Factor as a product of two binomials x2-x-72

Natasha_Volkova [10]

Answer:

(x - 9)(x + 8)

Step-by-step explanation:

Given

x² - x - 72

Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 1)

the factors are - 9 and + 8, since

- 9 × 8 = - 72 and - 9 + 8 = - 1, thus

x² - x - 72 = (x - 9)(x + 8)

Answer:

Option A Center (5,-4) radius 7

Step-by-step explanation:

x^2 +y^2 - 10x +8y - 8= 0

Center(-g,-f)

2gx = - 10x

g = - 5

2fy = 8y

f = 4

Center (5,-4)

Radius = square root of (g^2+f^2 - c)

r = square root of (5^2 + - 4^2 - (-8))

r = square root of (25+16+8)

r = square root of 49

r = 7

Among fatal plane crashes that occurred during the past 55 years, 415 were due to pilot error, 96 were due to other human err

azamat

Answer:

Relative frequency:

$\text{Pilot error}=415/1370=0.30\\\\\text{Other human error}=96/1370=0.07\\\\\text{Weather}=169/1370=0.12\\\\\text{Mechanical problems}=622/1370=0.45\\\\\text{Sabotage}=68/1370=0.05\\\\$

The most serious threat to aviation safety is, according to this data, "mechanical failures". It can be improved by more rigorous inspection and better maintenance policies and execution.

Step-by-step explanation:

We have the data for fatal plane crashes. The sum of plane crashes is

We can calculate the relative frequency as:

$\text{Pilot error}=415/1370=0.30\\\\\text{Other human error}=96/1370=0.07\\\\\text{Weather}=169/1370=0.12\\\\\text{Mechanical problems}=622/1370=0.45\\\\\text{Sabotage}=68/1370=0.05\\\\$

We can see that the most frequent cause is "mechanical problems", with a relative frequency of 0.45.
