Step-by-step explanation:

The function f is given in three equivalent forms.
Which form most quickly reveals the vertex?
Choose 1 answer:
f(x) = 3x^2+ 36x + 33
f(x) = 3(x+6^2-75
f(x)=3(x+1)(x+11)
What is the vertex?

Answers

Answer:

Step-by-step explanation:

Look what happens when you factor the 3 out of the first choice:

f(x) = 3x^2+ 36x + 33 = f(x) = 3(x^2+ 12x) + 11

We can "complete the square:"  x^2 + 12x becomes x^2 + 12x + 36 - 36, which, in turn, becomes (x + 6)^2 - 36

so that the original f(x) becomes   f(x) = 3(x + 6)^2 - 36 + 33, or

f(x) = 3(x + 6)^2 - 3

Comparing this to

f(x) =a(x - h)^2 + k reveals that h = -6 and k = -3.  Thus, the vertex is at (-6, -3).

Amanda is pumping water into an aquarium at a rate of 12 liters per minute the aquarium had 42 liters of water in it before she started her goal is given by 13x+42<_234 where x is the number of minutes she pumps water into the aquarium

Answers

Answer:

Let x represent minutes.

The inequality derived from the question is...

58 > 18 + 5x

Solve for x...

58 > 18 + 5x

58 - 18 > 5x

40 > 5x

40/5 > x

8 > x

So it will take more than 8 minutes to have 58 liters.

Look at the figure. How can you prove the triangles are congruent?




It is not possible to determine if the triangles are congruent.


∆ABD ≅ ∆CBD by the SAS Postulate.


∆ABD ≅ ∆CBD by the SSS Postulate.

Answers

Answer:

You can prove them to be congruent.

Step-by-step explanation:

You would use the SSS Postulate. This means Side Side Side.in the figure shown you can see sides AB and BC have one line crossing them making them equal. Same with side AD and CD. With side BD they are congruent because they are equal in size and share both triangles.

2.9 because if you look at place value, behind the decimal it goes, tenths hundredths thousandths, and so on

So in this case, 2.85 would be rounded to 2.9

Donald has two bags of grapes.
• Bag A contains g grapes.
• Bag B contains 40% fewer grapes than bag A.
The expression g – 0.40g can be used to find the number of grapes in bag B. Donald correctly simplifies the expression until it has just one term. What is the coefficient of g in Donald’s simplified expression?
Enter your answer in the box

Answers

G for bag A could also be written as 1g

The equation could then be written as 1g - 0.40g, which if you subtract can be solved as 0.60g

Step-by-step explanation:

Here, we want to divide the given polynomial

To get this, we can use the method of long division

P(x) will be the quotient of the division, while k will be the remainder of the division

We can see the long division used in as seen in the attachment

So, we have the result as;

In rhombus BCDE, m angle B=68. Find m angle E.
NEED HELP!!!

Answers

Answer:

m<E=22

Step-by-step explanation:

m<B and m<D are congruent therefore, m<D=68

m<C and m<E are congruent.

All interior angles if a rhombus adds up to 180 degrees.

So... 68+68=136

Subtract the 136 from 180

180-136=44

Because m<C and m<E are congruent divide 44 by two

44/2= 22

m<C and m<E equal 22
