Find p(4) for the function.
2. p(x) = 7x2 - 9x + 10

Answer:

6x+18=73

Step-by-step explanation:

Rectangle area w*l

(x+3)*6=73

6x+18=73

cos⁸A+sin⁸A = (Cos⁴A)² + (Sin⁴A)²

=> (Cos⁴A + Sin⁴A)² - 2Cos⁴ASin⁴A

=> [(Cos²A)²+(Sin²A)²]² - 2(CosASinA)⁴

=> [(Cos²A+Sin²A)² - 2Cos²ASin²A]² - 2(CosASinA)⁴

=> [1 - 2Cos²ASin²A]² - 2(CosASinA)⁴

=> [1 - 2(CosASinA)²]² - 2(CosASinA)⁴

//Remember: Sin2A = 2SinA CosA => SinACosA = 1/2Sin2A

=> [1 - 2(1/2Sin2A)²]²- 2(1/2Sin2A)⁴

=> [1 - 1/2Sin²2A]² - 1/8Sin⁴2A

=> 1 + 1/4Sin⁴2A - Sin²2A - 1/8Sin⁴2A

=> 1 - Sin²2A + 1/8Sin⁴2A

=> R.H.S

Answer:

All you need to do is plug the values and then simplify!

[tex] \large{ \tt{ - 2x + 3y}}[/tex]

[tex] \longrightarrow \: \large{ \tt{ - 2 \times ( - 2) + 3 \times ( - 5)}}[/tex]

[tex] \longrightarrow \large{ \tt4 + ( - 15){}}[/tex]

[tex] \longrightarrow \large{ \tt{4 - 15}}[/tex]

[tex] \longrightarrow{ \large{ \boxed{ \tt{ - 11}}}}[/tex]

Answer:

9

Step-by-step explanation:

Simplifying

2y + -6 = 12

Reorder the terms:

-6 + 2y = 12

Solving

-6 + 2y = 12

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '6' to each side of the equation.

-6 + 6 + 2y = 12 + 6

Combine like terms: -6 + 6 = 0

0 + 2y = 12 + 6

2y = 12 + 6

Combine like terms: 12 + 6 = 18

2y = 18

Divide each side by '2'.

y = 9

Simplifying

y = 9

Answer:

Y=9

Step-by-step explanation:

Subtract 6 from both sides. Simplify. Dive both sides of the equation by the same term. Simplify. Solution y=9

The values of :

The given equations are :

now, let's multiply both the equations with 10 on both sides.

so, now our equations will be :

from Equation second :

now, let's substitute the value of y from here into Equation first.

here, we got the value of x = 2, let's plug it in equation second to find value of y :

And value of y = 3

Answer:

Step-by-step explanation:

[tex]\large\underline{\sf{Solution-}}[/tex]

Given that,

A car covers the distance between two cities in 6 hours.

A van covers the same distance in 5.5 hours.

The speed of the van is 4 km per hour faster than the speed of car.

Let assume that

Speed of the car be x km per hour

So,

Speed of van is x + 4 km per hour.

Let further assume that

Distance between two cities be y km.

We know, Distance covered = Speed × Time.

➢ Now, Distance (y) covered by car at the speed of x km per hour in 6 hours is

[tex]\rm :\longmapsto\:\boxed{\tt{ y = 6x}} - - - - (1)[/tex]

➢ Also, Distance (y) covered by van at the speed of x + 4 km per hour in 5.5 hours is

[tex]\rm :\longmapsto\:\boxed{\tt{ y = 5.5(x + 4)}} - - - - (2)[/tex]

So, from equation (1) and (2), we have

[tex]\rm :\longmapsto\:6x = 5.5(x + 4)[/tex]

[tex]\rm :\longmapsto\:6x = 5.5x + 22[/tex]

[tex]\rm :\longmapsto\:6x - 5.5x = 22[/tex]

[tex]\rm :\longmapsto\:0.5x = 22[/tex]

[tex]\rm :\longmapsto\:\dfrac{5}{10} \times x = 22[/tex]

[tex]\rm :\longmapsto\:\dfrac{1}{2} \times x = 22[/tex]

[tex]\bf\implies \:x = 44[/tex]

On substituting the value of x, in equation (1), we have

[tex]\rm :\longmapsto\:y = 6 \times 44[/tex]

[tex]\bf\implies \:y = 264[/tex]

So,

[tex]\begin{gathered}\begin{gathered}\bf\: \rm :\longmapsto\:\begin{cases} &\sf{Distance \: between \: cities = 264 \: km} \\ \\ &\sf{Speed \: of \: car \: = \: 44 \: km \: per \: hour}\\ \\ &\sf{Speed \: of \: van \: = \: 48 \: km \: per \: hour} \end{cases}\end{gathered}\end{gathered}[/tex]

Answer:

subtract 3 from the product of 9 and m

Answer:

[tex]\displaystyle s = \frac{hz}{h-z}[/tex]

Step-by-step explanation:

We are given the equation:

[tex]\displaystyle z = \frac{sh}{s+h}[/tex]

And we want to solve it for s.

First, we can multiply both sides by the denominator:

[tex]\displaystyle z(s+h) = sh[/tex]

Distribute:

[tex]\displaystyle sz + hz = sh[/tex]

Subtract hz and sh from both sides:

[tex]\displaystyle sz - sh = -hz[/tex]

Factor:

[tex]\displaystyle s(z-h) = -hz[/tex]

And divide. Hence:

[tex]\displaystyle s = \frac{-hz}{z-h} = - \frac{hz}{z-h} = \frac{hz}{h-z}[/tex]

Any one of the above three forms are correct, although the third form is preferred because it omits the additional negative.

Answer:8.72

Step-by-step explanation:

26.16/3=8.72

Answer:

Cost per pound = $8.72

Step-by-step explanation:

Since Mrs. Thomas spent $26.16 for 3 pounds' worth of turkey, all you need to do is divide $26.16 by 3 to get the cost per pound.

$26.16 ÷ 3 pounds = $8.72 per pound of turkey

Step-by-step explanation:

Answer:

a. $77.5 for 5 tickets

b. You can by 8 tickets with $130

Step-by-step explanation:

Answer:

a) $77.50

b) 8 tickets

Step-by-step explanation:

a) C(x) = 17.5(x) - 10

C = 17.5(5) - 10

C = $77.50

b) C(x) = 17.5(x) - 10

130 = 17.5(x) - 10

130 + 10 = 17.5(x) -10 + 10

140 = 17.5(x)

140/17.5 = (x)

8 = x

Answer:

X=15
