u(x) = 5x + 3
w(x) = -5x -4
Find the value of u(w(-5)).

Answer:

Step-by-step explanation:

all internal angles in a triangle add to 180 degrees.

77+36=113

180-113=67

we know that the final angle in the triangle is 67 degrees

the left parallel line makes another triangle in the bottom left. we know that one angle is 41 and we just calculated that the other is 67.

41+67=108

180-108=72

so now we know that the small triangle in the bottom left has angles of 41,67 and 72.

all straight lines are 180 degrees, and we just figures out that the left side of the left parallel line is 72 degrees. therefore the other side is 108 degrees.

since they are parallel lines, the left angle of both of them on the bottom line is 72, while the right angle is 108.

this means that x=108 degrees

i hope this is right and it helps if it is correct. really sorry if it is wrong. have a good day :)

Answer:

Assuming that the two line that look like they are parallel are parallel:

x = 5

<(20x) = 100

<(16x) = 80

Step-by-step explanation:

The 2 angles added together equal 180

20x  + 16x = 180  Combine like terms

36x = 180  Divide both sides by 36

x = 5

Substitute 5 for x

20x

20(5) = 100

16x

16(5) = 80

a) The price that is 3 standard deviations above the mean is $18500

b) The price that is 2 standard deviations below the mean is  16000

c) The percentage of buyers who paid between $16,500 and $17,500 is 68%.

d) The percentage of buyers who paid between $17,000 and $18,000 is

47.5%

e) The percentage of buyers who paid less than $16,000 is 2.5%.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

Mean= 17000

standard deviation = $500.

a) The price that is 3 standard deviations above the mean is $

= 17000 + 3 x 500

= 18500

b) The price that is 2 standard deviations below the mean is $

= 17000 - 2 x 500

= 16000

c) The percentage of buyers who paid between $16,500 and $17,500 is

As, This is the bell curve numbers of 1 deviation which 68%.

d) The percentage of buyers who paid between $17,000 and $18,000 is

So,  1/2 of the 2nd deviation, or  95% x 0.5  

= 47.5%

e) The percentage of buyers who paid less than $16,000 is 5% is outside of the 2nd deviation which is half of that or  2.5%.

To find the inverse of a fraction using cross multiplication, you first need to understand what the inverse of a fraction is. The inverse of a fraction is another fraction that, when multiplied by the original fraction, equals 1.

For example, the inverse of 3/4 is 4/3, because 3/4 x 4/3 = 1.

To find the inverse of a fraction using cross multiplication, you will need to use the property that if a/b = c/d, then a x d = b x c. To find the inverse of a fraction, you simply swap the numerator and denominator and multiply them together.

For example, to find the inverse of 3/4, you would swap the numerator and denominator to get 4/3, and then multiply them together to get 1.

So the shortest distance he must walk to return to his house is approximately 10.8 miles.

The man walks 6 miles south and 9 miles east from his house. To find the shortest distance he must walk to return to his house, we need to use the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the man's walk can be represented by a right triangle, where the length of one side is 6 miles (the distance he walked south), the length of the other side is 9 miles (the distance he walked east), and the length of the hypotenuse is the shortest distance he must walk to return to his house.

Using the Pythagorean theorem, we can calculate the length of the hypotenuse as:

hypotenuse = √(6^2 + 9^2) = √(36 + 81) = √117

So the shortest distance he must walk to return to his house is approximately 10.8 miles.

We can say that in geometry, Babylonian mathematicians were able to calculate the area of a trapezoid, suggesting that they were aware of the Pythagorean Theorem.

The Pythagorean Theorem, sometimes known as the Pythagorean Theorem, is the basic Euclidean geometry relationship between a right triangle's three sides. According to this rule, the area of a square with the hypotenuse side equals the sum of the areas of squares with the other two sides. The Pythagorean Theorem, often known as the generic algebraic notation a2 + b2 = c2, states that the square that crosses the hypotenuse of a right triangle opposite the right angle equals the sum of the squares that span the sides of a right triangle.

Other complex mathematical strategies were known to the Babylonians. For example, in geometry, Babylonian mathematicians were able to calculate the area of a trapezoid, suggesting that they were aware of the Pythagorean Theorem long before Pythagoras.

If the right hand side of the equation is non-negative real number, the equation will have two solution that include all real numbers.

An absolute value equation of the form |x| = k (where k is a constant) will have two solutions, one positive and one negative, that are the same distance from 0 on the number line.

To determine if the solutions of the equation include all real numbers, you can examine the value of k. If k is a non-negative real number, then the two solutions of the equation will include all real numbers, because any real number is either positive or negative and the same distance from 0 as k.

For example, if the equation is |x| = 5, the two solutions of the equation are x = 5 and x = -5, which include all real numbers.

On the other hand, if k is a negative real number or a complex number, the equation is not valid and there are no solutions.

Answer:

In a rhombus, opposite angles are equal, therefore:

m∠S = m∠U = a + 62 degrees

And

m∠R = 2a - 80 degrees

The opposite angles of a rhombus are supplementary, meaning they add up to 180 degrees. So,

m∠S + m∠R = 180 degrees

Therefore,

a + 62 + 2a - 80 = 180

Solving for a, we get:

a = 59

So,

m∠S = a + 62 = 59 + 62 = 121 degrees

The amount of each solution that should be mixed together to obtain the desired target solution is;

160 quarts of the solution that contains 3 parts salt to 5 parts water

120 quarts of the solution that contains 2 parts salt to 8 parts water

The parameters are;

Solution A contains 2 parts salt to 8 parts water

Solution B contains 3 parts salt to 5 parts water

Target Mixture contains 3 parts salt to 7 parts water:

Expressing the salt concentration in decimal form;

Solution A: 2/(2 + 8) = 2/10

= 0.20 salt

Solution B: 3/(3 + 5) = 3/8

= 0.375 salt

Mixed Solution: s/(3 + 7) = 3/10

= 0.30 salt

Since target mixture is 280 quarts;

If the amount of 0.375 salt present in mixed solution is denoted by x

Then, the amount of 0.20 salt is expressed as;

y = 280 – x

Using a general mixture equation, we will have;

0.375x + 0.20(280 - x) = 0.30(280)

0.375x + 56 - 0.20x = 84

Subtract 56 from both sides of the equation

0.375x - 0.20x + 56 – 56 = 84 – 56

0.375x - 0.20x = 28

0.175x = 28

Divide both sides of the equation by 0.175

0.175x/0.175 = 28/0.175

x = 160

Thus;

y = 280 – x

y = 280 – 160

y = 120

Therefore,

x = 160 quarts of the solution that contains 3 parts salt to 5 parts water

y = 120 quarts of the solution that contains 2 parts salt to 8 parts water

We have explained all the steps to solve an infinite arithmetic sequence.

What is an arithmetic sequence?

An arithmetic sequence is a sequence of numbers in which each term is the sum of the previous term and a constant called the common difference.

When it comes to solving an infinite arithmetic sequence, you can use the following formulas:

The n-th term of an arithmetic sequence can be represented as a+(n-1)d, where "a" is the first term, "d" is a common difference, and "n" is the position of the term in the sequence.

The sum of the first n terms of an arithmetic sequence is represented as S_n = n/2(2a + (n-1)d), where "a" is the first term, "d" is a common difference, and "n" is the number of terms.

If a sequence is infinite, the sum of all terms can be represented as S_inf = a/(1-r) where "a" is the first term and "r" is the common ratio (r=1+d)

Answer:

a) The function to represent the scenario would be:

f(x) = 56 - 8x

b) To find out how many sips Anna can take before she needs to refill, we need to find when the water bottle is empty.

To do this, we can set f(x) = 0 and solve for x:

0 = 56 - 8x

8x = 56

x = 7

So, Anna can take 7 sips before she needs to refill.

c) A graph to represent this situation would be a straight line with a slope of -8 and y-intercept of 56.

d) The domain of the function is the set of all possible input values, or in this case, the number of sips Anna takes.

As Anna can take any whole number of sips, the domain of the function is the set of all non-negative integers:

{x | x ∈ Z, x ≥ 0}

We can represent how many sips Anna takes from her water bottle with the function y = 56 - 8x. Anna can take 7 sips before she needs a refill. The graph of this function is a straight line that starts at (0, 56) and ends at (7, 0). The domain in set notation is {x|x is an integer and 0 <= x <= 7}.

a) We can represent this scenario with a function, where the amount of water in the bottle depends on how many sips Anna has taken. This is a linear function because each sip Anna takes decreases the amount of water in the bottle by a constant amount. The function could be written as: y = 56 - 8x, where y represents the amount of water in the bottle, and x represents the number of sips Anna has taken.

b) To find out how many sips Anna can take before she needs to refill the bottle, we set y to 0 in our function: 0 = 56 - 8x. Solving for x gives us x = 7. Therefore, Anna can take 7 sips before she needs to refill the bottle.

c) A graph representing this situation would be a straight line starting at (0, 56) on the y-axis, and going down 8 units for each step along the x-axis, until reaching x=7.

d) The domain in set notation for this function would be {x|x is an integer and 0 <= x <= 7}.
