Answer: f(y) x g(y) = 1

Step-by-step explanation:

$\frac{2y^3-y^2+2y-1}{y^3-y^2+y-1}\cdot \frac{2y^2-3y+1}{4y^2-4y+1}\\\\= \frac{4y^5-8y^4+9y^3-9y^2+5y-1}{4y^5-8y^4+9y^3-9y^2+5y-1} \\\\= \frac{(y-1)(2y-1)(2y-1)(y^2+1)}{(y-1)(2y-1)(2y-1)(y^2+1)} \\\\= 1$

kodGreya [7K]

Answer:

$CI=189.5,194.5$

Step-by-step explanation:

From the question we are told that:

Sample size $n=40$

Mean $\=x =192$

Standard deviation $\sigma=8$

Significance Level $\alpha=0.05$

From table

Critical Value of $Z=1.96$

Generally the equation for momentum is mathematically given by

$CI =\=x \pm z_(a/2) \frac{\sigma}{\sqrt{n}}$

$CI =192 \pm 1.96 \frac{8}{\sqrt{40}}$

$CI=192 \pm 2.479$

$CI=189.5,194.5$

Help plz................

Pani-rosa [81]

You have the formula. Put in the numbers and solve for r.

The interest earned in 4 years on 5000 is (6500 -5000) = 1500.
.. I = Prt
.. 1500 = 5000*r*4
.. 1500/20000 = r = .075 = 7.5% . . . . . . matches selection B

Mike has $6000 to invest. He invested part of his total into an account earning 6% interest and the rest in an account earning 1

lesya692 [45]

Answer:$4000 was invested into the account earning 6% interest.

$2000 was invested into the account earning 11% interest.

Step-by-step explanation:

Let x represent the amount invested into the account earning 6% interest.

Let y represent the amount invested into the account earning 11% interest.

Mike has $6000 to invest. He invested part of his total into an account earning 6% interest and the rest in an account earning 11% interest. This means that

x + y = 6000

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

Considering the account earning 6% interest, the interest would be

I = (x × 6 × 1)/100 = 0.06x

Considering the account earning 11% interest, the interest would be

I = (x × 11 × 1)/100 = 0.11y

If at the end of the year, he earned $460.00 in interest, it means that

0.06x + 0.11y = 460 - - - - - - - - - - -1

Substituting x = 6000 - y into equation 1, it becomes

0.06(6000 - y) + 0.11y = 460

360 - 0.06y + 0.11y = 460

- 0.06y + 0.11y = 460 - 360

0.05y = 100

y = 100/0.05 = $2000

x = 6000 - y = 6000 - 2000

x = $4000
