R=x²/y
x=3.8×10^5
y=5.9×10^4
work out the value of R in standard form.

Answers

Answer 1

Answer:

Answer:

$R=(14440000)/(5.9)$

Step-by-step explanation:

$R=(x^2)/(y)$

$x=3.8 \cdot 10^5$

$y=5.9\cdot 10^4$

$R=((3.8\cdot10^5)^2)/(5.9\cdot10^4)$

$=(2^(10)\cdot \:5^(10)\cdot \:3.8^2)/(2^4\cdot \:5^4\cdot \:5.9)$

$R=(2^6\cdot \:5^6\cdot \:3.8^2)/(5.9)$

$R=(14440000)/(5.9)$

Explaining step by step the simplest form of the expression 9r(r+3)-2r(r-4)

Answers

For simplest form, the first thing you'll want to do is get rid of the parentheses:

9r(r + 3) - 2r(r - 4) = 9r^2 + 27r - 2r^2 + 8r

Now we want to combine like terms:

9r^2 + 27r - 2r^2 + 8r = 7r^2 + 35r

This is about slope

Answers

Ok the slope question
We should definitely know the slope formula:

m=y₂-y₁/x₂-x₁

m= $(-2-2)/(-1-(-4))$
= $(-4)/(3)$

The slope of the line that passes through points (-4, 2) and (-1, -2) is $(-4)/(3)$

Please see the pic, I'd also solved it.
