The temperature is at 34 degrees F each hour it decreases by 2 degrees until 3:00 AM. After 3 AM the temperature increases 3 degrees each hour until 7 AM. The temperature at 7 AM would be 44 degrees F.

It would be 40°F, the temperature drops down 2 degrees in one hour, and theres 3 hours til 3:00am, so it dropped 6° then it would 28°F, then it adds 3° every hour until 7:00am, which is 4 hours, so that would be 28°F+12°F= 40°F

What is the equation of the line that passes through the given point and is perpendicular to the given line?
Digiron [165]

Answer:

y= -1/15x + 16/15

Step-by-step explanation:

When two lines are perpendicular to each other that means their slopes are the negative reciprocals of each other.

So that means if a line has has a slope of 6, a line perpendicular to that line will have a slope of -1/6.

(a reciprocal is when the fraction is flipped over)

In this case, the negative reciprocal of 15 would be -1/15. So the slope of the line that is perpendicular would be -1/15.

The equation we would have so far for that line would be: y=-1/15x+b

Now we have to find the 'b' or the y intercept, which we can get by plugging in the point that was given (1,1), which is on that line.

Which gives us 1=-1/15(1)+b.

1=-1/15+b

1+1/15=b

Then you solve for b and get b= 16/15.

The equation of the line that is perpendicular to the given line is y= -1/15x + 16/15.

216 raised to the power 1/3 can also be written as cube root of 216. 

Changing the given expression to radical form, we can write:

(216)^{ \frac{1}{3} }  \\  \\ 
= \sqrt[3]{216}

216 is the cube of 6 i.e. multiply 6 three times (6 x 6 x 6), you will get 216.
So we can write the above expression as:

\sqrt[3]{(6)^{3} }

The cube root and cube cancel out each other, leaving the answer equal to 6.

So, the correct answer is option B

Find the final amount of $1000 investment after 9 years at 8% interest compound quarterly
wolverine [178]
Here's the equation for one year:
1000 + 0.08(1000)
But because it is 9 years:
1000 + 9(0.08(1000))
1000 + 0.72(1000)
We can make it simpler:
1.72(1000)
Multiply:
1720
You will have $1720
