Answer:

An parabola has focus at( -43/4, 4) and directrix x = -13/4.

The vertex is exactly between focus and directrix, then:

=> vertex ([(-43/4 + (-13/4)]/2, 4) = (-28/4, 4) = (-7, 4)        

The directrix x = -13/4 is a vertical line, this parabola is thus a sideways parabola (that looks left or right, not upward or download). It has the equation form as following:

4p(x – h) = (y – k)^2

with vertex(h, k) and p is distance from vertex to directrix

p = |-7 - (-13/4)|  = |-15/4| = 15/4.

However, the vertex (-7, 4) is on the left of directrix x =-13/4, then this parabola faces left. Therefore p should be -15/4, not 15/4

=>4*(-15/4)*(x - (-7)) = (y - 4)^2

=>Solution: -15(x + 7) = (y - 4)^2

Hope this helps!

Ten slips of paper numberd 1 through 10 are placed in a bag. You draw a slip at random and draw another without replacing the fi
Bogdan [553]

Answer:

Probability that both numbers are odd =2/9

Step-by-step explanation:

Odd numbers are numbers such that, when they divide 2, there is a remainder.

Ten slips of paper numbered 1 through 10 are placed in a bag.

In number one to ten, the odd numbers are 1, 3,5,7 and 9

They all divide 2 and leaves a remainder.

Total number of odd numbers is 5

Total number of both odd and even numbers from one through 10 is 10

Probability of picking an odd number

= number of odd numbers/ total numbers.

Probability of picking an odd number

= 5/10= 1/2

Probability of picking another odd number without replacement is 4/9

Probability that both numbers are odd = 1/2 × 4/9 =2/9

(x+5)to the second power -4=12​
Softa [21]

Answer:

x = 3i

Step-by-step explanation:

(x+5)² - 4 = 12

simplify (x+5)²

x × x + 5 × 5 - 4 = 12

x² + 25 - 4 = 12

x² + 21 = 12

combine the like terms

x² = 12 - 21

x² = -9

square root both sides to solve for x

√x² = √-9

the square cancels the square root, so we have

x = √-9

x = 3i

A student took a system of equations, multiplied the first equation by and the second equation by , then added the results toget
Ierofanga [76]

Answer:

option A

-2x + 4y = 4

-3x + 6y = 6

Step-by-step explanation:

In option A, if the student multiply the first equation by 3 and the second equation by -2, then the equations become

-6x+12y = 12 and

6x-12y =-12

If she adds both equations, she will get 0 = 0

This means that the system has infinite number of solutions.

Hence, the student could have started with equations -2x + 4y = 4 and -3x + 6y = 6.
