Answer:
true
Step-by-step explanation:
sinA² + cosA²=1
⇔(1/2)² + cosA²=1
⇔cosA=±(√3/2)
Slope-intercept form is y = mx + b
The slope can be found by dividing y(2) - y(1) by x(2) - x(1).
4 - 3 = 1
2 - 0 = 2
m = 1/2
Since the first point has an x-coordinate of 0, the y-coordinate is the y-intercept of the line.
b = 3
Equation: y = 1/2x + 3
Answer:
#1 is d
#2 is A

Step-by-step explanation:
Answer:
first day = 5.05mm = 0.505cm
second day = 9.55mm = 0.955cm
Step-by-step explanation:
Let x represent first day
Let y represent second day
x + y = 14.6
x = y - 4.5
(y - 4.5) + y = 14.6
2y - 4.5 = 14.6
2y = 14.6 + 4.5
2y = 19.1
Divide both sides by coefficient of y which is 2
y = 9.55
Substituting value of y in the equation x + y = 14.6
x + 9.55 = 14.6
x = 14.6 - 9.55
x = 5.05
To convert the values in mm to cm you divide them by 10 since 1cm=10mm
Step-by-step explanation:
The formula to find the final velocity, v of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
(a) v=u+at
Subtract u from both sides,
v-u=u+at-u
v-u=at
Dividing both sides by t.
(b) The relationship between the acceleration and time for a given initial and final velocity is given by "
Where
s is the distance covered
t is the time
Hence, this is the required solution.
