It’s C FHG = CDE
Because angle F = angle C and line FH equals line CD and angle H equals angle D
For each of the given answer choices, substitute the x-value into the given equation f(x) = 3(1/4)^x and see the equation gives the same f(x), or y-value.
Remember f(x) is the same thing as y and so coordinates for a point are in problem is (x, f(x))
Let's try the first coordinate (-2, 48). The x-value given by the coordinate is -2 and the f(x) value is 48.
Substituting x as -2
into the equation,
This matches with the answer choice (-2, 48) so A should be correct.
But you can also check the other answer using the same process to make sure.
Answer:
When you multiply or divide both sides of an inequality by a negative number, the inequality reverses.
For example 1 < 2, but -1 > -2 (-2 is to the left of -1)
Step-by-step explanation:
Answer:
Step-by-step explanation:
you have to do the y/x method and subtract each from eachother if there equal then it's a trapezoid
Answer:
A = 44.2cm²
Step-by-step explanation:
The surface area of a square pyramid that has the sides of the base of 4 cm and a height of 10 cm is 44.2cm².
Formula: A=AB(4h2+AB)+AB
A=AB(4h2+AB)+AB=4·(4·102+4)+4≈44.1995cm²
