Answer:

the answer is A. 99 degrees because 81 + 18 = 99

Answer:

99°

Step-by-step explanation:

=====================================================

Work Shown:

Plug in n = 1 to find the next term

f(n+1) = f(n) - 2

f(1+1) = f(1) - 2 ... replace every n with 1

f(2) = f(1) - 2

f(2) = 18-2 .... replace f(1) with 18

f(2) = 16

We'll use this to get the next term. Plug in n = 2

f(n+1) = f(n) - 2

f(2+1) = f(2) - 2 ... replace every n with 2

f(3) = f(2) - 2

f(3) = 16 - 2 ... replace f(2) with 16

f(3) = 14

This process keeps going until we reach f(5)

Plug in n = 3

f(n+1) = f(n) - 2

f(3+1) = f(3) - 2

f(4) = f(3) - 2

f(4) = 14-2

f(4) = 12

and finally plug in n = 4

f(n+1) = f(n) - 2

f(4+1) = f(4) - 2

f(5) = f(4) - 2

f(5) = 12 - 2

f(5) = 10

The summary is basically we subtract 2 from each term to get the next term. The sequence is 18, 16, 14, 12, 10 which is arithmetic.

y[tex]\geq[/tex] ..... means full  line and shading above the line

Y< ......means  doted  line and shading below the line

A) solution is overlapping shaded part

B) (10,5)

plug in point in inequalities and check if it's true; if it's true you showed that solution is correct

1. 5[tex]\geq[/tex]-1/2*10 + 2 1/2

  5[tex]\geq[/tex] -5 + 2 1/2

  5[tex]\geq[/tex] -2 1/2 TRUE

2. 5[tex]<[/tex]1/5*10 + 6

   5< 2 + 6

5< 8  TRUE

The solution to the inequality equation is ( -5 , 5 )

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the first inequality relation be represented as A

Now , the value of A is

y ≥ ( -1/2 )x + 2 1/2

y ≥ ( -1/2 )x + 5/2   be equation (1)

Let the second inequality relation be represented as B

Now , the value of B is

y < ( 1/5 )x + 6

On simplifying the equation , we get

Graphing the inequalities we get the common point as ( -5 , 5 )

Substitute the value of x = -5 and y = 5 in the inequality equations , we get

y ≥ ( -1/2 )x + 5/2

Substitute x = -5 and y = 5

5 ≥ ( -1/2 ) ( -5 ) + 5/2

5 ≥ 5/2 + 5/2

5 ≥ 10/2

5 ≥ 5

The inequality is true

Now , y < ( 1/5 )x + 6

Substitute x = -5 and y = 5

5 < ( 1/5 ) ( -5 ) + 6

5 < -1 + 6

5 < 5

The inequality is true when the value of x > -5

Hence , the equations are solved

Answer:

A=40'

Step-by-step explanation:

To me, it seems that the figure is a parallelogram.

So, let's use the formula to calculate the area of a parallelogram.

In this case, the base (b) is 8' and the height (h) is 5'.

Replace the variables with our new values.

A=bh

A=8*5

Calculate the sum.

8*5=40

Add units.

40' or 40 inches.

Hence, 40 inches (40') is our answer.

Answer:

42

Step-by-step explanation:

The chart shows how many bags have a certain number of sweets (e.g. 3 of the 9 bags have 39 sweets). To calculate how many sweets there are in the 10th bag, set up an equation where [tex]x[/tex] represents the number of sweets in the 10th bag:

[tex]\frac{39(3)+40(2)+41(1)+42(1)+43(0)+44(2)+x}{10}=41[/tex]

41 is the mean, which you get by adding the number of sweets in each bag together and dividing it by the number of bags.

Simplify the equation:

[tex]\frac{117+80+41+42+88+x}{10}=41[/tex]

[tex]\frac{368+x}{10} =41[/tex]

Multiply both sides by 10:

[tex]368+x=410[/tex]

Isolate the variable:

Answer:

B. 3 radians

Step-by-step explanation:

We are given the following components of the circle.

Radius of circle (r) = 4 cm

Length of arc (l) = 12 cm

Lenght of arc of a circle is given by the following formula:

[tex] l = \frac{\theta}{2\pi^c}\times 2\pi r[/tex]

Substituting the values of l and r in the above formula, we find:

Answer:

Width of Belmont Avenue is 5.2 meters

Step-by-step explanation:

We use the Pythagoras theorem to solve the problem

Pythagoras Theorem states that:

Hypotenuse² = Base² + Perpendicular²

Danville Street, Belmont Avenue and their diagonal forms a right angled triangle

In this case, let the base be Danville Street with width of 8.1 meters

Let the hypotenuse be 9.6 meters

We need to find the perpendicular

Put the values in Pythagoras theorem.

9.6² = 8.1² + perpendicular²

perpendicular² = 9.6²-8.1²

perpendicular² = 92.16 - 65.61

perpendicular² = 26.55

take square root on both sides

perpendicular =5.153

Round of to nearest 10th

Perpendicular = 5.2 meters

Belmont Avenue = 5.2 meters

Answer:

112 sheep

Step-by-step explanation:

~ If the ratio of sheep:horse is 8:3, and there are 42 horses on the farm, then that means that there are 14 times more horse than 3. Which just means that  ~ 3·14 = 42

~ So we just have to take 8 (The number of sheep), and multiply it by 14, like we did to the number of horse.

~ 8 · 14 = 112

~ Now the new ratio of sheep:horse is 112:42

Answer:

Just like combining like terms with the same variables, you combine like

radicals with the same number under the radical signs.

Step-by-step explanation:

Example:

3x + 2x

= 5x   {combined like terms}

3√2 + 2√2

= 5√2   {combined like radicals}

Combining two or more terms are similar to combining two or more radicals.

What is a radical?

The 'n' th root of a number 'x' is written as [tex]\sqrt[n]{x}[/tex]. It is called a radical.

Combining two or more terms:

(a + 2a + 97a) = 100a

Combining two or more radicals:

(a[tex]\sqrt{3}[/tex] + 9a[tex]\sqrt{3}[/tex] + 90a[tex]\sqrt{3}[/tex]) = 100a[tex]\sqrt{3}[/tex]

Therefore, combining two or more terms are similar to combining two or more radicals.

Answer:

y=(1/9)x+4

Step-by-step explanation:

b=(1/3)x

y=2/6(1/3)x+4

y=(2/18)x+4

y=(1/9)x+4

Answer:

y = 1/(x+2)

Step-by-step explanation:

x=3b and y= 2/(6b+4)

Rewriting the second equation by factoring out 2

y=2/ 2(3b+2)

We know that 3b = x

y=2/ 2(x+2)

Canceling the 2 in the numerator and denominator

y = 1/(x+2)

Compare the x & y values

 [tex]\frac{x_{1}-6}{2}=-5[/tex]             ;      [tex]\frac{y_{1}-3}{2}=-5[/tex]

x₁ - 6 = -5 *2           ;   y₁ - 3 = -5*2

Answer:

1)  =  H

2)  =  0,4

4)  =  S

Step-by-step explanation:

1)  H is found by counting across the horizontal (axis) as x and then downwards the vertical axis for y  as y is a negative we find H for y at ( y = -5 )

But when we always read left to right we start with x first at 3 across. (x= 3) as this is the same as (3,-5)

2)  We find x, y at  (0,4) as 0 is middle of the two axis as they cross each other and 4 goes upwards. x= 0 y =4 = (0,4)

4) S is found as it is a refection of (8,-4) across the y axis.

(x = -8) is still x but it is valued as negative in y  as (x = -8)

Then (y = -4) so it stays the same height as y and represents vertical axis line which is called y axis.

And so y reflects the same height.

But in all the others y represents vertical measure generally.

Whilst x represents horizontal measure generally. they both meet at a point which represents two values generally, like cost and time, network output and population, or cupcakes sales and duration/time.

Answer: H

Answer:

The height of the ramp is 1.39 m.

Step-by-step explanation:

We have,

A wheelchair ramp is 8.0 m long

The angle of inclination is 10°

It is required to find the rise of  the ramp.

Here, hypotenuse is 8 m and angle of inclination is 10°.

Using trigonometry to find it.

[tex]\sin\theta=\dfrac{x}{8}[/tex]

x is rise of the ramp

[tex]x=\sin(8)\times 10\\\\x=1.39\ m[/tex]

So, the height of the ramp is 1.39 m.
