You sort of have this in the wrong place, but I'll answer it anyway. One of the things you need to do is use brackets so we know exactly what is going on. In this case, I think you mean e^(7x) and that is the way I will solve it.

Step One
Subtract 4.6 from both sides.
e^(7x) = 42.6 - 4.6
e^(7x) = 38.0             Take the ln of both sides.
ln(e^(7x)) = ln(38.0)
ln(e^(7x)) = 3.6376    Take down the 7x
7x * ln(e) = 3.6376     The ln(e) = 1
7x = 3.6376                Divide by 7
x = 3.6376 / 7
x = 0.5196 <<<<<<<<Answer

Explain the space race and how it affected America.
Umnica [9.8K]

When the Soviet Union launched Sputnik on October 4, 1957, it set off the space race with the United States.

Both countries wanted to be the dominant country when it came to Space and for America, this meant changing educational priorities.

STEM became the focus as young people were encouraged to use their mind to help get America further into the stars.

America spend quite a lot of money to land the first man on the Moon and eventually moved on to other priorities.

Which of the following scenarios would not be allowed in Rome after the Twelve Tables introduced the concept of equality before
sasho [114]
<span>The correct answer is D.The same evidence shows that both plebeian and a patrician committed assault. The plebeian is found guilty, while the patrician is found innocent.

Before they were introduced, there was no equality in front of the law when it came to different classes in the society. The situation in D describes how it would be before the law, while the twelve tables abolished this. Patricians and plebeians would now answer the same if proven guilty.</span>
