Faelyn noticed that she does not have a common factor. Which accurately describes what Faelyn should do next?

2 answers:

4 0

Without knowing what Faelyn has done so far or what she is working with, the second selection seems appropriate.

6x^4 -5x^2 -4
= (6x^4 +3x^2) -(8x^2 +4)
= 3x^2*(2x^2 +1) -4(2x^2 +1)
= (3x^2 -4)(2x^2 +1)

Answer:

$(3x^2-4)(2x^2+1)$

Step-by-step explanation:

Given that Faelyn noticed that she does not have a common factor.

The polynomial is

$6x^4-5x^2-4$

She can multiply constant term and leading term.

6*-4 =-24

The factors are -8 and 3 which when added give the middle coefficient -5.

Hence this can be factored by grouping as

$(6x^4+3x^2)-(8x^2+4)\\= 3x^2(2x^2+1)-4(2x^2+1)\\=(3x^2-4)(2x^2+1)$

In a right triangle, the acute angles measure x + 15 and 2x degrees.

Valentin [98]

Answer:

50°

Step-by-step explanation:

x+15+2x=90

3x=90-15=75

x=75/3=25

one acute angle=25+15=40°

other acute angle=2×25=50°

The function in Exercise represents the rate of flow of money in dollars per year. Assume a 10-year period at 8% compounded cont

Kryger [21]

Answer:

a) $P= $56,972.5$

b) $A=$1,26,792.3$

Step-by-step explanation:

Given Data:

Interest rate= $r= 0.08$ per year

No. of years= $t=10$

Rate of continuous money flow is given by the function

$f(t)=2000$

a) to find the present value of money

$P=\int\limits^n_0 {f(t)e^{-rt} } \, dt$

Put f(t)=2000 and n=10 years and r=0.08

$P=\int\limits^n_0 {2000e^{-0.08t} } \, dt$

Now integrate

$P= {2000(\frac{e^{-0.08t}}{-0.08} )$

$P= -\frac{2000}{0.08} (e^{-0.08*10}-e^{-0.08*0})$

$P= -\frac{2000}{0.08} (e^{-0.8}-e^{0})$

$P= -\frac{2000}{0.08} (0.4493-2.7282)$

$P= -\frac{2000}{0.08} (-2.2789)$

$P= -25000(-2.2789)$

$P= $56972.5$

(b) to find the accumulated amount of money at t=10

$A=P(e^{rt} )$

Where P is the present worth already calculated in part a

$A=56972.5(e^{0.08*10} )$

$A=56972.5(e^{0.8} )$

$A=56972.5(2.2255 )$

$A=$1,26,792.3$

PLEASE HELP!!<br> Write Y=x^2+4x+3 in standard form

DanielleElmas [232]

Answer:

already in standard form

Step-by-step explanation:

the equation of a quadratic in standard form is

y = ax² + bx + c ( a ≠ 0 )

y = x² + 4x + 3 ← is in standard form

with a = 1 , b = 4 , c = 3
