barxatty [35]3 years ago

Answer:

80°

Step-by-step explanation:

In the ratio 2:3:4, the largest value corresponds to the largest angle. The sum of the ratio is 2+3+4=9.

The sum of angles in a triangle is 180°. Then x is given by

x = \dfrac{4}{9}\times 180^\circ = 80^\circ

Find the first and second derivative of the function defined by the parametric equation.
Sergeu [11.5K]

Answer:

Step-by-step explanation:

Given two parametric equations x(t) and y(t), the first derivative can be found using the following equation:

\frac{dy}{dx} = \frac{\frac{dy}{dt}}{\frac{dx}{dt}}

In this problem, x(t) = 3e and y(t) = 3^{3t} - 1. Finding the derivative of each of these functions with respect to t gives us the following:

\frac{dx}{dt} = 0

\frac{dy}{dt} = 3^{3t + 1}\log{3}

Because \frac{dx}{dt} = 0, that means the function is a vertical line and has an infinite first derivative.

4) <u>Cellular Organization:</u> Each Cell must perform their duty, or else the cat would die

5) <u>Homeostasis:</u> Each cat must have an equilibrium, such as balance, balance of temperature of cat vs. the nature, etc.

If you invest $100 into an account that earns 9% interest each year, how many years will it take for you to have $200?
Helga [31]
It does not say simple or compound interest.
Simple interest is rarely used these days, so assume compound.
Use the standard formula:
future value = present value*(1+rate/n)^(nt)
n=number of times interest is compounded per year (=1)
t=number of years
Plugging values,
200=100(1.09)^t
1.09^t = 2
take log
t(log(1.09))=log 2
t=log(2)/log(1.09)=0.6931/0.08618=8.04 years.
