Answer:
^7√(-4)^2 or 1.48 I hope it helps
2.)
average velocity=(change in distance)/(change in time), in this case:
v=(549 9/10)/(7 50/60)
v=(5499/10)/(470/60)
v=(5499/10)(60/470)
v=32994/470
v=70.2 km/hr

Make two position functions...
c=15t, and r=120-20(t-1)
c=15t, r=140-20t
They meet when c=r so:
15t=140-20t add 20t to both sides
35t=140 divide both sides by 35
t=4
So they will meet 4 hours after Cindy leaves at 1 pm, thus they meet each other at 5 pm.
check...
c=15(4)=60
r=120-20(4-1)
r=120-20(3)
r=60
Answer:
3/1
Step-by-step explanation:
Using the similarity statement, ∠A corresponds with ∠D; ∠B corresponds with ∠E; and ∠C corresponds with ∠F.
The only angle of triangle DEF we have is ∠E, which is 7. This corresponds with ∠B; this makes the scale factor of ABC to DEF
21/7 = 3/1.
Volume of a cube is expressed using
V= a^3
I can’t really see what the volume says in the picture, if the number there says 3
x wouldn’t be 3 because the volume is already given
It would be
a^3= 3
a= 3√3
Slope = (1 - 2)/(0 -(-2) = -1/2
Answer
-1/2
