Answer: C

Step-by-step explanation:

At a = 2 and b = -3, the correct expression which has the largest value is,

⇒ 2a - 3b

What is an expression?

Given that;

The expressions are,

A. 2a+3b

B. 3a+2b

C. 2a-3b

D. 3a-2b

Put a = 2 and b = - 3 in expressions as;

A. 2a + 3b

⇒ 2 × 2 + 3 × - 3

⇒ 4 - 9

⇒ - 5

B. 3a+2b

⇒ 3 × 2 + 2 × - 3

⇒ 6 - 6

⇒ 0

C. 2a-3b

⇒ 2 × 2 - 3 × - 3

⇒ 4 + 9

Find the volume of the regular hexagonal pyramid if the lateral edge is 15 feet.

Answers

Answer:

Volume of the given pyramid = 1122.37 cubic feet

Step-by-step explanation:

Volume of the regular hexagonal pyramid = [tex]\frac{1}{3}(\text{Area of the base})(\text{Base})[/tex]

Measure of internal angle of a polygon = [tex]\frac{(n-2)\times 180}{n}[/tex]

Here, n = number of sides of the polygon

For a hexagon, n = 6

Measure of interior ∠C = [tex]\frac{(6-2)\times 180}{6}[/tex]

                                       = 120°

Measure of ∠BCD = [tex]\frac{120}{2}[/tex]

                              = 60°

By applying tangent rule in ΔCED,

tan(∠ECD) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(60°) = [tex]\frac{DE}{CE}[/tex]

[tex]\sqrt{3}=\frac{DE}{6}[/tex]

DE = [tex]6\sqrt{3}[/tex] feet

And cos(60°) = [tex]\frac{EC}{CD}[/tex]

[tex]\frac{1}{2}=\frac{6}{CD}[/tex]

CD = 12 feet

Area of ΔBCD = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                        =  [tex]\frac{1}{2}(6\sqrt{3})(12)[/tex]

                        = [tex]36\sqrt{3}[/tex] feet

Area of hexagonal Base of the pyramid = [tex]6(36\sqrt{3})[/tex]

                                                                  = 216√3 square feet

Since, lateral height of the pyramid (AC) = 15 feet

By applying Pythagoras theorem in ΔADC,

AC² = AD² + CD²

(15)² = AD² + (12)²

AD = [tex]\sqrt{225-144}[/tex]

AD = 9 feet

Volume of the given pyramid = [tex]\frac{1}{3}(216\sqrt{3})(9)[/tex]

                                                 = 648√3 cubic feet

                                                 = 1122.37 cubic feet

We are painting a rectangular wall of a large room. The dimensions of the wall are 35feet long and 21.5 feet wide. If the total cost of the paint was 421.40 what was the cost in dollars of the paint rounded to the nearest cent

Answers

Answer:

56 cent per ft²

Step-by-step explanation:

Wall dimension = 35 feets * 21.5 feets

Total cost of paint used = 421.40

Area of wall = Area of rectangle = Length * width

Area of wall = 35 feets * 21.5 feets

Area of wall = 752.5 ft²

Cost of paint per square feet:

Total coast of paint / Area of wall

$421.40 / 752.5 ft²

= $0.56 per ft²

= 0.56 * 100 = 56

0.4x - 1.2 = 0.15x + 0.8 ?????????

Answers

Answer:

x = 8

Step-by-step explanation:

0.4x - 1.2 = 0.15x + 0.8

0.4x - 1.2 + 1.2 = 0.4x

0.15x + 0.8 + 1.2 = 0.15x + 2

0.4x = 0.15x + 2

0.4x - 0.15x = 0.25x

0.15x + 2 - 0.15x = 2

0.25x = 2

0.25x / 0.25 = x

2 / 0.25 = 8

x = 8

Use sigma notation to represent the sum of a geometric series with a first term of 3 and a common ratio of . A. B. C. D.

Answers

Answer:

[tex]\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}][/tex]

Step-by-step explanation:

A geometric sequence is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.

The first term is denoted by a and the common ratio is denoted by r.

A geometric sequence has the form:

a, ar, ar², ar³, . . .

The nth term of a geometric sequence is [tex]ar^{n-1}[/tex]

Therefore the sum of the first n terms is:

[tex]\Sigma_{k=1}^{n}(ar^{k-1})[/tex]

Given a geometric series with a first term of 3 and a common ratio of 10/9, the sum of the first n terms is:

[tex]\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}][/tex]
