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
Answer:
the ordered pairs are (-1,3/4), (0,3), (1,12), and (2,48)
an exponential function looks like this:
y=ab^x
substitute the x and y values
3/4=ab^(-1)
3/4=a/b
3=ab^0
3=a*1
3=a, so b=4
y=ab^x
y=3(4^x) is the equation that you want
if x=-1, then y=3/4
if x=0, then y=3
if x=1, then y=12
if x=2, then y=3*4^2=3*16=48
X=3i,-3i ;) used calculator to check
