Answer: top triangle = 10 x 4 = 40cm^2 / 2 = 20cm^2
Rectangle = 10 x 6 = 60cm^2
Right hand triangle = 6 x 4 = 24cm^2 / 2 = 12cm^2
Step-by-step explanation:
For top triangle we do 10 - 6 to get shortest side
Rectangle - ignore 14 and use top 10 cm
Finally triangle on right hand - do 14cm - 10 to get base side. Base side is 4cm.
Formula for area of triangle = b x h / 2
Note: ^2 is just to the power of 2 or squared
I hope u found this answer beneficial.
Have a nice day and Christmas holidays m8 :-)
Answer:
f^-1(x)=³√[(x+7)÷4]
Step-by-step explanation:
f(x)=4x^3-7
y=4x^3-7
interchange 'y' with 'x'
x=4y^3-7
make y the subject
4y^3=x+7
divide by 4 both sides
y^3=(x+7)÷4
multiply by the cube root both sides
³√(y^3)=³√[(x+7)÷4]
y=³√[(x+7)÷4]
f^-1(x)=³√[(x+7)÷4]
