A car moving at a constant speed passed a timing device at t=0. After 6 seconds, the car has
Aliun [14]

The linear function rule is d = 103t

<h3>What Speed is?</h3>

The ratio of the distance travelled to the time taken is known as speed.

The formula for calculating the distance traveled is expressed as:

  • distance = speed * time

  • Speed = distance/time

Speed = 618ft/6s

Speed = 103ft/s

Recall that:

d = st

Substitute s = 103 into the expression to have:

d = 103t

Hence the linear function rule is d = 103t

I need help please help me ‼️‼️‼️‼️‼️

Answer:

A, m < $69.43

Step-by-step explanation:

(Could be wrong, I'm just browsing through brainly and thought it looked easy)

I found the percentage of what they've raised by doing 552.5 * .12 (12 percent of 552.5)

This gave me 66.3

We now need to look for how much they need to raise, so you subtract 552.5 by 66.3 to get 486.2.

You need to find out how much each of the 7 members needs to raise to get 486.2, to do this divide 486.2 by 7 to get 69.45.

Ideally, they would raise just this amount and the correct answer would be an equal sign, but since that isn't an option and if they raised less than 69.45 individually they would fail, raising more than 69.45 would pass their goal. So A, more than 69.45 is the answer.

What is the sum of the given polynomials in standard form? (x2 – 3x) (–2x2 5x – 3).
Rina8888 [55]

Sum of standard form polynomials means adding the terms of same variable. The sum of the given polynomial in standard form is,

-x^2+2x-3

<h3>What is polynomial equation?</h3>

A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.

Here, <em>n</em> is any real number.

In the polynomial equation the the terms are added or subtracted from each other only when the power of the variable is same.

Given information-

The first polynomial equations given in the problem is,

(x^2 - 3x)

The second polynomial equations given in the problem is,

(-2x^2+ 5x - 3).

To find the sum of these two polynomials, add the two terms together as,

(x^2 - 3x)+(-2x^2+ 5x - 3)

Let the result of the sum is f(x). Thus,

f(x)=(x^2 - 3x)+(-2x^2+ 5x - 3)\\f(x)=x^2-3x-2x^2+5x-3

Separate the similar power variable as,

f(x)=(x^2-2x^2)+(-3x+5x)-3\\f(x)=-x^2+2x-3

Thus the sum of the given polynomial in standard form is,

-x^2+2x-3
