Bot 2 will click more times in 10 seconds, because when you divide 16 by 2 to get its unit rate it is 8 clicks per second. Times that by 10 and you only get 80, whereas if you divide 30 by 3 the unit rate is 10. At this rate, by 10 seconds it will have clicked 100 times. Bot 2 clicks 20 more times than Bot 1 in 10 seconds.

lara31 [8.8K]

Answer:

D(t)=-24t+166

Step-by-step explanation:

Let

D(t) = the distance to the safe zone (measured in meters)

t = time (measured in seconds)

<u>Given:</u>

Rachel's rate = 24 meters per second

At t_1=4 seconds D(t_1)=70 meters

<u>Find:</u> D(t)

Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.

Hence, the function expression is

D(t)=-24t+b

To find b, substitute t_1=4 and  D(t_1)=70:

70=-24\cdot 4+b\\ \\70=-96+b\\ \\b=70+96\\ \\b=166

So,

D(t)=-24t+166

How do u work this out and what's the answer
I am Lyosha [343]
1) you would need to turn both fractions so they have a common denominator, that would be 2 2/4 and 3/4
2) then subtract : 2 2/4 - 3/4, and you would subtract numerators and the whole number, but you keep the denominator the same. However, you cannot subtract 2 and 3 in this case, so you need to change 2 2/4 to 1 5/4 (they are still equivalent)
3) 1 5/4 - 3/4 = 1 2/4, which simplified version is 1 1/2
Therefore, the answer is 1 and 1/2

Quadrilateral A B C D is shown. Sides A D and B C are parallel. Sides A B and C D are congruent. Angle A is 115 degrees. What is
brilliants [131]

Step-by-step explanation:

Since sides AD and BC are parallel,

Angle BAD + Angle ADC = 180° (co-interior angles)

Therefore Angle ADC = 180° - 115° = 65°.

If anyone can please help me
MA_775_DIABLO [31]

Answer:

1/4

Step-by-step explanation:

5 orange + 5 mango = 10

P( mango ) = mango /total = 5/10 = 1/2

Replace

5 orange + 5 mango = 10

P(orange ) = orange /total = 5/10 = 1/2

P(mange, replace, orange) = 1/2 * 1/2 = 1/4

Is 0.2x = 100- 0.4/y linear or non linear function?
Pavel [41]

so i will not give you the answer i will teach you how to do it.

In Mathematics, you must have learned about different types of equations. Here, we are going to discuss the difference between linear and nonlinear equations. The difference between them described here with the help of definitions and examples.

We come across a lot of equations while solving maths problems. Some equations include only numbers and some consist of only variables and some consists of both numbers and variables. Linear and nonlinear equations usually consist of numbers and variables.

Definition of Linear and Non-Linear Equation

Linear means something related to a line. All the linear equations are used to construct a line. A non-linear equation is such which does not form a straight line. It looks like a curve in a graph and has a variable slope value.

The major difference between linear and nonlinear equations is given here for the students to understand it in a more natural way. The differences are provided in a tabular form with examples.

What is the difference between Linear and Nonlinear Equations?

To find the difference between the two equations, i.e. linear and nonlinear, one should know the definitions for them. So, let us define and see the difference between them.

Linear Equations  

Non-Linear Equations

It forms a straight line or represents the equation for the straight line It does not form a straight line but forms a curve.

It has only one degree. Or we can also define it as an equation having the maximum degree 1. A nonlinear equation has the degree as 2 or more than 2, but not less than 2.

All these equations form a straight line in XY plane. These lines can be extended to any direction but in a straight form. It forms a curve and if we increase the value of the degree, the curvature of the graph increases.

The general representation of linear equation is;

y = mx +c

Where x and y are the variables, m is the slope of the line and c is a constant value.

The general representation of nonlinear equations is;

ax2 + by2 = c

Where x and y are the variables and a,b and c are the constant values

Examples:

10x = 1

9y + x + 2 = 0

4y = 3x

99x + 12 = 23 and

Examples:

x2+y2 = 1

x2 + 12xy + y2 = 0

x2+x+2 = 25

Note:

The linear equation has only one variable usually and if any equation has two variables in it, then the equation is defined as a Linear equation in two variables. For example, 5x + 2 = 1 is Linear equation in one variable. But 5x + 2y = 1 is a Linear equation in two variables.

Let us see some examples based on these concepts.

Solved Examples

Example: Solve the linear equation 3x+9 = 2x + 18.

Solution: Given, 3x+9 = 2x + 18

⇒ 3x - 2x = 18 - 9

⇒ x = 9

Example: Solve the nonlinear equation x+2y = 1 and x = y.

Solution: Given, x+2y = 1

x = y

By putting the value of x in the first equation we get,

⇒ y + 2y = 1

⇒ 3y = 1

⇒ y = ⅓

∴ x = y = ⅓

What is the key difference between non-linear and linear equations?

A linear equation is used to represent a straight line in a graph, whereas non-linear equations are used to represent curves.

How does the graph of linear and non-linear equations look?

A linear equation graph is a constant slope whereas the graph of the non-linear equation shows the variation in slope at different points.

How is the linear equation represented? Give an example.

The general representation of linear equation is y = mx+c,

where m = slope of the line

x and y are the variables

c is the intercept (constant value)

Example: 2x+y=1

y=-2x+1

How is the nonlinear equation formed?

A non-linear equation is generally given by ax2+by2 = c

where x and y are variables

a,b and c are constant values.
