When x=0, y=4...
Therefore:
4=a*b⁰
b⁰=1, so a=4.
----------
When x=1, y=2...
Therefore:
2=4*b¹
4b=2
b=2/4
So... b=1/2.
This means that:
y=4*((1/2)^x)
Since the train travels 50 miles in 1 hour, to find 3/4 of an hour:
3/4 * 50
75/2 miles
Hope this helps!
Answer:
B= 15 cm²
Step-by-step explanation:
The base of the triangular shaped wedge of cheese is a right-triangle.To find the area of a right-triangle you apply the formula for half base by height.
A=1/2*b*h = base area = B
In this case, assume the sides of the triangle given are; a=5 cm and b=6 cm, thus area will be 1/2*6*5 =15 cm²
B= 15 cm²
You cut off the edge. No matter; we have two pairs of congruent angles, and included side AC is congruent to itself, so we have everything we need to invoke
Answer: ASA, the Angle-Side-Angle triangle congruent theorem
