Answer:21
Step-by-step explanation:
F(x)=4x-8
f(x)=y=4x-8
f^-1(x)=?
x=4y-8
x+8=4y
f^-1(x)=y=1/4x+2
Answer:
True
Step-by-step explanation:
The volume of an object is the amount of matter the shape can hold, so finding how much water the tank can hold is finding the volume of the tank.
Have a great day! Hope this helps!
Answer:
A
Step-by-step explanation:
Answer:
Approximately 360.3
Step-by-step explanation:
△ABC, AB = BC and CH is an altitude.
Note in isosceles triangle the two base angle are equal.
And two sides are equal.
CH = 84 cm and m∠HBC = m∠BAC +m∠BCH
So yhe base angle = 50°
The length of tthe hypotenuse , lets cal it x
Sin 50 = 84/x
X = 84/sin 50
109.65 = x
For the The base
109.65²-84²=b²/4
141 = b
Perimeter = 2*109.65 + 141
Perimeter = 360.3
Approximately 360
