What is the root when talking about a quadratic equation
The root is the x intercepts or the zeros of the problem
If I were to graph
(x-5)(x+4)=0
We need a number for x which makes this equation 0
The numbers are 5 or -4
These are the x intercepts of the parabola or roots
Answer:
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Of the fifth graders in oak elementary, 6/8 are in band. What fraction of the fifth graders are not in band?
Answer:
2/8 of the fifth graders are not in band
Step-by-step explanation:
To find how many fifth graders are not in band, subtract the # of fifth graders in band. Your difference is the amount of fifth graders that are not in band. To check your answer add 2/8 + 6/8 which should be equal to 8/8 or a whole ( 1 ).
2x+7<13 please help
Answer:
x<3
Step-by-step explanation:
let us solve this inequality step-by-step
2x+7<13
step 1: subtract 7 from both sides
2x+7−7<13−7
2x<6
step 2: divide both sides by 2
2x/2<6/2
step 3: simplify
x<3
good luck :)

You have tiles numbered 1-9 in a bag. What is the probability of drawing a multiple of 3,putting it aside, and then drawing the number 5
Answer:
1/18
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
Multiples of 3 between 1 - 9 = 3,6,9
Probability of picking a multiple of 9 = total multiples of 9 in the bag / total tiles in the bag
3/9
To transform to the simplest form. divide both the numerator and the denominator by 3
1/3
After picking the multiples of 3, the tiles are not replaced, tiles in the bag would now be 6
Probability of picking 5 = 1/6
1/6 x 1/3 = 1/18
Solve for X I need help please

Answer:
Question 5: The missing term her is r²
Question 6: The missing term here is 3.
Step-by-step explanation:
Question 5:
Let's write the equation and then solve it for the missing term. We will call this term x.
[tex](6r^{4}+4r)+(x-2r^{4}+3r)=4r^{4}+r^{2}+7r[/tex]
First, we simplify the letf term adding the similar terms.
[tex]x+4r^{4}+7r=4r^{4}+r^{2}+7r[/tex]
Now, we substract 4r⁴ and 7r in both sides.
[tex]x=r^{2}[/tex]
Therefore, the missing term her is r²
Question 6:
Here, we will call the missing term y. Now, let's solve it for y.
[tex](y-8x-x^{2})-(4x^{2}-7+6x)=-5x^{2}-14x+10[/tex]
Let's first distribute the minus sign into the parentehsis.
[tex]y-8x-x^{2}-4x^{2}+7-6x=-5x^{2}-14x+10[/tex]
Now simplify the left side by adding similar terms.
[tex]y-14x-5x^{2}+7=-5x^{2}-14x+10[/tex]
Now, let's add 14x and 5x² on both sides, then subtract 7 on both sides.
[tex]y=10-7[/tex]
[tex]y=3[/tex]
Therefore, the missing term here is 3.
I hope it helps you!
Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 42 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H0: p = 72% and Ha: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, the estimated P-value is 0.06. Using = 0.10, what conclusion should Devon reach?

Me ajudemmm é pra hoje!!! Escreva como produto entre um número natural e uma potência de base 10. a) 300 b)4.000 c)50 000 d)700.000
Responder:
3 * 10²
4 * 10³
5 * 10⁴
7 * 10 ^ 5
Explicação passo a passo:
Expressando o seguinte como um produto de um número natural e uma potência base de 10.
Lembrar :
10 = 10¹
100 = 10 * 10 = 10²
1000 = 10 * 10 * 10 = 10³
Portanto,
300 = 3 * 100 = 3 * (10 * 10) = 3 * 10²
4000 = 4 * 1000 = 4 * (10 * 10 * 10) = 4 * 10³
50000 = 5 * 10000 = 5 * (10 * 10 * 10 * 10) = 5 * 10⁴
700000 = 7 * 100000 = 7 * (10 * 10 * 10 * 10 * 10) = 7 * 10 ^ 5

Is water wet?? Explain
Answer:
WATER IS not wet
Step-by-step explanation:
Water is NOT wet by itself, however it makes other materials wet when it sticks to the surface of them.
Answer:
Water isn't wet by itself, but it makes other materials wet when it sticks to the surface of them. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material.

62.000124 in. cubed
Step-by-step explanation:
cm to inches: 0.3937007874 to 1
the side edges are 3.937007874
Since it's a square pryramid, all of the side lengths are equal. 3.937007874^2 is 15.500031.
The formula for a pyramid: base*height/3
15.500031*12/3 = 62.000124 in. cubed
