G(x) = -10x2+ 490 lesser x= greater x =

Mathematics
1 answer:
Sergeu [11.5K]3 years ago
7 0

Answer:

Greater x =+ 7

Lesser x = -7

Step-by-step explanation:

G(x) = -10x2+ 490

Let the left side = 0

So we have

0= -10x2+ 490

Solving the above now by allowing the variable with the coefficient of x cross the equal sign.

10x²= 490

Dividing by 10

X²= 490/10

X² = 49

Taking the root of both sides

X= √49

X = + 7or -7

Bigger x =+ 7

Smaller x = -7

In the xy-coordinate plane shown, line L passes through point C and has a slope of -2. A dilation of line {with center A and a s
masya89 [10]

Answer:

C' (-4 , 2)

slope of new line = line "L" = -2

Step-by-step explanation:

C (x₀,y₀): (0,2)    dilation center (h,k): (2,2)     scale factor (sf): 3

C' (x,y)

x = 2 + 3*(0-2) = -4            x = h + sf*(x₀ - h)

y = 2 + 3*(2-2) = 2             y = k + sf*(y₀ - k)

C' (-4 , 2)

slope of new line = line "L" = -2

The average birth weight of elephants is 200 pounds. Assume that the distribution of birth weights is Normal with a standard dev
zhenek [66]

The birth weight of elephants at the 85th percentile is 262.16 pounds

<h3>What is the standard deviation?</h3>

Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.

Given that:-

The average birth weight of elephants is 200 pounds    \mu = 200

The deviation of 60 pounds.                                              \sigma = 60

The birth weight of elephants at the 85th percentile.      z = 85%= 1.036

Now from the formula of z-score:-

z=\dfrac{x-\mu}{\sigma}\\\\\\z=\dfrac{x-200}{60}\\\\\\1.036\times 60=x-200\\\\\\x=\ \ 262.16\ pounds

Hence the birth weight of elephants at the 85th percentile is 262.16 pounds

What’s the greatest hundred you can multiply by 17 to get close to but not go over 821
Julli [10]

Answer:

48

Step-by-step explanation:

821 rounded down to 800

17 rounded up to 20

820/20 =41

20x41=820

17 x 41 = 697

17 x 51 = 867

Midpoints

697+867/2 = 782

41 +51/2 = 46

46 x 17 = 782

47 x 17 = 799

48 x 17 =816

49 x 17 =833

50 x 17 =850

So, the highest number is 48.

The closest we can get is 48 x 17=816 & without going over 821.

Dida bought a scratch ticket for $2.00. The potential payoffs and probability of those payoffs are shown below.
kakasveta [241]

9514 1404 393

Answer:

  (b)  $1.15

Step-by-step explanation:

The expected value is the sum of products of payoff and probability:

  $0×0.15 +0.50×0.5 +1.0×0.2 +2.0×0.1 +10×0.05

  = $0 +0.25 +0.20 +0.20 +0.50

  = $1.15 . . . . expected value of the scratch ticket
