Answer:

256

Step-by-step explanation:

The intial value should be where it started which in this case would be when

t = 0

So if you make t = 0

h(0) = 16(0)^2+96(0)+256

h(0)= 256

A family goes grocery shopping every week. in a month the costs of the groceries are $72.42, $91.50, $58.99, and $69.02. 5. what

frozen [14]

1) Mean
The mean is given by the sum of the data divided by the number of data (4, in this case):
$\mu = \frac{1}{N} \sum x_i = \frac{1}{4}(72.42+91.50+58.99+69.02) = \frac{291.93}{4}=72.98 $$

2) Standard deviation
The standard deviation is given by:
$\sigma = \sqrt{ \frac{1}{N} \sum (x_i-\mu)^2 }$
where $\mu$ is the mean, that we already found at point 1), and N=4. Substituting data, we have:
$\sigma = \sqrt{ \frac{1}{4} ((-0.56)^2+(18.52)^2+(-13.99)^2+(-3.96)^2) } =$
$= \sqrt{ \frac{1}{4} (554.71)} = \sqrt{138.68} =11.78 $$

Sole for y k = p/2(y+w) y =

mojhsa [17]

Answer:

Answer: y = (2k -pw)/p

Step-by-step explanation:

$k = \frac{p}{2} (y + w)$

multiply 2 on both sides:

$k \times 2 = 2 \times \frac{p}{2} (y + w) \\ \\ 2k = p(y + w)$

open the bracket:

$2k = py + pw$

subtract pw from both sides:

$2k - pw = (py + pw) - pw \\ 2k - pw = py$

divide p on both sides:

$\frac{2k - pw}{p} = \frac{py}{p} \\ \\ y = \frac{2k - pw}{p}$

You select a card at random from the cards that make up the word "replacement". Without replacing the card, you choose a second

lutik1710 [3]

Answer:

The probability is 14/55

Step-by-step explanation:

The word replacement contains 11 letters.

In which 4 letters are vowel = e,a,e,e

And 7 letters are not vowel = r,p,l,c,m,n,t

The probability of getting the vowel in the first try = 4/11

The probability of getting something that is not a vowel = 7/10.

The denominator is one less because the vowel card is not replaced, meaning there is one less card to choose from.

Multiply the values:

=4/11 * 7/10

=28/110

=14/55

The probability is 14/55....

the area of a rectangle is 42.15 square meters. if the length is 21 meters, what is perimeters of the rectangle?

Vsevolod [243]

Answer:

perimeters of the rectangle=p=46.014 metres

Step-by-step explanation:

Given that:

Length (l) = 21 m

Area of rectangle(A) = 42.15 meter-square

Width (w)=?

Required data:

Perimater of Rectangle=p=?

Calculation:

As we know that Area of rectangle=A=l*w

Putting the value we get

42.15 m(square)=(21 m)*w

or w=42.15/21

or w=2.007 m

Now to find perimters of rectangle we know that

p=2(l + w) metres

putting the values

p=2(21+2.007) metres

p=2(23.007) metres

p=46.014 metres
