The missing terms of the arithmetic sequence -13, - 6,  1 , 8 , 15,  22.

an = a1, a2, a3, a4, a5, a6

formula for nth term is :

an = a + (n - 1)d

where

an = last term

a = a1 = first term

n = number of terms

d = difference between two terms

here

a2 = a + d

- 6 = a + d    ....(1)

a5 = a + 4d

15 = a + 4d      .......(2)

on solving equation we get :

- 6 = a   +    d    ....(1)

15 =  a    +    4d      .......(2)

(-)    (-)      (-)

- 21 =  - 3d

d = 21/3

d = 7

using the value of d in equation the value of a is :

- 6 = a + d  

-6  = a + 7

a = -6 -7 = -13

then

a1 = a = -13

a2 = a + d  = -13 + 7 = -6

a3 = a + 2d  = -13 +2 x 7 = 1

a4 = a + 3d =  -13 + 3 x 7 = 8

a5 = a + 4d =  -13 +4 x 7 = 15

a6 = a + 5d = -13 +5 x 7 = 22

Using metric units, the cost of rice in London is ₤0.85 per pound

To solve this problem, we need to convert the price per kilogram to price per pound.

We can use the conversion factor of

1 pound = 0.454kg

And

$1 = ₤1.18

Let's proceed to convert from kilogram to pounds since the currency is already in the desired unit.

1lb = 0.454kg

x = 1kg

x = 1 / 0.454

x = 2.2lb

This implies that

₤1.88 = 2.2lb

x = 1lb

x = (1.88 * 1) / 2.2

x = 0.85

This becomes ₤0.85 per pound

The given function is linear and constant because your equation is represented by the standard form for the linear equation.

A linear function can be represented by an equation. The standard form for the linear equation is: y= mx+b , for example, y=6x+4. Where:

m= the slope.

b= the constant term that represents the y-intercept

For the given example: m=6 and b=4.

An equation is classified as nonlinear when it is not represented by the standard form for the linear equation. For example, 2x²+x+10, x², x³, x³ +2, etc.

The given equation is  4y=24. Firstly, you should rewrite it  to the standard form for the linear equation is: y= mx+b. Therefore,

4y=24

y=24/4

y=6

If the standard form for the linear equation is y= mx+b, for the given equation m=0 and b=6. Thus, the given equations is linear and constant. It can be classified for constant because for any value of x, the value of y always be equal to 6.

The independent variable in this situation is C. area of the prism.

In mathematical modeling, statistical modeling, and experimental sciences, dependent and independent variables are variables. Dependent variables are so named because their values are studied in an experiment under the assumption or demand that they are dependent, by some law or rule, on the values of other variables.

The term "independent variable" means exactly what it sounds like. It is a variable that is independent of the other variables you are attempting to measure. For example, age could be an independent variable.

Answer:

y=-3/2x +2

Step-by-step explanation:

Answer:

y = 1.50x +2

Step-by-step explanation:

First, we must find two points.

Equation of a straight line:

y = mx + b ------(i)

Step 1: Calculating Slope (m).

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{2-0.500}{1-0}[/tex]

[tex]m=\frac{1.50}{1}[/tex]

[tex]m=1.50[/tex]

Now putting value of m in equation (i)

                             y = 1.50x + b -----(ii)

Step 2: Calculating Y-intercept (b).

Lets choose the first point, (0,2) for calculating y-intercept:

2 = 1.50(0) + b

2 = 0 + b

2 = b

b = 2

Now putting value of b in equation (ii)

y = 1.50x + 2

The trigonometric expression tan² x + 1 = sec² x is proved by using the fundamental trigonometric formula and the definition of tangent and secant.

In this problem we must prove the existence of a trigonometric formula by means of definitions of trigonometric functions and the fundamental trigonometric formula.

Step 1 - Introduce the fundamental trigonometric formula and the definitions of tangent and secant:

sin² x + cos² x = 1, tan x = sin x / cos x, sec x = 1 / cos x

Step 2 - Divide each side of the formula by cos² x:

sin² x / cos² x + cos² x / cos² x = 1 / cos² x

(sin x / cos x)² + 1 = (1 / cos x)²

Step 3 - Use the definition of the two trigonometric functions:

tan² x + 1 = sec² x

what is true statement?

A statement is true if the assertion it makes is true, and it is false if the assertion it makes is untrue. For example, the statement "The trains are always late" is only accurate if the situation it describes—that is, if the trains are indeed always late—actually exists.

As given, Damon is saving for a vacation.

He estimates that he’ll need about $2,500 for the trip.

He created an equation last week to model his savings plan to determine how many more months of saving it will take to reach his goal.

In the equation Damon created, x represents the number of months since last week and y represents the total amount he’s saved for the vacation.

The statements are,

Step 1: y = 500 + 400x

Step 2: y - 500 = 500 + 400x - 500

Step 3: y - 500 = 400x

Step 4: y - 500/400 = 400x/400

Step 5: y - 500/400 = x

Step 6: 2500 - 500/400 = x

We have proved the given trigonometric equations by using trigonometric identities.

What are the trigonometric identities?

Pythagorean identities, reciprocal identities, sum and difference identities, and double-angle and half-angle identities are the most important trigonometric identities. We'll need to apply the sine and cosine rules to non-right-angled triangles.

For the first equation:

The given equation is

              [tex]sec(x)[sec(x)-cos(x)]+\frac{sin(x) + cos(x)}{sin(x)}-cotx=sec^2(x)[/tex]

Now simplifying the given equation, we can write

[tex]LHA= sec(x)[sec(x)-cos(x)]+\frac{sin(x) + cos(x)}{sin(x)}-cotx\\\\LHS=sec^2(x)-sec(x)cos(x)+\frac{sin(x)}{sin(x)}+\frac{cos(x)}{sin(x)}-cot(x)\\\\LHS=sec^2(x)-1+1+cot(x)-cot(x)\\\\LHS=sec^2(x)[/tex]

LHS = RHS.

Hence proved.

For the second equation:

     cos(π - Θ) + sin(π/2 + Θ) = 0

LHS = cos(π - Θ) + sin(π/2 + Θ)

      = -cosΘ + cosΘ

      = 0

LHS = RHS

The gas bill exceeded $87 from last month to this month.

We know simple interest (SI) is given by SI = (p×r×t)/100, where

p = principle, r = rate in percentage, and t = time in years.

Given, The Haddad expected the automatic withdrawal of their gas bill to

be more than last month's bill of $215.85 but did not know by how much.

Their account showed a previous balance of $417.80, $350.00 in deposited checks, and an automatic deposit of $150.00.

∴ Their current balance is (417.80 + 250 + 150) = $817.8 and $5.25 in interest which is (105/100)×$817.7 = $858.69.

Haddads' present balance is $555.82,
