I don't know how to do this problem:
mariarad [96]

Answer:

3^3×3

81

3^7/3^3

Explanation:

First you should solve the expression you've got there.

(3^6×3^-4)^2

3^6= 3×3×3×3×3×3 the answer is 729

3^-4 A negative exponent means repeated division by the base. So for example 2^-4=1/(2^4)

=1/(2×2×2×2)= 1/16

3^-4= 1/(3^4)

=1/(3×3×3×3)

= 1/81 If you look up the answer in your calculator the answer that will show up will be 0.01234567901

So!

(729×0.01234567901)^2= 9^2

9^2= 81

Now you can look at the following expressions and whichever gives the answer 81 will be correct.

hope it helps!

Q7 Q26.) Find the quotient of the complex numbers and leave your answer in polar form.
irina [24]

To divide complex numbers in polar form, divide the r parts and subtract the angle parts. Or


<span><span><span><span>r2​</span><span>(<span>cos<span>θ2​ </span>+ i</span> sin<span>θ2​</span>) / </span></span><span><span>r1​</span><span>(<span>cos<span>θ1 </span>+ i</span> sin<span>θ1​</span>)</span></span></span>​</span> <span>= <span><span><span>r2/​</span><span>r1​</span></span>​</span><span>(cos(<span><span>θ2</span>−<span>θ1​) </span></span>+ i sin(<span><span>θ2​</span>−θ1)</span><span>)
</span></span></span>

z1/z2

= 3/7 (cos(π/8-π/9) + i sin(π/8 - π/9))

= 3/7 (cos(π/72) + i sin(π/72))

What is the area of a trapezoid if the base is 5, 17, 5 and height is 4
Genrish500 [490]

Answer:

44 units squared.

Step-by-step explanation:

The formula for area of a trapezoid is:

a  =  \frac{ b^{1} +  {b}^{2} }{2} h

a = missing area

b1 = short base (5)

b2 = long base (17)

h = height (4)

(5 + 17) ÷ 2 = 11

11 × 4 = 44

area = 44
