The values would be F(x)=-8
Answer:
117 cm²
Step-by-step explanation:
area of rectangle = 13 * 7 = 91cm²
area of upper one right angle triangle= 1/2 * 6.5 * 4 =13 cm²
area of both triangles = 13 cm² * 2 = 26 cm²
Total area = 91cm² + 26 cm²
--> 117 cm²

Generally the equation for Probability of Choosing a Girl is mathematically given by



Answer:
The measures of ∠BOC is 25.4° and that of ∠AOB is 15.8°.
Step-by-step explanation:
Given that,
∠AOC = 31°
∠BOC = 2x+10
∠AOB = 4x-15
As we can seen from the figure that,
∠AOC = ∠AOB + ∠BOC
Put all the values,
31 = 4x-15+2x+10
31 = 6x-15
31+15 = 6x
46 = 6x
x = 7.7
∠BOC = 2(7.7)+10 = 25.4°
∠AOB = 4(7.7)-15 = 15.8°
So, the measures of ∠BOC is 25.4° and that of ∠AOB is 15.8°.
The total number of common tangents that can be drawn to the circles is 2.
<h3>What is a tangent?</h3>
A tangent serves as line that touches the circle at a single point whereby the point where tangent meets the circle is the tangency.
A tangent to a circle can be described as the straight line that touches the circle at only one point.
Therefore, from the definition, The total number of common tangents that can be drawn to the circles is 2.
