Answer:
x = 748 inches
Step-by-step explanation:
.0254 meters in 1 inch
set up a proportion:
.0254/1 = 19/x
cross-multiply:
.0254x = 19
x = 19/.0254
x = 748.03
44/9 = 4 remainder 8
so as a mixed number it is 4 and 8/9
Answer: (i think there was supposed to be a photo attached but ???)
-1.05
Step-by-step explanation:
1.5(-3.2 + 2.5)
1.5 x -3.2 = -4.8
1.5 x 2.5 = 3.75
(-4.8 + 3.75)
<u>-1.05</u>
2. find y'' of y = x(x+2)
y=x²+2x
y'=2x+2
3. find y'' of y = (3x+1)(x-2)
y=3x²+x-6x-2
y=3x²-5x-2
y'=6x-5
4. find y'' of y = (3x+4)squared
y=(3x+4)²
y'=2(3x+4)(3)=6(3x+4)=18x+24
5. find y' of y = 3x-2
y'=3
