Answer:

Option C

Step-by-step explanation:

Since, measure of all sides of the triangle has been given in the picture,

By applying cosine rule in the given triangle,

AC² = AB² + BC² - 2(AB)(BC)cos(B)

11² = 16² + 16² - 2(16)(16)cos(B)

121 = 256 + 256 - 512.cos(B)

121 - 512 = - 512.cos(B)

cos(B) = [tex]\frac{391}{512}[/tex] = 0.763672

B = [tex]cos^{-1}(0.763672)[/tex]

B = 40.2°

Therefore, measure of angle B is 40.2°.

Option C is the answer.

The three consecutive terms
of an exponential sequence are
the second third and sixth terms
of a linear sequence. Find the
common ratio
the exponential
sequence.​

Answers

Answer:

1

Step-by-step explanation:

The nth term of an exponential sequence is expressed as ar^n-1

The nth term of a linear sequence is expressed as Tn = a + (n-1)d

a is the first term

r is the common ratio

d is the common difference

n is the number of terms

Let the three consecutive terms  of an exponential sequence be a/r, a and ar

second term of a linear sequence = a +d

third term of a linear sequence = a + 2d

sixth term of a linear sequence = a + 5d

Now if the three consecutive terms  of an exponential sequence are  the second third and sixth terms  of a linear sequence, this is expressed as;

a/r = a + d ..... 1

a = a + 2d ..... 2

ar = a+ 5d .... 3

From 2: a = a + 2d

a-a= 2d

0 = 2d

d = 0/2

d = 0

Substitute d = 0 into equation 1:

From 1: a/r = a + d

a/r = a+0

a/r = a

Cross multiply

a = ar

a/a = r

1 = r

Rearrange

r = 1

Hence the common ratio of the exponential sequence is 1

Step-by-step explanation:

The student council at Summerfield High School is making T-shirts to sell for a fundraiser, at a price of $11 apiece. The costs, meanwhile, are $10 per shirt, plus a setup fee of $141. Selling a certain number of shirts will allow the student council to cover their costs. What will the costs be? How many shirts must be sold?

Answers

Answer:

$1551 needed to cover the costs and 141 shirts will be sold.

Step-by-step explanation:

If a shirt costs $10 and the council is selling the shirt for $1 more ($11), after selling 141 shirts, they would have made a profit of $1*141=$141. Since there is also a setup fee of $141, the profit would actually be $0. This is when the costs are covered.

C = 10s + 141 (C is cost and s in no. of shirts sold)

s = 141

C = 141*10 + 141 = 1551

Answers

Answer:

a) tan x = 1

b) tany = 4 + tanx /2tanx - 3

Step-by-step explanation:

a) Given the equation

2(sinx + 2cosx) = sinx +5cosx

Open the bracket

2sinx + 4cosx =  sinx +5cosx

Collect like terms

2sinx - sinx = 5cosx - 4cosx

sinx = cos x

Divide both sides by cos x

sinx/cosx = cosx/cosx

tanx = 1

Hence the value of tan x is 1

b) Given the expression

sinxcosy + 3cosxsiny = 2sinxsiny - 4cosxcosy

We are to express tany in terms of tan x

Divide through by cosx cosy

sinxcosy/cosx cosy + 3cosxsiny/cosx cosy = 2sinxsiny/cosx cosy - 4cosxcosy/cosx cosy

sinx/cosx + 3siny/cosy = 2tanxtany - 4

tanx +3tany =  2tanxtany - 4

Collect like terms

tanx - 2tanxtany = -4 - 3tany

- 2tanxtany+3tany = -4 - tanx

tany (-2tanx+3) = -4 - tanx

tan y = -4 - tanx/-2tanx+3

tan y = -(4+tanx)/-(2tanx-3)

tany = 4 + tanx /2tanx - 3

Hence the function of tany in term of tan x is tany = 4 + tanx /2tanx - 3

Rodger put $1,000 in a bank account that pays 5% annual simple interest. At the end of four years, how much interest has he earned and what is the balance of his account

Answers

Answer: He has earned $200 interest and the balance of his account is $1,200.

Step-by-step explanation:

Given: Principal : P = $1,000

Simple interest rate : r = 5% = 0.05

Time: t = 4 years

Simple interest = [tex]Prt[/tex]

[tex]=1000\times0.05\times4=200[/tex]

i.e. Simple interest = $200

Balance of account = Principal + Simple interest

=  $1,000 + $200

= $1,200

Hence, he has earned $200 interest and the balance of his account is $1,200.

In a right triangle the length of a hypotinuse is c and the length of the other leg is a. Find the length of the other leg b, if: c=5, a=3

Answers

Answer:

b = 4

Step-by-step explanation:

a^2 + b^2 = c^2

a = 3

b = b

c = 5

a^2 + b^2 = c^2

(3)^2 + b^2 = (5)^2

9 + b^2 = 25

b^2 = 25 - 9

b^2 = 16

√b^2 = √16

b = 4

The local Farm Market sells peppers at five for $2.25. Complete the rate table.

Answers

number of peppers (in $)
1 pepper - 0.45
2 peppers - 0.90
3 peppers - 1.35
4 peppers - 1.80
5 peppers - 2.25
10 peppers - 4.50
15 peppers - 6.75
20 peppers - 9
100 peppers - 45

for 20$ you could buy 44 peppers (20 divided by 0.45)


The proportionality is 0.45, then the equation is C = 0.45 n. The number of peppers you buy for $20 will be 44.44. Then the table is completed below.

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Let 'C' be the cost and 'n' be the number of peppers. Then the proportionality is given as,

C ∝ kn

At n = 5, the cost C = 2.25, then we have

2.25 = k (5)

k = 2.25 / 5

k = 0.45

Then the equation is given as,

C = 0.45 n

The number of peppers you buy for $20 will be given as,

20 = 0.45 n

n = 44.44

Then the table is completed below.

Number of peppers             Cost

              1                              $0.45

             2                              $0.90

             3                              $1.35

             4                              $1.80

             5                              $2.25

            10                              $4.50

            15                              $6.75

           20                              $9

          100                              $45
