Answer:
Step-by-step explanation:
P=(2,-3)
Q=(a,a²-2a-3)

Proof:
y'=(x²-2x-3)'=2x-2
y'(2)=2*2-2=2
Answer:
30/40, 75/100, 9/12, 15/20, 24/32
Step-by-step explanation:
all you have to do is multiply the numerator and the denominator by the same number. for example, 3*5 = 15 and 4*5 = 20 so you get 15/20.
Answer:
Two acute angles
Step-by-step explanation:
The right triangle has one 90 degree angle and two acute angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.
120/12=x
120/12=10
Then answer to this problem is B
1) 90/257 * 100
900/257
= 35.0%
It means, 90 is 35% of 257.
Hope this helps! Do all the others in same manner!!
2) 12/24 * 100 = 1200/24 = 50%
3) 25/208 * 100 = 2500/208 = 12.01%
4) 60/188 * 100 = 6000/188 = 31.91%
5) 24/44 * 100 = 2400/44 = 54.54%
Hope this helps!
