What is the directrix of the following graph?<br> X = -3<br> Y= 3<br> Y = -3<br> X = 3

kaheart [24]

Answer:

y = 3

Step-by-step explanation:

The vertex of the parabola is (1,4) and the axis of the parabola is parallel to the positive y-axis.

So, the equation of the parabola will be (x - 1)² = 4a(y - 4) ....... (1)

Now, we have to get the value of a since the equation id the directrix is y = 4 - a.

Now, the parabola passes through the point (3,5) {Obtained from the graph).

Therefore, from equation (1), we get, 2² = 4a × 1, ⇒a = 1

Therefore, the equation of the directrix is y = 4 - 1 = 3. (Answer)

Can you workout this problem

Vinil7 [7]

Hi,

Work:

Equation;

$35 - 3 \times {10}^{2} \div 20$
1. Write division as fraction.

$35 - \frac{3 \times {10}^{2} }{20}$

2. Evaluate the power of 10².

$35 - \frac{3 \times 100}{20}$

3. Reduce the fraction with 20.

$35 - \frac{3 \times 100}{20} = 35 - 3 \times 5$

4. Multiply.

$35 - 15$

5. Finally subtract and RESULT.

$35 - 15 = 20$

Hope this helps.

What is the area of this figure?

Margarita [4]

Answer:

218 cm²

Step-by-step explanation:

= high × wide

= 9 × 2

= 18

= 6 × (5+3)

= 6 × 8

= 48

= 8 × (11+5+3)

= 8 × 19

= 152

area throughout

= 152 + 48 + 18

= 218 cm²
