Answer:

8.94 m

Step-by-step explanation:

Use the Pythagorean Theorum - [tex]a^2 + b^2 = c^2[/tex]. Use leg 1 as a, leg 2 as b, and the third side as c.

We know leg 1 is 4, and that leg 2 is twice as long as leg 1...

[tex](4)^2 + (4*2)^2 = c^2[/tex]

Now, we use the Order of Operations to find [tex]c^2[/tex]...

[tex]4^2+8^2=c^2\\16+64=c^2\\80=c^2[/tex]

Now, we find the square root of [tex]c^2[/tex] to find c...

[tex]\sqrt{80} =8.94[/tex]

So, the length of the third side is 8.94 m.

Answer:

I would say the opposite function would either be a linear function, or have all the terms on one side multiplied by -1

The main features of the opposite function of the quadratic equation are; Reflection and Symmetrical

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are Given a quadratic function and its key features

To Determine: what key features its opposite function will have

The opposite function or inverse functions are reflections of each other over the straight line y = x.

We will find the inverse by switching x and y in the equation as;

f(x) = x² + 5

The inverse would be

x = √f(x) - 5

Once graph those two functions, that will see that they're symetrical that has y=x line by its middle line.

according to my equation it is 61.6

Answer:

Volume is equal to

L×W×H

=(10×9×7)cm

=90×7

=630

The volume of the prism is 980cm3.

We are given that;

The dimensions= 4*7*9*2*10cm

Now,

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

The volume of a rectangular prism=Length X Width X Height

Volume of upper prism;

=5*4*40

=800cm3

Volume of lower prism;

=2*9*10

=180cm3

Total volume= upper volume + lower volume

=980cm3

Therefore, by the rectangular prism the answer will be 980cm3.

Answer:

y + 2.3 = 0.45x

y = 0.45x - 2.3

-2y = 4.2x - 7.8

-2(0.45x - 2.3) = 4.2x - 7.8

-0.90x + 4.6 = 4.2x - 7.8

-0.90x - 4.2x = -7.8 - 4.6

-5.1x = - 12.4

x = -12.4 / -5.1

x = 2.4

y + 2.3 = 0.45x

y = 0.45(2.4) - 2.3

y = 1.08 - 2.3

y = -1.2

solution is : (2.4, - 1.2)

i use same program

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

Explanation:

Extend segment MN such that it intersects side ST. Mark the intersection as point A. See the diagram below.

We're given that angle MNT is 72 degrees. The angle TNA is equal to 180-(angle MNT) = 180 - 72 = 108 degrees, since angles MNT and TNA add to 180.

For now, focus entirely on triangle TNA. We see from the diagram that T = 34 and we just found that N = 108. Let's find angle A

A+N+T = 180

A+108+34 = 180

A+142 = 180

A = 180-142

A = 38

So angle NAT is 38 degrees.

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

Since segment MA is an extension of MN, and because MN || SQ, this means MA is also parallel to SQ.

We found at the conclusion of the last section that angle NAT was 38 degrees. Angles QST and NAT are corresponding angles. They are congruent since MA || SQ. This makes angle QST to also be 38 degrees

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

The angles QSR and QST are a linear pair, so they are supplementary

(angle QSR) + (angle QST) = 180

angle QSR = 180 - (angle QST)

angle QSR = 180 - 38

angle QSR = 142 degrees

Answer:

3.2 liters

Step-by-step explanation:

The first thing we want to do is find the amount of water it leaks hourly

To do so we divide the amount of water it leaks in 3 hours ( .48 ) by 3

.48/3 = .16

So the faucet leaks .16 liters per hour

Now to find how much water the faucet leaks in 20 hours

To do this we simply multiply 20 by the hourly leakage amount (.16)

.16 * 20 = 3.2

So in 20 hours the faucet would have leaked 3.2 liters of water

Answer:

3.2 liters of water :)!

Step-by-step explanation:

If 0.48 every 3 hours we can do 0.48/3 to find the amount it loses every hour.

0.48/3=0.16

Then if we multiply 0.16 by 20 we will get the amount it loses in 20.

0.16x20=3.2

Hence, it loses 3.2 liters of water every 20 hours.

Hope this helps:)!

The given relation {(2,1), (4,2) (6,3) (8,4)} is one to many relation.

The other solution for this problem is given below.

The pattern is the sum of the two numbers plus the previous sum, i.e.

12 = 2+5 +(5)

21 = 3+6+ (12)

40 = 8+11 +21

These type of questions are part of reasoning and comes in random competitive exams which have multiple choice questions and therefore you have more than you want.

First , you need to multiply both numbers and then add the first number.

Therefore, 1+4= 1x4+1=5

2+5=2×5+2=12

3+6=3×6+3=21

A many-to-one relationship is where one entity (typically a column or set of columns) contains values that refer to another entity (a column or set of columns) that has unique values.

Hence,8+11=8×11+8=96

The other solution for this problem is given below.

The Solution for this is

1+4=5

1(4+1)=1(5)=5

2+5=12

2(5+1)=2(6)=12

3+6=21

3(6+1)=3(7)=21

Therefore we get,

8+11=8(11+1)=8(12)=96.

Therefore the given relation is any one to many relation.

Given:

The polygon in the given figure are similar.

To find:

The missing side length.​

Solution:

We know that the corresponding sides of similar figures are proportional.

The given polygons are similar, so the their corresponding sides are proportional.

[tex]\dfrac{x}{15}=\dfrac{32}{40}=\dfrac{32}{40}[/tex]

So, the missing values in the equation of proportion are 15, 40, 32 respectively.

On solving the above equation, we get

[tex]\dfrac{x}{15}=\dfrac{4}{5}=\dfrac{4}{5}[/tex]

[tex]\dfrac{x}{15}=\dfrac{4}{5}[/tex]

[tex]x=\dfrac{4}{5}\times 15[/tex]

[tex]x=12[/tex]

f(x) = 1/2x + 6

Step-by-step explanation:

So before we even look at the first given formula, let's use the second formula: f(x) = -5.

Plug this formula into the x:

0 <= -5 <= 7

Is this true? Is -5 greater than or equal to 0 and less than or equal to 7?

No, this is false.

So the formula, f(x) = -5, is not the graph of f.

825 in^3

Step-by-step explanation:

The volume of a cylinder is

V = pi r^2 h  where r is the radius and h is the height

We are given the diameter of 10

The radius is 1/2 of the diameter of 1/2 (10) = 5

V = (3) * (5)^2 * 11

V = 3( 25)*11

   = 825 in^3

Answer: 825 in³

Step-by-step explanation:

Volume = πr²h, where:

Therefore, the volume of this cylinder can be calculated as:
