Y=-x^2-10x+24 What is the y value of the vertex?
emmasim [6.3K]

Answer:

Step-by-step explanation:

1.) Get the equation in the form y = ax^2 + bx + c.

2.) Calculate -b / 2a. This is the x-coordinate of the vertex.

3.) To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

1.) y = -x^2 - 10x + 24

2.) -(-10) / 2(-1) = -5

3.) y = -(-5)^2 - 10(-5) + 24

    y = -25 + 50 + 24

    y = 49

HELP ME ASAP

a.
60 ounces = 3 pounds

So no, you don’t have as much fruit as you need.

b.
60 ounces —> 3 pounds
X ounces —> 4 pounds

Cross product :

(60 x 4) / 3 —> 240/3 = 80

So in order to have 4 pounds of fruits, you need 80 ounces of fruits.

You already have 60 ounces of fruits.

X + 60 = 80

80 - 60 = X

20 = X

You need 20 more ounces to have 4 pounds of fruits.

The function P(t)=87,000e^0.106t models the population of a city, t years after 2010. How many people lived in the city in 2010?
Bumek [7]

Answer:

87,000 ; 10.6%

Step-by-step explanation:

Given the function :

P(t)=87,000e^0.106t

P(t) is an exponential function ; comparing the given function to the general form of an exponential function :

y = Ae^rt

Where,

A = initial amount ; r = growth rate ; t = time

The Given function models t years after 2010, that is the 2010 population is the initial population of the city.

Comparing the general exponential equation with the function given:

A = 87,000 = population of city in 2010

The growth rate :

rt from the general equation compares to 0.106t in the given function.

rt = 0.106t

r = 0.106

Hence, the rate of change = 0.106 * 100% = 10.6%
