Find the value of f(3) for the function.<br> f(a)=2(a+4)-3<br> f(3)=___ (simplify your answer)
Nonamiya [84]

Answer:

<h3>Given =><em><u> </u></em><em><u>f(a)=2(a+4)-3</u></em></h3><h3>To Attain=> <em><u>The value of f(3) for the function</u></em></h3>

Step-by-step explanation:

• By Putting the value of a = 3

•f(a)=2(a+4)-3

=>

f(3) = 2(3 + 4) - 3 \\ f(3) = 2 \times 7 - 3 \\ f(3) = 14 - 3 \\ f(3) = 11

• Hence, <em><u>1</u></em><em><u>1</u></em><em><u> </u></em><em><u>is </u></em><em><u>the </u></em><em><u>solution</u></em><em><u> </u></em><em><u>to </u></em><em><u>the </u></em><em><u>function</u></em><em><u> </u></em>

Can someone please solve this
katen-ka-za [31]

Answer:

RPQ = 239°

Step-by-step explanation:

Since SP is a straight line going through the center of a circle, it is a diameter.

We can say that m<SOR and m<ROP are supplementary and add up to 180° because they form a straight line. We can set up an equation:

m<SOR + m<ROP = 180°

We can substitute in the value of m<SOR:

31° + m<ROP = 180°

m<ROP = 149°

Next, we can also say that m<SOQ and m<QOP are supplementary because they form a straight line. Also, since QO is perpendicular to SP, we can say that both m<SOQ and m<QOP equal to 90°.

Now, we can say that m<ROQ (reflex angle) is equal to the sum of m<QOP and m<ROP from angle addition postulate. We can write the equation:

m<ROQ = m<QOP + m<ROP

m<ROQ = 90° + 149° = 239°

The reflex angle <ROQ cuts the arc RPQ, so they would have the same measure. So, arc RPQ = 239°
