(1 point) An innovative rural public health program is reducing infant mortality in a certain West African country. Pretend the

nataly862011 [7]

Answer:

Infant mortality will reduce to 33% in 1.63 years

Step-by-step explanation:

Let the population be X

Population after 1 year

$X - 7.3$ % of $X$

$X -0.073 X\\0.927X$

As we know

$P = P_0 * e^{rt}$

Substituting the given values we get -

$\frac{P_0 - 0.33P_0}{P_0} = e^{-0.33 * t}\\0.67 = e^{-0.33 * t}\\$

Taking log on both sides we get -

$-0.20273 = -0.33 * t\\t = 1.627$

Quadratic Functions Put the equationy = x^2 + 14a + 40 into the form y = (x - h )^2 + k: Answer: y Preview Get help: Video Poins

Artist 52 [7]

Answer:

The required form is $y=(x+7)^2-9$ .

Step-by-step explanation:

Consider the provided quadratic function.

$y=x^2 + 14x + 40$

We need to put the equation into the form $y = (x - h )^2 + k$

Add and subtract 49 in order to make the above function a perfect square.

$y=x^2 + 14x+49-49 + 40$

$y=x^2 + 14x+7^2-49 + 40$

$y=(x+7)^2-49 + 40$

$y=(x+7)^2-9$

Hence, the required form is $y=(x+7)^2-9$ .

I could really use your help

nydimaria [60]

Answer:

x = $\frac{c-a}{5y}$

Step-by-step explanation:

Given

5xy + a = c ( isolate 5xy by subtracting a from both sides )

5xy = c - a ( isolate x by dividing both sides by 5y )

x = $\frac{c-a}{5y}$
