Answer:

12.21

Step-by-step explanation:

Step 1: You got to find the distance between your x's

Step 2: You got to find the distance between your y's

Step 3: Apply Pythagorean Theorem:  That is do:

[tex]\sqrt{ (\text{ distance of x})^2+( \text{ distance of y})^2}\\[/tex]

So x distance is 10    (I just did 6-(-4))

So y distance is 7      (I just did 8-1 )

As per the formula, I'm going to square both... Then add those squared results together like so 100+49=149

Last step is the square root...

[tex]\sqrt{149} \approx 12.21 [/tex]

Answer:

1/2

or

0.5

Step-by-step explanation:

you need to get the line in the form of y = mx + b

2x - 4y = 10                  Subtract 3x from both sides

-4y = - 2x + 10              3x on the left disappears. Divide by - 4

-4y/-4 =-2x/-4 +10/-4    Do the division

y = (2/4)x - 2.5

y = (1/2)x - 2.5

The slope is the number in front of the x

y = 0.5x - 2.5

y=0

5x=80

x=8-0/5=16

Answer:

Step-by-step explanation:

The answer is B.16

Since the equation is 5x+8y=80

There are no parents so it equation will turn into 5x+8(0)=80, AKA, 5x=80

Using algebra, 5x=80 will x=80/5

which is 16

For this case we have the following expression:

[tex]a + b[/tex]

We must evaluate the expression to:

[tex]a = 2\\b = 3[/tex]

Substituting the values in the expression we have:

[tex]2 + 3[/tex]

Equal signs are added and the same sign is placed.

So:

[tex]2 + 3 = 5[/tex]

Finally, the value of the expression is 5.

Answer:

[tex]a + b = 5[/tex]for[tex]a = 2[/tex] and[tex]b = 3[/tex]

Answer: "The true mean height of the giraffes is less than or equal to 15 feet".

Step-by-step explanation:

A hypothesis in a statement that is made about a statistical parameter of a population.

A null hypothesis [tex]H_0[/tex] is usually the hypothesis that is tried to reject by an alternate hypothesis [tex]H_a[/tex]

In this case  [tex]H_a[/tex] is:

"The true mean height of the giraffes is more than 15 feet".

Therefore, for this case, the null hypothesis must be:

 "The true mean height of the giraffes is less than or equal to 15 feet".

Answer:

[tex]x^2-10x+25[/tex]

Step-by-step explanation:

We have been given an expression [tex]x^2-10x+[/tex]. We are asked to convert our given expression into perfect-square trinomial.

We know that an equation in form [tex]x^2+bx+c[/tex] is a perfect square, if [tex]c=(\frac{b}{2})^2[/tex]

To convert our given expression into perfect-square trinomial, we need to add [tex](\frac{10}{2})^2[/tex] to our given expression.

[tex](\frac{10}{2})^2=5^2=25[/tex]

Therefore, our perfect square trianominal would be [tex]x^2-10x+25[/tex].

Answer:

2pi

Step-by-step explanation:

period for sin is 2pi/b

its only x theres 1 before x so its 1x=b

2pi/1

= 2pi

The period of  function f ( x ) = sin ( x ) is 2π.

The sine function ( sin ( x ) ) is a periodic function, which means it repeats its values in regular intervals. The period of sin(x) is the length of one complete cycle of the function before it starts repeating itself.

The period of the function f ( x ) = sin( x ) is 2π.

In the case of sin ( x ), it completes one full cycle ( from 0 to 2π ) every 2π units. Therefore, the period of f ( x ) = sin ( x ) is 2π.

Answer:

The new function is g(x) = Ix - 5I - 7 ⇒ answer C

Step-by-step explanation:

* Lets revise the translation of a function

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) – k

* Now lets solve the problem

∵ f(x) = IxI

∵ f(x) is shifted 5 units to the right

∵ If the function f(x) shifted to the right  by h units

∴ g(x) = f(x - h)

- Change IxI to Ix - 5I ⇒ (1)

∵ f(x) is shifted 7 uints down

∵ If the function f(x) shifted down  by k units

∴ g(x) = f(x) - k

- Change f(x) to f(x) - 7 ⇒ (2)

- From (1) and (2) the new function is:

 g(x) = Ix - 5I - 7

* The new function is g(x) = Ix - 5I - 7

!!

Step-by-step explanation:

The average rate of change over the entire slide is [tex]\( \frac{1}{10} \)[/tex] feet per foot.

To find the average rate of change over the entire slide, we need to calculate the change in height divided by the change in distance over the entire slide.

Let's denote:

- [tex]\( h_1 \)[/tex] as the initial height (when x = 0),

- [tex]\( h_2 \)[/tex] as the final height (when x = 20).

Given that the height of the slide is 2 feet when ( x = 20 ), we have:

[tex]\[ h_2 = 2 \, \text{feet} \][/tex]

We also know that the height of the slide is 0 feet when ( x = 0 ), so:

[tex]\[ h_1 = 0 \, \text{feet} \][/tex]

Now, the change in height ([tex]\( \Delta h \)[/tex]) over the entire slide is:

[tex]\[ \Delta h = h_2 - h_1 = 2 \, \text{feet} - 0 \, \text{feet} = 2 \, \text{feet} \][/tex]

The change in distance ([tex]\( \Delta x \)[/tex]) over the entire slide is simply the distance traveled, which is:

[tex]\[ \Delta x = 20 \, \text{feet} \][/tex]

The average rate of change over the entire slide ([tex]\( \text{Avg ROC} \)[/tex]) is then:

[tex]\[ \text{Avg ROC} = \frac{\Delta h}{\Delta x} \][/tex]

[tex]\[ \text{Avg ROC} = \frac{2 \, \text{feet}}{20 \, \text{feet}} \][/tex]

[tex]\[ \text{Avg ROC} = \frac{1}{10} \][/tex]

The average rate of change of the slide height is calculated as 0.1 feet per foot, indicating that the height increases by 0.1 feet for every foot along the slide.

Step by step calculation:

The average rate of change of a function over an interval is calculated using the formula:

       Average Rate of Change = (2 - 0) / (20 - 0) = 2 / 20 = 0.1 feet per foot

This means the height increases by 0.1 feet for every foot traveled along the length of the slide.

Step-by-step explanation:

Answer:

y=5 is horizontal

(-4,5) is on the line

Step-by-step explanation:

y= a number is always a horizontal line

x= b number is always a vertical line

So y=5 is horizontal and it includes every single ordered pair with a y-coordinate of 5. So it contain the ordered pair (-4,5).

So there are two statements.

The correct statements are :

The graph of y = 5 is a vertical line.

The point (-4, 5) lies on the line.

An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.

So the line passes through ( -4,5)

Answer:

Option C is correct.

Step-by-step explanation:

We need to find the pattern as the exponent decreases.

the first value in the table is 125.

if we divide 125 by 5 i.e 125/5 we get 25

the next value in the table is 25

if we divide 25 by 5 i.e 25/5 we get 5

the next value in the table is 5

if we divide 5 by 5 i.e 5/5 we get 1

the next value in the table is 1

if we divide 1 by 5 i.e 1/5 we get 1/5

the next value in the table is 1/5

if we divide 1/5 by 5 i.e 1/5*5 we get 1/25

the next value in the table is 1/25

So, the pattern is if we divide the previous value by 5 we get the next value in the table.

Answer:

You start at the bottom

Distance, often assigned the variable d, is a measure of the space contained by a straight line between two points. Distance can refer to the space between two stationary points (for instance, a person's height is the distance from the bottom of his or her feet to the top of his or her head) or can refer to the space between the current position of a moving object and its starting location.

Answer:

C

Step-by-step explanation:

Given the inequality

(x - 3)(x + 5) ≤ 0

Find the zeros by equating to zero

(x - 3)(x + 5) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x + 5 = 0 ⇒ x = - 5

Thus the domain is split into 3 intervals

--------------------------------------------------------------

- ∞ < x ≤ - 5 → (1)

- 5 ≤ x ≤ 3 → (2)

3 ≤ x < + ∞ → (3)

Select a test point in each interval and check validity

x = - 10 → (- 13)(- 5) = 65 > 0 ← not valid

x = 0 → (- 3)(5) = - 15 < 0 ← valid

x = 10 → (7)(15) = 105 > 0 ← not valid

Solution is { x | - 5 ≤ x ≤ 3 }

We have as data the following points:

[tex](x1, y1) = (2,3)\\(x2, y2) = (- 2, -4)[/tex]

Substituting in the formula we have:

[tex]m = \frac {-4-3} {- 2-2}[/tex]

Let child one = x

Let child two = y

Let child three = z

Equations

x^2 + y^2 + z^2 = 100

xy + xz + yz = 150

Solution

There's a trick here. The square of their weights added together is equal (with some modification) to the given conditions. Start by squaring (x+y+z).

(x + y + z)^2 = x^2 + y^2 + z^2 + 2xy + 2xz + 2yz

Take out 2 as a common factor from the last three terms.

(x + y + z)^2 = (x^2 + y^2 + z^2+ 2(xy + xz + yz) )

Substitute the given conditions into the equation. (x^2 + y^2 + z^2) = 100 and 2*(xy + xz + yz) = 2 * 150

(x + y + z)^2 = 100 + 2*150

(x + y + z)^2 = 100 + 300

(x + y + z)^2 = 400

Take the square root of both sides.

sqrt(x+y+z)^2 = sqrt(400)

x + y + z = 20

Note

This answer tells you nothing about the values of x y and z. On the other hand it does not ask for the values of x y and z.
