Answer:

  3 6/7

Step-by-step explanation:

The nearest perfect squares are ...

  3² = 9

  4² = 16

Then an approximation of the root can be arrived at by linear interpolation.

  √15 ≈ 3 +(15 -9)/(16 -9) = 3 6/7 . . . . . where 16 and 9 are the nearest squares

Here's my step-by-step explanation:

We're just gonna factor.

If your teacher has spoken of FOIL, then he/she has probably said that it means First Outer Inner Last and that it helps with distributing problems like these.

Right, so let's get to it.

2x+3x^2 (4x-5)\\2x(4x-5)+3x^2(4x-5)\\2x(4x) + 2x(-5) + 3x^2(4x) + 3x^2(-5)

Can you see the FOIL method being spread out here? Let's keep going.

2x(4x) + 2x(-5) + 3x^2(4x) + 3x^2(-5)\\8x^2 + (-10x) + 12x^3 + (-15x^2)\\12x^3 + 8x^2 - 15x^2 -10x\\12x^3 -7x^2 -10x

Hope this helps, and let me know if I made a mistake! ^_^

Answer:

pls mark brainiest

 

The production possibilities frontier (PPF) is curved because the cost of production is not constant. If every trade-off were the same, it would create a straight line. But the direction that PPF is curved comes from the way that the trade-offs change

URGENT! PLZ HELP!!!!
EastWind [94]

Answer:

3.

Step-by-step explanation:

sin 32 / (1 + tan 45) * 6 / cos 58

= sin 32 / 2 * 6 / cos 58  ( since tan 45 = 1)

= 3 sin 32 / cos 58

Note sine 32 = cos (90 - 32) = cos 58, so we have:

= 3 sin 32 / sin 32

= 3.
