How many solutions does this linear system have Y =- 6x 2 and 12x 2y =- 4 Brainly?.

The two possible functions is F(x)= \frac{x^4}{12}+3x^2 and F(x)= \frac{x^4}{12}+3x^2+x.

The derivative of the first derivative of the given function is known as the second order derivative. We can learn about the slope of the tangent at a particular position or the instantaneous rate of change of a function at that point from the first-order derivative at that point.

F”(x)= x^2+6

F’(x)= \int f"(x) dx

       = \int( x^2+6) dx

       = \frac{x^3}{3}+6x+c_1                                  c_1 is the integral constant.

F(x)= \int f\prime(x) dx

      = \int f (\frac{x^3}{3}+6x+c_1) dx

      = \frac{x^4}{12}+3x^2+c_1x+c_2

(i) if c_1=0 , and c_2=0

   F(x)= \frac{x^4}{12}+3x^2

(ii) if c_1=1, and c_2=0

        F(x)= \frac{x^4}{12}+3x^2+x

Therefore the two possible functions is F(x)= \frac{x^4}{12}+3x^2 and F(x)= \frac{x^4}{12}+3x^2+x

The probability that one of the scores in the sample is less than 1585 is 4.9%

Given that,

Given that mean u = 1585

standard deviation σ = 80

sample size n = 33

Probability means is the ability to happen. The subject of this area of mathematics is the occurrence of random events.The value is expressed in the range of 0 to 1. Probability has been brought to mathematics to predict the likelihood of events. Probability is essentially defined as the degree to which something is likely to occur.

P(x<1585) = P(X-u/σ < 1585-1595/80)

                 = P (X-u/σ  < -0.125)

P(x<1585) = 0.45026

P(x>1585) = 1 - P(x<1585) = 0.54974

P(1585<x<1595) = 0.5 - P(x<1585) = 0.049738

So, The probability that one of the scores in the sample is less than 1585 is 4.9%

The deferred tax liability given the following items incurred in 2020 by company b. Bonuses are tax deductible only in the year in which they are paid, is 372.

In the give question, we have to calculate the deferred tax liability given the following items incurred in 2020 by company b.

Bonuses are tax deductible only in the year in which they are paid.

From the given question;

Accounting Income                   = 86000

Add Depreciation expence       = 6500

Less Tax Depreciation              = 4000

Less 2019 Bonus Paid in 2020 = 2630

Add 2020 accured Bonus         = 3500

Total Taxable Income                = 84670

Accounting income is more that the taxable income. Hence defffered tax liability will arise on the temporary taxable difference.

Temporary Taxable Difference = 86000-84670 = 1330

So Deffered Tax Liability = 1330*28% = 372

Abigali should invest $14197.97 in this amount to get the goal

From the formula of the simple interest,

S.I = P.r.t/100

Simple interest is the interest amount on the particular amount for the required rate in a given interval of time.

Where S.I = simple interest for the original amount

P = principal amount

t = number of times of period

r =rate interest

In this problem, we have

r = 6.92

S.I = 5896

t = 6 years

Since, Abigali pays 6.92% simple interest per year in her account for the interest of $5896 in the six years

Therefore, as per the question

P = (S.I x 100)/r.t

The solution to this system of linear equations y - x = 6, y + x = - 10 is (-8, -2).

What is system of linear equations?

The set of two or more linear equations containing the same variables is known as a system of linear equations in mathematics. In this case, linear equations are first-order equations, where the maximum power of the variable is 1. One, two, or three variables may be present in a linear equation.

Given that;

Y - x = 6

Y + x = -10

Let's equalize the two equations as they are both equal to y;

x + 6 = - x - 10

By further calculation

x + x = - 10 - 6

2x = - 16

Divide both sides by 2

x = -8

The value of x should be replaced in either equation;

y - x = 6

y - (-8) = 6

So we get

y + 8 = 6

y = 6 - 8

y = - 2

Therefore, the solution to this system of linear equations y - x = 6, y + x = - 10 is (-8, -2).

After t = 60.3 minutes will the temperature of the object be equal to 80 degrees.

The function  f(t) = Ce^-kt + 77........ (1)  

Now, at t = 0, f(0) = 150 = C + 77

C = 73

So, the function (1) becomes  f(t) = 73e^-kt + 77 ......... (2)

Now, it is given that at t = 10 minutes, f(10) = 120 degree.

Consequently, from equation (2),  120 = 73e^-kt + 77

73e^-10k = 43

e^-10k = 0.589

Now, taking logarithm ln  both sides we get -10k (ln e) =ln (0.589)

k = 0.0529

Therefore, the equation (2) becomes  f(t) = 73e^-( 0.0529)t + 77  ......(3)

Now, putting f(t) = 80 degree, we have from equation (3),

f(t) = 73e^-( 0.589)t + 77

80 = 73e^-( 0.589)t + 77

e^-( 0.0529)t = 0.041

Taking ln both sides we get, -0.0529t = - 3.19, ⇒ t = 60.3 minutes

The object's temperature will reach 80 degrees after t = 60.3 minutes.
