Find The Value Of X.

Answers

Answer 1

Answer:

x = 12

Step-by-step explanation:

Using the formula (which is a geometric mean):

a       y

---- = -----

x       a

Where a is the altitude (6), x is a projection (x), and y is the other projection (3):

6       3

---- = -----

x       6

Cross multiply:

36 = 3x

12 = x

x = 12

Evaluate functions from their graph g(-9)
Please help my teacher doesn’t teach us anything and just gives us khan academy assignments and I’m really stressing out from this assignment

Answers

the answer is g(-9)=1 and teachers have one job and they can barely do it right

At the coordinate of -9, the value of the function g(-9) will be 1.

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that in the graph the function is varies with the value of the coordinates, at the value of -9 the solution for the function g(-9) will be equal to 1

g(-9) = 1

Hence, the value of the function will be 1.

Ms. Morales showed her geometry student the figure below and told them that DE BC. She asked them to use this information to prove that DE divides AB and AC proportionally. Hannah used the midpoint formula to show that AD=DB and AE=EC. Jaden uses the slope formula to prove that DE and BC have equal slopes. Omar used the distance formula to show that AD/DB=AE/EC. Which student or students used a formula that will help them prove the relationship?

Answers

Answer: Hannah and Omar Only

Step-by-step explanation:

Self explanatory

Hannah and Omar Only used a formula that will help them prove the relationship.

Proportionally

A line drawn parallel to one side of a Δ divides the other two sides in the same ratio.

Given

To prove that DE divides AB and AC proportionally.

Construction: If DE is not parallel to BC, draw DF meeting AC at F.

Proof: In ΔABC, let DF || BC

[tex]\rm \dfrac{AD}{DB}=\dfrac{AC}{FC}\\\\[/tex]

A line drawn parallel to one side of a Δ divides the other two sides in the same ratio.

[tex]\rm \dfrac{AD}{DB}=\dfrac{AE}{EC}\\\\[/tex]

From (i) and (ii), we get

A pair of parallel lines are translated. Which of these could be the result?


Answers

Answer:

c

Step-by-step explanation:

A translation is a transformation that moves every point in a figure in the same direction by the same amount. The correct option is C.

What is translation?

A translation is a transformation that moves every point in a figure in the same direction by the same amount. It is also a sort of transformation in which each point in a figure is moved the same distance in the same direction resulting in the same figure again.

Given that a pair of parallel lines are translated, after the translation, the pair of the line will be still parallel. Therefore, the graph with parallel lines is the correct option.

what is 9 ounces equal to in pounds? please answer in fractions:)

Answers

Answer:

9/16

Step-by-step explanation:

First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:

   

.5625 x 10000

 

   

10000

Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:

   

5625 /10000

The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:

   

5625 ÷ 625 /10000 ÷ 625

And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:

 .5625  =  

   

9 /16

 

   

this would be the answer 0.5625
