Mathematics again 60+ points as I’m legit promising you fam.

see explanation

Step-by-step explanation:

(a)

The diameter is a line connecting 2 points on the circle and passes through the centre, thus

GF is the diameter

(b)

A radius is a segment joining the centre to a point on the circle, thus

EG, EF and EH are radii of the circle

(c)

A chord is a segment joining 2 points on the circle, thus

JI is a chord

(d)

EH is one half the diameter, thus

GF = 8 units, hence EH = 8 ÷ 2 = 4 units

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
