Step-by-step explanation:
Answer:
120 cm²
Step-by-step explanation:
From the question;
- Length is 12 cm
- Width is 10 cm
We are required to determine the area of the cross section;
- Note that the cross section is the plane of a solid that remains constant through the solid.
- In this case, the cross section is a rectangle whose dimensions are 12 cm by 10 cm.
But Area of a rectangle = Length × Width
Therefore;
Area of cross section = 12 cm × 10 cm
= 120 cm²
Thus, area of the cross section is 120 cm²
Answer:
Step-by-step explanation:
Two sides are equal. so It is an isosceles triangle.
The angles opposite to equal sides are equal
x + 55 + 55 = 180 {Sum of all the angles of triangle is 180}
x + 110 = 180
x = 180 - 110
x = 70
Function B increases at a faster rate. The rate of change for A is 1. The rate of change for B is 1.5.
In order to find the rate of change for each so that we can compare, we need to use the following formula.
Change = (y2 - y1)/(x2 - x1)
In which (x1, y1) is the original point (x = 2) and (x2, y2) is the second point (x = 3). So, let's use the equation for each set of points.
FUNCTION A
Change = (y2 - y1)/(x2 - x1)
Change = (0 - -1)/(3 - 2)
Change = 1/1
Change = 1
FUNCTION B
Change = (y2 - y1)/(x2 - x1)
Change = (0 - -1.5)/(3-2)
Change = 1.5/1
Change = 1.5
