Sin and cosine of the acute angle are complementary trigonometric functions. This means that between these trigonometric functions, the rule of complementary acute angles applies: sin64° = cos(90°-64°) = cos26°
So, if we have given cos64° = cosx and we want to determine the value of the acute angle x, given the complementarity of the angles to 90 degrees, the required value of the angle x is 26°.
The answer is: x = 26°

Which of the indicators on the chart above tell(s) us that Australia and New Zealand are highly developed countries?
A.
per capita GDP
B.
unemployment rate
C.
infant mortality rate
D.
all of the above
Answer:
Answer: D
GDP per capita is a measure of a country's economic output that accounts for its number of people.
The unemployment rate is defined as the percentage of unemployed workers in the total labor force.
The infant mortality rate is the number of deaths under one year of age.
Given the above information, a country with a higher GDP would have a more stable economy aiding in growth. A lower unemployment rate would show a surplus of jobs indicating, once again, a steady and growing economy. Lastly, a lower infant mortality rate would show access to advanced medicine and a highly trained medical field. All three of these examples are indicators of a highly developed country.

To this end, the following information has been assembled: collections on sales: 60% in month of sale 30% in month following sale 10% in second month following sale the accounts receivable balance on january 1 of the current year was $70,000, of which $50,000 represents uncollected december sales and $20,000 represents uncollected november sales. The total cash collected during january by lagrange corporation would be:
Assuming $20,000 represents uncollected november sales. The total cash collected during january by lagrange corporation would be:$331.500.
Total cash collectedFirst step
Total Credit Sales in December= $50,000/40%
Total Credit Sales in December= $125,000
Second step
Total cash collected during January = Cash sales of January + (60% x Credit sales of January) + (30% x Credit sales of December)+ Uncollected November sales
Let plug in the formula
Total cash collected during January = $70,000 + (60% x $340,000) + (30% x $125,000) + $20,000
Total cash collected during January=$70,000+204,000+37,500+$20,000

The elements on the leading diagonals are: 4, -5 and -2
The elements under the leading diagonals are 0, 0 and 0
When the elements under the leading diagonals are 0, then the augmented matrix is row echelon form

How many iron atoms are present in 3.0 mol of iron metal?
Answer:
There are 1.806×10²⁴ atoms in 3 moles of iron.
Explanation:
Step 1:
Data obtained from the question
Number of mole of Fe = 3 moles
Number of atom =?
Step 2:
Determination of the number of atom.
From Avogadro's hypothesis, we understood that:
1 mole of Fe = 6.02×10²³ atoms
Therefore,
3 moles of Fe = 3 × 6.02×10²³ atoms
3 moles of Fe = 1.806×10²⁴ atoms
Thus, 3 moles of iron, Fe contains 1.806×10²⁴ atoms.

Consider a buffer made by adding 132.8 g of nac₇h₅o₂ to 300.0 ml of 2.31 m hc₇h₅o₂ (ka = 6.3 x 10⁻⁵) what is the ph of the buffer after 0.750 mol of h⁺ have been added?
The ph of the buffer solution given after 0.750 mol of H⁺ have been added is; 4.34
What is the PH of the Buffer?pKa = -log(Ka) = 4.20
[A⁻] = [NaC₇H₅O₂]
[HA] = [HC₇H₅O₂]
Concentration of NaC₇H₅O₂ in the preferred buffer solution is;
[132.8g/(144.11 g/mol * 300 mol)] * 1000 mL/1 L = 3.07 M
Formula for the PH here is;
pH = pKa + log [A⁻/HA]
Thus;
pH = -log(6.3 x 10⁻⁵) + log [3.07/2.31]
pH = 4.34
