Step-by-step explanation:
Answer:
<h3>The answer is 157.08 mm</h3>
Step-by-step explanation:
Circumference of a circle = πd
where
d is the diameter of the circle
From the question
d = 50 mm
The circumference of the circle is
C = 50π
= 157.07963267949…
We have the final answer as
<h3>157.08 mm</h3>

Answer: x+4 = 12
Step-by-step explanation:
y = 7x - 3
Note the gradient of the tangent is the derivative of y at x = 1
Differentiate using the power rule
(a
) = na
y = 3x³ - x² + 2
= 9x² - 2x
x = 1 : = 9 - 2 = 7 ← gradient of tangent
equation in point- slope form, using m = 7 and (a, b) = (1, 4)
y - 4 = 7(x - 1) ← point-slope form
y - 4 = 7x - 7
y = 7x - 3 ← in slope-intercept form
The absolute value of any number will always be a positive number. That is the definition of an absolute value. It is usually denoted by the || bar. For example, when you want to find the sum of 1 and ⁻5, you write it as |1 + ⁻5|. Even though the actual answer is ⁻4, because it is in absolute value, you'll report it as +4 instead.
