What is the domain of the function y= (square root) x+4

Answers

Answer 1

Answer:

0 ≤ x ≤ ∞

Step-by-step explanation:

Square roots always need to be either equal to or greater than zero because it should be positive inside (unless we're working with imaginary numbers).

So the domain would be that x ≥ 0 (or the third choice ⇒ 0 ≤ x ≤ ∞).

A television channel broadcasts a baseball game every day. Yesterday's broadcast showed the game for 2 5/6 hours and commercials for 2/3 hour. At this rate, how many hours does the television channel show a game for every hour it shows commercials during its broadcasts?

Answers

Answer:

4.25 hours

Step-by-step explanation:

Given that :

Game broadcast time = 2 5/6 hours = 17/6 hours

Commercials time = 2/3 hours

2/3 hours of commercials = 17/6 of game broadcast

1 hour of commercials = x hours of game broadcast

Cross multiply ;

(2/3)x = 17/6

2x * 6 = 17 * 3

12x = 51

x = 51 / 12

x = 4.25

For every hour it shows commercials, game is broadcasted for 4.25 hours

Find the value of x, image attached below

Answers

Answer:

x = 10

Step-by-step explanation:

Sum of angles in a triangle is 180° , so

35° + (5x + 7)° + (9x - 2)° = 180°

The value of x can now be found by solving the linear equation.

5x + 9x + 35 + 7 - 2 = 180

14x + 40 = 180

14x = 180 - 40

14x = 140

x = 140/14

x = 10

Answers

Answer:

0.21875

Step-by-step explanation:

if the common ratio is 0.5 keep multiplying till the eight term

3.5 ×0.5=1.75 fifth term

1.75×0.5=0.875 sixth term

0.875×0.5=0.4375 seventh term

0.4375×0.5=0.21875 eight term

how many possibilities are there if you toss coin 7 times

Answers

each toss results in 2 possible outcomes, head or tail so the number of possible outcomes for 7 would be

Answer:

2^7

2x2x2x2x2x2x2 = 2^7

2^7 because each time you flip the coin there can be two outcomes (heads or tails) and you have to multiply by 2 each time (2x2x2x2x2x2x2) to account for all the different possibilities for instance you could flip heads, tails, heads, heads, tails, tails, tails or you could flip tails, tails, tails, heads, heads, tails, heads or all heads or all tails which is why it’s 2^7

C=20+30×
He starts a job at 9 30 and finishes at 1 pm
Work out his charge for this job

Pls show me formula

Answers

Answer:

c=$125

Step-by-step explanation:

9:30--12:30 is three hours, then another half hour till 1pm total hours is 3.5

c = 20+30*3.5

c=20 + 105

c = 125

The charge for Piere's work is $125 by using the formula C = 20+30x.

What is a linear equation?

A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. An equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

For the given situation,

Let the amount in dollar,$ be C.

Let the hours be x.

The equation is C = 20+30x.

He starts a job at 9:30 and finishes at 1 pm. So, the time x is 3.5 hours.

⇒ [tex]1pm-9:30 am=3.5 hours[/tex]

Thus charge for the electrician is

⇒ [tex]C=20+30(3.5)[/tex]

⇒ [tex]C=125[/tex]

Hence we can conclude that the charge for Piere's work is $125 by using the formula C = 20+30x.

Using the dimensions shown, you could create a rectangular prism. Caculate the surface area for the rectangular prism. A 30m2 b 56m2 c 60m2 d 112m2

Answers

Answer:

550ft²

Step-by-step explanation:

Since we are not given the dimension of the rectangular prism. Let us assume;

Length of the rectangular base L = 10ft

Width of the rectangular base W = 15ft

height of the prism H = 5ft

Total surface area of the prism = 2(LW + WH + LH)

Substitute the given values

Total surface area of the prism = 2{10*15 + 15*5 + 10*5}

Total surface area of the prism = 2(150+75+50)

Total surface area of the prism = 2(275)

Total surface area of the prism = 550ft²

Michael has $68. Craig has $24 less than Michael has. Michael spends $20 on a new hat. Part A: Write an equation where the solution represents the amount of money (x), in dollars, Craig has after Michael buys the hat. Explain how you came to this equation. Part B: Now, Craig buys some socks. He has $16 left. Write an equation where the solution represents the amount of money (y), in dollars Craig spent on socks. Show how you know this is the correct equation.

Answers

Answer:

a) x + 4 = 48

b) y + 16 = 44

Step-by-step explanation:

a) Michael has $28 and Craig has $24 less than Michael. Let x represent the amount of money that Craig has. Hence:

x = 68 - 24

x + 24 = 68

Given that Michael spends $20 on a new hat. Therefore we subtract 30 from both sides of the equation:

x + 24 - 20 = 68 - 20

x + 4 = 48

x = $44

b) If y represent the amount of money that Craig spent on buying socks. He has 16 remaining.

Therefore:

44 - y = 16

y + 16 = 44

y = $28
