Answer:

ur question is not complete.

Answer:

5th term: -10

Step-by-step explanation:

To find the nth term in the sequence, you can substitute n into the equation:

d(n) = 6 - 4(n - 1)

Since we want the 5th term, we substitute 5:

d(5) = 6 - 4(5 - 1)

d(5) = 6 - 4(4)

d(5) = 6 - 16

d(5) = -10

Answer: 37m

Step-by-step explanation:

Convert 300cm into m = 3m

6 + 6 + 3 + 3 + 3.5 + 3.5 + 12 = 37m

Step-by-step explanation:

1 pound= 16 ounces

So half pound= ½×16= 8 ounces

Answer:

See attachment for graph

Step-by-step explanation:

Given

[tex]y = x^2 - 3[/tex]

Required

The graph of the equation

First, we determine the range of y

[tex]x = -3[/tex]

[tex]y = x^2 - 3 \to y = (-3)^2 - 3 = 6[/tex]

[tex](-3,6)[/tex]

[tex]x = -2[/tex]

[tex]y = (-2)^2 - 3 = 1[/tex]

[tex](-2,1)[/tex]

[tex]x = -1[/tex]

[tex]y = (-1)^2 - 3 = -2[/tex]

[tex](-1,-2)[/tex]

[tex]x=0[/tex]

[tex]y = 0^2 - 3 = -3[/tex]

[tex](0,-3)[/tex]

[tex]x = 1[/tex]

[tex]y= 1^2 - 3 = -2[/tex]

[tex](1,-2)[/tex]

[tex]x = 2[/tex]

[tex]y =2^2 - 3 = 1[/tex]

[tex](2,1)[/tex]

[tex]x = 3[/tex]

[tex]y = 3^2 - 3 = 6[/tex]

[tex](3,6)[/tex]

See attachment for graph

Answer:

[tex]x=6[/tex]

Step-by-step explanation:

The lengths of line segments [tex]\overline{AB}[/tex] and [tex]\overline{AC}[/tex] because of the two segments and two angles marked as equal in the diagram. Because of this, the arcs [tex]\widehat{AB}[/tex] and [tex]\widehat{AC}[/tex] are equal.

Since there are 360 degrees in a circle, we can now set up the following equation:

[tex](10x-23)+(10x-23)+106=180,\\20x-46+106=180,\\20x+60=180,\\20x=120,\\x=\boxed{6}[/tex]

Answer:

Consistent and dependent

Step-by-step explanation:

Given

[tex]3y = 9x - 6[/tex]

[tex]2y + 6x = 4[/tex]

Required

The words that describe the equations

Make y the subject in (2)

[tex]2y + 6x = 4[/tex]

Collect like terms

[tex]2y = 4 - 6x[/tex]

Divide through by 2

[tex]y = 2 - 3x[/tex]

Substitute: [tex]y = 2 - 3x[/tex] in (1)

[tex]3y = 9x - 6[/tex]

[tex]3(2 - 3x) = 9x - 6[/tex]

[tex]6 - 9x = 9x - 6[/tex]

Collect like terms

[tex]9x+9x = 6+6[/tex]

[tex]18x = 12[/tex]

Solve for x

[tex]x = \frac{12}{18}[/tex]

Simplify

[tex]x = \frac{2}{3}[/tex]

Substitute [tex]x = \frac{2}{3}[/tex] in [tex]y = 2 - 3x[/tex]

[tex]y = 2 - 3*\frac{2}{3}[/tex]

[tex]y = 2 - 2[/tex]

[tex]y =0[/tex]

So, we have:

[tex]x = \frac{2}{3}[/tex] and [tex]y =0[/tex]

The system is consistent because it has at least 1 solution

The system is dependent because it has more than 1 solution

Answer:

[tex]Mode = 30[/tex]

Step-by-step explanation:

Given

[tex]\mu = 30[/tex] --- Mean

Required

The possible value of the mode

For a bell-shaped distribution, we have:

[tex]Mean = Mode[/tex]

Rewrite as:

[tex]Mode = Mean[/tex]

This gives;

[tex]Mode = \mu[/tex]

Hence:

[tex]Mode = 30[/tex]

Answer:

For a bell-shaped distribution with µ = 30,

Mode =30

Answer:

  392 ft

Step-by-step explanation:

As in the attached figure, you seem to have sides b and c of the triangle, along with angle C. You want to find side 'a'. The law of sines can be used to find angle B, then angle A can be found from the sum of angles. Knowing angle A, we can find side 'a'.

  sin(B)/b = sin(C)/c

  sin(B) = (b/c)sin(C) = 400/550·sin(88°)

  B = arcsin(8/11·sin(88°)) ≈ 46.621°

Then angle A = ...

  A = 180° - B - C = 180° -46.621° -88° = 45.379°

Now, we can find side 'a' from ...

  a/sin(A) = c/sin(C)

  a = c·sin(A)/sin(C) ≈ 550·sin(45.379°)/sin(88°) ≈ 391.710 . . . feet

The unknown side of the triangle is about 392 feet.

3. 8+5

4. 2x - 8

Step-by-step explanation:

3. for example : 5 more than the number means

x+5 so that's how we get the answer as 8+5

4. This can be explained in two folds firstly, for example: 2 less than the number means x-2.

secondly;7 times the number means 7x so therefore we get our final answer as 2x - 8

Answer:

[tex]first \ week \ = 15.10 * 38 = 573.80\\Second\ week \ = 15.10 *38 = 573.80\\\\Total \ amount \ before \ all \ deductions = 1147.60\\[/tex]

FICA deduction 7.65%

                       = [tex]\frac{7.65}{100} * 1147.60 = 87.79[/tex]

Federal withholding 8%

                       =[tex]\frac{8}{100} * 1147.60= 91.81[/tex]

State withholding 3%

                         =[tex]\frac{3}{100} *1147.60 = 34.43[/tex]

Amount on paycheck = 1147.60 - 87.79 - 91.81 - 34.43 = $933.57

Answer: q=6

Step-by-step explanation:

Answer:

The value of [tex]q[/tex] is [tex]\mathbf{6}[/tex]

Step-by-step explanation:

The sum of the angles [tex](9q-8)^\circ[/tex] and [tex]134^\circ[/tex] should be equal to [tex]180^\circ[/tex]

  [tex](9q-8)+134^\circ=180^\circ[/tex]

therefore

  [tex]9q-8^\circ+134^\circ=180^\circ\\9q=180^\circ-134^\circ+8^\circ\\9q=54^\circ\\q=\frac{54^\circ}{9} \;\;\;\;\;\;\;\;\;\;\Rightarrow\;\;\;\;\;\;\;\;\;\;\mathbf{q=6^\circ}[/tex]

Answer:

(16, 24, 7)

Step-by-step explanation:

The Triangle Inequality states that the sum of lengths of any two sides should be greater than the length of the third side.

But 16 + 7 = 23 is not greater than 24.

Answer:

Step-by-step explanation:

Discussing interest starts with the principal, or amount your account starts with. This could be a starting investment, or the starting amount of a loan. Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5. The total amount you would repay would be $105, the original principal plus the interest.

Answer:

$15.75 change

Step-by-step explanation:

Avery starts with $20.

She buys 2 tacos and 1 soda.

$1.25 + $1.25 + $1.75

= $4.25

$20 that she started with - $4.25 that she used.

$20 - $4.25 = $15.75

Answer:

15.75

Step-by-step explanation:

$20 - ($1.25 x 2) - $1.75 =

20 - 2.5 - 1.75 =

17.5 - 1.75 =

$15.75
