6.4

Step-by-step

You have to use the Pythagorean Theorem. a^2+b^2=c^2

4^2+5^2=c^2

16+25=41

The square root of 41 is 6.40312...

Round that to the nearest tenth to get 6.4

Write the equation in standard form for the circle with center (-7,5) and radius 8
Ivenika [448]

Answer:

64 = (x+7)^2 + (y-5)^2

Step-by-step explanation:

Equation of a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So the equation is: 64 = (x+7)^2 + (y-5)^2

What are the solutions of the equation (x 2)2 – 2(x 2) – 15 = 0? use u substitution to solve. x = –7 and x = 1 x = –5 and x = 3
Vitek1552 [10]

The solutions to the equation \rm (x + 2)^{2} - 2(x + 2) - 15 = 0 are 3 and -5.

<h3>What is the solution to the equation?</h3>

To solve any equation is to find the solution of the given equation which satisfied the equation.

The given expression is \rm (x + 2)^{2} - 2(x + 2) - 15 = 0

let u = (x +2)

then the equation becomes

\rm u^{2} - 2u - 15 = 0

by factorizing, we get

(u + 3)(u - 5) = 0

u + 3 = 0, u = -3

u - 5 = 0, u = 5

Since, u = x + 2

So, x + 2 = 5, x = 3

x + 2 = -3, x = -5

Therefore, the solutions to the equation are 3 and -5.
