Help with these twoo

Answers

Answer 1

Answer:

g(N)=3 + 7n

80 = 3 + 7n

move the variable to the left hand side so

80 - 7n = 3

now do 3 - 80 to get -7n = -77

now divide both sides by -7 to get

n=11

2nd

p(x) = 4x

6= 4x

so swap the equations so its

4x = 6

next divide both sides by 4

x = 3/2 or 1.5

Patrick wants to buy a new computer. He already has $275 saved and plans to save $125 each month. The price of the computer is currently $1,850, but Patrick expects the price to drop by $100 each month. Patrick wants to determine the number of months he will need to save.

a) If x represents the number of months, then write an equation to represent A, the total amount Patrick saves.

b)If x represents the number of months, then write an equation to represent C, the cost of the computer.

c)Use your equations from part “a” and part “b” to determine how many months he will need to save before he can buy the computer. Show your work or explain how you got your answer.

Answers

Answer:

7 months

Step-by-step explanation:

A(x) = 275 + 125x

C(x) = 1850 - 100x

275 + 125x = 1850 - 100x125x + 100x = 1850 - 275225x = 1575x = 1575 / 225x = 7

The answer is 7 months

The mean weight of a domestic house cat is 8.9 pounds with a standard deviation of 1.1 pounds. The distribution of domestic house cat weights can reasonably be approximated by a normal distribution. What proportion of domestic house cats weigh less than 7 pounds?

Answers

Answer:

0.0421

Step-by-step explanation:

We solve using the z score formula

z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean = μ = 8.9 pounds

σ is the population standard deviation = σ = 1.1 pounds

For x < 7 pounds

z = 7 - 8.9/1.1

= -1.72727

Probability value from Z-Table:

P(x<7) = 0.042059

Therefore, the proportion of domestic house cats weigh less than 7 pounds is

0.042059

Approximately = 0.0421

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB=20 and AD=10, what is the length of AC?

Answers

Answer:

mAC = 40

Step-by-step explanation:

Use similar triangles,

BAC and DAB are similar

therefore

CA/AB = BA/AD

CA/20 = 20/10

cross multiply

AC = CA = 20*20/10 = 40

Or use metric relations

CA*AD = BA^2

CA = BA^2/AD = 20^2/10 = 40

Start by using the distance formula to find the raidus

The two points are (-2,1) and (-4,1)

√((-4+2)²+(1-1)²)= 2

The radius is two and we have our center which means we can write

(x+2)²+(y-1)²=4

now it's just a matter of expanding everyhting

x²+4x+4+y²-2y-3=0

x²+y²+4x-2y+1=0

Answer:

73,205 vinyls

Step-by-step explanation:

To calculate the number of vinyls sold we need to calculate the compounded increase. To do this we simply raise the number of times that the initial value increases by the number of difference in years from the start to the current year. Then we multiply this number by the initial number of vinyl records. Since there are 4 years between 2012 and 2016, the formula would be the following...

50,000 * [tex]1.1^{4}[/tex] = x

50,000 * 1.4641 = x

73,205 = x

Finally, we can see that there will be a total of 73,205 vinyls in 2016

Round your answer to one decimal digit. The volume of a cylinder is 1 800 cm3. If the height of the cylinder is 40 cm then the diameter of the cylinder is

Answers

Answer:

7.57 cm

Step-by-step explanation:

Volume of a cylinder = πr²h

π = 3.14

r= radius

h = height

1,800 = 3.14 x r² x 40

r² = 1800 /(3.14 x 40)

r² = 14.33121

√14.33121 = r

r = 3.785658 cm

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

Diameter = 2 x 3.785658 cm = 7.57cm
