Answer:
angle 2 = 90° {corresponding angles}
angle 7 + angle 5 = 180° {linear pair}
or, angle 7 + 100° = 180° {angle 5 is corresponding to 100°}
so, angle 7 = 80°
The acceleration is given by the slope of the line. This line passes through the points (0, 2) and (3, 5), so it has slope

which means the acceleration over this 3 second interval is 1 m/s^2.
Answer:
On a coordinate plane, a curve starts in quadrant 3 and then increases into quadrant 1. It crosses the y-axis at (0, negative 2) and crosses the x-axis at (1.5, 0)
Step-by-step explanation:
The attached graph is an example of the square root function scaled and translated.
_____
No transformation of the square root curve will turn it into a parabola or into two curves.
Answer:
A
Step-by-step explanation:
No others make sense because you can't use multiplication in this problem and well it's hard to explain honestly lol. But I'm almost certain your answer is A
Answer:
Exact value of Cos(45° - 60°) is 0.96 using difference of two angles.
Step-by-step explanation:
Given:
Cos(45° - 60°)
We have to apply the formula of cosine for difference of the two angles.
Formula:

Plugging the values.
⇒ 
We know that the values :
and 
So,
⇒ 
⇒ 
⇒ 
⇒
...<em>rationalizing </em>
⇒ 
⇒
...<em>taking 2 as a common factor</em>
<em>⇒ </em>
To find the exact values we have to put the values of sq-rt .
As<em>, </em>
and 
Then
<em>⇒ </em>
<em />
<em>⇒ </em>
<em />
⇒ 
So the exact value of Cos(45° - 60°) is 0.96 using difference of two angles.
