It is linear as the equation performs ax+by +c
y = 90.2x - 177670
number of student to enroll 2011 is 3722

Step-by-step explanation:

Linear is a straight line.
Quadratic is a square which generates parabola.
Quadratic formula is (ax)^2 + bx + c = 0.
Linear formula is ax+bx + c = 0
To forecast time series data modelling can be used.
To form a linear equation y = mx + c.
After finding x is the required value , m is the intercept and C constant.
X axis have years and Y axis has the value.
to find number of students x is 90.2 * 2011 - 177670.
The result comes to 3722.
In Data analysis predictive modeling is the second phase.
It is important because it helps in associating to variables.

Answer:

-22+27i

Step-by-step explanation:

$i = \sqrt{ - 1} \\ (3 - 4i)( - 6 + i) \\ = (3 - 4 \sqrt{ - 1} )( - 6 + \sqrt{ - 1} ) \\ = 3( - 6 + \sqrt{ - 1)} - 4 \sqrt{ - 1} ( - 6 + \sqrt{ - 1} ) \\ = - 18 + 3 \sqrt{ - 1} + 24 \sqrt{ - 1} - 4 \\ = - 22 + 27 \sqrt{ - 1} \\ putting \: \: \: \sqrt{ - 1 } = i \\ = - 22 + 27i$

Hope it helps.

a_sh-v [17]

Answer:

52/ 10 = 5 2/10 or 5 1/5

Step-by-step explanation:

first turn the mixed fractions into improper fraction

13 1/10= 131/10

7 9/10= 79/10

since the two fractions already have a common denominator just subtract

131 - 79 = 52

52/ 10 = 5 2/10 or 5 1/5

The total amount of spending per year, in billions, on pets in a certain country x years after 2000 is given by the following

Kamila [148]

Answer:

40.4502 billion dollars

51.3432 billion dollars

Step-by-step explanation:

Given :

Total amount spent in billions in pets x years after year, 2000 ;

P(x)=2.1786x + 25.2

Amount spent in 2007 ;

x = 2007 - 2000 = 7 years

Put x = 7 in the equation :

P(7)=2.1786(7) + 25.2 = 40.4502

Amount spent in 2012 :

x = 2012 - 2000 = 12 years

Put x = 12 in the equation :

P(12) = 2.1786(12) + 25.2 = 51.3432

The amount spent in billik dollars on pets in :

2007 = $404502 billion

2012 = $51.3432 billion
