Find the exact value of csc 5pi/6

Leona [35]

Answer:

csc 2 (csc $\frac{5\pi}{6}$ = csc 150 = csc 30 = csc 2)

Step-by-step explanation:

csc $\frac{5\pi}{6}$ is in the 2nd Quadrant where only sin, and csc are positive.

csc $(\frac{5\pi}{6})=csc (\pi -(\frac{5\pi}{6}))=csc(\frac{5\pi}{6})$

but csc $\frac{5\pi}{6}$ = $\frac{1}{sin (\pi/6)} = \frac{1}{sin 30} = \frac{1}{1/2} =2$

Martin had 7 pounds of grapes left and gave away 2/5 of them explain how to use comparable numbers to estimate the amount of gra

OLga [1]

Answer:

See below

Step-by-step explanation:

<em>Compatible numbers</em> are numbers that are easy to use in mental arithmetic.

Martin gave away ⅖ of 7 lb of grapes, so the amount he gave away was

⅖ × 7 lb

⅖ is close to ²/₄ (½), and it is easy to take half of something mentally.

Half of 7 is about 3, so Martin gave away about 3 lb of grapes (the exact answer is 2.8 lb).

Answer:

11 m= 3 12 slope is 4 and y intercept is 2

Step-by-step explanation:

11 slope = gradient of a line formulae y2-y1 / x2 - x1

12-6 / 4-2 =3

12 slope is the gradient so and is found as m in the equation y=mx + c

so 4 is the slope and the y intercept is where x= 0 so y = 2
