While riding her bike, Susan burns 450 calories every ½ hour. Based on this

Mathematics

Answer:

1575 calories

Step-by-step explanation:

Every \frac{1}{2} an hour while riding her bike, Susan burns 450 calories.  

If the rate remains constant then within one hour riding her bike Susan will burn ( 450 × 2 ) = 900 calories.  

Now, it is asked to calculate the number of calories that Susan burns in 1\dfrac{3}{4} hours bike riding.

Here, 1\dfrac{3}{4} = \dfrac{7}{4} hours

Therefore, in \dfrac{7}{4} hours she will burn \dfrac{900\times 7}{4} = 1575 calories. (Answer)

I need help with Algebra 2. Thank you! :)
andre [41]

Answer:

B: 6.0

Step-by-step explanation:

-3t^2+9t+54 = 0

This is the equation that needs to be solved

Divide both sides by -3

t^2 - 3t - 18 = 0

The factors of 18 are: (1 18) (2 9) (3 6)

3 - 6 = -3 and 3 x -6 = -18

So: (t + 3) (t - 6) = 0

t = -3, 6

It can't be negative so the answer is 6

What is the axis of symmetry for f(x) = −3x2 + 12x − 6?
Marta_Voda [28]
The axis of symmetry can be found by finding the average of the zeros, a derivation from the conservation of energy :P, or by finding the point when the velocity is equal to zero.

df/dx=-6x+12 so df/dx, velocity, equals zero when:

-6x+12=0

6x=12

x=2  so the axis of symmetry is the vertical line x=2

....

average of zeros...

3x^2-12x+6=0

x^2-4x+2=0

x^2-4x=-2

x^2-4x+4=2

(x-2)^2=2

x-2=±√2

x=2±√2  so the average of the zeros is obviously 2.

....

conservation of energy

vf-vi=at  When vf=0, this is the maximum value for f(x)...

-vi=at, vi=b and a(acceleration)=2a(from quadratic) and t=x

-b=2ax

x=-b/(2a)  in this case

x=-12/(2(-3))

x=-12/-6

x=2

Solve the system of equations by substitution.
sineoko [7]
Answer is A. -2x + 3z
Reason
2x + y = 3z
If you subtract 2x from both sides to isolate “y”
2x -2x +y = -2x + 3z
Now combine like terms
You get
y= -2x + 3z
