Answer:

your answer will be -42,-10,-8,-6

Answer:

The dot product is -2

The required dot product of (3,-1) and (1,5) is -2.

Evaluate the dot product of (3,-1) and (1,5).

It is a principle to combine two vectors. It tells about how much two vectors approaching in the same direction.

Now converts the coordinates to vector form.
a = 3i -1j
b = 1i + 5j
Dot product of two vectors a and b,
a.b = 3x1 - 1x5
a.b = 3-5
a.b = 2

Thus, the required dot product of (3,-1) and (1,5) is -2.

Answer:

The inverse is

f^-1(x) = (1/√2)x^¼

And it is a function

Step-by-step explanation:

Given f(x) = 4x^4

Let y = f(x), so that

y = 4x^4

Then dividing both sides by 4

x^4 = y/4

Taking the fourth root of both sides

x = (y/4)^¼

x = (1/√2)y^¼ = f^-1(y)

Put y = x

y = (1/√2)x^¼ = f^-1(x)

This is the inverse.

f^-1(x) is a function.

Answer:

1  5/9

Step-by-step explanation:

9 1/3 can be rewritten as 28/3. The question is asking for you to divide 28/3 by 6. 6 is 6/1, so the expression is 28/3 divided by 6/1. You then do the reciprocal of 6/1 and the expression is [tex]\frac{28}{3} * \frac{1}{6}[/tex]. This gets you 28/18, which is simplified to 14/9 or 1  5/9. Hope this helps!

Answer:

y = 5

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre ad r is the radius

Given

x² + y² - 10y + 18x = 2 ( Rearrange collecting x and y terms together )

x² + 18x + y² - 10y = 2

Using the method of completing the square

add ( half the coefficient of the x/ y term )² to both sides

x² + 2(9)x + 81 + y² + 2(- 5)y +25 = 2 + 81 + 25

(x + 9)² + (y - 5)² = 108 ← in standard form

with centre = (- 9, 5 )

The y- coordinate of the centre is therefore y = 5

Answer:

LAST ONE IS angle JLK congruent to angle LNM, SAS

Step-by-step explanation:

The triangles JLK and LMN are similar by SAS congruence theorem, LJK≅ LNM.

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

The triangles JLK and LMN are similar triangles.

Which means the sides are proportional and those angles are congruent.

We have to prove that JLK is similar to LMN.

By SAS rule we have "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".

So LJK≅ LNM.

The problem with reporting this result is:

Missing data.

Step-by-step explanation:

The reason behind this answer is: first of all a loaded question has a bias, the question in our case is arbitrary because it doesn't suggest an inclination of perspective. The correlation between studies and salaries also is not wrong, it is well developed. Therefore, the casualty is well developed. There is no voluntary response because it was not a questionnaire that could have been manipulated. We could have obtained the data from the government database. However, that is what we are lacking. We have no statistics, no source, no institution mentioned, we have missing data.

Answer:

The amount of carbon in the trees and in the deer . . .

A) has increased.

Explanation:

Carbon is the basis for all living cells, it is responsible for the making and storing of energy. So if the number of energy storage molecules increases, the amount of carbon will increase because carbon is used to make those molecules.

Your question on carbon dioxide and photosynthesis having an effect is valid, but the loss of carbon wouldn't be much compared to the energy storage molecules, so we wouldn't consider that a factor in this case.

If this answer is correct, please make me Brainliest!

The required function that are in the graph is  F(x)=1/2x^4+x^3+x.

Graph has been given, function to be determine.

Functions is the relationship between sets of values. e g y=f(x).

From the graph, function gives y = 0 twice when x =0 and x= -2.3
The only  function that gives y = 0 for x =0 and x= -2.3 is F(x)=1/2x^4+x^3+x.
