This equation is already in slope intercept form.

Slope intercept form is y = mx + b, which is the form it is in now. However, if you would like it changed to standard form, you would multiply by the lowest common denominator and then rearrange as follows.

y = -1/7x + 22/7 -----> Multiply both sides by 7

7y = -x + 22 ------> Add x to both sides

x + 7y = 22

write an exponential formula of the form f (t)= a×b^t to represent the following situation. assume t is in years. The beginning

nika2105 [10]

Answer:

$f(t)= 27000 * 0.965^t$

Step-by-step explanation:

Given

$a = 27000$ -- initial

$r = 3.5\%$

Required

The exponential equation

The exponential equation is

$y =ab^t$

Where

$b=1 -r$

We used minus, because the rate decreases..

So, we have:

$b=1 -3.5\%$

$b=1 -0.035$

$b=0.965$

So:

$y =ab^t$

$y = 27000 * 0.965^t$

Hence:

$f(t)= 27000 * 0.965^t$

A particle is moving along the curve y= 4sqrt(5x+11) . As the particle passes through the point (5,24) , its -coordinate increas

kupik [55]

The rate of change of the distance from the particle to the origin at this instant is 3 units per second.

<h3>What is the rate of change?</h3>

The instantaneous rate of change is the rate of change at a particular instant.

A particle is moving along the curve

$y= 4\sqrt{5x+11} .$

The rate of change of y is given as:

dy / dx = 2

by differentiating both sides,

$\dfrac{dy}{dx} = 4\dfrac{1}{2\sqrt{5x+11} } 5\dfrac{dx}{dt} \\\\\dfrac{dy}{dx} = \dfrac{10}{\sqrt{5x+11} }\dfrac{dx}{dt}\\\\$

From the question, we have:

(x, y) = (5,24)

Substitute 5 for x and dy / dx = 2

$\dfrac{dy}{dx} = \dfrac{10}{\sqrt{5x+11} }\dfrac{dx}{dt}\\\\\\5= \dfrac{10}{\sqrt{5(5)+11} }\dfrac{dx}{dt}\\\\\\\sqrt{5(5)+11} = 2\dfrac{dx}{dt}\\\\\\\dfrac{dx}{dt} = 6/ 2 = 3$

Hence, the rate of change of the distance from the particle to the origin at this instant is 3 units per second.

An 8 oz box of cocoa puffs costs $1.59 and a 2-pound box costs $6.79. which box is a better buy

VikaD [51]

Answer: 8 oz..

1 pound= 16oz if 8oz=1.59 so add it up 4 times 8+8+8+8= 32 which = 2 pounds total 8=1.59 8+8= 1.59x2=3.18 8+8+8=1.59x3=4.77 8+8+8+8/ 1.59x4= 6.36 so all of them eights will = up to 2 pounds and 8 is obviously less
