A: How many text messages would you have to send or receive in order for the plans to cost the same each month?
Answer: 100
Step-by-step:
$.20x100=$20
$40+$20=$60
b: If you send or receive an average of 50 texts each month, which plan would you choose?Why?
Answer: A
Because $.20x50=$10
$40+$10=$50
Answer:
I believe it's 15 (3x+5)
Step-by-step explanation:
15 times 3 is 45 and 15 times 5 is 75
Please write this polynomial as P(x) = <span>-2x^4+24x^2-10, using " ^ " to denote exponentiation.
This is a fourth degree polynomial, since the highest power of x is 4. Ordinarily, a fourth degree poly would have 5 terms, but here two of the coefficients of the powers of x are zero, leaving only 3 terms.
</span>The lead coeff. of P(x) = -2x^4+24x^2-10 is -2.
The constant terms is -10. The exponent of x here is zero (0).
The degree of the middle term is 2 (see 24x^2, above)
Would you please post your other questions separately. Thank you.
Keep dividing by 3 to get the rest of the answers.
If you are considering all the vertices independently you will have a total of 8*10 = 80 triangles. You can figure out this way: the sum of the interior angles of a decagon = (2n-4)*right angles or (n-2)*triangles. So a decagon will form 8 triangles.
hope this helps...
