Answer:

$\large\boxed{-3(2+4k)+7(2k-1)=2k-13}$

Step-by-step explanation:

$-3(2+4k)+7(2k-1)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\=(-3)(2)+(-3)(4k)+(7)(2k)+(7)(-1)\\\\=-6-12k+14k-7\qquad\text{combine like terms}\\\\=(-12k+14k)+(-6-7)\\\\=2k-13$

Circle A has radius 4 feet. Circle B has radius 9 feet. What is the ratio of the area of circle A to the area of circle B?

yaroslaw [1]

Answer:

$\large\boxed{\dfrac{16}{81}}$

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

r - radius

Circle A:

radius = 4 ft. Substitute:

$A_A=\pi(4^2)=16\pi\ ft^2$

Circle B:

radius = 9 ft. Substitute:

$A_B=\pi(9^2)=81\pi\ ft^2$

The ratio:

$\dfrac{A_A}{A_B}=\dfrac{16}{81}$

Simply the function f(x)=7(3Square root 54^x)

Pie

Answer:

54 = 2 × 3 × 3 × 3 = 2 × 3³

$f(x) = 7(\sqrt[3]{54})^x$

$f(x) = 7(\sqrt[3]{3^3 \times 2})^x$

$f(x) = 7(3\sqrt[3]{2})^x$

Initial value: x = 0

$f(0) = 7(3\sqrt[3]{2})^0$

$f(0) = 7(1)$

$f(0) = 7$

The initial value is 7.

The domain is all real numbers.

The range is all real numbers greater than zero.
