The common difference can be found from
The first term of the sequence can be found from either of the given terms.
The sum of 40 terms is
The sum of the first 40 terms is 3800.
Step-by-step explanation:
h(x) is positive when h(x) is greater than 0.
When h(x) = 0, 2x + 10 = 0, x = -5
Since this is a straight line graph and the gradient is positive, the interval is (-5,∞).
Step-by-step explanation:
The area A of the tire in contact is 7"×5" = 35 sq inches and we know that each tire has a pressure of 30 psi so the weight of the car in tons is
For this case we have that by definition, an equation of the line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes, then we find the slope:
Then, the equation is of the form:
We substitute a point and find b:
Finally we have:
y = x-4
Answer:
Option B
Angle Angle Side. The side is given to you and use the interior angle to find one angle, and the the reflexive property to find the other.
