How many hours in 20 days

Answer:

-4

Step-by-step explanation:

The remainder when P(x) is divided by (x + 2) is P(-2) which is - 4

Answer:

y = -3 (you have to draw an horizontal line that passes for the point (0,-3)

Step-by-step explanation:

We have to find the middle points of the segments that unite the corrispettive points.

We are lucky because the images of the points have the same x coordinate of the original ones, so we have just to find the y coordinates.

Segment CC‘

(y1 + y2)/2 = (-1-5)/2 = -3

Segment AA’

(0-6)/2 = -3

Segmet BB’

(1-7)/2 = -3

Segment DD’

(1-7)/2 = -3

In conclusion we can say that the points of the reflection have all the y coordinate equal to -3.

the line is horizontal and its equation is : y = -3

Answer:

y=3x-2

Step-by-step explanation:

The slope of the equation is (-2-(-5))/(0-(-1))=3. The y intercept is - 2. So y=3x-2

Answer:

Base area=5*12=60

Height is 4

Perimeter or the base is 2*(12+5)=34

Surface area is 2B+Ph=120+136=256

Answer:

A. 24

Step-by-step explanation:

Five and above rounds up

so 25,26,27,28,29 rounds up to 30

We leave it alone when 4 or less

34,33,32,31,30 remains at 30

24 would not round to 30

The approximate area of the shaded region is 2794 m². The correct option is the first option 2794 square meters

From the question, we are to determine the approximate area of the shaded region

The area of the shaded region = Area of the triangle - Area of the circle

Area of triangle = 1/2 × base × height

Area of the triangle = 1/2 × 90 × 90

Area of the triangle = 4050 m²

Area of a circle = πr²

Where r is the radius

In the diagram,

Diameter = 40 m

∴ Radius = 40/2 = 20 m

Thus,

Area of the circle = π × 20²

Area of the circle = 3.14 × 400

Area of the circle = 1256 m²

Therefore,

The area of the shaded region = 4050 m² - 1256 m²

The area of the shaded region = 2794 m²

Hence,

The darkened area covers about 2794 m²

Answer:

Step-by-step explanation:

A(1) is the amount after 1 decade.

A(0.1) is the amount after 1  year.

Every year, the amount of CO₂ increases by a factor of 1.06^(0.1) ≅ 1.0058

Answer:

150 Newtons

Step-by-step explanation:

Given

[tex]t = \sqrt{\frac{4\pi^2mr}{F}}[/tex]

[tex]t = 12[/tex]

[tex]r =6.5[/tex]

[tex]\pi = 3.14[/tex]

[tex]m = 84.4[/tex]

See attachment

Required

Find F

We have:

[tex]t = \sqrt{\frac{4\pi^2mr}{F}}[/tex]

Square both sides

[tex]t^2 = \frac{4\pi^2mr}{F}[/tex]

Multiply both sides by F

[tex]Ft^2 = 4\pi^2mr[/tex]

Divide both sides by [tex]t^2[/tex]

[tex]F = \frac{4\pi^2mr}{t^2}[/tex]

Substitute known values

[tex]F = \frac{4*3.14^2*84.4*6.5}{12^2}[/tex]

[tex]F = \frac{21635.90624}{144}[/tex]

[tex]F = 150.249348889[/tex]

[tex]F = 150N[/tex]

Answer:

d = 6

Step-by-step explanation:

10 - d = 34 - 5d

add d to both sides to make all the d's on one side

10 = 34 - 4d

subtract 34 from both sides to isolate the d and its coefficient

-24 = -4d

divide both sides by -4 to isolate d

d = 6

Step-by-step explanation:

I'll be referring to each of these numbers as x and y.

x + y = 4

(x^2) + (y^2) - 3(x)(y) = 76

x = 4 - y

(4 - y)^2 + (y^2) - 3(4 - y)(y) = 76

(4 - y)(4 - y) + y^2 - (3y)(4 - y) = 76

16 - 4y - 4y + y^2 + y^2 - 12y + 3y^2 = 76

16 - 20y + 5y^2 = 76

5y^2 - 20y - 60 = 0

y^2 - 4y - 12y = 0

(y - 6)(y + 2) = 0

y = 6 or -2

x = 4 - 6 = -2

x = 4 - - 2 = 6

As you can see, we got the same numbers for both x and y, -2 and 6. Therefore, the two numbers are -2 and 6. But, we can check our work to ensure that the answer is correct.

x = -2

y = 6

6 - 2 = 4

4 = 4

(-2)^2 + (6^2) - 3(-2)(6) = 76

4 + 36 - 3(-12) = 76

40 + 36 = 76

76 = 76

Hope this helps!

Answer:

y = [tex]\frac{20}{9}[/tex]

Step-by-step explanation:

Since the figures are similar then the corresponding sides are in proportion, that is

[tex]\frac{JH}{PQ}[/tex] = [tex]\frac{FM}{ST}[/tex] , substitute values

[tex]\frac{6}{4}[/tex] = [tex]\frac{7}{3y-2}[/tex] ( cross- multiply )

6(3y - 2) = 28

18y - 12 = 28 ( add 12 to both sides )

18y = 40 ( divide both sides by 18 )

y = [tex]\frac{40}{18}[/tex] = [tex]\frac{20}{9}[/tex]

Answer:

20/9

Step-by-step explanation:

since the 2 are similar,

JH/PQ = FM/ST

6/4 = 7/(3y-2)

6(3y-2) = 7*4

18y-12=28

18y = 40

y = 40/18 = 20/9 = 2 2/9

Answer:

[tex]\frac{9}{5}[/tex]

Step-by-step explanation:

[tex]\frac{4}{9}[/tex] × [tex]\frac{45}{36}[/tex]

[tex]\frac{5}{9}[/tex]

Given a number n then its reciprocal is [tex]\frac{1}{n}[/tex]

Then the reciprocal of [tex]\frac{5}{9}[/tex] is

[tex]\frac{1}{\frac{5}{9} }[/tex] = [tex]\frac{9}{5}[/tex]

Step-by-step explanation:

It is convenient to let a graphing calculator show the answers to these questions.

The exponential equation modelling the growth will be of the form ...

  f(x) = (initial value) × (1 +growth rate)^x

Richland's GDP/person can be modeled by r(x) = 10·1.01^x

Poorland's GCP/person can be modeled by p(x) = 5·1.03^x

The attached graph shows values for x=5, 10 and r(x)=p(x).

It will take about 35.3 years for Poorland to catch up.

Answer:

Rate of Return is 14.8%

Step-by-step explanation:

We know that 20 shares of Stock are purchased for $30 per share.

This gives us a total value of: 20 × 30 = $600.

Now, the shares are sold for $710 with a commission sale of $6. This means the final money going to the seller is; 710 – 6 = $704.

Thus, the rate of return percentage is = (704 – 600)/704) × 100% = 14.7727%

To the nearest tenth gives us 14.8%

Answer:

Step-by-step explanation:

Let x represent the amount invested at 13%. Then (3x+199) is the amount invested at 12%. The total interest earned in 1 year is ...

  (13%)(x) +(12%)(3x+199) = 1561.50

  0.49x +23.88 = 1561.50 . . . . simplify

  0.49x = 1537.62 . . . . . . . . . . subtract 23.88

  x = 3138 . . . . . . . . . . . . . . . . divide by 0.49

  3x+199 = 9613

$3138 was invested at 13%; $9613 was invested at 12%.
