Step-by-step explanation:

It is like a elevator. You have to walk to the elevator to go before you can go up. So you go to the negative area first and then climb up because 8 is positive, and that would land you in Quadrent II

Answer:

30 years and a half

Step-by-step explanation:

well let's just say 3.5k x hmm 2? at an estimate and that will get us to 7000.. so in order to get to 7000 we have to wait 15 years which is 30 years and a half. From Xthermyx. A brainly user.

It would take 22.7 years for the value of the account to reach $7,700.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Since the money in the account is doubling every 15 years.

The following equation is used to find the time it takes to reach a certain value:

t = (ln(P/F))/(ln(1+r))

where:

P = the initial investment amount

F = the future value we want to reach

r = the growth rate per period

ln = natural logarithm

t = the number of years it takes to reach F

P = $3,500

F = $7,700

r = ln(2)/15 (since the money is doubling every 15 years).

Plugging these values into the equation.

t = (ln(3500/7700)) / (ln(1+ln(2)/15))

t = ln (5/11) / ln (1 + 0.30/15)

t = 22.7

Therefore,

It would take 22.7 years for the value of the account to reach $7,700.

Answer:

Distance between points m and p = 12.53 unit (Approx.)

Step-by-step explanation:

Given:

Co-ordinate of points

m(-10, 3)

p(-4, -8)

Find:

Distance between points m and p

Computation:

Distance between two points = √(x1 - x2)² + (y1 - y2)²

Distance between points m and p = √(-10 + 4)² + (3 + 8)²

Distance between points m and p = √(-6)² + (11)²

Distance between points m and p = √36 + 121

Distance between points m and p = √157

Distance between points m and p = 12.53 unit (Approx.)

Answer:

FV= $70,887.15

Step-by-step explanation:

First, we need to calculate the future value of the $130 deposit for 5 years:

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit= $130

i= 0.08/12= 0.0067

n= 5*12= 60 months

FV= {130*[(1.0067^60) - 1]} / 0.0067

FV= $9,561.96

Now, using the following formula, the future value of the investment after 25 years:

FV= PV*(1 + i)^n

n= 25*12= 300

FV= 9,561.96*(1.0067^300)

FV= $70,887.15

Answer:

1. 53

2. 20

3. 37

4. 29

Step-by-step explanation:

Since your trying to find the hypotenuse you equation is...

1. 28^2 + 45^2 = C^2

    784 + 2025 = C^2

      Square Root 2809= C^2

    C=53

So after you square root 2809 you get 53.

2. 12^2 + 16^2 = C^2

     144 + 256 = C^2

      Square Root 400 = C^2

    C=20

So after you square root 400 you get 40.

3.  12^2 + 35^2 = C^2

    144 + 1225 = C^2

    Square Root 1369 = C^2

   C=37

So after you square root 1359 you get 37.

4. 20^2 + 21^2 = C^2

   400 + 441 = C^2

  Square root 841 = C^2

  C=20

So after you square root 841 you get 29.

Answer:

Acceleration is 0.5 m/s² and the distance covered is 6.25 m.

Step-by-step explanation:

Given that,

Initial speed, u = 0

Final speed, v = 9 km/h = 2.5 m/s

Time, t = 5 seconds

We need to find the acceleration and the displacement covered in that time. Acceleration = rate of change of velocity

So,

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{2.5-0}{5}\\\\a=0.5\ m/s^2[/tex]

Distance d can be calculated using third equation of motion.

[tex]d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{2.5^2-0^2}{2\times 0.5}\\\\d=6.25\ m[/tex]

So, acceleration is 0.5 m/s² and the distance covered is 6.25 m.

Answer:

42. x = 25

43. LM = 11

Step-by-step explanation:

For 42, the three angles of a triangle, when added, = 180 degrees. We know that one of the angles is 90 degrees...a right angle.

So: 90 + 2x + x + 15 = 180

105 + 3x = 180

3x = 75

x = 25

If they ask for more information: the three angles are 90 degrees, 50 degrees (2x), and 40 (x + 15). 90 + 50 + 40 = 180

For 43, ray PN bisects (cuts in equal halves) the triangle. We know this because the two segments LP and PM are equal. As a result, the triangles LPM and PNM are mirror images. Since MN = 11, LM also = 11.
