Answer:

x = 62 and y = 28

Step-by-step explanation:

Solving for x:

\(47+15 = 62\\180-62 = 118\\180 - 118 = 62 \\x = 62\)

Solving for y:

\(62 + 90 =152\\180-152=28\\y = 28\)

Range is R={n^2: n is natural number} U {n(n+1) : n is natural number}

The expression ⌈y⌉⋅⌊y⌋ represents the product of the ceiling and floor functions of y.

To find the range of all possible values of y, we need to consider the possible values of the ceiling and floor functions individually.

1. Ceiling function (⌈y⌉): This function rounds y up to the nearest integer. Since y is greater than 0, the ceiling of y will always be greater than or equal to y.

2. Floor function (⌊y⌋): This function rounds y down to the nearest integer. Again, since y is greater than 0, the floor of y will always be less than or equal to y.

Now, let's consider the product of the ceiling and floor functions, ⌈y⌉⋅⌊y⌋.

The product ⌈y⌉⋅⌊y⌋ will always be greater than or equal to 0 since y > 0 and this can take only integral values.

Therefore, the range of all possible values of y such that ⌈y⌉⋅⌊y⌋ is the set R={n^2: n is natural number} U {n(n+1): n is natural number}

Step-by-step explanation:

Step-by-step explanation:

I don't see the options and how they are written, but I can tell you the right answer in numbers :

sin(F) = 3/5 = 0.6

cos(F) = 4/5 = 0.8

sin(G) = 4/5 = 0.8

cos(G) = 3/5 = 0.6

why ?

remember the norm circle (radius 1) with ask the trigonometric functions.

the sine of an angle is the vertical height from that point in the circle arc down to x-axis.

the cosine of an angle is the length on the x-axis from the center of the circle to the point, where the sine touches the x-axis.

in any case, sine and cosine enclose the right angle (90°).

each function is now defined for the norm circle with radius = 1.

for angles in larger circles we need to divide the find lengths by the actual radius (we formality do this in the norm circle too, but a division by 1 does not change anything).

for the angles at F and G the radius is the side with the length 5.

x = 35

Step-by-step explanation:

110 + 110 = 220

360 - 220 = 140

140 / 2 = 70

70 = 2x

70 / 2 = x

x = 35

Answer:

x=35

Step-by-step explanation:

You can set the equation up like this

2x+110=180

Set x by itself

2x=70

Divide both sides by 2

x = 12.25

y = - 12.78

The given non-linear system of equations is:y2 − x2 = 14 ... (1)

x - y = 25 ... (2)

We are supposed to find the value of y up to two decimal places.

The equation (2) can be rearranged as: x = y + 25

Substituting this value of x in equation (1), we get: y2 − (y + 25)2 = 14

y2 − y2 - 50y - 625 = 14-50

y = 14 + 625-50y = 639

y = - 12.78 (rounded up to two decimal places)

x = y + 25

x = - 12.78 + 25 = 12.25 (rounded up to two decimal places)

Therefore, the value of y is -12.78 up to two decimal places. and x = 12.25

The value of y is 1 and 49 up to two decimal places.

The given system of non-linear equations is as follows:     y²-x² &= 14 and x-y = 25  

Substituting x = y + 25 in y²-x² &= 14 we get,

y² - (y+25)² = 14

y² - y² - 50y - 625 = 14

y² - 50y - 639 = 0

On solving this quadratic equation, we get (y - 1)(y - 49) = 0

Therefore, y = 1 or y = 49.

Substituting each of these values of y in the x-y = 25 we get, For y = 1, x = -24 For y = 49, x = 24

Therefore, the solutions of the given non-linear system of equations are (-24, 1) and (24, 49).

Your answer: A  −14 × {23 + (−47)} = [−14 × 23] + [−14 × (−47)]  This example demonstrates the distributive property of multiplication over addition for rational numbers, which states that for any rational numbers a, b, and c: a × (b + c) = (a × b) + (a × c).

The correct answer is A: −14 × {23 + (−47)} = [−14 × 23] + [−14 × (−47)]. This is an example of the distributive property of multiplication over addition for rational numbers because we are multiplying −14 by the sum of 23 and −47, and we can distribute the multiplication to each term inside the parentheses by multiplying −14 by 23 and −14 by −47 separately, and then add the two results together. This is the basic definition of the distributive property of multiplication over addition. Option B shows the distributive property of multiplication over subtraction, option C shows the product of multiplication and addition, and option D is not a valid equation.

Therefore,  subscript indices must be either positive integers or logical. True

Explanation: The statement "subscript indices must be either positive integers or logicals" is true. Subscript indices are used to identify elements in an array. A positive integer subscript identifies a particular element in an array, while a logical subscript identifies a subset of elements based on a logical condition. For example, if we have an array A, then A(1) would identify the first element of the array, while A(A > 0) would identify all elements in the array that are greater than zero. Subscript indices cannot be negative or non-integer values.

Therefore,  subscript indices must be either positive integers or logical. True

The circumstance that the score is located 5 points above the mean a central value, relatively close to the mean is when the population standard deviation is much greater than 5.

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

Here, we have

We have to find under what circumstances is a score that is 5 points above the mean considered a central value--meaning it is relatively close to the mean.

We concluded from the above statement that when the population standard deviation is much greater than 5.

Hence, when the population standard deviation is much greater than 5 then, the score that is 5 points above the mean is considered a central value.

Therefore, the correct option is D.
