If 12^-x=5, what does 12^2x equal

Mathematics
1 answer:
Amiraneli [1.4K]3 years ago
7 0

Answer:

0.04

Step-by-step explanation:

12^(-x) = 5   (taking log on both sides)

log [ 12^(-x)] = log 5

-x log 12 = log 5

-x = log 5 / log 12

x = - (log 5/log12)

x = -0.6477

12^(2x)

= 12^[2(-0.6477)]

= 12 ^ (-1.295)

= 0.04

Answer:

\sf  \boxed{  \sf y - 3 = \dfrac{3}{2} (x - 6)}

Explanation:

\sf Given \ equation: y = \dfrac{3}{2} x - 5

Comparing it with slope intercept form "y = mx + b" where 'm' is slope and 'b' is y-intercept.

Here slope: 3/2 and y-intercept: -5

Parallel slope has the same tangent slope.

Pass through point (x, y) = (6, 3)

Equation:

\sf y - y_1 = m(x  - x_1)

\rightarrow \sf y - 3 = \dfrac{3}{2} (x - 6)

Answer:

Correct answer:  (x - 10)² + y² = 441 / 4

Step-by-step explanation:

Given:

(a, b) = (10, 0)  the coordinates of the center of the circle

(10, 21/2)  circle passing through this point

The standard form of the circle equation is:

(x - a)² + (y - b)² = r²  where r is radius of the circle

We will replace the given coordinates of the center of the circle and the point it passes through to get the radius of the circle:

(10 - 10)² + (21/2)² = r²  ⇒ r² = (21/2)² = 441 / 4

r² = 441 / 4

(x - 10)² + y² = 441 / 4
