Answer:

[tex] \huge \boxed{f(15) = 152 }[/tex]

Step-by-step explanation:

[tex]f(x) = 15 {x}^{2} - x + 20[/tex]

To find f(3) , substitute the value of x that's 3 into f(x). That is for every x in f(x) replace it with 3.

We have

[tex]f(15) = 15( {3})^{2} - 3 + 20 \\ \: \: = 15(9) + 17 \\ = 135 + 17 \: \\ = 152 \: \: \: \: \: \: \: \: \: \: [/tex]

We have the final answer as

[tex]f(15) = 152 [/tex]

Step-by-step explanation:

$282 = $128 + 14w

$282 -$128 = $14w

            $154 = $14w

                14 =     14

                 11 = w

Step-by-step explanation:

Answer:

Quarters = q = 200

Dimes = d = 756

Step-by-step explanation:

Let

Dimes = d

Quarter = q

Value of each Dime = 0.10

Value of each Quarter = 0.25

d + q = 956 (1)

0.1d + 0.25q = $125.60 (2)

From (1)

d = 956 - q

Substitute d = 956 - q into (2)

0.1d + 0.25q = $125.60

0.1(956 - q) + 0.25q = $125.60

95.6 - 0.1q + 0.25q = $125.60

- 0.1q + 0.25q = 125.60 - 95.6

0.15q = 30

Divide both sides by 0.15

q = 30 / 0.15

= 200

q = 200

Substitute q = 200 into (1)

d + q = 956

d + 200 = 956

d = 956 - 200

= 756

d = 756

Therefore,

Quarters = q = 200

Dimes = d = 756

Answer:

Each side is 15 ft

Step-by-step explanation:

The area of a square is given by

A = s^2 where s is the side length

225 ft^2 = s^2

Take the square root of each side

sqrt ( 225 ft^2) = sqrt ( s^2)

15 ft = s

Each side is 15 ft

Answer:

The answer is 2

Step-by-step explanation:

Find the diagram to the question attached.

From the diagram, we are given the following dimension for one of the beds;

Length = 16cm

Width = 8cm

If the scale from his drawing to the actual garden is 2 cm for every 1 ft, then on converting to feet;

2cm = 1ft

16cm = x fr

cross multiply

2x = 16

x = 8ft

Hence 16cm = 8ft (based on the scale)

Similarly:

2cm = 1ft

8cm = x fr

cross multiply

2x = 8

x = 4ft

Area of the garden bed (in feet) = Length * Width

Area of the garden bed = 8ft * 4ft

Area of the garden bed = 32ft²

Hence the actual area of one of the garden beds is 32ft². We need to find 2 things fir us to get the required answer. First is the length of the bed in feet and the second is the width of the bed in feet.

Answer:

15x^3y+6x^2y^2+9xy^3

Answer:

-8

Step-by-step explanation:

We can use the formula [ y2-y1/x2-x1 ] to solve.

-4-4/2-1

-8/1

-8

Best of Luck!

First of all, Let's find the slope because we need it on the formula for finding the y-intercept.

m = y2 - y1 / x2 - x1

From the points given in the question,

x1 = 1

x2 = 2

y1 = 4

y2 = -4

Plugging in the above formula,

➝ m = -4 - 4 / 2 - 1

➝ m = -8 / 1

➝ m = -8

Now finding the y-intercept[tex]:[/tex]

➝ y = mx + b

And if we put in the values from our first point (1, 4) we get

➝ 1 = -8 (4) + b

➝ 1 = -32 + b

➝ b = 1 + 32

➝ b = 33

Required equation of the line:

➝ y = -8x + 33

Answer:

The $3 per video game with $50 membership is more economically if you rent at least 11 games or more per year

Step-by-step explanation:

there are 365 days in a year

3 x 365 = 1095

1095 + 50 = $1145 (Cost per year)

8 x 365 = $2920 (Free Membership) cost per year

If you only rent 10 video games per year, they equals the same amount

$3 x 10 (games) = $30 Then $30 + $50 (Member Fee) = $80

$8 x 10 (games) = $80 for 10 games rental

If they rent 11 games or more per year, then the $3 rental is more economical.

$3 x 11 = $33; $33 + 50 = $83

$8 x 11 = $88

Answer:

Jessie hiked at a constant rate of 3 miles/hour

Step-by-step explanation:

Constant rate can also be called speed

The formula for constant rate /Speed = Distance (miles)/ time in hours

Distance = 1 mile

Time = 20 minutes

Converting to hours

60 minutes = 1 hour

20 minutes =

20/60

= 0.3333333333hour

Constant rate = 1mile/0.3333333333 hour

= 3.0000000003

= 3 miles/hour

Answer:

20 = 6m  or  m = 20/6 = 10/3

Step-by-step explanation:

Let's say Samantha has s marbles and Paul has m marbles.

We know that s = 20 and that Samantha has 6 times as many marbles as Paul. This means s = 6m.

Substitute 20 in for s:

20 = 6m

m = 20/6

Thus, the equation is m = 20/6.

Answer:

20 = 6m  or  m = 20/6 = 10/3

Step-by-step explanation:

[tex]lim \frac{ \sin(x) }{x} = 1 \\ [/tex]

It is true only whenever x tends to 0(zero)

it is not importent that x be in radian or in degree.

Answer:

The following property: If a = b and b = c, then a = c. One of the equivalence properties of equality. Note: This is a property of equality and inequalities.

Congruent Angles have the same angle (in degrees or radians). That is all. These angles are congruent. They don't have to point in the same direction. They don't have to be on similar sized lines.

The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.Jan 4, 2016

The (interior) bisector of an angle, also called the internal angle bisector (Kimberling 1998, pp. 11-12), is the line or line segment that divides the angle into two equal parts. The angle bisectors meet at the incenter.
