Answer:

18+12.125π units²

Step-by-step explanation:

The diameter of the semicircle can be found by the use Pythagoras theorem.

Δx²+Δy²=d²

Δx=3--1=4

Δy=3--6=9

d²=4²+9²

d=√(16+81)

Area=πr²/2

=π×(√(16+81)/2)²÷2

=[π×(97)/4]/2

=97π/8

=18+12.125π units²

97π/8 is equivalent to 18+12.125π units²

Jarry is making a strawberry smoothie which measure is greatest the amount of milk cottage cheese or strawberry
Stells [14]

Answer:

Milk

Step-by-step explanation:

The amount of milk, cottage cheese and strawberries used are given in the attached picture.

3/4 cup of milk

2/6 cup cottage cheese

8/12 cup strawberry

Converting the fractions to decimal :

3/4 cup of milk = 0.75

2/6 cup cottage cheese = 0.3333

8/12 cup strawberry = 0.66666

0.75 > 0.6666 > 0.3333

We can conclude that amount of milk is greatest, then strawberry and the least is cottage cheese.

If f(x)= 3x-1 and g(x)=2x-3, for which value of x does g(x)= f(2)
gregori [183]

Answer:

g(4)=f(2)

Step-by-step explanation:

f(2)=3(2)-1

f(2)=6-1

f(2)=5


We then get:

g(x)=f(2)

subsitute 5 for f(2)

g(x)=5

now solve

5=2x-3

add 3

8=2x

divide 2

4=x

so the answer is x=4 or  

g(4)=f(2)
