Answer:
1). 2x^2-3x+20
2). 4x^2-14x+6
Step-by-step explanation:
1. (x-4)(2x+5)
FOIL:
(x)(2x)+5(x)-8(x)+(4)(5)
2x^2+5x-8x+20
=2x^2-3x+20
2. (4x-2)(x-3)
FOIL:
(4x)(x)-(3)(4x)-2(x)-2(-3)
4x^2-12x-2x+6
=4x^2-14x+6
Free points rights anyways can someone help me with this answer
A 85-kg is clown is fired from rest out of 480-kg cannon. If the clowns speed is 18 meters per second after the firing, then what is the recoil speed of the cannon? (Round your answer to the nearest tenth)
Answer:
The slope represents the cost per gallon for heating oil while the y-intercept represents the fee for heating oil.
She puts 8% of her salary in, so multiply her pay by 8% to get her yearly amount she saves:
45000 x 0.08 = $3,600 per year.
The company puts 6% of that in the account:
3600 x 0.06 = $216
So per year 3600 + 216 = $3,816 is saved.
3,816 x 2 = $7,632 is the 2 year total.
The answer is A.
Choice D is the correct answer.
For translations, moving to the right 5 units means you add 5 to x, and moving down 2 units means you subtract 2 from y. D is the only choice that accurately represents this.
Hope this helps
