Answer:

16.024

Explanation:

Using linear approximation:

We breakdown the numbers in order to solve thus:

[32(1 + 0.1875)]^0.8

= (32^0.8)*(1 + 0.001875)^0.8

= 16* (1 + 0.8*0.001875)

= 16*(1.0015)

= 16.024

Find the quotient 3 6/7 divided by 5/21

Snezhnost [94]

Answer:

81/5 or 16 1/5.

Step-by-step explanation:

First convert the mixed number to an improper fraction:

3 6/7

= (3*7 + 6) / 7

= 27/7.

So we have

27/7 / 5/21

Invert the second fraction and multiply:

= 27/7 * 21/5

= (27*21) / (7*5)

= (27*3) / 5 ( as 21/7 = 3)

= 81/5

= 16 1/5.

(-1 2/3) to the third power

Drupady [299]

Answer:

$-4\dfrac{17}{27}$

Step-by-step explanation:

We are asked to calculate the value of $-1\dfrac{2}{3}$ to the third power.

Now, $(-1\dfrac{2}{3})^{3}$

= $(-\dfrac{5}{3} )^{3}$

= $(-\dfrac{5}{3} ) \times (-\dfrac{5}{3} )\times (-\dfrac{5}{3} )$ { Since we know, a³ = a × a × a }

= $-\dfrac{5^{3} }{3^{3} }$ { Since the product of three negative numbers is also negative }

= $-\frac{125}{27}$

= $-4\dfrac{17}{27}$ ( Answer )

How many triangles are there that satisfy the conditions a =13, b =9, A = 62°?

8_murik_8 [283]

Answer:

Step-by-step explanation:

Alright, lets get started.

Using sin Law,

$\frac{sinA}{a}=\frac{sinB}{b}$

Plugging the value of a, b and angle A

$\frac{sin62}{13}=\frac{sinB}{9}$

$sinB=\frac{9*sin62}{13}$

$sinB=\frac{9*0.8829}{13}$

$sinB=0.61127$

taking sin inverse on both sides

$B=sin^{-1}(0.61127) =37.68$

The may be another value of B that will called B' = $180-37.68=142.32$

We will not consider this B' value because the um of angle B' and A will exceeds 180 degree ( $142.32+62=204.32$ )

Thats why only one triangle is possible. : Answer

Hope it will help :)

natulia [17]

Answer:

(-8, 135°)

Step-by-step explanation:

(8, -45°) has magnitude 8 and direction -45°.

If we add 180° to the direction and change the sign of the magnitude, we'll have the same point.

(-8, -45° + 180°) = (-8, 135°)
