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).

Answers

Answer:

A

Step-by-step explanation:

a positive number times a negative number is equal to a negative number.

Because all negative numbers have a value less than 0 the inequality sign must face towards the 0

The inequality sign also must be a < or > not a ≤ or ≥ as no positive number times -11 will equal 0

so the answer would be x < 0

Bob's Gift Shop sold 800 cards for Mother's Day. One salesman, Owen, sold 2% of the cards sold for Mother's Day. How many cards did Owen sell?

Answers

Owen sold 16 cards for Valentine’s Day.

The number of cards sold for Mother's Day by Owen is 16.

Total cards=800

Percentage of sold cards =2%

What is a percentage?

A percentage is a value per hundred.

So, 2% of 800 = (2*800)/100

2% of 800 =1600/100

2% of 800 =16

So, owen sold 16 cards

Hence, the number of cards sold by Owen is 16.

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

solve for x given the area of the rhombus is 340 cm squared

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.

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.
