Answer:
[tex]m<49/12[/tex]
Step-by-step explanation:
we are given
[tex]y = 3x^2+7x+m[/tex]
To find x-intercept means we have to find zeros
and for finding zeros , we will use quadratic formula
and we have it has two x-intercepts
so, it's discriminant must be greater than 0
so, we will find discriminant
[tex]D = \sqrt{b^2-4ac}[/tex]
now, we can compare with
[tex]y=ax^2+bx+c\\y=3x^2+7x+m[/tex]
and then we can find a , b and c
a = 3, b = 7, c = m
now, we can find D
[tex]D = \sqrt{7^2-4*3*m} \\D=\sqrt{49-12m}[/tex]
It has two x-intercepts
so,
[tex]D = \sqrt{49-12m}>0[/tex]
now, we can solve for m
[tex]49-12m>0\\12m<49\\m<49/12[/tex]

Answer:
It's the bottom one.
Step-by-step explanation:
number one makes no snese because inside of you there is no light
number two, heat and thermal are the same thing
number three, there isn't really potential energy inside you, not in the process of the energy transformation of food.
The bottom one makes the most sense because if you think about all of the steps, it goes chemical (stomach acid), there is also some heat in there, and then mechanical when the food moves from place to place

[tex]x + 29 = 2x + 38[/tex]
[tex]2x + 38 = x + 29[/tex]

(4 - 13)to the 4th power - 6
_____________________ - |-2|
25 ÷ 5
Answer:
4-13 is -9 and -9 to the 4th power is 6561 -6 is 6555
Then you do 25/5 which is 5 so 6555 over 5 is 1311
1311 minus the absolute value of -2 which is 2 so 1311 minus 2 is 1309
Step-by-step explanation:

just did it on there.
The measure of the chord YZ = 7 units.
What is congruent triangle?
The triangle is said to be congruent, if all the three sides are equal and all the angles are equal.
For the given situation,
Two triangles XOW and YOZ are congruent.
Then the sides, WX and YZ are equal.
Thus the measure of the chord, WX = YZ = 7 units.
Hence we can conclude that the measure of the chord YZ = 7 units.

Find the value of W please help due tomorrow
Answer:
59 degrees
Step-by-step explanation:
All the angles of a triangle (when combined) result in 180 degrees. This means that:
Angle 1 + angle 2 + angle 3 = 180 degrees.
We can see here that the shape here is a right triangle (noted by the square in the corner). This means that the angle set with the square is equal to 90. With this, we already have two of our angles! All we need is to set the equation using w, the angle you'll want to find:
31 + 90 + w = 180
w = 59
And there you are! Make sure to practice a few more problems like these to really get the hang of it. Good luck!

Help ASAP please! I need the correct answer.
Answer:
B
Step-by-step explanation:
120 degrees is 1/3 of the circumference of a circle.
So the formula is 2 * pi * r * theta / 360
Arc length = 2* 12 * 3.14 * 120/360
Arc length =25.12 feet
