What is 1 and 7/18 written as an improper fraction?

Answer:

D) $0.15/hr

Step-by-step explanation:

Divide 1.5 by 10 and you get 0.15, check your work by dividing 3 by 20=0.15, you divide the numbers in which are a line, for example look at the cost 3 and hours used 20, (if that makes sense)

Answer:

C

Step-by-step explanation:

because The graph of which quadratic function has roots of 7 and 3 and passes through (2, 10), so therefore its C

The equation f(x) = 2x² -20x +42 and the function has minimum at x=5 which is f(5) = -8 option (C) is correct.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

Part A)

The quadratic function has roots of 7 and 3

f(x) = (x - 7)(x - 3)

f(x) = x² -3x -7x +21

f(x) = x² -10x +21

Multiply by:

f(x) = 2x² -20x +42

Plug (2, 10)

10 = 8 - 40 +42 = 10

Part B) From the graph, the function has minimum at x = 5

f(5) = -8

Thus, the equation f(x) = 2x² -20x +42 and the function has minimum at x=5 which is f(5) = -8

Answer:

The awnswer is D. 54.3in^3

Step-by-step explanation:

The amount of snow that can be placed on this globe will be 23.1 inch³.

Globe is a spherical 3d element that has a radius let R then the volume of that sphere will be 4/3 π R³.

Given a globe wide 4.7 inches means it is the diameter of the globe.

The radius of the globe = dia/2.

Radius = 2.35 inch.

Volume of globe(amount of snow) = 4/3 π (2.35)³= 23.1 inch³

so the amount of snow needed will be 23.1 inch³.

Answer:

[tex] \displaystyle \frac{1}{12} \ln( |{4x}^{ 3} + 9|) + \rm C[/tex]

Step-by-step explanation:

we would like to integrate the following indefinite integral:

[tex] \displaystyle \int \frac{ {x}^{2} }{4 {x}^{3} + 9} dx[/tex]

in order to integrate it we can consider using u-substitution also known as the reverse chain rule and integration by substitution as well

we know that we can use u-substitution if the integral is in the following form

[tex] \displaystyle \int f(g(x))g'(x)dx[/tex]

since our Integral is very close to the form we can use it

let our u and du be 4x³+9 and 12x²dx so that we can transform the Integral

as we don't have 12x² we need a little bit rearrangement

multiply both Integral and integrand by 1/12 and 12:

[tex] \displaystyle \frac{1}{12} \int \frac{ 12{x}^{2} }{4 {x}^{3} + 9} dx[/tex]

apply substitution:

[tex] \displaystyle \frac{1}{12} \int \frac{ 1}{u} du[/tex]

recall Integration rule:

[tex] \displaystyle \frac{1}{12} \ln(|u|) [/tex]

back-substitute:

[tex] \displaystyle \frac{1}{12} \ln( |{4x}^{ 3} + 9|) [/tex]

finally we of course have to add constant of integration:

[tex] \displaystyle \frac{1}{12} \ln( |{4x}^{ 3} + 9|) + \rm C[/tex]

and we are done!

64  - 16 = 48

49 = 16 x 3

Answer:

Step-by-step explanation:

Problem 1

g(-23) = 3

g(0) = 5

2 = g(10)

1 = g(34)

Problem 2

No, because g(x) = f(-x).  For g(x) to inverse of f(x), g(f(x)) = x

Problem 3

tan(50) = 1.19

Height of statue = 250*1.19 - 150

= 147.9 ft

Problem 4

cosθ = 9/12

θ = 41.41 deg.

Answer:

Step-by-step explanation:

g(x) is inverse of f(x)

so g(f(x))=x

g(-23)=3

g(0)=5

g(10)=2

g((34)=1

no, it is an inverse

4 inverse fn, g(r(x))=x

but here g(x)=r(-x)

so g(r(x))=r(-r(x)) n NOT =x

pedestal + statue = 250*tan(50degree) = 297.94

statue ht = 297.94-150 = 147.94 ft

cos(theta) = 9/12

theta = 41.41 deg.

Answer:

The distance between the two points is [tex]\sqrt 53[/tex]

Step-by-step explanation:

First you find the distance between the x values which is 2 units and then you find the distance between the two y values which is 7 units. Then you use the pythagorean theorem to find the distance between the two points. Since the distance between the x values is 2 and the distance between the y values is 7 then you do 2²+7² and you get the square root of 53 since the pythagorean theorem equation is a²+b²=c².

Answer:

7. D. Obtuse

8. D. 5

9. C. 117°

Step-by-step explanation:

Step 1: Define.

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

Step 2: Solve.

7. The angle presented is an obtuse angle because it is more than 90°, but less than 180°.

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

Step 2 continued: Solve.

8. 140° and 8x° are supplementary angles; this means both angles have a sum of 180°.

[tex]140 + 8x = 180[/tex]

The first step to finding 'x' is to subtract 140 from 140 and 180.

[tex]140 - 140 = 0[/tex] (cancels itself out)

[tex]180 - 140 = 40.[/tex]

Now we are left with:

[tex]8x=40.\\[/tex]

The last step to solving this is dividing 40 by by the coefficient.

[tex]40/8=5[/tex]

[tex]x=5.[/tex]

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

Step 2 continued: Solve.

9. As I mentioned before, supplementary angles are two angles that have a sum of 180°.

If angle 1 is 63, then angle 2 is..

[tex]180 - 63 = 117[/tex]

Angle 2 is 117°.

Answer:

0.80X = Y

Step-by-step explanation:

Given that a store sells beans for 80 cent per pound to determine the equation that graphs the proportional relationship that gives the cost Y in dollars of buying X pounds of beans, the following mathematical reasoning must be performed:

Cost of each pound of beans = 0.80

0.80 x quantity (X) = Total cost (Y)

0.80X = Y

Thus, if 5 pounds of beans were purchased, the equation would operate as follows:

0.80 x 5 = Y

4 = Y

Answer:

400 - 2 (24 months) = $352

Step-by-step explanation:

The balance in Maas account after two years will be $352.

Mass has a bank account with less than $ 400 in it. He pays charges of $ 2 per month if account has less balance than $500.

We have to find out that if he doesn't deposit or withdraws any amount , what will be balance of his account after 2 years ?

What will be the value if 2 times of 400 is added to 2 times of 400 ?

The value will be 1600.

We know that no. of months in 1 year = 12 months

No. of months in 2 years = 24 months

As , bank charges $2 per month if the balance is less than $500.

⇒ for 24 months the charges will be ;

    = 24 × 2 = $48

The balance in Maas account after 2 years will be

  $ 400 - $ 48 = $ 352.

Thus, the balance in Maas account after two years will be $352.
