How to solve this equation for y. need assistance please. y-260=-11/5(x-100)

1 answer:

3 0

Y - 260 = 11/5 (x-100)

5y - 1300 = 11(x-100)
5y - 1300 = 11x - 1100

11x - 5y + 200 = 0
or
5y = 11x +200
y = $\frac{11}{5}x$ + 40

Elsa took out a $6000 loan for 5 months and was charged simple interest. The total interest she paid on the loan was $195. As a

vivado [14]

Answer:

the annual rate of interest is 7.8%

Step-by-step explanation:

The computation of the annual rate of interest is as follows:

As we know that

Simple interest = Principal × rate × time

$195 = $6,000 × rate × 5 months ÷ 12 months

$195 = 25 × rate

Rate = $195 ÷ 25

= 7.8%

Hence, the annual rate of interest is 7.8%

We simply applied the above formula so that the correct value could come

And, the same is to be considered

A person stands 10 meters east of an intersection and watches a car driving towards the intersection from the north at 13 meters

In-s [12.5K]

Answer:

Therefore the rate change of distance between the car and the person at the instant, the car is 24 m from the intersection is 12 m/s.

Step-by-step explanation:

Given that,

A person stand 10 meters east of an intersection and watches a car driving towards the intersection from the north at 13 m/s.

From Pythagorean Theorem,

(The distance between car and person)²= (The distance of the car from intersection)²+ (The distance of the person from intersection)²+

Assume that the distance of the car from the intersection and from the person be x and y at any time t respectively.

∴y²= x²+10²

$\Rightarrow y=\sqrt{x^2+100}$

Differentiating with respect to t

$\frac{dy}{dt}=\frac{1}{2\sqrt{x^2+100}}. 2x\frac{dx}{dt}$

$\Rightarrow \frac{dy}{dt}=\frac{x}{\sqrt{x^2+100}}. \frac{dx}{dt}$

Since the car driving towards the intersection at 13 m/s.

so, $\frac{dx}{dt}=-13$

$\therefore \frac{dy}{dt}=\frac{x}{\sqrt{x^2+100}}.(-13)$

Now

$\therefore \frac{dy}{dt}|_{x=24}=\frac{24}{\sqrt{24^2+100}}.(-13)$

$=\frac{24\times (-13)}{\sqrt{676}}$

$=\frac{24\times (-13)}{26}$

= -12 m/s

Negative sign denotes the distance between the car and the person decrease.

Therefore the rate change of distance between the car and the person at the instant, the car is 24 m from the intersection is 12 m/s.
