A business purchases a computer system for $5,300. The value of the system decreases at a rate of 12% per year. In how many year
N76 [4]

Answer:

7

Step-by-step explanation:

If a system decreases by 12% it's the same as multiplying it by .12-1 or .88

This means we can create the following equation

computer value=5300(.88)^n

where n is the number of years

We can then plug in the value of the computer and solve for n

2200=5300(.88)^n

Divide by 5300 and get

.415=.88^n

Then put this into log form and get

\frac{log(.415)}{log.88}

Evaluate this into your calculator and get n=6.69 which I would probably just round to 7

The employees of a company were surveyed on questions regarding their educational background (college degree or no college degre
taurus [48]

Answer: D) 0.733.

Step-by-step explanation:

Let C denotes the number of employees having college degree and S denote the number of employees are single.

We are given ,

Total = 600 , n(C)=400  , n(S)=100 , n(C∩S)=60

Then,

n(C\cup S)=n(C)+n(S)-n(C\cap S)\\\\=400+100-60=440

Now, the probability that an employee of the company is single or has a college degree is

P(C\cup S)=\dfrac{n(C\cup S)}{\text{Total}}\\\\=\dfrac{440}{600}=0.733333333\approx0.733

Hence, the probability that an employee of the company is single or has a college degree is 0.733

ABC and ACD are both right angled triangles. a) explain why the length of AC is 13cm.​
timofeeve [1]

Answer:

In the picture attached, the question is shown.

a) Applying Pythagorean theorem to triangle ABC, and solving for AC:

CB² + BA² = AC²

5² + 12² = AC²

√169 = AC

13 cm = AC

b) Applying Pythagorean theorem to triangle ACD, and solving for AD:

CD² + AC² = AD²

5² + 13² = AD²

√194 = AD

13.9 cm = AD

A circle is centered at the point (5, -4) and passes through the point (-3, 2).
Dafna11 [192]
The equation of a circle with center (h, k) and radius r is
.. (x -h)^2 +(y -k)^2 = r^2
Filling in the given information, you have
.. (-3-5)^2 +(2-(-4))^2 = r^2
.. 64 +36 = r^2 = 100

The equation of the circle is then
.. (x -5)^2 +(y +4)^2 =100

Your blanks are filled with (-5), (4), (100).
