Recall the logarithm rules :
a^y = x is the same as log_a x = y
In this case,
a = 18
y = r - 10
x = 93
So,
18^ (r-10) = 93
is the same as
log_18 93 = r - 10
Solve for r to get :
10 + log_18 93 = r
Answer:
A) c
B) d
Step-by-step explanation:
Answer:
Option D, x = 4
Step-by-step explanation:
Option A: y = 4 doesn't work because that line would be horizontal
Option B: y = 4x doesn't work because that would be diagnol
Option C: x = -4 doesn't work because that would a vertical line at -4
<em>Option D: x = 4 works because that would a vertical line at 4</em>
<em />
Answer: Option D, x = 4
Answer:
280 m
Step-by-step explanation:
a² + b² = c²
450² + b² = 530²
202,500 + b² = 280,900
280,900 - 202,500 = 78,400
√78,400 = 280
Answer:
Step-by-step explanation:
We want to express 3⅓ as a percentage.
Let us first of all rewrite 3⅓ as decimals to obtain:
To express this as a percentage, we multiply by 100%
This multiplies to give us:
