Andy and Sam are saving money to go on their senior trip. The amount of money that Andy will have at the end of each week, w, ca

n be expressed at A(w) = 20w + 300. The amount of money that Sam will have at the end of each week, w, can be expressed at S(w) = 15w + 400. They have decided to combine their savings accounts. Write a function that expresses the total amount, T(w) they have in their savings account at the end of each week. A) T(w) = 5w - 100 B) T(w) = 35w + 700 C) T(w) = -5w + 100 D) T(w) = 300w2 + 12500w + 120000

The weight distribution of parcels sent in a certain manner is normal with mean of 12 lb and standard deviation of 3 lb. The par
kicyunya [14]

Answer:

21.16

Step-by-step explanation:

Starting from the theory we have the following equation:

fi*P(x

Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:

P( z \leq \frac{c-1-12}{3.5}) =0.99/fi

solving for "c", knowing that fi is a tabulating value:

\frac{c-13}{3.5}=0.99/fi\\\frac{c-13}{3.5}=2.33\\c-13=2.33*3.5\\c = 8.155 +13\\c = 21.155

therefore the value of c is equal to 21.16

find the equation of a cubic function whose graph passes through points (3,0) and (1,4) and is tangent to x-axis at the origin
Tomtit [17]

Answer:

y = -2x^2(x - 3)

Step-by-step explanation:

<em><u>Preliminary Remark</u></em>

If a cubic is tangent to the x axis at 0,0

Then the equation must be related to y = a*x^2(x - h)

<em><u>(3,0)</u></em>

If the cubic goes through the point (3,0), then the equation will become

0 = a*3^2(3 - h)

0 = 9a (3 - h)

0 = 27a - 9ah

from which h = 3

<em><u>From the second point, we get</u></em>

4 = ax^2(x - 3)

4 = a(1)^2(1 - 3)

4 = a(-2)

a = 4 / - 2

a = -2

<em><u>Answer</u></em>

y = -2x^2(x - 3)
