Answer:

128°

Explanation:

total sum of interior angle in triangle is 180°

Find the missing angle inside the triangle:

180° - 38° - 90°

52°

∵ a straight line always has 180°

Now find for missing exterior angle:

x° + 52° = 180°

x° = 180° - 52°

x° = 128°

Answer:

128 degrees

Step-by-step explanation:

180-52= 128

so your answer is 128 degrees.

Answer:

9.2 cm and 15% increase

Step-by-step explanation:

1.15*8 = 9.2

percentage increase

new square = 9.2*9.2 =84.64

old area=8*9.2 = 73.6

percentange increase = (84.64-73.6)/73.6 = 15%

Increase the width

As sides of square are equal

Area increases same as length i.e 15%

Answer:

$15348

Step-by-step explanation:

i = prt is the simple interest equation

i = 12,000(0.031) = 372

i = 372*9 = 3348

12000+3348 = $15348

Answer:

Step-by-step explanation:

I=PRT

I=12,000(3.1%)

I=12,000(0.031)=372

I=372*9=3348

The total interest paid is $3,348.

Answer:

The line passes through the given points are ( 10,8) & (7,14)

here

x₁ = 10

y₁ = 8

x₂ = 7

y₂ = 14

We have been asked to slope of that line which passes through the given points .

Using Formulae

❍[tex] \bf \: m \: = \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Put the given value we obtain

[tex] \sf \dashrightarrow \: m \: = \dfrac{14 - 8}{7 - 10} \\ \\ \sf \dashrightarrow \: m \: = \dfrac{6}{ - 3} \\ \\ \sf \dashrightarrow \: m \: = \dfrac{ - 2}{1} \\ \\ \sf \dashrightarrow \: m \: = - 2[/tex]

So, the slope of that line is -2 .

Answer:irrational, rational, non-reapting and non-terminating and irrational

Step-by-step explanation:

because

Here , we are provided with a table which shows 5 consecutive terms of an arithmetic sequence . But before solving further , let's recall that ;

The n'th term of a Arithmetic Sequence let's say it be [tex]{\sf T_n}[/tex] is given by ;

Where , d is the common difference

Now , here we are given with ;

[tex]{\quad \qquad \sf \blacktriangleright \blacktriangleright \blacktriangleright T_{1}=8 \: and \: T_{5}=-4}[/tex]

We have to find the 2nd , 3rd and 4th term respectively ,

Now , by using the above formula , 5th term can be written as ;

[tex]{: \implies \quad \sf T_{1}+(5-1)d=T_{5}}[/tex]

Putting the values and transposing 1st term to RHS , we have ;

[tex]{: \implies \quad \sf 4d = -4-8}[/tex]

[tex]{: \implies \quad \sf d=-\dfrac{12}{4}}[/tex]

[tex]{: \implies \quad \sf d=-3}[/tex]

Now , as we got the common difference , so we can find out the missing terms now ;

[tex]{: \implies \quad \sf T_{2}= T_{1}+(2-1)d}[/tex]

[tex]{: \implies \quad \sf T_{2}= 8 +d}[/tex]

[tex]{: \implies \quad \sf T_{2}= 8-3}[/tex]

[tex]{: \implies \quad \bf \therefore \: T_{2}= 5}[/tex]

Now

[tex]{: \implies \quad \sf T_{3}= T_{1}+(3-1)d}[/tex]

[tex]{: \implies \quad \sf T_{3}= 8 +2d}[/tex]

[tex]{: \implies \quad \sf T_{3}= 8-6}[/tex]

[tex]{: \implies \quad \bf \therefore \: T_{3}= 2}[/tex]

Also ,

[tex]{: \implies \quad \sf T_{4}= T_{1}+(4-1)d}[/tex]

[tex]{: \implies \quad \sf T_{4}= 8 +3d}[/tex]

[tex]{: \implies \quad \sf T_{4}= 8-9}[/tex]

[tex]{: \implies \quad \bf \therefore \: T_{4}= -1}[/tex]

Now , The given table can be written as ;

[tex]{\begin{array}{|c|c|c|c|c|c|}\cline{1-6} \bf n & \sf 1 & 2 & 3 & 4 & 5 \\ \cline{1-6} \bf T_{n} & \sf 8 & 5 & 2 & -1 & -4 \end{array}}[/tex]

Given the data from the question, the 2nd, 3rd and 4th term of the sequence are:

This is a type of sequence which have common difference between each term. It is represent mathematically as:

Tₙ = a + (n – 1)d

Where

Tₙ is the nth term

a is the first term

n is the number of terms

d is the common difference

Tₙ = a + (n – 1)d

T₅ = 8 + (5 – 1)d

–4 = 8 + (4)d

Collect like terms

–4 – 8 = 4d

–12 = 4d

Divide both side by 3

d = –12 / 4

d = –3

Tₙ = a + (n – 1)d

T₂ = 8 + (2 – 1)(–3)

T₂ = 8 + (1)(–3)

T₂ = 8 – 3

T₂ = 5

Tₙ = a + (n – 1)d

T₃ = 8 + (3 – 1)(–3)

T₃ = 8 + (2)(–3)

T₃ = 8 – 6

T₃ = 2

Tₙ = a + (n – 1)d

T₄ = 8 + (4 – 1)(–3)

T₄ = 8 + (3)(–3)

T₄ = 8 – 9

T₄ = –1

Answer:

2log(base 5)x - 2log(base 5)4

Step-by-step explanation:

The expression which is equivalent to [tex]log_5[/tex] [tex][x/4]^2[/tex] is c) 2[tex]log_5[/tex] x-2[tex]log_5[/tex]  4.

The answer is c. 2[tex]log_5[/tex]  x - 2[tex]log_5[/tex]  4.

We can use the power rule of logarithms to simplify the expression [tex]log_5[/tex]  [tex][x/4]^2[/tex]. The power rule of logarithms states that [tex]log_a[/tex] [tex]b^c[/tex] = c[tex]log_a[/tex] b.

In this case, we have [tex]log_5[/tex]  [tex][x/4]^2[/tex] =[tex]log_5[/tex]  [tex](x/4)^2[/tex] = 2[tex]log_5[/tex]  (x/4).

We can then use the quotient rule of logarithms to simplify the expression further. The quotient rule of logarithms states that [tex]log_a[/tex] (b/c) = [tex]log_a[/tex] b - [tex]log_a[/tex] c.

In this case, we have 2[tex]log_5[/tex]  (x/4) = 2[tex]log_5[/tex]  x - 2[tex]log_5[/tex]  4.

Therefore, the equivalent expression to [tex]log_5[/tex]  [tex][x/4]^2[/tex] is 2[tex]log_5[/tex]  x-2[tex]log_5[/tex]  4.

The other expressions are not equivalent to [tex]log_5[/tex]  [tex][x/4]^2[/tex]. Option a is not equivalent because it has an extra [tex]log_5[/tex]  4 term. Option b is not equivalent because it has a [tex]log_5[/tex]  16 term. Option d is not equivalent because it does not have the -2[tex]log_5[/tex]  4 term.
