What is an eclipse?
An eclipse can be defined as an astronomical event that occurs when an object or spacecraft is obscured as the shadow of another body passes or when another body pass between it and an observer.
The axis of an eclipse could major or minor.
The minor axis of an ellipse is the line that contains the shorter part of the two line segments about which the ellipse is symmetrical. It is perpendicular to the major axis and passes through the center of the axis.
Therefore, the term that best describes the red line segment of the ellipse is minor axis . C

Step-by-step explanation:
whats f? 0.62(f + –6) + 6.96 = 8.2
Answer:
f=8
Step-by-step explanation:
0.62(f+(-6)+6.96=8.2
0.62(f-6)+6.96=8.2
multiply both sides by 100
0.62(f-6)*100+6.96*100=8.2*100
Refine
62(f-6)+696=820
Subtract 696 from both sides
62(f-6)+696-696=820-696
Simplify
62(f-6)=124
Divide both sides by 62
62(f-6)/62 = 124/62
Simplify
f-6=2
add 6 to both sides
f-6+6=2+6
simplify
f=8
Answer:
8
Step-by-step explanation:
1. Distribute 0.62 to each term in the parenthesis:
0.62(f) + 0.62(-6)
0.62f - 3.72 + 6.96 = 8.2
2. Add 3.72 and 6.96:
0.62f - 3.72 + 6.96 = 8.2
0.62f + 3.24 = 8.2
3. Subtract 3.24 from both sides of the equation:
0.62f + 3.24-3.24 = 8.2-3.24
0.62f = 4.96
4. Divide 0.62 by both sides to isolate f:
0.62f/0.62 = 4.96/0.62
f = 8

2x times x = 2x2
2x times 2 = 4x
5 times x = 5x
5 times 2 = 10
The factors are (2x + 5) and (x + 2), so 2x2 + 9x + 10 = (2x + 5) × (x + 2)
4x and 5x are interchangeable, so you could put 5x in the first row and 4x in the second row and still get the same answer.

One figure models 1/4 as 4 of 12 equal parts of a whole. The other models 1/3 as 1 of 3 equal parts of a whole. What is true about the equal parts for the two fractions?
The correct option for this questions is Option C
Equivalent Fractions for 4/12:
1/3, 2/6, 3/9, 4/12, 5/15, 6/18, 7/21, 8/24, 9/27, 10/30, 11/33, 12/36, 13/39, 14/42, 15/45, 16/48, 17/51, 18/54, 19/57, 20/60, and so on ...
How do you find equivalent fractions?Two frations are equivalent when they have the same value when written in lowest terms. The fraction 8/24 is equal to 1/3 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (1/3) by any interger number, ie, multiply by 2, 3, 10, 30.
2/6 is equivalent to 4/12 because 1 x 2 = 2 and 3 x 2 = 63/9 is equivalent to 4/12 because 1 x 3 = 3 and 3 x 3 = 94/12 is equivalent to 4/12 because 1 x 3 = 4 and 3 x 3 = 12Equivalent fractions may look different, but when you reduce then to the lowest terms you will get the same value. If any fraction is not reduced to lowest terms, you can get other equivalent fractions just dividing both numerator and denominator by the same number.

Hey there!
72 * 1/8 = 9
= 72/1 * 1/8
= 72(1) / 1(8)
= 72 / 8
= 72 ÷ 8

4. Maryam's average monthly expenses are $3,750. She wants to have an emergency fund that
covers 3 months of expenses saved up within the next 24 months. If she's starting with $300 in
her account, how much does she need to save each month to reach that goal?
Answer:
$456.25 each month
Step-by-step explanation:
Fund for 3 months 3750 * 3 = 11250
Start with 300 => 11250 - 300 = 10950
Within 24 months to reach 10950 => each month = 10950 / 24 = 456.25
She needs to save $456.25 each month for the next 24 months to reach her goal.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Monthly expenses = $3,750
For 3 months = 3 × 3750 = $11250 need to save total.
Since she started with $300 so
11250 - 300 = $10950 need to save total.
Let's say the amount per month is x
24x = 10950
x = 456.25.
Hence "She needs to save $456.25 each month for the next 24 months to reach her goal".

A gardener wants to fence in her plot in two equal rectangular sections. If she has 54 yards of fence and the area of the entire plot is 108 square yards, find the possible dimensions of the garden.
Considering the perimeter and the area of the rectangle, the possible dimensions are of 22.11 yards and 4.89 yards.
What are the area and the perimeter of a rectangle?Considering a perimeter of length l and width w, we have that:
The area is lw.The perimeter is 2(l + w).In this problem, considering the amount of fencing as the perimeter, and the area, we have that:
2(l + w) = 54 -> l + w = 27 -> w = 27 - l.lw = 108.Then:
l(27 - l) = 108
l² - 27l + 108 = 0.
Which is a quadratic equation with coefficients a = 1, b = -27, c = 108, then:
[tex]\Delta = b^2 - 4ac = (-27)^2 - 4(1)(108) = 297[/tex]
[tex]x_1 = \frac{27 + \sqrt{297}}{2} = 22.11[/tex]
[tex]x_2 = \frac{27 - \sqrt{297}}{2} = 4.89[/tex]

Answer:
[tex]\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}[/tex]
( i )
given - a cylinder with base diameter = 10 cm ! And , height = 12 cmTo find - CSA of conenow ,
since diameter = 10 cm
[tex]\implies \: radius = \frac{10}{2} = 5 \: cm \\ [/tex]
now ,
[tex]slant \: height \: ( \: l \: ) = \sqrt{h {}^{2} + r { }^{2} } \\ \\ \implies \: \sqrt{(12) {}^{2} + (5) {}^{2} } \\ \\ \implies \: \sqrt{144 + 25} \\ \\ \implies \: \sqrt{169} \\ \\ \implies \: 13 \: cm[/tex]
now ,
[tex]CSA \: of \: cone = \pi \: \times r \times l \\ \\ \implies \: \pi \: \times 5 \times 13 \\ \\ \implies \: 65\pi \: cm {}^{2} [/tex]
_____________________________
_____________________________
( ii )
now when we flatten the cone ,
the slant height becomes the radius of the sector , while the arc becomes the circumference of cone !
[tex]\therefore \: radius = l = 13 \: cm \\ \\ arc \: length = circumference = 2\pi \: r[/tex]
now ,
[tex]s = d \: \theta \: ( \: for \: a \: sector \: ) \\ \\ \therefore \: l\theta \: = 2\pi \: r \\ \\ \implies \: \theta = \frac{2\pi \: r}{l} \\ \\ \implies \: \theta = \frac{2 \times \pi \times 5}{13} \\ \\ \implies \: \theta \: = \frac{10\pi}{13} \\ \\ \implies \theta \: = \: 0.77 \pi [/tex]
hope helpful :D
Step-by-step explanation:
i)
remember, the radius is half the diameter !
the overall surface area of a cone (base circle + "mantle", the lateral, curved surface) is
A = pi×r × (r + sqrt(h² + r²))
so, only the "mantle" or lateral curved stave area is
pi×r × sqrt(h² + r²) = pi×5 × sqrt(12² + 5²) = pi×5×sqrt(169) =
= pi×5×13 = 65×pi cm²
ii)
the length of the arc of the sector is the circumference of the circle, that was the base of the original cone.
that is
2×pi×r = 2×pi×5 = 10×pi cm
the total circumference of the large circle containing that sector is
2×pi×r' = 2×pi×sqrt(h² + r²)
as the radius r' of the circle containing the sector (representing the "mantle" of the cone) is the lateral height of the cone (the distance along its side from the base to the top). and that is per Pythagoras simply the square root of the sum of the square of the inner height and the square of the base radius.
in our case that is
2×pi×sqrt(12² + 5²) = 2×pi×13 = 26×pi cm
the angle of the sector is then 10/26 of the total of 360° for the whole circle :
360 × 10/26 = 138.4615385...°
or, if you need this in terms of pi too, remember that 360° are represented by 2×pi (the arc length of the standard circle).
2×pi × 10/26 = pi × 20/26 = pi × 10/13 =
= 0.769230769... × pi

Cyclic integration is the integration over a closed loop.Close the path by connecting D to A. Then by Green's theorem, the integral over the closed path ABCDA - which I'll just abbreviate C - is
[tex]\oint_c(Sin(x)+9y)dx+(4x+y)dy\\\\\\[/tex]

The remaining double integral is -5 times the area of the trapezoid, which is
[tex]-5 \int\int dxdy=\dfrac{-5}{2}\times (12+4)\times 4=-160[/tex]
To get the line integral you want, just subtract the integral taken over the path DA. On this line segment, we have x = 0 and dx = 0, so this integral reduces to
