Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x
+1?
Oright 1 unit
o left 1 unit
Oright 2 units
left 2 units
Answer:
The translation is left 1 unit, up 5 units ⇒ A
Step-by-step explanation:
Let us revise the rules of translation of a function
If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k
The vertex form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant is f(x) = a(x - h)² + k, where h = and k = f(h)
You will use the vertex form to find the translation
∵ g(x) = x² + 2x + 6
∴ a = 1 and b = 2
→ use the rule of h to find it
∴ h =
∴ h = -1
→ Use it to find k
∵ g(h) = k
∴ k = g(-1)
→ Substitute x by -1 in g to find k
∴ k = (-1)² + 2(-1) + 6 = 1 - 2 + 6
∴ k = 5
→ Substitute the values of h and k in the vertex form above
∴ g(x) = 1(x - -1)² + 5
∴ g(x) = (x + 1)² + 5
→ By using the 2nd and 3rd rules of translation above
∴ f(x) is translated 1 unit to the left and 5 units up
∴ The translation is left 1 unit, up 5 units
Answer:
it's A. left 1 unit

A 11 1/4 candle burns in 9 hours at what rate does the candle burn per hour
i really need help on this one
Answer:
Step-by-step explanation:
Answer:
The candle burns out 1 [tex]\frac{1}{4}[/tex] per hour. (or [tex]\frac{5}{4}[/tex])
Step-by-step explanation:
1. Convert 11 [tex]\frac{1}{4}[/tex] into an improper fraction ([tex]\frac{45}{4}[/tex])
2. Divide [tex]\frac{45}{4}[/tex] by 9 to find the rate
3. You should get 1 [tex]\frac{1}{4}[/tex] (mixed number) or keep it as an improper fraction( [tex]\frac{5}{4}[/tex] )

One week, Brooklyn earned $179.30 at her job when she worked for 11 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $244.50?
Answer:
Brooklyn would get paid 16.30 hourly. So she will have to work 15 hours the next week to earn 244.50.
Step-by-step explanation:
Divide 179.30 by 11 and you would get 16.30 which is her hourly wage. Then you divide 244.50 by 16.30 to see how many hours she would have to work to earn 244.50.
Answer:
15 Hours
Step-by-step explanation:
179.30 / 11 = $16.3 an hour
244.5 / 16.3 = 15 hours

Answer:
131.63
Step-by-step explanation:
Sample method: Use properties of operations. Let x represent the markup.
x98.75=33.3100 Write the proportion.
x98.75=0.333 Divide 33.3 by 100.
98.75 · x98.75=(0.333)∙98.75 Multiplication Property of Equality
x=32.88 Simplify.
Add the markup to the wholesale cost.
The selling price is $98.75+$32.88 or $131.63.
