Identify a point and two x intercepts to write the x-intercept form equation of each parabola.

Answers

Answer:   y = 2(x-5)(x-7)

x intercepts are 5 and 7

The third point I used was (6,-2); however, you can use any other point you want as long as it's not one of the x intercepts mentioned.

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

Explanation:

The x intercepts are 5 and 7, where the parabola crosses the x axis. Because of these roots, the two factors are x-5 and x-7.

We can think of the root x = 5 turning into x-5 = 0 after subtracting 5 from both sides. The same goes for x = 7 turning into x-7 = 0.

Put together, the two factors lead to (x-5)(x-7) and we get the equation y = (x-5)(x-7). Plugging either x = 5 or x = 7 into this equation produces y = 0.

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

Notice that plugging in x = 6 leads to...

y = (x-5)(x-7)

y = (6-5)(6-7)

y = (1)(-1)

y = -1

However, the graph shows that x = 6 should lead to y = -2 instead. To fix this, we can stick a 2 out front like so

y = 2(x-5)(x-7)

y = 2(6-5)(6-7)

y = 2(1)(-1)

y = -2

The error has been fixed. As you can see, we need this third point to help nail down the parabolic equation. You can pick any other x value you want as long as it's not 5 or 7.

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

Let's try another x value. Let's say we pick x = 8

y = 2(x-5)(x-7)

y = 2(8-5)(8-7)

y = 2(3)(1)

y = 6

We see that x = 8 leads to y = 6. This matches what the graph shows that (8,6) is a point on the parabola. I'll let you try other x values.

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

In short, we used the roots 5 and 7 to generate the partial factorization (x-5)(x-7). Then we used a third point (6,-2) to help determine the coefficient out front which was 2.

So after using that point, we go from y = (x-5)(x-7) to y = 2(x-5)(x-7) which is the final answer. This is considered x-intercept form because we can quickly read off the x intercepts from this equation.

A lava lamp is an example of which type of heat transfer?
A. Solar Energy
B. Radiation
C. Conduction
D. Convection

Answers

Answer:

C

Brainlest

Step-by-step explanation:

✨D. ✨



We did this in 6th grade. The energy changes the density of the wax as it heats up; the molecules expand out from each other, causing the wax to become liquid-like blobs. By convection, the heat moves the liquid-like wax blobs up. By radiation, the heat energy moves from the glass and out in electromagnetic waves. Lava Lamp Model of Convection As a substance gains heat energy (in the case of the lava lamp, heat is transferred from the hot light bulb to the lava), it becomes less dense than the surrounding liquid ), causing the substance to rise.

Additionally, what type of energy does a lava lamp use? Energy starts from the electricity flow, when you plug in a lava lamp. The energy becomes thermal energy to produce heat from the light at the bottom of the lava lamp. The thermal energy from the light is transferred to the lava and uses the thermal energy to warm up the lava lamp.

Conduction is the transfer of heat through direct contact (in this case, metal coil contact with the "lava" at the bottom of the lava lamp). Convection is the transfer of heat through movement such those in a flowing medium (such as liquids or gases, or in this case as the "lava" rises in a lava lamp).

How convection works in the mantle?

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. This hot added material cools down by conduction and convection of heat.

Which is the correct translation of the sentence into an equation?

Four less than a number is 12.

A: n-12=4
B: n-4=12
C: 4-n=12
D: 12-n=4

Answers

Answer:

B

Step-by-step explanation:

n is a number. 4 less then that number translates to n-4, so the answer is B:

n-4=12

Hope that helps! :)

Answer:

C: n-4= 12

Step-by-step explanation:

To understand why this answer is correct, lets break down the sentence.

Four less = [tex]4-[/tex]The part "than a number" can be represented as n as in math, unknown numbers are variables in order to isolate them to and figure out their values. "is 12" will represent the sum of the equation as the sentence is clarifying that that 4 minus the variable n is equal to 12.

Revised Answer: n-4=12 is actually the answer as n can be any quantity, and n -4 =12 literally means n + (-4) = 12.

On a certain hot​ summer's day, 294 people used the public swimming pool. The daily prices are for $1.75 children and for $2.25 adults. The receipts for admission totaled $635.50 How many children and how many adults swam at the public pool that​ day?

Answers

Answer:

a = 242  adult and  c = 52 children

Step-by-step explanation:

Solving as a system of equations.

a = adult

c = children

The adult and the children equal 294 people

  a + c = 294

adult cost is 2.25 per adult

Total amount of adult is 2.25a because the number of adult are not given.

children cost is 1.75 per children

Total  amount children is 1.75c because the number of children  are not given

Total receipts $635.50.

a + c = 294                         multiply by -1.75           -1.75a - 1.75c = - 514.50

2.25a + 1.75c = 635.50     does not change           2.25a + 1.75c =  635.50

Add these equations together

-1.75a - 1.75c = - 514.50

2.25a + 1.75c =  635.50    

.50a              =   121.00

   a = 121.00/.50a

   a = 242  adult

a + c = 294

242 + c = 294

         c = 294 - 242

          c = 52 children

Check:    $2.25(242) + $1.75( 52) = $635 .50

              $544.50 + $91.00 =  $635.50

                   $635.50 = $635.50

Both triangles are clearly congruent, both having the same type of angles as well as angle LKJ and angle VKW having the same angle measure, 21 degrees. Lastly, if you were to take out segment JL and WV, the triangles would fold the same. All of this leads to segment XV being the same as segment KL which leads it to be 24 mm.
