In an arithmetic sequence, the 10th term is 37, and the 21st term is 4. Find the common difference and the first term

Masja [62]

Answer:

Common difference is 3. And the first term is 64.

Step-by-step explanation:

The differnce between 21 and 10 is 11. So there are 11 unknown numbers in between. And the difference between 37 and 4 is 33. 33/11 is equal to 3. So the pattern is minus three. the first term is 9 terms before 37. 9 times 3 is 27. 37+27 is equal to 64. so the first term is 64

kwasi thought of a number, multiplied it by7/2 and added 16 to the results.if the final answer was 30.what number did he think o

ziro4ka [17]

Answer:

Step-by-step explanation:

represent the number he thought of with x

$\frac{7}{2} x + 16 = 30$

multiply through with the LCM which is 2
$2 \times \frac{7}{2}x + 16 \times 2 = 30 \times 2$
$7x + 32 = 60$
$7x = 60 - 32$
$7x = 28$
$\frac{7x}{7} = \frac{28}{7}$
$x = 4$

The ordered pair (0,0)(1,4)(2,16)(3,36)(4,64). write a rule that represents the function.

gayaneshka [121]

Let x represent first number in pair and y represent second number. We can see that x numbers are increasing by 1 on each next pair. y numbers are square of 0,2,4,6 and 8

Knowing all of that let "n" represent the position of the pair starting from 0!

than we can write that the rule is:
(n,(2n)^2)

How many real number solutions are there to the equation 0=-3x^2 + x -4

natta225 [31]

We have that
the equation
y=-3x² + x -4
the real number solutions are the points x intercept of the graph
are the points when y=0

using a graph tool
see the attached figure

the graph has no point of intersection with the x axis
therefore

the answer is
there are zero real numbers solutions
