Find f(1) and f(5)?

Mathematics
1 answer:
Nitella [24]2 years ago
5 0

Hello and Good Morning/Afternoon:

<u>Let's take this problem step by step</u>

<u />

<u>First part (a)</u>

  • Find f(1)

           \hookrightarrow \text{which is found by plugging '1' into t's position}\\    f(1)=24(1)^2-93(1) +78=24-93+78\\f(1)=9

  • Find f(5)

           \hookrightarrow \text{ which is found by plugging '5' into t's position}\\f(5) = 24(5)^2-93(5) + 78 = 24*25-93*5+78 \\f(5)=213

<u>Second part (b)</u>      

\hookrightarrow \text {By comparing the calculated data in part (a) to the actual data in part (b)}\\\hookrightarrow \text{We can note that the actual data matches more closely with the calculated data}\\\hookrightarrow \text{ in later years}\\\hookrightarrow \text{ Thus the model is more accurate in later years}

<u />

<u>Answer:</u>

  • <u>(a) f(1) = 9 , f(5) = 213</u>
  • <u>(b) The model is more accurate in later years</u>

<u></u>

Hope that helps!

Angles 5 and 6 are vertical angles because they are formed by two intersecting lines

Angles 1 and 2 are none of these. They are not vertical angles because they aren't directly across from each other like angles 5 and 6. They aren't adjacent angels because they aren't next to each other. They aren't a linear pair because they aren't adjacent along a straight line.

Hope this helps

Sin(x+24) = Cos(y-x) ; Tan(z-24) - Tan(y-z)=0<br><br> find: Cos(y-z)
Delvig [45]
<h3>Answer:</h3>

Cos(y-z) = Cos(z-24)

<h3>Step-by-step explanation:</h3>

You have two equations in three unknowns, so no solution for the unknowns is possible.

The tangent equation tells you ...

... tan(z -24) = tan(y -z)

... z -24 = y -z . . . . . . take the arctangent

... cos(y -z) = cos(z -24) . . . . take the cosine
