Answer:
2. domain: {3,4,5,6,7}; range: {2,3,4,5,6}
4. IS a function
Step-by-step explanation:
2. The <em>domain</em> is the list of first numbers of each pair.
The <em>range</em> is the list of second numbers.
4. If each value on the left only has <em>one arrow</em> coming from it, the relation <u>is</u> a function. That is the case here.
__
Contrast that to the problem above (3.). In that one, the number 4 1/2 has two arrows coming from it. That relation is NOT a function.
X intercepts: (37/8,0)
y intercepts: (0,37/9)
Answer:
71 degrees
Step-by-step explanation:
please someone help me with this ASAP especially with the workout!!
From the triangle shown;
YX² = YZ² + XZ² - 2(YZ)(XZ) cos Z
28² = 25² + 23² - 2(25)(23) cos Z
784 = 625 + 529- 1150 cos Z
784 - 1154 = -1150cos Z
-370 = -1150cos Z
cos Z = 370/1150
cos Z = 37/115
cos Z = 0.3217
Z = arccos 0.3217
Z = 71.23
hence the measure of <Z is 71 degrees
The equation of the ellipse ( in the standard form ) :
x² / a² + y²/ b² = 1
a = 6, b = 5 ( from a graph )
