Answer:
option a)
y = m(0.5) + 1.8
Step-by-step explanation:
Equation 
<h3>
y = mx + c</h3>
represent the equation of straight line 
here m = gradient of straight line
          c = y-intercept 
First find the gradient of the graph
<h3>
m = y2 - y1 / x2 - x1</h3>
     = 4 - 3 / 4 - 2 
     = 1 / 2
Put the values in the equation of straight line
y =mx + c
4 = 1/2(4) + c
c = 2
y = 1/2x + 2
which is approximately equal to y = 0.5x + 1.8
 
        
             
        
        
        
Answer:
Step-by-step explanation:
You don't specify what you're supposed to do, so I'll make an educated guess.  
Given the sequence f(1) = 4, f(n) = f(n  − 1) + 11, find the first 5 terms:
f(1) = 4
f(2) = f(2 - 1) + 11 = f(1) + 11 = 4 + 11 = 15
f(3) = f(2) + 11 = 15 + 11 = 26
f(4) = f(3) + 11 = 26 + 11 = 37
f(5) = 37 + 11 = 48

Answer:
<h3>Surface Area = 1,256 cm</h3>
<u>Solution:</u>
formula: Surface Area of a Sphere: 4π · r²
Surface area = 4π · r²
SA = 4(3.14) (10)²
SA =  (12.56)(100)
SA = 1,256
