This is what I got. The standard equation for a hyperbola with a horizontal tranverse axis is - = 1. The center is at (h,k). The distance between the vertices is a 2a. The distance between the foci is 2c. I hope that helped :\
Let
x----------> length of the base
y----------> height
we know that
[the area of triangle]=[length of the base]*[height]/2
x=2y
A=225 km²
225=x*y/2---------> 225=(2y)*y/2-----> y²=225--------> y=15 km
x=2y--------> x=2*15------> x=30 km
the answer is
the height is 15 km
Let the measure of the unknown angle is x °
Supplementary angles sum up to 180°. So the supplementary angle of x° will be (180 - x)°
According to the given data, measure of x is 40° less than 3 times the measure of its supplementary angle (180 - x). So we can set up the equation for this scenario as:

So the degree measure of the required angle is 125°.
Answer:
d. 194481
Step-by-step explanation:
We solve this question using exponential growth rate formula
This is given as:
y = a(1 + r) ^t
Where y = Amount after time t
a = Initial amount = 160000
r = growth or increase rate = 5% = 0.05
t = time in years = 4
y = 160000(1 + 0.05)⁴
y = 160000(1.05)⁴
y = 194481
Therefore, the number of cows needed after 4 years to fulfill the requirement of the milk is 194481
x + 9 = -44
1. Subtract 9 to both sides
x = -53
