Can someone help me with this please

Mathematics
1 answer:
Vesnalui [34]3 years ago
6 0

Answer:

Step-by-step explanation:

It doesn’t say if x is a diameter or if the extended chord is a hypotenuse. I will assume so; it’s the only solution I can think of.

(x/2)^2 + (x/2 + 2)^2 = (7+5)^2

(x/2)^2 + 2x - 140 = 0

x = -2 ± 2√71

-2 - 2√71 Is an extraneous solution, so x = -2 + 2√71

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria. How many bacteria will there be on
spayn [35]

In this question, it is given that

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.

And we have to find number of bacterias on day *.

For that we use the following formula

N(t) =N_{0} (1 +r)^t

N(0)= 420, r = 0.18 , and \ t = 8days

Substituting these values in the formula, we will get

N(8)= 420(1+0.18)^8
\\
N(8)=1579

THerefore on day 8, number of bacterias are 1579.

What are these numbers in scientific notation ?
IgorLugansk [536]

Count how many places to the left you need to move the decimal point to get one digit to the left of the decimal point. That number of places is the exponent you use for the power of 10 when you write the number in scientific notation.

For example, 200. = 2.00×100 = 2.00×(10×10) = 2.00×10²

In scientifc notation, your numbers are

  • 5.7909×10⁷ kilometers
  • 1.082×10⁸ kilometers
  • 1.496×10⁸ kilometers
  • 2.2794×10⁸ kilometers
  • 7.7833×10⁸ kilometers
  • 1.4246×10⁹ kilometers
  • 4.4982529×10⁹ kilometers
