Steps to solve:

\frac{4^-^3}{4^-^1}

~Use exponent rule [ \frac{x^a}{x^b}=x^a^-^b ]

4^-^3^-^(^-^1^)

~Simplify

4^-^2

~Use exponent rule [ a^-^b=\frac{1}{a^b} ]

\frac{1}{4^2}

~Simplify

\frac{1}{16}

None of the answer choices show the fully simplified version of the expression but one of the answers will be Option B.

To find the other correct answer, we can check each option.

Option A:

\frac{4^1}{4^3}

~Use exponent rule [ \frac{x^a}{x^b}=x^a^-^b ]

4^1^-^3

~Simplify

4^-^2

~Use exponent rule [ a^-^b=\frac{1}{a^b} ]

\frac{1}{4^2}

~Simplify

\frac{1}{16}

We need to go any further since we found the second correct answer.

Therefore, the answers are Option A and Option B

Best of Luck!

Simplify the following expression -5[(x^3+1)(x+4)]
katrin [286]

Answer:

B

Step-by-step explanation:

-5[ (x³+1)(x+4) ] = -5[ x³*(x+4) + 1*(x+4) ]

      = -5 [ x³*x + x³*4 + 1*x + 1*4 ]

      = -5 [ x⁴ + 4x³ + x + 4]

      = -5*x⁴ + (-5)*4x³ + (-5)*x + (-5) * 4

      = -5x⁴ - 20x³ - 5x - 20

Find the amount of interest owned for a $1,895 loan for 4 years at a 7.9% interest rate
scoundrel [369]

Answer:

principal (p)=$1895

time (t)=4years

rate(r)=7.9%

Step-by-step explanation:

  • compound interest amount=p((1+r/100)^t-1)=$1895((1+7.9/100)^4-1)=$1895×((1.355)-1)=$1895×(0.355)=$672.725
  • simple interest=ptr/100=$1895×4×7.9/100=$598.82

Find the value for the side marked below.
lions [1.4K]

Answer:

y = 189.8

Step-by-step explanation:

Apply trigonometric function to find y.

Reference angle (θ) = 50°

Adjacent side = 122

Hypotenuse = y

Apply CAH, since the Hypotenuse and the Adjacent are involved.

Thus:

Cos θ = Adj/Hypo

Plug in the values

Cos 50° = 122/y

y*Cos 50° = 122

y = 122/cos 50°

y = 189.8 (beater tenth)
