The price that John would pay for the new laptop after accounting for the sales, price coupon and the sales tax is  0.72p.

After the sales price and coupon is applied, the price of the laptop would reduce.

Price after the sales price = (1 - 0.2) x p = 0.8p

Price after the coupon = (1 - 0.15) x 0.8p

0.85 x 0.8p = 0.68p

A tax increases the price of the laptop.

Price after the tax = (1 + 0.06) x 0.68p = 1.06 x 0.68p = 0.72p

Step-by-step explanation:

Slope of the line indicate how fast ( or slow ) the line is going up or down

The number of infected banana plants with a rate of 8% will be in 8 years is 848.

Consider the function:

y = a(1 + r)ˣ

where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

A blight is spreading on a banana plantation. Currently, 458 banana plants are infected.

If the disease is spreading at a rate of 8% each year.

Then the number of the plants that will be infected in 8 years.

Then the exponential function is given as

y = 458(1.08)ˣ

At x = 8, then we have

y = 458(1.08)⁸

y = 458 x 1.851

y = 847.73

y ≅ 848

[tex]y = 3x-2\\\\~~~=3(-5) -2\\\\~~~= -15-2\\\\~~~= -17[/tex]

Answer:

y = -17

Step-by-step explanation:

Given values :

Let's substitute in the expression to find y :

⇒ y = 3(-5) - 2

⇒ y = -15 - 2

⇒ y = -17

The speed when the power is 2000watts is 22.5m/s

If the power, P (watts), of a car engine is proportional to the square of its

speed, s(m/s), this is expressed as:

P = k/s

When s=25, P=1800 then;

1800 = k/25
k = 25 * 1800
k = 4500

In order to calculate the speed when the power is 2000;

s = k/p
s= 4500/2000
s = 22.5m/s

Hence the speed when the power is 2000watts is 22.5 m/s

The volume of the rectangular prism with length 7 yards, width 6 yards, and height 3 yards is 126 cubic yards

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that rectangular prism with length 7 yards, width 6 yards, and height 3 yards.

We have to find the volume of the prism

Volume = length×width ×height

Plug in the values of length , width and height

Volume = 7×6×3

=126 cubic yards

Hence, the volume of the rectangular prism with length 7 yards, width 6 yards, and height 3 yards is 126 cubic yards

Explanation:

[tex]\sf Find \ slope \ (a) : \sf \ \dfrac{y_2 - y_1}{x_2- x_1} \ = \ \dfrac{-10-(-7)}{10-0} \ = -0.3[/tex]

Answer:

[tex]g(x)=-\dfrac{3}{10}|x|-7[/tex]

Step-by-step explanation:

Translations

For [tex]a > 0[/tex]

[tex]f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}[/tex]

[tex]y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis by a factor of}\:a[/tex]

[tex]y=-f(x) \implies f(x) \: \textsf{reflected in the} \: x \textsf{-axis}[/tex]

-----------------------------------------------------------------------------------------

Parent function:  [tex]f(x)=|x|[/tex]

From inspection of the graph, the transformed function has been reflected in the x-axis.

[tex]\implies -f(x)=-|x|[/tex]

The vertex of the parent function is the origin (0, 0).  The vertex of the transformed function is at (0, -7).  Therefore, there has been a translation of 7 units down.

[tex]\implies -f(x)-7=-|x|-7[/tex]

From inspection of the graph, we can see that it has been stretched parallel to the y-axis:

[tex]\implies -a\:f(x)-7=-a|x|-7[/tex]

The line goes through point (10, -10)

Substituting this point into the above equation to find [tex]a[/tex]:

[tex]\implies -a|10|-7=-10[/tex]

[tex]\implies -10a=-3[/tex]

[tex]\implies a=\dfrac{3}{10}[/tex]

Therefore,

Answer:

x = 14

Step-by-step explanation:

3(x + 1) = 45

3*x + 3*1 = 45    {Distributive property used: a*(b+c) =(a*b) +(a*c)}

3x + 3    = 45

   Subtract 3 from both sides

         3x = 45 - 3

         3x = 42    

Divide both sides by 3

          x  = 42/3

The transformation from the parent function f(x) to g(x) is (b) g(x) is shifted 2 units to the right and 6 units up

The equations are given as:

f(x) = x^3

g(x) = (x - 2)^3 + 6

The transformation from f(x) to g(x) can be represented as:

x -> x -2

f(x) -> f(x) + 6

This means that the function f(x) is shifted right by 2 units and shifted up by 6 units.

Hence, the transformation from the parent function f(x) to g(x) is (b) g(x) is shifted 2 units to the right and 6 units up

Step-by-step explanation:

Q8.

Let h be the height of the flagpole

     x be the distance between point P and the flagpole.

8.1.

tan(53) = h/x

⇒ h = xtan(53)   (1)

On the other hand ,

tan(28) = h/(x+20)

⇒ h = (x+20)tan(28)   (2)

Let’s equate equation so (1) and (2) :

⇒ xtan(53) = (x+20)tan(28)

⇒ x = 20tan(28) ÷ (tan(53) - tan(28)) = 13.370697151775

from (1) , we have :

h = xtan(53)

  = 13.370697151775×tan(53)

  = 17.743514416718

Area ABCD = area ABD + area BCD

area ABD = (1/2) AB AD sin(BAD)

                = (1÷2)×11×7×sin(110)

                =36.178165900258

area BCD =  (1/2) DB DC sin(BDC)

firsly , we need to calculate DB (using the law of cosines I need triangle ABD) :

DB² = AB² + AD² - 2AB AD cos(110)

      = 11^2+7^2-2×11×7×cos(110)

      = 222.671102072153

Then

DB = √(222,671102072153)

     = 14.92216814247

Going back ,

area BCD =  (1/2) DB DC sin(BDC)

                = (1÷2)× (14,92216814247)×16×sin(40)

                =76.734278333111

Conclusion :

Area ABCD = area ABD + area BCD

                   = 36.178165900258+ 76.734278333111

                   = 112.912444233369
