Answer:

The correct answer is last option

(y - 4) = 3/4(x - 2)

Step-by-step explanation:

It is given a graph with a line

<u>To find the slope of line</u>

The two points on the line are (2, 4) and (-6, -2)

Slope = (y₂ - y₁)/(x₂ - x₁)

  = (-2 - 4)/(-6 - 2)

  = -6/-8

  = 3/4

<u>To find the equation</u>

(x₁, y₁) = (2, 4)

(y - y₁)/(x - x₁) = 3/4

(y - 4)/(x - 2) = 3/4

(y - 4) = 3/4(x - 2)

Therefore the correct answer is last option

Angelina wins money in a competition. She is given the choice as to how she is paid.
NISA [10]

Answer:

  • Choice 1
  • 20 days

Step-by-step explanation:

You are being asked to compare the value of a growing infinite geometric series to a fixed constant. Such a series will always eventually have a sum that exceeds any given fixed constant.

__

<h3>a)</h3>

Angelina will get more money from the Choice 1 method of payment. The sequence of payments is a (growing) geometric sequence, so the payments and their sum will eventually exceed the alternative.

__

<h3>c)</h3>

For a first term of 1 and a common ratio of 2, the sum of n terms of the geometric series is given by ...

  Sn = a1×(r^n -1)/(r -1) . . . . . . . . . . series with first term a1, common ratio r

We want to find n such that ...

  Sn ≥ 1,000,000

  1 × (2^n -1)/(2 -1) ≥ 1,000,000

  2^n ≥ 1,000,001 . . . . add 1

  n ≥ log(1,000,001)/log(2) . . . . . take the base-2 logarithm

  n ≥ 19.93

The total Angelina receives from Choice 1 will exceed $1,000,000 after 20 days.

m∠FDE = 52°

Solution:

Given data:

DE ≅ DF, CD || BE, BC || FD and m∠ABF = 116°

<em>Sum of the adjacent angles in a straight line = 180°</em>

m∠ABF + m∠CBF = 180°

116° + m∠CBF = 180°

m∠CBF = 64°

If CD || BE, then CD || BF.

Hence CD || BE and BE || FD.

Therefore BFCD is a parallelogam.

<em>In parallelogram, Adjacent angles form a linear pair.</em>

m∠CBF + m∠BFD = 180°

64° + m∠BFD = 180°

m∠BFD = 116°

<em>Sum of the adjacent angles in a straight line = 180°</em>

m∠BFD + m∠DFE = 180°

116° + m∠DFE = 180°

m∠DFE = 64°

we know that DE ≅ DF.

<em>In triangle, angles opposite to equal sides are equal.</em>

m∠DFE = m∠DEF

m∠DEF = 64°

<em>sum of all the angles of a triangle = 180°</em>

m∠DFE + m∠DEF + m∠FDE = 180°

64° + 64° + m∠FDE = 180°

m∠FDE = 52°

Find the area of a rectangle with a perimeter of 12 meters and a base of 4 meters
stepladder [879]
Considering the perimeter (P)
p = 2 \times b + 2 \times h
where b is the base and h is the height, then
12 = 2 \times 4 \times 2 \times h \\  \\ h =  \frac{12 - (2 \times 4)}{2}  \\  \\ h = 2
Being the area (A)
a = b \times h \\  \\ a = 4 \times 2 \\  \\ a = 8 {m}^{2}
