Answer: 1.5

Step-by-step explanation:

put it in a fraction so its 45/30 then divide both sides by 15 since they are divisable by 15.

45/30 divided by 15/15 is 3/2 which is equal to 1.5

Determine the inequality that can be used to model when the population of bacteria will be greater than or equal to 656,100. The

jenyasd209 [6]

The inequality is 100* $3^{t}$ ≤ 656100.

The correct option is (B).

<h3>What is inequality?</h3>

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

From the table attached below:

a=300, r= 900/300 = 3

As, it is GP

Now,

f(t) = $ar^{t-1}$

f(t) = $300*3^{t-1}$

f(t) = 300/3 * $3^{t}$

f(t) = 100* $3^{t}$

Inequality is used to determine greater than or equal to 656100

100* $3^{t}$ ≤ 656100

Show that y=cos(t)y=cos(t) is a solution to (dydt)2=1−y2(dydt)2=1−y2. Enter your answers below in terms of the independent varia

GrogVix [38]

Answer:

$(\frac{dy}{dt})^2=sin^2t$

Step-by-step explanation:

$y=cost$

DE : $(\frac{dy}{dt})^2=1-y^2$

If y is a solution of given DE then it satisfied the DE.

Differentiate w.r.t t

$\frac{dy}{dt}=-sint$

Using the formula

$\frac{d(cosx)}{dx}=-sinx$

LHS: $(\frac{dy}{dt})^2=(-sint)^2=sin^2t$

RHS

$1-y^2=1-cos^2t=sin^2t$

By using the formula

$sin^2t=1-cos^2t$

LHS=RHs

Hence, y is a solution of given DE

$(\frac{dy}{dt})^2=sin^2t$
