Believe it or not, I think the answer is 640. Not 100% sure though. Good luck!
Answer:
75
Step-by-step explanation:
So we have:
Take the derivative of the function. Use the power rule, which states that:
Therefore:
Use power rule:
Now, substitute in -5:
Square and multiply:
So our answer is 75.
This means that the slope of the line tangent to the point (-5,-125) on the graph x^3 is 75.
And we're done!
Answer:
x= 6.25
Step-by-step explanation:
The hypotenuse of triangle JKL is taken as 96, in the similar way the hypotenuse of triangle JTU is 36. So x can be found by first finding the value of JU, using the Pythagoras theorem.
In this shape the formula will be:
Substitute the given values in the shape into the formula.
TU = 34
JT = 27
TU = Lets take 'y'
1156 = 729 +
= 1156 - 729
= 427
y = = 20.7 ( rounded to 1 decimal place) = 21 (rounded to whole number).
So the original value of JU is '21', but we have to find the value of 'x'. So the expression '-4 + 4x' is equal to 21. This can be written as:
-4 + 4x = 21
4x = 21 + 4
4x = 25
∴ x = = 6.25
x= 6.25
