Ivan3 years ago
6 0

The greatest number of rows Li Na can plant is 9

<h3><u>Solution:</u></h3>

Given that Li Na is going to plant 63 tomato plants and 81 rhubarb plants

Li Na would like to plant the plants in rows where each row has the same number of tomato plants and each row has the same number of rhubarb plants

<em><u>To find: greatest number of rows Li Na can plant</u></em>

To find the greatest number of rows of plants we have to list the factors of 63 and 81 and find the greatest common one

The factors of 63 are: 1, 3, 7, 9, 21, 63

The factors of 81 are: 1, 3, 9, 27, 81

Then the greatest common factor of 63 and 81 is 9

Thus greatest number of rows Li Na can plant is 9

Pls help me I rlly don’t get it :(

Step-by-step explanation:

Use SOH-CAH-TOA.

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Let's start with #12.  The hypotenuse is 18.  The side adjacent to ∠B is 6.  Since we have the adjacent side and hypotenuse, we should use cosine.

cos B = 6/18

Solving for B:

B = cos⁻¹(6/18)

Using a calculator:

B ≈ 70.5°

Now let's do #14.  The side adjacent to ∠B is 19, and the side opposite of ∠B is 22.  Since we have the adjacent side and opposite side, we should use tangent.

tan B = 22/19

Solving for B:

B = tan⁻¹(22/19)

Using a calculator:

B ≈ 49.2°

Which equation represents the graphed function?
dezoksy [38]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = \frac{0+3}{2-0} = \frac{3}{2}

note the line crosses the y- axis at (0, - 3) ⇒ c = - 3

y = \frac{3}{2} x - 3 → C

The height of a rocket a given number of seconds after it is released is modeled by h (t) = negative 16 t squared 32 t 10. What
V125BC [204]

The variable t represents the number of seconds that have passed after the release of the rocket.

<h3>Function</h3>

The function can be defined as an expression that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The height of a rocket a given number of seconds after it is released is modeled by,

h(t) = 6t^2 + 32t + 10

As given in the above function, h (height) is the dependent variable which depends on the number of seconds t after the rocket is released (independent variable).

Hence we can conclude that the variable t represents the number of seconds after the rocket has been released.

To know more about the function, follow the link given below.
