PLEASE HELP!! what is the explicit formula for this sequence -7, -4, -1, 2, 5

Mathematics

Answer:

The explicit formula for the given expression is a_n=-10+3n.

Step-by-step explanation:

The given sequence is

-7, -4, -1, 2, 5

The difference between two consecutive terms is same, therefore the given sequence is an arithmetic sequence.

The first term of the given AP is -7 and the common difference is

-4-(-7)=-4+7=3

The explicit formula for an AP is

a_n=a+(n-1)d

Where, a is first term, d is common difference and n is number of terms.

Substitute a=-7 and d=3 in the above equation.

a_n=-7+(n-1)3

a_n=-7+3n-3

a_n=-10+3n

Therefore the explicit formula for the given expression is a_n=-10+3n.

What you could do it is. Start adding numbers and once you get close to
6 numbers See if you are close to 51 and switch around the numbers to make it equal 51 hope this helps

h = -16t^2 + 541? its been forever since i had to do this and frankly I'm completely lost. please if you answer this can you tea
natta225 [31]
A = -16  b = 0  c = 541
Use the quadratic formula which is
x = [-b +- sq root (b^2 -4*a*c)] / 2*a
x = [-0 +-sq root (0 -4*-16*541)] / 2 * -16
x = + - sq root (0 -4*-16*541) / -32
x = + - sq root (34,624) / -32
x = + - 186.075 / -32

x1 = 186.075 / -32 = <span> <span> <span> -5.81484375 </span> </span> </span>
x2 = -186.075 / -32 = <span> <span> <span> 5.81484375 </span> </span> </span>

120 110 A pick-your-own blueberry farm offers 6 pounds of blueberries for $14. Cost (dollars) 100 90 Drag the points to create a
shutvik [7]

The relationship between cost and pounds of blueberries is y = (7/3)x

A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the cost in dollars for x pounds of blueberries.

Since 6 pounds of blueberries cost $14, hence:

m = $14/ 6 pound = $7/3  per pound

Therefore the relationship between cost and pounds of blueberries is y = (7/3)x

Pint 16oz $3.98
LiRa [457]
Okay, so when dealing with unit rates you want to see how much you have of your main measurement. In this case your main measurement is ounces. Since you have 16 and 32 you are going to divide your dollar amount by those and round to the nearest tenth. 
Here are the equations that need to be used. Figure out the answers to them and round. This will give you your answer
3.98/16=
5.98/32=
