The hypotenuse of a 45°-45°-90° triangle measures 4 cm. What is the length of one leg of the triangle? 2 cm 2 StartRoot 2 EndRoo

Oxana [17]

Answer:

$2\sqrt{2} cm$

Step-by-step explanation:

In order to solve this you just have to remember the formula for the sides and hypotenuse of the triangle rectangle:

$c^{2} =a^{2} +b^{2}$

Since A and B are equal we will use X to represent them both:

$c^{2} =a^{2} +b^{2}\\4^{2} =x^{2} +x^{2}\\16 =2x^{2}\\8=x^{2} \\x=\sqrt{8}=\sqrt{4*2}=2\sqrt{2}$

ANd by solving the equation we get that the length of the legs of the triangle rectangle with a hypotenuse of 4cm is $2\sqrt{2} cm$

4x 4/4 is equal to 1 , since 4/4 is equal to 1

Grace [21]

Answer:

False, it is equal to 4.

Step-by-step explanation:

The current question asks that 4 x 4/4 is equal to 1, since 4/4 is equal to 1, but this stems from a gross misinterpretation of mathematics.

Although it is true that 4/4 is equal to one, since the 4 parts that make up an integer are completed, when multiplying the number 1 4 times this mathematical operation will result in 4, since 4 x 1 = 4.

Dwight creates a table of values for a function and plots the points. He finds that one y value divided by the next y value prod

Mashcka [7]

we know that

The exponential function is of the form

$f(x)=a^{x}$

where

a is any value greater than $0$

In General:

It is always greater than $0$ , and never crosses the x-axis

It always intersects the y-axis at $y=1$

Its Domain is the Real Numbers

Its Range is the Positive Real Numbers

Examples

Let

$a=3$

1) For $x=2$

$f(2)=3^{2} \\ f(2)=9$

2) For $x=3$

$f(3)=3^{3} \\ f(3)=27$

3) For $x=4$

$f(4)=3^{4} \\ f(4)=81$

4) For $x=5$

$f(5)=3^{5} \\ f(5)=243$

$f(3)/f(2)=\frac{27}{9} \\ =3$

$f(4)/f(3)=\frac{81}{27} \\ =3$

$f(5)/f(4)=\frac{243}{81} \\ =3$

therefore

the answer is the option
