The vertex<span> of a </span>parabola<span> is the point where the </span>parabola<span> crosses its axis of symmetry. If the coefficient of the x 2 term is positive, the </span>vertex<span> will be the lowest point on the graph, the point at the bottom of the “ U ”-shape.
</span><span>
The vertex of the parabola whose equation is y = x^2 + 8 x + 12 will be :
</span>(x , y) = (-4,-4)
First of all, we need all logarithms to have the same base. So, we use the formula
To change the second term as follows:
Finally, using the property
we have
So, the equation becomes
We can now use the formula
to write the equation as
Now consider both sides as exponents of 2:
This equation has no "nice" solution, so I guess the problem is as simplifies as it can be
Answer:
7 pounds
Step-by-step explanation:
8 divided by 4 is 2 so $2 per pound
14 divided by 2 is 7 so therefore it would be 7 pounds
I had the wrong answer before sry haha
Answer:
89·98 mph
Step-by-step explanation:
First, we get the circumference of the tires:
Circumference = × (radius × 2)
Circumference = 3.142 × (1·5 × 2)
Circumference = 3·142 × 3
Circumference = 9·426 ft
The circumference of the tire is equal to one round.
1 round = 9·426 ft
840 rounds = ?
We cross multiply to get the length that the tires would cover in a minute
= <u>840 × 9·426</u>
1
1 minute = 7917·84 ft
60 minutes = ?
<u>60 × 7917·84</u>
1
= 475070·4 ft
5280 feet = 1 mile
475070·4 feet = ?
<u>475070·4 × 1</u>
5280
475070·4 ÷ 5280 = speed of the car in mph
89·97545
Round this off to 2 decimal places...
= 89·98 mph
hope this helps! =)
