Answer:

d=55t Sara travels 330 miles

Step-by-step explanation:

We are given that distance, d, Sarah drives varies directly to the time, t. This means

d=k⋅t

for some constant, k. Since Sarah travels 440 miles in 8 hours, we substitute these values into the formula for direct variation to find

440=k⋅8

Dividing by 8 gives k=55, so an equation that relates d and t is

d=55t

Substituting t=6 yields

55(6)=330

So Sarah can travel 330 miles in 6 hours.

440/8 will get you how many miles Sarah travel in 1 hour.

But Sarah travels 55 miles in 1 hour.

Sarah can travel 330 miles in 6 hour.

boeing plans to increase its price for jetliners. with a selling price $201.5 million and a cost of $190.1 million, what was the

scoray [572]

so from 190.1 to 201.5 is 201.5 - 190.1 = 11.4.

now, if we take 190.1 as the 100%, what is 11.4 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 190.1&100\\ 11.4&x \end{array}\implies \cfrac{190.1}{11.4}=\cfrac{100}{x}\implies 190.1x=1140 \\\\\\ x=\cfrac{1140}{190.1}\implies x\approx 5.99684$

Prove the following identity true. Show work.

yulyashka [42]

Answer:

The Pythagorean identity states that

$\sin^2 t + \cos^2 t = 1$

Using that we can rewrite the left denominator as:

$1 - \sin^2 t$

Which can be factored as

$(1 - \sin t)(1+ \sin t)$

The numerator we can expand as:

$(1 - \sin t)(1 - \sin t)$

On the right hand side, let's multply numerator and denominator with (1 - sin t):

The total formula then becomes:

$\dfrac{(1-\sin t)(1-\sin t)}{(1 - \sin t)(1 + \sin t)} = \dfrac{(1-\sin t)(1 - \sin t)}{(1+\sin t)(1 - \sin t)}$

There you go... left and right are equal.
