Answer:

How to graph y=√5 -x is shown in attachment

Step-by-step explanation:

Answer:

  see attached

Step-by-step explanation:

As with any sort of graphing problem, pick values of x and compute the corresponding value of y. Then plot those (x, y) points.

For something like this, it is convenient to choose y and then compute the value of x that goes with it.

 y = 0 = √(5 -x)   ⇒   x = 5 -0² = 5

  y = 1 = √(5 -x)   ⇒   x = 5 -1² = 4

  y = 2 = √(5 -x)   ⇒   x = 5 -2² = 1

  y = 3 = √(5 -x)   ⇒   x = 5 -3² = -4

Once you have plotted the points, draw a smooth curve through them.

Answer:

[tex]\huge\boxed{n=-3}[/tex]

Step-by-step explanation:

[tex]-40-6n=2(1+4n)\\\\\text{Distribute the right side: }\left \{ {{2*1=2} \atop {2*4n=8n}} \right.\\\\-40-6n=2+8n\\\\-40+40-6n=2+8n+40\\\\-6n=42+8n\\\\-6n-8n=42+8n-8n\\\\-14n=42\\\\\frac{-14n}{-14}=\frac{42}{-14}\\\\\boxed{n=-3}[/tex]

Answer:

-3 = n

Step-by-step explanation:

-40 - 6n= 2(1 + 4n)

Distribute

-40 -6n= 2+8n

Add 6n to each side

-40 -6n+6n = 2+8n+6n

-40 = 2+14n

Subtract 2

-40-2 = 2+14n-2

-42 = 14n

Divide by 14

-42/14 = 14/14

-3 = n

Answer:

15-29= -14

(I need the explanation most importantly)

14+(-4) - 8 =10-8=2

(Explanation please)

-8.4 - (19.5.) = - 27.9, (just add them to each other and write -, because both have - in front of them)

(Explanation)

-15 + 8 - (-19.7) = - 7+19,7=12,7 (there is + and - so it will became - 7, and at next there is two - which will turn them into +)

(Explanation)

29.45 - 56.009 - 78.2=−104,759 (all you have to is to put them all together, and than make it 29.45 less, writing - in front of them)

(Explanation)

LAST ONE

45.9 - (-9.2) + 5= 45.9+9.2+5=55.1+5=60.1 (because when there is 2 minus next to each other it will became plus)

Answer:

4y

Step-by-step explanation:

youd have to combine like terms..

Answer:

4y

Step-by-step explanation;

since they have something in common which is y,it is possible to subtract.we would be focusing more on the numbers than letters.The like term which is y just paves a way for these numbers to be subtracted.Hence, 6y -2y= 4y

or you can do it this way also

they have something in common which is y,so we factorise

y(6-2)

y(4)

hence y(4) also means 4 x y= 4y

Answer:

see explanation

Step-by-step explanation:

The first multiplier is the number of terms being added.

The second multiplier is one more than the first multiplier, that is

2 + 4 + 6 + 8 + 10 ← has 5 terms being added and 6 is one more than 5, thus

2 + 4 + 6 + 8 + 10 = 5 × 6

Answer:

The first multiplier is the number of terms being added.

Answer:

30.25 pi

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

11 pi = 2 * pi *r

divide each side by 2 pi

11/2 = 2 ( pi) * r/ ( 2pi)

11/2 = r

We can find the area by

A =  pi * r^2

   =  pi ( 11/2) ^2

   =  pi ( 121/4)

   = pi ( 121/4)

   = 30.25 pi

Answer:

[tex]\Huge \boxed{30.25 \pi}[/tex]

Step-by-step explanation:

The circumference of a circle formula is:

[tex]C= \pi d[/tex]

The circumference is given, solve for d.

[tex]11\pi=\pi d[/tex]

Cancel [tex]\pi[/tex] from both sides.

[tex]11=d[/tex]

The radius is half the measure of the diameter.

[tex]\displaystyle r=\frac{11}{2} =5.5[/tex]

The area of a circle formula is:

[tex]A=\pi r^2[/tex]

Let r = 5.5, solve for the area.

[tex]A=\pi (5.5)^2[/tex]

[tex]A=\pi (30.25)=30.25\pi[/tex]

Answer:

  2 1/4

Step-by-step explanation:

An absolute value cannot be negative, so the negative answer choices are eliminated. The point labeled C is 5 tick marks to the right of 1. We know from the other numbers on the line that 4 tick marks constitutes one unit, so C is 5/4 = 1 1/4 units to the right of 1. Its value is 2 1/4.

Answer:

third, fourth and fifth

Step-by-step explanation:

The y- intercept is the coordinates of the point where the graph crosses the y- axis. At this point the x- coordinate is zero, thus

The function has a y- intercept at (0, 8 ) → fifth

The x- intercepts are the coordinates of the points where the graph crosses the x- axis. At these points the y- coordinate is zero, thus

The function has an x- intercept at (2, 0 ) →third

The function has an x- intercept at (4, 0 ) → fourth

Answer:

y-4=4/5(x-0)

or, 5y-20=4x

or, 4x-5y+20=0 is the required equation

height of building A = 64 meters

height of building B = 87 meters

=====================================================

Explanation:

Refer to the diagram below.

I have added points A,B,C,D to help find the heights needed.

Focus on triangle BAC. This is a right triangle with 58 degrees as one of the known acute angles (angle BAC = 58). Also known is the adjacent side AB = 40. The unknown side we're after is side BC

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

tan(angle) = opposite/adjacent

tan(angle BAC) = BC/AB

tan(58) = BC/40

40*tan(58) = BC

BC = 40*tan(58)

BC = 64.013381161642

BC = 64 meters approximately

This is the approximate height of building A

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

Now focus on triangle DAB

This is another right triangle. The acute angle is now 30 degrees as this is the angle of elevation.

tan(angle) = opposite/adjacent

tan(angle DAB) = DB/AB

tan(30) = DB/40

40*tan(30) = DB

DB = 40*tan(30)

DB = 23.094010767585

DB = 23 meters approximately

Add this onto BC to get

DC = DB+BC

DC = 64+23

DC = 87

Building B has a height of roughly 87 meters

--------

note: a more accurate value would be

DC = DB+BC

DC = 40*tan(30) + 40*tan(58)

DC = 87.107391929227

but when we round this to the nearest meter, we still get DB = 87

Answer:

The correct option is;

Domain: [1.8, 12.76]

Range: [0, 590.90]

Step-by-step explanation:

The given function is h(t) = -4.92·t² + 17.69·t + 575

The maximum height reached is found from equating the derivative of the function to 0 as follows;

d(h(t))/dt = d(4.92·t² + 17.69·t + 575)/dt = -2×4.92·t + 17.69

d(h(t))/dt = 0 gives;

-2×4.92·t + 17.69 = 0

-9.84·t + 17.69 = 0

-9.84·t  =  -17.69

t = -17.69/-9.84 = 1.79 ≈ 1.8

h(1.8) = -(4.92×1.8²) + 17.69×1.8 + 575 = 590.9

Also we have from equating the function to zero

h(t) = -4.92·t² + 17.69·t + 575 = 0

(t - 12.75)(t + 9.2) = 0

Therefore, when t = 12.76 h(t) = 0,

Therefore, we have; the domain which is the set of values of the independent variables is [1.8, 12.76]

The range = [0, 590.90].

Answer:

C on Edge

Step-by-step explanation:

Answer:

Step-by-step explanation:

∠g and ∠f are the interior angles on the same side of the transversal, therefore they're supplementary.

g + f = 180

4x + 3 + x + 17 = 180

5x + 20 = 180

5x = 180 − 20

5x = 160

x=1605=32

g = x + 17 = 32 + 17 = 49

Since ∠g and ∠e are corresponding angles, they're congruent.

g = e = 49

Answer:

1, 5.1, x, 5.1x

Step-by-step explanation:

5.1x can be split into 5.1 * x, therefore, we know that two of the factors are 5.1 and x. Keep in mind that 2 factors of a number are always 1 and the number itself, so we know that 1 and 5.1x are also factors. The final answer is 1, 5.1, x, 5.1x.

============================================

Explanation:

In geometry, a translation is where you slide a point or figure some distance left, right, up or down.

A reflection will mirror a point over a line, or you could mirror a point over another point.

A rotation turns a point around a fixed center point.

A dilation scales the figure to be larger or smaller.

The first three transformations mentioned (translation, reflection, rotation) are known as rigid transformations. They keep the figure the same size and shape. A dilation will keep the same shape, but the size will be different, so the before and after figures are not congruent when you apply a dilation.

Answer:

Write its y-intercept as zero:

[tex]y=m\,x[/tex]

Step-by-step explanation:

If the line is given in slope-intercept form:

[tex]y=m\,x+b[/tex]

make sure that you keep the value of the slope (m) as it is (because you want a line parallel to this one so it has to have the same slope "m", and change the value of "b" to zero, leaving the line with the following form:

[tex]y=m\,x+0\\y=m\,x[/tex]

This forces the line to have its y-intercept at the value zero (origin of coordinates)

Answer:

a.) 98°

Step-by-step explanation:

Angle 5 and angle 8 (82°) are supplementary angles. This means that their sum will make a straight angle of 180°. Make an equation:

[tex]82+x=180[/tex]

Solve for x, the value of angle 5:

[tex]x=180-82\\\\x=98[/tex]

Angle 5 has a  measure of 98°.

Now we know the measure of angle 5. Angle 4 and angle 5 are alternate interior angles, so they are congruent. Therefore, angle 4 has a measure of 98°.

A:3(x+2)=18

Divide each side by 3

3/3(x+2)=18/3

x+2 = 6

This is the same equation as equation B

They will have the same solution since they are the same equation

x+2-2 = 6-2

x = 4

Answer:

You need to multiply/divide both sides by the same constant- they're both equivalent as well.

Step-by-step explanation:

You need to multiply/divide both sides by the same constant- they're both equivalent as well.

This is because solving it you get this

3(x+2)=18

3(x+2) over 3 = 18/3

x+2=6.

That's dividing by a non-zero constant (3).

Answer:

t = -2

Step-by-step explanation:

To solve this equation, we can use algebraic techniques.

2(t + 5) + t = 4 Distribute the 2.

2t + 10 + t = 4 Combine like terms (variables).

3t + 10 = 4 Subtract 10 from both sides of the equation.

3t = -6 Divide by 3 on both sides of the equation.

t = -2
