Answer:

A, C, E are not polynomials

Step-by-step explanation:

Identify the expressions that are not polynomials

A. x^2-(square root of x)-3

Polynomial cannot have a square root. so it is not polynomial

B. 4 - 3x + 5x^6

C. 5x^1/2 + 4x^2

A polynomial does not have fractional exponent

D. 14x^7

E. x^2-x-12/x+3

Polynomial cannot have x in the denominator

F. 8x^10 + 2x^5

Which geometric series converges?

kvv77 [185]

Answer:

Option (1)

Step-by-step explanation:

In a geometric series,

$\sum_{n=0}^{\infty}ar^n=a+ar^1+ar^2+....$

Here r = $\frac{a_n}{a_{n-1}}$

For |r| < 1, series will converge.

For |r| > 1, series will diverge.

Option (1)

Given geometric series is,

$\frac{1}{2}+\frac{1}{4}+ \frac{1}{8}+ \frac{1}{16}.......$

Common ratio = $\frac{\frac{1}{4}}{\frac{1}{2} }$

= $\frac{1}{2}$

Since, $\frac{1}{2}$

Series will converge.

Option (2)

$\frac{1}{2}+1+2+4+......$

r = $\frac{1}{\frac{1}{2}}=2$

Since, 2 > 1,

Series will diverge.

Option (3)

$\frac{1}{2}+ \frac{3}{2}+ \frac{9}{2}+ \frac{27}{2}+......$

Common ratio 'r' = $\frac{\frac{3}{2} }{\frac{1}{2} }=3$

Since, 3 > 1,

Series will diverge.

Option (4)

$\frac{1}{2}+3+18+108+.....$

Common ratio 'r' = $\frac{3}{\frac{1}{2}}=6$

Since, 6 > 1

Series will diverge.

Therefore, Option (1) will be the correct option.

Juan dimes received a single payment loan from his loan for $4,000. he agreed to repay the loan in 90 days at an interest rate o

AVprozaik [17]

9514 1404 393

Answer:

Step-by-step explanation:

The amount due is ...

A = P(1 +rt)

where P is the amount borrowed, r is the annual rate, and t is the number of years. For "exact interest", we use 365 days in a year, so the number of years is 90/365.

A = $4000(1 + 0.085×90/365) ≈ $4083.84

Juan's loan will have a value of $4083.84 at maturity.

Answer:

Part A

Part B

176

Step-by-step explanation:

Total: 65+110+75 = 250

P(O) = 75/250 × 100 = 30%

P(A) = 110/250 × 100 = 44%

P(K) = 65/250 × 100 = 26%

Apple juice:

44% of 400

44/100 × 400

A wall shaped like a trapezoid needs to be painted. the height of the wall is 16 feet and the bases are 20 feet and 24 feet. if

AURORKA [14]

Area of Trapezoid = h(b1+b2/2)
b1 and b2 are the lengths of each base and h is the height.

Area = 16(20+24/2)=352 Square Feet

352/20=17.6 Cans of paint.

Hope this helps and is correct, I haven't done this kind of math in a while.
