Given that point (-5, -6) is a point on the terminal side of <span>θ. Since both the x coordinate and the y-coordinate are negative, </span><span>θ is in the third quadrant.

The side opposite </span><span>θ is -6 and the side adjacent </span><span>θ is -5.

The hypothenus is given by \sqrt{(-6)^+(-5)^2}=\sqrt{36+25}=\sqrt{61}

The exact value of cos</span><span>θ is given by:

\cos\theta= \frac{adjacent}{hypothenuse} = \frac{-5}{\sqrt{61}}

</span>The exact value of csc<span>θ is given by:

\csc\theta= \frac{hypothenuse}{opposite} = \frac{\sqrt{61}}{-6}</span>

The exact value of tan<span>θ is given by:

\tan\theta= \frac{opposite}{adjacent} = \frac{-6}{-5} =1.2</span>

Answer:

Slope(m)=3

Y-intercept= 0

y = 3x +0

Proportional

Step-by-step explanation:

m = -6--12/-2--4

m=6/2

m=3

-12 = 3(-4) + b

-12 = -12 + b

Cole has a rectangular garden with an area of 16.02 square meters. What is the width, in meters, of the garden?
exis [7]

Answer:

3.56m

Step-by-step explanation:Parameters given:

Area of the rectangular garden = 16.02m^2

Length of the rectangular garden = 4.5m

The Area of a rectangle can be calculated for using the formula below

Area (square meters) = length (meters) × width (meters)

Therefore, 16.02m^2 = 4.5m × width

Width = 16.02m^2 / 4.5m

Width = 3.56m

Therefore the width in meters of the garden is 3.56m

See the attachment below for an illustrative diagram

A = area

l = length

w = width

etermine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 3 2 x
nata0808 [166]

Answer:

(32/15, -2/5)

Step-by-step explanation:

(1) ³/₂x   -    2y =  4

(2)   x  +    ⅓y =  2

(3)  3x   -     4y =  8              Multiplied (1) by 2

(4)  3x  +       y =  6              Multiplied (2) by 3

                  5y = -2              Subtracted (3) from (4)

(5)                 y = -⅖             Divided each side by 5

       x + ⅓(-⅖) =  2              Substituted (5) into (2)

       x  -  ²/₁₅    =  2

       x              =  2 + ²/₁₅     Added ²/₁₅ to each side

      x              = 32/15

The system of equations has only one solution: (32/15, -2/5).
