Help please.

state the scale factor.

Answer:

x = 10

Step-by-step explanation:

Diagonals of a rhombus bisect each other at a 90° angle, but most importantly (for this problem), they bisect the opposite angles of the rhombus equally.

This means that the two angles, given by the expressions (6x + 12) and (8x - 8), are equal to each other.

Set them equal to each other in an equation and solve for x.

Subtract 6x from both sides.

Add 8 to both sides.

Divide both sides by 2.

The value of 10 for x will make the given parallelogram a rhombus.

Answer:

[tex]h=4x^3+18[/tex]

Step-by-step explanation:

Given that,

The area of a triangle, [tex]A=14x^5 + 63x^2[/tex]

Base, [tex]b=7x^2[/tex]

We need to find the height of the triangle.

The formula for the area of the triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h\\\\\text{h is height}\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times (14x^5 + 63x^2)}{7x^2}\\\\h=\dfrac{2\times 7x^2(2x^3 + 9)}{7x^2}\\\\h=2(2x^3+9)\\\\=4x^3+18[/tex]

So, the height of the triangle is [tex]4x^3+18[/tex].

Step-by-step explanation:

Answer:

She should go with service 2 because it is, cheaper. Service 1 cost $107.52, but service 2 cost only $105.

Step-by-step explanation:

Cost now+increase$=new cost

(Part=percent*whole)

Increase=percent increase*cost now

i=12%*$96

i=0.12*96=$11.52

$96+11.52=107.52

Service two⬇️

8.72*12=$105

Yes Clare should switch to service 2 because; cheaper it costs only $105 which is lesser than $107.52

To find the new cost, we will use the expression;

New Cost = Present Cost + increase

However,

Increase = percentage increase * present cost

Increase = 12% * $96

Increase = 0.12 * 96

Increase = $11.52

Thus;

New Cost  = $96 + 11.52

New Cost = $107.52

For Service two;

We are told that digital streaming costs $8.75 per month. Thus;

Cost = 8.75 * 12

Cost = $105

Step-by-step explanation:

Equilateral triangles are  

always

acute triangles. Yes, because acute is always 60 degrees, and equilateral is basically your average triangle, so its corners have 60 degrees.

Scalene triangles are  

sometimes

acute triangles.      Scalene triangles always dont have that sharp corner..they sometimes do, the sharp turn which is 60 degrees, ACUTE IS ALWAYS 60 DEGREES.

Right triangles are

Answer:  the value of the diversity index D for the population is 0.42

Step-by-step explanation:

Given that; population of the two species are

p1 = 30% = 0.3 (snapping turtle)

p2 = 70% = 0.7 ( box turtle)

so if two (2) organisms are picked, then they can be different from each other ( i.e Event E) under following two scenarios

E1 → First organism selected from p1 and second organism selected from p2

E2 → First organism selected from p2 and second organism selected from p1

which means we are observing the different orders in which the organisms can be picked.

So the probability of event E = the sum of probabilities of events E1 and E2.

which is;

D = P(E) = P(E1) + P(E2)

= P1×P2 + P2×P1

= 2P1P2

so we substitute

D = 2 × 0.3 × 0.7

D = 0.42

Therefore the value of the diversity index D for the population is 0.42

Step-by-step explanation:

It is a 3-4-5 right triangle

The example Option B is False as it is a right triangle with base lengths 3 , 4 and 5

Hence , the example B is not an isosceles triangle

What Is an Isosceles Triangle?

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

The three types of Isosceles Triangles are :

Given data ,

A)

From the figure Triangle A
In this Triangle , the two sides are of equal length and one side is different

So , the triangle is an isosceles triangle

B)

In this triangle , all the three sides are different and it is also a right angled triangle with different lengths

So , the triangle is not isosceles

C)

From the figure Triangle C
In this Triangle , the three sides are of equal length , so it is also an isosceles triangle

So , the triangle is an isosceles triangle

D)

From the figure Triangle D
In this Triangle , the two sides are of equal length and one side is different

So , the triangle is an isosceles triangle

Hence , the example B is not an isosceles triangle and is FALSE

Answer:

They are equal

Step-by-step explanation:

Given

[tex]\frac{3}{27}\ and\ \frac{1}{9}[/tex]

Required

Determine if they are equal

We start by equating both:

[tex]\frac{3}{27} = \frac{1}{9}[/tex]

Cross Multiply

[tex]3 * 9 = 1 * 27[/tex]

[tex]27 = 27[/tex]

Because both sides of the equation are equal, then the ratios are equal

Given:

The graph of an exponential function.

To find:

The function in the form of [tex]f(x)=ab^x[/tex].

Solution:

The general form of an exponential function is

[tex]f(x)=ab^x[/tex]                ...(i)

From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.

For x=0 and f(x)=4,

[tex]4=ab^0[/tex]

[tex]4=a(1)[/tex]

[tex]4=a[/tex]

For x=1 and f(x)=7,

[tex]7=ab^1[/tex]

Putting a=4, we get

[tex]7=4(b)[/tex]

[tex]\dfrac{7}{4}=b[/tex]

Substitute a=4 and [tex]b=\dfrac{7}{4}[/tex] in (i).

[tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex]

Therefore, the required exponential function is [tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex].

Answer:

A shock absorber?

Step-by-step explanation:

Answer:

A) No...

Step-by-step explanation:

We can check if this triangle is a right triangle by using the Pythagorean Theorem.

Using 5 for a, 8 for b, and 12 for c, let's see if this satisfies the equation:

Simplify.

We can see that 89 ≠ 144, so this leaves us with answer choices A and B. I think you meant to write < for the last + sign.

Seeing as the sum of the two lengths of the triangle is greater than the third side length, this creates a normal triangle. This cannot be the correct answer choice since this only satisfies the requirements for a triangle, but not a right triangle.

This leaves us with answer choice A.  52 + 32 ≠ 122 and 52 + 32 < 122. (I'm not sure why the squares of the side lengths are not used, but this should be the correct answer.)
