Belinda's GPS system worth $400 was stolen out of her car. If Belinda's insurance policy summary is given below, how much will Belinda receive from her insurance company when she files her claim?
Summary
Comprehensive Deductible: $375
Collision Deductible: $550
Premium of $625 for 4 months
Answer:
Belinda will get $25 from her insurance company when she files her claim.
Step-by-step explanation:
Comprehensive insurance covers your car from damage from fire, theft or falling objects like trees etc.
To get the claim, the company will check the worth of the GPS system in the market minus the deductible amount.
So, the cost of GPS system was $400. And comprehensive deductible is $375.
So, Belinda will receive [tex]400-375=25[/tex] dollars
The answer is: Belinda will get $25 from her insurance company when she files her claim.

The wrong statement about a circle is c. Every chord is a diameter
Further explanationCircles are two-dimensional builds which are sets of equidistant points at a point called the center point
The distance of these points to the center is called the radius of the circle. While the circle field is an area which is bounded by a circle
There are terms - terms commonly used in circles:

LensA diameter is a line that passes through the center of a circle and divides the circle into two equal partsA Secant is a plotline that intersects a circle at two points on a circleA chord is a line that cuts a circle at 2 points located on the arcLet we see the answer choices :
a. Every chord is a part of a secantRight, because secant itself is an extension of the chord
b. Every diameter is a part of secantRight, because the diameter itself also intersects the circle at two points on the circle, just like secant
c. Every chord is a diameterIncorrect, because the diameter itself must pass through the center point while the chord does not have to
d. Every diameter is a chordRight, because each diameter intersects a circle at two different points

Point x starts at -4 on a number line. Pint x then goes through a series of moves; +3 units, -2 units, +6 units and -5 units. What is the final position of Point x?
Starting from -4 and applying a series of moves (+3, -2, +6, -5) sequentially on the number line, the final position of Point x is -2.
Explanation:The question involves finding the final position of Point x after a series of moves on a number line. Starting from -4, we apply the moves in sequence: adding 3, subtracting 2, adding 6, and finally subtracting 5. The operations are as follows:
Start: -4After adding 3: -4 + 3 = -1After subtracting 2: -1 - 2 = -3After adding 6: -3 + 6 = 3After subtracting 5: 3 - 5 = -2Therefore, the final position of Point x on the number line is -2.

Which number is closest to V65 A. 8 B. 9 C. 32 D.64
The symbol 'V' before a number usually implies the square root in mathematics. Therefore, the square root of 65 (V65) is approximately 8.06. Hence, the closest number to V65 is 8.
Explanation:The symbol 'V' before a number often denotes the square root in mathematics. Thus, 'V65' implies the square root of 65. Calculating this gives an approximate value of 8.06. When you compare this value to the options provided: A. 8, B. 9, C. 32 and D. 64, you can see that the closest number to V65 (the square root of 65) is A. 8.

is the relation a function? Why or why not?
(-3, -2) (-1, 0) (1, 0) (5, -2)
A. no- to domain values exist for range value -2
B- yes- only one range value exists for each domain value
C- yes- to domain values exist for range value -2
D- no- the relation passes the vertical line test
Final answer:
A relation where each domain value is mapped to a single, unique range value is considered a function. The relation in question is indeed a function because each domain value corresponds to only one range value, and its correctness is supported by the distinct pairs of the domain and range. The correct answer is option (B)
Explanation:
To determine whether a given relation is a function, we check if each element of the domain maps to exactly one element of the range. The relation in question is composed of the following ordered pairs: (-3, -2), (-1, 0), (1, 0), (5, -2). The domain (which consists of the first elements of the ordered pairs) includes -3, -1, 1, and 5, and the range (the second elements) includes -2, 0.
A crucial aspect of a function is that each domain value is paired with a unique range value. Here, we see that no domain value is repeated; hence, none of them map to more than one range value. This satisfies the criterion for a function. However, it is not a problem that a range value, like -2, appears more than once in the relation as long as it corresponds to different domain values.
Based on this, the correct answer would be "B. yes- only one range value exists for each domain value" because each domain value is associated with one and only one range value, which is the definition of a function.

Variable x is 7 more than variable y. Variable x is also 1 less than y. Which of the following pairs of equations best models the relationship between x and y? (4 points)
x = 1y
x = y + 7
x = y + 7
x = y – 1
y = x + 8
y = x – 1
y = 7x
y = x + 1
Answer:
1. x is 7 more than y
meaning
x=y+7
2. x is 1 less than y
meaning
x=y-1
so
the answer:
x = y + 7
x = y – 1

A circle with center (-2,6) passes through the point (-2,10). Which of the following is the equation of the circle?
First option is correct. The equation of the is [tex](x-2)^{2} +(y-6)^{2} =16[/tex].
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called "center".
General equation for circle[tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]
where,
(h, k) is the coordinate of the center of a circle
(x, y) are the coordinate points
r is the radius of circle.
According to the question
we have
the center of the circle, (h, k) = (-2, 6)
and the circle passes through the point (-2, 10)
since, the circle passes through point (-2, 10), the radius(r) of the circle is the distance between the points (-2, 6) and (-2, 10)
⇒ [tex]r =\sqrt{(-2+2)^{2 }+ (6-10)^{2} }[/tex]
⇒ r = [tex]\sqrt{0^{2}+(-4)^{2} }[/tex]
⇒[tex]r = \sqrt{16}[/tex]
⇒[tex]r = 4unit[/tex]
therefore,
the equation of the circle is given by
[tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]
[tex](x-(-2))^{2} +(y-6)^{2} =16[/tex]
[tex](x+2)^{2} +(y-6)^{2} =16[/tex] ..... (1)
[tex]x^{2} +4+4x+y^{2} +12y+36 = 16[/tex]
[tex]x^{2} +y^{2} +4x+12y+24=0[/tex]
Hence, equation 1 represent the equation of circle i.e. [tex](x+2)^{2} + (y-6)^{2} =16[/tex]
