Answer:
The correct answer is true. A plane formation conditions are: 1) At least three non-collinear points. 2) At least one point and a straight line such that the point should not lie on the straight line. This is the criteria for plane formation

Answer:
f ( - 1 ) = 5
Step-by-step explanation:
Step 1:
f ( x ) = - 2x + 3 Function
Step 2:
f ( - 1 ) = - 2 ( - 1 ) + 3 Input x value
Step 3:
f ( - 1 ) = 2 + 3 Multiply
Answer:
f ( - 1 ) = 5 Combine Like Terms

Answer:
C
Step-by-step explanation:
Remark
The formula that relates tangents and secants using the information given is
The distance from the external point to the point of tangencyo^2 = The external point of secant to the circumfrance of the circle * the other intersect point of the secant.
The algebra is much simpler.
y^2 = 27 ( 27 + x)
Givens
y = 45
27 is the distance from the external point to the circle
27 + x is the entire length of the secant.
Solution
45^2 = 27(27 + x) Remove the brackets
2025 = 729 + 27x Subtract 729 from both sides
2025 - 729 = 27x
1296 = 27x Divide by 27
1286/27 = x
x = 48
Area of rectangle = l × b = 16 × 8 = 128cm²
Area of 1 triangle = ½ × b × h = ½ × 2 × 2 = 2cm²
Area of 4 triangle = 2cm² × 4 = 8cm²
Area of shaded region
= Area of rectangle - Area of 4 triangle
= 128cm² - 8cm²
= 120cm²
When n increases by 1, a_n increases by 7—the multiplier of n in the explicit formula.
