Find the product of the solutions

irina1246 [14]

Answer:

A. -41/15.

Step-by-step explanation:

15x^2 + 23x - 41 = 0

Complete the square to transform the quadratic equation into the form (x – p)2 = q. x2 - 12x - 5 = 7 A) (x - 36)2 = 9 B) (x - 6)

iren2701 [21]

x2 - 12x - 12 = 0

(x - 6)2 - 48 = 0

(x - 6)2 = 48

Hence, the answer is (B).

Prove that the two circles shown below are similar.

s344n2d4d5 [400]

The circles B and D are similar since the radius of the former is as twice as the radius of the latter.

<h3>Are the two circles shown in the figure similar?</h3>

By geometry we know that circles are defined by only one characteristic: radius. If two circles are similar, then the radii must be <em>different</em>. After a quick look at the figure, we conclude that the radii are $r_{B} = 4$ and $r_{D} = 2$ . Hence, the circles B and D are similar since the radius of the former is as twice as the radius of the latter.

After joining two pieces of a picture frame together, a frame maker checks her work by measuring the diagonal (see the illustrat

tigry1 [53]

The diagonal (hypotenuse) is 13 in.

You need to use the Pythagorean Theorem

${a}^{2} + {b}^{2} = {c}^{2}$
then just plug in the numbers and solve for c.

${12}^{2} + {5}^{2} = {c}^{2}$
$\sqrt{169} = c$
13 = c
