Which equation represents the polynomial function with zeros −1, 1, and 3 (multiplicity of 2), and a y-intercept of −18? (4 poin
Vlad [161]
Correct Answer:
3rd option is the correct answer

Solution:
The zeros of the polynomial are -1,1 and 3. The multiplicity of 3 is 2. So the polynomial can be expressed as:

y=a (x-3)^{2}(x-1)(x+1)

The y-intercept of the polynomial is -18. This means the polynomial passes through the point (0,-18). Therefore, y must be -18 when x = 0. Using these values of x and y in previous equation we get:

-18=a (0-3)^{2}(0-1)(0+1) \\  \\ &#10;-18=-9a \\  \\ &#10;a=2

The final equation of the polynomial becomes:

y=2 (x-3)^{2}(x-1)(x+1)

Answer:

69.5

Step-by-step explanation:

Formula = 1/2 ( b1 + b2)h

base 1 + base 2 = 220

7645 x 2 = 14000 + 1200 + 80 + 10 = 15290

15290 / 220 =  764.5

H = 69.5

Lets check

1/2(220 x 69.5)

1/2(15290) = 7645

correct

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Which expression is equivalent to (2^5)^-2
irinina [24]

<u><em>1/1024 is the correct answer.</em></u> First you had to apply exponent rule, and it gave us, \frac{1}{(2^5)^2}, or 2^5^*^2. Then you can also refine, and it gave us, 2^10, or \frac{1}{2^10}. And it gave us the answer is 2^1^0=2*2*2*2*2*2*2*2*2*2=1024, or 1/1024 is the correct answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

klemol [59]

the answer is 153.86 ft squared

= the formula for the area of a circle is A=πr2

= area = pi x radius squared

= the radius is 7 feet, square that to get 49

= multiply 49 by pi to get the area: 153.86 square feet

153.86 ft squared
