What’s the answer ?

Step-by-step explanation:

The y intercept is when x=0 what is the y value.

When x=0, the y intercept is 1.

b. A gradient is the slope of the line. We need to find the rise and run of the line between two points.

Let use points 0,1 and 1,3

Our y values rise by 2 values and our x values change by 1 value so our slope is

\( \frac{2}{1} = 2\)

Answer:

a. At the y-intercept,x=0

This implies the y-intercept=1

b. Taking points (0,1) and (1,3), the gradient of the line is given by (3-1)/(1-0) =2/1 =2

Answer:

21

Step-by-step explanation:

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

AD        AH

-----  =  ---------

AB         AH +y

3        9

---- = ------

10         9+y

Using cross products:

3(9+y) = 9*10

27+3y = 90

3y = 90-27

3y =63

y = 63/3

y = 21

Answer:

y = 21

Step-by-step explanation:

According to the Side Splitter Theorem, if a line parallel to one side of a triangle intersects the other two sides, then this line divides those two sides proportionally.

Therefore, according to the Side Splitter Theorem:

\(\boxed{\sf AD : DB = AH : HC}\)

From inspection of the given triangle, the lengths of the line segments are:

To find the value of y, substitute the given line segment lengths into the proportion and solve for y:

\(\begin{aligned}\sf AD : DB &=\sf AH : HC\\\\3:7&=9:y\\\\\dfrac{3}{7}&=\dfrac{9}{y}\\\\3 \cdot y&=9 \cdot 7\\\\3y&=63\\\\\dfrac{3y}{3}&=\dfrac{63}{3}\\\\y&=21\end{aligned}\)

Therefore, the value of y is 21.

Repeating the 4 digit number is the same as multiplying by 10001, which factors into 73*137 (both prime). The only way 10001n does not have some other prime factor is if n also has only prime factors of of 73 and/or 137. Since 73*137 is 5 digit number, and both 137 and 73 have too few digits, the only product left is 73² = 5329.

According to the dataset, the mean of Dave’s nightly tips is $144.68

The mean of a dataset is the average value of the dataset

Below is how to calculate the mean of Dave’s nightly tips

Mean is calculated using:

Mean = sum of observations/Number of observations

The sum of observations is:

Sum = 100.85 + 166.57 + 135.74 + 148.12 + 113.94 + 190.13 + 235.31 + 102.57 + 124.02 + 142.40 + 108.60 + 110.50 + 163.82 + 183.01

Evaluate

Sum = 2025.58

The number of observations is 14.

So, the mean is:

Mean = 2025.58/14

Divide

Mean = 144.68

Hence, the mean of Dave’s nightly tips is $144.68

The reliability of the given system is 0.4033.

To calculate the reliability of a system, we need to multiply the reliability values of all the components in the system. In this case, we have a system composed of three components with the following reliability values:

Component 1: 0.90

Component 2: 0.90 0.90 0.85

Component 3: 0.85 0.85 0.92

To find the overall system reliability, we multiply these values together:

System reliability = Component 1 reliability x Component 2 reliability x Component 3 reliability

System reliability = 0.90 x (0.90 x 0.90 x 0.85) x (0.85 x 0.85 *x 0.92)

System reliability ≈ 0.90 x 0.6831 x 0.6528 ≈ 0.4033

Therefore, the reliability of the given system is 0.4033.

Answer:

x = 4 sqrt(3)

Step-by-step explanation:

x is not to be confused by the mark on the right angle -- X

The function is the cosine of Y which is 30 degrees.

The cosine of 30o is sqrt(3)/2

cos(30) = adjacent side / hypotenuse = sqrt(3) / 2

The adjacent side is 6

cos(30) = 6/ x = sqrt(3) / 2

6/x = sqrt(3) / 2                      Cross multiply

x * sqrt(3) = 6 * 2

x * sqrt(3)  = 12                       divide by sqrt(3)

x = 12 / sqrt(3)                        Multiply top and bottom by sqrt(3)

x = 12* sqrt(3) / sqrt(3) * sqrt(3)

x = 12 sqrt(3)/ 3                      Divide by 3

In symbolizing truth-functional claims, the word "if" is used to introduce the consequent of a condition, while the phrase "only if" represents the antecedent.

Symbolizing truth-functional claims involves representing statements or propositions using logical symbols. When using the word "if" in a truth-functional claim, it typically introduces the consequent of a conditional statement. A conditional statement is a type of proposition that states that if one thing (the antecedent) is true, then another thing (the consequent) is also true. For example, the statement "If it is raining, then the ground is wet" can be symbolized as "p → q," where p represents "it is raining" and q represents "the ground is wet."

On the other hand, the phrase "only if" is used to represent the antecedent in a truth-functional claim. In a conditional statement using "only if," it states that if the consequent is true, then the antecedent must also be true. For example, the statement "The ground is wet only if it is raining" can be symbolized as "q → p," where p represents "it is raining" and q represents "the ground is wet."

In summary, when symbolizing truth-functional claims, the word "if" introduces the consequent of a condition, while the phrase "only if" represents the antecedent. These terms help express the relationships between propositions in logical statements.

To say "the ball picked up the same amount of speed in each successive time interval" means that the ball's speed increased by an equal amount during each subsequent time period.

When we say that the ball picked up the same amount of speed in each successive time interval, it means that the ball's velocity increased by a consistent value during each subsequent period of time. In other words, the ball experienced the same acceleration in each interval.

For example, let's say we observe the ball's speed at regular intervals of time, such as every second. If the ball's speed increases by 5 meters per second (m/s) in the first second, it would then increase by an additional 5 m/s in the second second, and so on. This demonstrates that the ball is gaining the same amount of speed with each passing interval.

This statement implies a constant or uniform acceleration. In such a scenario, the ball's velocity would increase linearly with time. It is important to note that this assumption may not always hold true in real-world situations, as various factors like friction or external forces can influence the ball's acceleration.

Answer:

The relation between the time and the distance will be:

y = 15x

The graph of the equation y = 15x is attached below.

Step-by-step explanation:

We know that the equation of linear function in two variables in the slope-intercept form is

y = mx+b

where

Let y be the distance

Let t be the time

Given that the object moves 15 meters in 1 second.

Thus, the rate of change or slope = m = 15

As there is no initial condition in our case.

Thus the y-intercept b = 0

Now, substituting m = 15 and b = 0 in the linear function

y = mx+b

y = 15x + 0

y = 15x

Therefore, the relation between the time and the distance will be:

y = 15x

The graph of the equation y = 15x is attached below.

Examples:

Calculate the distance in 1 second

put x = 1 in the equation

y = 15(1) = 15 meters

Calculate the distance in 10 second

put x = 10 in the equation

y = 15(10) = 150 meters

The residual life expectancy of a pug is approximately 2.52 years.

To compute the residual, we need to subtract the observed value (life expectancy of a pug) from the predicted value. In this case, the predicted value is 7.48 years.

Let's assume that the observed value is the average life expectancy of pugs. Please note that life expectancies can vary depending on various factors, and this figure is used here for illustration purposes.

Let's say the observed value is 10 years.

The residual can be calculated as follows:

Residual = Observed Value - Predicted Value

Residual = 10 years - 7.48 years

Residual ≈ 2.52 years

Therefore, the residual is approximately 2.52 years.

Step-by-step explanation:

\( 2 - \dfrac{5}{6}x = \dfrac{3}{8} \)

Multiply both sides by the LCD which is 24.

\( 24(2 - \dfrac{5}{6}x) = 24(\dfrac{3}{8}) \)

\( 48 - 20x = 9 \)

We can generate 2 repeats or groups of 3/8 by adding the sums.

What is summation?

A summation, which is the result of adding two or more numbers or quantities, is also known as a sum. A summation always has an integer number of terms.

If we add 3/8 and 3/8

⇒ 3/8 + 3/8 = 6/8

If we again add 3/8

⇒ 6/8 + 3/8 = 9/8 > 1

It means we can only 2 times allowed to add 3/8 to get 1.

3/8 + 3/8 + x = 1

6/8 + x = 1

x = 1 - 6/8

x = 2/8

3/8 + 3/8 + 2/8 = 1

Therefore, "the maximum group of 3/8 by sum we can get 1 is 2".

The zeros of the polynomial P(x) = x³ + 7x² - x - 7  is  1 , - 1 , - 7 .

In algebraic expressions, exponents may have rational values. A polynomial, on the other hand, is an algebraic assertion with a whole number exponent on any variable. The places where a polynomial turns 0 are referred to as its zeros.

P(x) = x³ + 7x² - x - 7

Now we have to find one zero of given polynomial.

By hit and trial, we get

P(-7) = (-7)³ + 7 (-7)² - (-7) - 7

        = 0

Hence we get one zero = -7

So, -7 is the roots of the equation.

Now, by factorisation :

   P(x) = x³ + 7x² - x - 7

           = x² ( x+7 ) - 1 ( x+3 )

            = (x² - 1) ( x+7 )
