A biologist is researching a newly-discovered species of bacteria. At time t = 0 hours, she puts one hundred bacteria into what

she has determined to be a favorable growth medium. Six hours later, she measures 800 bacteria.
The equation that can be used to model this growth would be:

A=100e0.35t
Use this formula to find how many bacteria to expect after a day at t=24

Answer:

Number 4: Using Pythagoras Theorem,

\sqrt{30^2+40^2} =50

Number 5:

\sqrt{41^2-40^2}=9

3:

\sqrt{11^2+60^2} =61 It is a right triangle

4:

\sqrt{9^2+37^2} =38.09 Not a right triangle

For the last one:

\sqrt{(\sqrt{20^2+6^2})^2+6^2} =2\sqrt{118}

Rounded down (because the answer needs to be a whole number) is 21

How do you Rewrite f(x) = −(x + 3)2 − 1 from vertex form to standard form?
wel
Expand it

-(x+3)^2-1
-(x+3)(x+3)-1
-1(x^2+3x+3x+9)-1
-1(x^2+6x+9)-1
-x^2-9x-9-1
-x^2-9x-10

f(x)=-x^2-9x-10

What is the solution to the system of equations? Use the substitution method. {y=−2x+53x−4y=2
klio [65]

y =  - 2x + 53x - 4y = 2 \\  y  = 51x - 4y = 2 \\  > y = 51 x - 4y \\  > 51x - 4y = 2
y = 51x - 4y \\ 5y = 51x \\ y =  \frac{51}{5} x
Substitute 51/5x into
51x - 4( \frac{51}{5} x) = 2 \\ 51x - 40.8x = 2 \\ 10.2x = 2 \\ x = 2 \times  \frac{10}{102}  \\ x =  \frac{10}{51}  \: aka \: 0.196
Substitute that into
y =  \frac{51}{5}  \times  \frac{10}{51}  \\ y = 2
Hope this helps. Answer should be correct. Unless your quadratic equation is wrongly stated.
