Answer: X= -9
Step-by-step explanation: solve for x by simplifying both sides of the equation then isolating the variable
Answer:
5.503%
Step-by-step explanation:
Assuming that the interest earned is of compounding nature(annual compounding):
#where t=time, A=Total earned, P=Principal.
#We substitute our known values in the equation to get:
![11349=7800(1+I)^7\\\\1.455=(1+i)^7\\\\(1+i)=1.455^{\frac{1}{7}}=1.05503\\\\i=1.05503-1\\\\i=0.05503](https://tex.z-dn.net/?f=11349%3D7800%281%2BI%29%5E7%5C%5C%5C%5C1.455%3D%281%2Bi%29%5E7%5C%5C%5C%5C%281%2Bi%29%3D1.455%5E%7B%5Cfrac%7B1%7D%7B7%7D%7D%3D1.05503%5C%5C%5C%5Ci%3D1.05503-1%5C%5C%5C%5Ci%3D0.05503)
Hence the annual rate of interest is 5.503%
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -
x ← is in slope- intercept form
with slope m = - ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
The plot of a function <em>f(x)</em> is symmetric across the <em>y</em>-axis if it is even, meaning <em>f(-x)</em> = <em>f(x)</em> for all <em>x</em> in the function's domain.
The answer is then A because
(-<em>x</em>)² = (-1)² <em>x</em>² = <em>x</em>²
|-<em>x</em>| = |-1| |<em>x</em>| = |<em>x</em>|
cos(-<em>x</em>) = cos(<em>x</em>)
The answer is <u>not</u>
• B because sin(-<em>x</em>) = -sin(<em>x</em>) and (-<em>x</em>)³ = (-1)³ <em>x</em>³ = -<em>x</em>³
• C because -<em>x</em> ≠ <em>x</em> and again because of <em>x</em>³
• D because 1/(-<em>x</em>) = -1/<em>x</em> and again because of sin(<em>x</em>)
