L=R*angle, but the angle *must* be in radians. So, just translate 43 degrees into radians: 43 * pi / 180, and you'll get:
L = 42 * ( 43 * pi / 180 ) ~ 31.504666, which rounded to the nearest hundredth is 31.50 cm.
Answer:
y = -3/4x - 2
Step-by-step explanation:
y = -3/4x + b
1 = (-3/4) × -4 + b
1 = 3 + b
-2 = b
b = -2
y = -3/4x -2
Answer:
30.25
Step-by-step explanation:
All angles of a line must add up to 180. Since we already know that one angle is 90 degrees, we know that the other angles should add up to 90 degrees in order for all of the angles to add up to 180 degrees:
(3x-7)+(x+8)=90
4x+1=90
4x=89
x=22.25
22.25+8= 30.25
Answer:
4 
km
Step-by-step explanation:
To find how much farther Hallie biked after lunch compared to the amount she biked before lunch, we can subtract the amounts:
6 
However, we can only subtract fractions that have the same denominator, so we need to convert 
to a fraction with a denominator of 8:
Now, we can't subtract 2 from 8, so we need to 'borrow' from the 6 to make the fraction larger:
Now subtract: 
Graph A is a linear function, while Graph B is an exponential funtion.
