Answer:

The electric field dE due to charge dQ is given as:

dE = (KdQ/r) * r^.

r^ is vector position

r^ = sqrt(x2 + a2). Pythagoras theorem.

K is electrostatic constant. K = 1/4πe(0)

Find the exact value of sin G

ad-work [718]

We need to find the value of the hypotenuse in order to solve this problem.

12^2+4^2=H^2

Therefore:

H=√(144+16)

H=4√10

Now:

sin(G)=O/H=4/(4√10)

=1/(√10)

=(√10)/10

4) Arnold ate breakfast at a restaurant. His total came to $76.75. There is an 8% sales tax and 15% tip. What is Arnold's total

lisov135 [29]

Answer:

The total cost is $95.32.

Step-by-step explanation:

Given:

Total came to $76.75. There is an 8% sales tax and 15% tip.

Now, to find the total cost.

<em>8% sales tax is there so we calculate the amount after adding sales tax:</em>

$76.75 + 8% of $76.75

$76.75+\frac{8}{100}\times 76.75$

$76.75+0.08\times 76.75$

$76.75+6.14$

$82.89$

The cost after sales tax is $82.89.

Now, <em>the cost after 15% tip:</em>

$82.89 + 15% of $82.89

$82.89+\frac{15}{100}\times 82.89$

$82.89+0.15\times 82.89$

$82.89+12.43$

$95.32$

The cost after the tip is $95.32.

Therefore, the total cost is $95.32.
