Use the functions h(x) = 2x + 5 and t(x) = 7x − 6 to complete the function operations listed below.

1 answer:

6 0

We have to use the functions:
h ( x ) = 2 x + 5 and t ( x ) = 7 x - 6
Part A:
( h + t ) ( x ) = ( 2 x + 5 ) + ( 7 x - 6 ) = 9 x - 1
Part B :
( h · t ) ( x ) = ( 2 x + 5 ) · ( 7 x - 6 ) = 14 x² - 12 x + 35 x - 30 =
= 14 x² + 23 x - 30
Part C :
h [ t ( x ) ] = h ( 7 x - 6 ) = 2 · ( 7 x - 6 ) + 5 = 14 x - 12 + 5 =
= 14 x - 7

A telephone solicitor is responsible for canvassing three suburbs. In the past, 60% of the completed calls to Belle Meade have r

igor_vitrenko [27]

Answer:

0.4625 or 46.25%

Step-by-step explanation:

The data for the percentage of contribution and the percentage of numbers from each suburb is presented in the table bellow:

$\begin{array}{ccc}&Contribution (C)&Number(N)\\Belle\ Mead&0.60&0.25\\Oak\ Hill&0.55&0.25\\Antioch&0.35&0.5\end{array}$

The probability that she gets a donation is given by the sum of the probabilities of getting a donation from each suburb weighed by their respective percentage of numbers of the list:

$P(C) = P(C_B)+P(C_O)+P(C_A)\\P(C) =0.6*0.25+0.55*0.25+0.35*0.5\\P(C) = 0.4625$

The probability that she gets a donation is 0.4625 or 46.25%.

A circular tabletop has a circumference of 94.2 inches. What is its approximate area?

kiruha [24]

Since Circumference is $C=2 \pi r$
So to get Area, you have to get the radius first:
$C=(2)3.14r$ , which is $94.2=6.28r$
Next we divide both sides by $6.28$ to get:
$Radius=15in.$
Now we have to get the area which is $A= \pi r^2$
Plug in 15 for r, you should get $A=[(3.14)(15)]^2$
Final Answer: $A=706.86in.$
