Answer: 7

Step-by-step explanation:

Remember PEMDAS. Parentheses, exponents, multiplication & division (left to right), addition & subtraction (left to right). Also remember to switch the sign when working with negative numbers [ex. 2 - (-2) switches to 2 + 2, 2 + (-2) switches to 2 - 2), etc]

So:

9 + (-4) - (-2) - (7 × 0)

9 - 4 + 2 - 0

5 + 2

Write the equation of the ellipse with center (4,2), vertex (9,2), and focus (4+2sqrt5,2)

dangina [55]

Answer : option B

Given: center (4,2), vertex (9,2), and focus (4+2sqrt5,2)

The distance between vertex and center is 9-4 = 5

Center is (h,k) so h= 4 and k =2

focus is (h+c,k)

From the given focus (4+2sqrt5,2), c= 2sqrt(5)

Standard form of equation is

$\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}=1$

h= 4, k=2, a=5, c=2sqrt(5), we need to find out b

$c^2 = a^2 - b^2$

$b^2 = a^2 - c^2$

$b^2 = 5^2 - (2\sqrt{5})^2$

$b^2 = 25 - 20$

b^2 = 5

plug in all the values

$\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}=1$

$\frac{(x-4)^2}{25} + \frac{(y-2)^2}{5}=1$

Option B is correct

Find slope of a line using points (2,0) and (4,3)

Lilit [14]

The slope of the line would be 3/2 because the slope formula would be y2-y1/x2-x1 so 3-0=3 and 4-2=2 so 3/2

Hope this helps
