Answer:

Option B. 0.9272

Step-by-step explanation:

In the given triangle ABC, ∠CAD = 22° segment CB = 15 cm.

We have to find sin of ∠C.

In the given triangle ADC,

∠CAD + ∠ADC + ∠DCA = 180

22° + 90° + ∠DCA = 180

∠DCA = 180 - 112 = 68°

Now we have to get the value of sinC or sin of angle DCA

Therefore sinC = sin 68° = 0.9272

Option B. 0.9272 is the correct option.

Marrrta [24]

Answer:

total cost of her loan be if she paid it off 8 years early $389,507.11

Step-by-step explanation:

The formula for annual compound interest, including principal sum P, rate of interest r, number of years t, and  the number of times that interest  is compounded per year is n:

A = P (1 + r/n)^ (nt)

calculate total cost after 22 years

P = $145,000

r = 4.5 %

t = 22 years

n = 12

A = P (1 + r/n)^ (nt)

A =  145,000(1 + 4.5/12)^ (22x12)

A = $389,507.11

Whats a significant figure
Alenkasestr [34]

Answer:

Significant figures are any digits that contribute to the number: In 02.400, only 2 and 4 are significant digits.  However, in 2.4001, 2, 4, 0, 0, and 1 are significant digits, because the number would not be the same without them.

Step-by-step explanation:

Let f and g be functions. (a) The function (f + g)(x) is defined for all values of x that are in the domain(s) of ____________.
krok68 [10]

Answer:

a) for all values of x that are in the domains of f and g.

b) for all values of x that are in the domains of f and g.

c) for all values of x that are in the domains of f and g with g(x)≠0

Step-by-step explanation:

a) By definition (f+g)(x)=f(x)+g(x). Then x must be in the domain of f and g.

b) By definition (fg)(x)=f(x)g(x).  Then x must be in the domain of f and g.

c) By definition (f/g)(x)=f(x)/g(x).  Then x must be in the domain of f and g and g(x) must be different of 0.

Solve: k/5+3-3k=-6k
tia_tia [17]

\frac{k}{5} +3-3k=-6k

Multiply both sides of the equation by 5

k+15-15k=-30k

Move the expression to the right side and change the sign

k=-15-30k+15k

Combine Like terms

k=-15-15k

So I think the final answer would be k=-15-15k
