Find two values for k such that the trinomial x2 – 7x + k can be factored over the integers. Explain your reasoning.
vova2212 [387]

Answer:

1) For a = 1: b = 6 and k = 6, 2) For a = 3: b = 4 and k = 12

Step-by-step explanation:

The polynomial y = x^{2} - 7\cdot x + k is a second-order polynomial of the form (x-a)\cdot (x-b) = x^{2}-(a+b)\cdot x + a\cdot b. By direct comparison, we construct the following system of equations:

a + b = 7 (1)

a\cdot b = k (2)

By (1) we know that there are a family of pairs such that the system of equations is satisfied. Let suppose that both a and b are integers. We assume two arbitrary integers for a:

1) a = 1

b = 7 - a

b = 6

a\cdot b = k

k = (6)\cdot (1)

k = 6

2) a = 3

b = 7 - a

b = 4

a\cdot b = k

k = (3)\cdot (4)

k = 12

Which set of side lengths form a right triangle?
astraxan [27]
Since we don't want to use the Pythagorean Theorem on all of these, first we look for some Pythagorean Triples. Its very helpful to know some of the common ones, so here's a list:

3, 4, 5
5, 12, 13
7, 24, 25
8, 15, 17

So we either look for these or a multiple of these numbers.

The last one is the only one that fits because 15, 20, 25 is a multiple of the triple 3, 4, 5 by multiplying all of them by 5. 

Thus, 15, 20, 25 forms a right triangle.

Zhang is designing protective packaging. He tests his design by dropping a raw egg protected by his packaging from various heigh
Softa [21]

Answer: 12.034 yards

Step-by-step explanation:

Given the following :

Height to which egg is protected = 11 meters

Converting this height of 11 meters to yards

Let the height in yards = h

1 meter = 1.094 yards

11 meters = h

(1 * h) = (11 * 1.094)

h = 12.034 yards

Hence, the height in yards to which egg is protected = 12.034 yards
