You are a rhombus sometimes although not correctly referred to as a diamond
Answer:
-2497
Step-by-step explanation:
Sn=n/2[2a+(n-1)d]
=22/2[2*-40+(22-1)d]
=11(2*-40+(21*-7)
= -2497
Answer:
42°
Step-by-step explanation:
The interior angles of a triangle always add to 180 degrees.
90+48+x=180
x=180-90-48
=42
x is 42°
Answer:
Step-by-step explanRemember: logax=b⇒ab=x
in which "a" is the base of the log.
log4 (1/16) = 4^-2 = 1/4^2 = 1/16
4 to the power of -2 is equal to 1/16.
To answer this question, the equation in exponential form of "log4 (1/16) = -2" is " 4^-2 " (4 to the power of -2). :D
