First you multiply 2and3/8 by 4 and which you will get 3 then you subtract 23 and 3 and get 20
Answer:
Step-by-step explanation:
we need to find the equation of the parabola with vertex (-5,3), with axis parallel to the x-axis.
general equation of horizontal parabola is
where (h,k) is the vertex
(-5,3) is the vertex. h=-5 and k=3. plug in the values in the general equation
Now find out the value of 'a' using x intercept (4,0)
Add 5 on both sides
a=1
the equation becomes
Answer:
<h2>158,400 m. or 158.4 km.</h2>
Step-by-step explanation:
<u>distance = velocity x time</u>
where: time = 2 hrs. x 3600 sec / 1 hr
= 7200 secs
velocity = 22 m/s
plugin values into the formula:
distance = 22 m/s x 7200 sec.
= 158,400 m. or 158.4 km
Checking answer A:
distance from U to V = -2-(-11)=9
distance from U to W =7-(-2)=9 -> same distance !
checking answer B:
distance U-V : -2-(-8)=6
U-W : -2-(-6)=4 -> not the same distance
answer C :
U-V : -2-(-6)=4
U-W : 6-(-2)=8 -> not the same distance
answer D :
U-V : 0-(-2)=2
U-W : 2-(-2)=4 -> not the same distance
Conclusion : answer A
