7. stano. (2pt) Find the centers, foci, vertices and asymptotes of the hyperbola with equation given by: 16y²-x² - 6x - 32y = 57 And also sketch the hyperbola. (2pts)
The equation of parabola is a [tex]\frac{-(x+ 3)^{2}}{64} + \frac{ (y-1)^{2}}{4} = 1[/tex] and the coordinates of center is (0,0) And asymptote is become 16.
According to the statement
we have to find the centers, foci, vertices and asymptotes of the hyperbola from the given equations.
So, For this purpose,
Hyperbola is a a plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant.
So, The given equation is:
16y²-x² - 6x - 32y = 57
So, rearrange it then
-x² - 6x - 32y + 16y² = 57
-(x² + 6x) + (16y² - 32y ) = 57
-(x² + 6x) + 16(y² - 2y ) = 57
-(x² + 6x + 9) + 16(y² - 2y +1 ) = 57 +1(16) + 9(-1)
-(x+ 3)² + 16 (y-1)² = 64
-(x+ 3)² + 16 (y-1)² = 64
divide whole equation by 64 then
[tex]\frac{-(x+ 3)^{2}}{64} + \frac{16 (y-1)^{2}}{64} =\frac{64}{64}[/tex]
then equation become
[tex]\frac{-(x+ 3)^{2}}{64} + \frac{ (y-1)^{2}}{4} = 1[/tex]
This become the equation of hyperbola.
So,
here coordinates of center is (0,0)
And asymptote is become 16.
So, The equation of parabola is a [tex]\frac{-(x+ 3)^{2}}{64} + \frac{ (y-1)^{2}}{4} = 1[/tex] and the coordinates of center is (0,0) And asymptote is become 16.

A $8,000 principal is invested in two accounts, one earning 1% interest and another earning 6% interest. If the total interest for the year is $405, then how much is invested in each account?
The amount invested in the first account is $1,500 and $6,500 was invested in the second account.
What is simple interest?
Simple interest is determined as the principal multiplied by the interest rate ,then multiplied by the duration of the investment.
The formula for simple interest on an investment is as shown below:
I=PRT
P=principal=$8,000
R=interest rates= 1% and 6%
T=duration of investment=1 year
Let assume that X was invested at 1% and that the remaining of $8000-X is invested at 6%.
Interest on the first account=X*1%*1
Interest on the first account=0.01X

An envelope contains $1.20 in dimes and nickels. if the dimes were quarters and the nickels were dimes, there would be $1.35 more in the envelope. How many nickels are in the envelope?
The nickels in the envelope is $0. 12
How to determine the number
From the information given, we have that;
Dimes + nickels = $1. 20
1/4 dimes + dimes = $ 1. 35
Let dimes = d
Nickels = n
d + n = 1. 20 equation a

Consider a triangle ABC
like the one below. Suppose that a=75, b=63, and c=69.
The figure is not drawn to scale.) Solve the triangle.
round your answers to the nearest tenth.
If there is more than one solution, use the button labeled "or".
The given triangle has three angles with measurements: ∠A = 69°, ∠B = 52°, and ∠C = 59° respectively. Using the law of cosines, these angles are calculated from the given lengths of the triangle.
What is the law of cosines?The law of cosines gives the relationship between the lengths of sides and the angles of the triangle ABC.
According to the law of cosines:
Cos A = (b² + c² - a²)/2bc
Cos B = (a² + c² - b²)/2ac
Cos C = (a² + b² - c²)/2ab
Calculation:For the given triangle ABC,
a = 75, b = 63, and c = 69
So, using the law of cosines,
Cos A = (b² + c² - a²)/2bc
⇒ Cos A = (63² + 69² - 75²)/2×63×69
⇒ Cos A = 5/14
⇒ A = Cos⁻¹(5/14) = 69.07
∴ ∠A = 69°
Similarly,
Cos B = (a² + c² - b²)/2ac
⇒ Cos B = (75² + 69² - 63²)/2×75×69
⇒ Cos B = 31/50
⇒ B = Cos⁻¹(31/50) = 51.6 ≅ 52
∴ ∠B = 52°
Cos C = (a² + b² - c²)/2ab
⇒ Cos C = (75² + 63² - 69²)/2×75×63
⇒ Cos C = 179/350
⇒ C = Cos⁻¹(179/350) = 59.2
∴ C = 59°
Thus, the angles of the triangle ABC are 69°, 52°, and 59° respectively.

Using the monthly payment formula, it is found that:
Her monthly payments are of $105.46.The total finance charge is of $3,111.04.What is the monthly payment formula?It is given by:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
In which:
P is the initial amount.r is the interest rate.n is the number of payments.Considering that she must pay 20% down, the parameters are given by:
P = 0.8 x 2900 = 2320, r/12 = 0.085/12 = 0.007083, n = 24.
Hence the monthly payments are found as follows:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

Divide both sides by 23
[tex]x\approx 15.565[/tex]
So by looking at all these, it appears that 6x is the highest value, given that x is positive. The way I estimated, is approximately 15.5, whenever I saw an equation like x+14, I estimated it's about 2x, since 14 is not exactly, but close to 15.5. I did this with each polynomial given. You could also manually check each one
Original equation

What are two ordered pairs that the midpoint is (4, -10)? Please show that your points work.
The two ordered pairs that the mid point is (4,-10) are (4,-20),(4,0) & (4,0),(4,-20).
Given the coordinates of mid point be (4,-10).
We are required to find the ordered pairs that the mid point is (4,-20).
Coordinates show positions of points or something else on a surface.
There are various combinations whose mid point is (4,-10).
First are (4,-20),(4,0).
Mid point =[(4+4)/2,(-20+0)/2]
=(4,-10)
Second are (4,0) , (4,-20)
Mid point=[(4+4)/2,(0-20)/2]
=(4,-10)
Third are (8,-20),(0,0)
Mid point=[(8+0)/2,(-20+0)/2]
=(4,-10)
Fourth are (0,-20),(8,0)
Mid point =[(0+8)/2,(-10+0)/2]
=(4,-10)
Hence the ordered pairs that the mid point is (4,-10) are (4,-20),(4,0) & (4,0),(4,-20)& (8,-20),(0,0)&(0,-20),(8,0)&(0,0),(8,-20).etc.

What is the divisor the dividend is 5/9
Answer
5/9 is the dividend
Step-by-step explanation:
A particle is moving with the given data. Find the position of the particle. a(t) = t2 − 7t + 6, s(0) = 0, s(1) = 20
The function position of the particle is s(t) = (1 / 12) · t⁴ + (7 / 6) · t³ + 3 · t² + (63 / 4) · t.
What are the parametric equations for the motion of a particle?
By mechanical physics we know that the function velocity is the integral of function acceleration and the function position is the integral of function velocity. Hence, we need to integrate twice to obtain the function position of the particle:
Velocity
v(t) = ∫ t² dt - 7 ∫ t dt + 6 ∫ dt
v(t) = (1 / 3) · t³ - (7 / 2) · t² + 6 · t + C₁
Position
s(t) = (1 / 3) ∫ t³ dt - (7 / 2) ∫ t² dt + 6 ∫ t dt + C₁ ∫ dt
s(t) = (1 / 12) · t⁴ + (7 / 6) · t³ + 3 · t² + C₁ · t + C₂
Now we find the values of the integration constants by solving the following system of linear equations:
0 = C₂
63 / 4 = C₁ + C₂
The solution of the system is C₁ = 63 / 4 and C₂ = 0. The function position of the particle is s(t) = (1 / 12) · t⁴ + (7 / 6) · t³ + 3 · t² + (63 / 4) · t.

Another possible set of answers is:
-20, 10, -5,
I need the next sequence
Answer:
The next term in the sequence is 5/2 or 2.5.
========================
Given series:
-20, 10, - 5, ...We notice that this is a geometric progression.
The common ratio is:
r = -5/10 = 10/ -20 r = - 1/2To find the next term multiply the last term by the common ratio:
