If you can find one leg of a triangle to be congruent to a leg on the other triangle, then you can use the HL (hypotenuse leg) theorem. If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
Answer:
The velocity of the ball relative the racquet is 15 m/s.
Step-by-step explanation:
Given;
velocity of the tennis ball, = 30 m/s
Velocity of the racquet swung in opposite direction, = 15 m/s
The velocity of the ball relative the racquet () is calculated as;
Therefore, the velocity of the ball relative the racquet is 15 m/s.
Answer:
Correct answer:
3
Step-by-step explanation:
sing the defined function, f(a) will produce the same result when substituted for x:
f(a) = a2 – 5
Setting this equal to 4, you can solve for a:
a2 – 5 = 4
a2 = 9
a = –3 or 3
A number which is the result when one number is divided by another is known as quotient
