Answer:
-94
Step-by-step explanation:
f(-7): YOU MUST SUB THIS INTO THE CORRECT EQUATION. DO NOT SUB -7 INTO G!!! SUB IT INTO F
-2x(-7)^2 + 4
-2x(49) + 4
-98 + 4
= -94
The answer is 23 because 5 x 4 +3 is 23
Answer:
Step-by-step explanation:
14x - 49 - 3 + 3x = 9 - 6 + 9x
17x - 52 = 9x + 3
8x - 52 = 3
8x = 55
x = 55/8
Answer:
Therefore other two sides of the triangle are 4 and 5.
Step-by-step explanation:
Given one leg of a right triangle has a length of 3
Let other sides of the triangle be x and x+1 [ since they are consecutive]
According to the problem,
3²+x²=(x+1)²
⇔9 + x²=x²+2x+1
⇔2x+1=9
⇔2x=9-1
⇔2x=8
⇔x=4
Therefore other two sides of the triangle are 4 and 5.
Answer:
Step-by-step explanation:
Given that,
Initial speed of a vehicle, u = 25 km/hr = 6.95 m/s
Final speed of a vehicle, v = 1200 km/hr = 333.34 m/s
Time, t = 60 s
We need to find the acceleration of the vehicle. It is equal to the rate of change of velocity. It can be given by :
So, the acceleration of the vehicle is .
