Answer:
The y intercept for the equation is (0,-7)
The surface area is
A1=7.5*1.5*2=22.5 ft2 top and bottom view
A2=3*1.5*2=9 ft2 laterals view
A3=(7.5*1.5+2.5*1.5)*2=30 ft2 front and rear view
At=22.5+9+30=61.5 ft2
the answer is 61.5 ft2
Using the given roots, it is found that on the interval , the function is positive.
The function is:
The zeroes are:
Between two zeroes, the function has the same sign, hence, to find the sign on the interval , we find the <u>numeric value of the function of a value of x on the interval</u>, for example f(0), for x = 0.
Then:
Since f(0) is positive, the function is positive on the interval .
A similar problem, in which it is desired to find the sign of the function, is given at brainly.com/question/4787253
I think the answer would be 40 questions I don't know if this is actually correct tho
