Answer:
Step-by-step explanation:
A quadratic function is a function in which the highest power of the unknown variable is 2.
Formally, a quadratic function is defined as a function of the form:
From the given options, only B and D has the highest power as 2. Therefore, the equations that represent quadratic functions are:
Answer:
b.
Step-by-step explanation:I think so
Let's go shape by shape!
The area of a rectangle can be calculated as follows:
where L = length and W = width
The area of a trapezoid can be calculated as follows:
where b1 and b2 = lengths of the base and H = height of the shape
The area of a parallelogram can be calculated as follows:
where B = length of the base and H = height of the shape
1/4
probability of getting a tail or a head is 50% or 1/2
If you want a tail then a head, it’s 1/2 *1/2 =1/4
Answer:
55 meters squared
Step-by-step explanation:
SA = sum of all the areas of the sides
The pyramid has four faces, which we have to add together:
SA = 3(long face area) + base area
Area of a triangle = 1/2 base * height
Area of the base = 1/2 * 3.5 * 4 = 7 meters squared
Area of a long face = 1/2 * 8 * 4 = 16 meters squared
Coming back to our surface area formula, we can plug those areas in:
SA = 3(long face area) + base area
= 3(16) + 7 = <u>55 meters squared</u>
