Answer:

10 cm

Step-by-step explanation:

1 decimeter is equal to 10⁻¹ meters.

1 meter is equal to 10² centimeters. We can use a conversion fraction to find the centimeters corresponding to 10⁻¹ meters.

10⁻¹ m × (10²cm/1 m) = 10 cm

1 dm = 10⁻¹ m

10⁻¹ m = 10 cm

Due to the transitive property, 1 decimeter is equal to 10 centimeters.

f(x) = 2^(4x)

g(x) = 2^x

(fg) = 2^4x * 2^x = 2^5x

NOTE: When multiplying two powers with same base exponents add.

(f/g)(x) = (2^4x)/(2^x) = 2^3x

NOTE: And when dividing they subtract.

Answer: a and c

Write an equation of a parabola that passes through (3,-30) and has x-intercepts of -2 and 18. Then find the average rate of cha

Nookie1986 [14]

Answer:

The equation of the parabola is $y = \frac{2}{5}\cdot x^{2}-\frac{32}{5}\cdot x -\frac{72}{5}$ . The average rate of change of the parabola is -4.

Step-by-step explanation:

We must remember that a parabola is represented by a quadratic function, which can be formed by knowing three different points. A quadratic function is standard form is represented by:

$y = a\cdot x^{2}+b\cdot x + c$

Where:

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

$a$ , $b$ , $c$ - Coefficients, dimensionless.

If we know that $(3, -30)$ , $(-2, 0)$ and $(18, 0)$ are part of the parabola, the following linear system of equations is formed:

$9\cdot a +3\cdot b + c = -30$

$4\cdot a -2\cdot b +c = 0$

$324\cdot a +18\cdot b + c = 0$

This system can be solved both by algebraic means (substitution, elimination, equalization, determinant) and by numerical methods. The solution of the linear system is:

$a = \frac{2}{5}$ , $b = -\frac{32}{5}$ , $c = -\frac{72}{5}$ .
