what is the distance rounded to the nearest tenth between the points (2 -2) and (6 3)
Answer:
The distance between the points is approximately 6.4
Step-by-step explanation:
The given coordinates of the points are;
(2, -2), and (6, 3)
The distance between two points, 'A', and 'B', on the coordinate plane given their coordinates, (x₁, y₁), and (x₂, y₂) can be found using following formula;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Substituting the known 'x', and 'y', values for the coordinates of the points, we have;
[tex]l_{(2, \, -2), \ (6, \, 3) } = \sqrt{\left (3-(-2) \right )^{2}+\left (6-2 \right )^{2}} = \sqrt{5^2 + 4^2} = \sqrt{41}[/tex]
Therefore, the distance between the points, (2, -2), and (6, 3) = √(41) ≈ 6.4.
Find the measure of the exterior angle in the following triangle. DUE SOON PLZ HELP WITH STEP BY STEP
Answer:
The measure of an exterior angle = 125°
Hence, option A is correct.
Step-by-step explanation:
As the given triangle is a right-angled triangle ΔABC.
Given the angles
m∠A = 35°m∠C = 90°We know that the sum of angles in a triangle is 180°.
Thus,
m∠A + m∠B + m∠C = 180°
substituting m∠A = 35° and m∠C = 90° in the equation
35° + m∠B + 90° = 180°
125 + m∠B = 180°
subtract 125 from both sides
125 + m∠B - 125 = 180° - 125
m∠B = 55°
Thus, the measure of angle B is:
m∠B = 55°
As the exterior angle of the given triangle is adjacent to m∠B = 55°.
We know that the exterior angle of a triangle is equal to the sum of two opposite interior angles.
Here,
∠A and ∠C are two opposite interior angles of the exterior angle.
Thus,
The measure of an exterior angle is equal to the sum of two opposite interior angles.
as
m∠A = 35°m∠C = 90°so
Exterior angle = m∠A + m∠C
= 35° + 90°
= 125°
Thus, the measure of an exterior angle = 125°
Hence, option A is correct.
Solve for the value of a.
Answer:
a=11
Step-by-step explanation:
So, the line that (9a+6) and 75 are sharing is straight, meaning that it is 180 degrees. Also, (9a+6) and 75 are sharing the line. Even though we don't know there exact measurements, when know that by adding them together we will get 180 degrees.
1. (9a+6) + 75 = 180
2. 9a + 81 = 180
3. 9a = 99
4. a = 11

THE THREE SIDES OF A TRIANGULAR LOT
ARE MEASURED TO BE APPROXIMATELY 100.52
FT, 15.321 FT AND 143.250 FT LONG. FIND THE
APPROXIMATE PERIMETER OF THE LOT
Answer:
259.09 feet
Step-by-step explanation:
Given that,
The three sides of a triangular lot are measured to be 100.52 ft, 15.321 ft and 143.250 ft.
We need to find the perimeter of the lot.
We know that,
Perimeter = sum of all sides
P = 100.52 + 15.321 + 143.250
P = 259.09 feet
So, the required perimeter of the lot is 259.09 feet.

Do not round any intermediate computations, and round your answer to the nearest cent.?
Answer:
1,717,351cents
Step-by-step explanation:
Using the compound interest formula
A = P(1+r/n)^nt
P = 8000
r = 14.5% = 0.145
n = 6/12 = 1/2 (semi annually)
t = 6years
Substitute
A = 8000(1+ 0.145/0.5)*(0.5)(6)
A = 8000(1+0.29)^3
A = 8000(1.9)^3
A = 8000(2.146689
A = 17,173.512
Hence the amount owned to the nearest cent is 1,717,351cents

N2 + 3H2 → 2NH3
How many moles of NH3 could you make with 4.2021 g of N2?
2. 2Na + Cl2 → 2NaCl
How many moles of Cl2 do you need to use in order to react with 34.485 g of Na?
3. H2SO4 + 2NaNO2 → 2HNO2 + Na2SO4
How many grams of NaNO2 do you need in order to make 24.14714 g of Na2SO4?
4. 2Na + 2H2O → 2NaOH + H2
How many grams of NaOH could you make with 8.0465 g of Na?
5. 2Mg + O2 → 2MgO
If you are burning 5.8332 g of Mg, how many grams of MgO will this make?
6. FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl
How many grams of NaCl could you make with 2.43306 g of FeCl3?
Step-by-step explanation:
1. N2 + 3H2 → 2NH3
How many moles of NH3 could you make with 4.2021 g of N2?
From the reaction;
1 mol of N2 produces 2 mol of NH3
1 mol of N2 = 14g of N2
14g of N2 produces 2 mol of NH3
4.2021 g of N2 produces x mol of NH3
14 = 2
4.2021 = x
x = 4.2021 * 2 / 14 = 0.6003 mol of NH3
2. 2Na + Cl2 → 2NaCl
How many moles of Cl2 do you need to use in order to react with 34.485 g of Na?
From the equation of the reaction;
2 mol of Na reacts with 1 mol of Cl2
1 mol of Na = 23g of Na
2 mol of Na - 46g of Na
46g of Na reacts with 1 mol of Cl2
4.485 g of Na reacts with x mol of Cl2
46 = 1
4.485 = x
x = 4.485 * 1 / 46 = 0.0975 mol of Cl2
3. H2SO4 + 2NaNO2 → 2HNO2 + Na2SO4
How many grams of NaNO2 do you need in order to make 24.14714 g of Na2SO4?
From the reaction;
2 mol of NaNO2 produces 1 mol of Na2SO4
2 mol of NaNO2 = 68.995 g/mol * 2mol = 137.99g
1 mol of Na2SO4 = 142.04 g
137.99g of NaNO2 produces 142.04 g of Na2SO4
xg of NaNO2 produces 24.14714 g of Na2SO4?
137.99 = 142.04
x = 24.14714
x = 24.14714 * 137.99 / 142.04 = 23.459g
4. 2Na + 2H2O → 2NaOH + H2
How many grams of NaOH could you make with 8.0465 g of Na?
From the reaction;
2 mol of Na produces 2 mol of NaOH
2 mol of Na = 23g/mol * 2mol = 46g
2 mol of NaOH = 40g/mol * 2 = 80g
46 g of Na produces 80g of NaOH
8.0465 g of Na produces xg of NaOH
46 = 80
8.0465 = x
x = 8.0465 * 80 / 46 = 13.994g
5. 2Mg + O2 → 2MgO
If you are burning 5.8332 g of Mg, how many grams of MgO will this make?
From the reaction;
2 mol of Mg produces 2 mol of MgO
2 mol of Mg = 24 g/mol * 2mol = 48g
2 mol of MgO = 40.3 g/mol * 2mol = 80.6g
48g of Mg produces 80.6 g of MgO
5.8332 g of Mg produces xg of MgO
48 = 80.6
5.8332 = x
x = 5.8332 * 80.6 / 48 = 9.8g
6. FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl
How many grams of NaCl could you make with 2.43306 g of FeCl3?
From the reaction;
1 mol of FeCl3 produces 3 mol of NaCl
1 mol of FeCl3 = 162.2 g
3 mol of NaCl = 58.44 g/mol * 3 mol = 175.32 g
162.2g of FeCl3 produces 175.32 g of NaCl
2.43306 g of FeCl3 produces xg of NaCl
162.2 = 175.32
2.43306 = x
x = 2.43306 * 175.32 / 162.2 = 2.63g
Which equation represents a linear function?
A) x = y2
B) y – 2 = x2 + 5x
C) y = x3 + 1
D) 5x + 6y = 12
Answer:
D) 5x + 6y = 12
Step-by-step explanation:
x = y^2 is Not Linear (Find the degree of the equation to determine if linear.)
y - 2 = x^(2) + 5x is Not Linear (Find the degree of the equation to determine if linear.)
y = x^(3) + 1 is Not Linear (A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 3.
5x + 6y = 12 is Linear (Find the degree of the equation to determine if linear.)
