Answer: The function could be y= - 3 cos x

Solution:

One x-intercept is (pi/2,0): We can use a trigonometric function like cosine that has x-intercept (pi/2,0).

The domain of the cosine function is the set of all real numbers.

The maximum value is 3, then the amplitude must be 3: y = 3 cos x

The y-intercept is (0,-3) then it is the functio y = 3 cos x, reflected around the x-axis: y = - 3 cos x

-8x+5y= -40

First, add 8x to both sides

5y= 8x-40

Now divide both sides by 5

y= 8/5x-8

Answer:

A. 3.2% faster

B. 3.3% slower

C. 103.3%

Step-by-step explanation:

In order to find this out, we need to take the differences and divide them by the comparative time. So, in the first one, we take the difference (.32) and divide it by Hines time.

.32/9.63 = 3.2%

In the second, we take the difference and divide by Bolt's time.

.32/9.95 = 3.3%

And finally, in the last one, we take Hines' time and divide by Bolt's.

9.95/9.63 = 103.3%

write the equation for a polynomial of least degree with integer coefficients given the following zeros: -2, -6, -10i. leave you
lorasvet [3.4K]

The equation of the polynomial in factored form is (x+2)(x+6)(x-10) = 0

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

A polynomial is an algebraic equation with at least the power of its variable 3.

Analysis:

if -2, -6, -10i are the zeroes of the polynomial, it means x = -2, x = -6, x = -10i

if x = -2, (x+2) is a factor, (x+6) is a factor.

convert x = -10i to a real number,

i = \sqrt{-1}

-10\sqrt{-1} = 10\sqrt{- -1} = 10\sqrt{1} = 10

x = 10, so (x-10) is a factor.

Therefore equation of the polynomial in factored form is (x+2)(x+6)(x-10) = 0
