If p(x) = 2x - 5 and r(x) = 3x + 4, calculate (pr)(x).
A 6x2 - 7x - 20
B 6x² +7X-20
C 5x - 1
D 6x2 - 20

Answers

Answer:

A) 6 x² - 7x - 20

Step-by-step explanation:

Explanation:-

Given p(x) = 2 x-5 and r (x) = 3 x +4

(pr)(x) = p(x) r(x)

= (2x -5)( 3 x +4)

= 2x(3x +4) -5( 3x +4)

= 6 x² + 8x - 15 x - 20

= 6 x² - 7x - 20

(pr)(x) = 6 x² - 7x - 20

The school that Alberto goes to is selling tickets to a fall musical. On the first day of ticket sales
the school sold 6 senior citizen tickets and 2 child tickets for a total of $96. The school took in
$120 on the second day by selling 6 senior citizen tickets and 4 child tickets. Find the price of a
senior citizen ticket and the price of a child ticket.

Answers

Answer:

The price of both tickets is $12 each

Step-by-step explanation:

System of Equations

Let's call:

x = price of a senior citizen ticket

y = price of a child ticket.

On the first day of ticket sales, the school sold 6 senior citizen tickets and 2 child tickets for $96. Setting up the first equation:

6x + 2y = 96

Dividing by 2:

3x + y = 48 [1]

On the second day, the school sold 6 senior citizen tickets and 4 child tickets for $120:

6x + 4y = 120

Dividing by 2:

3x + 2y = 60 [2]

Subtracting [2] and [1]:

2y - y = 60 - 48

y = 12

From [1]:

3x + 12 = 48

3x = 48 - 12 = 36

x = 36/3 = 12

x = 12

The price of both tickets is $12 each

Step-by-step explanation:

A contractor bought 7.6 ft2 of sheet metal. She has used 3.5 ft2 so far and has $123 worth of sheet metal remaining. The equation 7.6x−3.5x=123 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?

Answers

Answer:

Sheet metal remaining = 4.1x

cost per square foot of sheet metal = $30

Step-by-step explanation:

Total sheet metal bought = 7.6 ft2

Total sheet metal used = 3.5 ft2

Given equation:

7.6x − 3.5x = 123

Where,

x = cost per square foot

7.6x − 3.5x

Sheet metal remaining = 4.1x

7.6x − 3.5x = 123

4.1x = 123

x = 123 / 4.1

x = $30

Cost per square foot = $30

On a unit circle, the terminal point of Ø is (1/2, square root 3/2), what is the cos Ø?

A. 1/2
B. Square root 3/3
C. Square root 3/2
D. Square root 3

Answers

The cosine of Ø is: [tex]\frac{1}{2}[/tex]

The ordered pair of a unit circle is represented as:

[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]

The given parameters can be represented as:

[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]

Recall that:

[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]

Compare the above representation to:

[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]

This means:

[tex]\cos(\theta) = \frac{1}{2}[/tex] and [tex]\sin(\theta) = \frac{\sqrt 3}{2}[/tex]

Answers

That is TRUE. If you combine like terms you get:
3y + 9 = 3y + 9

Its true, its combine like term : 2y + y = 3y and 3 + 2 + 4 = 9! Which is 3y + 9!

The roof of a building is 9 m high. A rope is tied from the roof to a peg on the ground 12 m away from the wall. What is the length of the rope?

Answers

Answer:

15 m

Step-by-step explanation:

Height of buiding h= 9m

Lenght from building l= 12m

let the length of the rope be x=???

Applying Pythagoras theorem

x^2=h^2+l^2

x^2= 9^2+12^2

x^2= 81+144

x^2=225

square both sides

x=√225

x=15 m

Hence the length of the rope is 15 m

Someone please help?? This is constant of proportionality... I don't get it at all and I need to turn this is ASAP!!!

Answers

Answer:

Step-by-step explanation:

From the given graph the line is straight ,so it means that the relation between x and y is directly proportional

(or) you can also say that at each point the slope of the line is same

slope =y/x , slope= 26/2 = 65/2 = 117/9 =13

hence slope is same that's why relation between x and y is direct relation

y∝ x

y=k*x

k=y/x

putt any point one the line to find the value of constant of proportionality,

i putt (2,26)

k=26/2 =13 value of proportionality constantnow to find cost of 14 tickets ,we have y=13*x , now putt x=14we will get cost(its on y-axis while ticket is on x-axis)y=13*14y= $182 cost of 14 ticketsso "C" option is correct
