So supplementary is an 180 angle and complimentary is 90 degree angle so that being said I could be wrong but that looks like a complimentary so a 90 degree angle it’s a 90 degree

P(a) = 2a -3; find p(a) = 15

Andrei [34K]

Since both is equal to p(a), you can set them as equal to each other:

15 = 2a - 3
18 = 2a
9 = a

Factor the expression. k2 – 100h2 (k 10h)(k 10h) (k – 10h2)(k 10) (k 10h)(k – 10h) h2(k 10)(k – 10)

Mars2501 [29]

$Use\ a^2-b^2=(a-b)(a+b)\\\\k^2-100h^2=k^2-10^2h^2=k^2-(10h)^2=(k-10h)(k+10h)$

Find an explicit rule for the nth term of a geometric sequence where the second and fifth terms are 36 and 2304, respectively.

poizon [28]

Answer:

$a_n=9(4^{n-1})$

Step-by-step explanation:

we know that

In a <u>Geometric Sequence</u> each term is found by multiplying the previous term by a constant, called the common ratio (r)

In this problem we have

$a_2=36\\ a_5=2,304$

Remember that

$a_2=a_1(r)$ -----> $36=a_1(r)$ -----> equation A

$a_5=a_4(r)$

$a_5=a_3(r^{2})$

$a_5=a_2(r^{3})$

Substitute the values of a_5 and a_2 and solve for r

$2,304=36(r^{3})$

$r^{3}=2,304/36$

$r^{3}=64$

$r=4$

Find the value of a_1 in equation A

$36=a_1(4)$

$a_1=9$

therefore

The explicit rule for the nth term is

$a_n=a_1(r^{n-1})$

substitute

$a_n=9(4^{n-1})$

school pennants cost 18$ each. ms lee says she will pay 146$ for 7 pennants. is her awnser reasonable

marshall27 [118]

No, because since each pennant cost 18$ then 7 pennants should cost 126$. So for Ms. Lee to pay 146$ is not reasonable.
