Add.Your answer should be an expanded polynomial in standard form.
(-t^4 – 5t^3– 10t^2) + (9t^3+ 3t^2– 1) =

Answers

According to given question, The simplified polynomial in standard form is: $-t^4 + 4t^3 - 7t^2 - 1$

To add the two polynomials and simplify, we'll combine like terms:

$(-t^4 - 5t^3 - 10t^2) + (9t^3 + 3t^2 - 1)$

In mathematics, a polynomial is an algebraic expression consisting of variables (also known as indeterminates) and coefficients, combined using addition, subtraction, and multiplication operations. The variables are raised to non-negative integer powers, and the coefficients are constants that multiply the variables. The term "polynomial" comes from the Latin words "poly" (meaning "many") and "nomial" (meaning "term").

Step 1: Combine the terms with $t^4 and t^3:$

$(-t^4) + (9t^3 - 5t^3) - 10t^2 + 3t^2 - 1$

Step 2: Combine the $t^3$ terms and the $t^2$ terms:

$(-t^4) + (4t^3) - 7t^2 - 1$

So the simplified polynomial in standard form is:

$-t^4 + 4t^3 - 7t^2 - 1$

Answer:

$- {t}^(4) + 4 {t}^(3) - 7 {t}^(2) - 1$

Step-by-step explanation:

$( - {t}^(4) - 5 {t}^(3) - 10 {t}^(2) ) + (9 {t}^(3) + 3 {t}^(2) - 1) \n = - {t}^(4) - 5 {t}^(3) - 10 {t}^(2) + 9 {t}^(3) + 3 {t}^(2) - 1 \n = - {t}^(4) + 9 {t}^(3)- 5 {t}^(3) + 3 {t}^(2) - 10{t}^(2) - 1 \n = - {t}^(4) + 4 {t}^(3) - 7 {t}^(2) - 1$

16.437 rounded to the neatest tenth is 16.4 true or false

Answers

Answer=True

When rounding 16.437 to the nearest tenth, we need to look to the hundreds place.

16.437

The number 3 is in the hundreds place

The rules of rounding are:

If the number is 5 or greater, then you round up.

If the number is 4 or less, Then you round down.

Since 3 is less than 4, we would round down. So...

16.437 becomes 16.4

It is true because after the decimal the digit is in the tenths catagory then hundreths and thousandths etc. That is why it is tenths.
