Estimate 40% of 20 equals

2 answers:

7 0

40% of 20 equals 8.

First, we need to think that 20 is our 100%.
Let's make the variable v as the value we're looking for.

20/v = 100/40
We need to multiply both sides of the equation by v.
(20/v) * v = (100/40) * v

Now, we're left with 20 = 2.5x

We need to divide both sides of the equation to isolate the variable x.
20/2.5 = 2.5x/2.5
8 = x

Our final answer is 8.

Suppose that we don't have a formula for g(x) but we know that g(3) = −1 and g'(x) = x2 + 7 for all x.

Sliva [168]

Answer:

g(2.95) ≈ -1.8; g(3.05) ≈ -0.2
A) tangents are increasing in slope, so the tangent is below the curve, and estimates are too small.

Step-by-step explanation:

(a) The linear approximation of g(x) at x=b will be ...

g(x) ≈ g'(b)(x -b) +g(b)

Using the given relations, this is ...

g'(3) = 3² +7 = 16

g(x) ≈ 16(x -3) -1

Then the points of interest are ...

g(2.95) ≈ 16(2.95 -3) -1 = -1.8

g(3.05) ≈ 16(3.05 -3) -1 = -0.2

(b) At x=3, the slope of the curve is increasing, so the tangent lies below the curve. The estimates are too small. (Matches description A.)

Three students need to produce a prime factorization of 48. Donna states that the first factors in the tree should be 6 and 8. L

Gennadij [26K]

If we start with 6 and 8, we can break 6 up into 2*3 and 8 into 2*2*2, thus getting a prime factorization of 2*2*2*2*3, or 2^4 *3.

If we begin with 4 and 12, 4 breaks into 2*2 and 12 into 2*2*3, so the prime factorization of 48 is still 2^4 *3.

The starting factors do not matter, since the answer comes out to be the same. There is exactly one correct answer- it doesn't matter how it's found.

Hope this helps! :)
