Answer:

When written in "vertex form":

• (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.

• the h represents a horizontal shift (how far left, or right, the graph has shifted from x = 0).

• the k represents a vertical shift (how far up, or down, the graph has shifted from y = 0).

• notice that the h value is subtracted in this form, and that the k value is added.

If the equation is y = 2(x - 1)2 + 5, the value of h is 1, and k is 5.

If the equation is y = 3(x + 4)2 - 6, the value of h is -4, and k is -6.

Suppose that a large mixing tank initially holds 900 gallons of water in which 50 pounds of salt have been dissolved. Another br

borishaifa [10]

Answer:

dA/dt= 12-2A(t)/900+t

Step by step Explanation:

Given:

rate of 3 gal/min

concentration of the solution entering is 4 lb/gal,

The equation of the solution can be expressed as

dA/dt = R(1)- R(2)

Where R(1)=( concentration of the salt at inflow* rate of input of given brine)

R(2)= ( concentration of the salt at inflow* rate of output of given brine)

R(1)= 3 gal/min× 4 lb/gal=12Ib/min

But the solution is been pumped slowly, the rate of the accumulation can calculated as;

(3 gal/min- 2 gal/min)=1gal/min

But after t min we will be having 900+t gallons present in the tank

A jumbo size 90 ounces drink at a certain gas station has 890-calories. How many calories are there in a 14 ounce drink

Degger [83]

The number of calories in 14-ounces drink is 138.44

Step-by-step explanation:

Given

Amount of jumbo size drink = 90 ounces

Calories in jumbo size drink = 890-calories

Quantity of smaller drink = 14 ounces

We will use the proportions to solve the questions

$ounces: calories::ounces:calories$

Let x be the number of calories in the smaller drink

$90: 890::14:x\\\frac{90}{890} = \frac{14}{x}\\x = \frac{890*14}{90}\\x = \frac{12460}{90}\\x = 138.44$

The number of calories in 14-ounces drink is 138.44
