Determining Exponential Growth and Decay in Exercise, use the given information to write an exponential equation for y. Does the

frozen [14]

Answer:

$y = Ke^{5.2t}$

Exponential growth

Step-by-step explanation:

We can solve this differential equation by the separation of variables method.

We have that:

$\frac{dy}{dt} = 5.2y$

So

$\frac{dy}{y} = 5.2dt$

Integrating both sides

$\ln{y} = 5.2t + K$

In which K is the value of y when t = 0.

We apply the exponential to both sides, so:

$y = Ke^{5.2t}$

This is our exponential equation. Since the power of e is a positive value, the function represents exponential growth.

Half a pepperoni pizza plus three fourths of a ham and pineapple pizza contains 765 calories 1/4 of a pepperoni pizza plus a who

yulyashka [42]

Answer:

Correct choice is D (In a whole pepperoni pizza are 660 calories, in in a whole ham and pineapple pizza are 580 calories).

Step-by-step explanation:

Let x calories be the number of calories a whole pepperoni pizza contains and y calories be the number of calories a whole ham and pineapple pizza contains.

1. If half a pepperoni pizza plus three fourths of a ham and pineapple pizza contains 765 calories, then

$\dfrac{1}{2}x+\dfrac{3}{4}y=765.$

2. If 1/4 of a pepperoni pizza plus a whole ham and pineapple pizza contains 745 calories. then

$\dfrac{1}{4}x+y=745.$

3. Multiply each equation by 4 and get a system of two equations:

$\left\{\begin{array}{l}2x+3y=3060\\x+4y=2980\end{array}\right.$

From the second equation $x=2980-4y$ , then

$2(2980-4y)+3y=3060,\\ \\5960-8y+3y=3060,\\ \\-8y+3y=3060-5960,\\ \\-5y=-2900,\\ \\y=580.$

Then

$x=2980-4\cdot 580=2980-2320=660.$

A triangle has squares on its three sides as shown below. What is the value of x? Three squares having side lengths 3 cm, x cm,

Pani-rosa [81]

Answer:

The value of x is 5 centimeters.

Therefore, option 3 is correct.

Step-by-step explanation:

A triangle has three sides 3,x and 4 cms

Since the triangle is right angle triangle so, it will follow the Pythagoras theorem:

$hypotenuse^2=side^2+side^2$ (1)

We have been given three sides x,3 and 4

On substituting the values in (1) we get:

$x^2=3^2+4^2$

$x^2=9+25$

$\Rightarrow x=5$

Hence, the value of x is 5 centimeters.

Therefore, option 3 is correct.

Please look at the attachment for the figure.
