Answer:

When effective length (L) is constant, the time period (T) of oscillation of a simple pendulum is inversely proportional to the square root of the acceleration due to gravity (g) at a place of observation. So, T∝√1g when L is constant.

Answer:

k=-2

Step-by-step explanation:

Let's write the left hand side as a negative power, and 9 as a power of 3:

3^-^k=3^2 At this point, for the equality to still stand, the exponents have to be equal:

-k = 2 \rightarrow k=-2

HELP!! PLEASE A carpenter is framing a window with wood trim where the length of the window is 9 and 1/3 feet. If the width of t
ohaa [14]
We need the perimeter of the window for framing

The window is in the shape of a rectangle with the height of 9 \frac{1}{3} feet and width of 6 \frac{3}{4}. The diagram of the shape is shown below

The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.

The perimeter of the window is 9 \frac{1}{3}+9 \frac{1}{3}+6 \frac{3}{4}+6 \frac{3}{4} = 18 \frac{2}{3}+12 \frac{6}{4} 

We have two whole numbers 18 and 12 and two fractions \frac{2}{3} and \frac{6}{4}

Adding the two fractions that have different denominator 
\frac{2}{3}+ \frac{6}{4} = \frac{8}{12}+ \frac{18}{12}= \frac{26}{12}, which is an improper fraction which we can change into a mixed number 2 \frac{1}{6}

So the perimeter of the window is 
18+12+2 \frac{1}{6} =32 \frac{1}{6} 

and the length of wood needed for the frame is 32 \frac{1}{6} feet

HELP! ANYONE!?! BRAINLEST ANSWER OFFERED!!
leva [86]

Answer:

y = - 1/3 +2

Step-by-step explanation:

✯Hello✯

↪  first we need to rearrange this so the answer is equal to Y

↪  -3x on both sides

↪  9y =-3x+18

↪  then divide by 9 to get y on its own

↪  Then we can simplify the answer -3x+18/9 further so the 2nd option is the answer
