3. A car starts from rest and accelerates uniformly over a time of 6.21 seconds

Mathematics

5 0

We have,

t = 6.21 s

s = 111 m

u = 0 m/s

To determine: "a" of the particle.

We know,

s = ut + ½ at²

⇒ s = ½ at²

⇒ a = 2s/t²

⇒ a = [2(111 m)]/(6.21 s)²

⇒ a = (222 m)/(38.5641 s²)

⇒ a ≈ 5.75 m/s²

If the factors of quadratic function f are (x-7) and (x+3) what are the zeros of function g?
Thepotemich [5.8K]

If the factors of quadratic function f are (x – 7) and (x + 3). The solution of the quadratic function f will be the negative 3 and 7.

<h3>What is a factorization?</h3>

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

If the factors of quadratic function f are (x – 7) and (x + 3).

Then the zeroes of function f will be

(x – 7)(x + 3) = 0

                x = 7, -3

Then the solution of the quadratic function f will be the negative 3 and 7.

More about the factorization link is given below.

Find the length of the third side to the nearest tenth
Aliun [14]

Answer:

9.2

Step-by-step explanation:

to find the third side you need to use the Pythagorean Theorem, which is a²+b²=c². In this case, 6²+7²=c², or 36+49=c². c²=85, so do the square root of 85 to get the length of c, which is 9.2.

A new business center in town was built in a shape of a regular nonagon. Each side is 160 feet long which is the area occupied b
charle [14.2K]

Answer:

158,254.08 ft²

Step-by-step explanation:

A nonagon is a polygon with 9 sides and 9 angles.  A regular nonagon has all equal sides and all equal angles.  In order to find the area of a nonagon, you can use the formula:

A = \frac{9}{4}a^{2}cot(\frac{180}{9}) where 'a' represents the length of one side

Calculating the known measurements ahead of time, we get a condensed, or simplified formula:

A = 6.1818 x a²

Using the side length of 160 ft:

A = 6.1818 x 160² = 158,254.08 ft²
