Pythagoras question plz help
motikmotik
From the two right triangles, you can write the following equations using the Pythagorean theorem. Let's call that shared leg in the middle "y"

y^2 + b^2 = a^2
y^2 + c^2 = x^2


y^2 + b^2 = a^2
re-write this to get "y" alone for substitution.
y^2 = a^2 - b^2
substitute (a^2 - b^2) for y^2 in the other equation. y^2 + c^2 = x^2

a^2 - b^2 + c^2 = x^2

Now put in the values given for a,b,c to solve for x

(7.1)^2 - (5.6)^2 + (5.7)^2 = x^2
51.54 = x^2
square root
7.2 = x

Write using exponents. Work from left to right on the grid. x • x .
blondinia [14]

Using exponents x * x is written as x^{2}

<h3>What is exponents?</h3>

Exponents in mathematics is a term that refers to the powers in which a number is raised. Usually the number representing the exponents is usually written upwards in lower font to the left-hand side of the main number or value.

<h3>solving the problem</h3>

x . x is same as x multiplied by x

therefore x . x = x * x

since the x is two the product is written as x^{2}. where the two shows how many times x appeared.

At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x axis?
LuckyWell [14K]
We have that
f(x) = (x – 5)³(x + 2)²

we know that
<span>the roots can touch or cross the x axis

</span>The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.

(x - 5)³ has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.

(x + 2)² has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.

therefore

the answer is
<span>the graph of f(x) touch the x axis for the root x=-2
</span>
see the attached figure
