Answer:
276 inches
Step-by-step explanation:
First we need to convert 32 feet to inches.
The conversion factor is 12 inches to 1 foot.
Hence,
32 feet = 32 * 12 = 384 inches
In January, she orders 9 fewer feet. That is 32 - 9 = 23 feet
Let's convert this to inches:
23 * 12 = 276 inches
So, she orders 276 inches
Answer:
f(0) = 0 and f(−2) = f(2)
Step-by-step explanation:
Given: the function f defined by f(x) = 3x²
f(0) = 3(0)²
f(0) = 0
f(-2) = 3(-2)²
f(-2) = 3(4)
f(-2) = 12
f(2) = 3(2)²
f(2) = 3(4)
f(2) = 12
Hence f(-2) = f(2)
Therefore the correct options are f(0) = 0 and f(−2) = f(2)
The vertices of triangle QRS have coordinates Q(1, −2), R(3, −2), and S(2, −4). The coordinates are the coordinates of the vertices of triangle QꞌRꞌSꞌ when triangle QRS is reflected across the x-axis <span>Qꞌ(1, 2), Rꞌ(3, 2), Sꞌ(2, 4). The answer is letter B.</span>
