Answers

Answer 1

Answer:

madision be $12

Jasmine be $24

And, the devanie be $18

Step-by-step explanation:

The computation is shown below:

Madison be x

Jasmine be 2x

Devanie be x + 6

And, the total is $54

Now the equation is

x + 2x + x + 6 = $54

4x = $48

x = $12

So madision be $12

Jasmine be $24

And, the devanie be $18

Answer:

  $11,988

Step-by-step explanation:

A graphing calculator gives you the answer easily.

The minimum unit cost is $11,988.

__

The equation for unit cost can be put into vertex form to find the minimum.

  C(x) = 0.7x^2 -210x +27738

  C(x) = 0.7(x^2 -300x +150^2) +27738 -0.7(150^2)

  C(x) = 0.7(x -150)^2 -11,988

This is vertex form:

  C(x) = a(x -h)^2 +k . . . . . . . where (h, k) is the vertex.

The vertex of this cost function is (150, 11,988).

The minimum unit cost occurs when 150 engines are produced. That unit cost is $11,988.

the answer is $11,988

1/4x²+11=38
solve by square root method

Answers

1/4 x^2 + 11 = 38

multiply both sides by 4

x^2 + 44 = 152

x^× = 152 - 44

x^2 = 108

x = + or - 6 square root of 3

x¹ = -6 square root of 3

x² = +6 square root of 3

Is 16t - 3t equivalent 3t - 16t

Answers

Answer:

No, 16t -3t equals 13t while 3t - 16t equals -13t

Answer:

No,

16t= 16x2=32

3t=3x2=6

32-6=26

3t=3x2=6

16x2=32

6-32=-26

Hisako sells dolls at her doll store. If she sells a doll for $35, and there is 6% sales tax, what is the tax amount a customer will pay on one doll?

Answers

Given:

The price of a doll = $35

Sales tax = 6%

To find:

The tax amount that a customer will pay on one doll.

Solution:

The price of doll is $35 and the sales tax is 6%, so the tax amount on a doll is 6% of 35.

[tex]\text{Tax amount}=35\times \dfrac{6}{100}[/tex]

[tex]\text{Tax amount}=\dfrac{210}{100}[/tex]

[tex]\text{Tax amount}=\dfrac{21}{10}[/tex]

[tex]\text{Tax amount}=2.1[/tex]

Therefore, the tax amount that a customer will pay on one doll is $2.1.

Step-by-step explanation:

Given: [tex]f(x)=4x-2[/tex]

To find:  average rate of change of the function [tex]f(x)=4x-2[/tex] over the interval [tex]x=-1[/tex] and [tex]x=2[/tex]

Solution:

Take [tex]a=-1,\,b=2[/tex]

[tex]f(a)=f(-1)\\=4(-1)-2\\=-4-2\\=-6\\\\f(b)=f(2)\\=4(2)-2\\=8-2\\=6[/tex]

Average rate of change of the function [tex]=\frac{f(b)-f(a)}{b-a}[/tex]

[tex]=\frac{f(2)-f(-1)}{2-(-1)}\\\\=\frac{6-(-6)}{3} \\\\=\frac{12}{3}\\\\=4[/tex]
