Answer:

255+35-75

Step-by-step explanation:

Since we are trying to find the account balance, we consider anything in or going to the account to be positive.

255 is positive since it is in the account

35 is positive since it is going into the account

75 is negative because it is going out of the account

so the final expression to express the amount is the checking account would be 255+35-75

A quadradic polynomial has a degree of 2 true or false

nataly862011 [7]

Answer: True

Step-by-step explanation:

We know that the quadratics polynomials have this form:

$f(x)=ax^2+bx+c$

You need to remember that the degree of a polynomial is given by its highest exponent.

You can observe in the quadratic polynomial $f(x)=ax^2+bx+c$ that the highest exponent is "2", which is the exponent of the term $ax^2$

Therefore, since the highest exponent is "2", you should conclude that the degree of the polynomial is 2.

Then, you can say that a quadradic polynomial has degree 2.

The function h=-16t^2 +1700 gives you the height h, of an object in feet, at t seconds. How long will it take the object to hit

garik1379 [7]

Answer:

The object will hit the ground after 10.308 seconds.

Step-by-step explanation:

h(t) = -16t² + 1700

If you graphed this function, the object would be shown hitting the ground when it crosses the x-axis, in other words, when h = 0. So, to find the answer, just set h(t) equal to 0 and solve.

-16t² + 1700 = 0 Plug this into a calculator if you have one.

t = -10.308 and t = 10.308

Since time can't be negative, your answer will be the positive value, 10.308.
