Answer:

f(x) = 19x/5+4

Step-by-step explanation:

f(0) = 4,f(5)=19

[f(x) - 4]/[x-0] = (19-0)/(5-0)

f(x) = 19x/5+4

Answer:

92°

Step-by-step explanation:

∠C=180-140=40

∠A+∠B+∠C=180

40+2X+X+2=180

X=46

∠B=46*2=92°

Answer: 92 degrees

Step-by-step explanation:

The exterior angle measuring 140 is equal to the sum of the two remote interior angles.

(X+2) + (2x) = 140. Combine like terms.

2 + 3x = 140. Subtract 2 from both sides.

3x = 138. Divide both sides by 3.

X = 46

Angle b = 2x. Substitute 46 in for x.

Angle b = 2(46)

Angle b = 92

Answer:

angle S    100  option C

Step-by-step explanation:

P and S are consecutive angles

Interior angles of a parallelogram

1. Opposite angles are congruent

2. Consecutive angles are supplementary (They add to 180 )

(2x+20) + (3x+10) = 180

5x+30 = 180

5x = 150

x= 30

angle S      3x30 +10 =

                   90 +10 =   100

The other angle P      2x30 +20 = 60 +20 = 80

  100 +80 = 180

Answer:

The height of the tree is approximately 71.5 feet

Step-by-step explanation:

The given parameters are;

The angle of elevation to see the top pf the tree = 50°

The distance Peggy is laying from the base of the tree = 50 ft.

In order to answer the question using trigonometric ratio, we assume that the angle the tree makes with the ground is 90° that is the tree is perpendicular to the ground

Therefore, the line of sight to the top of the tree,  the height of the tree, and the distance from the base of the tree where Peggy is laying, forms a right triangle

Let, 's', represent the line of sight to the top of the tree, let 'h', represent the height of the tree, and let, 'd', represent the distance from the base of the tree where Peggy is laying

The third angle, θ, of the right triangle opposite 'd' is given by angle sum theorem of a triangle as follows;

θ = 180° - 90° - 50° = 40°

θ = 40°

By sine rule we have;

h/sin(50°) = d/(sin θ)

∴ h/sin(50°) = 60 ft./(sin 40°)

h = sin(50°) × 60 ft./(sin 40°) = 71.5052156 ft.

∴ The height of the tree, h ≈ 71.5 ft. by rounding to the nearest tenth

Answer:

1 + 8y + 28y² + 56y³ + 70[tex]y^{4}[/tex] + 56[tex]y^{5}[/tex] + 28[tex]y^{6}[/tex] + 8[tex]y^{7}[/tex] + [tex]y^{8}[/tex]

Step-by-step explanation:

For the expansion of [tex](1+y)^{8}[/tex]

Using the row of Pascal's triangle for n = 8 , that is the coefficients are

1  8  28  56  70  56  28  8  1

Decreasing powers of 1 from [tex]1^{8}[/tex] to [tex]1^{0}[/tex]

Increasing powers of y from [tex]y^{0}[/tex] to [tex]y^{8}[/tex]

Then

[tex](1+y)^{8}[/tex]

= 1 . [tex]1^{8}[/tex].[tex]y^{0}[/tex] + 8. [tex]1^{7}[/tex].[tex]y^{1}[/tex] + 28. [tex]1^{6}[/tex].y² + 56. [tex]1^{5}[/tex].y³ + 70.

Answer:

about 3.2 gallons. (3.2, 12)

Step-by-step explanation:

If gas costs $3.75 per gallon and Berto has $12, then he can purchase 12/3.75 gallons. This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12)

about 3.2 gallons. (3.2, 12)

Answer:

C

1. homework

2. research outline

3. test

4. essay

Step-by-step explanation:

The tasks will be prioritized based on the ones with the closest date to today.

Her homework due tomorrow, therefore it is the first priority.

Her research outline due by the end of the week, therefore it is the second priority.

She has a test next week, and therefore it is the third priority.

Then finally, in 2 weeks, she has an essay and as such it should be the fourth priority.

The only option that has these tasks arranged in the correct order of priority based on the most important tasks as I have listed is Option C.

Step-by-step explanation:

Answer:

65

Step-by-step explanation:

2x + 25 + 25 = 180

2x + 50 = 180

2x = 180 - 50

2x = 130

2x / 2 = 130 / 2

x = 65

Answer:

32 Kilometers

Step-by-step explanation:

A Car travels 80 Kilometers in 2 and Half hours.

1 Hour =60 minutes, 2 & Half hours= 2.5*60= 150 minutes

Kilometers travelled by Car in a hour= 80/150*60= 32 Kilometers

Answer:

let X interchange y and vice versa

X= 2x+3

carry across +3

X-3=2X

carry across 2 (2X is 2 multiple by X when carried across the sign change to division)

so X-3 divided by 2 is = X

Answer:

1 : 3.375

Step-by-step explanation:

divide both sides by 32 to get the above answer

The simple ratio of 32kg to 108kg​ is 8 : 27.

In its most basic form, a ratio is a comparison between two comparable quantities.

There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.

If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.

Given, Two similar quantities one weighs 32 kgs and the other weighs

108 kgs.

Therefore, The ratio between them is 32 : 108.

= 16 : 54.

= 8 : 27.

N in the equation is the number of times it compounds in a year. Since it is compounded yearly n = 1.

A = 1000( 1+ 0.08/1)^(7x1)

A = 1000(1.08)^7

A = $1,713.82

Answer: you added 6 liters of juice

Step-by-step explanation:

You have 10 liters of a juice blend that is 60% juice. How many liters of pure juice need to be added in order to make a blend that is 75% juice?

Ten liters of a juice blend at 60% juice means you also have ten liters of a juice blend at 40% water. 10 x .40 yields 4 liters of water in your blend.

A juice blend of 75% has a water content of 25%. So the same 4 liters of water must represent 25% of the blend after adding more juice.

4/.25 = 16 liters. 16 x .75 = 12.

12 + 4 = 16.

That means after adding your juice you will have 16 liters of blend at 75% juice.

You originally had 10 liters at 60% and now you have 16 liters at 75% . Subtracting 10 from 16 means you added 6 liters of juice.
