Answer:
I believe the slope is m = 0.
(Let me know if you need the work)
Answer:
1. 17.584 feet
2. 81.64 mm
3. 9
4. 12
Step-by-step explanation:
The formula for the circumference of a circle is 2 times pi (or 3.14 in your case) times the radius of the circle.
1. Using the above formula, we can plug in the radius:
2*3.14*2.8 = 17.584
2. This is similar to the above question, so we plug in the radius into the formula:
2*3.14*13 = 81.64
3. We know the circumference of the circle so we can plug it in the formula:
56.5 = 2*3.14*r
56.5 = 6.28*r
r = 8.996 (roughly 9)
4. This is similar to question 3 so we do the same thing:
75.4 = 2*3.14*r
75.4 = 6.28*r
r = 12
To use substitution, you find the part of the first equation that is equal to x, and substitute it for x into the second equation, then you can solve for y as it is the only variable. In the first equation x is equal to 8-3y. If we substitute this into the second equation we get 2(8-3y)-y=2. We then multiply this out to get 16-6y-y=2, or 16-7y=2.
Answer:
∛27 = 3
Step-by-step explanation:
A radical is simply a fractional exponent:
Hence, ∛27 =
Since 27 = 3³, then:
You could rewrite ∛27 as ∛(3)³.
Multiplying the fractional exponents (3 × 1/3) will result in 1 (because 3 is the <u><em>multiplicative inverse</em></u> of 1/3). The multiplicative inverse of a number is defined as a number which when multiplied by the original number gives the product as 1.
Therefore, ∛27 = 3.
