Step-by-step explanation:
4x×8y
and x =2 and y=4
pit the values of x and y in above equation we get
4(2)×8(4)
now multiply
8×32
256
Answer:
The speed of the object at time, t=4 is 
Step-by-step explanation:
The speed is calculated using the formula;

The distance covered by the object is given in terms of t, as

At time t=4, the distance covered by the object is;


The speed can now be calculated by substituting t=4 and distance 80 meters to obtain;

Answer:
6 feet
Step-by-step explanation:
Gonna use the Pythagorean Theorem: a² + b² = c²
a² + 8² = 10²
a² + 64 = 100
Subtract both sides by 64
a² + 64 = 100
-64 -64
a² = 36
Square root both sides
√a² = √36
a = 6 = length between bottom of the wall to the base of the ladder
Answer:
Step-by-step explanation:
2y/y + 2 + 4/y+2
2y/2y + 4/2y
1y + 2y
