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.

Y=2/3x-2
to find intercepts, substitute 0 into y and solve for x = x intercept is (3,0) and repeat for y. substitute 0 into x to get y intercept of (0,-2)

Situation:

FromTheMoon [43]

Answer:

5.6 days

Step-by-step explanation:

We are given;

Initial Mass; N_o = 25 g

Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)

k = 0.1229

Formula is given as;

N_t = N_o•e^(-kt)

Plugging in the relevant values;

12.5 = 25 × e^(-0.1229t)

e^(-0.1229t) = 12.5/25

e^(-0.1229t) = 0.5

(-0.1229t) = In 0.5

-0.1229t = -0.6931

t = -0.6931/-0.1229

t = 5.6 days

Choices;<br> a) 21.8°<br> b) 35.2°<br> c) 45.1°

kifflom [539]

Answer:

$\displaystyle a) \: {x}^{ \circ} = 21.8 ^{ \circ}$

Step-by-step explanation:

we are given opposite and adjacent

we want to figure out x°

remember that,

$\displaystyle \: \tan( \theta) = \frac{opp}{adj}$

where our opp is 5 and adj is 12.5

let $\theta$ be x°

$\displaystyle \: \tan( {x}^{ \circ} ) = \frac{5}{12.5}$

$\displaystyle \: {x}^{ \circ} = \arctan \left( \frac{5}{12.5} \right)$

by using calculator

$\displaystyle \: {x}^{ \circ} = 21.8$

hence,

our answer is a
