3xyz + 7xyz + 9xyz

Answers

Answer:

19xyz

Step-by-step explanation:

First, let us just forget about the xyz at the end of each number. Now, we just have the simple addition problem 3 + 7 + 9. First. let us do 3 + 7, which gives us 10. Now, let us take our 10 and add the 9 to it. 10 + 9 is 19. Now, we can add our xyz back to the equation. Now, we have 19xyz. As we do not know anything about what x, y, or z equals, nothing further can be done with this equation. Therefore, the answer is 19xyz.

A water park has pools, slides, and rides that, in total, make use of 8.7\times 10^{6}8.7×10 6 gallons of water. They plan to add a ride that would make use of an additional 4.8\times 10^{3}4.8×10 3 gallons of water. Use scientific notation to express the total gallons of water made use of in the park after the new ride is installed.

Answers

Answer:

as i said i would go with 93-51=42

Step-by-step explanation:

8.7*10.6=92.22 and 8.7*10+6=93

4.8*10.3=49.44 and 4.8*10+3=51

so i am thinking that you would add 93+51 which equals 144...

or you could try 93*51 but your gunna get 4,743

or try 93-51 which is 42

or try 93 diveded by 51 which is 1.8235294117647058

I would go with 93-51=42!

What is Algebra?

Algebra is the study of mathematical symbols, while logic is the manipulation of those signifiers.

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction is referred to as the PEMDAS principle. To answer the problem properly and accurately, this rule must be followed.

A water park uses 8.7 × 10⁶ gallons of water in total for its pools, slides, and attractions. They intend to include a ride that will use an extra 4.8 × 10³ gallons of water.

After the new attraction is constructed, the park will have used the total gallons of water is given as,

⇒ 8.7 × 10⁶ + 4.8 × 10³

⇒ 8700 × 10³ + 4.8 × 10³

⇒ 8704.8 × 10³

After the new attraction is constructed, the park will have used 8704.8 × 10³ total gallons of water.

The speed of light is 299 792 458 m / s


Which decadic units can you round to so that only one non-zero digit is produced?

Answers

Answer:

299,792,460

Step-by-step explanation:

just round to the nearest 10th

Answer:

The speed of light is exactly 299,792,458 m/s because that is how a meter is defined. A meter is defined as the distance light travels in 1/299792458 seconds in vacuum. Why was this particular number chosen? To keep the definition of meter consistent with the old standard which was an actual physical bar. The length of this bar was arbitrary though.

Find the equation of the line through the point ( 3 , − 7 ) that is perpendicular to the line with equation y = x − 12 .

Answers

Answer:  y = -x - 4

Step-by-step explanation:

A perpendicular line has a slope that is the negative inverse of the reference line, which is y = x-12.  The slope here is 1, so the negative inverse would be -1/1, or -1.  The perpendicular line would therefore be:

y = -1x + b

We can find b by using the given point (3,-7) as a solution:

y = -1x + b

-7 = -1*3 + b

b = - 4

The equation is therefore   y = -x - 4

The size of a white tablet is 0.000005 m and that of a red tablet is 0.0000275 m.Find their ratios and Compare their sizes

Answers

A ratio will just be trying to find whole number versions of these decimals and then compare them side by side (always divide the larger number by the smaller number).

Therefore:

[tex]\frac{0.0000275}{0.000005}=5.5=\frac{5.5}{1}[/tex]

However, this isn't a proper ratio. Generally, ratios are whole numbers. Since it's 5.5, we can easily make this a whole number by multiplying it by 2. Keep in mind though, what we do to one number we do to the other! So:

[tex]\frac{2}{2}(\frac{5.5}{1})=\frac{2*5.5}{2*1}=\frac{11}{2}[/tex], technically this is a better format since it's whole numbers, but it gives you the ratio (11:2) which is a bit tougher to interpret than (5.5:1)

Therefore, the ratio we'll use is 5.5:1 for simplicity's sake:

From this ratio, we can see that the red tablet is 5.5x the size of the white tablet.

Evaluate the following integral:​

Answers

[tex]\large\underline{\sf{Solution-}}[/tex]

Given integral is

[tex]\rm :\longmapsto\:\displaystyle\int\rm \frac{ {x}^{e - 1} + {e}^{x - 1} }{ {x}^{e} + {e}^{x} } \: dx[/tex]

To evaluate this integral, we use Method of Substitution.

So, Substitute

[tex]\rm :\longmapsto\: {x}^{e} + {e}^{x} = y[/tex]

[tex]\rm :\longmapsto\: \dfrac{d}{dx}({x}^{e} + {e}^{x}) = \dfrac{d}{dx}y[/tex]

[tex]\rm :\longmapsto\: {ex}^{e - 1} + {e}^{x} = \dfrac{dy}{dx}[/tex]

[tex]\rm :\longmapsto\:e( {x}^{e - 1} + {e}^{x - 1}) = \dfrac{dy}{dx}[/tex]

[tex]\rm :\longmapsto\:({x}^{e - 1} + {e}^{x - 1})dx = \dfrac{dy}{e}[/tex]

So, on substituting all these values in above integral, we get

[tex]\rm \:  =  \: \displaystyle\int\rm \frac{dy}{e \: y} [/tex]

[tex]\rm \:  =  \:\dfrac{1}{e} \displaystyle\int\rm \frac{dy}{ y} [/tex]

[tex]\rm \:  =  \:\dfrac{1}{e}log |y| + c[/tex]

[tex]\rm \:  =  \:\dfrac{1}{e}log \bigg| {x}^{e} + {e}^{x} \bigg| + c[/tex]

Hence,

[tex]\rm :\longmapsto\:\boxed{\tt{ \displaystyle\int\rm \frac{ {x}^{e - 1} + {e}^{x - 1} }{ {x}^{e} + {e}^{x} } \: dx = \frac{1}{e}log \bigg| {x}^{e} + {e}^{x}\bigg| + c}}[/tex]

Answers

Answer:

15, 16, 17

Step-by-step explanation:

let the consecutive numbers be n , n + 1 , n+ 2 , then

n + n + 2 = 32 ( sum of first and third )

2n + 2 = 32 ( subtract 2 from both sides )

2n = 30 ( divide both sides by 2 )

n = 15

n + 1 = 15 + 1 = 16

n + 2 = 15 + 2 = 17

The 3 numbers are 15, 16, 17

Step-by-step explanation:

let the 1st and 2nd consecutive number be

x , x + 1 , x + 2

their sum = 32

so, x + x + 2 = 32

2x + 2 = 32

2x = 32 - 2 = 30

x = 30/2 = 15

so,

1st and 3rd consecutive number is

x = 15

x + 2 = 15 + 2 = 17

as they are consecutive number so 2nd number is 16

and a/q sum of 1st and 3rd number is 32

15 + 17 = 32

Write the equation of a line perpendicular to 5x−9y=−8 that passes through the point ​(−5​,8​).

Answers

Answer:  y = -(9/5)x - 1

Step-by-step explanation:

Rewrite the equation in standard form:  y = (5/9)x+(8/9).  [y=mx+b]

A line perpendicular to this would have a slope that is the negative inverse of the original slope (5/9), which would make it -(9/5).  The y-intercept would also change, but we don't know the value, yet.  For now, we'll use "b" for the y-intercept.  This results in a perpendicular line:

y = -(9/5)x + b

We can calculate b, the y-intercept, by using the point (-5,8) and solving for b.

8 = -(9/5)*(-5) + b

8 = (9) + b

b = -1

The line perpendicular to 5x−9y=−8 that passes through the point ​(−5​,8​) is

y = -(9/5)x - 1

Answers

Step-by-step explanation:

your teacher forgot to mention if the dilation is based on the origin (0, 0).

I assume this is what was meant, but it has to be explicitly specified to be sure.

but if things are as assumed, then the scaling factor is just multiplied into the point coordinates to get the result :

H' = (-2×2, 6×2) = (-4, 12)
