a. equate yourequation to zero then yourx intercepts are (-6;0) and (4;0)
b. to find the y-intercept...let x=0...where there is x put 0 and your answer is -24 therefore the y-intercept is (0;-24)
Answer:
the teacher should be sad. the correct answer is 68 inches is NOT greater than 70 inches, therefore a triangle can't be created
Step-by-step explanation:
in a triangle, 2 sides added together have to be greater than the third side or else the triangle can't be created. therefore, since 31+37=68 inches, and 68<70, the triangle can't be created.
Answer:
see below
Step-by-step explanation:
The angle where chords cross is the average of the intercepted arcs. Here, that is ...
(37° +46°)/2 = (83°)/2 = 41.5°
Angle SUT is 41.5°.
_____
<em>Comment on the error</em>
The measure of an arc cannot be arbitrarily said to be the same as the angle where the chords cross. It will be the same if (a) the chords cross at the circle center, or (b) the opposite intercepted arc has the same measure. Neither of these conditions hold here.
Answer:
97
Step-by-step explanation:
9+7*9=72
9+18+10=37
10+10+7=27
7+9*10=97
Answer:
3.14 square units
Step-by-step explanation:
Circumference of a circle = 2πr
2πr = 6.28
r = 6.28/2π
r = 3.142/π
Area of a circle = πr^2
slot in the value of r
Area of the circle = π( 3.142/π)^2
" = π(9.87/ π^2)
" = 9.87/π
π = 3.14
Area of a circle = 9.867/ (3.14)
" = 3.14 square units
