Answer: D and B
Step-by-step explanation:
Starting from a velocity of 0, your change in velocity over a period of 6 seconds will be ...
... (9.8 m/s²)×(6 s) = 58.8 m/s . . . . . downward, since you are "falling"
_____
Note the units of seconds in the time period cancel one of the factors of seconds in the acceleration to leave only seconds in the denominator of the result. That is confirmation that the proper math operation is being carried out, since the units of velocity are meters per second.
The correct equation is P(t) = Po*e^(kt). Please enclose "kt" inside parentheses and use the " ^ " symbol to indicate exponentiation.
"k" is the growth constant, which here is 0.017. "t" is the number of yeasrs. P(7) is the population after 7 years. Po is the initial population, which in this case is 91 million.
The initial value, when t = 0, is 91 million.
After 7 years, the population, P(7), was P(7) = (91 million)*e^(0.017*7). This evaluates to P(7) = (91 million)*(1.070) = 96 million
Answer:
TRUE
Step-by-step explanation:
The triangles PTQ and RTS are similar; so the ratios of corresponding sides are equal.
Let us denote the unknown length SQ as x.
We could make the following similarity relation;
Cross multiply to obtain;
Therefore;
Therefore, the answer is option A
