Answer:

vertex = (- 1, - 4 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

y = x² + 2x - 3 ← is in standard form

with a = 1, b = 2 , then

x = - [tex]\frac{2}{2}[/tex] = - 1

Substitute x = - 1 into the equation for corresponding value of y

y = (- 1)² + 2(- 1) - 3 = 1 - 2 - 3 = - 4

vertex = (- 1, - 4 )

Answer:

Step-by-step explanation:

I'm assuming that non-linear means that there is some type of association between the dots, they are just not in a straight line. Now, they definitely are NOT in a straight line, but they do appear to be falling in an exponential pattern. I would say that this is a non-liner association (exponential decay, to be specific).

The figure of the triangle is missing, so i have attached it.

Answer:

BC = 5.4

Step-by-step explanation:

From the attached triangle image, we are given 2 angles, but we need to find the third angle before we can find BC.

We know that sun of angles in a triangle is 180°.

Thus;

∠A = 180 - (∠C + ∠B)

∠A = 180 - (24 + 130)

∠A = 26°

Now, from sine rule, we can find BC.

BC/sin A = AB/sin C

Thus;

BC = (AB sin A)/sin C

BC = (5 × sin 26)/sin 24

BC = 5.389

Approximating to the nearest tenth gives;

BC = 5.4

Answer:

A [and B]

Step-by-step explanation:

If x < 5.3 then anything higher than 5.3 makes the statement false.

16 is too high and therefore is the most obvious fallacy.

5.3 would actually make x=5.3 and therefore x wouldn't be less than 5.3 making it also false but this really depends on what your teacher is looking for.

0 is true.

-8.95 is true.

If there is any clarification in the problem you can provide I can give a more definite answer but now it is really a coinflip!

Step-by-step explanation:

There are 399 stones in the pyramid of 19 layers if there are 3 stones at the top and 2 more stones in each layer below this

An equation is an expression that shows the relationship between two or more numbers and variables.

A small pyramid has 3 stones at the top and 2 more stones in each layer below this. This can be represented as an arithmetic progression with first term (a) = 3 and difference (d) = 2, hence:

number of stones in 19 layers = [tex]\frac{19}{2}(2(3)+(19-1)2)=399[/tex]

Answer:

A. Acute

Step-by-step explanation:

To start, determine whether you can form a triangle or not. In any triangle, the sum of any two sides must be greater than the third side. In this case, this holds true and we can definitely form a triangle.

Let [tex]c[/tex] be the longest side of the triangle and let [tex]a[/tex] and [tex]b[/tex] be the other two sides.

If [tex]a^2+b^2>c^2[/tex], the triangle is acute.

If [tex]a^2+b^2=c^2[/tex], the triangle is right.

If [tex]a^2+b^2<c^2[/tex], the triangle is obtuse.

Substituting given information:

[tex]7^2+9^2>11^2[/tex], therefore the triangle is acute.

Answer:

D)24˚

Step-by-step explanation:

Since you know a full turn is 360˚ since we need to find "b"

we add 41˚ with 295˚

which is 336

then subtract 360 with 336

which is 24˚

So the answer is D) 24˚

Hope this helps!

Answer:

hi there user!

The correct answer should be option D!

Step-by-step explanation:

circle angle: 360 degrees

360 - (295 + 41) =

360 - 336 =

24

Answer:

There are 2,520 unique permutations.

Step-by-step explanation:

When we have a set of N different elements, the total number of permutations is given by:

P = N! = N*(N - 1)*(N - 2)*...*(2)*(1)

Particularly, if out of these N elements, there are a given element that is repeated K times, then the permutations of these K elements actually do not add new unique permutations, then in that case the total number of unique permutations is:

P = N!/K!

And if we have another element that is repeated L times, then with the same reasoning than above, the total number of unique permutations is:

P = N!/(K!*L!)

Now, we have the set:

{C, E, A, S, E, L, E, S, S}

So we have a set of 9 letters, then:

N = 9

And, the letter S is repeated 3 times

The letter E is repeated 3 times

Then, using the above notation, we can define:

K = 3

L = 3

The total number of permutations is then:

[tex]P = \frac{9!}{3!*3!} = \frac{9*8*7*6*5*4*3*2*1}{3*2*1*3*2*1} = \frac{9*8*7*6*5*4}{3*2*1} = 2,520[/tex]

So there are 2,520 unique permutations.

The two angles are supplementary angles, which when added together equal 180 degrees.

6x -10 + 6x +10 = 180

Combine like terms:

12x = 180

Divide both sides by 12:

x = 180/12

x = 15

The answer is C) 15
