Answer:
x = - 9, x = 0, x = 7
Step-by-step explanation:
Given
x(x - 7)(x + 9) = 0 ← in standard form
Equate each factor to zero and solve for x
x = 0 ⇒ x = 0
x - 7 = 0 ⇒ x = 7
x + 9 = 0 ⇒ x = - 9
Answer:
reasonable conclusion , representative sample
Step-by-step explanation:
The fraction for 0.21 would be 21/100
Let us say that:<span>
P = present value
F = future value
i = interest rate
n = period
P = F / [ (1 + i ) ^n ]
P = 200000 / [ (1 + 0.011) ^6 ]
P = 187293.65
<span>Therefore the student must put up Php 187,293.65</span></span>
Answer:
15.9 centimeters
Step-by-step explanation:
the information we have is:
Perimeter: ![P=95.4cm](https://tex.z-dn.net/?f=P%3D95.4cm)
Number of sides of the polygon: ![n=6](https://tex.z-dn.net/?f=n%3D6)
since each side has equal length, we can use the following equation to find the measure of one side of the polygon, the equation for perimeter:
![P=nl](https://tex.z-dn.net/?f=P%3Dnl)
where n is the number of sides and
is the length of each side.
So we clear for
and we get:
![l=\frac{P}{n}](https://tex.z-dn.net/?f=l%3D%5Cfrac%7BP%7D%7Bn%7D)
and subtituting the known values:
![l=\frac{95.4cm}{6}\\ l=15.9cm](https://tex.z-dn.net/?f=l%3D%5Cfrac%7B95.4cm%7D%7B6%7D%5C%5C%20l%3D15.9cm)
each side is 15.6 centimeters long
