Answer:
5D-2
Step-by-step explanation:
5 times d = 5d. subtract 2 is after the 5d
Answer:
measure of supplementary angle 180-69.3=110.7
To find the gradient of the tangent, we must first differentiate the function.
The gradient at x = 0 is given by evaluating f'(0).
The derivative of the function at this point is negative, which tells us <em>the function is decreasing at that point</em>.
The tangent to the line is a straight line, so we will have a linear equation of the form y = mx + c. We know the gradient, m, is equal to -1, so
Now we need to substitute a point on the tangent into this equation to find c. We know a point when x = 0 lies on here. To find the y-coordinate of this point we need to evaluate f(0).
So the point (0, -1) lies on the tangent. Substituting into the tangent equation:
Answer:
Step-by-step explanation:
2. 24^2+7^2 = 625
V 625 = 25
3. 6^2 + 5^2 = 25 +36 = 61
V 61 =7.81024967 =7.8
4. 4^2 +9^2 = 97
V 97= 9.84885780 = 9.8
5. 2^2 +3^2 = 13
V 13 =3.60555127 =3.6
and done!
