Answer:
The area of the triangle is of 8 units of area.
Step-by-step explanation:
Answer:
The area of the triangle is of 21 units of area.
Step-by-step explanation:
The area of a triangle with three vertices
is given by the determinant of the following matrix:

In this question:
Vertices (1,0) (5,0) (3,4). So




The area of the triangle is of 8 units of area.
There are 91 in total. Since there are 21 red cars, it would give you 21/91. Around a 23.07% chance.
Answer:

Step-by-step explanation:
Given that,
The area of the base = 13.2 cm²
The height of the pyramid = 13.7 cm
We need to find the volume of this pyramid. The formula can be given by :

Put all the values,

So, the volume of the pyramid is equal to
.
Answer:
The x-axis
Step-by-step explanation:
The graph of the equation x=y2+4 is symmetric with respect to the x-axis.
To test for symmetry with respect to the x-axis we substitute -y in place of y and simplify the equation. If the resulting equation is identical to original one then the function is symmetric with respect to the x-axis;

which is identical to the original equation
