Hi everyone I need to do this assignment for geometry and I have been stuck on it for days, the question is: "On a piece of paper, construct the initials of your first and last name using a compass and straightedge. Only parallel and perpendicular lines may be used in the construction, and both types of constructions must be demonstrated in your finished product. Do not erase arc markings made during the construction process as these help your instructor determine if the lines are constructed properly.", my initials are VG, but i dont even know how to start this, someone please help thank you!If anyone is taking geometry on flvs or already took it, the assignment I'm talking about is 01.04 Module One Quiz. I'm so lost!

How much would $100 invested at 8% interest compounded continuously be worth after 15 years?

Answers

The correct formula to use for continuous compounding is:
$A=Pe^(rt)$
where the exponential number e is the base of natural logarithms.
$A=100* e^{(0.08*15)=332.01$
So the amount after 15 years is $332.01

Answer:

$332.01 is correct via a p e x

What is an equation of the line that is perpendicular to y + 1 = -3(x - 5) and passes through the point (4, -6)?

Answers

Answer:

Option A.

Step-by-step explanation:

y + 1 = -3x + 15

y = -3x + 14

A line perpendicular would have a slope of 1/3.

y = 1/3x + c

-6 = 1/3 * 4 + c

4/3 + c = -6

c = -18/3 - 4/3

c = -22/3

So, we have y = 1/3x - 22/3.

y + 6 = 1/3(x - 4)

y + 6 = 1/3x - 4/3

y = 1/3x - 4/3 - 18/3

y = 1/3x - 22/3

So, the correct answer is Option A.

Hope this helps!

Len's recipe for blueberry muffins calls for 110.25 g of brown sugar for the muffin batter and an additional 55.45 g of brown sugar for the topping.Len wants to make 4.5 batches of muffins.

How much brown sugar will Len need?

Answers

110.25+55.45= 165.70(one muffin)
That means that we need to multiply 165.70 by (16.4)+8

Which simplified is 72x165.70= 11.930.4
which is the equivalent of 11kg 930 grams and 40 milligrams
