Answer:

A) 7

Step-by-step explanation:

Because the triangles are congruent to each other, then their corresponding angles are also congruent to each other. Thus, angles Z and V are congruent to each other:

$\angle Z=\angle V\\\\40^\circ=(5n+5)^\circ\\\\35=5n\\\\7=n$

Therefore, your answer is A.

4.
seems to be a geometric sequence
common ratio is -4
first erm is -2
$a_{n}=-2(-4)^{n-1}$

5. x=-1
remember x^-1=1/x
f(-1)=4(7^-1)=4(1/7)=4/7
f(2)=4(7^2)=4(49)=196

6. remember
(ab)/(cd)=(a/c)(b/d)
also
(x^m)/(x^n)=x^(m-n)
and
(x^m)(x^n)=x^(m+n)

so
$\frac{4.5*10^{3}}{9*10^{7}}$ =
( $\frac{4.5}{9}$ )( $\frac{10^{3}}{10^{7}}$ )=
(0.5)( $10^{3-7}$ =
(0.5)(10^-4)=
(5)(10^-1)(10^-4)=
(5)(10^(-1-4)
5*10^-5

4. $a_{n}=-2(-4)^{n-1}$

5. f(-1)=4/7
f(2)196

6. 5 times 10^-5

Find x. Problem is in the picture

Ratling [72]

Answer:

x = 80

Step-by-step explanation:

$22 \degree = \frac{1}{2} (x \degree - 36 \degree) \\ \therefore \: 22 \degree \times 2 = (x \degree - 36 \degree) \\ \therefore \: 44 \degree = x \degree - 36 \degree \\ \therefore \: 44 \degree + 36 \degree= x \degree \\ \therefore \: x \degree = 80 \degree \\ \: \: \: \: \: \huge \red{ \boxed{ \therefore \: x = 80 }}$
