Answer:

  f(-1) = -1

Step-by-step explanation:

x = -1 falls in the middle segment, where -2 < x < 2. So, the applicable function definition is ...

  f(x) = -2x -3

  f(-1) = -2(-1) -3 = 2 -3

  f(-1) = -1

Answer:

A sample size of 1 is never acceptable

Explanation:

A sample size of 1 is simply not statistically significant enough as to reach close to accurate conclusions based on sample data. Statistical tests using just one data point may not be enough to test data variability. Axrule of thumb or best practice is to have at least 10% sample size from the population. It is advised to have at least a sample size of 100 sayvpopulation is 1000 to be able to reach more valid conclusions from sample data.

Step-by-step explanation:

the smaller one has a height of 5

the larger one has aheight of 15

15/5 is 3

Step-by-step explanation:

y = mx + c, where m is the slope of the line and c is the y-intercept.

We have y = 3x - 4 as line L.

Slope of line L = 3

=> Slope of line L2 = -1/3

We have y = -1/3 x + c as our line L2 equation.

When x = 9, y = 5.

=> (5) = -1/3 * (9) + c

=> 5 = c - 3, c = 8

Hence the answer is y = -1/3 x + 8.

The equation of required line [tex]l_2[/tex] is .

Y = mX+c

[tex]Y = \frac{-1}{3} x + 2[/tex]

Given, The equation of straight line L.

Y=3X-4

compareing  with the standard equation of line

Y=mX+c

slope of the equation of line L is [tex]m_1[/tex]= 3.

The product of slopes of two perpendicular lines is -1.

[tex]\rm m_1. m_2 = -1[/tex]

[tex]3.m_2 = -1\\m_2 = \frac{-1}{3}[/tex]

The slope of perpendicular line is  and it passes through the point (9,5). So the equation of the line is

[tex]y = m_2x+c[/tex]

[tex]5 = -\frac{1}{3} . 9 + c[/tex]

5 = -3 + c

5+3 = c

c = 8

Therefore, the equation of required line [tex]l_2[/tex] is .

Y = mX+c

Y = [tex]\frac{-1}{3} X +8[/tex]

Answer:

The percentage increase would be 20%

Step-by-step explanation:

worked it out

The percent increase from 15 to 18 is 20%.

To find the percent increase from 15 to 18, we can use the following formula Subtract the initial value from the final value, then divide the result by the absolute value of the initial value.

Percent Increase = (New Value - Old Value) / Old Value * 100

Using this formula, let's calculate the percent increase:

Percent Increase = (18 - 15) / 15 * 100

Percent Increase = 3 / 15 * 100

Percent Increase = 0.2 * 100

Percent Increase = 20

Therefore, the percent increase from 15 to 18 is 20%.

End behavior means what are the y-values doing as the x-values both increase and decrease without bound.

This is a parabola (degree 2) with a negative leading coefficient (−0.25). Therefore both ends of the graph will be going towards negative infinity.

As x increases, f(x) decreases.

As x decreases, f(x) decreases.

Since the highest degree of the given function, f(x) = -0.25x² – 2x + 1 the end behavior of the graph will be down.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that,

f(x) = -0.25x² – 2x + 1

A polynomial function's end behavior defines how the graph acts as x gets closer. The leading term of the function—that is, the term with the highest n-value for a  × n, where n is a positive integer and an is any nonzero number—allows us to infer the function's final behavior.

The highest degree of the given function is 2. When the function is plotted on the graph we get the graph shows downward behavior when x gets closer.

Thus, since the highest degree of the given function, f(x) = -0.25x² – 2x + 1 the end behavior of the graph will be down.

Given that,

A graph.

To find,

The trans and the reflection.

Solution,

When we slide a figure in any direction, it is called translation or trans.

In this case, option 1 is trans such that ABCD and A'B'C'D' are in same line.

When we flip a figure over a line, it is called reflection.

In this case, option Option 3 is reflection such that ABCD and A'B'C'D' are in opposite direction.

Answer:

The answer is 630 miles using a 30 gallons tank.

Step-by-step explanation:

Well this question is incomplete, but if we are trying to find how many miles can 30 gallons give then the answer would be 630.

Why? Well since 21 miles = 1 gallon then 630 miles = 30 gallons.

Because 21 multiplied by 30 = 630.

Answer:

46 units.

Step-by-step explanation:

To find the perimeter, you need to add up all the sides. Knowing this, we can set up an equation to solve for y.

2(5y + 1) + 2(4y + 3) = 170

10y + 2 + 8y + 6 = 170

18y + 8 = 170

18y = 162

y = 9

Now that we know y = 9, we can solve for vw.

vw = 5(9) + 1

vw = 45 + 1

vw = 46

Therefore, line vw is 46 units.

Answer: VW=11

Answer:

17.44 ft.

Step-by-step explanation:

Given,

The Distance of the hot air balloon: 110 ft

Change in elevation, [tex]\theta_1 = 25^0, \theta_2 = 32[/tex]

We know that,

[tex]\tan \theta = \dfrac{Perpendicular}{base}[/tex]

Now,

[tex]\tan \theta_1 = \dfrac{h_1}{110}[/tex]

[tex]\tan 25^0= \dfrac{h_1}{110}[/tex]

[tex]h_1 = 51.294\ ft[/tex]

[tex]\tan \theta_2= \dfrac{h_2}{110}[/tex]

[tex]\tan 32^0= \dfrac{h_2}{110}[/tex]

[tex]h_2 = 68.736\ ft[/tex]

Rise of balloon = 68.736 - 51.294

                         = 17.442 ft

                         = 17.44 ft

Hence, the rise of the balloon rise is 17.44 ft.
