The name Quadratic<span> comes from "quad" meaning square, because the variable gets squared (like x</span>2<span>). However, it is important to not that an expression is only quadratic if and only if the highest degree of a term is 2. Therefore, the quadratic equations from the pool of choices would be as follows:
</span><span>3x^2 + 5x - 7 = 0
</span><span>5x^2+ 15x = 0
</span><span>x^2 - 4x = 4x + 7</span>
This should be g(x) = 12x - 8, as multiplying 3 by 4 increases the slope.
Answer:
Step-by-step explanation:
<u>Total cost of plant:</u>
<u>Greg makes total of:</u>
- 25*(2 + 0.75*2) + 18*(2 + 0.35*2) + (60 - 25 - 18)*2*4/5 = 163.3
<u>Since Greg mare than cost, he has a profit and the amount is:</u>
Answer:
for an infinite geometric series the formula for the sum of the infinite geometric series when the common ratio is less than one is given by
= 
= 144.
Step-by-step explanation:
i) from the given series we can see that the first term is 
= 120.
ii) let the common ratio be r.
iii) the second term is 20 = 120 × r
therefore r = 20 ÷ 120 = 
iv) the third term is 
= 20 × r
therefore r = 
÷ 20 =
v) for an infinite geometric series the formula for the sum of the infinite geometric series when the common ratio is less than one is given by
= = 144.
