Answer:

[tex]40x^{4}[/tex] - [tex]9x^{3}[/tex] + [tex]46x^{2}[/tex] + 6x + 16

Step-by-step explanation:

Answer:

y = 0.25x - 9.5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 0.25 , then

y = 0.25x + c ← is the partial equation

To find c substitute (6, - 8) into the partial equation

- 8 = 1.5 + c ⇒ c = - 8 - 1.5 = - 9.5

y = 0.25x - 9.5 ← equation of line

Answer:

Step-by-step explanation:

The equation in point-slope form:

y = 0.25(x - 6) - 8

y = 0.25x - 1.5 - 8

y = 0.25x - 9.5        ←   slope-intercept form

Answer:

$603.04

Step-by-step explanation:

The Compound Amout formula is A = P(1 + r)^t, where:

P is the principal (initial deposit), r is the annual interest rate as a decimal fraction, and t is the time period in years.

In this particular case, the Compound Amount is:

A  = ($450)(1 + 0. 05)^6 = ($450)(1.34) = $603.04

Answer:

1 6/8 cups of flour

Step-by-step explanation:

Just subtract 2 1/8 from 3 7/8

Answer:

1344

Step-by-step explanation:

100cm = 1 m

Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth =  320 x 280 = 89,600m²

Area of a square = length² = 10cm² = 100cm²

Number of tiles that would be needed = area of floor / area of square

89,600cm² / 100cm² = 896

Cost of one tile = rs 150 / 100 = 1.5

Cost of 896 tiles = 1.5 x 896 = 1344

Answer:

3.0 inches

Step-by-step explanation:

The formula for the volume of a sphere is

V = 4/3 × π × r³

V = 113.04 cubic inches

To find r

r = (3V/4π)⅓

r = (3 × 113.04/4 × π )⅓

r = 3.0 inches

The radius of one flask = 3.0 inches

Option A is correct

Answer:

(16×16) +(32×8)

256+256

512m²

Answer:

$108

Step-by-step explanation:

The computation of the total profit is shown below:

Given that

1 box = $12

18 boxes = 12×18 = $216

So

Total = 18×65 = 1170 pens

Now Cost price, Cp = $216

Also,

3 = $1

So,

= 378 ÷ 3

= $126

Now

= 1170-378

= 792 pens remaining

4 = $1

So,

792

= 792 ÷ 4

= $198

Now

Total selling price, sp = 126+198 = $324

So finally

Profit = Sp - Cp

= $324 - $216

= $108

Answer:

NM = 15

Step-by-step explanation:

Given a secant and a tangent from an external point to the circle, then

The square of the measure of the tangent is equal to the product of the secant's external part and the entire secant, that is

(x + 3)² = (x - 3)(x - 3 + 16)

(x + 3)² = (x - 3)(x + 13) ← expand both sides using FOIL

x² + 6x + 9 = x² + 10x - 39 ( subtract x² + 10x from both sides )

- 4x + 9 = - 39 ( subtract 9 from both sides )

- 4x = - 48 ( divide both sides by - 4 )

x = 12

Then

NM = x + 3 = 12 + 3 = 15

Answer:

D

Step-by-step explanation:

if x= number of hours replace the x by 9

so you have 5×(1.50)^9+10=

5×(192.21)+10 = 202.21 so 202 will be nearest whole number

Answer:

y - 8 = 4(x - 2)

Step-by-step explanation:

Note that as we increase any x value by 1, the corresponding y value increases by 4.  Thus, the slope is 4.

Using the slope-intercept formula, we get:

y - 8 = 4(x - 2)

Check:  If x = 5, does this formula result in y = 20?

y = 8 + 4(x - 2) with x = 5 comes out to y = 8 + 4(3)  =  8 + 12 = 20.  YES

Answer:

14.93°

Step-by-step explanation:

Using trigonometry :

From the diagram attached :

Angle of elevation = x

To obtain the value of x

Tan x = opposite / Adjacent

Tan x = 8 / 30

Tan x = 0.266666

x = tan^-1(0.26666)

x = 14.93°

Therefore, the angle of elevation is 14.93°

Answer:

62/100= 31/50

45/100= 9/20

Step-by-step explanation:

Divide 62 and 100 by two to simplify

Divide 45 and 100 by 5 to simplify

Answer:

62/100 = 31/50

45/100 = 9/20

Step-by-step explanation:

62 and 100 have a greatest common factor of 2. We can use this to break the fraction 62/100 apart:

[tex]\dfrac{62}{100}=\dfrac{2\times31}{2\times50}=\dfrac{2}{2}\times\dfrac{31}{50}=\dfrac{31}{50}[/tex]

We can do the same to simplify 45/100. The greatest common factor of 45 and 100 is 5, so following the same process:

[tex]\dfrac{45}{100}=\dfrac{5\times9}{5\times20}=\dfrac{5}{5}\times\dfrac{9}{20}=\dfrac{9}{20}[/tex]

Answer:

22

Step-by-step explanation:

Hey There!

So if you didn't know angle H is a right angle. So we are given two angles and they want us to find the missing angle

Remember all of the angles of a triangle add up to equal 180

so we subtract the given angles from 180 to find the missing angle

180-90-68=22

so we can conclude that angle G = 22

Answer:

x₂ = - 3

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to [tex]\frac{5}{6}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (9, 9) and (x₂, y₂ ) = (x₂, - 1)

m = [tex]\frac{-1-9}{x_{2}-9 }[/tex] , that is

[tex]\frac{-10}{x_{2}-9 }[/tex] = [tex]\frac{5}{6}[/tex] ( cross- multiply )

5(x₂ - 9) = - 60 ( divide both sides by 5 )

x₂ - 9 = - 12 ( add 9 to both sides )

x₂ = - 3

Answer:

The answer is 75

Step-by-step explanation:

5(3+12)

15+60

75

Answer:

Step-by-step explanation:

5(3+12) = 5×15 = 75

Answer:

Function 1:

We have 3x + 5, so we plug in 3 for x to get 9 + 5 = [tex]\boxed{14}[/tex]

Function 2:

We have [tex]\frac{1}{2}x^{2} - 1.5[/tex] so we have 4.5 - 1.5 = [tex]\boxed{3}[/tex]

Function 3:

We have [tex]\frac{3}{2x}[/tex] which becomes [tex]\frac{3}{6} = \boxed{\frac{1}{2}}[/tex].
