Answer:
Step-by-step explanation:
The standard form of a quadratic is
where h is side to side movement (it's also the x coordinate of the vertex) and k is the up or down movement (it's also the y coordinate of the vertex). If there is no up or down movement, the k value is 0. (We don't need to worry about the value for a here; it's 1 but that doesn't change anything for us in our problem). Movement to the right is positive, so we are moving +10. Filling that into our equation:
and simplified:
That is the parent graph shifted 10 units to the right.
First, convert your mixed numbers into improper fractions, so 8+3/8=69/8 and 2+1/3=7/3. Now you have 69/8=r-(7/3). Now, add 7/3 to both sides, so (69/8)+(7/3)=r. Now, just add your fractions, so (69/8)+(7/3)=207/24+56/24=(207+56)/24=263/24. If you need to, this can be converted back into the mixed number 10+23/24.
The answer to the question is b
Answer:
B) 4% of 52
Step-by-step explanation:
A) 0.25 x 52 = 13
B) 4% of 52 = 0.04 x 42 = 2.08
C) 52 ÷ 4 = 13
D) 52/4 = 13
A² + b² = c²
a = 2b, c = 10
(2b)² + b² = 10²
4b² + b² =100
5b² = 100
b² = 100 ÷ 5
b² = 20
Answer: 20
