Answer:
The specific weight is 
Step-by-step explanation:
The question in English
A cone has a lateral area of 255 pi cm^2, an apothem of 17 cm and weighs 900 pi g. It calculates the specific weight of the material of which it is composed
step 1
Find the radius of the cone
we know that
The lateral area of a cone is equal to
we have
substitute the values
Simplify
step 2
Find the height of the cone
Applying the Pythagoras Theorem
substitute the values and solve for h
step 3
Find the volume of the cone
The volume of the cone is equal to
substitute the values
step 4
Find the specific weight
Divide the mass by the volume
i think the answer is c :)
Answer:
x = 10
Step-by-step explanation:
First, distribute:
Next, subtract 
from both sides:
(multiply by 2 to get common denominator, 
)
Next, subtract 
from both sides:
(multiply 
by 2 to get common denominator, 
)
⇒ 
Next, multiply both sides by 10:
FInally, divide both sides by -1:
x = 10
Given:
y-intercept of the graph: (0, 90)
zeros: 5 and 9
The equation that models the function based on the zeros given, is either
y = 90 (x-5) (x-9)
or
y= 2(x-5)(x-9)
try solving for the y-intercept of each function,
y = 90 (0-5) (0-9)
y = 4050
(0, 4050)
y = 2(0-5) (0-9)
y = 90
(0, 90)
therefore, the equation that models the function is y = 2(x-5)(x-9)
