Answer:

The fourth one.

Step-by-step explanation:

By process of elimination, the fourth one is right. First of all, 1st one can't be right because 1 and 2 aren't even the same shape and/or size when they translate, so that can't be it. 2nd one isn't it either because once again, 1 and 3 aren't the same shape and/or size, no matter how much you rotate or move. 3rd one isn't it because while they do translate 6 down, they aren't the same shape since they are both rotated differently, so 3rd one isn't it. Fourth one is it because a reflection can be seen if you do it mentally. If you rotate 2 upside down and compare that to 3, it will be the same shape and translates 6 down like the 4th answer says.

Answer:

  A  7/25

Step-by-step explanation:

The cosine of an angle is equal to the sine of its complement. In a right triangle, angle A is the complement of angle B. So, ...

The Henderson family runs a farm. A portion of the soil on their farm will not be used. What is the area of the portion of the s
Savatey [412]

Answer:

(C)221.5 miles

Step-by-step explanation:

Given a triangle with two sides a and b and an included(an angle between the two given sides) angle \theta,

Area of the Triangle =\dfrac12 ab\sin \theta

a=32$ miles\\b=23 miles\\\theta =37^\circ

Therefore, The area of the portion that will not be farmed

=\dfrac12 \times 32 \times 23 \times \sin \37^\circ\\=221.47\\\approx 221.5$ square miles

The correct option is C.

Hi. I need help with these questions.<br> See image for question.<br> Answer 16 and 17
Irina-Kira [14]

Step-by-step explanation:

16.................................................

<h3>Given</h3>
  • Equation ax² + bx + c = 0
  • One of the roots is twice the other
<h3>To find</h3>
  • Show that 2b² = 9ac
<h3>Solution</h3>

Let the roots be p and q

<u>The sum and product of the roots:</u>

  • p + q = -b/a
  • pq = c/a

<u>The sum of the roots, considering p = 2q,</u>

  • p + q = 2q + q = 3q

And

  • 3q = -b/a ⇒ q = -b/(3a)

<u>The product of the roots, considering p = 2q:</u>

  • pq = 2q(q) = 2q²

And

  • 2q² = c/a

<u>Substitute q with -b/(3a)</u>

  • 2(-b/(3a))² = c/a
  • 2b²/(9a²) = c/a
  • 2b² = 9a²(c/a)
  • 2b² = 9ac

=================================================

17. .................................................

<h3>Given</h3>

Quadratic equation

  • ax² = bx + c = 0, with equal roots
<h3>To find</h3>
  • Show that b² = 4ac
<h3>Solution</h3>

<u>Equal roots means the discriminant is zero:</u>

  • D = √b² - 4ac
  • √b² - 4ac = 0
  • b² - 4ac = 0
  • b² = 4ac
