The graph of the function f(x)=−4(x−3)2+9 will be a parabola opening in which direction?
sesenic [268]

Answer:

downwards

Step-by-step explanation:

the equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

• if a > 0 then parabola opens upwards

• if a < 0 then parabola opens downwards

for

f(x) = - 4(x - 3)² + 9 with a = - 4 < 0 , then

the parabola opens downwards

harina [27]

Answer:

1. y=7.2

2. x=18

Step-by-step explanation:

1. Triangles CMN and CBA are similar triangles (by AAA postulate). Similar triangles have proportional corresponding sides, so

\dfrac{CM}{CB}=\dfrac{CN}{CA}\\ \\\dfrac{12}{12+y}=\dfrac{10}{10+6}\\ \\12\cdot 16=10\cdot (12+y)\\ \\192=120+10y\\ \\10y=72\\ \\y=7.2

2. GK is angle G bisector. Use angle bisector's property:

\dfrac{GH}{GI}=\dfrac{KH}{KI}\\ \\\dfrac{40}{24}=\dfrac{30}{x}\\ \\40x=24\cdot 30\\ \\4x=24\cdot 3\\ \\x=6\cdot 3=18

The Law of Large Numbers: I need help on finding the probability of this situation.
Stella [2.4K]

The mean time it takes to walk to the bus stop is 8 minutes (with a standard deviation of 2 minutes) and the mean time it takes for the bus to get to school is 20 minutes (with a standard deviation of 4 minutes). The distributions are normal. a. How long will it take (in minutes), on average, to get to school? b. What is the standard deviation of the trip to school? c. What is the probability that it will take longer than 30 minutes to get to school? Due to a miscalculation, you realize it actually takes an average of 10 minutes to walk to the bus stop. d. How long will it take (in minutes), on average, to get to school? e. What is the standard deviation of the trip to school? f. What is the probability that it will take longer than 30 minutes to get to school? The only ones I need help with is C and F. I have the answer for the rest of them. Can someone please help me with parts C and F??
