Use the quadratic formula to solve 2y2 – 10y + 8 = 0.

Answers

Answer 1

Answer: $2y^2-10y + 8 = 0\n \na=2, \ b=-10 , \ c= 8 \n \n\Delta =b^2-4ac = (-10)^2 -4\cdot2\cdot 8 = 100-64=36 \n \nx_(1)=(-b-√(\Delta) )/(2a)=(10-√(36))/(2\cdot 2 )=( 10-6)/(4)=(4)/(4)= 1\n \nx_(2)=(-b+√(\Delta) )/(2a)=(10+√(36))/(2\cdot 2 )=( 10+6)/(4)=(16)/(4)= 4$

What is zero of a function?

Zero of a function is defined as the roots of the function for which the value of the function will be 0 at those points.

If p is the zero of the function f(x)=0 then f(p)=0.

We have,

f(x) = (x-1)² (x+3)³ (x+1)

Now,

The zero is located at x=1 and has a multiplicity of 2.

Because the number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity.

The zero is located at x = - 3 and has a multiplicity of 3. The graph of the function will touch, but not cross, the x-axis at the x - the value of 1.

The complete question is given below:-

Consider polynomial function f f(x)=(x-1)^2(x+3)^3(x+1)

use the equation to complete each statement about this function

The zero located and x=1 has a multiplicity of __ and the zero located at x=-3 has a multiplicity of __. The graph of the function will touch, but not cross, the x-axis at the x-value of __.

Jen bought some bagels the ratio of the numbers of sesame beagles to the number of plain bagels the she bought is 1:3 find the decimal equivalent of the prrcent of the bagels that are plain

Answers

If the number of sesame to plain bagels is 1:3, that means that for every 3 plain bagels, there is 1 sesame bagel. So if there were 4 bagels total, with 3 being plain and 1 being sesame, then the fraction of the total amount of bagels represented by the amount of plain bagels there are would be 3/4.
3/4 written as a decimal would be 0.75, or 75%.

Please help me! I’m so confused!! I will give BRAINLIEST :) A coat hanger is in the shape of isosceles triangle ABC shown in the figure. Sides AB and BC are congruent.

If angle BAC = 22 degrees the angle ABC = ?

Answers

Answer:

136 degrees

Step-by-step explanation:

if BAC is 22 degrees, than BCA is also 22 degrees. together that's 44 degrees. triangles are 180 degrees in total so 180 - 44 is 136

Answer:

Angle ABC is equal to 136 degrees.

Step-by-step explanation:

Since sides AB and BC are congruent (meaning they are equal to each other), they will have the same angle measurement. So, angle BAC and angle BCA will both have a measure of 22 degrees.

Triangles always add up to 180 degrees, so add 22 and 22 together, and subtract from 180. This leaves you with 136 degrees for angle ABC.

136 + 22 + 22 = 180, so this works!
