Answer:
Step-by-step explanation:
Let x represent the number of calls made with plan 1 in a month.
Let y represent the number of calls made with plan 2 in a month.
Plan 1 charges $25 per month for unlimited calls. This means that the total cost of x calls made with plan 1 in a month would be $25
Plan 2 charges $15 per month plus $0.04 per call. This means that the total cost of x calls made with plan 1 in a month would be
15 + 0.04x
a) for the number of calls for which Plan 1 is more economical than Plan B, it becomes
25 < 15 + 0.04x
25 - 15 < 0.04x
10 < 0.04x
0.04x > 10
x > 10/0.04
x > 250
b) plan 1 would be more economical when the calls per month exceed 250.
1.304 x 10⁰ = 1.304 x 1 = 1.304
1.304 x 10¹ = 1.304 x 10 = 13.04
1.304 x 10² = 1.304 x 100 = 130.4
1.304 x 10³ = 1.304 x 1,000 = 1,304
1.304 x 10⁴ = 1.304 x 10,000 = 13,040
1.304 x 10⁵ = 1.304 x 100,000 = 130,400
1.304 x 10⁶ = 1.304 x 1,000,000 = 1,304,000
1.304 x 10⁷ = 1.304 x 10,000,000 = 13,040,000
1.304 x 10⁸ = 1.304 x 100,000,000 = 130,400,000
* 1.304 x 10⁹ = 1.304 x 1,000,000,000 = 1,304,000,000 *

ANSWER:
1.304 x 10⁹ = 1.304 x 1 Billion
We know that
<span>Trinomial of degree 35 means a polynomial
that
a) Having three terms
b) highest degree is 35
examples
x</span>^35+x³+3
x^35+2x-8
x^35+x²+2
etc
27 is 15% of 180
(15/100)*x=27
x=27 / (15/100)
x=(27 * 100) / 15
x=180
