Both blanks are 9
Third answer, factor the trinomial and simplify:
(x + -3 )²= -4
Use the square root property of equality to solve
(x – 3)2 = –4.
The solutions are
The correct option is C. 3 ± 2i.
:D
The equation 8x² - 48x = -104 can be rewritten with 'a' = 1 by dividing all terms by 8 and rearranging to the form ax² + bx + c = 0, yielding x² - 6x + 13 = 0.
Explanation:To rewrite the equation so that 'a' = 1, it would be useful to adjust the coefficients in your equation first. Starting with the given equation: 8x² - 48x = -104. We can divide all terms by 8 to normalize the 'a' coefficient.
Doing that gives us: x² - 6x = -13. Now, to write the equation in the form ax² + bx + c = 0, we can add 13 to both sides which results in: x² - 6x + 13 = 0. Now your equation is in the standard quadratic form with 'a' = 1.

The diameter of the moon is 2155 miles. Find volume of the moon. Round answers to the nearest whole number and leave pi in the answer
Answer: [tex]1667978979\pi[/tex] cubic miles
Step-by-step explanation:
We know that the shape of moon is sphere.
The volume of sphere is given by :-
[tex]\text{V}=\dfrac{4}{3}\pi r^3[/tex], where r is the radius of sphere.
Given : The diameter of moon = 2155 miles

A phane takes off at an angle of elevation of 15 ° and travels in a straight line for 3,000 meters. What is the height of plane above the ground at this instant ?
Final answer:
The height of the plane above the ground after traveling 3,000 meters at a 15° angle of elevation is approximately 776.4 meters. This is calculated using the sine function: height = 3,000 m × sin(15°).
Explanation:
To find the height of the plane above the ground after taking off at an angle of elevation of 15° and traveling for 3,000 meters, we can use trigonometric functions. Specifically, the sine function relates the opposite side of a right-angled triangle (in this case, the height above ground) to the hypotenuse (the distance traveled by the plane).
The sine of an angle in a right triangle is equal to the length of the opposite side divided by the length of the hypotenuse. The formula is:
height = hypotenuse × sin(angle)
Here, the hypotenuse is the distance traveled by the plane (3,000 m), and the angle is 15°. Thus, the calculation would be:
height = 3,000 m × sin(15°)
We can calculate the sine of 15° using a calculator.
height = 3,000 m × 0.2588 (approximately)
height = 776.4 m (approximately)
Therefore, the plane is approximately 776.4 meters above the ground.

If 30% of John's photographs were perfect, but 210 photographs were not perfect, then how many photographs were there in all?
To find the total number of photographs, we use the fact that 30% were perfect, meaning 70% were not perfect. By setting up the equation 0.70x = 210, we can solve for x, finding that there were 300 photographs in total.
If 30% of John's photographs were perfect and 210 were not perfect, determining the total number of photographs involves understanding percentages and basic algebra. Here's the step-by-step breakdown of solving the problem:
Let's call the total number of photographs 'x'.Since 70% of the photographs are not perfect (as 30% are perfect), we know that 0.70x equals the number of not perfect photographs.We can set up the equation: 0.70x = 210.To find 'x', divide both sides of the equation by 0.70: x = 210 / 0.70.This gives us the total number of photographs, x = 300.Therefore, there were 300 photographs in total.
The total number of photographs is 300.
If 30% of John's photographs were perfect, it means that 70% were not perfect. Since 210 photographs were not perfect, we can set up an equation to find the total number of photographs. Let x represent the total number of photographs. We know that 70% of x equals 210:
[tex]\[ 0.70x = 210 \][/tex]
Solving this equation, we find that
[tex]\( x = \frac{210}{0.70} = 300 \)[/tex]
Therefore, there were 300 photographs in total. This calculation assumes that all photographs are either perfect or imperfect, with no other categories.

Lucas has five buttons in a container. Each button is a different shape. There is a star, an oval, a hexagon, a circle, and a heart. He picks one button, replaces it, and then picks another button. The sample size for this compound event is__ . Suppose one square-shaped button is added to the container. If Lucas repeats the same picking process, then the sample size would be__ .
Answer:
25,35
Step-by-step explanation:
Part A: There are five buttons in all in all in the given item. The item above can be answered through the fundamental principles of counting.
There are 5 items to choose from during the first pick. Because the shape can be returned and picked again, there are also 5 items to choose from in the second pick. Multiplying them,
n = 5 x 5 = 25
Therefore, the sample size for the compound event is equal to 25.
Part B: The same concept can be used in this part of the item; however, instead of 5 there are 6 buttons to choose from.
n = 6 x 6 = 36
Hence, the sample size of this picking process is 36.
A circle is centered at the point (-3,2) and passes through the point (1,5). What's the radius
radius = square root (( x2-x1)^2 +(y2-y1)^2)
= sqrt(1-(-3)^2+(5-2)^2
= sqrt(16+9)
=sqrt(25)
= 5
radius is 5
The radius of the circle is [tex]\boxed{5{\text{ units}}}.[/tex]
Further explanation:
The standard equationof the circle with center [tex]\left( {h,k}\right)[/tex] and radius r can be expressed as,
[tex]{\left( {x - h}\right)^2} + {\left({y - k} \right)^2}= {r^2}.[/tex]
Given:
A circle with center at [tex]\left({ - 3,2} \right).[/tex]
The passing through point is [tex]\left( {1,5} \right).[/tex]
Explanation:
The center is at [tex]\left( { - 3,2} \right).[/tex]
The passing through point is [tex]\left( {1,5} \right)[/tex]. Therefore, the point satisfies the equation of circle.
Substitute 1 for x, 5 for y, -3 for h and 2 for k in general equation of the circle to obtain the radius of circle.
[tex]\begin{aligned}{\left( {x - h}\right)^2}+{\left({y - k}\right)^2}&={r^2}\\{\left( {1 + 3} \right)^2} + {\left( {5 - 2}\right)^2}&= {r^2}\\16 + 9&= {r^2}\\\sqrt{25}&= r\\5&= r\\\end{aligned}[/tex]
The radius of the circle is [tex]\boxed{5{\text{ units}}}.[/tex]
The radius of the circle is [tex]\boxed{5{\text{ units}}}.[/tex]
