19) because 1/2 an hour is 8 miles, 1 hour will take 16 miles , multiply 8 by 2 because I️t gave half an hour so multiplying by 2 will give an hour (2 half’s make a whole)

20) 2 1/2 multiplied by 4 is 10, so his jog will be 10 minutes longer

21) 4,500 was what he earned and 4,900 was what he lost (“expenses”) so he lost $400:
$4,500 - $4,900= -$400
He lost money because the answer is negative

Given the functions k(x) = 2x2 − 5 and p(x) = x − 3, find (k ∘ p)(x). (k ∘ p)(x) = 2x2 − 6x 4 (k ∘ p)(x) = 2x2 − 12x 13 (k ∘ p)(

jeka57 [31]

$(k \circ p)(x)=k(p(x))=k(x-3) \\ \\ =2(x-3)^2-5 \\ \\ =2(x^2 - 6x+9)-5 \\ \\ =\boxed{2x^2 - 12x+13}$

Answer:

Step-by-step explanation:
