Answer:
The solution is:
Step-by-step explanation:
The first step to solve this equation is placing everything with the exponential to one side of the equality, and everything without the exponential to the other side. So
To find x, we have to apply log to both sides of the equality.
We also have that:
So
Its A
7x+7= 112
7x= 112-7
7x=105
x=105/7
x=15
To find y
180-112=68
68/4 =17
x= 15 y=17
Answer:
A.The prism sliced by a plane parallel to the base will take the shape of the base.
D. The prism sliced by a plane perpendicular to the base will take the shape of the side face.
Step-by-step explanation:
A slice is a section of a plane that consists of all points where the plane meets the figure.In a right rectangular prism, the opposite faces are parallel, this means that they do not meet.Any two adjacent faces in a right rectangular prism are perpendicular, to mean one plane will contain a line that is perpendicular to the other plane.If the slice is done by a plane parallel to one face of the prism, the formed slice is a rectangular face identical to the parallel face like in option A. If the slice is done by a plane perpendicular to the base, the slice formed is a rectangular region,with a height similar to that of the prism and a shape of the side face.
Answer:
20
Step-by-step explanation:
x^2+18x-160
If you put this into your calculator or desmos, you will get a parabola. You want to know the value of x when y=600. You can look at the table for the graph or scan to where y = 600. The value of x is 20 at that point.
To check you can plug 20 in for x. When you do that, y = 600.
