Answer:

Use the coordinate plane below to answer the following questions. a. Use a straightedge to construct a line that goes.

Step-by-step explanation:

The 1/4x is the slope and +2 is (2,0).

Answer:

c = -1/4

e = 1 2/5

Step-by-step explanation:

4c - 5 = -6

add 5 to both sides

4c = -1

divide each side by 4

c = -1/4

5e + 2 = 9

subtract 2 from both sides

5e = 7

divide both sides by 5

e = 1 2/5

Answer:

c = -1/4

e = 7/5

Step-by-step explanation:

1. 4c - 5 = -6, 4c = -1, c = -1/4

2. 5e + 2 = 9, 5e = 7, e = 7/5

Answer:

Answer :- Statement (B) ,C'D' ll AB

Given AB is parallel to CD.  CD rotated.

Consider a transversal line l intersecting AB and CD at angle x.

therefore By slope formula,

slope of AB and CD = m =tanx

Now after rotation of 180 CD become C'D'

therefore, slope of C'D' = =tanx=m

Hence C'D' ll AB.

Answer: 2400

Step-by-step explanation:

120*20

The  power consumed by circuit is 2400 watt

The quantity of energy transferred or transformed per unit of time is known as power. The watt, or one joule per second, is the unit of power in the International System of Units.

Electrical power is the product of voltage and current. P = V X I .

Given:

Potential Difference= 120 vatt

Current = 20 Ampere

Now, using

Power = V x I

Power= 120 x 20

Power = 2400 Watt

Hence, the power consumed by circuit is 2400 watt

Answer:

£9184

Step-by-step explanation:

Interest = PRT/100

P = Price

R = Rate

T = time

First Let's find the interest for 2 years

[tex]interest = \frac{8200 \times 6 \times 2}{100} \\ = 984[/tex]

So, the interest is £984

Now let's find the full amount he received after two years ,

[tex]8200 + 984 = 9184[/tex]

Geometric sequence is characterized by a common ratio

(1) Sum of first 5 terms

The first term of the sequence is:

[tex]\mathbf{a = 3}[/tex]

The common ratio (r) is:

[tex]\mathbf{r = 6 \div 3 = 2}[/tex]

The sum of n terms is calculated using:

[tex]\mathbf{S_n = \frac{a(r^n - 1)}{r - 1}}[/tex]

So, we have:

[tex]\mathbf{S_5 = \frac{3 \times (2^5 - 1)}{2 - 1}}[/tex]

[tex]\mathbf{S_5 = \frac{93}{1}}[/tex]

[tex]\mathbf{S_5 = 93}[/tex]

Hence, the sum of the first five terms is 93

(2) Sum of first 5 terms

The first term of the sequence is:

[tex]\mathbf{a = 14}[/tex]

The common ratio (r) is:

[tex]\mathbf{r = 3}[/tex]

The sum of n terms is calculated using:

[tex]\mathbf{S_n = \frac{a(r^n - 1)}{r - 1}}[/tex]

So, we have:

[tex]\mathbf{S_5 = \frac{14 \times (3^5 - 1)}{3 - 1}}[/tex]

[tex]\mathbf{S_5 = \frac{3388}{2}}[/tex]

[tex]\mathbf{S_5 = 1694}[/tex]

Hence, the sum of the first five terms is 1694

(3) Sum of first n terms

The first term of the sequence is:

[tex]\mathbf{a = 318}[/tex]

The common ratio (r) is:

[tex]\mathbf{r = \frac12}[/tex]

The sum of n terms is calculated using:

[tex]\mathbf{S_n = \frac{a(1 - r^n)}{1 - r}}[/tex]

So, we have:

[tex]\mathbf{S_n = \frac{318 \times (1 - \frac 12^n)}{1 - \frac 12}}[/tex]

[tex]\mathbf{S_n = \frac{318 \times (1 - \frac 12^n)}{\frac 12}}[/tex]

[tex]\mathbf{S_n = 636 (1 - \frac 12^n)}[/tex]

Hence, the sum of the first n terms is [tex]\mathbf{ 636 (1 - \frac 12^n)}[/tex]

(4) The first term

The sum of the first 7th term of the sequence is:

[tex]\mathbf{S_7 = 547}[/tex]

The common ratio (r) is:

[tex]\mathbf{r = -3}[/tex]

The sum of n terms is calculated using:

[tex]\mathbf{S_n = \frac{a(1 - r^n)}{1 - r}}[/tex]

So, we have:

[tex]\mathbf{547 = \frac{a(1 - (-3)^7)}{1 - -3}}[/tex]

[tex]\mathbf{547 = \frac{a(2188)}{4}}[/tex]

Multiply both sides by 4

[tex]\mathbf{2188= a(2188)}[/tex]

Divide both sides by 2188

[tex]\mathbf{1= a}[/tex]

Rewrite as:

[tex]\mathbf{a = 1}[/tex]

Hence, the first term is 1

(5) Find the 7th term

The first term of the sequence is:

[tex]\mathbf{a=2}[/tex]

The common ratio (r) is:

[tex]\mathbf{r=3}[/tex]

The nth term of a geometric sequence is:

[tex]\mathbf{T_n = ar^{n -1}}[/tex]

So, we have:

[tex]\mathbf{T_7 = 2 \times 3^{7 -1}}[/tex]

[tex]\mathbf{T_7 = 1458}[/tex]

Hence, the seventh term is 1458

(6) Sum of geometric sequence

The first term of the sequence is:

[tex]\mathbf{a=2}[/tex]

The common ratio of the sequence is:

[tex]\mathbf{r = 6 \div 2 = 3}[/tex]

The number of terms is:

[tex]\mathbf{n = 5}[/tex]

The sum of n terms is calculated using:

[tex]\mathbf{S_n = \frac{a(r^n - 1)}{r - 1}}[/tex]

So, we have:

[tex]\mathbf{S_5 = \frac{2 \times (3^5 - 1)}{3 - 1}}[/tex]

[tex]\mathbf{S_5 = \frac{484}{2}}[/tex]

[tex]\mathbf{S_5 = 242}[/tex]

Hence, the sum of the first five terms is 242

(7) The first term

The sum of the first five terms is given as:

[tex]\mathbf{S_5 = 341}[/tex]

The common ratio is:

[tex]\mathbf{r = 4}[/tex]

The sum of n terms is calculated using:

[tex]\mathbf{S_n = \frac{a(r^n - 1)}{r - 1}}[/tex]

So, we have:

[tex]\mathbf{341 = \frac{a \times (4^5 - 1)}{4 - 1}}[/tex]

[tex]\mathbf{341 = \frac{a \times 1023}{3}}[/tex]

Solve for a

[tex]\mathbf{a = \frac{3 \times 341}{1023}}[/tex]

[tex]\mathbf{a = 1}[/tex]

Hence, the first terms is 1

(8) Sum to infinite

The first term of the sequence is:

[tex]\mathbf{a = 192}[/tex]

The common ratio (r) is:

[tex]\mathbf{r = \frac 14}[/tex]

The sum to infinite is:

[tex]\mathbf{S_{\infty} = \frac{a}{1 - r}}[/tex]

So, we have:

[tex]\mathbf{S_{\infty} = \frac{192}{1 - 1/4}}[/tex]

[tex]\mathbf{S_{\infty} = \frac{192}{3/4}}[/tex]

[tex]\mathbf{S_{\infty} = 256}[/tex]

Hence, the sum to infinite is 256
