how much money must be deposited now in an account paying 3.5% annual interest, compounded monthly, to have a balance of 20,000 after 15 years?(show work please)
Approximately $10,758.90 must be deposited now in the account to have a balance of $20,000 after 15 years, assuming a 3.5% annual interest rate compounded monthly.
To calculate the amount of money that must be deposited now to have a balance of $20,000 after 15 years, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = final balance ($20,000)
P = principal amount (initial deposit we want to find)
r = annual interest rate (3.5% or 0.035 as a decimal)
n = number of times interest is compounded per year (monthly, so n = 12)
t = number of years (15)
Substituting the given values into the formula:
$20,000 = P(1 + 0.035/12)^(12*15)
Next, we can simplify the equation and solve for P:
$20,000 = P(1 + 0.0029166666666667)^(180)
$20,000 = P(1.0029166666666667)^(180)
To isolate P, we divide both sides of the equation by (1.0029166666666667)^(180):
P = $20,000 / (1.0029166666666667)^(180)
P ≈ $10,758.90
Therefore, approximately $10,758.90 must be deposited now in the account to have a balance of $20,000 after 15 years, assuming a 3.5% annual interest rate compounded monthly.

(X2-X1) (-2)-(1)= -3 ΔX -3
slope= 4
B= -3
Y =4X -3
Answer:
y=4x-3
Step-by-step explanation:
Hi there!
We are given the points (1,1) and (-2, -11) and we want to write the equation of the line in slop-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
So let's find the slope of the line
The formula for the slope calculated from two points is \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1, y_1)\) and \((x_2, y_2)\) are points
We have everything we need to calculate the slope, let's just label the points to avoid confusion
\(x_1=1\\y_1=1\\x_2=-2\\y_2=-11\)
Now substitute those values into the formula
m=\(\frac{y_2-y_1}{x_2-x_1}\)
m=\(\frac{-11-1}{-2-1}\)
Subtract
m=\(\frac{-12}{-3}\)
Divide
m=4
So the slope of the line is 4
Here is the equation of the line so far:
y=4x+b
We need to find b
As the equation passes through both (1,1) and (-2, -11), we can plug either one of them into the equation to solve for b
Taking (1,1) will give us this:
1=4(1)+b
Multiply
1=4+b
Subtract 4 from both sides
-3=b
Substitute -3 as b into the equation
y=4x-3

Albinism in humans is autosomal and fully recessive to normal color. A couple, who are both normal, have a daughter who is albino and a son who is normal. The couple wants to have 3 more children. What is the probability that they will have 3 normal girls?
The probability that the couple will have 3 normal girls is approximately 0.422
Since both parents are normal, they both have to be heterozygous carriers for the recessive allele that causes albinism. We can represent the normal allele with the letter N and the albino allele with the letter n. Then, we can write the genotypes of the parents as Nn x Nn.
The daughter is albino, so her genotype must be nn. The son is normal, so his genotype must be Nn.
We want to find the probability that the couple will have 3 normal girls. We can use the multiplication rule of probability to find this probability:
P(3 normal girls) = P(normal girl) x P(normal girl) x P(normal girl)
The probability of having a normal girl is 3/4 since there are three possible genotypes that result in a normal phenotype (NN, Nn, Nn) out of a total of four possible genotypes. The probability of having a normal boy is also 3/4, for the same reason.
Therefore, the probability of having 3 normal children (in this case, girls) is:
P(3 normal girls) = (3/4) x (3/4) x (3/4) = 27/64 ≈ 0.422
So, the probability that the couple will have 3 normal girls is approximately 0.422, or about 42.2%.

let a = (a1, a2) and b = (b1, b2) and c = (c1,c2) be three non zero vectors. if a1b2 - a2b1 is not equal to 0. then show three are two scalars, α and ß, such that c = αa + ßb.
Consider the contrapositive of the statement you want to prove.
The contrapositive of the logical statement
p ⇒ q
is
¬q ⇒ ¬p
In this case, the contrapositive claims that
"If there are no scalars α and β such that c = αa + βb, then a₁b₂ - a₂b₁ = 0."
The first equation is captured by a system of linear equations,
\(\begin{cases}c_1 = \alpha a_1 + \beta b_1\\ c_2 = \alpha a_2 + \beta b_2\end{cases}\)
or in matrix form,
\(\begin{pmatrix}c_1\\c_2\end{pmatrix} = \begin{pmatrix}a_1&b_1\\a_2&b_2\end{pmatrix}\begin{pmatrix}\alpha\\\beta\end{pmatrix}\)
If this system has no solution, then the coefficient matrix on the right side must be singular and its determinant would be
\(\begin{vmatrix}a_1&b_1\\a_2&b_2\end{vmatrix} = a_1b_2-a_2b_1 = 0\)
and this is what we wanted to prove. QED
Which graph shows function f?
The graph of f(x) is the second one, so the correct option is B.
Which graph shows function f?Here we have f(x), a piecewise function, and we want to see which one of the four graphs is the correct one.
You can see that the first domain of the function is:
x ≤ -4
So we must have a closed circle at x = -4, when the parabola ends.
The second domain is:
-4 < x < 1
So x here is not equal to -4 nor 1, so this part starts and ends with open circles.
finally, the linear part starts with a closed circle.
Also, notice that the line has a negative slope, so it goes down, then we can discard the first option.
Then we can see that the correct option is the second graph.

. Write the equation of a line with a slope of 4 passing through the point (3, 1). Write the
equation in slope-intercept form.
Answer:
y = 4x - 11
Step-by-step explanation:
The general equation of the slope-intercept form of a line is given by:
y = mx + b, where
(x, y) are any point on the line,m is the slope,and b is the y-intercept.We can find b, the y-intercept of the line, by plugging in 4 for m and (3, 1) for (x, y) in the slope-intercept form:
1 = 4(3) + b
1 = 12 + b
-11 = b
Thus, the y-intercept is -11.
Thus, the equation of the line with a slope of 4 passing through the point (3, 1) in slope-intercept form is y = 4x - 11
The answer is:
y = 4x - 11Work/explanation:
First, we will write the equation in point slope:
\(\sf{y-y_1=m(x-x_1)}\)
where m = slope;
(x₁,y₁) is a point on the line.
Plug in the data:
\(\sf{y-1=4(x-3)}\)
Simplify
\(\sf{y-1=4x-12}\)
Add 1 on each side
\(\sf{y=4x-12+1}\)
\(\sf{y=4x-11}\)
Hence, the equation is y = 4x - 11.A truck was purchased for $188000 and it was estimated to have a $32000 salvage value at the end of its useful life.

11. Write the equation for the graph
This is the same as writing y = sqrt(4(x+5)) - 1
===============================================
Explanation:
The given graph appears to be a square root function.
The marked points on the curve are:
(-4,1)(-1,3)(4,5)Reflect those points over the line y = x. This will have us swap the x and y coordinates.
(-4,1) becomes (1,-4)(-1,3) becomes (3,-1)(4,5) becomes (5,4)Recall the process of reflecting over y = x means we're looking at the inverse. The inverse of a square root function is a quadratic.
----------
Let's find the quadratic curve that passes through (1,-4), (3,-1) and (5,4).
Plug the coordinates of each point into the template y = ax^2+bx+c.
For instance, plug in x = 1 and y = -4 to get...
y = ax^2+bx+c
-4 = a*1^2+b*1+c
-4 = a+b+c
Do the same for (3,-1) and you should get the equation -1 = 9a+3b+c
Repeat for (5,4) and you should get 4 = 25a+5b+c
We have this system of equations
-4 = a+b+c-1 = 9a+3b+c4 = 25a+5b+cUse substitution, elimination, or a matrix to solve that system. I'll skip steps, but you should get (a,b,c) = (1/4, 1/2, -19/4) as the solution to that system.
In other words
a = 1/4, b = 1/2, c = -19/4
We go from y = ax^2+bx+c to y = (1/4)x^2+(1/2)x-19/4
----------
Next we complete the square
y = (1/4)x^2+(1/2)x-19/4
y = (1/4)( x^2+2x )-19/4
y = (1/4)( x^2+2x+0 )-19/4
y = (1/4)( x^2+2x+1-1 )-19/4
y = (1/4)( (x^2+2x+1)-1 )-19/4
y = (1/4)( (x+1)^2-1 )-19/4
y = (1/4)(x+1)^2- 1/4 - 19/4
y = (1/4)(x+1)^2 + (-1-19)/4
y = (1/4)(x+1)^2 - 20/4
y = (1/4)(x+1)^2 - 5
The equation is in vertex form with (-1,-5) as the vertex. It's the lowest point on this parabola. Placing it into vertex form allows us to find the inverse fairly quickly.
----------
The last batch of steps is to find the inverse.
Swap x and y. Then solve for y.
y = (1/4)(x+1)^2 - 5
x = (1/4)(y+1)^2 - 5
x+5 = (1/4)(y+1)^2
(1/4)(y+1)^2 = x+5
(y+1)^2 = 4(x+5)
y+1 = sqrt(4(x+5))
y = sqrt(4(x+5)) - 1
I'll let the student check each point to confirm they are on the curve y = sqrt(4(x+5)) - 1.
You can also use a tool like GeoGebra to verify the answer.
