Answer:
48cm
Step-by-step explanation:
The perimeter of first shape is 36cm. There are 3 semi circle (curves).
Therefore,
3 curves of semicircle (arc length) = 36
1 curve of semicircle (arc length) = 36/3
= 12cm
In picture 2,
4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)
So,
4×12 = 48cm
Find the equation
alrighty, the slope is rise/run
from (21,-3) to (28,-1)
rise is from -3 to -1 or a rise of 2
run is form 21 to 28 or a run of 7
so slope is 2/7
y=2/7x+b
find b which is the y intercept
alirhgty
use (21,-3)
x=21 and y=-3
-3=(2/7)(21)+b
-3=42/7+b
-3=6+b
-9=b
y=2/7x-9
the y intercept is (0,-9
the x intercept is where y=0
0=2/7x-9
9=2/7x
63/2=x
x intercept is (63/2,0) or (31.5,0)
y intercept is (0,-9)
25 because -50 is negative
Answer:
would that be 31 if if im wrong im just nine Step-by-step explanation:
The remainder when the polynomial f(x) = 3x³ - 4x² + 2x + 8 is divided by (x - 5) is constant an equal f(5).
Substitute x = 5 to the polynomial:
Answer: (3x³ - 4x² + 2x + 8) : (x - 5) = q(x) + 293.
