Which of the following exponential functions goes through the points (1, 12) and (2, 36)?

Savatey [412]

Answer:

The function through which given point passes is f(x) = 24 x - 12 .

Step-by-step explanation:

Given as :

The points are

$x_1$ , $y_1$ = 1 , 12

$x_2$ , $y_2$ = 2 , 36

now, slope of the line

Let The slope of line = m = $\frac{y_2-y_1}{x_2-x_1}$

Or, m = $\frac{36 - 12}{2-1}$

Or, m = 24

So The slope of line = m = 24

Now, equation of line in point-slope form

y - $y_1$ = m × (x - $x_1$ )

Or, y - 12 = 24 × (x - 1 )

or, y - 12 = 24 x - 24

or, y = 24 x - 24 + 12

or, y = 24 x - 12

or , f(x) = 24 x - 12

So, The function through which given point passes is f(x) = 24 x - 12 . Answer

Help with trigonometry

diamong [38]

Answer:

cos ∠CBD = - 4√41 / 41

Step-by-step explanation:

AB = 4 ΔABC = (4 x AC) / 2 = 10

AC = 5

BC = √5² + 4² = √41

cos ∠CBD = cos (180° - ∠CBA) = cos 180° cos ∠CBA + sin 180° sin ∠CBA

(cos 180° = - 1 sin 180° = 0 cos ∠CBA = 4 / √41 )

cos ∠CBD = (-1) x cos ∠CBA = - 4 / √41 = - 4√41 / 41

Given f(x) = x+2 and g(x) = x-4 solve for (fg)(x)

kirza4 [7]

Answer: f(g(x)) = x - 2

Step-by-step explanation:

f(x) = x + 2

g(x) = x - 4

f(g(x)) = f(x - 4) = (x - 4) + 2 replaced x with x - 4

= x - 2 simplified
