Suppose sin u= x and u is between 0 and pi/2. what is sec u? ...?

1 answer:

4 0

The question should be accompanied with choices, below are the choices:

a) sqrt(1-x^2)
b) x/sqrt(1-x^2) 
c) sqrt(1-x^2)/x 
D) 1/sqrt(1-x^2)

The answer should be c) sqrt(1-x^2)/x .

cos u = sqrt (1 - sin^2 u) = sqrt(1 - x^2), and cot u = cos u / sin u.

Graph g(x), where f(x)=2x-5 and g(x)=f(x+1)

tigry1 [53]

Answer:

Graph g(x) = 2x - 3

Step-by-step explanation:

Plug in (x+1) to f(x) = 2x - 5:

g(x) = 2(x+1) - 5 = 2x + 2 - 5

g(x) = 2x - 3

GCF of 9ab^2 and 6bc^2

Alchen [17]

For this case we have that by definition, the GCF (Greatest Common Factor) is the largest integer that divides the numbers.

We have the following expressions:

$9ab ^ 2\\6bc ^ 2$

We find the factors of 9 and 6:

$9: 1,3,9\\6: 1,2,3,6$

Thus, the largest number that divides 9 and 6 is 3

It is also observed that "b" is the common variable of both expressions

Therefore, the GCF of the expressions is:

$3b$

Answer:

$3b$

The cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar

Alexus [3.1K]

Question:

The cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar.

Given:

Cost of 12 kg sugar = $240

To find?

cost of 3 kg sugar

Answer :

To find cost of 3kg sugar first we have to find cost of 1 kg sugar.

Cost of 1 kg sugar = Cost of total no. of sugar ÷Total sugar
Cost of 1 kg sugar = $240/12
Cost of 1 kg sugar = $20

Now Let's find cost of 3 kg sugar

Cost of 3kg sugar = total no of sugar ×Cost of 1 kg sugar

Cost of 3kg sugar = 3×$20

Cost of 3kg sugar = $60
