f(x) = −16x2 + 24x + 16 Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points) WILL GIVE BRAINLIEST

castortr0y [4]

Answer:

Step-by-step explanation:

f(x) = −16x2 + 24x + 16 = 0 can be reduced to -2x^2 + 3x + 2 = 0 and then to 2x^2 - 3x - 2 = 0. Solve this for x using the quadratic formula:

The discriminant is b^2 - 4ac = (-3)^2 - 4(2)(-2) = 9 + 16 = 25.

Therefore the roots are:

-(-3) ± √25 3 ± 5

x = ----------------- = ------------ => x = 2 and x = -1/2

2(2) 4

The x-intercepts are points: (2, 0) and (-1/2, 0)

Because the coefficient of the x^2 term is negative, this graph opens down and the vertex represents a maximum.

To graph this function, find and plot the vertex. It is exactly halfway between the x-intercepts, that is, at x = 1 1/4, for which the y value is 21:

vertex and maximum at (5/4, 21)

Finally, find the y-intercept. Let x = 0; we find that y = 16. The y-intercept is 0, 16)

We now have four points on the graph and know where the maximum is. Plot this max (5/4, 21) and the x-intercepts (2, 0) and (-1/2, 0), and finally the y-intercept. Draw a smooth curve through these points, remembering that the graph is symmetrical about the axis of symmetry x = 5/4.

To raise money, the Boy Scouts bought 190 kg of taffy for $723.90. They sold the tafty in 400 g bags

babunello [35]

They made profit of $\$834.10$ by selling 190 kg of taffy in 400 g bags at rate of $\$3.28$ each.

<u>Solution: </u>

Given that

To raise money, the Boy Scouts bought 190 kg of taffy for $\$723.90$ .

They sold the tafty in 400 g bags for $\$3.28\text{ each }$

Need to calculate the profit the made.

Cost price of 190 kg of taffy = $\$723.90$

As 1 kg = 1000 gram,

So 190 kg of taffy = $190\times 1000 = 190000\text{ grams of taffy }$

So cost price of 190000 gram of taffy = $\$723.90$

Now let us calculate number of 400 grams bags which can be made from 190000 grams of taffy

Number of 400 grams bags = $\frac{190000}{400}=475 \text { bags }$

Amount generated from 1 bag of 400 gram taffy = 3.28

So amount generated from 475 bags of taffy = $475\times3.28 = \$1558$

Selling price of 190000 grams of taffy = amount generated from 475 bags of taffy = $\$1558$

$\text{ Profit }= \text{ selling price }-\text{ cost price }= 1558-723.90 = \$834.10$

Hence they made profit of $\$834.10$ by selling 190 kg of taffy in 400 g bags at rate of $\$3.28$
