Answer:
The area of the triangle is 21 ft (640.08 centimeters)
The area of the rectangle is 120 ft (3657.6 centimeters)
The area of the whole figure is 141 ft (4297.68 centimeters)
Step-by-step explanation:
The area of a triangle is:
b is the base and h is the height.
Plug in what you have
multiply 6 by 7
divide 42 by 2
Now you have to find the area of the rectangle
The area of a rectangle is:
A = bh
Plug in what you have
A = (10)(12)
A = 120
Now add both areas together to get the area of the whole figure
120 + 21 = 141

Answer:
475.
Step-by-step explanation:
We have been given that for a normal distribution with μ=500 and σ=100. We are asked to find the minimum score that is necessary to be in the top 60% of the distribution.
We will use z-score formula and normal distribution table to solve our given problem.
Top 60% means greater than 40%.
Let us find z-score corresponding to normal score to 40% or 0.40.
Using normal distribution table, we got a z-score of .
Upon substituting our given values in z-score formula, we will get:
Therefore, the minimum score necessary to be in the top 60% of the distribution is 475.
Answer:
f(x) = (x +4)(x -1)(x -2)²
Step-by-step explanation:
The given points are all x-intercepts of the function. As such, each corresponds to a factor of the function. The x-intercept x=p corresponds to factor (x-p), for example.
Here, the x-intercept (2, 0) is repeated. It is said to have "multiplicity 2". That multiplicity value means the factor will have an exponent of 2 in the factored form of the function:
f(x) = (x -(-4))(x -2)(x -1)(x -2)
f(x) = (x +4)(x -1)(x -2)²

<em>Additional comment</em>
When an x-intercept has even multiplicity, the graph will touch the axis there, but will not cross.
