Answer:

-3x^2+17x-20

Step-by-step explanation:

We have been given an expression (3x-5)(-x+4). We are asked to find the simplified product of the given expression in standard form.

Using distributive property a(b+c)=ab+ac, we will get:

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

-3x^2+12x+5x-20

Combine like terms:

-3x^2+17x-20

Therefore, the product of our given expression would be -3x^2+17x-20.

Line p is parallel to line q. if the measure of angle 3 is 54°, what is the measure of angle 6
Free_Kalibri [48]

Answer:

m\angle 6=54^o

Step-by-step explanation:

The complete question in the attached figure

we know that

When two lines are crossed by another line (transversal), a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal, are called <em><u>Alternate Interior Angles</u></em>.

When the two lines being crossed are Parallel Lines the Alternate Interior Angles are congruent

In this problem

m\angle 6=m\angle 3 ---> by alternate interior angles

we have

m\angle 3=54^o

therefore

m\angle 6=54^o

The weekly sales of Honolulu Red Oranges is given by
Volgvan

Answer: See Explanation

Step-by-step explanation:

The price elasticity of demand will be calculated as:

q = 860 − 20p.

dq/do = -20

p = 38

Elasticity E(p) = (p/q) × dq/dp

= [38 /(860 - 20p)] × (20)

=38 × 20/(860 - 760)

= 7.6

Therefore, the price elasticity of demand when the price is $38 per orange is 7.6

Revenue = price × quantity

= p × q

= p × (860 − 20p)

= 860p - 20p²

Differentiating with respect to p

= 860 - 40p

40p = 860

p = 860/40

p = 21.50

Maximum Revenue = 860p - 20p²

= 860(21.50) - 20(21.50)²

= 18490 - 9245

= 9245

Tricia is looking to buy speakers that cost $349 plus the sales tax rate, which is 2.7%. What is the total amount she will pay a
m_a_m_a [10]

Answer:

The total amount she will pay after taxes is $339.58

Step-by-step explanation:

The Total cost of the speaker plus tax = $349

The tax rate applied = 2.7%

Tax payable = $349 * 2.7% = $9.423

The tax amount on the speaker is Tricia = $9.423

Thus, the total amount she will pay after taxes (i.e. paying $9.423) for purchase of the Speaker will be = $349 - $9.423 = $339.58.

The original price of the speaker excluding tax is $339.58.

Answer:

9

41/4

23/2

51/4

14

Step-by-step explanation:

The first term is the first term that is given. Just copy it.

Each next term is the previous term plus the common difference.

First term: a_1 = 9

Second term: a_2 = 9 + 5/4 = 36/4 + 5/4 = 41/4

Third term: a_3 = 41/4 + 5/4 = 46/4 = 23/2

Fourth term: a_4 = 46/4 + 5/4 = 51/4

Fifth term: a_5 = 51/4 + 5/4 = 56/4 = 14
