352,345,338,... Find the 43rd term
Airida [17]

Step-by-step explanation:

it seems we are dealing with subtraction, as the differences between the 1st and second, and between the 2nd and 3rd numbers are equal : -7

so, we can assume that the sequence is created by always subtracting 7.

a1 = 352

a2 = a1 - 7 = 352 - 7 = 345

a3 = a2 - 7 = a1 - 7 - 7 = 352 - 7 - 7 = 338

an = an-1 - 7 = a1 - 7(n-1) = 352 - 7(n-1)

a43 = 352 - 7(43-1) = 352 - 7×42 = 352 - 294 = 58

A drama teacher has a budget of $120 to spend on materials to create costumes for a play. She can buy 1 square yard of white mat
Neporo4naja [7]

Inequalities are used to relate unequal expressions

The greatest whole number of square yards the teacher can buy is 4

The inequality is given as:

8x + 10y \le 120

When the <em>number of square yards </em>of the white fabrics is 10.

It means that: x = 10

So, we have:

8 \times 10 + 10y \le 120

80 + 10y \le 120

Collect like terms

10y \le 120 - 80

10y \le 40

Divide both sides by 10

y \le 4

The above inequality means that:

The greatest whole number of square yards the teacher can buy is 4

What are the solution of the equation x^2- 4x -32 = 0 ?show your work and justify each step.
soldier1979 [14.2K]
X^2-4x-32=0

(x+a)(x+b)

x^2-(a+b)x+ab

a+b=4
ab=-32

a=-b+4
(-b+4)b=-32

-b^2+4b=-32
b^2-4b-32=0
b=8,-4

If b=8, a=-4
If b=-4, a= 8

Plug in a and b to (x+a)(x+b)
x= -4, 8

What are the differences among an experiment, a study, and a survey?
Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

One

Randomization not only occurs, but the person conducting the experiment has no idea who is receiving what. If there are two groups, there are members in each group that receive a drug and others who do not.

Two

poses no interference on the subjects. The information is obtained. It is pretty objective. When the survey is complete so is the person interviewed by those conducting the survey.

Three

Treatment is imposed at least on 1/2 the participants.
