Answer:
Step-by-step explanation:
The foci are horizontally aligned.
horizontal ellipse:
(x-h)²/a² + (y-k)²/b² = 1
center (h,k)
vertices (h±a,k)
length of minor axis = 2b
foci (h±c,k), c² = a²-b²
Apply your data and solve for h, k, a, and b.
foci (±3√19, 6)
h = 0
k = 6
Length of minor axis = 2b = 10
b = 5
foci (h±3√19, 6)
c = 3√19
c³ = a² - b²
171 = a² - 25
a² = 196
x²/196 + (y-6)²/25 = 1
Answer:
40
Step-by-step explanation:
-3 2
-15 - 2 = -17
1 5
-1 - 25 = -26
5<em> </em> -1
-25 - (-1) = - 24
1 <em> -5</em>
2 - <em>15</em> = -13
<em>-3</em> 2
area = |-17 - 26 - 24 - 13|/2 = |-80|/2 = 80/2 = 40
Answer: 40
Using a system of equations, it is found that the equation that could be used to find the value of b is given by:
3×4−8=b
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
Fatima has 3 packs of batteries. Each pack contains 4 batteries, hence:
b = 3 x 4
She gives her brother 8 batteries to put in his toy robot, hence:
b = 3 x 4 - 8
Which means that the first expression is correct.
