Answer:
y =
x - 1
Step-by-step explanation:
Do rise over run to find the slope, and this gets you 1/2
The y-intercept is at (0, -1) so put -1 in the equation
The correct answer for the question that is being presented above is this one: "B. -385." Evaluate the summation of negative 5 n minus 1, from n equals 3 to 12 equals B. -385
-5n - 1 where n = 3 to 12.
n = 3 = -16
n = 4 = -21
n = 5 = -26
n = 6 = -31
n = 7 = -36
n = 8 = -41
n = 9 = -46
n = 10 = -51
n =11 = -56
n = 12 = -61
Total = B. -385
Answer:
D. x = log8 24
Step-by-step explanation:
we have this function
8^x = 24
Now we have to understand how the logarithm works.
we use the logarithm to know how much we have to raise a number to reach a result that we already know.
these two equations represent the same
a ^ b = c
log a c = b
8^x = 24
8 = a
x = b
c = 24
log a c = b
log 8 24 = x
option d.
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
• tanx = 
• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Consider the left side

=
- 
= 1 - cos²x
= sin²x = right side ⇒ verified
