Answer:
x=0.450765 or x=−0.950765
Step-by-step explanation:
14x² + 7x - 6
→ Find the product, sum and factors
Product = -6
Sum = 7
Factors = No factors
→ Since there are no factors utilise the quadratic formula

→ List the values of a, b and c
a = 14
b = 7
c= -6
→ Substitute into the formula

→ Simplify
x=0.450765 or x=−0.950765
Answer:
B
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ 3, 5 ]
From the table of values
f(b) = f(5) = 32
f(a) = f(3) = 8
Hence
average rate of change =
=
= 12
Answer:
B is correct
Step-by-step explanation:
In order to simplify a square root, look at the number inside the square root. See its factors. For this problem, 100*2=200. The square root of 100 is 10, which you would take outside of the square root. This leaves 2 inside the square root, which cannot be further simplified.
Answer: A straight angle
Step-by-step explanation:
90 + 90 = 180
