Answer:
Step-by-step explanation:
<u>Question 7</u>
Angle formed by 2 chords is half of the sum of the intercepted arcs
- x = 1/2(72° + 58°) = 1/2(130°) = 65°
<u>Question 8</u>
Angle formed by 2 secants is half of the difference of the intercepted arcs
- x = 1/2(360° - (130° + 98° + 41°) - 41°) = 1/2(50°) = 25°
Student B would be able to run 1/4 of a mile in one minute.
Answer:
30, assuming it's a right triangle
Step-by-step explanation:
The answer assumes this is a right triangle. Otherwise, it's impossible to answer.
The sum of angles in a triangle is 180deg. As we know 2 of the angles (90deg and 60deg) we need to subtract them from 180deg.
180-90-60 = 30
Answer:
y = -3x^2
Step-by-step explanation:
A quadratic function has a leading coefficient which determines its width. When |a| < 1 the graph is wider. When |a| > 1 the graph is narrower. This means y = -3x^2 is the narrowest graph since 3 is the greatest.
Answer:
x = 5
Step-by-step explanation:
TU is a tangent segment with length 6. RT is a secant segment.
In the circle, the square of the tangent is equal to the product (multiply) of the part of the secant outside the circle and the secant's entire length.
Words don't work well here, do they!
In symbols, (ST)(RT) = (TU)^2
