Answer:

B

Step-by-step explanation:

Using the trigonometric identities

• cscx = \frac{1}{sinx} and secx = \frac{1}{cosx}

Consider the left side

cscx sec x = \frac{1}{sinx} × \frac{1}{cosx} = \frac{1}{sinxcosx}

Consider the right side

2 csc2x = \frac{2}{sin2x} = \frac{2}{2sinxcosx} = \frac{1}{sinxcosx}

left side = right side hence identity is verified

Find the slope of the line
natta225 [31]

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (2, 1)

m = \frac{1-4}{2+1} = \frac{-3}{3} = - 1

egoroff_w [7]

Answer:

f(-1) = -12

Step-by-step explanation:

<u>Step 1:  Set x to -1 and solve</u>

<u />f(x) = -3x^2+2x-7

f(-1) = -3(-1)^2+2(-1) - 7

f(-1) = -3(1) - 2 - 7

f(-1) = -3 - 2 - 7

f(-1) = -12

Answer:  f(-1) = -12
