Answer:
A) 684 in^2
Step-by-step explanation:
Since it needs to be painted all around the box we have to find the surface area of the box
The surface area of cuboid is
=2lw+2lh+2hw (l: length, w: width, h: height)
=2×15×12+2×6×15+2×6×12
= 684 in^2
Answer:
73.2km
Step-by-step explanation:
first you have to decompose 46 km into y and x components.
x=sin40°*46km
x=0.64*46km
x=29.44km
y=cos40°*46km
y=0.76*46km
y=34.96
now you add the y components together
32+34.96=66.98
finally use Pythagorean thereom to find the resultant vector.
a*a+ b*b=c*c
66.98*66.98+29.44*29.44=c*c
c*c= 4486.3+866.7
c=√5353
c=73.2 km this is the approximate value
Answer:
y = 3/8x +29/8
Step-by-step explanation:
First we need to find the slope
m= (y2-y1)/(x2-x1)
= (1-4)/(-7-1)
= -3 /-8
= 3/8
Then we can use the slope intercept form of the equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 3/8x +b
Substitute a point into the equation to find b
4 = 3/8(1) +b
Subtract 3/8 from each side
32/8 -3/8 = 3/8-3/8+b
29/8 = b
Substitute b back into the equation
y = 3/8x +29/8
Answer:
4/3
Step-by-step explanation:
3y=4x-12
divide by 3 to isolate y
y=4/3x-4
slope is 4/3
