Answer:
2187
Step-by-step explanation:
This geometric sequence has a first term of 1 and a common ratio of 3. Its general term can be written as ...
an = a1·r^(n-1)
an = 3^(n-1)
Then the 8th term is ...
a8 = 3^(8-1) = 2187
How do I find the indicated value for this problem?
Answer:

Answer:
0, -3
Step-by-step explanation:
So remember, when they say reflect over the x intercept, they do not mean to reflect the x value, they mean to reflect over the hirzontal line of the graph.(x axis)
This is the same with reflection over the y intrecept. This doesnt mean y is flipped, this means that whatever point or line you have is reflected over the vertical line on the graph(y axis)
So our orginal value is (0, 3). We need to reflect over the x axis, which means that y will now be -3, since that is the opposite of what we can see when we flip the x axis.
The 0 x, of course, stays the same since its 0.
So your answer is (0, -3)
Hope this helps! :)

Answer:
Side Length AB = 22
Side Length CB = 35.21
Side Length = 41.52
Angle A = 58°
Angle B = 90°
Angle C = 32°
Step-by-step explanation:
Side Length CB;Tan(32) = 22 / CB
Tan(32) * CB = 22
CB = 22 / Tan(32)
CB = 35.21
Side Length AC; (Now that we know the Length of AB and BC)22² + 35.21² = AC²
484 + 1239.74 = AC²
1723.74 = AC²
[tex]\sqrt{1723.74}[/tex] = AC
41.52 = AC
Angle A (Since we know Angle B and Angle C)Angle A + Angle B + Angle C = 180°
Angle A + 32° + 90° = 180
Angle A + 122 = 180
Angle A = 180 - 122
Angle A = 58°
Hope this helps!
Answer:
Sine Rule will apply here too
22/Sin32° = AC/sin90
AC = 22sin90/sin32
AC=41.52(To the nearest 100th)
Angles in a triangle =180
Angle A = 180 - 90 - 32
Angel A = 58°
BC/Sin58 = 22/sin32
BC = 22sin58/sin32
BC=35.21 (Nearest 100th).
Have a great day!

At age 20, William starts a career with a salary of $40,000 and a promise of a yearly raise of 2%. Approximately how much money will he make over 10 years?
Answer:
8759.78
Step-by-step explanation:
cause by the end of the 10 years he would have 48759.77 minus that by 40,000 you would get 8759.78
Approximately how much money will he make over 10 years is $8,759.78.
Using this formula
Amount=[Principal(1+rate)^t]- Principal
Where:
Principal=$40,000
Rate=2%
Time=10 years
Let plug in the formula
Amount=[$40,000×(1+0.02)^10]-$40,000
Amount=[$40,000×(1.02)^10]-$40,000
Amount=$48.759.776-$40,000
Amount=$8,759.776
Amount=$8,759.78 (Approximately)
Inconclusion approximately how much money will he make over 10 years is $8,759.78.

a circle is drawn in a coordinate plane centered at (8,15) and a radius of 3 units.
Answer:
(x - 8)² + (y - 15)² = 9
Step-by-step explanation:
Assuming you want the equation.
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k ) = (8, 15 ) and r = 3 , then
(x - 8)² + (y - 15)² = 9

Hope This Helps You ❤️Solve the equation x2 – 10x – 8= 0 to the nearest tenth.
Answer:
x = -0.8 and 10.8
Step-by-step explanation:
Given the equation x2 – 10x – 8= 0
Using the general formula
x = -b±√b²-4ac/2a
x = -(-10)±√(-10)²-4(1)(-8)/2(1)
x = 10±√100+32/2
x =10±√132/2
x = 10±11.489/2
x = 10-11.489/2 and 10+11.489/2
x = -1.489/2 and 21.489/2
x = -0.8 and 10.8
13. A square based cuboid has a width of 4cm. If the volume of the cuboid is 400 cubic
centimeters, what is the surface area of the cuboid?
Answer:
216 cm²
Step-by-step explanation:
Applying,
V = lwh..................... Equation 1
Where V = volume of the cubiod, l = length of the base, width of the base, h = heigth of the cubiod.
From the question,
Since the base of the cubiod is squared,
Therefore,
w = l = 4 cm, V = 400 cm³
Substitute these values into equation 1
400 = 4×4×h
h = 400/(4×4)
h = 25 cm
A = lw+lh+wh.................. Equation 1
Where A = surface area of the cuboid.
Given: l = 4 cm. w = 4 cm, h = 25 cm
Substitute these values into equation 1
A = (4×4)+(4×25)+(4×25)
A = 16+100+100
A = 216 cm²
