Is a whole number no solution, all real numbers, or infinitely many solutions? My number is -24

Answer:

90

Step-by-step explanation:

First, we would need to figure out the multiples of 18.

18, 36, 54, 72, 90, 108, 126, 144, 162, 180.

Now, let's figure out the multiples of 30.

30, 60, 90, 120, 150, 180.

A vector Y is orthogonal to vectors U and V, so Y is orthogonal to the vector (U+V).

In the given question,

Suppose that a vector Y is Orthogonal to vectors U And V.

We have to show that Y is orthogonal to the vector U + V.

As to vectors are orthogonal if and only if their dot product is zero.

So Y∙U = 0 and Y∙V = 0.

To prove that Y is orthogonal to the vector(U+V), we have to show that Y∙(U+V) = 0.

As dot product is distributive. Now

Y∙(U+V) = Y∙U + Y∙V

As Y∙U = 0 and Y∙V = 0. So

Y∙(U+V) = 0 + 0

Y∙(U+V) = 0

Hence, Y is orthogonal to the vector (U+V).

Assume that the basis for a subspace V in Rn is v1,..., vp. Show that a vector in Rn is orthogonal to a vector in V if and only if it is orthogonal to every vector v1,..., vp.

An orthogonal vector , In mathematics, orthogonality is an extension of perpendicularity, particularly in vector calculus and linear algebra. Basic geometry dictates that two lines or line segments are only perpendicular if they form a straight angle.

It makes sense to think of vectors as arrows, such as R 2 and R 3, when discussing orthogonal vectors in an inner product space (a real or complex vector space with a notion of vector multiplication).

There are inner product spaces where it makes no sense to conceive of vectors as arrows, yet one still needs to have some understanding of what it means when discussing orthogonal vs. perpendicular.

Hence, It is orthogonal to every vector in vector space, or o V. Every vector in V is a linear combination of these vectors since v1,..., vp serves as the basis for V.

Answer:(4, 4), (7, 0), (4,-2)

Step-by-step explanation: The median of a triangle is the line segment connecting a vertex to the midpoint of the opposite side. In this triangle, the vertex at (7, 4) is connected to the midpoint of the side opposite it, which is the midpoint of the line segment between (1, 4) and (7, -2). This midpoint is located at (4, 0). Therefore, the median through (7, 4) will consist of the points (4, 4), (7, 0), and (4, -2).

The slope of the curve at the given point is approximately -28

What is the derivative of a function?

Geometrically, the derivative of a function can be interpreted as the slope of the graph of the function or, more precisely, as the slope of the tangent line at a point. Its calculation, in fact, derives from the slope formula for a straight line, except that a limiting process must be used for curves.

To find the derivative of y with respect to x using implicit differentiation, we need to take the derivative of both sides of the equation cos(y) = 7x^4 - 7.

On the left side of the equation, we can use the chain rule to find the derivative of cos(y) with respect to x:

d/dx[cos(y)] = -sin(y) * dy/dx

On the right side of the equation, we can use the power rule to find the derivative of 7x^4 - 7 with respect to x:

[tex]d/dx[7x^4 - 7] = 28x^3[/tex]

Substituting these expressions into the original equation, we get:

[tex]-sin(y) * dy/dx = 28x^3[/tex]

To solve for dy/dx, we can divide both sides of the equation by -sin(y):

[tex]dy/dx = -(28x^3)/sin(y)[/tex]

To find the slope of the curve at the given point, we need to substitute the values of x and y into the expression for dy/dx.

The slope at (1, π/2). would be

slope = -(28((1)^3))/sin(π/2) = -28.

Hence, the slope of the curve at the given point is approximately -28.

About -$10.15 that is, on average you lose about 15 cents.

Using the principle of discrete probability, the expected value, which is a measure of the mean amount after many plays is - 2/13

Calculating the required probabilities :

P(winning) = P(drawing an Ace) = 4/52 = 1/13

Hence, P(losing) = 1 - 1/13 = 12/13

X :____ 10 _____ - 1

P(X) : _ 1/13_____ 12/13

The expected value :

E(X) = 10 × (1/13) + - 1(12/13)

E(X) = 10/13 - 12/13

E(X) = - 2/13

Hence, the measure of the mean amount is -2/13.

The victory value is $10, and the loss value is $-1.

Out of a total of 52 cards, this deck has 4 aces.

The probability can then be defined as the ratio of the number of desirable outcomes to the number of possible outcomes.

P(win) = number of favorable outcome/number of the possible outcome

= 4/52

= 1/13

P(loss) = number of favorable outcome/number of the possible outcome

= 48/52

= 12/13

Then we have

$10x1/13 + (-1)x12/13

What is the area?

The area of a shadow is the amount of surface area that is covered by the shadow. It is the two-dimensional projection of an object onto a surface.

Let the distance between the point source of light and the horizontal surface be h. Since the shadow is a projection of the cube onto the horizontal surface, the shadow has the same proportions as the cube. Therefore, the height of the shadow is h/x times the length of the shadow, which is 48x. The area of the shadow is then:

48x * h/x = 48h

Since the area of the shadow is 48x^2, we have:

48h = 48x^2

h = x^2

We are asked to find the greatest integer that does not exceed 1000x. Substituting the expression for h into the equation, we get:

1000x = 1000x^2

A population numbers 12,000 organisms initially and grows by 17.5% each year. The growth function of the population is P =  12,000 x 1.175^t

An exponential growth function can be written as:

P = A (1 + r)ⁿ

Where:

P  = quantity after n periods

n = number of periods

r = growth rate per period

A = initial quantity

In the given problem, the period is the number of years t

A = 12,000

r = 17.5% = 0.175

Hence, the growth function:

P = 12,000  (1 + 0.175)^t

P = 12,000 x 1.175^t

Answer:

Step-by-step explanation:

-3x - 2y = -20

3x + y =    10

-y = -10

y = 10

3x + 10 = 10

3x = 0

x = 0

(0, 10)

Part A

p = number of levels

8p = amount of points lost for passing a level

3p = amount of points lost for catching a flower

(6x3)p = multiply the previous expression by 6 since there are 6 flowers per level. This represents the total number of points lost after catching 6 flowers. This expression is equivalent to (3 x 6)p, both of which simplify to 18p.

The quantities 8p and (3 x 6)p are subtracted from the total 100. Then we set that less than 20 to end up with the inequality of

100-8p - (3 x 6)p < 20

===================================================

Part B

Refer to the inequality set up in part A.

We'll solve for p.

100-8p - (3 x 6)p < 20

100-8p-18p < 20

100-26p < 20

-26p < 20-100

-26p < -80

p > -80/(-26) ..... inequality sign flips

p > 3.077

The decimal result is approximate. The inequality sign flips because we divided both sides by a negative number.

Round this value up to the nearest integer.

So p = 3.077 rounds up to p = 4. We do not go to p = 3 because

100-26p = 100-26*3 = 22

which is not under 20.

But p = 4 will work
