same time, walking towards each other. If Ursula walks at a rate

vladimir2022 [97]

Answer: 250 m

Step-by-step explanation:

Given

Distance between Ursula and Velda house is 4 km or 4000 m

Ursula walks at the rate of $400\ m/h\ or\ \frac{20}{3}\ m/min$

Velda walks at the rate of $600\ m/h\ or\ 10\ m/min$

Time taken by them to cover 4000 m is

$\Rightarrow \dfrac{4000}{400+600}=4\ h\ or\ 240\ min$

Distance covered by them 15 min before they meet

Ursula $=\frac{20}{3}\times 225=1500\ m$

Velda $=10\times 225=2250\ m$

The total length covered by them is $=1500+2250=3750\ m$

They are $4000-3750=250\ m$ apart before they meet

Hello please help!!!!!!!

raketka [301]

Answer:

The length of VI = 4 cm

Solution:

The plot is like a quadrilateral and the fences are built on the diagonal

We know that for quadrilateral both the diagonals are in same height,

So as per the picture, GH = FI

Now we know that GV = 6.55, FV = 5.84, VH = 3.27

Hence,

GH = FI

$\Rightarrow GV + VH = VI + VF$

$\Rightarrow 6.55 + 3.27 = VI + 5.84$

$\Rightarrow VI = 6.55 + 3.27 - 5.84$

$\Rightarrow VI = 3.98$

Rounding off:

If the number that we are rounding is followed by 5 to 9, then the number has to be increased to the next successive number.

If the number that we are rounding is followed by 1 to 4, then the number has to remain the same.

Here the number to be round off is 3.98, 9 belongs to the first category stated above. So, 3 is increased to 4.

Hence, the length of VI = 4 cm.

Maria is play a game where you score -5 points each time you guess the correct answer.The goal is to get the lowest score.To win

oee [108]

Answer:

7

Step-by-step explanation:

Just notice that correct answers are whole numbers.

And, to win the game,Maria must have a score less than -80, it means she needs to score al least -85 ( it can not be -81, -82.. because 1 correct answer score -5, only multiples of -5 are accepted)

So, we take: $\frac{-85}{-5}$ = 7 correct answers to win the game.

Hope it will find you well.
