Answer:

$357.42

Step-by-step explanation:

So first I multiplied $425.50 by 20%.

$425.50 * 0.20=  85.10

$425.50- 85.10= $340.40

$340.40 * 0.05 = $17.02

$340.40 * 0.07 = $23.828

$340.40 + 23.828 + 17.02= $ 357.42

The sale price of Dean's guitar is $357.42.

Answer:

The output is 23

Step-by-step explanation:

we know that

f(x) ----> is the output

x ----> is the input

we have that

f(x)=3x-1

For x=8 (input)

Find the value of f(x) (output)

f(8)=3(8)-1=23

The output is 23

The x intercepts of a parabola are (6,0) and (-2,0) determine the x coordinate of the vertex
lubasha [3.4K]
This means that (x-6)(x+2) = f(x) is the equation for the parabola due to that if you plug these in, when x=6 and x=-2 then y=0. Expanding it, we get
x^2+2x-6x-12=x^2-4x-12. Since the x coordinate of the vertex is -b/2a, it's 4/2=2

Expand: In 2a^3/b^4
Ket [755]

Answer:

  ln(2) +3ln(a) -4ln(b)

Step-by-step explanation:

  \ln{\left(\dfrac{2a^3}{b^4}\right)}=\ln{(2a^3b^{-4})}=\ln{(2)}+\ln{(a^3)}+\ln{(b^{-4})}\\\\=\boxed{\ln{(2)}+3\ln{(a)}-4\ln{(b)}}

__

The applicable rules of logarithms are ...

  log(ab) = log(a)+log(b)

  log(a^b) = b·log(a)

The length of a rectangular prism is 4 more than 3 times the width, w. The volume of the prism is 3w^3 + 16w^2 + 16w. What is a
Fiesta28 [93]

Answer:

Height = w + 4

Step-by-step explanation:

3w³ + 16w² + 16w = w (3w² + 16w + 16)

= w (3w + 4) (w + 4)

The length of a rectangular prism is 4 more than 3 times the width, w

L = 3w + 4

R prism volume = L x W x H

Height = w + 4
