The value of x in the triangle extended through W to X is 39.5°.

It should be noted that a triangle has a total angle of 180° and also has three sides. Based on the information given, the following can be deduced:

Angle 1 = 3x - 4.

Angle 2 = 6x + 6

Angle 3 = x + 20

Therefore, the value of x will be gotten by adding the values and equating to 180°. This will be:

3x - 4 + 6x + 6 + x + 20 = 180

4x + 22 = 180

Collect like terms

4x = 180 - 22

4x = 158°

Divide

x = 158/4

x = 39.5°

Answer: 39.5°

Step-by-step explanation:

The simplification of number 17/0 gives the undefined form.

For the given question;

The expression is 17/0

Let us say that 17/0 = x

Its means; 17 = x ×0

17 = 0

But , 17 ≠ 0

As, given expression 17/0 can not be defined by any number.

Thus, 17/0 is an undefined term.

The values of the expressions are

Expression 1

5-(-1 - 2)^2

Evaluate the difference in the expression

So, we have

5 - (-1 - 2)^2 = 5 - (-3)^2

Evaluate the exponent in the expression

So, we have

5 - (-1 - 2)^2 = 5 - 9

Evaluate the difference in the expression

So, we have

5 - (-1 - 2)^2 = -4

Expression 2

|x/x+y| - x^2 + y

When x = 2 and y = -3

Substitute x = 2 and y = -3 in |x/x+y| - x^2 + y

So, we have

|x/x+y| - x^2 + y = |2/2 - 3| - 2^2 - 3

Evaluate the difference in the expression

So, we have

|x/x+y| - x^2 + y = |2/-1| - 2^2 - 3

Evaluate the quotient and the exponent in the expression

So, we have

|x/x+y| - x^2 + y = |-2| - 4 - 3

Remove the absolute bracket

|x/x+y| - x^2 + y = 2 - 4 - 3

Evaluate the difference in the expression

So, we have

|x/x+y| - x^2 + y = -5

Hence, the solutions to the expressions are -4 and -5

for the different values of x, we have found the values of the function f (x) = x² + 2 x + 1.

We are given the function:

f (x) = x² + 2 x + 1

We need to complete the given table of values for x and f (x)

For x = - 3:

f (- 3) = (- 3)² + 2 (- 3) + 1

f (- 3) = 9 - 6 + 1

f (- 3) = 4

For x = - 2:

f (- 2) = (- 2)² + 2 (- 2) + 1

f (- 2) = 4 - 4 + 1

f (- 2) = 1

For x = - 1:

f (- 1) = (- 1)² + 2 (- 1) + 1

f (- 1) = 1 - 2 + 1

f (- 1) = 0

For x = 0:

f (0) = (0)² + 2 (0) + 1

f (0) = 0 + 0 + 1

f (0) = 1

For x = 1:

f (1) = (1)² + 2 (1) + 1

f (1) = 1 + 2 + 1

f (1) = 4

For x = 2:

f (2) = (2)² + 2 (2) + 1

f (2) = 4 + 4 + 1

f (2) = 9

For x = 3:

f (3) = (3)² + 2 (3) + 1

f (3) = 9 + 6 + 1

f (2) = 16

Table:

x     - 3      - 2      - 1      0      1      2      3

y       4         1        0      1      4      9     16

Therefore, for the different values of x, we have found the values of the function f (x) = x² + 2 x + 1.

The value of m in the right triangle to the nearest tenth is 7.2 units.

The figure above is a right triangle.

The right triangles are similar.

Therefore, right triangle ABC is similar to right triangle BDC.

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

Therefore, let's find the value of m using the similar triangle principle,

m / 13 = 4 / m

cross multiply

m × m  = 13 × 4

m² = 52

square root both sides

√m² = √52

The given exponential function represents the growth in function with a percentage increase as 57.3%.

Given we have the exponential function as :

y=8800(1.573)ˣ

it is in the form of: y=k.aˣ

therefore, if a>2 then the function represents growth.

and if a<1 then the function represents decay.

now, x=1.573

1.573 > 1

so, the function represents change in growth.

therefore, 1.573 - 1

= 0.573

= 57.3%

hence the change in growth of the function is increased by 57.3%.

Error might the student have made was in angle 147 as acute angle means angle less than 60°

Acute angles are those that range in size from 0 to 90 degrees and are smaller than 90 degrees. Examples include 60, 30, 45, and other angles. An acute triangle is a triangle with all of its internal angles smaller than 90 degrees. An equilateral triangle, for instance, is an acute triangle because the internal angles are 60°.

Less than 90° of an angle is referred to be an acute angle. An acute angle, for instance, is formed when the time is 11 o'clock between the hour hand and the minute hand. Consequently, acute angles include 30°, 40°, 57°, and others.

Given that : The students are guvena right triangle. One of the acute angles has a measure of 33°. One student saha tbe measure kf the other acute angle is 147°.

Answer:

211a+9x

Step-by-step explanation:

first, calculate the exponents (the number times itself) of each number

9a +81a +121a+9x

the reason they are positive is that a negative times a negative equals a positive ex: -3 x -3 = 9

next, combine the coefficients

starting with the variable for a

9a+81a+121a= 211a

x has no other coefficients so it would remain 9x

so the simplified answer would be

Answer: $3.25 an hour.

Step-by-step explanation: If the server wants to make 184 dollars and they already made 164.50, you subtract 184 by 164.50. 184-164.50= 19.50

That is how much the server made without tips over the course of 6 hours, and we want the amount they made in 1 hour. So we now divide 19.50 by 6. 19.50/6=3.25

The power of the kettle if it takes 70 seconds to boil is 4 kilowatts.

It is given in the question that the  number of seconds that it takes for a kettle to boil, n, is inversely proportional to its power in kilowatts, p.

Also, The equation of proportionality is n = 280/p.

We have to find the power of the kettle if it takes 70 seconds  to boil.

According to the data given in the question, we can write,

n ∝ 1/p

n = k/p

Where k is the constant of proportionality.

Hence, k = 280

n = 280/p

Putting n = 70 seconds in the equation, we get,

70 = 280/p

p = 280/70

p = 4 kilowatts.

The total amount received at the end of 1 year will be 242000

The amount available in Austin's saving account: $100,000

Rate of interest = 142% per year

Simple interest: Simple interest is a quick and simple formula for figuring out how much interest will be charged on loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.

The formula for simple interest is given:

Simple Interest = P*R*T/100

where P = principal amount invested

R = rate of interest per year

T = time in years for which the amount is invested

Substituting the values in the formula we get:

Simple interest = 100000*142*1/100

= 142000

Total amount after 1 year = Principal invested + Simple interest earned

= 100000 + 142000

The correct option regarding the central limit theorem is given as follows:

The average survival time of a large number of guinea pigs has a distribution that is close to normal.

It states that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean given by [tex]\mu[/tex] and standard deviation given by [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, as is the case in this problem, the sampling distribution is also approximately normal, as long as n is at least 30.

For this problem, we have that the distribution is strongly skewed, hence it will only be normal for large sample sizes, and the last option is correct.
