The discriminant is b^2 - 4ac.
Find x-intercepts by setting y = 0 and solving for x.
With <span>0 = -4x^2 + 4x - 1, this implies that a = -4, b = 4, and c = -1.
               discriminant = 4^2 - 4(-4)(-1)
                                      </span><span>= 16 - 16
                                      = 0
The </span>discriminant of 0 means there is only one real solution to <span>0 = -4x^2 + 4x - 1.
So there is only one x-intercept.

Your answer is one x-intercept.

Use the formula x=b^2-4ac
a= -4 , b= 4 , c= -1
Plug in into your formula
(4)^2-4(-4*-1)
16-16
x=0
so the solution only has one x-intercept

using two of the number cards from the list, fill in the gaps so that the values are in ascending order
Mademuasel [1]

The two gaps of the series are 236 % and 2.41.

The series is 2(32/100) _, _ , 247/100.

We are given that the series is in ascending order.

Let the missing numbers be x and y respectively.

We know that  2(32/100) = 2.32 in decimal form and 247/100 is 2.47 in decimal form.

Hence, we can write,

2.32 < x < y < 2.47

The given options are:-

231 % = 231/100 = 2.31 < 2.32

Hence, it is not the answer.

0.42 < 2.31

Hence, it is not the answer.

236 % = 236/100 = 2.36 > 2.31

Hence, this is one of the answers.

34 % = 0.34

0.34 < 2.31

Hence, it is not the answer.

0.237 < 2.31

Hence, it is not the answer.

2.41 > 2.32

Hence, this is one of the answers.

24.2 % = 24.2/100 = 0.242 < 2.31

Hence, it is not the answer.

0.36 < 2.31

Hence, it is not the answer.

As, 2.36 < 2.41, hence,

x = 2.36 or 236 % and,

y = 2.41

NemiM [27]

Answer:

17.

Step-by-step explanation:

Statement: "ten more than the product of two and a number"

Translation: 10 + (2 * x)

x = 3.5

10 + (2 * 3.5)

= 10 + 7

= 17.

Hope this helps!

What is the Z-score for Paula if she got 1400 on the SAT, the mean was 1100 and the standard deviation was 275? step by step how
Setler [38]

mu = 1100 = population mean

sigma = 275 = population standard deviation

x = 1400 = raw score

z = z score

z = (x-mu)/sigma

z = (1400-1100)/(275)

z = 300/275

z = 1.0909090909091 approximately

z = 1.09

Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).

The positive z score is due to Paula's raw score being above the mean.

A swimming pool is to be drained. The pool is shaped like a rectangular prism with length 30 ft, width 18 ft, and depth 4 ft. Su
Licemer1 [7]

Answer:

10 hours (I am not positive)

Step-by-step explanation:

We first want to find the volume of pool which is 30 x 18 x 4 = 2160.

Then you are going to divide by 216 to find how many hours it takes to drain the whole pool. (I'm not that big of an expert)
