The angle subtended by a diameter is always right.  That's Thales' Theorem, one of the first in geometry.  We conclude y=90°.

The angle subtended by an arc is half the arc length, so z=50°.

The angles in a triangle add to 180°, so x = 180° - y - z = 40°.

Answer: x=40°, y=90°, z=50°

HEEEEEEELLLPPPPPPPPP!!!!! PLEASEEEEEEEE
Klio2033 [76]

Answer:

a) a_n=2(a_{n-1}), where a_1=5.

b)  a_n=5(2)^{n-1}

Step-by-step explanation:

The given sequence is


5,10,20,40....


The first term of the sequence is

a_1=5


The second term is a_2=10


The common ratio for this sequence can be determined using any two consecutive terms in the sequence.

Using the first two terms, the common ratio is

r=\frac{a_2}{a_1}


\Rightarrow r=\frac{10}{5}=2


a) The recursive rule is given by,


a_n=r(a_{n-1})


a_n=2(a_{n-1}), where a_1=5.


b) The explicit rule is given by a_n=a_1r^{n-1}


\Rightarrow a_n=5(2)^{n-1}

Find the domain and range of the function y = f(x) = r2.=Domain:help (inequalities)Range:help (inequalities)
Juliette [100K]

we have the function

y=f(x)=x^2

the domain is all real numbers -------> interval (-∞, +∞)

the vertex of the vertical parabola is the origin (0,0)

the parabola opens upward

the vertex is a minimum

so

the range is the interval [0, ∞)
