pls help

Answer:

Solution for If f(x) = 2x – 6 and g(x) = x – 2x2, find each value. f(2)

The required value of each function is

f(h + 9) = 2(h + 6)

g(h + 9) = -(2h + 19)(h - 9)

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.

Now the given functions are,

f(x) = 2x – 6

g(x) = x – 2x²

Now putting x = h + 9 in f(x) and g(x)we get,

f(h + 9) = 2(h + 9) – 6

⇒ f(h + 9) = 2h + 18 – 6

⇒ f(h + 9) = 2h + 12

⇒ f(h + 9) = 2(h + 6)

and

g(h + 9) = (h + 9) – 2(h + 9)²

⇒ g(h + 9) = h + 9 – 2(h² + 81 + 18h)

⇒ g(h + 9) = h + 9 – 2h² + 162 + 36h

⇒ g(h + 9) = -2h² + 37h + 171

⇒ g(h + 9) = -(2h + 19)(h - 9)

Thus, the required value of each function is

f(h + 9) = 2(h + 6)

g(h + 9) = -(2h + 19)(h - 9)

Answer:

8.6

Step-by-step explanation:

There is an easier way which is finding the slope of the equation but I'm going to stick to distance formula(which is easier for me).

For this, you would have to know the distance formula which is

d=√(x2−x1)^2+(y2−y1)^2

Which simplifies into [tex]\sqrt{(7)^2 +(5)^2}[/tex] which you get from 6-(-1) and -2-(-7)

Further simplifies into [tex]\sqrt{49+25}[/tex]

=[tex]\sqrt{74}[/tex]

=8.602325

use the distance formula:

√ ( x2 - x1 )² + ( y2 - y1 )²

√ ( 6 - ( - 1 ) )² + ( - 2 - ( - 7 ) )²

√ ( 7 )² + ( 5 )²

√ 49 +25

√ 74

8.602325267

8.6 is the answer

Answer:

2.5π

Step-by-step explanation:

First, let's find the circumference of the circle. The circumference is equal to dπ, or the diameter times π.

Knowing the diameter is 10, we can easily find that the circumference is 10π.

10π is the entire circumference, but we only need 90° of the circle. If the whole circle is 360°, then that means the portion we need is 90°/360°, which is 1/4.

1/4 times 10π is equal to 2.5π.

2.5π is the arc length.

Answer:

$90

Step-by-step explanation:

Given data

Price= $900

Rate= 25%

Time= 8 years

Let us apply the compounding formula

A= P(1-r)^t    >>>>note that the negative sign is because of the depreciation

substitute

A= 900(1-0.25)^8

A= 900(0.75)^8

A= 900*0.100

A= $90

Hence the value of the car after 8 years will be  $90

Answer: Samsung Galaxy S12

Answer:

S₁₂ = 531440

Step-by-step explanation:

There is a common ratio between consecutive terms, that is

r = 6 ÷ 2 = 18 ÷ 6 = 3

This indicates the sequence is geometric with sum to n terms

[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex] ( r ≠ 1 )

where a is the first term and r the common ratio

Here a = 2 and r = 3 , then

S₁₂ = [tex]\frac{2(3^{12}-1) }{3-1}[/tex]

     = [tex]\frac{2(531441-1)}{2}[/tex]

     = 531441 - 1

     = 531440

Answer:

V = 900π ≈ 286.47 units³

Step-by-step explanation:

C = 2πr

12 = 2πr

r = 12/2π = 6/π

V = 2πr²h

V = π(6/π)²(25) = π(36/π²)(25)

V = 36/π(25) = 900/π ≈ 286.47

Answer:

218 cm²

Step-by-step explanation:

Can of soup has a radius of 3.4 centimeters. Can is 10.2 centimeters tall, what is the approximate area of the label that wraps around the can?

The formula to solve the above question is given as:

The curved or the lateral surface area of the cylinder = 2πrh

Where:

r = 3.4 cm

h = 10.2 cm

The curved or the lateral surface area of the cylinder = 2 × π × 3.4 cm × 10.2 cm

= 217.9 cm²

Therefore, the approximate area of the label that wraps around the can is

218 cm².

Answer: for -10 + 4 the answer is -6

for -7 - 11 the answer is -18

Step-by-step explanation:

For -10+4 all you do is start at -10 and go up 4 to -6 (-9, -8, -7, -6)

and for -7 - 11 you start at 7 and just go down (but the numbers get bigger) to -18 (-8, -9, -10, -11, -12, -13, -14, -15, -16, -17, -18)

it must be y=-5x+21

Step-by-step explanation:

lets type the equation in front of us and make it simple so we can deal with it

y-1=-5(x-4)

first thing you need to do is to remove those brackets by multiplying whats in the bracket by -5 like this

y-1=-5x+20             -5*x=-5,,  -5*-4=20 (note: when you multiply negative with

                                                               negative result is positive)

then add each side by 1 so it will be

y=-5x+21

Answer:

Step-by-step explanation:

The sum of the angles in a triangle is always 180 degrees.

40+3x+180-5x+10=180

-2x+50=0

-2x=-50

x=25

Again using the fact that the angles must have a sum of 180

40+3x+a=180

40+3(25)+a=180

40+75+a=180

a+115=180

a=65

So angle 1 is 65 degrees.

Answer:

  $283.53

Step-by-step explanation:

The compound interest formula is useful.

  A = P(1 +r/12)^(12t)

gives the amount A when principal P is invested at annual rate r compounded monthly for t years.

Using your values, this is ...

  A = $200(1 +0.07/12)^(12·5) ≈ $283.53

The investment would be worth $283.53 after 5 years.

Answer:

$280.51

Step-by-step explanation:

just took this

Answer:

We just need the equations to equal the same, which is y.

5+1.10x=y

3+1.50x=y

5+1.10x= 3+1.50x

Let's get x by itself by subtract 3 from both sides.

2+1.10x= 1.50x

Now subtract 1.10x from both sides.

2= 0.4x

Now divide each side by 0.4

5=X

So, at 5 games they're the same cost. Let's find the cost.

5+1.1(5)= 5+5.5=10.50

3+1.5(5)=3+7.5= 10.50

So, at 5 games, they are $10.50.

Hope this helps! :)

[tex]a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1[/tex]

Step-by-step explanation:

Given: The smaller branches spiral in the pattern [tex]\{2,3,5,8,...\}[/tex] from a larger limb.

To model: the tree growth with the Fibonacci sequence

Solution:

Take [tex]a_1=2[/tex]

Let [tex]a_n[/tex] denotes the [tex]n^{th}[/tex] term.

[tex]a_2=3=2+1=2+(2-1)=a_1+(2-1)\\a_3=5=3+2=3+(3-1)=a_2+(3-1)\\a_4=8=5+3=5+(4-1)=a_3+(4-1)[/tex]

So,

[tex]a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1[/tex]

Answer:

Yes.

Step-by-step explanation:

The pattern in which the branches are growing off the limb is {1, 1, 2, 3, 5, 8, …}, meaning you can use the model with tree growth.

Answer:

The height is 4 cm

Step-by-step explanation:

V = (pie) x radius² x height

615.44 cm³ = (3.14) x 7² x h

h = 615.44 cm³/(3.14 x 49)

h = 615.44 cm³/153.86

h = 4 cm²
