Answers

Answer 1

Answer:

We now want to ﬁnd the best approximation to a given function. This fundamental problem in Approximation Theory can be stated in very general terms. Let V be a Normed Linear Space and W a ﬁnite-dimensional subspace of V , then for a given v ∈ V , ﬁnd w∗∈ W such that kv −w∗k ≤ kv −wk, for all w ∈ W.

I can confirm the answer is B but another person already answered it so I might not take all the credit

Solve for b pls. Due by 2:45.....

Answers

Answer:

b = 12

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

b² + 5² = 13²

b² + 25 = 169 ( subtract 25 from both sides )

b² = 144 ( take the square root of both sides )

b = [tex]\sqrt{144}[/tex] = 12

4.5 > 4.420

0.67 < 0.8

0.82 = 0.820

62.4 > 6.24

0.13, 0.3, 0.303, 0.32

0.08, 0.8, 0.82, 8.2

24.54, 24.4, 24.304, 24.24

6.5, 6.25, 6.05, 6.007

Step-by-step explanation:

The most useful way to compare fractions is to add extra zeros at the end.

For example, 0.67 ___ 0.80.

0.80 is obviously bigger than 0.67.

In 24.4, 24.54, 24.304, 24.24, you can add extra zeros as well.

24.400, 24.540, 24.304, 24.240 (This makes it much easier to group the numbers, whether from largest to smallest or smallest to larger).

3 numbers are in arithmetic progression their sum is15 and their product is 80 determine the 3 numbers

Answers

Answer:

2, 5, 8

Step-by-step explanation:

For starters, let us assume that the numbers are x-d, x, and x+d.

Where d is the common difference between terms.

This mean that we can say, from the question

x-d + x + x+d = 15

3x = 15,

x = 5,

This means that the terms are 5, 5-d and 5+d.

On the other hand,

(5-d) * 5 * (5+d) = 80

(5-d) * (5+d) = 80/5

(5-d) * (5+d) = 16

25 - d² = 16

d² = 9

d = + or - 3.

Finally, the three numbers will be 2, 5, and 8. On the flipside, their sum and product are 15 and 80.
