\\ \sf\longmapsto f(x)=112-kx

  • f(-3)=121

Put -3 in f(x)

\\ \sf\longmapsto f(-3)=121

\\ \sf\longmapsto 112-k(-3)=121

\\ \sf\longmapsto 112+3k=121

\\ \sf\longmapsto 3k=9

\\ \sf\longmapsto k=3

What is the solution to the trigonometric inequality 2sin(x)+3>sin^2(x) over the interval 0<=x<=2pi radians?
densk [106]

Answer:

A 2-column table with 6 rows. Column 1 is labeled x with entries 1.99, 1.999, 1.9999, 2.0001, 2.001, 2.01. Column 2 is labeled f (x) with entries 0.505, negative 0.827, 0.306, negative 0.306, 0.827, negative 0.506.

For F (x) =3x+5 Evaluate f (0)
Slav-nsk [51]
F(0)= 5 because 3(0) is the same as 0 and you add 5 so f(0)= 5

Use Pascal’s triangle and binomial expansion strategies (x+y)^3
mariarad [96]
<h2>1. Pascal’s triangle</h2>

Pascal's triangle is an strategy in math that stands for a triangular array we use to solve problems of binomial coefficients. This strategy is called after the mathematician Blase Pascal. It consists in number patters. So in this problem we need to solve this following Pascal’s triangle strategy:

(x+y)^3

The strategy consists in building a triangle. So 1 is the first and last numbers in each row of Pascal’s Triangle. Next, every other  number in each row is formed when you add the two numbers directly above the  number, as shown in Figure below. So:

(x+y)^3=x^3+3x^2y+3xy^2+y^3

<h2>1. Binomial Expansion</h2>

A binomial is a polynomial having two terms. So binomial expansion is a method that stands for a formula that gives us a quick method of raising a binomial to a power. So, for n=3, the binomial expansion can be written as:

(x+y)^3=x^3+3x^2y+3xy^2+y^3

Mr.Krogman usually prices the umbrellas in his store $8 each.However,on a rainy day he increases the price by 75%.How much does
MA_775_DIABLO [31]
Calculator method:
75% as a decimal is 75/100= 0.75. So an increase of 75% is 100% + 75% which is the same as 1+0.75= 1.75. This is your multiplier, so now just do 8×1.75=$14
Non-calculator method:
Find out what 50% of 8 is, this can be done by halving 8 which gives you 4. Now find out what 25% of 8 is, this can be done by halving what you got for 50% (4), so 25% of 8 is 2. 50%+25%=75%, so (4+2)=6 is 75% of 8. Now just do 8+6= $14
The answer is in bold.
