What is the slope of (-9,1) and (1,9)

Answer:

$875.18

Step-by-step explanation:

Given data

Lydia

P=$5900

Interest rate=2 5/8% >>21/8= 2.625%

compounded monthly.

First, convert R percent to r a decimal

r = R/100

r = 2.625%/100

r = 0.02625 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 5,900.00(1 + 0.0021875/12)^(12)(19)

A = $ 9,710.01

Jace

P=$5900

Interest rate= 2 1/8% >>> 17/8>> 2.125%

Time= 19 years

First, convert R percent to r a decimal

r = R/100

r = 2.125%/100

r = 0.02125 per year,

Then, solve our equation for A

A = Pert

A = 5,900.00(2.71828)^(0.02125)(19)

A = $ 8,834.83

Hence the difference in their account balance is

= 9,710.01- 8,834.83

=$875.18

Therefore Lydia has $875.18 more money than Jace

Answer:

Semimonthly is twice a month. There are 12 months in a year, which means Manny will get paid 12 x 2 = 24 times a year.

His annual salary is:

$1,239 x 24 = $29,736

Answer:

$43.4

Step-by-step explanation:

Let's say x is the cost per kilgram

30x = 93

x = 3.1

14x = 43.4

Answer:

1200

Step-by-step explanation:

i=prt

=80,000*0.02*9/12

=1200

Answer:

$a decreased by 25% and $1.2a decreased by 40%

$a decreased by 25% = 0.75a

1.2a decreased by 40% = 0.6*1.2a = 0.72a

2) $b increased by 250% and $2b increased by 50%

$b increased by 250% = 2.5b

$2b increased by 50% = 1.5*2b = 3b

Answer:

b increased by 250% is equal to 2b decreased by 50%

$b increased by 250% > $2b increased by 50%

Answer:

6.3

Step-by-step explanation:

Answer:

6.3 feet

Step-by-step explanation:

cosB= hypotenuse/adjacent = x/6.4

​cos8 = x/6.4

6.4 cos8= x

x= 6.3377 = 6.3 feet

Hi! From what I know, your answer should be 5n = 1.75.

This is because all 5 of those n's ultimately equal the large box of 1.75 on the top. Think of it as fractions. if we replaced 1.75 with 1, those n's would each be 1/5.

Step-by-step explanation:

The doubling period of a bacterial population is 15 minutes.

At time t = 90 minutes, the bacterial population was 50000.

Round your answers to at least 1 decimal place.

:

We can use the formula:

A = Ao*2^(t/d); where:

A = amt after t time

Ao = initial amt (t=0)

t = time period in question

d = doubling time of substance

In our problem

d = 15 min

t = 90 min

A = 50000

What was the initial population at time t = 0

Ao * 2^(90/15) = 50000

Ao * 2^6 = 50000

We know 2^6 = 64

64(Ao) = 50000

Ao = 50000/64

Ao = 781.25 is the initial population

:

Find the size of the bacterial population after 4 hours

Change 4 hr to 240 min

A = 781.25 * 2^(240/15

A = 781.25 * 2^16

A= 781.25 * 65536

A = 51,199,218.75 after 4 hrs

Answer:

Negative

Step-by-step explanation:

Years of Factoring:

What the problem tells us is that we have:

X^2 - 4x - 3

or something along these lines. If we factor this we get:

(X-4)(X+1)

The bigger inside factor has to be negative for these problems, because the third term is negative.

The sum of the middle term must give a negative value.

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that If the middle term of a quadratic trinomial is negative and the last term is negative then the sum of the middle terms must give a negative value.

What the problem tells us is that we have:

x² - 4x - 3

Something along these lines. If we factor this we get:

(x-4)(x+1)

The bigger inside factor has to be negative for these problems because the third term is negative.

Therefore, the sum of the middle term must give a negative value.

After finding the speed of both objects, we found that 264km travelled in 2 hours is the fastest of both.

What is meant by the speed of an object?

A thing's speed is the rate at which it covers a distance in a given amount of time. The object that moves quickly covers a greater distance in less time. On the other hand, items that move slowly cover a relatively small distance in a given period of time. As speed simply has no direction and only magnitude, it is a scalar quantity. The instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance travelled by the object divided by the duration of the period.

We are asked to find the speed of two different objects.

Object 1

Distance travelled = 264km

Time taken = 2 hours

Speed = distance/time = 264/2 = 132km/h

Object 2

Distance travelled = 585km

Time taken = 5 hours

Speed = distance/time = 585/5 = 117 km/h

From the above two speeds, we can see that object 1 travels 132km in one hour while object 2 only travels 117km in one hour.

Therefore after finding the speed of both objects, we found that 264km travelled in 2 hours is the fastest of both.

a=1/2 base times height

a=(1/2)(6)(4)

a=12 ft

Now find the area of the circles:

a= pi times radius squared

a= pi times 2.5 squared

a=19.63 ft

19.63 + 12 = 31.63 ft

Janice's age is 35 years.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Ross age = x

Now,

Janice age = 5x ____(1)

Janice age = x + 28 _____(2)

From (1) and (2),

5x = x + 28

5x - x = 28

4x = 28

x = 7

Now,

Janice age.

= 5 x 7

= 35

Thus,

Janice's age is 35 years.

$30.00 + $1.80 = $31.80

Answer:

$31.8

Step-by-step explanation:

here's your solution

=> Cost of video game = $30

=> sale tax = 6%

=>now we need to calculate 6% of $30

=> 6/100*30 = $1.8

=> sale tax = $1.8
