I had this question for a practice on edmentum lol

If your multiple choice answers had the choice

“As x approaches positive infinity, h(x) approaches positive infinity”

Thats your answer.

Explanation: Function h is a transformation of the parent exponential function, f(x)=2^x, and has been translated 5 units to the rights. Even though it is transformed, its end behavior is the same as that of the parent function

Let P be the parabola with focus (0,4) and directrix y=x.Write an equation whose graph is a parabola with a vertical directrix t

prisoha [69]

Answer:

y²=4√2.x

Step-by-step explanation:

The focus is at (0,4) and directrix is y=x or x-y =0, for a parabola P.

The distance between the focus and the directrix of the parabola P is

$\frac{ |0-4| }{\sqrt{(1)^{2}+(-1)^{2} } }$ = $\frac{4}{\sqrt{2} }$

{Since the perpendicular distance of a point (x1, y1) from the straight line ax+by+c =0 is given by $\frac{ |ax1+by1+c| }{\sqrt{a^{2}+b^{2} } }$ }

Let us assume that the equation of the parabola which is congruent with parabola P is y²=4ax

{Since the parabola has vertical directrix}

Hence, the distance between focus and the directrix is 2a = $\frac{4}{\sqrt{2} }$ , {Two parabolas are congruent when the distances between their focus and the directrix are same}

⇒ a=√2

Therefore, the equation of the parabola is y²=4√2.x (Answer)

At a local preschool there is s as ratio of 3 boys to every 4 girls. If their are 245 total preschoolers enrolled how many are b

Zepler [3.9K]

Number of boys enrolled is 105

Solution:

Given that, At a local preschool there is s as ratio of 3 boys to every 4 girls

There are 245 total preschoolers

Ratio of boys and girls = 3 : 4

Number of boys : number of girls = 3 : 4

Let the number of boys be 3x

Let the number of girls be 4x

Total number of preschoolers = 245

Therefore,

number of boys + number of girls = 245

3x + 4x = 245

7x = 245

x = 35

Number of boys = 3x = 3(35) = 105

Thus number of boys is 105

Solve.

Snezhnost [94]

Answer:

v = -1

Step-by-step explanation:

First, you will need to solve it step-by-step:

(4v − 9)(1 + v) = 0

Next, you need to simplify both sides of the equation:

4v(2) − 5v − 9 = 0

Now, factor the left side of equation:

(4v − 9)(v + 1) = 0

The last thing you need to do is to set all of the factors to equal to zero:

4v − 9 = 0 or v + 1 = 0

So, that means that you answer:

v=9/4 or in your case, v = −1
