Evaluate the following when a= 1 ,b=3,and c =27 ( a) 6a^2+ 2bc-2c^1/3

Dennis_Churaev [7]

Answer:

6a^2+ 2bc-2c^1/3 <u>= 162</u>

Step-by-step explanation:

a = 1
b = 3
c = 27

$\rm 6 {a}^{2} + 2bc - 2 {c}^{ \frac{1}{3} }$

$= 6 {(1)}^{2} + 2(3)(27) - 2( {27)}^{ \frac{1}{3} }$

$\rm = 6 + 162 - 2 ( \sqrt[3]{27} )$

$\rm = 168 - 2(3)$

$\rm = 168 - 6$

$\boxed{\rm = 162}$

The total charge that has entered a circuit element is q(t) = 6 (1 - e-7t) when t ≥ 0 and q(t) = 0 when t < 0. The current in

Bess [88]

Answer:

$A=42, B=-7$

Step-by-step explanation:

The current function of time is defined as follows:

$I(t)=\frac{dq(t)}{dt}$

where $q(t)$ is the charge function.

For the given charge function of time $q(t)=6\left( 1-e^{-7t}\right)$ we have the following current function:

$I(t)=\frac{d}{dt} \left(6\left( 1-e^{-7t}\right)\right)=42e^{-7t}$

In the problem it is proposed that $I(t)=Be^{-At}$ .

Examining the expression of $I(t)$ we obtained by deriving $q(t)$ with the expression proposed by the problem and comparing term by term:

$I(t)=Be^{-At}=42e^{-7t}$

We conclude that $A=-7$ and $B=42$ .

Holly bought a sweater on sale for 20% off the original price. If she saved $40, what was the original price?

spin [16.1K]

40 is 20% of 160, so if she saved 40$ and it was 20% off then the original price was 160$!!!
