Ishi bought a $6.95 canvas and 8 tubes of paint. She spent a total of $24.95 on the canvas and paints. Determine the cost of each tube of paint.

The price of the share of stock in fossil oil refineries after the three-for-one split is $50.

A stock split is an event in the stock market when the company declares split of stock into multiple parts to decrease the cost per share and make it easier to purchase.

Given,

          The selling price of a stock in fossil fuel before split = $150

          After one year the stock split into three parts

         ∴ Probable prices per share = Price before split/3

                                                         = $150/3

If the magnitude of two vectors is 10 and 6 and their dot product is 30, then the angle between the vectors is 60°.

What is a vector?

A vector in mathematics is a quantity that not only expresses magnitude but also motion or position of an object in relation to another point or object. Euclidean vector, geometric vector, and spatial vector are other names for it.

There are two ways to define a dot product: algebraically and geometrically. The sum of the products of the matching entries of the two number sequences is the definition of the dot product in algebra. Geometrically, it is the sum of the cosine of the angle formed by the two vectors and their Euclidean magnitudes.

The magnitude of the vector 1 is, |a| = 10

The magnitude of the vector 2 is, |b| = 6

The dot product of the two vectors is, a·b = 30.

The formula for dot product of vectors is -

a·b = |a| |b| cos θ

Solve the equation to get the angle -

30 = (10 × 6) cos θ

30 = 60 cos θ

cos θ = 30/60

cos θ = 1/2

θ = cos^-1 (1/2)

θ = 60°

Therefore, the angle is obtained as 60°.

To find the value of f(g(-4)), we need to first substitute -4 into the definition of g(x) and then substitute the result into the definition of f(x).

First we substitute -4 into g(x):

g(-4) = 2(-4)^2 + 4(-4) - 8

g(-4) = 2(16) + (-16) - 8

g(-4) = 32 - 16 - 8

g(-4) = 8

Now we substitute 8 into f(x):

f(g(-4)) = f(8) = 2(8) - 4 = 16 - 4 = 12

So the value of f(g(-4)) is 12.

Answer:

28

Step-by-step explanation:

The expression: f(g(-4)) just means calculate the value of g at x = -4 and then calculate what f is equal to at that value g is equal to, so we have to first calculate g(-4) which we can do by substituting in -4 as x.

g(-4) = 2(-4)^2 + 4(-4) - 8

g(-4) = 2(16) - 8 - 8

g(-4) = 32 - 16

g(-4) = 16

Now from here we can substitute 16 as g(-4) in the expression f(g(-4)) which means we want to evaluate g(16) which we can do by substituting in 16 as x.

f(16) = 2(16) - 4

f(16) = 32 - 4

f(16) = 28

So that means f(g(-4)) = 28

In order to prove that the quadrilateral is a parallelogram, we must have four points to calculate the lengths of the sides and angles. We need to verify that the opposite sides of the quadrilateral are equal in length and that the opposite angles are equal. We can use the formula for the area of a parallelogram: A = b*h, where b is the length of the base and h is the height of the parallelogram. We can also use the formula for the sum of the angles of a quadrilateral: A1 + A2 + A3 + A4 = 360 degrees.

given A = 51 , b₁ = 10 and b₂ = 7 , then

if the area of the trapezoid is [tex]51m^{2}[/tex] and parallel sides are [tex]7m[/tex] and [tex]10m[/tex].

To find the height of the trapezoid, substitute the area and parallel sides into the formula for the area of the trapezoid.
