Answer:

All real numbers

Step-by-step explanation:

The domain represents the x-coordinates, so you can see on the graph that it goes all the way out to both the left and right directions, meaning it covers all the negative numbers, and all the positive numbers. The question is trying to trick you into thinking about the range, but forget about the y-axis for this one.

Answer:

All real numbers or the second choice

Step-by-step explanation:

Answer:

C. y = -2x - 1

Step-by-step explanation:

y = mx + b

The slope is going down so that means that the m will be negative.

We are left with two choices:

y = -2x - 1

y = -2x + 1

Check the graph again to find what point does the line intersect the vertical line (y-axis). That hits in (0, -1) or -1.

So the only answer applicable is option C.

Answer:

x = 3

y = -1

Step-by-step explanation:

in this system, we are given that y = x - 4

this means that we can take the other equation and replace y with x - 4:

so 2x - 3y=9 turns into

2x -3 (x - 4) = 9

distribute -3 to x and -4:

2x - 3x + 12 = 9

add like terms and subtract 12 from both sides

-x = -3

divide both sides by -1 to get rid of the negative on x:

x = 3

now we have the value of x, so we can replace the x in y = x - 4 with the value we just got

so y = x- 4 turns into

y = (3) - 4

solve and you get

y = -1

t = 8.69 s

Step-by-step explanation:

The height h of the rocket in feet above the surface of the lake can be modeled by :

[tex]h=340+100t-16t^2[/tex]

Let we need to find the time to reach the ground. When it reach the ground, h = 0

[tex]340+100t-16t^2=0[/tex]

We need to find the value of t.

t = 8.69 s and -2.45 s

Neglecting negative value,

t = 8.69 s

Hence, it will take 8.69 s to reach the ground.

Answer:

Step-by-step explanation:

The fraction of the students finished in less than 20 minutes is 2/3

A fraction represents a part of a number or any number of equal parts.

A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.

We are given the table of the time it took a group of students to complete a puzzle.

Here we can see that total frequency is 24, and the frequency that finished in less than 20 min is 16,

This means the frequency that depends on the number of students.

Therefore, 16/24 = 2/3

Answer:

6849.4

Step-by-step explanation:

m(r)(r) mass and radius equals N

The magnitude of the gravitational force  on Mars is 3.6N

Newton's law of gravitation states that the force is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them. It is given by:

F = G(m₁m₂)/r²

where m₁ and m₂ are mass, r is the distance, G is constant = 6.67 * 10⁻11 Nm²/kg² and F is the force.

Given m₁ = m₂ = 6.34 * 10²³, F = 3.43 x 10⁶, hence:

F = 6.67 * 10⁻¹¹(6.34 * 10²³)² / ( 3.43 x 10⁶)²

F = 3.6N

Hence the magnitude of the gravitational force  on Mars is 3.6N.

Answer:

$15.12

Step-by-step explanation:

{10 * 0.08 = 0.8

4 * 0.08 = 0.32} (Brackets are here so you can see what I did easier and so you could see how to do it mentally.)

[0.8 + 0.32 = 1.12]

14 + 1.12 = 15.12

David is buying a cheese wheel priced at $14 on 8% sales tax.

David's pays for the cheese wheel is $15.12 .

Given:

Before-tax, the price of cheese wheel = $ 14

Sales tax on cheese wheel = 8%

Sales tax is 8% of $14

[tex]=\frac{8(14)}{100} = \frac{112}{100} = 1.12[/tex]

So, the sales tax on the cheese wheel is $1.12

The total price of the cheese wheel, including tax = $ 14 +  $1.12 = $15.12

Therefore, David's pays for the cheese wheel is $15.12 .
