If 125% of a number is 425, what is 65% of the number?
Can anyone explain this one?

Answers

Answer 1

Answer: $125\%\ \ \rightarrow\ \ 425\n\n65\%\ \ \rightarrow\ \ x\n \n125\cdot x=65\cdot425\ /:125\n\nx= (65\cdot425)/(125) \n\nx=(5\cdot13\cdot25\cdot17)/(5\cdot25)\n\nx=13\cdot17\n\nx=221$

Which graph shows the quadratic function y = 3x^2 + 12x + 10?

Answers

Answer with explanation:

→The quadratic function is

y = 3 x² + 12 x + 10

$y=3(x^2+4 x+(10)/(3))\n\ny=3[(x+2)^2-4+(10)/(3)]\n\ny=3[(x+2)^2-(2)/(3)]\n\ny+2=3(x+2)^2$

→Vertex of the parabola=(-2,-2),in third Quadrant.

→Drawing the Parabola,which will open upwards ,that is along positive y axis.

→ Line, x= -2 , is the line of symmetry of Quadratic function.

As,the function is Quadratic, it has either two real root or two imaginary.

But, it has two real root, which are , x=-2.816,-1.184, because,

Find the center of the circle that can be circumscribed about ABC with A(0,0) B(6,0) C(6,4)

Answers

This can be solved by the distance formula.
If the center of the circle is at (h,k)
r² = (h - 0)² + (k - 0)²
r² = (h - 6)² + (k - 0)²
r² = (h - 6)² + (k - 4)²

Equating the equations
h² + k² = (h - 6)² + k²
h = 3

(h - 6)² + k² = (h - 6)² + (k - 4)²
k = 2

Therefore, the center of the circle is at (3,2).

Which formula represents the hyperbola on the graph shown below? Note: Answer choices and graph attached below...

Answers

Answer:

Your answer choice is appropriate

Step-by-step explanation:

The orientation is vertical, so the parent function is

... y² - x² = 1

The vertical offset is -3 and the horizontal offset is positive, so the variables will be of the form (y+3)² and (x-something)². At this point, you're able to choose the correct answer.

The distance center to vertex is 13, so we know the y-term denominator is 13². We cannot tell from this graph what the x-term denominator should be, but all the answer choices are in agreement that it should be 81.

The appropriate choice is ...

... (y+3)²/169 - (x-2)²/81 = 1

Answer:

If you are looking for the answer to a graph that looks similar but slightly different, the answer is C.

This graph looks like the one above, but it is inverted, the top hyperbola reaches 15, and the bottom reaches 10. This is correct for A.P.E.X

Hope this helps I couldn't find it anywhere else on brainly.
