You want $5000 4 years from nowfor a down payment for a car. How much money must be deposited monetly into an account earning 4.2% compounded monthly to achieve this goal?
Answer:
$95.5090 must be deposited monthly
Step-by-step explanation:
From the information given:
The annual interest rate (r) = 4.2% = 0.042
Let assume that an amount Y is deposited, then after one month, it will increase to:
[tex]Y ( 1+ \dfrac{0.042}{12})[/tex]
The total amount after 4 years will be:
[tex]= Y ( 1+ \dfrac{0.042}{12})^{48}+Y ( 1+ \dfrac{0.042}{12})^{47} +Y ( 1+ \dfrac{0.042}{12})^{46} +...+ Y ( 1+ \dfrac{0.042}{12})[/tex]
[tex]= Y ( 1.0035)^{48}+Y ( 1.0035)^{47} +Y( 1.0035)^{46} +...+ Y( 1.0035)[/tex]
Using the sum of a geometric progression:
[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{(1.0035-1)}[/tex]
[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{0.0035}[/tex]
The above amount is then equal to $5000
i.e
[tex]= Y (1.0035) \dfrac{ (1.0035^{48}-1)}{0.0035} = 5000[/tex]
[tex]Y = \dfrac{5000\times 0.0035}{(1.0035)(1.0035^{48}-1)} \\ \\ \mathbf{Y = \$95.5090}[/tex]

CAN SOMEONE PLEASE GELP ME?
Answer:
1 ) 140
2) 60
Step-by-step explanation:
1. It touches the y intercept at 140 and 0 in the x axis so 140
NOTE : THE NUMBER THE TOUCHES THE Y INTERCCEPT IS ALWAYS THE ANSWER/ IT GOES DOWN 3 ACROSS 3 SO IT AND U WILL SEE IF IT TOUCHES THE Y INTERCEPT IT WILL BE 140
2. it goes from 140 to 200 just subtract them to get how much she gets

are there?
Answer:
12 green marbles
Step-by-step explanation:
first we know that there are 39 red and blue marbles, so 3x+10x=39 x=3
since the amount of green marbles is 4x, and we know x=3, x*4=12

find x and y
Answer:
The "middle triangle"
50+85+n=180
n+135=180
n=45
The "left side triangle"
x+68+45=180
x=67
The "right-side triangle"
50+74+z=180
124+z=180
z=56
y=180-56
y=124
Let me know if this helps!
i need help plz huryyy
Answer:
x=128
Step-by-step explanation:
180-52=128
Answer: x= 128 degrees
Step-by-step explanation:
Angle “x” and angle with measure of 52 degrees are a linear pair.
Linear pairs sum to 180.
52+x=180. Subtract 52 from both sides.
X= 128
*OR you can use angles around a point sum to 360 degrees.
52+38+142+x = 360. Combine like terms.
232+x= 360. Subtract 232 from both sides.
X= 128

What is the equation of the line perpendicular to y = 1/4x – 5 through the point (4,3)?
y-yi=m(x-xi)
y-3=1/4(x-4)
y-3=x-4/4
4y-12=x-4
4y+x-12+4=0
4y+x-8=0
so the equation of
the line perpendicular
to
y=1/4-5 through
the point(4,3)
is4y-x-8=0
One-third of a number plus 2 is greater than 11. What are the possible values for ?
Answer:
The equation is 1/3x+2>11
Anything greater than 27 is a possible answer
Step-by-step explanation:
Step 1
Subtract 2 from both sides, 2-2 cancels out and 11-2=9
Now you have 1/3x>9
Step 2
Divide both sides by 1/3, 1/3 divided by 1/3 cancels outs and 9 divided by 1/3 is 27
Now you have x>27
So anything greater than 27 is a possible answer

Prove \triangle ABE\cong\triangle ACE△ABE≅△ACE. Be sure to state any congruencies and the criteria used to determine them.
Answer:
The answer is below
Step-by-step explanation:
Two triangles are congruent if they have the same shape and their corresponding sides are equal to each other.
1) AB = DC, BE = CE (given)
2) ∠AEB≅∠DEC (vertical angles are congruent)
3) ΔABE ≅ ΔACE (side angle side congruence theorem)
If the two sides and an included angle of one triangle is equal to two sides and one included angle of another triangle, then the two triangles are congruent by SAS congruence theorem.
