Answer:
the people would save 12 meters
Step-by-step explanation:
If it is a right triangle that has 45,45,90 angles, Than two side lengths would be the same, so there are two 30 meter side lengths. The path is 48 meters long, and the road would be 60 meters long (30+30), so you subtract 48 from 60, and get 12. You would save 12 meters
Question 1: Explain why x = 5 makes 2x_< 10 true but not 2x < 10?

What is the value of the rational expression when x = 5?
The value of the rational function f(x) (x³ + 3x)/(x + 10) on putting the value of x of 5 is 9.3333.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The function f is given below.
[tex]f(x ) = \dfrac{x^3 + 3x }{x+ 10}[/tex]
Then the value of f(x) at x = 5 will be given as

In a National Achievement Test, Joshua obtained a score of 88. In the standardization of the test, μ = 78 and σ = 10. How would you communicate Joshua’s score to his parents? Explain your answer in writing
Using the normal distribution, Joshua's score is communicated as being in the 84th percentile.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 78, \sigma = 10[/tex].
He scored 88, hence X = 88 and his z-score is of:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{88 - 78}{10}[/tex]
[tex]Z = 1[/tex]
[tex]Z = 1[/tex] has a p-value of 0.84.
Hence, Joshua's score is communicated as being in the 84th percentile.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(2x + 3) (x² + x - 2)
(2x)(x²) + (2x)(x) + (2x)(–2) + (3)(x²) + (3)(x) + (3)(–2)
2x³ + 2x² - 4x + 3x² + 3x - 6
2x³ + 5x² - x - 6
Thus,
The final expression is 2x³ + 5x² - x - 6.

nth term of 1,2,4,8,16,32,64,...
Answer:
2^(n-1)
Step-by-step explanation:
To find the nth term of the sequence 1, 2, 4, 8, 16, 32, 64,..., we can observe that each term is obtained by multiplying the previous term by 2. Therefore, the pattern can be described by the formula:
nth term = 2^(n-1)
In this formula, n represents the position of the term in the sequence.
For example: I
If we want to find the 5th term, we substitute n = 5 into the formula:
5th term = 2^(5-1) = 2^4 = 16
So, the 5th term of the sequence is 16.
Find the measurement of the missing angles.
Answer:
Answers to 1 and 5:
Q1 Angle 1: 129 degrees
Q1 Angle 2:116 degrees
Q5 Angle 1: 143 degrees
Q5 Angle 1: 78 degrees
Step-by-step explanation:
I cannot solve all of these, however I can still solve some of them. We know that one side of a straight line is 180 degrees.
Question 1:
If the angle that is next to angle 1 is 51 degrees, then we simply do: 180-51. The result will be 129 degrees.
The angle next to angle 2 is 64. 180-64= 116 degrees.
Question 5:
The angle next to angle 1 is 37. 180-37= 143 degrees.
The angle next to angle 2 is 102. 180-102=78 degrees.

Given the following polynomial, state the Degree, Leading Coefficient, and Constant.
f(x) = 4x^5 + 5x^3 + x^2 +11
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = 4[tex]x^{5}[/tex] + 5x³ + x² + 11
The degree of the polynomial is the value of the largest exponent
Th term with the largest exponent is [tex]x^{5}[/tex] with exponent 5
Thus the degree of the polynomial is degree 5
The leading coefficient is the numeric coefficient of the leading term in standard form.
The leading term is 4[tex]x^{5}[/tex] with leading coefficient of 4
The constant term is the term with no variable attached.
The constant term is therefore + 11

At the beginning of the summer, the water level of a pond is 2 feet below its normal level. After an unusually dry summer, the water level of the pond dropped another 1 1/3 feet. Write an equation to show how far above or below the normal water level the pond is at the end of the summer.
Answer:
x - ( 2 + 1 1/3)
=x- 3 1/3
- 3 1/3 feet
The water level of a pond falls 3 1/3 feet below its normal level.
Step-by-step explanation:
The water level of a pond is 2 feet below its normal level.
The water level of the pond dropped another 1 1/3 feet.
So the total level dropped is 2 + 1 1/3
= 2 + 4/3
= 6+4/3= 10/3 = 3 1/3 feet below the normal.
Suppose the normal is at zero then the level of the pond is at the end of the summer is 0 - 3 1/3 = - 3 1/3 feet.
If we represent the normal by x then the equation becomes
x- 3 1/3 feet to show the water level at the end of summer.
Or it can also be written as
x - ( 2 + 1 1/3)

solve the equation 3/x-4=1/5
Answer:
The very first thing we want to do in this equation is to isolate x on one side (preferably the left side).
3/x - 4 = 1/5
We get rid of any constants first, by performing the inverse property;
The inverse property of subtraction is addition, so we add 4 to both sides:
+4 +4
3/x = 4 1/5
3 is being divided by x, so the inverse operation of division is multiplication. So we multiply by 1/3 on both sides.
x1/3 x1/3
X = 1 4/10 which simplifies to 1 2/5.

Answer:
The First Graph. (-1 and 1 are connected to each other and have open holes)
Step-by-step explanation:
It is the first graph because we are taking the absolute value of x. If we were to plug in -2, we would result in the absolute version, which is 2. There are open holes at the end of the line segment because |x| is less than 1. If we were using greater than or equal to or less than or equal to, then they would be closed holes.

Two solutions
Step-by-step explanation:
x(x+2)=0 has two solutions.

What are the roots of the equation 9x2 – 36x +37
O in simplest a + bí form?
Answer:
x = 2+1/3i or 2-1/3i
Step-by-step explanation:
The equation of interest can be written in vertex form as ...
9(x -2)² +1 = 0
so its solutions can be found by subtracting 1, dividing by 9, taking the square root, then adding 2.
x = 2 ± √(-1/9)
In the desired form, the zeros of the given expression are ...
x = 2 +1/3i or 2 -1/3i
