Answer:

at x = 10, $4x^{2} + 17x + 2 = 572$

Step-by-step explanation:

The given equation is $4x^{2} + 17x + 2$

Here, lets substitute the value of x = 10

So, the equation simplifies to ,

$4 \times (10)^{2} + 17(10) + 2$

= (4 x 100) + 170 + 2 = 400 + 170 + 2

= 572

So, at x = 10, $4x^{2} + 17x + 2 = 572$

Step-by-step explanation:

There are 6 different shapes

You want the outcome to be a Nonagon

You put the outcome as a ratio 1/6

1/6=0.1666667

0.1666667*100=16.6667%

Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?

viktelen [127]

To express a function of the form $f(x)= x^{2} +bx+c$ in vertex form $f(x)=a(x-h)^2+k$ where (h,k) is the vertex of the parabola, we need to find the vertex first.
To find the vertex we are going to use the vertex formula: $h= \frac{-b}{2a}$ , and $k$ will be the function evaluated at $h$ .
We can infer from our function that $a=1$ and $b=-2$ . So lets find $h$ :
$h= \frac{-b}{2a}$
$h= \frac{-(-2)}{2(1)}$
$h= \frac{2}{2}$
$h=1$
Now that we have $h$ , we can evaluate the function at 1 to find $k$ :
$f(x)=4+ x^{2} -2x$
$f(1)=4+(1)^2-2(1)$
$f(1)=4+1-2$
$f(1)=3$

We have the vertex (1,3) of our parabola, so we can use its vertex form:
$f(x)=a(x-h)^2+k$
$f(x)=1(x-1)^2+3$
$f(x)=(x-1)^2+3$

We can conclude that the vertex for of our parabola is f(x) = (x + 1)2 + 3.

Which statement is not used to prove that ΔABC is similar to ΔADE? triangles ABC and ADE in which point E is between points A an

Levart [38]

Answer:

The correct option is;

The sum of angles A and B are supplementary to angle C

Step-by-step explanation:

The statements are analysed as follows

1. Angle A is congruent to itself reflective property

Which shows that ΔABC and ΔADE have a common and equal angle

2. Segment ED and CB are parallel

From the transversal line passing EB and CB which shows that the angles ∠ADE and ∠ABC are equal and also ∠AED and ∠ACB are equal

The statement is used to prove similarity between the ΔABC and ΔADE

3. The sum of angles A and B are supplementary to angle C

The above statements relates to only ΔABC and i does not show similarity between ΔABC and ΔADE.

erma4kov [3.2K]

A) 180 would be expected to pass.
B) The standard deviation is 4.
C) 95% of people would fall between 172 and 188.
D) Yes, this is more than 3 standard deviations below the mean.

Explanation
A) Multiply the probability by the sample size:
0.6(300) = 180

B) Standard deviation is found by:
√n(p)(1-p)
For our data, we have:
√300(0.6)(0.4) = 4

C) Two standard deviations below the mean is 180-2(4) = 172; two standard deviations above the mean is 180+2(4)= 188.

D) Three standard deviations below the mean is 180-3(4) = 168; 134 is more than this below the mean. 99.7% of data fall within 3 standard deviations of the mean; 0.15% fall below this point, so yes, this is unusually low.
