1 Mathematicians often study equations of the form x' (t) = rx(t)[1 – X(t)], instead of the more complicated x"(t) = cx(t)[K – X(t)), justifying the simplification with the statement that the second equation "reduces to" the first equation. Starting with y' (t) = cy(t)[K – y(t)], substitute y(t) = Kä(t) and show that the equation reduces to the form x'(t) = rx(t)[1 – x(t)]. How does the constant r relate to the constants cand K?

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
