Answer:
b. 2005
Step-by-step explanation:
(apex)
300=150(1.07)^x
1.07^x=2
x=ln 2/ln 1.07
=10.24
1995 plus ten years = 2005

The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,
A = bh / 2
where A is area, b is base and h is the height.
Substituting the known values,
A = (4 inch)(9 inch) / 2 = 18 in²
Multiplying this area by 4 will give us an answer of 72 in².
Then, we also calculate for the area of the square base.
A = s²
where s is the measure of each side of the square.
A = (4 in)² = 16 in²
Finally, we add up the calculated areas.
surface area = 72 in² + 16 in²
<em>surface area = 88 in²</em>
Hence, the surface area of the figure is equal to 88 in².
The answer is seven because if you divide 49 by 7 it equals 7.
Let's solve your equation step-by-step.
x2−6x+10=0
For this equation: a=1, b=-6, c=10
1x2+−6x+10=0
Step 1: Use quadratic formula with a=1, b=-6, c=10.
± 
x = −(−6)± 
x= 6± 
x = 6± 
/ 2
x = 6 ±
