I think that the answer is 1.25

Answer:

L = 5/4 yards

L = 1 1/4 yards

L = 1.25 yards

Step-by-step explanation:

area = Length * Width

3/4 = L * 3/5

Divide both sides by 3/5

(3/4) / (3/5) = L

When dividing by a fraction flip it over and multiply

3/4 * 5/3 = L

The 3 cancels

5/4 = L

L = 5/4 yards

as a proper fraction

L = 1 1/4 yards

As a decimal

L = 1.25 yards

Suppose you are running a racing tournament with 12 horses. All eligible horses run in the race at once, and after the first rac
borishaifa [10]

Answer:

a)  66

b)  45

Step-by-step explanation:

We have 12 horses and after the first race 2 of them have to be eliminated

that condition is equal to consider that 10 horses will be available for the second race.

The number of possiblities we have for the first race is the combination of 12 horses in group of 10

C¹²₁₀   =  12!/ (2!)* (12-2)!   =  12*11/2   = 66

For the second race

C¹⁰₈  = 10! / 8! * (10-8)!   =   10*9/ 2   = 45

Simplify the expression 1/√(1-cos^2 x) . Remember cos x= 1/csc x
Cerrena [4.2K]
First, we are going to use the Pythagorean identity: sin^2(x)+cos^2(x)=1 to rewrite our expression. Solving for sin^2(x) in our Pythagorean identity  we get that sin^2(x)=1-cos^2(x), so we can rewrite our expression as follows:
\frac{1}{ \sqrt{1-cos^2(x)} } = \frac{1}{ \sqrt{sin^2(x)} } = \frac{1}{sin(x)}

Next, we are going to use the trig identity: csc(x)= \frac{1}{sin(x)} to completely simplify our expression:
\frac{1}{sin(x)} =csc(x)

We can conclude that \frac{1}{ \sqrt{1-cos^2(x)} }=csc(x)

Suppose that $3000 is placed in an account that pays 16% interest compounded each year. Assume that no withdrawals are made from
Papessa [141]

Answer:

a) $3480

b) $4036.8

Step-by-step explanation:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Suppose that $3000 is placed in an account that pays 16% interest compounded each year.

This means, respectively, that P = 3000, r = 0.16, n = 1

So

A(t) = P(1 + \frac{r}{n})^{nt}

A(t) = 3000(1 + \frac{0.16}{1})^{t}

A(t) = 3000(1.16)^{t}

(a) Find the amount in the account at the end of 1 year.

This is A(1).

A(t) = 3000(1.16)^{t}

A(1) = 3000(1.16)^{1} = 3480

(b) Find the amount in the account at the end of 2 years.

This is A(2).

A(2) = 3000(1.16)^{2} = 4036.8
