Cos²x + sin2x - 1 = 0, 0° ≤ x ≤ 90°, tan x =​

Answers

Answer:

0 and arctan(0.5)

Step-by-step explanation:

if sin2x=2sinx*cosx and 1=sin²x+cos²x, then

cos²x+2sinxcosx-sin²x-cos²x=0;

2sinxcosx-sin²x=0; (to divide by cos²x)

2tanx-tan²x=0;

\left[\begin{array}{ccc}tan(x)=0\n tan(x)=1/2\end{array} \ => \ \left[\begin{array}{ccc}x=pi*n\nx=arctan(1/2)+pi*n\end{array} \ => \ \left[\begin{array}{ccc}x=0\nx=arctan(0,5)\end{array}

What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?

  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical equation is used to equate two expressions.
  • Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
  • For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.

Given is your dinner in London cost 82 British pounds

Then in U.S. dollars, the equivalent money will be equivalent to -

x = 82 pounds = 82 x 1.2286 = $100.74

x = $100.74

Therefore, in U.S. dollars, the equivalent money will be $100.74

There are 25 coins inside a container. Some of the coins are nickels, and the rest are quarters. The value of the coins is $4.05. Let n represent the number of nickels and q be for the number of quarters. What equation represents this problem?​

Answers

Answer:

  • n + q = 25
  • 0.05n + 0.25q = 4.05

Step-by-step explanation:

Two equations are required to represent this problem as posed.

1. An equation for the number of coins:

  n + q = 25

2. An equation for the value of the coins:

  0.05n + 0.25q = 4.05

Solving EquationsIf an elephant travels for 4 hours at
6.5 mph and a giraffe travels for 2
hours at ll mph, who covers more
distance?
E. elephant
F. giraffe
G. They travel the same distance.
H. cannot be determined based on the
information provided
Q2

Answers

The elephant; 6.5 mph for 4 hours equates to 26 miles, while the Giraffe only covers 22 miles (2*11)

Final answer:

The elephant covers more distance than the giraffe.

Explanation:

To determine who covers more distance, we need to calculate the distance traveled by each animal. The distance traveled can be calculated using the formula: distance = speed × time. For the elephant, the distance is 6.5 mph × 4 hours = 26 miles. For the giraffe, the distance is 11 mph × 2 hours = 22 miles. Since the elephant covers a greater distance, the answer is E. elephant.
