22 ÷ .10
=2.2
22 - 2.2 = 19.80
She had to pay $19.80.
Answer:
f(x)=8-4
Step-by-step explanation:
f(x) = 8 (x+1/4)^2-1/2
f(x) = 8 – (x+1/4)^2-1/16
f(x) = 8 – 2
f(x) = 8 – 4
The depth of diving expressed as signed numbers indicates the magnitude
and direction of Brent and Giselle's displacement in the water.
- The situation expressed as signed number is; <u>-5, -80</u>
Reasons:
The depth Brent decides to go snorkeling = 5 feet below sea level
The depth to which Giselle decides to explore = 80 feet below sea level
Required:
To represent the situation as signed numbers.
Solution:
Taking the sea level as 0, we have;
The depth to which Brent goes = 0 feet - 5 feet = -5 feet
Depth at which Giselle explores = 0 feet - 80 feet = -80 feet
Expressed on the number line, we have;
<u>-∞∣ -80∣ -5∣ 0∣ 5∣ </u>
Therefore;
- The situation expressed as signed numbers is; <u>-5, -80</u>

X^2+y^2 = 16
can be written as
(x-0)^2+(y-0)^2 = 4^2
We see that the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2
where
(h,k) = (0,0) is the center
r = 4 is the radius
The polar form of the equation is simply r = 4. Why is this? Because the radius is fixed to be 4 no matter what happens with theta. As theta goes from 0 to 360, the points generated all form a circle centered at (0,0) with radius 4.
Answer: r = 4
