Answer:
x>5
Step-by-step explanation:
Okay so john ran the diameter on the park
emily ran the circumference
πd = the circumference
therefore emily ran further
Answer:
<h2>a) x = 16 and y = 6</h2><h2>b) P = 864 in</h2>
Step-by-step explanation:
a)
The opposite sides of the rectangle are of equal length.
Therefore we have the system of equations:
Substitute from (*) to (**):
Put the value of y to (*):
b)
Calculate the width and the length:
The perimeter:
The solution to your problem is as follows:
The tangent line passes through (4,-6), so x = 4 when y = -6
=> f(4) = -6
The tangent line will have a constant gradient.
gradient is m = (-6 - 9)/(4 - 10) => 5/2
Equation is y - 9 = (5/2)(x - 10)
=> y - 9 = (5/2)(x-10)
<span>i.e. y = (5/2)(x-10) + 9
</span> y = (5/2)x - 25 + 9 = y = (5/2)x - 16
Now, f '(x) = dy/dx = 5/2
so, f '(4) = 5/2....i.e. gradient is 5/2 whatever the value of x.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
Its kinda the same as the A just in the negative
