m = -2/-4

m = 1/2

Answer: 3 × 10^4

Step-by-step explanation:

9x10^2 is how many times as much as 3x10^-2?

9 × 10^2 = 9 × 100 = 900

3 × 10^-2 = 3 × 0.01 = 0.03

We then divide, this will be:

= 900/0.03

= 30000

This can be represented as:

30000 = 3 × 10^4

It can be clearly seen that 9 x 10^2 is is 3 x 10^4​ times of the number 3 x 10^-2.

Multiplication is one of the basic mathematical operations. When a number is multiplied by another, the it is a given number of times that number.

As such, we can we that 9 x 10^2 is is 3 x 10^4​ times of the number 3 x 10^-2.

Step-by-step explanation:

Answer: store 1 f(X)= 70+2.50X Store 2 f(x) 60+5x

Step-by-step explanation: So i gave you the equations because i don't really understand the what  its asking me for and the lower price is store 1

The equations that represents the two stores are as follows;

f(x) = 70 + 2.50x

g(x) = 60 + 5x

The situation can be modelled to a linear equation.

Therefore,

y = mx + b

Answer:

[tex]x=0, g(x) =-4[/tex]

Step-by-step explanation:

Given that:

Graph of [tex]g(x)=3|x|-4[/tex] represents the path of a person from their house to school and then from school to their friend's house.

First of all let us learn about the graph of an absolute function.

An absolute function first decreases and then starts increasing from one point.

At that point, value of [tex]x=0[/tex].

As per the problem statement given, the location of the school can only be the point that we have discussed above.

Given that the equation is:

[tex]g(x)=3|x|-4[/tex]

Let us put the value of [tex]x=0[/tex]

[tex]g(x)=3|0|-4\\\Rightarrow g(x)=-4[/tex]

Therefore, the location of the school is:

(0, -4)  or [tex]x=0, g(x) =-4[/tex]

Answer: they need 13.86 minutes to chop 14 pounds of carrots.

Step-by-step explanation:

Rohan can chop 6 pounds of carrots in 11 minutes, then he can chop:

6lb/11min = 0.55 pounds per minute.

Lewis can chop 6 pounds in 13 minutes, then he can chop:

6lb/13min = 0.46 pounds per minute.

Working together, they can chop:

0.55 lb/min + 0.46lb/min = 1.01 lb/min

So working together, they can chop 1.01 pounds per minute.

Now we want to answer:

how many minutes will it take for Rohan and Lewis to chop 14 pounds of carrots?

If they need a time T, we will have the equation:

(1.01 lb/min)*T = 14 lb

T = 14lb/(1.01 lb/min) = 13.86 min

This means that they need 13.86 minutes to chop 14 pounds of carrots.

Answer:

y = Asin(Bx-C) + D

D is midline.  A is amplitude.  Period is 2π/|B|  (More useful for graphing and shows the effect of B).  Strictly speaking, the frequency is the inverse of period:  f = |B|/(2π), but a lot of math texts say frequency when they mean angular frequency which is rad/s vs. cycles/sec.  The angular frequency ω = 2πf  (2π rads/cycle) or just |B|.  Finally the function is translated to the right  C/B (to the left if C/B is negative)

Step-by-step explanation:

The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be y = 4 sin(2πx) + 3.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The sinusoidal function is given as,

y = A sin(2πx + ∅) + k

Where 'A' represents the amplitude, '∅' represents the phase difference, '2πx' represents the time period, and 'k' represents the midline.

The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be given as,

y = 4 sin(2πx) + 3

The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be y = 4 sin(2πx) + 3.

Answer:

24

Step-by-step explanation:

Given that:

Total number of members who race = 18

Ratio of racers to divers = 6 : 2

To find:

Total number of members of the team = ?

Solution:

Given the ratio = 6 : 2

As per the ratio given, we can let the number of racers = [tex]6x[/tex]

and

As per the ratio given, we can let the number of divers = [tex]2x[/tex]

As the swim team members can either race or dive, we can say that:

Total number of members on the team = Number of racers + Number of divers

Total number of members on the team = [tex]6x+2x=8x[/tex]

As per the question statement, we are given that:

[tex]6x=18\\\Rightarrow x =\dfrac{18}{6}\\\Rightarrow x =3[/tex]

Therefore, total number of team members = 8 [tex]\times[/tex] 3 = 24
