Answer:

The answer is that Regina is absolutely right

Step-by-step explanation:

Hello!

The answer is that Regina is absolutely right, this is because the fundamental theorem of algebra states that every polynomial equation has the same number of solutions as its highest exponent, for this case it is 2. Therefore, there are two values of X that cause the equation to result in zero

galina1969 [7]

Answer: You can send or receive a maximum of 21 text messages per month.

Step-by-step explanation:

First, you need to take out the number the phone bill costs (24.99)

29 - 24.99 = 4.01

Then, you need to find out how many 0.19 fit into 4.01.

21 * 0.19 = 3.99. Any more than that and it would go over.

Two less than 3/2 of a <br> number (x) is no more than 5 1/5
alexandr402 [8]
3/2 of a number could be 3/2x. two less than is thus 3/2x-2. no more than means less than or up to or ≤. finally,

3/2x-2≤5 1/5
3/2x≤26/5+10/5
3/2x≤16/5
x≤16/5*2/3
x≤32/15. or x ≤ 2 2/15

Given the Arithmetic sequence A1,A2,A3,A4A1,A2,A3,A4
Bad White [126]
The given sequence is
a₁ = 29
a₂ = 39
a₃ = 49
a₄ = 59

This sequence is an arithmetic sequence. Th first term is a₁ = 29, and the common difference is d= 10.

The n-th term is
a_{n}=a_{1}+(n-1)d
The 33-rd termis
a₃₃ = 29 + (33 - 1)*10
     = 29 + 320
     = 349

Answer: a₃₃ = 349

At 22 years of age, Nicolas and Troy have started their first full-time jobs, and Troy decides to place $10,000 in a savings pla
grigory [225]

Answer:

The correct answer 8486.

Step-by-step explanation:

Given:

Troy - P pr principle amount = 10000

rate = 9%

time = 60-22 = 38

intrest at every three months so time = t = 38*4 = 132

Nicohlas

P = x

rate = 10%

time = 60 -45 = 15

every month compounded = 15*12=180

solution:

the formula of compound intrest = P (1 + r/n)^(nt)

where n = number of counded intrests per year

puting formula for troy=

10000 (1+9/4)^132

= 294,322.96 .....1

now for nicolas

I = x(1+10/12)^180

x = 294,322.96/(1+10/12)^180

= 8486.
