Answer:

45

Step-by-step explanation:

Replace everything in the equation that has a x to -3:

f(-3)=3(-3)^2-4(-3)+6

Square the -3:

f(-3)=3(9)-4(-3)+6

Multiply/Distribute

f(-3)=27+12+6

Add:

f(-3)=45

Hope this helps!

Answer:

f(x) = 45

Step-by-step explanation:

f (x) = 3x^2 − 4x + 6 find f (−3)

Replace the variable x with −3 in the expression.

f (−3) = 3(−3)^2 − 4 ⋅ −3 + 6

Simplify 3(−3)^2 − 4 ⋅ −3 + 6

Remove parentheses.

3(−3)^2 − 4 ⋅ −3 + 6

Raise −3 to the power of 2.

3 ⋅ 9 − 4 ⋅ −3 + 6

Multiply 3 by 9.

27 − 4 ⋅ −3 + 6

Multiply −4 by −3.

27 + 12 + 6

Simplify by adding numbers.

Add 27 and 12.

39 + 6

Add 39 and 6.

45

Find the rate of change of the following table.
Serjik [45]

Answer:

\frac{1}{3}

Step-by-step explanation:

The rate of change is measured by the slope of the line in this linear table.

Calculate the slope m using the slope formula

m = \frac{y_{3}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (3, 2) ← 2 ordered pairs from the table

m = \frac{2-0}{3+3} = \frac{2}{6} = \frac{1}{3} ← rate of change

Quadrilateral BCDE is inscribed in circle A. The measure of ⏜ is 73°. The measure of ⏜ is 53° and the measure of ⏜ is 102°.
Vesna [10]

Answer:

117

Step-by-step explanation:

Angle BCD intercepted arc is Arc DEB.

We know DE measure but we need to find EB measure.

Since a circle circumference add up to 360, we can add all of the known arcs up to 360 to find the missing arc.

73 + 53 + 102 + x = 360

126 + 102 + x = 360

228 + x = 360

x = 132

So arc EB measure 132.

Arc eb and de.

132+102=234.

Angle BCD is inscribed angle of Arc DEB, so that means angle BCD is half of Arc DEB.

\frac{234}{2}  = 117
