From 10 to 23, all you do is write in radical form.
For example, number 10, the answer would be \sqrt[5]{y}
The denominator, 5, goes on top of that radical sign and the 1 is the exponent of y. That's what you have to do for 10 to 23.

Now 24 to 39 is just the opposite. You change it to exponent form.
For example, number 24, the answer would be x^{ \frac{1}{3} } 

For 40 to 47, you have to neutralize the negatives or get rid of it, so you have to use the rule of negative exponents.
For example, number 40, the answer would be
 \frac{1}{x^{ \frac{1}{3} } }

For 48 to 55, you use multiply it but when multiplying exponents, you have to add.
For example, number 48, the answer would be
5^{ \frac{6+1}{8} } = 5^{ \frac{7}{8} }
You don't need to multiply the two 5s because they are the bases.
Hope this helps.

A parabola opening up or down has vertex (0,0) and passes through (4,2). Write it’s equation in vertex form
marshall27 [118]

Equation in vertex form, y= (-1/4) x² + 4

<u>Step-by-step explanation:</u>

 we have the equation,

y = ax² + 4     ( we need to find "a")

Now we have,

   2 = a(4)2 + 4

   2 = a (8)+ 4

   2-4 = 8a

   -2= 8a

   a= -1/4

Substituting the value of "a" in the equation,  we have

           y = (-1/4)(x- 0)² + 4  (or) y= (-1/4) x² + 4

 The parabola is opens downward. Therefore the vertex is above the x-axis and then the parabola passes through a point below the x-axis.

       Equation in vertex form= y= (-1/4) x² + 4

Andrews [41]

Answer:

all angles will be 200, 50 , 40 and 70 - hope this helped :)

Step-by-step explanation:

everything equals to 360 after added together

360 - 250 = 110

110 divided by 11 = 10

4:7 (x 10)

40:70

the other angels will be 40 and 70
