Answer:
x=25 or x=0
Step-by-step explanation:
4x(x−25)=0
Step 1: Simplify both sides of the equation.
4x2−100x=0
For this equation: a=4, b=-100, c=0
4x2+−100x+0=0
Step 2: Use quadratic formula with a=4, b=-100, c=0.
x=−b±√b2−4ac over 2a
x=−(−100)±√(−100)2−4(4)(0) over 2(4)
x=100±√10000 over 8
x=25 or x=0
Answer:
1.07328
Step-by-step explanation:
223.6 x 0.0048=1.07328
A dilation pushes all points outwards, a factor of 2 would double the distance (in this case the point V)
every further step is then also an increase of the factor so
1->U (nothing changes)
2->V
3->W
4->X
so the correct answer is 4
Answer:
3.3 miles per hour. this is because speed is equal to distance travelled divided by time taken. so you calculate how many minutes he spent that is from 9:15 to 10:00 . since you are calculating in miles per hour, you convert the minutes to hours and do the working according to the formula
