Hi there!

Looking at the graph, the first intersection point is clear. The red parabola and  blue line clearing intersect at the point (0, -1).

Find the second intersection point by setting the equations of both graphs equal to each other.

Line: y = 3x - 1

Parabola: y = 4x² - 1

Find another intersection point by setting these two equations equal to each other:

4x² - 1 = 3x - 1

Bring all terms onto one side:

4x² - 3x = 0

Factor out x:

x(4x - 3) = 0

Set 4x - 3 to 0 and solve:

4x - 3 = 0

4x = 3

x = 3/4

Plug in this value of x into an equation to solve for the y-coordinate. Use the linear equation for ease:

y = 3(3/4) - 1

y = 9/4 - 1

y = 5/4

(3/4, 5/4)

One angle of an isosceles triangle is three times the
measure of each of the other two angles. Find the
measures of the angles.

Answers

Answer: largest angle: 108°, smallest angle: 36°

Answer:

36°, 36°, 108°

Step-by-step explanation:

let the 2 congruent base angles of the isosceles triangle be x

Then the vertex angle is 3x

Sum the angles and equate to 180 ( angle sum of triangle )

x + x + 3x = 180

5x = 180 ( divide both sides by 5 )

x = 36 , then

3x = 3 × 36 = 108

The angles are 36°, 36° and 108°

Answers

Answer: 10

Step-by-step explanation:

So since this is all about perimeter you just got to add the values together. So lets use 12 as the denominator for every fraction. 1/4 is equal to 3/12 and 2/3 is equal to 8/12. So in conclusion 3/12 plus 8/12 and 1/12 will equal 1 in total. and then add up all the whole numbers 4 + 2 + 3 + 1 will get you 10. So 10 is your answer.

Let $x$ be the smallest number in the following list, and let $y$ be the second smallest number (that is, the smallest number other than $x$). \[ 5, \qquad -22, \qquad \frac{-4}{7}, \qquad \frac{-3}{-5}, \qquad 3, \qquad \frac{-8}{13} \]Find $\frac{x-y}{y}$. Express your answer as a fraction in simplest form.

Answers

Answer:

139/4

Step-by-step explanation:

and find that\[

\frac{4}{7}\cdot \frac{13}{13} = \frac{4\cdot 13}{91}=\frac{52}{91}, \text{and}

\]\[

\frac{8}{13}\cdot \frac{7}{7} = \frac{8\cdot 7}{91} = \frac{56}{91}.

\]Thus $\frac{8}{13}$ is larger than $\frac{4}{7}$, which tells us that $-\frac{8}{13}$ is smaller than $-\frac{4}{7}$. Thus, $x=-22$, $y=-\frac{8}{13}$, and\begin{align*}

\frac{x-y}{y}&=\frac{-22-\left(-\frac{8}{13}\right)}{-\frac{8}{13}}\\

&=\left(-22\cdot \frac{13}{13}+\left(\frac{8}{13}\right)\right)\cdot \left(-\frac{13}{8}\right)\\

&=\left(\frac{-286+8}{13}\right)\cdot \left(-\frac{13}{8}\right)\\

&=\left(-\frac{278}{13}\right)\cdot \left(-\frac{13}{8}\right)\\

&=\boxed{\frac{139}{4}}.

what are the next two numbers in the sequence 21, 18, 13, 6,

-3,-14

Step-by-step explanation:

21  

18  (-3)

13   (-5)

6    (-7)

-9 .... 6-9 = -3

-11 ... -3 - 11 = -14

Answer: -3, -14

Step-by-step explanation:

You can see that from 21 to 18 the difference is -3

18 to 13 is -5

13-6 is -7

See the pattern yet?   The difference of the numbers are subtracted by 2 again.

-3, -5, -7, then it's -9. then -11

So 6+(-9) = -3

-3+(-11) = -14

round these numbers to the nearest thousand.

Answer:

  a < -5  or  11 < a

Step-by-step explanation:

For there to be two points of intersection, there must be 2 real solutions to ...

  ax +9 = -2x^2 +3x +1

Rewriting to standard form, we have ...

  2x^2 +(a -3)x +8 = 0

The discriminant of this equation is ...

  B^2 -4AC = (a -3)^2 -4(2)(8) = a^2 -6a -55

We want this to be greater than 0. Factoring, we get ...

  (a -11)(a +5) > 0

This will be true for values of a that are less than -5 or greater than 11.

Is the ladder in a safe position for Bryan to use? Show the working on which you base your decision.​

Answers

Answer:

133

Step-by-step explanation:

I am added all the degrees

Given:

Length of ladder = 4.5 meters

Length between ladder and wall = 1.2 meter

To find:

If the angle of the ladder is between 74° - 76°

Steps:

We know,

cos(x) =  [tex]\frac{adjacent}{hypotenuse}[/tex]

Here 'x' is the angle of the ladder. Substituting the values,

[tex]cos(x) = \frac{1.2}{4.5}[/tex]

[tex]x = cos^{-1}(\frac{1.2}{4.5} )[/tex]

[tex]x = cos^{-1}(0.2666)[/tex]

Now we can either use natural cos table or use aa calculator, i am going to use the calculator but if you want to know how to do it with the table, pls comment to this answer.

x = 74.533°

Since x > 74° and x < 76°, it is safe for work

Therefore, the angle is in the safe position for Bryan to use

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given inequality is n<-2 or n≥4

The third number line represents the inequality  n<-2 or n≥4.

The open circle at -2 indicates that n is not included in the solution set, since the inequality is strict.

The closed circle at 4 indicates that n is included in the solution set, since the inequality is not strict.

Hence, n<-2 or n≥4 compound inequality is represented in the third graph.
