First notice that f(x) is negative, so entire graph will be below x-axis.
Next find domain by setting what is inside sqrt greater than 0.
You can't take sqrt of neg number.
Finally plot some points, start at x = 1, y=0.
Then try x = 0, y = -1.
x = -3, y = -2.
Connect the points, done.
Answer:
<em>From left to right: 54 deg, 51 deg, 47 deg</em>
Step-by-step explanation:
From the bottom right triangle:
105 + 28 + x = 180
x + 133 = 180
x = 47
The lower right triangle has angles measuring 28, 105 and 47.
The lower unknown angle of the upper right triangle is vertical to the 47 deg angle, so it also measures 47 deg.
Now we calculate the upper unknown angle of the upper triangle.
82 + 47 + y = 180
y + 129 = 180
y = 51
One angle forms a linear pair with the 105-deg angle. It measures
180 - 105 = 75.
The large left triangle has angles 75 deg, 51 deg, and the unkown angle at the left.
z + 51 + 75 = 180
z + 126 = 180
z = 54
Answer:
11.02*3= 33.06
3.99*5= 19.95
33.06+19.95= 53.01

Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%
Hope it helps:-)
Answer= 3
-9= 6(5) +c
-9= 30 + c
Bring 30 to the other side
-39= c
Y= 6(7) -39
Y=3
