Which of the following figures has reflectional symmetry? Help !!

aliya0001 [1]

Answer:

Figure D. (A)

When you flip the figure across like a mirror, it remains the same shape as the other side. An easy way to determine this is by cutting a line down the middle.

Reflectional symmetry states that if there exists at least one line that divides a figure into two halves such that one-half is the mirror image of the other half.

Edit: Typo!

Given sinθ = 2/5 and cosθ < 0: 1. Find cscθ 2. Find cotθ

Tems11 [23]

Recall that

sin²(θ) + cos²(θ) = 1

for all θ, and given that cos(θ) < 0, we find that

cos(θ) = -√(1 - sin²(θ)) = -√(1 - (2/5)²) = -√(21)/5

Now,

csc(θ) = 1/sin(θ) = 1/(2/5) = 5/2

and

cot(θ) = cos(θ)/sin(θ) = (-√(21)/5)/(2/5) = -√(21)/2

Answer:

(a) The range of the function represents the set of values on the y-axis. We see that function has an absolute maximum, then the range of the function is:

$Ran\{f(x)\} = (-\infty, 4]$

(b) The location of the maximum is represented by its ordered pair. After direct observation, we located this maximum at $(x, f(x)) = (-1.3, 4)$

(c) By direct observation we find that the value of $y$ when $x = 1.5$ is -12.

(d) By direct observation we conclude that the values of $x$ when $y = -20$ are -4.8 and 2.

So one miles for A and the fee is $170 then B is $160 then if you used company A you'd go 3 miles to match company B which their miles would be 2,
