Answer:
-3
Step-by-step explanation:
g(1) = -3x² + x - 1
= -3() + 1 -1
= -3(1) + 1 - 1
= -3 +1 -1
g(1) = -3
Just put the 1 everywhere you see an x.

1) Using your compass, draw a circle and label the center O.
2) Using your straightedge, draw a diameter of the circle, labeling the endpoints A and B.
3) Construct the perpendicular bisector of the diameter.
4) Label the points where the bisector intersects the circle as C and D.
Answer:
The correct option is D) 140°
Step-by-step explanation:
Consider the provided figure.
When two parallel lines intersect by a transverse, then the corresponding angles are equal in measure.
Here the corresponding angles are:
m∠1 = m∠5 and m∠2 = m∠6
m∠3 = m∠7 and m∠4 = m∠8
We need to find the measure of angle 5. It is given that m∠1 = 140°
From the above we know that m∠1 = m∠5, thus
m∠5 = 140°
Hence, the correct option is D) 140°
Answer:
PC = 14.42 cm
Step-by-step explanation:
If a tangent and secant are drawn from a point outside a circle, then the product of the lengths of the segments of the secant is equal to the square of the length of the tangent.
PC² = PB × BD
PC² = 4 × 52
PC² = 208
PC =
PC = 14.42 cm
