Step-by-step explanation:
wait, I will look my lecture last year
Answer:
A 4/5 × 10 1/2 =8.4
B 2 1/2 × 16/5 =8
C 3 2/3 × 2 1/2 = 330/36 = 9.1666
D 20/3 × 9/10 =6
C IS THE GREATEST because 9.166 is greater than 8.4, 8 and 6
Step-by-step explanation:
1.
a) yes
b) no
c) yes
d) no (not completely sure on this one)
2. same; vary; variability; answers; predictions
Step-by-step explanation:
You have to substitute... 0, 5, & 10, & 3
y = 2x + 3
y = 2(0) + 3
y = 0 + 3
y = 3
(0,3)
y = 2x + 3
y = 2(5) + 3
y = 10 + 3
y = 13
(5,13)
y = 2x + 3
y = 2(10) + 3
y = 20 + 3
y = 23
(10,23)
y = 2x + 3
y = 2(3) + 3
y = 6 + 3
y = 9
(3,9)
Answer:
3/4 of the area of the circle is of
squared units.
Step-by-step explanation:
Equation of a circle:
The equation of a circle has the following format:

In which the center is
and r is the radius.
Area of a circle:
The area of a circle of radius r is given by:

Circle (x+2)² + (y-5)² = 64
Comparing with the standard equation, we have that:

Area of the circle:

What is 3/4 of its area?

3/4 of the area of the circle is of
squared units.
