Pls help me with this question!!

Answer:

Step-by-step explanation:

-3-5=-8

-11-(-3)=-11+3=-8

-19-(-11)=-19+11=-8

it is an A.P. and c.d.=-8

so nth term is

an=a1+(n-1)d

an=5-(n-1)(-8)

an=5+8n-8

an=8n-3

Answer:

Step-by-step explanation:

1/4 : 2 * 1/4 = 6 : x

0.25 : 2/4 = 6 : x

0.25 : 1/2 = 6 : x

0.25 : 0.5 = 6 : x

0.5 = 6 : x

x = 6 : 0.5

x = 12

Answer:

D. 8

Step-by-step explanation:

f(3) = 2·3 - 2 = 4

2·f(3) = 2·4 = 8

Answer:

A  8º

B  76º

C  74º

D  128º

Step-by-step explanation:

The sum of the angles is 360

(3x + 10) + (3x + 4) + (x + 50) + (5x + 8) = 360

Combine like terms

12x + 72 = 360

Subtract 72 from both sides

12x = 288

Divide both sides by 12

x = 24

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

A (3x+10) = 3*24 + 10 = 82

B (3x+4) = 3*24 + 4 = 76

C (x+50) =  24 + 50 = 74

D (5x+8) = 5*24 + 8 = 128

Based on the centroid theorem, the value of x is: 2.5.

The centroid theorem states that, the centroid of a triangle equals two-third of the distance from each midpoint of a triangle to each vertex.

Given:

BD = 4x + 5

BF = 9x

Thus:

BD = 2/3(BF)

4x + 5 = 2/3(9x)

4x + 5 = 6x

4x - 6x = -5

-2x = -5

x = 5/2

x = 2.5

Therefore, based on the centroid theorem, the value of x is: 2.5.

Answer:

Step-by-step explanation:

So the sum of 128 and x+10 is on a straight line which is 180º right?, so:

x + 10 + 128 = 180

x = 180 - 128 - 10

x = 42º

Answer:

42

Step-by-step explanation:

x +10 +128 = 180   {Linear pair}

x  + 138 = 180

x = 180 - 138

x = 42

Step-by-step explanation:

these are all isoceles triangles (2 sides are equal). that also means that the 2 angles at the end of the equal sides are equal.

so, the angle at F and H are both 65°.

the angle at J = 2×65 = 130°.

the angle at G = 2×(180 - 65 - 65) = 2×50 = 100°.

remember, the sum of all angles in a triangle is always 180°.

so many ways now to get y.

let's use the triangle GH and crossing point of diagonals (there is a right angle).

y = 180 - G/2 - 90 = 180 - 50 - 90 = 40°

Answer:

32

Step-by-step explanation:

work backwards, 19-11=8 then x 4 makes 32.

Answer:

32

Step-by-step explanation:

Let the number be 'x'

[tex]\dfrac{x}{4}+11=19[/tex]

Subtract 11 from both sides

[tex]\dfrac{x}{4}=19 - 11\\\\\dfrac{x}{4}=8\\[/tex]

Multiply both sides by 4

x = 8*4

x = 32

Fyi: If you want answers to something I don't think threating to reporting people trying to help you is a good idea.

The Domain is {0, 1, 2, 3, 4} and Range is { 1600, 1900, 2200, 2500, 2800}.

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Given:

He is paid a salary of $1600 per month plus $300 for each car that he sells.

and,  His salary can be modeled by the equation f(x) = 300x + 1600

The Domain can be taken as

x= 0, 1, 2, 3, 4

and, the range is

f(0)= 1600

f(1)= 1900

f(2)= 2200

f(3)= 2500

f(4)= 2800

Step-by-step explanation:

the perimeter is easy.

it is an isoceles triangle, that means both sides are equally long (10 units).

the length of the baseline we can read directly off the coordinates of P and Q.

both are on the same horizontal grid line y = 1. so, the difference in x is their distance : 8 - -8 = 8+8 = 16

so, the perimeter is 10 + 10 + 16 = 36 units.

now, for k :

k is the height of the triangle + 1 (as the baseline is at y=1 and not at 0).

we can get the height by using Pythagoras :

c² = a² + b²

c is the Hypotenuse (the baseline) of the dude opposite of the 90° angle.

the triangle we use for this is

PR, half of PQ and the height of the main triangle, with PR being the Hypotenuse.

so,

10² = (16/2)² + height² = 8² + height²

height² = 10² - 8² = 100 - 64 = 36

height = 6

therefore, k = 6 + 1 = 7

Parentheses, Exponents, Multiplication and Division, Addition and Subtraction (From left to right)

M=Multiplication

D=Division

Multiplication is done before division.

So, multiply 1.21*2 for the first problem, and 1.20*2 for the other 2 problems.

1.

24/(1.21)2 becomes 24/2.42

24/2.42= 9.9173553719 (or 9.92 rounded, or 9.9)

2.

29/(1.20)2 becomes 29/2.4

29/2.4= 12.0833333333 (or 12.08 rounded, or 12.1)

3.

40/(1.20)2 becomes 40/2.4

40/2.4= 16.6666666667 (or 16.7 rounded)

I am not sure if you have to round your answers up, so I provided those answers as well in case.

The length of the wire AC is 61 meters.

Pythagoras theorem is used to show the relationship between the sides of a right angled triangle.

We can find the length of wire AC using Pythagoras theorem:

AC² = 60² + (66 - 55)²

AC² = 60² + 11²

AC² = 3721

AC = 61 meter

The length of the wire AC is 61 meters.

Answer: Slope (M) = 7.5

Y-intercept (B) = 0

Step-by-step explanation:

For the slope, the first step is to find your "pretty points" (spots on the slope that hit the corner perfectly, like (0, 0) or (2, 15).

Now, make a triangle with the two points. Count the amount of squares on both. This will give you 3 and 4, but when taking the units into consideration, 15 and 2. The last step is to divide 15 and 2 which gives you 7.5. I would recommend writing both 15/2 and 7.5 but it's up to you.

The Y-intercept is just the spot where the Y is 0, or where the line touches the Y-axis. This is at the origin, where both X and Y are 0, so your Y-intercept is 0.
