The next model of a sports car will cost 4.4% more that the current model. The current model costs $48,000, How much will the pr

podryga [215]

Answer:

$50,112. Increase is $2,112

Step-by-step explanation:

1st way. $48,000 x 1.044 = $50,112. 1.044 is the same thing as saying 104.4% of the total price in decimal form, which is what the new price would be when adding 4.4% to the 100% of the original price. To get the amount of increase just find the difference in the two. $50,112-$48,000 = $2,112

2nd way. $48,000 x .044. = $2,112 .044 is 4.4% in decimal form. So you found the increase here. Add the increase to the original price. $48,000 + $2,112 to get the new price of $50,112.

a quadratic equation has a discriminant of 12. which could be the equation? a.0 = –x2 8x 2 b.0 = 2x2 6x 3 c.0 = –x2 4x 1 d.0 = 4

Norma-Jean [14]

Answer:

Option b which is $2x^2+6x+3=0$

Step-by-step explanation:

We have been given the discriminant 12

We have to choose the equation which will satisfy the given discriminant.

We will consider all the given equation one by one

First we will take option a which is $-x^2+8x+2=0$

Discriminant from the equation we will find by the formula

$D=b^2-4ac$

Here, a=-1,b=8 and c=2 on substituting the values we will get

$D=8^2-4(-1)(2)=72$

Hence, option a is incorrect.

Now, we will consider option b which is $2x^2+6x+3=0$

Here, a=2,b=6 and c=3 on substituting the values we get

$D=(6)^2-4(2)(3)=12$

Hence, option b is correct

Therefore, option b is the required answer.

Solve each proportion. show your work. 2x/7 = 12/14

dybincka [34]

2x/7 = 12/14
Multiply both sides of the equation by 7:
2x = 84/14
Simplify:
2x = 6
Divide both sides by 2 and your answer is....
x = 3

(09.06 HC) The function H(t) = −16t2 + 112t + 24 shows the height H(t), in feet, of a cannon ball after t seconds. A second cann

erma4kov [3.2K]

PART A:

The table of h(t) and g(t) for the value of x between 4 and 7 inclusive are shown below.

The solution for h(x)=g(x) lies between x = 4 and x = 5, this is becuase the range of value given by h(4) and h(5) and g(4) and g(5).

The graph is shown in picture 2 to confirm this. The two functions intersect each other between x = 4 and x = 5

PART B:

The point of intersection is the point where the cannon balls will collide.
