Answer:
A = -49,152
Step-by-step explanation:
The sequence -3, -12, -48, -192 have a geometric Progression.
How did I know that?
The common ratio is gotten by diving the preceding value by a previous one. Such that:
r : -12 / -3 = 4
r : -48 / -12 = 4
Which ever one you pick, gives thesame commonn ration "r" as 4.
Lets proceed.
Geometric Progression (GP) is defined as:
GP: ar^n-1
Where "a" is the first term -3
r is the common ration = 4
n is the number of term = 8th
To solve for the 8th term!
= ar^ 8-1
= ar^7
= -3 * 4 ^ 7
= -3 * 16384
= -49152
Enjoy! Maths is fun!
6x + 5 = 5x + 8 + 2x
6x + 5 = 7x + 8
-5 -5
6x = 7x + 3
-7x -7x
-1x = 3
/-1 /-1
x = -3
Answer:
<em><u>C</u></em>
Step-by-step explanation:
if h<28
- its area= 28×28 = 784, but it is greater than 15 sq inches
- Its volume = 28×28×28 = 21952, but it is greater than 285 cubic inches
hence h must be less than 28 (h<28)
And not greater than √15 ( h<√15)
Thanx
A linear function contains no exponents and is straight. Any function with an exponent is not linear. x^2 is not a linear function; it is a parabola (a curve).
Hope this helps!!
