Step-by-step explanation:
Find the equation of the parabola in the form This parabola passes through the point (3,2), so
Thus, the parabola equation is
Now, find the equation of the tangent line.
The equation of the tangent line is
This line intersects x-axis at point (1.5, 0), because
Find the shaded area:
Answer:
6 and 7
Step-by-step explanation:
To do this, we need to look at the two closest numbers that are divisible by 6. These are 36 and 42.
As 37 is between 36 and 42, the quotient must be between 6 and 7
Answer:
<h2>B. 7.1</h2>
Step-by-step explanation:
Given the sample data 2 6 15 9 11 22 1 4 8 19, before we can get the standard deviation, we need to first calculate the mean.
mean = 2 +6 +15 +9 +11 +22 +1 +4 +8 +19/10
mean = 97/10
mean = 9.7
Standard deviation for ungrouped data is expressed using the formula;
<em>Hence the standard deviation of the sample data is 7.1</em>
Answer:
x^2 +2x -5
Step-by-step explanation:
f(x) = 2x+3
g(x) = x^2 -8
f(x)+g(x) = 2x+3+ x^2 -8
Combine like terms
= x^2 +2x -5
