The product of two numbers is -30, but their sum is -13. What are these two numbers?

Nata [24]

<h3>Answer: -15 and 2</h3>

You find this through trial and error.

A much more efficient way is to solve x^2-13x-30 = 0 using the quadratic formula. You'll find the two solutions to be x = 15 and x = -2

Going from those solutions, we get x-15 = 0 and x+2 = 0 which then turn into (x-15)(x+2) = 0 through the zero product property.

Please Help! It is Pre-Calc and I need to know the answer!

Kisachek [45]

That's again the derivative at 2, so the answer is A. 4. Hard way:

f(x)=x²

f(2)=4

f(2+h) = (2+h)² = 4 + 4h + h²

f(2+h) - f(2) = 4h + h²

(f(2+h)-f(2))/h = 4 + h

Limit is 4.

Given that the circumferential of a circle is 22cm calculate its diameter

Ipatiy [6.2K]

Answer:

diameter =7 cm

Step-by-step explanation:

circum=2pi×r

$2\pi \times r$

2×pi×r=22

2×22÷7×r=22

r=22×7÷44

r=7÷2

r=3.5

d=2×r=2×3.5=7
