As the angles are complementary sin A = cos B and  sin B = cos A

so sin A + sin B =  0.55 + 0.83 =  1.38

Answer:

sin(A)+sin(B)=1.38

Step-by-step explanation:

Let

A, B and 90\° the measures of the angles in a right triangle

we know that

m ------> by complementary angles

so

sin(A)=cos(B)

sin(B)=cos(A)

In this problem we have

cos(A)=0.83

cos(B)=0.55

therefore

sin(A)=0.55

sin(B)=0.83

sin(A)+sin(B)=0.55+0.83=1.38

Y_Kistochka [10]

Answer:

The set of numbers of the form \frac{p}{q} , q≠0 and q≠ 1 or -1.

Step-by-step explanation:

We have that,

U = the universal set = the set of all rational numbers

S = set of all integers.

It is required to find S^{c}.

Now, S^{c} is the complement of the set S.

i.e. S^{c} = U - S = set if rational numbers - set of integers

i.e. S^{c} = the set of rationals which are not integers i.e. the set of points of the form \frac{p}{q} , q≠0 and q≠ 1 or -1.

What is the present value of a $50,000 decreasing perpetuity beginning in one year if the discount rate is 7% and the payments d
Trava [24]

Answer:

Present Value = $1666666.67

Step-by-step explanation:

Present Value of a Growing Perpuity is calculated using the following formula

PV =D/(r - g)

Where D = Dividend

r = Discount Rate

g = Growth rate

D = $50,000

r = 7%

r = 7/100

r = 0.07

g = 4%

g = 4/100

g = 0.04

PV = D/(r-g)

Becomes

PV = $50,000/(0.07-0.04)

PV = $50,000/0.03

PV = $1,666,666.67

So the Present Value of the perpuity is $1,666,666.67

Justin receives $15 and puts it into his savings account. He adds $0.25 to the account each day for a number of days, d, after t
MAVERICK [17]

Answer:

expression a

Step-by-step explanation:

The given expression is 15+0.25(d−1).

let suppose,

15 = a

0.25(d−1) = b

we get  a + b

It clearly indicates the given expression is sum of two entities, we can exclude  option b and option d.

Now we are left with option a and c, for that we have to evaluate the term b

b = 0.25(d−1) <u>that is the additional amount after d days</u>

Therefore, expression a is correct.
