Answer:
Step-by-step explanation:
The circumference of a circle = 2*pi * r
so 16 pi yards = 2 * pi * r
Divide both sides by 2
16 pi/2 = 2*pi * r /2
8*pi = pi * r
Divide both sides by pi
8 * pi / pi = pi * r / pi
r = 8
====================
Surface Area = 4 pi * r^2
r = 8
Surface Area = 4 * pi * 64
Surface Area = 256 * pi
Answer:
Step-by-step explanation:
A. 2x+3y+z
X = -2
Y= -3
Z= 5
2(-2)+3(-3)+5
-4-9+5
=8
B. X-Y
-2–3
-2+3
=1
C. 2(x+y/z)
2(-2-3/5)
2(-1)
=-2
D. 3x^2-2x+1
3(-2)^2-2(-2)+1
3(4)+4+1
=17
E.3y(x+x^2-y)
3(-3)(-2+-2^2-(-3))
-9(1)
=-9
F.-z^2(1-2x)/y-x
5^2(1-2(-2)/-3–2
25(5/5)
25(1)
=25

Answer:
1
Step-by-step explanation:
We are finding the discriminant of the function
It needs to be written in the form ax^2 +bx+c =0
2x^2 +3x = -1
Add 1 to each side
2x^2 +3x+1 = -1+1
2x^2 +3x+1 = -0
b^2 -4ac
a=2 b=3 and c = 1
3^2 - 4(2)(1)
9 - 8

Answer: (i think there was supposed to be a photo attached but ???)
-1.05
Step-by-step explanation:
1.5(-3.2 + 2.5)
1.5 x -3.2 = -4.8
1.5 x 2.5 = 3.75
(-4.8 + 3.75)
<u>-1.05</u>
