Sqrt(24 - 5 - 8) = sqrt(11), which is irrational as 11 isnt a square number

350 at 5% interest for 4 years simple interest at the to the nearest cent

Scilla [17]

The answer is $4.40

mutiply 350 by 5% and get 17.5 then divide thag by 4 and you get 4.37 and you supposed to round it up which will be 4.40

Test the series for convergence or divergence (using ratio test)

Triss [41]

Answer:

$\lim_{n \to \infty} U_n =0$

Given series is convergence by using Leibnitz's rule

Step-by-step explanation:

Step(i):-

Given series is an alternating series

∑ $(-1)^{n} \frac{n^{2} }{n^{3}+3 }$

Let $U_{n} = (-1)^{n} \frac{n^{2} }{n^{3}+3 }$

By using Leibnitz's rule

$U_{n} - U_{n-1} = \frac{n^{2} }{n^{3} +3} - \frac{(n-1)^{2} }{(n-1)^{3}+3 }$

$U_{n} - U_{n-1} = \frac{n^{2}(n-1)^{3} +3)-(n-1)^{2} (n^{3} +3) }{(n^{3} +3)(n-1)^{3} +3)}$

Uₙ-Uₙ₋₁ <0

Step(ii):-

$\lim_{n \to \infty} U_n = \lim_{n \to \infty}\frac{n^{2} }{n^{3}+3 }$

$= \lim_{n \to \infty}\frac{n^{2} }{n^{3}(1+\frac{3}{n^{3} } ) }$

= $= \lim_{n \to \infty}\frac{1 }{n(1+\frac{3}{n^{3} } ) }$

$=\frac{1}{infinite }$

$\lim_{n \to \infty} U_n =0$

∴ Given series is converges

Can someone please help me solve this, thank you so much if u help!

malfutka [58]

Answer:

68°

Step-by-step explanation:

The triangle containing the 79° angle is isosceles. That means the other base angle is also 79°. The central angle is ...

V = 180° -2(79°) = 22°

Angle X is the other acute angle in right triangle VWX, so has measure ...

X = 90° -22° = 68°

_____

Additional comment

A tangent makes a right angle with the radius to the point of tangency. W is the point of tangency, so angle VWX is a right angle.

HELP PLSSSS I DONT UNDERSTAND WALLAH

Harlamova29_29 [7]

Answer:

7.2

Step-by-step explanation:

Distance between (4, 3) and (8, 9):

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(8 - 4)^2 + (9 - 3)^2}$

$d = \sqrt{(4)^2 + (6)^2}$

$d = \sqrt{16 + 36}$

$d = \sqrt{52} = 7.2$ (nearest tenth)
