What is the 50th term of the sequence that begins -4, 2, 8, 14....?

vagabundo [1.1K]

Answer:

$a_{50}=290$

Step-by-step explanation:

Notice that we are in the presence of an arithmetic sequence (there is a common difference of 6 between a term and the next). So thisis an arithmetic sequence with first term $a_1=-4$ . and common difference "<em>d</em>" = 6.

Recall now the formula for the nth term ( $a_n$ ) of an arithmetic sequence:

$a_n=a_1+(n-1)\,d$

Then, using our values in the formula, we get:

$a_n=a_1+(n-1)\,d\\a_{50}=-4+(50-1)\,6\\a_{50}=-4+(49)\,6\\a_{50}=290$

A foot ball field measures 100m by 72m. A school marks a football field similar in shape to a fullsize football field but only 3

Anna35 [415]

Answer: 21.6 m

Step-by-step explanation:

Given

A football field measures $100\ m\times 72\ m$

If a football field similar in shape to a full size has a length $l=30\ m$

The ratio of the length of the original to the small field is the same

Assume the width of the small field is w

$\therefore \dfrac{100}{30}=\dfrac{72}{w}\\\\\Rightarrow w=30\times \dfrac{72}{100}\\\\\Rightarrow w=21.6\ m$

Thus, the width of the field is 21.6 m

A coordinate plane with a line passing through (0, negative 3), (2, 0), and (4, 3). Which equation represents the graphed functi

Talja [164]

Answer:

$y=\frac{3}{2}x-3$

Step-by-step explanation:

we have the points

(0,-3),(2,0) and (4,3)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we take

(0,-3),(2,0)

substitute the values in the formula

$m=\frac{0+3}{2-0}$

$m=\frac{3}{2}$

step 2

Find the equation of the line in slope intercept form

$y=mx+b$

we have

$m=\frac{3}{2}$

$b=-3$ -----> the point (0,-3) is the y-intercept

substitute

$y=\frac{3}{2}x-3$
