Answer:
See below
Step-by-step explanation:
Basically, when you have a product to two factors set equal to 0, you can use the Zero Product Property and make two separate equations, both set equal to 0, to find the roots for each factor:
[tex]2x+10=0\\2x=-10\\x=-5[/tex]
[tex]x-7=0\\x=7[/tex]
Notice that by plugging these roots back into the equation, either factor will be 0, making the whole expression 0:
[tex](2x+10)(x-7)=0\\(2(7)+10)(7-7)=0\\(24)(0)=0\\0=0[/tex]
[tex](2x+10)(x-7)=0\\(2(-5)+10)(-5-7)=0\\(0)(-12)=0\\0=0[/tex]

Hello, the answer should be [tex]\frac{4}{9}[/tex], C option.
First, let's define the numbers that are a multiple of 2 from the balls we have.
2468Then, we will calculate our probability. To do this correctly, we must divide the amount of expected states into the amount of all the states.
Expected numbers: 2-4-6-8
All numbers: 1-2-3-4-5-6-7-8-9
[tex]P=\frac{{2,4,6,8}}{1,2,3,4,5,6,7,8,9} =\frac{4}{9}[/tex]

Which equation represents the directrix? y = –3 y = 3 x = –3 x = 3
The equation that represents the directrix of y² = 12x is x = -3
How to determine the directrix?The parabola is given as:
y² = 12x
The general equation of a parabola is
(y-y₀)² = 4a(x-x₀)
Where the equation of the directrix is x = x₀ - a
By comparing (y-y₀)² = 4a(x-x₀) and y² = 12x, we have:
4a = 12 and x-x₀ = x
Solve for a in 4a = 12
a = 3
Solve for x₀ in x-x₀ = x
x₀ = 0
Substitute a = 3 and x₀ = 0 in x = x₀ - a
x = 0 - 3
Evaluate
x = -3
Hence, the equation that represents the directrix is x = -3

Graph the function on the coordinate plain
A)what are the x intercepts
B)what is the y intercepts
C)what is the maximum and minimum value
Answer:
it should be C I did something very very similar to this but different questions
Answer:
a) {-6, 2}
b) -12
c) minimum: -16
Step-by-step explanation:
I find a graphing calculator to be a big help. Its graph is attached.
a) The function can be factored as:
f(x) = (x -2)(x +6)
The factors are zero at the x-intercepts: x = 2, x = -6.
b) The y-intercept is the function value when x=0. That is the constant in the function. The y-intercept is -12.
c) The leading coefficient of the function is positive, so its graph opens upward. The extreme value is a minimum. It is found on the axis of symmetry, at the x-value that is halfway between the x-intercepts: x = (2-6)/2 = -2. The function value there is ...
f(-2) = (-2-2)(-2+6) = -4(4) = -16
The minimum is f(-2) = -16.

use Demoiure's Theorem to find (-2-2√3i)³
Let z = -2 - 2√3 i.
Find the modulus of z :
|z| = √((-2)² + (-2√3)²) = √16 = 4
Find the argument of z (note that z lies in the third quadrant):
arg(z) = arctan(2√3/2) - π = arctan(√3) - π = -2π/3
Then in polar form, we have
[tex]z = -2 - 2\sqrt 3\, i = 4 \exp\left(-i\dfrac{2\pi}3\right)[/tex]
By DeMoivre's theorem, the cube of z is
[tex]z^3 = \left(4 \exp\left(-i\dfrac{2\pi}3\right)\right)^3 = 4^3 \exp(-i 2\pi) = \boxed{64}[/tex]

The probability that both are big bombs is 19/30 or 0.63 if the renting Car's Floppy Jalopy Rent-a-Car has 25 cars available for rental-20 big bombs and 5 midsize cars. If two cars are selected at random.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
Renting Cars Floppy Jalopy Rent-a-Car has 25 cars available for rental-20 big bombs and 5 midsize cars. If two cars are selected at random.
Total number of outcomes = C(25, 2) = 300
Total number of favorable outcomes = C(20, 2) = 190
Probability = 190/300 = 19/30 or
= 0.63
Thus, the probability that both are big bombs is 19/30 or 0.63 if the renting Car's Floppy Jalopy Rent-a-Car has 25 cars available for rental-20 big bombs and 5 midsize cars. If two cars are selected at random.

Find the volume of this cone round your answer to the nearest whole number use 3.14 for pi diameter = 5 mm, height = 6 mm
Answer:
Answer = 39.25 or 39 if rounded to the nearest whole number
Step-by-step explanation:
The formula for finding the volume of a cone is h(pi)(r^2)/3. We know that the height is 6 and the diameter is 5. Since we know the diameter we know that the radius is 2.5 since it is one half of the diameter. Now that he know the radius and height we can plug the values into the equation to get V=39.25

In this case, you want to round to the nearest hundredth place value. to round, look at the place value directly right of the place value you are solving for (in this case, the thousandths place value). The value is 6.
Note:
When the value of the digit is 5 or greater, you round up. When the value of the digit is 4 or less, you round down.In this case, the value is 6, so you will round up:

Mean is another way to say the average of a set of numbers. To find the average you need to add all the numbers in the set together, and then divide by the amount of numbers that where given.
In this case:
6 + 8 + 2 + 0 + 4 + 5 + 3 = 28
there are 7 numbers given in the set, so you divide 28 by 7 to get your mean.
28 / 7 = 4
Answer:
4
Step-by-step explanation:
To find the mean of a set of numbers, you add up all the numbers and then divide them by the amount of numbers there are.
So, let's add up these numbers.
6 + 8 + 2 + 0 + 4 + 5 + 3 = 28
Now, there are a total of 7 numbers, so we divide 28 by 7.
28 / 7 = 4
Therefore, the mean of this data set is 4. I hope this helps! Have a lovely day!!
