Answer:
Step-by-step explanation:
multiply and divide your equation then subtarct it and you get your answer
Answer:
(b) commutative property
Step-by-step explanation:
The "simplified" expression has the positions of the last two terms in the sum swapped. The property of addition that lets you change the order of the terms is the <em>commutative property of addition</em>.
#1) 4.445 ft
#2) yes
Explanation
#1) The maximum height is the y-coordinate of the vertex. We first find the axis of symmetry, given by x=-b/2a:
x=-0.17/2(-0.005) = -0.17/-0.01 = 17
Plugging this into the equation,
y=-0.005(17²)+0.17(17)+3 = 4.445
#2) Substituting 30 into the equation,
y=-0.005(30²) + 0.17(30) + 3 = 3.6
The ball will 3.6 in the air, so yes, it will clear the 3 ft tall net.
(A) <em>The rate that the point 8,28 represents is;</em> 3.5 cm/s since 28/8 = 3.5
(B) <em>The unit rate is 3.5 cm/s since the rate is constant.</em>
(C) <em>The points lie on the same line and both points results to a rate of 3.5 cm/s.</em>
Well if you were to draw a number line from 0 to 2, 9/10 will be placed right before 1. 10/9 will be placed after one. Wendy jumped the shorter distance.
