Answer:
3 ×-2 - (2×1) + 2
-6 - 2 + 2

Answer:
Step-by-step explanation:
A parabola has the following format:
If a is positive, it's minium value is:
In which
Factoring:
, in which are the intercepts.
In this question:
So
Suppose a = 1, we have:
The minimum value will be:
We want this minimum value to be -4, which is 4 times the current minimum value, so we need to multiply a by 4. Then
And the parabola is:
The answer is 2(3)(5^2) 150 is not a prime number
A=l√[(w/2)²+h²+w]+w√[(l/2)²+h²]
where
l is base length
w base width
h is height
given that the slant side of our pyramid is 856.1 ft with square base of 145 ft, the height of the pyramid will be found by Pythagorean theorem.
c²=a²+b²
hence:
856.1²=a²+72.5²
a=853.025 ft
The Lateral area is therefore going to be:
A=145√[(145/2)²+856.025²+145]+145√[(145/2)²+856.025²]
A=249,136.0025 ft²
