Based on the calculations, the radius of this circle with the given equation is equal to 5 units.
Given the following data:
[tex]x^2+y^2+8x-6y+21=0[/tex]The equation of a circle.Mathematically, the standard form of the equation of a circle is given by;
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where:
h and k represents the coordinates at the center.r is the radius of a circle.Expanding the equation, we have:
[tex]x^2+y^2-2hx-2ky+(h^2+k^2-r^2)=0\\\\r=\sqrt{h^2+k^2}[/tex]
Comparing the terms, we have:
[tex]-2hx = 8x\\\\-2h=8\\\\h=\frac{8}{-2}[/tex]
h = -4
[tex]-2ky = -6y\\\\-2k=6\\\\k=\frac{6}{-2}[/tex]
k = 3.
Now, we can determine the radius:
[tex]r=\sqrt{-4^2+3^2}\\\\r=\sqrt{16+9} \\\\r=\sqrt{25}[/tex]
r = 5 units.

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.

The lagrange corporation had the following budgeted sales for the first half of the current year: cash sales credit sales january $70,000 $340,000 february $50,000 $190,000 march $40,000 $135,000 april $35,000 $120,000 may $45,000 $160,000 june $40,000 $140,000 the company is in the process of preparing a cash budget and must determine the expected cash collections by month. 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
Total cash collected during January=$331,500
Inconclusion the total cash collected during january by lagrange corporation would be:$331.500.

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.

What is the value of x? sin64°=cosx enter your answer in the box. x = °
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°
