Answer:

You would multiply the perimeter by three.

Step-by-step explanation:

Since you are tripling the trapezoid, you aslo are tripling each side by three as well, so you would multiply the perimeter by three

An isosceles trapezoid ABCD with height 2 units has all its vertices on the parabola y=a(x+1)(x−5). What is the value of a, if p

horrorfan [7]

Answer:

a = -0.3575

Step-by-step explanation:

The points A and D lie on the x-axis, this means that they are the x-intercepts of the parabola, and therefore we can find their location.

The points A and B are located where

$y=a(x+1)(x-5)=0$

This gives

$x=-1$

$y=5$

Now given the coordinates of A, we are in position to find the coordinates of the point B. Point B must have y coordinate of y=2 (because the base of the trapezoid is at y=0), and the x coordinate of B, looking at the figure, must be x coordinate of A plus horizontal distance between A and B, i.e

$B_x=A_x+\frac{2}{tan(60)} =-1+\frac{2\sqrt{3} }{3}$

Thus the coordinates of B are:

$B=(-1+\frac{2\sqrt{3} }{3},2)$

Now this point B lies on the parabola, and therefore it must satisfy the equation $y=a(x+1)(x-5).$

Thus

$2=a((-1+\frac{2\sqrt{3} }{3})+1)((-1+\frac{2\sqrt{3} }{3})-5)$

Therefore

$a=\frac{2}{((-1+\frac{2\sqrt{3} }{3})+1)((-1+\frac{2\sqrt{3} }{3})-5)}$

$\boxed{a=-0.3575}$

How do you solve the equation -7/8k=21

loris [4]

$- \frac{7}{8} k$ = 21

First, simplify $\frac{7}{8} k$ to $\frac{7k}{8}$ / Your problem should look like: $-\frac{7k}{8}$ = 21
Second, multiply both sides by 8. / Your problem should look like: -7k = 167
Third, divide both sides by -7. / Your problem should look like: k = $\frac{168}{-7}$
Fourth, simplify $\frac{168}{-7}$ to $\frac{168}{7}$ / Your problem should look like: k = $- \frac{168}{7}$
Fifth, simplify $\frac{168}{7}$ to 24. / Your problem should look like: k = -24

Answer: k = -24

10 to the 6th power multiplied by what equals 10 to the 18th power

m_a_m_a [10]

You're asking

(10⁶) times (10^p) = 10¹⁸ .

When you multiply two numbers that have the same base
but different exponents, you just add the exponents.

So        6 + p = 18

Subtract 6 from each side:       p = 12 .

   10⁶ x 10¹² = 10¹⁸ .
