Answer:
C. 2.5×10^-27
Step-by-step explanation:
(2×10^-13)^-2 = 2^-2 × 10^(13×(-2)) = 1/4 × 10^-26
= 0.25 × 10^-26 = 2.5 × 10^-27
___
Your scientific or graphing calculator can compute and display this for you.
Answer:
Substitute y=x-2y=x−2 into y=-0.5x+4y=−0.5x+4.
x-2=-0.5x+4x−2=−0.5x+4
2 Solve for xx in x-2=-0.5x+4x−2=−0.5x+4.
x=4x=4
3 Substitute x=4x=4 into y=x-2y=x−2.
y=2y=2
4 Therefore,
\begin{aligned}&x=4\\&y=2\end{aligned}
x=4
y=2

Answer:</h3>
- sticker: $12,620
- dealer's cost: $10,712
<h3>
Step-by-step explanation:</h3>
The total cost of options is the sum of their individual costs.
total options = $542 +140 +318 +580 = 1580
The sticker price is ...
sticker price = base price + total options + destination charge
= $10600 +1580 +440
sticker price = $12,620
The dealer cost is ...
dealer cost = 82% × base price + 100% × total options + destination charge
= 0.82·$10600 +1580 +440
dealer cost = $10,712
Standard form is ax^2+bx+c=0
First evaluate the exponent and expand (foil).
y= 3(x^2-4x+4)+1
Then distribute the 3
y= 3x^2-12x+12+1
Combine like terms
y=3x^2-12x+13
Final answer: 3x^2-12x+13=0
Trial and error specifies that you should guess the value of m and see if you aimed too low too high then adjust your next guess based on that.
Suppose we don't already know what m is (even though it is completely obvious), let's pick m to be 6,
So we check, 
but 
which means m must be bigger.
So we pick m to be 8 and check, 
but 
which means m must be smaller.
Since only natural number between 6 and 8 is 7 we pick m to be 7 and check, 
and 
.
The answer is therefore 7.
Hope this helps :)
