Angles 2,3, and 5 are exterior angles because they are on the outside of the parallel lines that are cut by a transversal.

Answer: $\bold{a)\ P(t)=P_o\cdot e^{t\cdot ln(2.7)}}$

b) 5314

c) ln 2.7

d) 4.6 hrs

<u>Step-by-step explanation:</u>

$P(t) = P_o\cdot e^{kt}\\\\\bullet \text{P(t) is the number of bacteria after t hours} \\\bullet P_o\text{ is the initial number of bacteria}\\\bullet \text{k is the rate of growth}\\\bullet \text{t is the time (in hours)}\\\\\\270=100\cdot e^{k(1)}\\2.7=e^k\\ln\ 2.7=\ln e^k\\\boxed{ln\ 2.7=k}\\\\\text{So the equation to find the number of bacteria is: }\boxed{P(t)=P_o\cdot e^{t\cdot ln(2.7)}}\\\\\\P(4)=100\cdot e^{4\cdot ln(2.7)}\\.\qquad =\boxed{5314}$

$10,000=100\cdot e^{t\cdot ln(2.7)}\\100=e^{t\cdot ln(2.7)}\\ln\ 100=ln\ e^{t\cdot ln(2.7)}\\ln\ 100=t\cdot ln(2.7)\\\dfrac{ln\ 100}{ln\ 2.7}=t\\\\\boxed{4.6=t}$

1. The formula for the velocity of an object is d=v/t, where v is the object, d is the distance traveled, and t is the time the

Arlecino [84]

Answer:

you need to isolate t or time

you need to know distance between sun and earth and velocity of them in order to calculate how long it takes for light to travel from the Sun to Earth

Step-by-step explanation:

$t*(d)=(v/t)*t\\td= v\\\\\frac{td}{d} =v/d \\t=v/d$

to find time you multiply t to both sides then you cancel t from where velocity is and you get velocity by itself

now you mulipy d to both side to get v over d and time by itself

Im notr sure but if we take the chances that the 4 sum has to be either (1.3) (3.1) (2.2) (2.2) that means its chance is 4/36 for each roll which is also 1/9 ,, we can multiply 1/9 times the roll times ( 252 ) we get =28
