the equation is y=4x
Answer:
1. 
2. 
Step-by-step explanation:
1. Solution for 1st part.
Given:
Ben shared his post with 2 friends
Each of those friends shares with 3 more every day.
the number of shares triples every day.
From the data given above, we can make the following:

An exponential function is represented by:

where a is the initial value and b is the growth rate.
The exponential function for this case would be:

2. Solution for part 2.
Given:
Carter shared his post with 10 friends.
each share with only 2 people each day.
From the data given above, we can make the following:

An exponential function is represented by:

where a is the initial value and b is the growth rate.
The exponential function for this case would be:

The Answer is :

Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 : a ≠ 0, then
The nature of it's roots can be determined by the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then roots are real and distinct
• If b² - 4ac = 0 then roots are real and equal
• If b² - 4ac < 0 then roots are not real
For x² - 4x + 4 = 0 ← in standard form
with a = 1, b = - 4, c = 4, then
b² - 4ac = (- 4)² - (4 × 1 × 4) = 16 - 16 = 0
Hence roots are real and equal
This can be shown by solving the equation
x² - 4x + 4 = 0
(x - 2)² = 0
(x - 2)(x - 2) = 0, hence
x - 2 = 0 or x - 2 = 0
x = 2 or x = 2 ← roots are real and equal
Detailed Answer:
Diameter = Radius * 2
Radius = Diameter/2
a) 64cm
r = 32 cm
Diameter = 32 * 2 = 64cm
b) 25.2 m
r = 12.6 m
Diameter = 12.6 * 2 = 25.2 m
c) 29.5 in
r = 14 3/4 = 14.75
Diameter = 14.75 * 2 = 29.5 in
d) 64 cm
r = √32 cm^2 = 32 cm
Diameter = 32 * 2 = 64 cm
e) 49.32 ft
r = 24.66 ft
Diameter = 24.66 * 2 = 49.32 ft
