Answer:

Step-by-step explanation:

(1.2 x 10-4) + (2.4 x 10-3)

Simplify

1.2 x 10- 4 = 8

2.4 x 10- 3 = 21

Add both sums to get 29!

SCIENTIFIC NOTATION

2.9 x 10 to the 1st power

Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better

Method 1 :

replace x and y by their value 1 and 3

3 = 4(1) - 1 = 4-1 = 3

2(1) + 3 = 2 + 3 = 5

correct

Method 2 :

y = 4x - 1

2x + y = 5

y = 4x - 1

y = -2x + 5

y - y = 4x - 1 - ( -2x + 5 )

0 = 4x - 1 + 2x - 5

6x - 6 = 0

6x = 6

x = 6/6 = 1

y = 4x - 1

y = 4(1) - 1

y = 3

correct

Given the angles inscribed in the circle, find m ∠ DBC.

Cloud [144]

Answer:

m∠DBC = 51°

Step-by-step explanation:

Circle Theorem vocabulary

Chord: A straight line joining two points on the circle.
Inscribed angle: The angle formed when two chords meet at one point on a circle.
Intercepted arc: The arc that is between the endpoints of the chords that form the inscribed angle.

Inscribed Angle Theorem

The measure of an inscribed angle is half the measure of the intercepted arc.

Therefore:

$\sf \implies \angle DBC=\dfrac{1}{2}\:\overset{\frown}{BC}$

$\sf \implies \angle DBC=\dfrac{1}{2}\:(102^{\circ})$

$\sf \implies \angle DBC=51^{\circ}$
