The correct answer is quadrant. 

Quadrant is a method used to determine latitude. Chronometer is used to measure time. Astrolabe is used by navigators and astrologers. Cross-staff or Jacob's staff is used to measure angles. So the correct answer would be quadrant. I hope this helped you.

2.<br> If y = V9 – 3x, determine the value of x for which y will be a real number.
Pepsi [2]

Answer:

x ≤ 3

Step-by-step explanation:

The expression inside the radical ≥ 0, thus

solve

9 - 3x ≥ 0 ( subtract 9 from both sides )

- 3x ≥ - 9

Divide both sides by - 3, reversing the symol as a result of dividing by a negative quantity

x ≤ 3

Any value of x less than or equal to 3 ensures \sqrt{9-3x} is real

PLEASE HELP!!
vesna_86 [32]

Answer:

k=-3

x=63

Step-by-step explanation:

The equation for direct variation is

y = kx  where k is the constant of variation

We know x and y we can solve for k

-87 = k*29

Divide each side by 29

-87/29 = k

-3 =k

y= -3x

Now we know y = -189, we can find x

-189 = -3x

Divide by -3

-189/-3 = -3x/-3

63 =x

Help solve w(5w^3)^-2 / w^-4
Bond [772]
Start with the exponents, 3 and -2, you multiply them together so you get -6 so its w(w^-6)/w^-4 and then you do wx5w^-6 which is 5w^-4 bc im pretty sure you multiply it to 5w and thats 5w squared so you just add it and so it becomes 5w^-4/5w^-4 and you can simplify that

A function is shown: f(x) = 36x2 − 1.
german

Answer:

The equivalent function: f(x)=(6x+1)(6x-1)

Step-by-step explanation:

The x-intercepts of the given function on the graph can be obtained by equating the function to zero.

This is because on the x-axis, the y-coordinate is zero.

36x^{2} -1=0\\36x^{2} =1\\x=\frac{1}{6},-\frac{1}{6}

The function that has the same x-intercepts on the graph from the given options is:

f(x)=(6x+1)(6x-1)

Alternate Method:

The answer can also be obtained by factorizing the question.
