Answer:
A. 1/2
Step-by-step explanation:
The original figure has a side of 4 and the reduced figure has a side of 2
4:2
What do we multiply to get from 4 to 2
4x =2
Divide each side by 4
4x/4 = 2/4
x = 1/2
The scale factor is 1/2
Answer:
Answer
Step-by-step explanation:
Converted to kilometers, 89.25 centimeters would be 0.0008925 kilometers
The least common demoniator is 168
Cm is a centimeter, which is one-hundredth of a meter. Or rather, one hundred centimeters is equal to one meter.
To convert cm to meters
(62.5 cm) * (1 meter/100 cm) = .625 meters
Answer:
x = 1 and vertex = (1, - 7 )
Step-by-step explanation:
Given a quadratic function in standard form
y = ax² + bx + c ( a ≠ 0 )
The the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = -
y = 4x² - 8x - 3 ← is in standard form
with a = 4, b = - 8 , then
x = - = 1
That is equation of axis of symmetry is x = 1
Substitute x = 1 into the function for y- coordinate of vertex
y = 4(1)² - 8(1) - 3 = 4 - 8 - 3 = - 7
vertex = (1, - 7 )
