Mathematics

Answer:

(t•s )(x) = 4x^3 - 29x^2 + 10x - 21

Step-by-step explanation:

(t•s )(x) is the product of functions s and t:

(t•s )(x) = ( 4x^2 - x + 3)(x - 7).  Applying the Distributive Property of Multiplication, we get:

(t•s )(x) = 4x^3 - 28x^2 - x^2 + 7x + 3x - 21

which needs to be simplified by combining like terms:

(t•s )(x) = 4x^3 - 29x^2 + 10x - 21

2n-7/3 = 15 solve for n
WITCHER [35]
2n- \frac{7}{3} =15 
2n- \frac{7}{3} =15  common denominator is 3
3(2n- \frac{7}{3} )=3*15 distributhing  3 through parantheses
3*2n- \frac{3*7}{3}=3*15
3*2n-7=3*15
6n-7=45   add7
6n=45+7
6n=52 divide by 6
n= \frac{52}{6} simplify
n=8 \frac{2}{3} ⇒ \frac{26}{3}

4. Sam's parents are teachers who commute 45 miles roundtrip to work 5 2 days a week. His parents spend $38 on gasoline each wee
Marat540 [252]
<h2>Answer:</h2><h2>The correct option is d. (i) and (ii)</h2>

Step-by-step explanation:

The total miles covered per day = 45

No of commuting days in a week = 5

Total miles in a week = 45 * 5 = 225

The total amount spent on gasoline = $ 38

Cost of gasoline per gallon = $ 2.48

The number of gallons consumed per week = \frac{38}{2.48} = 15.32 gallons of gasoline per week.

This confirms (ii) statement

The amount spend on gasoline per mile = \frac{38}{225} = $0.17

This confirms (i) statement

The number of miles per gallon of gasoline = \frac{225}{15.32} = 14.68 miles

The statement (iii) is false.

Mkey [24]

Answer:

=\left(-\frac{19}{2},\:-2\right)

Step-by-step explanation:

\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-10,\:5\right),\:\\\left(x_2,\:y_2\right)=\left(-9,\:-9\right)\\\\=\left(\frac{-9-10}{2},\:\frac{-9+5}{2}\right)\\\\Simplify \\=\left(-\frac{19}{2},\:-2\right)
