Answer:
hello again
Step-by-step explanation:
Answer:
1.5 cm = .015 meters
3.5 / .015 = 233.33
So, in his scale everything will be 233.33 times smaller.
So, if the building is 180 meters tall, his model will be (180 / 233.33) meters tall, which equals 0.771439592 meters which equals
77.14 centimeters.
Step-by-step explanation:
7. Factor. (x - 2)(4x + 5) = 0 The zeroes are 2 and -5/4. The answer is C.
8. Vertex form is: f (x) = a(x - h)^2<span> + k and (h, k) is the vertex.
So plug in. f(x)=a(x+1)^2-10
Plug in x and y to find k.
2 = a(1+1)^2-10
2=a(2)^2-10
2=4a-10
4a=12
a=3
f(x)=3(x+1)^2-10
H is the answer.</span>
The equation of the parabola is y - 1 = (2/3) * (x - 3)².
<h3>What is equation of the parabola ?</h3>
The general equation of a parabola is: y-k = a(x-h)²
(h, k) - Coordinates of the vertex.
a - Vertex constant
Here:
(h, k) = (3, 1) and (x, y) = (0, 7).
So,
7 - 1 = C · (0 - 3)²
6 = 9 · C
C = 2/3
