27/30 as a decimal I really need help with my homework. So please I'm struggling

patriot [66]

$Hello, \\ \frac{27}{30} = 0.9 \\ b/c, We-Had-To- Divide "27"from "30"$ but when you're trying to make a fraction into a decimal you have to divide the $numerator$ from the $denominator$ and that should $help$ you a $lot$

Write a function that represents the situation. Find the balance A in the account after the given time period t. $6200 deposit t

MaRussiya [10]

Answer:

$A=P(1+r)^t$
$\$7029.46$

Step-by-step explanation:

As this is the case of exponential growth, we can use the function

$A=P(1+r)^t$

Here A is function of t, where A gives the balance after time t.

P = initial deposit,

r = rate of change or rate of interest,

$6200 deposit that earns 8.4% annual interest compounded monthly for 18 months.

So,

P = $6200,

r = 8.4% annual = $\dfrac{8.4}{12}\%$ monthly = $\dfrac{0.084}{12}$ monthly (as interest compounded monthly)

t = 18 months,

Putting all the values,

$A=6200(1+\frac{0.084}{12})^{18}$

$=6200(1+0.007)^{18}$

$=6200(1.007)^{18}$

$=\$7029.46$

Cube root of - 1000p^12q^3

aleksley [76]

$\bf \sqrt[3]{-1000p^{12}q^3}~~
\begin{cases}
1000=10^3\\
(-1)^3=-1\cdot -1\cdot -1\\
\qquad -1\\
p^{12}=p^{4\cdot 3}\\
\qquad (p^4)^3
\end{cases}\implies \sqrt[3]{(-1)^3(10)^3(p^4)^3q^3}
\\\\\\
(-1)(10)p^4q\implies -10p^4q$

Find an equation of the line that passes through the points (1 2) and perpendicular to the line 2y-x=4

Ratling [72]

Steps to find the equation
1. Find the slope
2. Insert slope into the general equation
3. Find y-intercept
4. Insert -intercept into the equation found in step 2
And you get the equation of the line

----------------------------------------------------------------------------------------------
Find the slope
----------------------------------------------------------------------------------------------
2y - x = 4

----------------------------------------------------------------------------------------------
Rewrite into the form y = mx + c
----------------------------------------------------------------------------------------------
2y = x + 4
y = 1/2 x + 2

Slope = 1/2
Perpendicular slope = -2 (negative reciprocal)

----------------------------------------------------------------------------------------------
Insert slope into the equation
----------------------------------------------------------------------------------------------
y = mx + c
y = -2x + c

----------------------------------------------------------------------------------------------
Find y-intercept
----------------------------------------------------------------------------------------------
y = -2x + c
At point (1, 2)
2 = -2(1) + c
2 = -2 + c
c = 4

----------------------------------------------------------------------------------------------
Insert y-intercept into the equation y = -2x + c
----------------------------------------------------------------------------------------------
y = -2x + 4

----------------------------------------------------------------------------------------------
Answer: y = -2x + 4
----------------------------------------------------------------------------------------------
