Can the quadratic polynomial x2+kx+k have equal zeroes for some odd integer k>1

1 answer:

7 0

No.
The only value that can be put in K that would have the same zeros would be 4 but 4 is not an odd integer. If there was an odd integer that the sum and product would be the same then it would lie on the x-axis. but only 4 fits the criteria.

Please help me find the total area of the composite figure below (geometry)

Akimi4 [234]

Answer:

lw + $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$ ⇒ Answer D is correct

Step-by-step explanation:

First, let us find the area of the semi-circle.

Area = $\frac{1}{2}$ × π × r²

Given that,

diameter of the semi-circle is ⇒ l

∴ radius ⇒ l / 2

Let us find it now.

Area = $\frac{1}{2}$ × π × r²

Area = $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$

Secondly, let us find the area of the rectangle.

Area = length × width

Given that,

length ⇒ l

width ⇒ w

Let us find it now.

Area = length × width

Area = l ×w

Area = lw

And now let us find the total area.

Total area = Area of the rectangle + Area of the semi - circle

Tota area = lw + $\frac{1}{2}$ × π × $(\frac{l}{2} )^{2}$

You are given a formula and told that it is a formula for the area of a quadrilateral. can you tell whether it is the formula fo

AleksAgata [21]

The area for a rectangle is length × width.
The area for a parallelogram is base × height.
The area for a trapezoid is height (base 1 + base 2) ÷ 2. The area for a rhombus is base × height.

Hope this helps^^ :)

Find the measure of angle CHF.

swat32

9514 1404 393

Answer:

115°

Step-by-step explanation:

Angle CHF has a measure equal to the average of the arcs the chords intercept.

angle CHF = (arc CDF +arc AB)/2 = (190° +40°)/2

angle CHF = 115°
