Put the following equation of a line into slope-intercept form, simplifying all fractions.

Alinara [238K]

Answer:

y=(x/2)+5

Step-by-step explanation:

Slope-intercept form is y=mx+b where m is the slope and b is the y-intercept form. To get that, we need y by itself so we have to add 3x to both sides: 6y=30+3x. Now we divide by 6 and rearrange the right side: y=(3x+30)/6.

y = (3x/6)+(30/6) => y = (x/2)+5. We also know that the slope is 1/2 and the y-intercept is 5 because of the slope-intercept equation.

In ΔRST, r = 210 inches, t = 550 inches and ∠T=166°. Find all possible values of ∠R, to the nearest degree.

valkas [14]

Answer:

m(∠R) = 5°

Step-by-step explanation:

By applying sine rule in the given triangle RST.

$\frac{\text{sin}(\angle R)}{ST}= \frac{\text{sin}(\angle T)}{SR}$

$\frac{\text{sin}(\angle R)}{r}= \frac{\text{sin}(\angle T)}{t}$

$\frac{\text{sin}(\angle R)}{210}= \frac{\text{sin}(166)}{550}$

sin(∠R) = $\frac{210\times \text{sin}(166)}{550}$

= 0.09237

m(∠R) = $\text{sin}^{-1}(0.09237)$

= 5.3°

≈ 5°

In a recent year, one United States dollar was equal to about 82 Japanese yen. How many Japanese yen are equal to $100? $1,000?

alexandr402 [8]

Well if $1=82 than $100 (which is 100 times 1) would equal 82·100=8,200
$1,000·82=82,000
$10,000·82=820,000 :) hope this helps!

A particle travels along the x-axis such that its velocity is given by v(t) = (t^0.7 + 4t) cos (t^2). What is the average accele

Airida [17]

It's not clear to me what the given interval is supposed to be, so I'll use a generic one, [a, b] with a < b.

The average acceleration of the particle over this interval is given by the average rate of change of v(t),

$a_{\rm ave} = \dfrac{v(b) - v(a)}{b - a} = \boxed{\dfrac{(b^{0.7}+4b)\cos(b^2) - (a^{0.7}+4a)\cos(a^2)}{b - a}}$
