Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- vertices of hyperbola:(±a,0) and (0,±b) if reversed
<h3>given:</h3>
- vertices: (0,±10)
- the hyperbola equation is inversed since the vertices is (0,±10)
- asymptotes:
<h3>let's solve:</h3>
- the asymptotes are in simplest and we know b is ±10
according to the question
therefore we got
note: the equation will be inversed
let's create the equation:
Answer:
y=9
Step-by-step explanation:
4y-7=29
(add 7 to both sides)
4y=36
(divide both sides by 4)
y=9
(a)^2+(b+22)^2=(c+44)^2. Then just solve for the variables
You always want to get y by itself and in the form y = mx + b. So first, subtract 4x from both sides to get -y = -4x +32
You also want to get rid of that negative sign. That’s easy, divide everything by negative 1 to get:
y = 4x - 32
We can see the slope is just 4 and the y intercept is -32. The y-intercept is when x equals zero, you’ll get -32 if you do so. The x-intercept is now when y equals zero. Now solve for x. You get 4x = 32, divide by 4 to get 8
a.) 8
b.) -32
c.) 4
If your ratio is 1 : 50, then for every 1 ft of the model, you have 50 feet of actual church. Thus, if the model is 3.5 ft, then
1 / 50 = 3.5 / x
where x is the actual height of the church. Cross multiply and solve for x.
1 * x = 50 * 3.5
x = 175
Thus, the actual church is 175 ft
