I Need Help With Number 3 Plzzz Fast

Answers

Answer 1

Step-by-step explanation:

the domain is the interval of the x (input) values.

in other words, is g(x) invalid for certain x ?

it does not look like it. it looks like g(x) is valid for every possible value of x from -infinite to +infinite.

the range is the interval of possible y (functional) values.

and that is clearly valid for every y between -1 and +infinity.

1.Modeling with mathematics: The total cost C (in dollars) to participate in a ski club is given by the literal equation C=85x+60, where x is the number of ski trips you take.

a. Solve the equation for x.

b. How many ski trips do you take if you spend a total of $315 and $485?​

Answers

Part (a)

We have some unknown number x which is a placeholder for a positive whole number (eg: x = 4).

What's happening to x are these two things, in this exact order

Multiply by 85Add 60

We multiply first, then add. The order is important. We're following the order of operations PEMDAS here. If we knew what x was, then we'd go forward in the PEMDAS chain; however, we don't know what x is. So we go backwards in the chain to isolate x. This will undo every operation applied to x.

So,

C = 85x+60

C-60 = 85x

85x = C-60

x = (C-60)/85

In the second step, I subtracted 60 from both sides to undo the "plus 60" operation. Then in the last step, I divided both sides by 85 to undo the multiplication.

Answer:   x = (C-60)/85

===============================================================

Part (b)

How many ski trips can we take if we spend $315? We simply plug in C = 315 into that equation we just found at the end of part (a).

Doing so gets us...

x = (C-60)/85

x = (315-60)/85

x = 255/85

x = 3

We can take 3 ski trips if we spent a total of $315

Repeat the same steps for C = 485

x = (C-60)/85

x = (485-60)/85

x = 425/85

x = 5

We can take 5 ski trips if we spent a total of $485

Note how plugging something like x = 5 into the original equation yields:

C = 85x+60

C = 85*5+60

C = 425+60

C = 485

Showing that x = 5 leads to C = 485. This helps confirm the second answer. I'll let you check the first answer.

Uhm, I think is 0.38

If a female is chosen, then the probability that she is satisfied with the company's customer service is 0.24.

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, A credit card company surveys 125 of its customers to ask about satisfaction with customer service. The results of the survey, divided by gender, are shown below.

                                     Males                           Females

Extremely Satisfied          25                              7

Satisfied                            21                              13

Neutral                              13                               16

Dissatisfied                        9                                14

Extremely Dissatisfied       2                                 5

Here, the total number of customers is 125. (N=125).

If a female is chosen, find the probability that she is satisfied with the company's customer service. Here, conditional probability is used.

[tex]P(satisfied|female) = \frac{P(satisfied and female)}{P(females)} \\Here\\P(satisfied|female) = \frac{n(satisfied and female)}{N} \\= \frac{13}{125} \\= 0.104\\P(female) = \frac{n(female)}{N} \\= \frac{55}{125} \\= 0.44\\Now, \\P(satisfied|female) = \frac{n(satisfied and female)}{P(female)} \\= \frac{0.104}{0.44}\\= 0.24[/tex]

Hence, if a female is chosen, then the probability that she is satisfied with the company's customer service is 0.24.

Rational numbers are numbers that can be written as a fraction of two integers (as long as the denominator isn’t 0).

5 = 5/1, so it’s rational
1/2 and 1/3 are fractions, so they’re rational.

As decimals, rational numbers either stop or repeat.

Hello there!

[tex] \displaystyle \large{ \sin (2 \theta) = 2 \sin \theta \cos \theta} \\ \displaystyle \large{ \cos (2 \theta) = \begin{cases} 2 { \cos}^{2} \theta - 1 \\ 1 - 2 { \sin}^{2} \theta \\ { \cos}^{2} \theta - { \sin}^{2} \theta \end{cases}}[/tex]

First, we have to find cos(theta). We know that the theta lies in Q3 which is negative for both sin and cos. To find cos, you can use the identity or Pythagoras.

Recall

[tex] \displaystyle \large \tt{ \sin \theta = \frac{opposite}{hypotenuse} } \\ \displaystyle \large \tt{ \cos \theta = \frac{adjacent}{hypotenuse} }[/tex]

Finding cos, I will use Pythagoras.

Recall Pythagorean

Define a or b = adjacent or oppositeDefine c = hypotenuse

[tex] \displaystyle \large{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]

From sin = -1/6

opposite = 1hypotenuse = 6adjacent = x

[tex] \displaystyle \large{ {1}^{2} + {b}^{2} = {6}^{2} } \\ \displaystyle \large{1 + {b}^{2} = 36 } \\ \displaystyle \large{ {b}^{2} = 36 - 1 } \\ \displaystyle \large{ {b}^{2} = 35 } \\ \displaystyle \large{ {b} = \sqrt{35} }[/tex]

b is our adjacent. Hence,

[tex] \displaystyle \large{ \cos \theta = \frac{ \sqrt{35} }{6} }[/tex]

Since theta is in Q3, cos < 0 or in negative.

[tex] \displaystyle \large{ \cos \theta = - \frac{ \sqrt{35} }{6} }[/tex]

Finding sin(2theta)

[tex] \displaystyle \large{ \sin \theta = - \frac{ 1 }{6} }[/tex]

Hence,

[tex] \displaystyle \large{ \sin 2 \theta = 2( - \frac{ 1 }{6} )( - \frac{ \sqrt{35} }{6}) } \\ \displaystyle \large{ \sin 2 \theta = ( - \frac{ 1 }{3} )( - \frac{ \sqrt{35} }{6}) } \\ \displaystyle \large{ \sin 2 \theta = \frac{ \sqrt{35} }{18} }[/tex]

Recall

Negative × Negative = Positive

Finding cos(2theta)

The cos of 2theta has multiple formulas. All of them are same and also identity to each others.

I will be using the first one as it only involves cos, not sin.

[tex] \displaystyle \large{ \cos \theta = - \frac{ \sqrt{35} }{6} }[/tex]

Therefore,

[tex] \displaystyle \large{ \cos2 \theta = 2 { ( - \frac{ \sqrt{35} }{6} )}^{2} - 1 } \\ \displaystyle \large{ \cos2 \theta = 2 (\frac{ 35}{36}) - 1 } \\ \displaystyle \large{ \cos2 \theta = \frac{ 35}{18} - 1 } \\ \displaystyle \large{ \cos2 \theta = \frac{ 35}{18} - \frac{18}{18} \longrightarrow \boxed{\frac{17}{18} }}[/tex]

Answer

sin(2theta) = √35/18cos(2theta) = 17/18

  r = 2

Step-by-step explanation:

"A varies inversely with r cubed" means the relation is of the form ...

  A = k/r³

We can find the value of k as ...

  k = Ar³ = 72·5³ = 9000 . . . . . . . multiply the above relation by r³

And we can solve this for r to get ...

  r³ = 9000/A . . . . . . divide by A

  r = ∛(9000/A) . . . . . take the cube root

So, for A = 1125, we have ...

  r = ∛(9000/1125) = ∛8

Answers

The statement "a system that consists of a linear equation and a quadratic equation can have zero, one, or two solutions" is true .

What is linear equation?

A linear equation is an algebraic equation of the form [tex]y= mx+b.[/tex]involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.

What is quadratic equation?

We define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is , [tex]y = ax^2 + bx + c[/tex]

where a, b, and c are numbers and a cannot be 0.  

According to the question

A system that consists of a linear equation and a quadratic equation can have zero, one, or two solutions.​

This statement is true as

if we see graphically  

A quadratic equation is a parabola and a linear equation is a straight line.

There could be 3 situations of intersection of line and parabola

1. straight line never crosses the parabola

i.e line passing above or below parabola without touching

it is called zero solution

2. where the straight line is a tangent to the parabola, 'touching' it at only one point.

i.e single point lies in both line and parabola

it is called one solution

3. the line cuts across the parabola, it will cut the parabola at 2 points

it is called two solution .
