Answer:
Ques 1:
Let us consider the system of equations,
and
It is known that 'The intersection points of the graphs of the system of equations are the solutions of the system of equations'.
So, after plotting the given graphs, we see that from the first graph,
The only intersection point is (1,1).
Thus, the solution of the system is x= 1 and y= 1.
Ques 2:
We have the functions, f(x)= 2x+1 and g(x)= 2x^2+1.
Plotting the graphs of both the functions is shown by graph 2, we see that,
The intersection points are (0,1) and (1,3)
Hence, the function have equal values only at x= 0 and x= 1 but not at x= 3.
The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.
Step-by-step explanation:
The given is,
A solid clay brick in the shape of a rectangular prism.
A length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches.
The clay weighs 1.055 ounces per cubic
Step:1
Formula for volume of rectangular prism,
...................(1)
Where, w - Width of the rectangular prism
h - Height of rectangular prism
l - Length of rectangular prism
From the given,
w = 3.5 inches
h = 2.25 inches
l = 8 inches
Equation (1) becomes,
Volume, V = 63 cubic inches
Step:2
Weight of brick = Volume of brick × Weight per cubic inch
= 66.465 ounces
Weight of brick = 66.465 ounces
Result:
The weight of solid clay brick is 66.465 ounces, if solid brick with a length of 8 inches, a width of 3.5 inches, and a height of 2.25 inches and the clay weighs 1.055 ounces per cubic inch.
