Find the 63rd term of the arithmetic sequence 2,9,16
Answer:
a₆₃ = 436Step-by-step explanation:
[tex]a_1=2\\a_2=9\\d=a_2-a_1=7\\\\a_n=a_1+d(n-1)\\\\a_{63}=2+7(63-1)=2+7(62)=2+434=436[/tex]
The 63rd term of the given arithmetic progression is 436.
What is an Arithmetic progression?
An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. A sequence -
a₁ , a₂, a₃ , a₄ ...... aₙ
will be an arithmetic progression if -
a₂ - a₁ = a₃ - a₂ = a₄ - a₃ = d (constant) is called common difference of A.P. and a₁ = 'a' as the first term.
Given is the following sequence -
2, 9, 16, ..... nth term
First term [a] = 2
common difference [d] = 9 - 2 = 7
We can calculate the nth term of an A.P. using the formula -
a[n] = a + (n - 1)d
a[63] = a + (63 - 1) d
a[63] = 2 + 62 x 7
a[63] = 2 + 434
a[63] = 436
Therefore, the 63rd term of the given arithmetic progression is 436.

What is this the answer?
Answer:
14
It is 14 because the function of g equals 5 and the function of f equals 9
Answer:
c) 14
Step-by-step explanation:
f(x) = x²
f(-3) = (-3)² = -3 * - 3 = 9
g(x) = 2x - 3
g(4) = 2*4 - 3 = 8 - 3 = 5
g(4) + f(-3) = 5 + 9
= 14

if f(x)=2x^2-10, find f(-3)
Answer:
f(- 3) = 8
Step-by-step explanation:
To evaluate f(- 3), substitute x = - 3 into f(x) , that is
f(- 3) = 2(- 3)² - 10 = 2(9) - 10 = 18 - 10 = 8
The positions of two airplanes approaching an airport are plotted in a coordinate plane with the airport located at (0,0). The locations of the planes are
given by the coordinates (7, 2) and (-1, -8). Each grid square is 1 mile wide. How far apart are the approaching airplanes? Round your answer to the
nearest tenth of a mile.
Answer:
12.8 miles
Step-by-step explanation:
The distance is given by the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
d = √((-1 -7)^2 +(-8-2)^2) = √((-8)^2 +(-10)^2) = √(64 +100)
d = √164 ≈ 12.8
The planes are about 12.8 miles apart.
Answer: incorret
Step-by-step explanatioTo calculate the distance (d) use the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, - 5)

What is an equation of the line that passes through the point (8, 2) and is parallel to
the line x + 4y = 28?
Answer:
x+4y is not change because it's parallel what changes is the result 8 + 4 × 2 = 16 so the equation is x + 4y = 16
An equation of the line that passes through the point (8, 2) and is parallel to the line x + 4y = 28 is;
⇒ x + 4y = 16
What is Equation of line?
The equation of line with slope 'm' and y - intercept at point 'b' is given as;
⇒ y = mx + b
Given that;
The point is = (8 , 2)
The line is x + 4y = 28
Since, Slope of line to its parallel line is same.
Hence, We find the slope of given equation of line as;
x + 4y = 28
After solving for y;
y = -1/4 x + 7
Compare with y = mx + b we get;
Slope (m) = -1/4
Thus, Equation of the line that passes through the point (8, 2) and is parallel to the line x + 4y = 28 is;
y - 2 = -1/4 (x - 8)
4(y - 2) = - (x - 8)
4y - 8 = -x + 8
x + 4y = 16
So, An equation of the line that passes through the point (8, 2) and is parallel to the line x + 4y = 28 is;
⇒ x + 4y = 16

One triangle has angles that measures 45 degrees and 83 degrees. Another triangle has angles that measure 45 degrees and 42 degrees Are the triangles similar? How do you know?
Answer:
The two triangles are not similar
Step-by-step explanation:
Similar triangles have equal corresponding angles and proportion sides
Ex: If Δ ABC is similar to ΔXYZ, then
m∠A = m∠X, m∠B = m∠Y, m∠C = m∠Z[tex]\frac{AB}{XY}=\frac{BC}{YZ}=\frac{AC}{XZ}[/tex]In the given question
∵ One triangle has angles that measure 45° and 83°
→ Find the measure of the 3rd angle
∵ The sum of the measures of the angles of a triangle is 180°
∴ The measure of the 3rd angle = 180° - 45° - 83°
∴ The measure of the 3rd angle = 52°
∴ The measures of the angles of this triangle are 45°, 83°, 52°
∵ Another triangle has angles that measure 45° and 42°
→ Find the measure of the 3rd angle
∴ The measure of the 3rd angle = 180° - 45° - 42°
∴ The measure of the 3rd angle = 93°
∴ The measures of the angles of this triangle are 45°, 93°, 42°
∵ The two triangles have different measures of 2 angles
→ That means their corresponding angles are not equal
∴ The two triangles are not similar

Please solve 8.2(6x-3)=7(7x-1.2)
Answer:
x=81
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8.2(6x−3)=7(7x−1.2)
(8.2)(6x)+(8.2)(−3)=(7)(7x)+(7)(−1.2)(Distribute)
49.2x+−24.6=49x+−8.4
49.2x−24.6=49x−8.4
Step 2: Subtract 49x from both sides.
49.2x−24.6−49x=49x−8.4−49x
0.2x−24.6=−8.4
Step 3: Add 24.6 to both sides.
0.2x−24.6+24.6=−8.4+24.6
0.2x=16.2
Step 4: Divide both sides by 0.2.
0.2x0.2=16.20.2
