Mathematics
1 answer:
laila [671]3 years ago
4 0

Answer:

7

Step-by-step explanation:

we use BODMAS which means bracket of division multiplication addition and subtraction.

we do the calculation that's in the brackets first. and then we do rest.

(4-2)2+4-1

= 2*2+4-1

= 4+4-1

= 8-1

= 7

what is the probability of (A) if P(AnB) =.20; P(AnC) =.16; and P(AnD) =.11 and we assume "A" can occur simultaneously only with
NemiM [27]
<span>the probability of (A)
P(A)=</span>P(AnB)*P(AnC)*<span>P(AnD)
P(A)=0.20*0.16*0.11=0.0035---- > 0.35%

the answer is 
the P(A)=0.35%</span>

I need help with this question. I cannot find any equations that work....
lidiya [134]

Answer:

  see the attachments for the graph(s)

  • y = -1/6(x -3)^2 +6
  • y = -1/6(x +3)(x -9)
  • y = -1/6x^2 +x +9/2

Step-by-step explanation:

1) The point at (3, 6) is on the vertical line that is halfway between the zeros at x=-3 and x=9, so it represents the vertex of the function. That knowledge, with any of the other points, lets you write the vertex form of the equation.

  y = a(x -3)^2 +6

Using the point (0, 4.5), we can find the value of 'a':

  4.5 = a(0 -3)^2 +6

  -1.5 = 9a

  -1.5/9 = a = -1/6

So, the vertex form of the equation is ...

  y = -1/6(x -3)^2 +6

A graph of this is shown in the attachment.

__

2) Now that we know the leading coefficient is -1/6, we can write the equation in "intercept form" (factored form) as ...

  y = -1/6(x +3)(x -9)

In this form, each zero (p) gives rise to a factor (x-p).

The second attachment shows the graph of this.

__

3) We can also write the equation in standard form, by expanding the one in (2) above:

  y = -1/6(x^2 -6x -27)

  y = -1/6x^2 +x +9/2

The third attachment shows the graph of this.

The rectangular prism shown has a length of 10 cm, a width of 10 cm, and a height of 6 cm. Find the length of the inner diagonal
melamori03 [73]
<h3>Answer:</h3>

15.36 cm

<h3>Explanation:</h3>

The Pythagorean theorem tells you ...

... AC² = AB² + BC² . . . . . relation for face diagonal

... AD² = AC² + CD² . . . . . relation for space diagonal

Subsituting the expression for AC² given by the first equation, the second equaiton becomes ...

... AD² = AB² + BC² + CD²

... AD² = (100 cm²) + (100 cm²) + (36 cm²) = 236 cm²

Taking the square root, we have ...

... AD = √236 cm = 2√59 cm

... AD ≈ 15.36 cm
