ANSWER

$\frac{x - 4}{2x - 2}$

EXPLANATION

The given expression is;

$\frac{2 {x}^{2} + 5x + 3}{ {x}^{2} - 3x - 4} \div \frac{4 {x}^{2} + 2x - 6}{ {x}^{2} - 8x + 16}$

We factor to obtain;

$\frac{(x + 1)(2x + 3)}{(x - 4)(x + 1)} \div \frac{2(x - 1)(2x + 3)}{(x - 4)(x - 4)}$

Multiply by the reciprocal of the second fraction

$\frac{(x + 1)(2x + 3)}{(x - 4)(x + 1)} \times \frac{(x - 4)(x - 4)}{2(x - 1)(2x + 3)}$

Cancel out common factors to get,

$\frac{1}{1} \times \frac{(x - 4)}{2(x - 1)}$

$\frac{x - 4}{2x - 2}$

If cos(t) = 2/7 and t is in the 4th quadrant, find sin(t).

Yuliya22 [10]

We can use the Pythagorean Trigonometric Identity which says:
$sin^2(t)+cos^2(t)=1$

Since we need to find sin(t), we have to solve for it:
$sin(t)= \sqrt{1-cos^2(t)}$

Let's plug in the given cos(t) value:
$sin(t) = \sqrt{1-cos^2( \frac{2}{7})}$

And solve sin(t):
$sin(t) = \sqrt{1- \frac{4}{49} } = \frac{x}{y} \sqrt{ \frac{49}{49}- \frac{4}{49} }$

Simplify further:
$sin(t) = \sqrt{ \frac{45}{49} } = \frac{ \sqrt{45} }{7} = \frac{ \sqrt{9*5} }{7}$

And it all simplifies down to:
$sin(t) = \frac{3 \sqrt{5} }{7}$

Since it's in the 4th quadrant, the sin(t) value is going to be negative. So, your final answer is:
$sin(t) = - \frac{ 3\sqrt{5} }{7}$

Hope this helps!

Write 90 cm as a fraction of 2.4 m. Give your answer in its simplest form.

djverab [1.8K]

Answer:

$\frac{3}{80}$

Step-by-step explanation:

90 cm in metres is = 0.09 m

Writing it as a fraction of 2.4 m

=> $\frac{0.09 m}{2.4 m}$

<u><em>In simplest form</em></u>

=> $\frac{3}{80}$

You need to figure the mph for each person.

Maren drove 60 mph. No calculating needed there.

S drove 120/3 or 40 mph

T drove 84/1.2 mph or 70 mph

C drove 75/1/5 or 50 mph

The fastest was? (highest number is 70 as in Tomas)

Vesnalui [34]

First draw 24 shapes of your choice.

Then, in a different space or below those 24 shapes, draw 10 more shapes twice. So draw 10 shapes and draw 10 more next to them. Finally, draw 4 more shapes with space between them and say "10+10+4=24"
