bulgar [2K]

Answer:

Part a)

Steve's expression is $2(2x+5)^{2}-7$

For x=3, the expression is equal to $235$

Part b)

Jasmine's expression is

$(3x^{2})+(25x)$

For x=2, the expression is equal to $62$

Step-by-step explanation:

Part a)

Let

n-----> the first term

The expression is

$(n-7)$

$n=2(2x+5)^{2}$

substitute

Steve's expression is

$2(2x+5)^{2}-7$

Evaluate for x=3

$2(2(3)+5)^{2}-7=242-7=235$

Part b)

Let

n-----> the first term

Jasmine's expression is

$(3x^{2})+(25x)$

Evaluate for x=2

$(3(2)^{2})+(25(2))=12+50=62$

Five applicants are to be scheduled for job interviews at five given times. On an application form, each applicant was asked to

dlinn [17]

Answer:

0.01024

Step-by-step explanation:

Assume marking was done at random : Hence, each of the 5 time slots have equal Chamves of being marked ;

Number of time slots, n = 5

Required to mark, number of preferred timeslot x = 2

P(x) = 2 /5 = 0.4

Probability of 0.4 that an interviewee gets one of his preferred timeslot.

Probability that each of the 5 interviewees gets one of their preferred time slots :

Using the multiplication rule of independence :

0.4 * 0.4 * 0.4 * 0.4 * 0.4 = 0.4^5 = 0.01024

0.01024 * 100% = 1.024%

What is the following product? 3√2(5√8-7√3)

vovangra [49]

Answer:

3√2(5√8-7√3) = 60 - 21√6

Step-by-step explanation:

We need to find the product of 3√2(5√8-7√3). The distributive property states that: A(B+C) = AB + AC.

Then, by using the distributive propertive we have that:

3√2(5√8-7√3) = 3√2 * 5√8 - 3√2 * 7√3 = 15√8√2 - 21√2√3.

Also, we know that: √A√B = √AB. Using this:

15√8√2 - 21√2√3 = 15√16 - 21√6 = 60 - 21√6.

Label the vertices A (- 3, - 2), B (- 7, - 3 ), D (- 4, - 5 )

and the centre of dilatation C (- 7, - 6 ), then

CA = a - c = < - 3, - 2 > - < - 7, - 6 > = < 4, 4 >

CA' = 3 < 4, 4 > = < 12, 12 >

A' = (- 7 + 12, - 6 + 12 ) = ( 5, 6 )

CB = b - c = < - 7, - 3 > - < - 7, - 6 > = < 0, 3 >

CB' = 3 < 0, 3 > = < 0, 9 >

B' = (- 7 + 0, - 6 + 9 ) = (- 7, 3 )

CD = d - c = < - 4, - 5 > - < - 7, - 6 > = < 3, 1 >

CD' = 3 < 3, 1 > = < 9, 3 >

D' = (- 7 + 9, - 6 + 3 ) = ( 2, - 3 )

Summarising

(- 3, - 2 ) ⇒ (5 , 6 )

(- 7, - 3 ) ⇒ (- 7, 3 )

(- 4, - 5 ) ⇒ (2, - 3 )
