What is a minimum - pre cal

UkoKoshka [18]

Answer: y-value of the vertex of a ∪-shaped (positive) parabola

Step-by-step explanation:

For a quadratic: it is the y-value of the vertex of a positive parabola.

If it is a negative parabola ( ∩-shaped), it is the maximum.

For a cubic: it is the y-value of all of the vertices of the ∪-shaped sections of the graph. These are typically referred to as the "relative minima" when given an interval.

Help me out on this, ASAP!!! (Geometry) Write formal proofs using the HL Theorm.

xxMikexx [17]

Answer:

Given PR is perpendicular to QS, and PQ and PS are congruent. Angle PRQ and angle PRS are right angles by the definition of perpendicular segments. Therefore triangle PRQ and triangle PRS are right triangles. Segment PR is congruent to segment PR by the reflexive property of congruence. By the HL Theorem, triangles PRQ and PRS are congruent.

Bacteria in a culture increase at a rate proportional to the number of bacteria present. An initial population of 300 triples in

beks73 [17]

Answer:

After 24 hours, there will be 4191 bacteria present in the culture.

Step-by-step explanation:

Initial number of bacteria = 300

amount in 10 hrs = 3 x 300 = 900

time taken = 10 hours

Bacterial growth is exponential, ans so we use the equation

N = N' $e^{kt}$

where N is the final amount

N' is the initial amount

k is the growth constant

t is the time

For this first case, we have

900 = 300 x $e^{k*10}$

3 = $e^{10k}$

take natural log of both sides, we'll have

ln 3 = ln $e^{10k}$

1.0986 = 10k

k = 1.0986/10 = 0.10986

using the growth constant above, we calculate for a day which is 24 hours

N = N' $e^{kt}$

N = 300 x $e^{0.10986*24}$

N = 300 x $e^{2.637}$

N = 300 x 13.97

N = 4191 bacteria
