Which of the following equations matches the function shown above?
Ksenya-84 [330]

So, the function is obviously shifted up by 1 so it rules out A and B, and we also see that the period is 4pi rather than 2pi, and using the fact that:

\frac{2\pi}{b}=4\pi \implies \frac{b}{2\pi}=\frac{1}{4\pi}\implies b=\frac{1}{2}

Now that we know our b value, we see that the correct answer would be C.

The path of a ball kicked from the ground can be modeled by the equation y=−1/5(x−5)(x−20), where x and y are measured in feet.
Helen [10]

Answer:

Step-by-step explanation:

This is already factored for the zeros of the quadratic.  If x - 5 = 0 and x - 20 = 0 then x = 5 and 20.  The ball was kicked 5 feet out and landed at 20 feet down the field.  The difference is 15 feet.  That's how far the ball traveled from its initial position on the ground to its landing place.

So 15 feet from where it was kicked.

Jessica, Miguel, and Dan sent a total of 75 text messages over their cell phones during the weekend. Dan sent 3 times as many me
SCORPION-xisa [38]

Answer:

number of messages sent by Jessica = 17

Number of messages sent by Miguel = 7

Number of messages sent by Dan = 51

Step-by-step explanation:

Let number of messages sent by Jessica = x

As per given statement,

Number of messages sent by Dan = 3 \imes x and

Number of messages sent by Jessica are 10 more than that of Miguel.

So, Number of messages sent by Miguel are 10 lesser than that of Jessica.

Number of messages sent by Miguel = x-10

It is also given that,

Total number of messages sent = 75

Adding the number of messages sent by each one of them and putting them equal to 75:

x+3x+x-10=75\\\Rightarrow 5x-10=75\\\Rightarrow 5x=85\\\Rightarrow x=17

So, number of messages sent by Jessica, x = 17

Number of messages sent by Miguel, x-10 = 7

Number of messages sent by Dan, 3x = 3\times17 = 51
