Hint :-
Break the given sequence into two parts .Notice the terms at gap of one term beginning from the first term .They are like [tex]\dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] . Next term is obtained by multiplying half to the previous term . Notice the terms beginning from 2nd term , [tex]4,7,10,13[/tex] . Next term is obtained by adding 3 to the previous term .Solution :-
We need to find out the sum of 50 terms of the given sequence . After splitting the given sequence ,
[tex]\implies S_1 = \dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] .
We can see that this is in Geometric Progression where 1/2 is the common ratio . Calculating the sum of 25 terms , we have ,
[tex]\implies S_1 = a\dfrac{1-r^n}{1-r} \\\\\implies S_1 = \dfrac{1}{2}\left[ \dfrac{1-\bigg(\dfrac{1}{2}\bigg)^{25}}{1-\dfrac{1}{2}}\right] [/tex]
Notice the term [tex]\dfrac{1}{2^{25}}[/tex] will be too small , so we can neglect it and take its approximation as 0 .
[tex]\implies S_1\approx \cancel{ \dfrac{1}{2} } \left[ \dfrac{1-0}{\cancel{\dfrac{1}{2} }}\right] [/tex]
[tex]\\\implies \boxed{ S_1 \approx 1 }[/tex]
[tex]\rule{200}2[/tex]
Now the second sequence is in Arithmetic Progression , with common difference = 3 .
[tex]\implies S_2=\dfrac{n}{2}[2a + (n-1)d] [/tex]
Substitute ,
[tex]\implies S_2=\dfrac{25}{2}[2(4) + (25-1)3] =\boxed{ 908} [/tex]
Hence sum = 908 + 1 = 909

what the example of constant and variable?
Answer:
A constant is a defined value often portrayed as a number.
A variable is a value that can change and is often represented as a letter.
Step-by-step explanation:
For example:
In the equation ? = 10x + 3y + 17
10, 3, and 17 are all constants.
X and Y are both variables.
To reiterate, constants are known values that can NOT change while variables are unknown values that can change!

irreducible fraction of -30/40
Answer:
-3/4
Step-by-step explanation:
An irreducible fraction (or fraction in lowest terms, simplest form or reduced fraction) is a fraction in which the numerator and denominator are integers that have no other common divisors than 1 (and −1, when negative numbers are considered).
so
-30/40 =
-3/4

Answer:
y =90° x =70°
Step-by-step explanation:
Answer:
x = 70° , opposite angles of the same line with angle 70.
sum of interior angles of trapezium is 360°.
y + 70° + 90° + 110° = 360°
y = 90°

Fit Data to a line
When using empirical data ( data and information collected by scientists in an experiment ), sometimes, that data will not form a perfect line on a graph. when this happens, the line that is created using a linear regression is known as the " line of best fit " the following speed data was collected from a car moving with a constant acceleration.
1 - what is the line of best fit for this data? perform a linear regression on this table to find the equation .
2 - based on your equation, what was the car's approximate initial velocity (at time = 0) ?
3 - if the car continued at the same acceleration (meaning the slope of the line does not change), how fast would it be going in 15 seconds ?
Using a linear regression calculator, the best fit line, initial velocity and the velocity of the car after 15 seconds is :
y = 3.64x + 5.7 Initial Velocity = 5.7 m/s Velocity after 15 seconds = 60.3 m/sUsing technology, the linear regression equation obtained by fitting the data is :
y = 3.64x + 5.7x = times(seconds) ; y = velocity(m/s)The approximate velocity at time = 0 ; x = 0 :
y = 3.64(0) + 5.7
y = 0 + 5.7
y = 5.7 m/s
3.) Velocity after 15 seconds :
At time, x = 15 seconds
y = 3.64(15) + 5.7
y = 60.3 m/s
Therefore, the velocity of the car after 15 seconds is 60.3 m/s

If B = -p + 10p2 and C = 2p + 7, find an expression that equals B + 3C in
standard form.
Answer:
10p^2 + 5p + 42 = b+3c
Step-by-step explanation:
b = -p + 10p^2
c = 2p + 7
b + 3c = 5p + 10p^2+ 42
PLEASE SHOW STEPS // -5 (2b + 7) + b < -b - 11
Answer:
b < -11
Step-by-step explanation:
-5 X 2b = -10b + -35 +b
-10b + 35 + b < -b -11
-b -b
cancel out the b
-10b + 35 < -11
-35 < - 35
-10b <-11
-10 < -10
b < -11 and that's your answer
