Answer:

x = 10

Explanation:

Using Pythagoras Theorem:

  • a² + b² = c²

Solve:

8² + 6² = x²

x² = 64 + 36

x² = 100

x = √100

x = 10

<h3><u>Answer</u><u>:</u><u>-</u></h3>

10

<h3><u>Formula </u><u>used</u><u>:</u><u>-</u></h3>

Pythagoras theorem

(a² + b² = c²)

<h3><u>Explanation</u><u>:</u><u>-</u></h3>

Let ,

a = 8

b = 6

c = x

Using Pythagoras theorem,

=> 8² + 6² = x²

=> x² = 64 + 36

=> x² = 100

=> x = √100

=> x = 10

Hence, the length of x is 10.

How to memorize multiplication tables in one day?
padilas [110]
You cannot memorize a whole multiplication chart in one day, but if you go online and search multiplication stories, there may be some stories to help you memorize your facts quicker depending on your learning style. Also try and remember that any number times any number is just that number being added over and over again a certain amount of times. For example: 3*4= 3+3+3+3 Hope this helps :)

Please help me I need it please answer it correctly please help me please
jeka57 [31]

On the 7th, Andi had $48 in her account. We want to find when she had $92 less than what she had on the 7th.

First, let's find out how much $92 less is:

48 - 92 = -44

We are looking for when Andi had $-44 in her account. Looking at the number line, the day Andi had $-44 in her account was on the 14th.

The correct answer is C. The 14th.

Hope this helps!! :)

Find the missing length. The triangles are similar.
hodyreva [135]

Answer:

182

Step-by-step explanation:

First, we can say that ∠ACB and ∠BCF are opposite angles because they are not next to each other and are formed by intersecting lines. Therefore, ∠ACB = ∠BCF

Next, angles correspond with the side opposite of it. This means that, for example, ∠ACB corresponds with line AB and ∠BCF corresponds with line BF. Because ∠ACB and ∠BCF are equal and the triangles are similar, we can say that their corresponding sides have a ratio with each other. Similarly, ∠CAB corresponds to CB, ∠ABC corresponds to AC, ∠CWV corresponds to CV, and ∠CVW corresponds to CB.

Because the triangle CVW is isosceles, we can say that the angles whose corresponding sides are equal are equal as well, so ∠CAB = ∠ABC and ∠CVW = ∠CVW. Next, because ∠ACB and ∠BCF are equal and correspond to each other, and the other two angles in each triangle are equal to each other, we can say that the other two angles must be equal. Another way of putting this is like this:

Say that x = ∠CAB. Then,

∠CAB + ∠ABC + ∠ACB = 180

x + x + ∠ACB = 180

2x + ∠ACB = 180

subtract ∠ACB from both sides

180 - ∠ACB = 2x

Similarly, if y = ∠CWV,

180 - ∠WCV = 2y. Therefore, 2y=2x and y=x, so ∠CAB = ∠ABC = ∠CWV = ∠CVW.

Given this, we can say that sides CV and CW correspond with BC and AC. This means that the ratio between, for example, CV and BC is equal to the ratio between CW and AC. Therefore,

CV/BC = CW/AC

84/182 = 84/?

Filling in the blank, 84/182 is equal to 84/182, so ? = 182

A quadratic function is described by the equation f(x) = (x - 3) ^ 2 Which statement about the graph of the function is true?
Bond [772]

Answer: A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis

Step-by-step explanation:

Remember, a quadratic function which has roots x = a, and x = b, can be written as:

p(x) = A*(x - a)*(x - b)

Where A is the leading coefficient. This is the factorized form of a quadratic.

We have the function:

f(x) = (x - 3)^2

Now, we could rewrite this as:

f(x) = (x - 3)*(x - 3) = 1*(x - 3)*(x - 3)

Then we wrote f(x) in its factorized form, from this, we can see that the roots of the function are x = 3, and x = 3 (we have the same root two times)

Then the only root of f(x) is x = 3.

Remember that a root (also called a zero) is the value of x where the function intersects the x-axis. then the correct option here is:

A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis
