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).

The price of a watch was increased by 20% to £162.
What was the price before the increase?

Answers

Answer:

The answer is 135

Step-by-step explanation:

We can use formula: 162...120% since the price was increased by 20% which means it is 120%

So: 162...120%

x.... 100%

120x = 16200 => x = 135

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.

4x^2 -3 + 1/x

Where ;

p(x) =( 4x^2 -3) and k = 1

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;

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.

The map image shows the continents of Africa, Europe, and Asia. The map shows areas of plague outbreaks. There were outbreaks in China in 1333, along the Mediterranean Coast in 1347 and 1348, in Western Europe in 1348 and 1349, and Muscovy in 1351. The map shows that the disease was carried along trade routes connecting Asian and European countries. Considering the information in this map, why might the Black Death have affected the areas of Britain, Italy, and Palestine earlier than other areas in Europe? (1 point) Question 4 options: 1) These locations were geographically closer to Africa, where the Black Death was incubating. 2) These locations were places with large ports where infected sailors were mixing with others. 3) These locations had direct contact with explorers returning from the Americas. 4) The climate in these warm locations made the disease more likely to spread quickly. Recall your experimental setup from Lab 05A: a constant force was applied to a disc by attaching a mass to a light string wrapped around a mass-less pulley and hanging the mass over the edge of the apparatus. In the lab, you used energy conservation arguments to derive an expression for the angular velocity of the disc after the mass had fallen a distance x . Your goal now is to use kinematics and dynamics to confirm your expression. Use the following symbols throughout this question: m is the mass of the hanging mass, M is the mass of the disc, r is the radius of the pulley, R is the radius of the disc, x is the distance the mass has fallen, and g is the acceleration due to gravity. What is the linear acceleration of the mass after it has fallen a distance x The scatter plot and a line of best fit show the relationship between the length and width of 10 small animals a biologist finds in a park.
