jasenka [17]3 years ago

Answer:

Option 3. f(x) is g(x) stretched vertically by a factor 8 and reflected about the x axis.

Step-by-step explanation:

The given functions are F(x) = -\frac{1}{2} sin5x----(1)

and g(x) = 4sin5x ------(2)

In the function (1)

F(x) = -\frac{1}{2} sin5x

Amplitude A = \frac{1}{2}

In the function (2)

g(x) = 4sin5x Amplitude A' = 4

So when we compare these graphs we get

\frac{A'}{A}=\frac{4}{\frac{1}{2} }\frac{A'}{A}= (\frac{4}{1})(\frac{2}{1})

A' = 8A

Since the Graph number (2) is of positive sign that means Graph (1) is reflected about the x axis to get (2)

Therefore Option 3 is correct f(x) is stretched vertically by a factor of 8 and reflected by X axis

pychu [463]

Answer: V≈900 ft³

Step-by-step explanation:

Formula

V=πr²h

Given

r=5 ft

h=12 ft

Solve

V=πr²h

V=π(5)²(12)

V=π(25)(12)

V=300π

V≈300(3)

V≈900 ft³

Hope this helps!! :)

belka [17]

Answer:

Step-by-step explanation:

We are told the school sold raffle tickets, and each ticket has a digit either 1, 2, or 3. The school also sold 2 tickets with the number 000.

Therefore we have the following raffle tickets:

123

132

213

231

312

321

000

000

From the given information, we can deduce that the school sold 8 tickets and only one ticket can contain the number arrangement of 123, but 000 appeared twice.

Probability of 123 to be picked=

1/8 => 0.125

Probability of 000 to be picked=

2/8 => 0.25

Since the probability of 000 to be picked is greater than 123, a ticket number of 000 is more likely to be picked
