ATTENTION ATTENTION, BURNING QUESTION!!

Recall the slope intercept form of an equation is:

y = mx + c, where m is the slope and c = vertical intercept.

y + 2 = 5x + 4

y + 2 = 5x + 4

y = 5x + 4 - 2

y = 5x + 2

So the slope intercept form is y = 5x + 2

Hope this helps.

According to data from a medical association, the rate of change in the number of hospital outpatient visits, in millions, in

GaryK [48]

Answer:

a) $f(t)=0.001155[\frac{2}{3}t(t-1980)^{3/2}-\frac{4}{15}(t-1980)^{5/2}]+264,034,000$

b) f(t=2015) = 264,034,317.7

Step-by-step explanation:

The rate of change in the number of hospital outpatient visits, in millions, is given by:

$f'(t)=0.001155t(t-1980)^{0.5}$

a) To find the function f(t) you integrate f(t):

$\int \frac{df(t)}{dt}dt=f(t)=\int [0.001155t(t-1980)^{0.5}]dt$

To solve the integral you use:

$\int udv=uv-\int vdu\\\\u=t\\\\du=dt\\\\dv=(t-1980)^{1/2}dt\\\\v=\frac{2}{3}(t-1980)^{3/2}$

Next, you replace in the integral:

$\int t(t-1980)^{1/2}=t(\frac{2}{3}(t-1980)^{3/2})- \frac{2}{3}\int(t-1980)^{3/2}dt\\\\= \frac{2}{3}t(t-1980)^{3/2}-\frac{4}{15}(t-1980)^{5/2}+C$

Then, the function f(t) is:

$f(t)=0.001155[\frac{2}{3}t(t-1980)^{3/2}-\frac{4}{15}(t-1980)^{5/2}]+C'$

The value of C' is deduced by the information of the exercise. For t=0 there were 264,034,000 outpatient visits.

Hence C' = 264,034,000

The function is:

$f(t)=0.001155[\frac{2}{3}t(t-1980)^{3/2}-\frac{4}{15}(t-1980)^{5/2}]+264,034,000$

b) For t = 2015 you have:

$f(t=2015)=0.001155[\frac{2}{3}(2015)(2015-1980)^{1/2}-\frac{4}{15}(2015-1980)^{5/2}]+264,034,000\\\\f(t=2015)=264,034,317.7$

Find the y-intercept of 2x - 3y = 6

Ksju [112]

Answer:

(0, - 2)

Step-by-step explanation:

The y-intercept is the value of y when x = 0. Substitute 0 for x in the equation and solve for y.

$2x - 3y = 6$

$2(0) - 3y = 6$

$- 3y = 6$

$\frac{ - 3y}{ - 3} = \frac{6}{ - 3}$

$y = - 2$

When x = 0, y = - 2.

Volume and formula question!

-Dominant- [34]

Answer:

h = 2√3

Step-by-step explanation:

Using pythagorean's theorem:

a² + b² = c² such that

h² + 2² = 4²

h² = 16 - 4

h² = 12

h= √12

h = √ 4 * 3

h = 2 √3

Note:

I divided the base and made it 2.

The other slant side = 4
