8.3 is your answer. Hope I helped :)
Answer:
12
Step-by-step explanation:
48 times 2/3 gives you the amount of runners that dropped out in the first half of the race. take that number (32), and subtract it from the original. You should be left with 16. Then take 1/4 of the remaining runners (16 times 1/4, which is 4), and subtract it from 16. this gives you 12
Answer: A
48+ 36 = 84
84/4 = 21 groups
there are 21 groups of 4 balloons
Answer:
Step-by-step explanation:
Given that:
At point (5,3)
To find an equation of the tangent to the curve at the given point,
By without eliminating the parameter
t² + 5 = 4
t² = 4 - 5
t² = - 1
Then;
The equation of the tangent is:
y - 3 = -2x +10
y = -2x + 7
y = 2x - 7
By eliminating the parameter
x = 5 + In(t)
In(t) = 5 - x
The equation of the tangent is:
y - 3 = -2x +10
y = -2x + 7
y = 2x - 7
