Answer:
3*10^5 or 300,000 cant remember witch one it is
Step-by-step explanation:
1.5*10^2= 150
2*10^3=2,000
150*2000=300,000
3*10^5

Answer:
30 cm²
Step-by-step explanation:
A = bh/2
A = (12 cm)(5 cm)/2
A = 30 cm²
The answer
the full question is
If A(x1, y1), B(x2, y2), C(x3, y3), and D(x4, y4) form two line segments, and AB ⊥ CD, which condition needs to be met to prove AB ⊥ <span>CD?
</span>
let be A(x1, y1)B(x2, y2) the first line, and C(x3, y3) D(x4, y4) the second
the slope of the first line is m = y2 -y1 / x2 - x1
the slope of the second line is m' = y4 -y3 / x4 - x3
so the condition needs to be met to prove AB ⊥ CD is
y2 -y1 y4 -y3
m x m' = --------- x ------------ = -1
x2 - x1 y4 -y3
Answer:
C. 0.0067
Step-by-step explanation:
6.7*10^-3
Write in standard form.
This question pertains to scientific notation, a way to easily express really large or really small numbers.
You'll first notice that 10 has a negative exponent. This tells you that the number is going to be smaller than 10.
This is because 10^-3 translates to 1/10^3 based on exponent rules
With that, you know that your equation is 6.7/10^3
<u>You can simplify that to:</u>
0.0067
In case you didn't know how I got there, 10^3 simply means 10 multiplied by itself 3 times.
The other method would be to look at your answer choices. Since we have a negative exponent, we can eliminate D.
Next, since we have a positive coefficient (6.7), we can eliminate A and B.
That leaves us with the answer C. 0.0067
