Which expression is equivalent to -2 1/4÷ (-2/3)​
Talja [164]

Answer:

-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)=\dfrac{27}{8}=3\dfrac{3}{8}}

Step-by-step explanation:

-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)\qquad\text{the quotient of two negative numbers is positive}\\\\=2\dfrac{1}{4}\div\dfrac{2}{3}\qquad\text{convert the mixed number to the improper fraction}\\\\=\dfrac{2\cdot4+1}{4}\div\dfrac{2}{3}=\dfrac{9}{4}\div\dfrac{2}{3}\\\\\text{dividing by a fraction is the same as multiplying by its reciprocal.}\\\\=\dfrac{9}{4}\cdot\dfrac{3}{2}=\dfrac{9\cdot3}{4\cdot2}=\dfrac{27}{8}\qquad\text{convert to the mixed number}\\\\=3\dfrac{3}{8}

given that sine theta = 0, and cosine theta is less than zero, find the exact values of the other two trig functions
vekshin1

Answer:

θ = π + periods of 2π

Sin (π + 2π) = 0

Cos (π + 2π) = -1

Tan (π + 2π) = 0

Step-by-step explanation:

Sin (θ)=0 implies that θ only can be 0 or π plus periods of 2π:

θ = 0+2π

θ = π+2π

For Cos(θ) the values only can be:

Cos (0+2π) = 1 and

Cos (π+2π) = -1

from this, only Cos (π+2π) < 0

So θ only can be θ=π+2π

For the perimeter you have to consider the EXTERNAL SHAPE ONLY:

a) the perimeter of half a circle WITHOUT ITS DIAMETER  is:
π.R - 2R → 3.14x1.5 - 2x1.5 → 1.71 cm

b) the perimeter of the rectangle WITHOUT THE UPPER SIDE is:
2.5+3+2.5 = 8 cm

Hence the perimeter of the figure is 1.71 + 8 = 9.71 cm

2) Area of the figure:
Area of half circle is π.R²/2 →3.14 x (1.5)²/2 → Area half circle = 3.5325 cm²
Area of rectangle = 2.5 x 3 = 7.5 cm²
Total area = 3.5325 + 7.5 = 11.0325 ≈ 11 cm²
