Answer:

f(3) = 23

Step-by-step explanation:

To evaluate f(3) substitute x = 3 into the expression

f(3) = 2(3)² + 5\sqrt{3-2}

     = (2 × 9) + (5 × \sqrt{1})

    = 18 + (5 × 1) = 18 + 5 = 23

What is the prime factorization for 356
densk [106]

Answer:

2² • 89

The prime factors are: 2 x 2 x 89

or also written as { 2, 2, 89 }

Written in exponential form: 2² x 891

Step-by-step explanation:

56 ÷ 2 = 178 - No remainder! 2 is one of the factors!

178 ÷ 2 = 89 - No remainder! 2 is one of the factors!

89 ÷ 2 = 44.5 - There is a remainder. We can't divide by 2 evenly anymore. Let's try the next prime number

89 ÷ 3 = 29.6667 - This has a remainder. 3 is not a factor.

89 ÷ 5 = 17.8 - This has a remainder. 5 is not a factor.

89 ÷ 7 = 12.7143 - This has a remainder. 7 is not a factor.

What is the greatest fraction you can make using the digits 4, 7, and 9?
wel

Answer:

  (7^9)/4 = 40,353,607/4

Step-by-step explanation:

Assuming each digit is used once and exponentiation is allowed, the largest numerator and smallest denominator will result in the largest fraction.

__

If other functions, such as factorial are allowed, then there might need to be a limit on the number of times they are applied. For example,

  (7!)^(9!)/4 has about 1 million digits

something like ...

  ((7!)^(9!))!/4 has many more digits than that

and you can keep piling on the factorial symbols to any desired depth.

Weights of cars passing over a bridge part 2<br>​
DaniilM [7]

Step-by-step explanation:

The solution to this problem is very much similar to your previous ones, already answered by Sqdancefan.

Given:

mean,  mu = 3550 lbs (hope I read the first five correctly, and it's not a six)

standard deviation, sigma = 870 lbs

weights are normally distributed, and assume large samples.

Probability to be estimated between W1=2800 and W2=4500 lbs.

Solution:

We calculate Z-scores for each of the limits in order to estimate probabilities from tables.

For W1 (lower limit),

Z1=(W1-mu)/sigma = (2800 - 3550)/870 = -.862069

From tables, P(Z<Z1) = 0.194325

For W2 (upper limit):

Z2=(W2-mu)/sigma = (4500-3550)/879 = 1.091954

From tables, P(Z<Z2) = 0.862573

Therefore probability that weight is between W1 and W2 is

P( W1 < W < W2 )

= P(Z1 < Z < Z2)

= P(Z<Z2) - P(Z<Z1)

= 0.862573 - 0.194325

= 0.668248

= 0.67 (to the hundredth)
