Answer:
Well 7 x 10^-5 would mean you moved the decimal 5 Times because the power at the end of 10 is how many times the decimal is moved till it’s a number greater or equal to 1. So the scientific notation of that is: 0.00003
The -5 means that it was moved to the right. Positive always means left. Negative is always right.
Your answer would be
4.2
have a nice day!
good luck on your homework
Answer:
18
Step-by-step explanation:
Given
x - 1 = 2 ( add 1 to both sides )
x = 3
Then
2x² = 2(3)² = 2 × 9 = 18

What information does the zero of the equation 6 = –16x2 + 24x + 1 represent?In this case
</span><span> 0=-16x2+24x+1-6 .............> -16x2 +24x -5 = 0
</span><span>
If we graph the equation, we can see that the solutions are
x1 = 0.25 and x2 = 1.25
These points represent the moment when the ball is 6 ft above the ground(0.25 seconds after being thrown and 1.25 seconds after being thrown)</span>
4e^(2x) - 3 = 12
4e^(2x) = 15
e^(2x) = 15/4
taking logs
2x = ln (15/4)
x = ln(15/4) / 2
x = 0.66 to nearest hundredth
