Answer:
1.) f(x) = x*x - 7x + 10
2.) f(x) = x*x - 5x
3.) f(x) = 4*x*x - 5x - 6
4.) f(x) = 6*x*x -5x + 1
Step-by-step explanation:
1.) 2 and 5 (x -2)(x - 5) = f(x) = x*x - 7x + 10
2.) 0 and 5 f(x) = x*(x -5) = x*x - 5x
3.) -3/4 and 2 (x + 3/4)(x -2) = x*x - (5/4) x - 3/2,
need integers f(x) = 4xx - 5x - 6
4.) 1/2 and 1/3 (x - 1/2)(x - 1/3) = f(x)
x*x - 1/3 x - 1/2 x + 1/6
xx - 5/6 x + 1/6
6 xx - 5x + 1
The volumes of spheres are proportional to R³. So their 'R's
are proportional to ∛their volumes.
(729/ 27) = 27
∛27 = <u>exactly 3</u> . No rounding required.
Answer:
The required equation is : 5 · 4000 = 20,000
Step-by-step explanation:
We have to use multiple of 10 for at least one factor.
So, in order to form our equation, we take one factor as 4000 which is a multiple of 10 (10 × 400 = 4000)
And the other condition to form the equation is given that the product should contain 4 zeros, so we need to multiply the first factor 4000 by some number such that the product contains 4 zeros.
Therefore, if we multiply 4000 by 5 we get the product as 20000 which contains 4 zeros.
Hence, 5 × 4000 = 20,000 is our required equation.
Answer: 300, the volume is 300 because you take 10 times 5 times 6 and you get the volume
