2^24 = 16,777,216 bacterias.
Step-by-step explanation:
So we start with 1 bacteria
after 1 hours: 2*1 = 2
after 2 hours: 2*2 = 2^2 = 4
after 3 hours: 2*2^2 = 2^3
after n hours: 2^n
Since one day has 24 hours we have n = 24 and total number of bacteria will
be: 2^24 = 16,777,216 bacterias.

DochEvi [55]

Answer:

25% of students voted for the athlete

Step-by-step explanation:

First you need to know how many students are in total. In this case there is 60, 15+45

Then you write it as a fraction

\frac{15}{60}

because 15 voted for athlete out of the 60 students.

After this you need to divide 15÷60 which is . 25 then you transform that number into a percent which is 25%

Answer:

x>-5

Step-by-step explanation:

\frac{-1}{5} x+1

Subtract 1 from both sides

\frac{-1}{5} x+1-1

Simplify

\frac{-1}{5} x

Multiply both sides by -1, which reverses the inequality also

\frac{-1}{5} x(-1)>1(-1)

Simplify

\frac{1}{5} x>-1

Multiply both sides by 5

5*\frac{1}{5} x>5(-1)

Simplify

x>-5

Aleks [24]

Answer: Relative error = 50%

Step-by-step explanation:

Relative error Re = Absolute error/True value × 100%

True value = 2 scoops

Measured(used) value = 3 scoops

Absolute error Ae = measured(used) value - True value

= 3 scoops - 2 scoops

Ae = 1 scoop

Re = 1/2 × 100%

Re = 50%

Which conic section does this equation represent?
nadya68 [22]

Answer:

Hyperbola

Step-by-step explanation:

x^2-4x-y^2+6y-9=5

Lets write variables in square form using completing the square method

LEts group x  and y terms

(x^2-4x)+(-y^2+6y)-9=5

y^2 terms should be positive always, so we pull out negative sign from y^2

(x^2-4x)-(y^2-6y)-9=5

We have negative sign in the middle. so we will get equation in the form of

\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} =1

If we have negative sign in the middle then it is an hyperbola
