Answer:
The answer to your question is: d) 0.46x10^-4
Step-by-step explanation:
(1.15x10⁻⁷) / (2.5x10⁻³)
First, divide 1.15 by 2.5 1.15 / 2.5 = 0.46
Second, subtract the power -7 - (-3) = -7 + 3 = -4
Finally, express the number 0.46 x 10⁻⁴
a) 4.6x10^-10
b) 0.46x10^-3
c) 4.6x10^-3
d) 0.46x10^-4
Answer:
The answer is 2
Step-by-step explanation:
Let the number be x
10 - (3 + x) = 5
10 - 3 -x = 5
7 - x = 5
x = 7-5
x = 2
Answer! :
y = -2x + 5
Step by Step! :
slope intercept form:
y = mx + b
m being slope, b being the y intercept.
To find the slope, use this equation:
y^2 - y^1 / x^2 - x^1
Plug in your points.
(-1) - (7) / (3) - (-1)
-8 / 4
-2 is your slope! (y = -2x + b)
To solve for b, plug in any one of your points and solve for b. Let's use (3, -1)
-1 = -2(3) + b
-1 = -6 + b
5 = b
Your new equation is...
y = -2x + 5

The applicable rules of logarithms are ...
log(ab) = log(a) +log(b)
log(a/b) = log(a) -log(b)
log(a^b) = b·log(a)
