-32=4(y-5)-7y solve for y

Mathematics
1 answer:
Savatey [412]3 years ago
8 0

Answer:

y= 4

Step-by-step explanation:

-32= 4(y -5) -7y

Expand:

-32= 4y -20 -7y

Simplify:

-32= -3y -20

+20 on both sides:

20 -32= -3y

Simplify:

-12= -3y

Divide both sides by -3:

y= -12 ÷(-3)

y= 4

Give the expression 4n^2t/2n^t-1, write the expression as a binomial.
lubasha [3.4K]

 <span>binomial </span>is an algebraic expression containing 2 terms. For example, (x + y) is a binomial.

We sometimes need to expand binomials as follows:

(a + b)0 = 1

(a + b)1 = a + b

(a + b)2 = a2 + 2ab + b2

(a + b)3 = a3 + 3a2b + 3ab2 + b3

<span>(a + b)4</span> <span>= a4 + 4a3b</span><span> + 6a2b2 + 4ab3 + b4</span>

<span>(a + b)5</span> <span>= a5 + 5a4b</span> <span>+ 10a3b2</span><span> + 10a2b3 + 5ab4 + b5</span>

Clearly, doing this by direct multiplication gets quite tedious and can be rather difficult for larger powers or more complicated expressions.

Pascal's Triangle

We note that the coefficients (the numbers in front of each term) follow a pattern. [This was noticed long before Pascal, by the Chinese.]

1

1 1

1 2 1

1 3 3 1

1 4 6 4 1

1 5 10 10 5 1

1 6 15 20 15 6 1

You can use this pattern to form the coefficients, rather than multiply everything out as we did above.

The Binomial Theorem

We use the binomial theorem to help us expand binomials to any given power without direct multiplication. As we have seen, multiplication can be time-consuming or even not possible in some cases.

<span>Properties of the Binomial Expansion <span>(a + b)n</span></span><span><span>There are <span>\displaystyle{n}+{1}<span>n+1</span></span> terms.</span><span>The first term is <span>an</span> and the final term is <span>bn</span>.</span></span><span>Progressing from the first term to the last, the exponent of a decreases by <span>\displaystyle{1}1</span> from term to term while the exponent of b increases by <span>\displaystyle{1}1</span>. In addition, the sum of the exponents of a and b in each term is n.</span><span>If the coefficient of each term is multiplied by the exponent of a in that term, and the product is divided by the number of that term, we obtain the coefficient of the next term.</span>

Answer:

6280 mm squared

Step-by-step explanation:

To find the area Of a cylender we multiply pi times r squared times the height, and we can put pi as 3.14

the radius is 10 mm, and the height is 20 mm.

pug it in.

3.14 times 10 squared times 20.

3.14 time 100 time 20

314 times 20

6280 mm squared

docker41 [41]
She would receive $3500 maximum.

Since she has $10,000 in coverage, the entire $4000 loss is covered.  However, the insurance company would only pay her the amount after the deductible has been taken:

4000 - 500 = 3500
