How do you convert a percent into a decimal?

Mathematics

Leona [35]4 years ago

To do so, you would want to move the percents' decimal to the left twice. For example, to turn 75% to a decimal, you would move the decimal to the left twice turning 75% into 0.75

Suppose y=3t+5 and x=21t^2. Write a function of f(x) that determines y in terms of x. (Assume that t≥0)
Vadim26 [7]

Answer:

y=\sqrt{\dfrac{3}{7}x}+5

Step-by-step explanation:

Suppose y=3t+5 and x=21t^2.

Express t from the first equation:

3t=y-5\\ \\t=\dfrac{y-5}{3}

Substitute it into the second equation:

x=21\left(\dfrac{y-5}{3}\right)^2\\ \\x=21\cdot\dfrac{(y-5)^2}{9}\\ \\(y-5)^2=\dfrac{9}{21}x\\ \\y-5=\pm \sqrt{\dfrac{3}{7}x}

Since t\ge 0, then y-5\ge 0, so

y-5=\sqrt{\dfrac{3}{7}x}\\ \\y=\sqrt{\dfrac{3}{7}x}+5

Find dy/dx by implicit differentiation and evaluate the derivative at the given point.
Ray Of Light [21]
So, we have <span>xy=35
Since that, the first thing you should do is to </span><span>differentiate with respect to x
(look at the pic. 1), as you can see this is simply 1, which means you have to simplify 
Then we need to perform solving for </span> for dy/dx as we are about to get <span>the derivative of y with respect to x. pic.2
Get back to the oroginal function, now we can substitute this for y to get the func which will depend only on x pic.3
Then pic.4

Answer:

x=1

2x+3=5

-3 -3

now the three gets canceled and 5-3 is 2

2x=2

now divide 2 on both sides

2x÷2=2÷2

x=1
