So if f(-3), then x = -3.


Substitute.



y = -(-3)^2 + 6

= -(9) + 6

= -3


Hope it helped

Using these coordinates, find the slope. (0, -6), (3, -2)
seropon [69]

Answer:

The slope between the points (0, -6) and (3, -2) will be:

  • m=\frac{4}{3}

Step-by-step explanation:

Given the points

  • (0, -6)
  • (3, -2)

The slope between the points (0, -6) and (3, -2) will be:

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(0,\:-6\right),\:\left(x_2,\:y_2\right)=\left(3,\:-2\right)

m=\frac{-2-\left(-6\right)}{3-0}

m=\frac{4}{3}

Therefore, the slope between the points (0, -6) and (3, -2) will be:

  • m=\frac{4}{3}

What is the approximate value of x in the diagram below? (Hint: You will need
Delicious77 [7]

Answer:

B. 39.59

Step-by-step explanation:

So 43 degrees, you know the length of the opposite side (27) and the angle (43 degrees), the only unknown is the hypotenuse. So you're looking for a trigonometric ratio that uses the angle (all of them do, except technically the inverse don't), the opposite side, and the hypotenuse. Sine is defined as \frac{opposite}{hypotenuse}. So let's plug in known values:

sin(43) = \frac{27}{x}

Multiply both sides by x

sin(43) * x = 27

divide both sides by sin(43)

x=\frac{27}{sin(43)}

Normally I would use a calculator, but in this case I'll use the approximation given in the problem of 0.682

x=\frac{27}{0.682}

simplify the fraction

x\approx39.59
