If one of the roots of the equation x² - 4 + k = 0 exceeds the other by 2 , then find the roots and determine the value of k.​

Answers

Answer:3

Step-by-step explanation:

Given

Quadratic equation is [tex]x^2-4+k=0[/tex]

if one root exceeds the other by two

suppose one of the roots is a, then the other is a+2

The Sum of roots is

[tex]=\dfrac{-\text{coefficient of x}}{\text{coefficient of }x^2}[/tex]

[tex]\therefore a+a+2=-\dfrac{-0}{1}\\\\\Rightarrow 2a+2=0\\\Rightarrow a=-1[/tex]

Product of roots

[tex]\Rightarrow (a)(a+2)=\dfrac{k-4}{1}\\\Rightarrow (-1)(1)=k-4\\\Rightarrow k=4-1=3[/tex]

A circular sector has a central angle of π6 radians and a radius of 9 ft.

What is the area of the sector?

Use 3.14 for pi. Round your answer to the nearest tenth.

Enter your answer in the box.

Answers

Answer:

[tex] \approx \: 21.2 \: {ft}^{2} [/tex]

Step-by-step explanation:

[tex]central \: \angle = \frac{\pi ^{c} }{6} = 30 \degree \\ \\ area \: of \: the \: sector = \frac{30 \degree}{360 \degree} \times \pi {(9)}^{2} \\ \\ = \frac{1}{12} \times 3.14 \times 81 \\ \\ = \frac{1}{12} \times 254.34 \\ \\ = 21.195 \: {ft}^{2} \\ \\ \approx \: 21.2 \: {ft}^{2} [/tex]

Answer:

What is the measure of ZKPL?

Answers

Answer:

angle KPL = 70 degree

Step-by-step explanation:

A straight line will equal 180 degrees

To find angle IPN, add angles NPM (60) and IPJ (50) and subtract the number from the straight line (180)

60 + 50 + IPN = 180

110 + IPN = 180

IPN = 70

IPN is a congruent angle to KPL

Congruent means they will equal the same

IPN = KPL

70 = 70

We can check our work by adding NPM (60) and KPL (70) and subtracting the sum from the straight line (180). Our answer should be the same as IPJ (50) as MPL is congruent to IPJ

60 + 70 + MPL = 180

130 + MPL = 180

MPL = 50

Correct

Step-by-step explanation:

Hello There!

First thing we notice is that the y intercept is at (3,0) meaning that they have some sort of fee that has a charge of 3 dollars (represented by the 3)

Because the fee is 3 dollars we can immediately eliminate answers B and C

Now we want to find the charge for each bag of Potpourri (this can be represented by the slope)

Once again we want to choose two points on the line and plug it in into the slope formula

the points are optional but i have chosen the points (1,4.5) and (2,6)

*plug it into the slope formula*

[tex]slope=\frac{6-4.5}{2-1} \\6-4.5=1.5\\2-1=1\\slope =\frac{1.5}{1} or1.5[/tex]

so we can conclude that the charge per bag of potpourri is $1.50 leading us to answer choice A
