Answer:

63/2 or 31.5

Step-by-step explanation:

we can split this shape into 2, a triangle and a rectangle

A triangle = bh/2 = 7*3*1/2 = 21/2

A rectangle = b*h = 3*7 = 21

21/2 + 21 = 63/2

R = { (x,y): 3x-y=0 }

The condition is 3x=y so that's not going to be any of these things.

R is reflexive if (x,x)∈R for all x. Let's check.

3x - y = 3x - x = 2x ≠ 0 necessarily. NOT REFLEXIVE

R is symmetric if (x,y)∈R → (y,x)∈R. Let's check.

(x,y)∈R so

3x-y = 0

y = 3x

Is (y,x)∈R. That would be true if 3y-x=0

3y - x = 3(3x) - x = 8x ≠ 0 necessarily NOT SYMMETRIC

R is transitive if (x,y)∈R and (y,z)∈R → (x,z)∈R. Let's check.

3x-y = 0 so y=3x

3y-z = 0 so z=3y = 9x

3x - z = 3x - 9x = -6x ≠ 0 necessarily NOT TRANSITIVE

πAnswer:

Therefore, the area of a sector of a circle would be 13.5π square units.

Step-by-step explanation:

Given

$r=9$ mi

Ф = 60°

The area of a sector of a circle is:

A = π r² Ф/360

A = π (9)² 60/360

A = π 81 * 1/6

A = 13.5π square units

Therefore, the area of a sector of a circle would be 13.5π square units.

9. If f(x) = 5x-4 and f(2a) =156 , then what is the value of a?

$f(x) = 5x - 4$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f(2a) = 5(2a) - 4$

$f(2a) = 10a - 4$

$156 = 10a - 4$

$10a - 4 = 156$

Add sides 4

$10a - 4 + 4 = 156 + 4$

$10a = 160$

Divide sides by 10

$\frac{10a}{10} = \frac{160}{10} \\$

$a = 16$
