n a right triangle, the tangent of angle A is 912 and the cosine of angle A is 1215. Based on these values, what is the sine of
Allisa [31]

Answer:

Option A sin(A)=\frac{9}{15}

Step-by-step explanation:

we know that

tan(A)=sin(A)/cos(A)

Solve for sin(A)

sin(A)=tan(A)cos(A)

we have

tan(A)=\frac{9}{12}

cos(A)=\frac{12}{15}

substitute

sin(A)=\frac{9}{12}(\frac{12}{15})

sin(A)=\frac{9}{15}

According to the Fundamental Theorem of Algebra, which polynomial function has exactly 8 roots?
natta225 [31]

Answer:

Polynomials of degree 8 have exactly 8 roots

Step-by-step explanation:

The Fundamental Theorem of Algebra states that every polynomial of degree n

P(x)=a_0+a_1x+a_2x^2+...+a_nx^n

with

a_n\neq 0

has exactly n roots.

But the roots may be complex numbers.

In your case n=8, so polynomials of degree 8 have exactly 8 roots.

The roots need not be different.

For example, for the polynomial

x^2-4x+4

x=2 is root twice.

Last question of the day with 25 points.
pshichka [43]

Answer:

244 degrees

Step-by-step explanation:

Since one angle APE is 90 degrees, that means line segments AD and BE are perpendicular bisectors.

Since both segments go through the center, that means all the angles are central angles.

Since angle APE is 90 degrees, that also means that angle EPD is 90 degrees.

33k -9 = 90

33k = 99

k = 3

Since we know k we can substitute it to find angle CPD.

20 k + 4 = 20*3 + 4= 60+4= 64 degrees.

Central angles equal angles of arcs, so we can and angles APE, EPD, and DPC to find the measure of major arc CAD.

64+ 90 +90 = 244 degrees
