Step-by-step explanation:

In ΔIJK, the measure of ∠K=90°, IJ = 8.6 feet, and KI = 4.5 feet. Find the measure of ∠I to the nearest tenth of a degree.

Answers

Answer:

m∠I = 58.4°

Step-by-step explanation:

cos = adjacent side/hypotenuse

It is always helpful to have a picture.   In your case KI is adjacent to ∠I and IJ is the hypotenuse.

So cos I = KI/IJ = 4.5/8.6

     arccos (4.5/8.6) = m∠I

m∠I = 58.4°

It is necessary for you to memorize the definitions of the trig functions in order to do these types of problems.  OK?

Additive inverse of 400

Answers

Given:

A number is 400.

To find:

The additive inverse of 400.

Solution:

We know that the sum of a number and its additive inverse is 0.

If "a" is number and "b" is its additive inverse, then

[tex]a+b=0[/tex]

Let x be the additive inverse of 400. Then,

[tex]400+x=0[/tex]

Subtract both sides by 400.

[tex]400+x-400=0-400[/tex]

[tex]x=-400[/tex]

Therefore, the additive inverse of 400 is [tex]-400[/tex].

Security deposit is paid in advance to protect landlords against nonpayment.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

A security deposit is a sum of money paid by a tenant to a landlord or property manager before moving in, with the purpose of protecting the landlord in case the tenant does not fulfill their obligations under the lease agreement, such as not paying rent, damaging the property or leaving it unclean at the end of the lease.

The amount of the security deposit is usually equal to one or two months' rent, and it is refundable at the end of the lease term, provided that the tenant has complied with all the terms of the lease.

If the tenant has breached the lease agreement, the landlord may use the security deposit to cover the unpaid rent or any damages caused by the tenant.

Hence, Security deposit is paid in advance to protect landlords against nonpayment.

find the amplitude of the function. y=1.5sin4x

Answers

Answer:

amplitude is 1.5

Step-by-step explanation:

If amplitude of f(x) is a, the amplitude of f(cx + d) is also a, for any d and non-zero c.

If amplitude of f(x) is a, the amplitude of cf(x) + d is c*a, for any d and any c.

From that we know that amplitude of y=1.5sin4x is the same as amplitude of y=1.5sinx, and 1.5 times more than amplitude of y=sinx. And we know that amplitude of sinx is 1.

Thus, amplitude of y=1.5sin4x is 1.5

Answers

Answer:

Step-by-step explanation:

Not large

Total number of marbles = 4 + 7 + 6 = 17

Number of green marbles = 7

Probability of first marble being green =  7/17

Probability of the second marble being green = 6/16

Probability of the third marble being green = 5/15

Probability (3 green) = 7 / 17 * 6/16 * 5/15 = 210 / 4080 = 0.05147
