(-1,-2.5) hope this helps
Answer:
Step-by-step explanation:
1) √2 + 2√2 = ( 1 + 2 ) √2 = 3*√2 = 3√2
4) √8 + √2 = √2*2*2 + √2 = 2√2 + √2 = ( 2 +1 ) √2 = 3√2
7) 2√5 - √5 = (2 - 1)√5 = 1 √5
10 3√5 - 2√5 = (3 - 2) √5 = 1√5
First we write the kinematics equations:
a
v = a * t + vo
r = a * (t ^ 2/2) + vo * t + ro
For Wanda we have: a = 0
v = 5
r = 5 * t
For Dave we have: v = 10
r = 10 * (t-120)
To solve the system of equations, we graph both functions and see where
they intersect.
We have to intersect in the ordered pair:
(t, r) = (240, 1200)
answer If they continue walking at these rates, Dave catch up to Wanda in 240s (1200 ft)
Step-by-step explanation:
<u>The standard form of linear equation:</u>
<u>Convert each equation into standard form:</u>
<h3>#5</h3>
- 3x = 18
- 3x + 0y - 18 = 0
- A = 3, B = 0, C = - 18
<h3>#6</h3>
- y/2 = - 5
- 0x + 1/2y + 5 = 0
- A = 0, B = 1/2, C = 5
