Martinez puts $500 in his piggy bank. He adds $40 a month. How much money willMartinez have at the end of two years?
Answers
Answer: $1460
Step-by-step explanation:
He will add $40 for 24 months since there are 24 months in two years. 40 x 24 = 960 so you should add 960 and the original amount of 500. This ends up with $1460
Answer:
$1460
Step-by-step explanation:
So he already has $500 in his piggy.
There are 24 months in 2 years.
So, we would multiply 24 by $40
That would be $960
Add the $500 to $960.
$1460

What is cube?
In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices

Answer:
x = 5 5/6
Step-by-step explanation:
The goal in algebra is always to isolate the variable, so that its value can be determined.
Step 1: Subtract 1/6
x = 5 5/6
Step 2: Check
5 5/6 + 1/6 = 6
6 = 6 ✔
Step 3: Answer
x = 5 5/6

Step-by-step explanation:
The vertices and foci are on the x-axis. Thus, the equation for the hyperbola will have the form x2a2−y2b2=1 x 2 a 2 − y 2 b 2 = 1 . The vertices are (±6,0) ( ± 6 , 0 ) , so a=6 a = 6 and a2=36 a 2 = 36 . The foci are (±2√10,0) ( ± 2 10 , 0 ) , so c=2√10 c = 2 10 and c2=40 c 2 = 40 .

x 2 + y 2 - 10x - 8y + 1 = 0.
(x^2-10x+25-25) +(y^2-8y+16-16) + 1 = 0
(x-5)^2 -25 + (y-4)^2 -16 + 1 = 0
(x-5)^2+(y-4)^2 = 40
center (5,4); radius = sqrt(40)

8x^2+ 6y 2 - 32x + 24y + 8 = 0.
8(x^2-4x+4-4) +6(y^2+4y+4-4) +8=0
8(x-2)^2 -32 + 6(y+2)^2 -24 + 8 = 0
8(x-2)^2+6(y+2)^2 = 48
divide throughout by 48
(x-2)^2 /6 + (y+2)^2 /8 = 1
Ellipse with center (2,-2)
a=sqrt(6)
b=sqrt(8)
c^2= 8-6 = 2
c= sqrt(2)
eccentricity = c/a = sqrt(2)/sqrt(6)
3)
y=x^2-12x+36-36
y=(x-6)^2 - 36
Vertex is (6,-36)
(x-h)^2=4p(y-k)
(x-6)^2 = 4p(y+36)
4p=1
p=1/4
focus : (h, k+p) = (6, -36+1/4) = (6, -143/4)
4)
focus lies on a vertical line, so the major axis is parallel to the y-axis
(x-h)^2/a^2 +(y-b)^2/b^2 = 1
h=-2
k=0
(x+2)^2/a^2+y^2/b^2 = 1
2b=20
b=10
b^2=100
(x+2)^2/a^2 +y^2/100 = 1
e=c/a
c/a = 4/5
c=(4/5) a
c^2 = 16/25 a^2
c^2 = b^2-a^2
(16/25) a^2 = 100 - a^2
a^2(16/25+1) = 100
41a^2/25 = 100
a^2=2500/41
a= sqrt(2500/41)
(x+2)^2/a^2 +y^2/100 = 1
(x+2)^2 /[2500/41] + y^2/100 = 1
