What are the key aspects of the graph of f(x) = x2 – b2, where b is a real number?
netineya [11]

Given equation is f\left(x\right)=x^2-b^2.

Now we need to find about what are the key aspects of the graph of f\left(x\right)=x^2-b^2, where b is a real number.

We know that square of any number is always positive.

then b^2 must be a positive number.

So that means for any real number b, as the value of b increases then graph of f(x) shifts downward by b^2 units as compared to the graph of parent function f\left(x\right)=x^2

Numbered disks are placed in a box and one disk is selected at random. If there are 6 red disks numbered 1 through 6, and 2 yell
Tatiana [17]

Answer:

\frac{3}{4}

Step-by-step explanation:

Total number of red disk=6

Total number  of yellow disk=2

Total disk=6+2=8

Odd number=1,3,5,7=4

Odd number on red disk=1,3,5=3

Probability,P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}

Using the formula

The probability of getting odd number disk=\frac{4}{8}=\frac{1}{2}

The probability of getting odd numbered  red disk=\frac{3}{8}

The probability of selecting a red disk,given that an odd numbered disk is selected=\frac{\frac{3}{8}}{\frac{1}{2}}=\frac{3}{8}\times 2=\frac{3}{4}

Using conditional probability

P(A/B)=\frac{P(A\cap B)}{P(B)}

Polygon XYZW is dilated by a scale factor of 2 with point T as the center of dilation, resulting in the image X′Y′Z′W′. If point
Anettt [7]
Since the whole figure including all the points is enlarged at the same time, the dilated figure will still have the same slope and that includes the fact that point T is still in line Y'Z'. The slope or shape does not change, only the size alters.The center of dilation is still at Point T in this case.

Y= -3x^2-24x-46 write in vertex form
mario62 [17]

ANSWER

y= -3{(x + 4)}^{2}  + 2

EXPLANATION

The given function is:

y= -3x^2-24x-46

Factor -3 for the first 2 terms.

y= -3(x^2 + 8x)-46

We add and subtract the square of the coefficient of x.

y= -3(x^2 + 8x +  {(4)}^{2} )  - - 3( {4)}^{2} -46

Factor the perfect square trinomial.

y= -3 {(x + 4)}^{2} )  + 48 -46

The vertex form is:

y= -3{(x + 4)}^{2}  + 2

How many pounds of Brazilian coffee costing $ 6 per pound must be mixed with 27 lbs of Columbian coffee costing $ 4 per pound to
grigory [225]

Answer:

11 2/3 pounds.

Step-by-step explanation:

Let x pounds be the amount in pounds of Brazilian coffee.

x + 27  is the amount of coffee in lbs after the mixing.

So ,working in  values of dollars, we have:

6x + 4*27 = 4.5(x + 27)

6x + 104 = 4.5x + 121.5

1.5x = 121.5 - 104 = 17.5

x = 17.5/1.5 = 11 2/3 pounds answer
