The science of physics, specifically projectile motion, goes hand in hand with the mathematics of trigonometry. We need the math

of trigonometry to model the flight path of an object moving through the air. Describe another connection between a math topic and a non-math topic, where the math topic is needed to explain and model the non-math topic.

If we want to calculate the time it takes to fill a water tank, we need the flow and volume of the tank.
 The flow must be a data, but for the volume of the tank we need mathematics.
 For example, if it is a cylinder, we need mathematics to know that the volume of the cylinder is:
 V = pi * r ^ 2 * h

F(x)=2x^2+4x-16<br> g(x)=4x^2-16<br> Find (f/g)(x).
Nastasia [14]

Answer:

Step-by-step explanation:

(\frac{f}{g} )(x) = \frac{2x^{2} +4x-16}{4x^{2} -16}

2x²+4x -16 =  2(x²+2x-8); factor 2

                  = 2(x+4)(x-2) ;factor the quadratic equation

4x²-16  = 4(x²-4) ; factor 4

            =4(x²- 2²) ; rewrite 4 as 2²

           = 4(x-2)(x+2); now use the difference of two squares a²-b²=(a-b)(a+b)

so now we have:

(\frac{f}{g}) (x) = \frac{2(x+4)(x-2)}{4(x-2)(x+2)} ; simplify (x-2) from numerator and denominator

                                  and 2/4 as 1/2

(\frac{f}{g}) (x) = \frac{(x+4)}{2(x+2)}

Pls answer for branietest
wolverine [178]

Answer:

3 5/7

subtract the 3/7

4 3/7 - 3/7 = 4

4 = 28/7

28/7 - 2/7 = 26/7

26 /7 = 3 remainder 5 so 3 5/7

the whole number is the answer and the remainder is the numerator

3 5/7 is the answer

Hope this helps

Aliens have injected Ana with mathematical nanobots. These nanobots force Ana to think about math more and more. Initially, ther
natulia [17]

Answer:

<em>Math will take over Ana's brain at 4.4 hours</em>

Step-by-step explanation:

<u>Exponential Grow </u>

The population of the nanobots follows the equation  

p(t) = 5\cdot 2^t

We must find the value of t such that the population of nanobots is 106 or more, that is

5\cdot 2^t\geq 106

We'll solve the equation

5\cdot2^t= 106

Dividing by 5

2^t= 106/5=21.2

Taking logarithms

log(2^t)= log(21.2)

By logarithms property

t\cdot log(2)= log(21.2)

Solving for t

\displaystyle t=\frac{log21.2} {log2}

t=4.4 \ hours

Math will take over Ana's brain at 4.4 hours
