Find the zeros of 7=x^2-8x-3 by completing the square
enot [183]

Using the completing the square method, for the equation, we have the zeros as <u>x = √26 + 4 and x = 4 - √26</u>

<h3>How can the zeros be found using completing the square method?</h3>

The given equation is presented as follows

7 = \mathbf{ {x}^{2}  - 8x - 3}

Which, by completing the square, gives;

{x}^{2}  - 8x - 3 - 7 = 0

{x}^{2}  - 8x - 10 = 0

{x}^{2}  - 8x  +   {\left(\frac{8}{2} \right) }^{2} - 10  -  {\left(\frac{8}{2} \right) }^{2} = 0

\mathbf{{(x - 4)}^{2} }   =26

The zeros of the equation;

7 =  {x}^{2}  - 8x - 3

are;

\underline{x = \pm \sqrt{26}  + 4}

which of the following is the correct graph of the compound inequality 4p + 1&gt; -7 and 6p + 3 &lt; 33 ?
PtichkaEL [24]
<h3>Answer:  Choice C</h3>

============================================================

Explanation:

Let's solve the first inequality for p

4p+1 > -7

4p > -7-1

4p > -8

p > -8/4

p > -2

And we'll do the same for the second inequality as well

6p+3 < 33

6p < 33-3

6p < 30

p < 30/6

p < 5

----------------------

We've found that p > -2 and p < 5

This must mean -2 < p < 5

The graph of which consists of open holes at -2 and 5 on the number line, then we shade in between those open holes. The open holes are to indicate "do not include the endpoint as part of the shaded solution set".

We can say that p is between -2 and 5, excluding both endpoints.

So that's why graph C is the final answer.

One more repair is needed to get the ferris wheel up and running! This one will require a cable to connect chair L to the ground
Elodia [21]

Answer:

<h2>15°</h2>

Step-by-step explanation:

We know that the central angle of a circle is 360°.

In this case, we have the circle divided into 12 equal parts, so each angle would be also the 12th part of 360°.

\theta = \frac{360\° }{12}= 30\°

Each circular sector has an angle of 30°, and each arc is equal to 30°.

Now, notice that tha angle formed by the two blue cables is an external angle formed by two secants, that means we can use the following relation

\alpha = \frac{1}{2}(60\° - 30\°)

Where \alpha is the angle formed by the two blue cables.

\alpha = \frac{1}{2}(30\°)=15\°

Therefore, the angle measures 15°.
