what is the value of z for the equation fraction 1 over 3z = −fraction 5 over 6 fraction 1 over 6z? 5 2 −2 −5

The Answer is 0. Because
First you simplify 1/6 = 5/6 (Z+ 1/6)=0
Then use the 6 as a denominator = Z=Z/1= z.6/6
Then you need to add to the common denominator: z.6 +1/6= 6z+1/6
5/6- (6z+1)/6= 0

Hello can someone help me with these four questions!!!

True [87]

Answer:

1) A = 27 square units, P = 24 units; 2) 276 mm; 3) A = 8, B = 4, C = 3, D = 5, 108 square feet; 4) 5.

Step-by-step explanation:

1) The sides of the rectangle are 9, 9, 3, and 3.

2) 40 + 40 + 70 + 70 + 28 + 28

3) 32 + 6 + 6 + 24 + 40 = 108

4) 24 + 24 + 20 + 20 + 30 + 30 = 148

740/148 = 5

Evaluate the following integral over the specified region. Assume (r comma theta )(r,θ) are polar coordinates. ModifyingBelow In

topjm [15]

Answer:

Step-by-step explanation:

We have to integrate the function

$16+x^2+y^2$ over the region

$1\leq r\leq 3\\0\leq \theta \leq \pi$

Let us convert into polar coordinates

x=cost : y = sint

Then we get dxdy = rdr dt

So we get the integral as

$\int \int _R (16+x^2+y^2)^2 dxdy\\= \int\limits^3_0 \int\limits^\pi_0( {16+r^2}^2) (r)drdt\\ =(t) (\frac{(16+r^2)^3}{6}$

Substitute the limits to get

Answer

= $(\pi-0) [\frac{1}{6} (25-16)\\=1.5 \pi$

If f(x) = 2x + 1, and<br> g(x) = x - 3, then<br> f(g(x)) = [ ? ]x + [ ]

ad-work [718]

Answer:

First box +2

Second box -5

Step-by-step explanation:

Just an Example,

If f(x) = 2x + 1 and we need f(2) we would replace the x in the function with the number 2 because 2 is the domain of the function , so f(2) would become,

f(2) = 2(2) + 1

f(2) = 4 + 1 = 5

Now the question is what is f(g(x)) in this case the domain of the function is g(x). In simpler words we replace x with the function g(x) so here goes,

$f(x)=2x+1\\g(x)=x-3\\f(g(x))=2(x-3)+1\\f(g(x))=2x-6+1\\f(g(x))=2x-5$

so,

f(g(x)) = 2x - 5
