Answer:
yes, they are parallel lines in #23
Step-by-step explanation:
the slope of both lines is -1
S.A = (2×area of base) + area of lateral faces
Area of lateral faces = area of base × height
Area of lateral faces = 19×4×8=608
S.A = (2×19×4)+608
=760
Answer:
t=5
Step-by-step explanation:
∵ (t,17) lies on (x,y) plane y=x²-3x+7,t>0
∴ 17=t²-3t+7
t²-3t+7-17=0
t²-3t-10=0
t²-5t+2t-10=0
t(t-5)+2(t-5)=0
(t-5)(t+2)=0
t=5,-2
t>0
so t=5
Answer:
-2x-10
Step-by-step explanation:
just distribute the -2 :)
We find the value for s here.
8s = 1/2
1/2 divided by 8/1 = 1/2 * 1/8 = 1/16
s = 1/16
