______________________________

<h3>1.) Turn each fraction into a decimal:</h3>

$1\frac{1}{2}=1.5$

$2\frac{3}{4}=2.75$

$3=3$

$2\frac{3}{4}=2.75$

$2\frac{1}{2}=2.5$

$2\frac{3}{4}=2.75$

$3\frac{3}{4}=3.75$

$3=3$

$3\frac{1}{2}=3.5$

$2\frac{1}{2}=2.5$

$3\frac{1}{2}=3.5$

Express the limit as a definite integral on the given interval. lim n→[infinity] n xi ln(1 + xi2) Δx, [2, 7] i = 1

xenn [34]

Answer:

Step-by-step explanation:

$Consider \ the \ following \ series$

$\lim_{n \to \infty} \sum \limits ^n_{i=1} x_i \ In ( 1+ x_i^2) \Delta x , [2,7]$

$Let's \ recall \ the \ explanation \ of$ d $efinite$ $\ integral \ in \ terms \ of \ Riemann \ sum$

$\int^b_a \ f(x) \ dx = \lim_{n \to \infty} \sum \limits ^n_{i=1} \ f(x_i) \Delta x , \ where \ \Delta x = \dfrac{b-a}{n}$

$By \ efinition, \ the \ limit \ is \ then \ expressed \ as \ integral$

$\lim_{n \to \infty} \sum ^a_{i=1} \ x_i \ In (1+x_i^2) \Delta x = \int^7_2 xIn (1+x^2) \ dx$

PLEASE HELP On a clock, what is the angle formed by the hour hand and minute hand at 1:30? Assume the hour and minute hand each

SpyIntel [72]

Answer:

D. 135°

Step-by-step explanation:

Time is 1:30

The minute hand traveled half of full circle

The minute hand position is:

360°×1/2= 180°

The hour hand traveled 1.5 hr ÷ 12 hr= 1/8 of full circle

The hour hand position is:

360°×1/8= 45°

the difference between the hands:

180°-45°= 135°

Choice D. 135° is the correct one
