The first term of an AP can be defined as T1 i.e. n=1. According to the given equation,. T1=a=2(1)+9=11.
Answer:
Yes, the expressions are equivalent.
Step-by-step explanation:
Notice that -2 is defined as in additive inverse of 2, that is, 2 + -2 = 0.
and substracting 2 from 2 is also equal to zero, that is, 2 - 2 = 0.
Thus 2-2 = 2+ -2, implying -2 = + -2. Consequently, -5 + -2 = -5 -2
Answer:
i'd say at least 2 waffle irons on the floor
Step-by-step explanation:
Okay. So, one temperature is positive and the other one is negative. Let’s find the absolute value (distance from 0) for both numbers. -21 is 21 units away from 0 and 6 is 6 units away from 0. 21 + 6 = 27. The difference of temperature from 8 AM to 9 AM is 27 degrees.
Answer:
x^2 +y^2 -40x -24y -81 =0
Step-by-step explanation:
We can write the equation of a circle in the form
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
Assuming that Pamela's cabin is the center
( x-20)^2 + (y- 12)^2 = 25^2
We want to get to general form
x^2 + y^2 + Dx + Ey + F = 0,
Distributing
x^2 -40x +400 + y^2 -24y +144 = 625
x^2 +y^2 -40x -24y +544 -625 =0
x^2 +y^2 -40x -24y -81 =0
