Answer:

163800"

Step-by-step explanation:

1°=60'

1' =60"

so,

45°30'

=(45°×60×60)"+(30×60)"

=162000"+1800"

=163800"

So,45°30' is equal to 163800".

Solve the equations. a. 4a^2 = 16 b. 5????^2 − 25 = 0 c. 8 − c^2 = 5

Vera_Pavlovna [14]

Answer:

$a=\pm 2$ , $x=\pm \sqrt{5}$ and $c=\pm \sqrt{3}$ .

Step-by-step explanation:

Consider the given equations are

a. $4a^2=16$

b. $5x^2-25=0$

c. $8-c^2=5$

(a)

$4a^2=16$

Divide both sides by 4.

$a^2=4$

Taking square root on both sides.

$a=\pm \sqrt{4}$

$a=\pm 2$

(b)

$5x^2-25=0$

Add 25 on both sides.

$5x^2=25$

Divide both sides by 5.

$x^2=5$

Taking square root on both sides.

$x=\pm \sqrt{5}$

(c)

$8-c^2=5$

Subtract 8 from both sides.

$-c^2=-3$

Multiply both sides by -1.

$c^2=3$

Taking square root on both sides.

$c=\pm \sqrt{3}$

Let g(x) = x2 + x. Find g(-10). A) -100 B) -90 C) 0 D) 90

laila [671]

Put -10 where x is and do the arithmetic.

g(x) = x² + x

g(-10) = (-10)² + (-10) = 100 - 10 = 90 . . . . . . corresponds to selection D

_____

If you like, you can factor the expression to make evaluation easier.

g(x) = x(x +1)

g(-10) = (-10)(-9) = 90
