Answer:
1.25cm
Step-by-step explanation:
<em>Complete question:</em>
The prism has a volume of 35 cm cubed workout h, the height of the triangular cross section
<em>length=7cm</em>
<em>width = 4cm</em>
<em></em>
The volume of the prism is expressed as;
Volume = Base Area * Height
Given
Volume of the prism = 35cm^3
Base Area = length * width
Base Area = 7cm * 4cm
Base Area = 28cm^2
Substitute the given values into the formula
35 = 28* Height
Cross multiply
35 = 28 * Height
35 = 28 Height
Height = 35/28
Height = 1.25cm
Hence the height of the triangular cross section is 1.25cm
we know that
<u>The domain</u> of the function graphed is the interval-------> [3,∞)
that means
All real numbers greater than or equal to 
<u>The range</u> of the function graphed is the interval --------> [1,∞)
that means
All real numbers greater than or equal to 
therefore
the answer is the option
Think you gotta add them all up them divide by how many numbers their are
6 acts as the base. 15 acts as the height, because it extends from the base to meet vertex opposite the base at a 90° angle.
General formula for triangle area
a = 1/2 × b × h
plug in the numbers
a = 1/2 × 6 × 15
a = 90/2
a = 45
The area of the triangle is 45 units²
A = 3.14r^2
A = 3.14(12)^2
A = 3.14(144)
A = 452.39
