Multiplying a fraction by a repeating decimal since a fraction is rational and a repeating decimal is rational (repeating numbers will always be rational). Rational number time rational number=rational Pi is an irrational number since the numbers are not repeating (3.1415926535 no repeating numbers as opposed to 0.3333333333333333333 or 0.1919191919)
Answer:
The product
Step-by-step explanation:
Given expression and
We have to find the product of
Consider the given expression
Multiply fractions, we have,
Cancel common factor ( b - 5 )
we have,
Apply exponent rule,
Cancel common factor b , we have,
Thus, the product
Answer:
9π, or 28.26
Step-by-step explanation:
The Arc of the semicircle is the circumference of half a circle.
The radius of the semicircle is 9, and the circumference of a circle is 2πr, so it is 2π9 = 18π. since this is a semicircle, it is half of that, so 9π, or 28.26, since π is 3.14 here
Answer:
25x-10y-30
Step-by-step explanation:
5(5x - 2y - 6)=(5*5x)(-5*2y)(-5*6)=25x-10y-30
Use the slope formula below:
To form an equation of a line - we need to find a slope and the y-intercept from y = mx+b. We are given two points which we can substitute in the formula.
We have finally got the slope. Next is to find the y-intercept. First we rewrite the equation of y = mx+b by substituting the slope.
The equation above is the slope-intercept form. Substitute m = -7/6 in the equation.
Since the graph passes through (0,0) which is an origin point. In y = mx+b if the graph passes through origin point, that means the b-value is 0. Therefore:
