Answer:
C: -|x| + 3
Step-by-step explanation:
From the graph, we see that when y = 2, x is either +1 or -1
Also,when y = 1, x = +2 or -2
Thus,we can say that;
y = (-x) + 3 or -(x - 3)
So, we can write this in absolute value form as; y = -|x| + 3
Your original perimeter is 32cm. 3/2 is equal to 1.5. 32x1.5= 48 cm perimeter
Complete question :
Lucy has block letters that are in the shape of cubes with sides 2 3 foot long. She has a box which is 1 1 3 foot long, 2 3 foot wide, and 2 3 foot tall. Find the number of block letters that will fit in the box.
Answer:
1/2
Step-by-step explanation:
Number of block letters that will fit in :
Volume of box ÷ volume of each letter cube
Volume of each letter cube = (side length)³ = (2/3)³ = 8/27 ft³
Volume of box = length * width * height
Volume of box = 1 1/3 * 2/3 * 2/3
Volume of box = 4/3 * 2/3 * 2/3 = 16 / 27 ft³
Therefore ;
8/27 ÷ 16/27
8/27 * 27/16
= 8/16
= 1/2
(side note: your formula C = 2πr^2 is incorrect, it should be C = 2πr)
Answer:
r = 9
Step-by-step explanation:
First let's find the circumference of Circle A. To use the formula we need radius. Since we have a diameter just divide by 2 to get radius. 27 / 2 = 13.5
Now plug that into C = 2πr: 2π*(13.5) = 27π
The question says that the area of circle B is 3x this value, so Circle B's area must be: 27π * 3 = 81π
Now plug that into A = πr^2 and solve for r:

U should add all the #s together so... it = 11.3
then divide by the # of terms. so...... 11.3/ 14= 0.9357 (rounded makes 0.94)
So .... B
