H=height of ostrich
k=height of kiwi
h is 20 more than 4 times k
k=20+4k
k=108
108=20+4k
minus 20 from both sides
88=4k
divide both sides by 4
22=k
answer is A
Which set of ordered pairs represents a function? answer choices {(2, 1), (5, 3), (6, 4), (1, 4)} {(5, 12), (7, 34), (9, 3), (9,
dexar [7]
The first set of the ordered pair is the answer
Answer:
.5 < x < 16.5
Step-by-step explanation:
The smallest x can be is greater than the difference of the other two sides
8.5 -8 = .5
The largest x can be the less than the sum of the two sides
8.5+8 = 16.5
.5 < x < 16.5
Answer:
18
Step-by-step explanation:
7 - 5 = 2
triangle = bh/2
triangle = 2(3) / 2
triangle = 3
rect = bh
rect = 3 x 5
rect = 15
trapezoid = 15 + 3
trapezoid = 18
Answer:
Step-by-step explanation:
we know that
The height of Justin’s rocket is modeled by the equation
This is the equation of a vertical parabola open downward
The vertex is a maximum
where
The coefficient of t^2 represent the acceleration
The coefficient of t represent the initial velocity
The constant of the equation represent the initial height
Remember that
Elena launched his rocket from the same position, but with an initial velocity double that of Justin’s
so
Now the initial velocity is
substitute
The height of Elena’s rocket is the equation
