what is the end behavior of the function?

Answers

The end behavior is that as x approaches positive infinity, f(x) approaches positive infinity and as x approaches negative infinity, f(x) approaches negative infinity

How to determine the end behavior?

The function is given as:

f(x) = 8x+8

The above function is a linear function.

A linear function is represented as:

f(x) = mx + b

This means that the slope of f(x) is 8 (a positive number)

For a linear function with a positive slope, the end behavior is that:

As x approaches positive infinity, f(x) approaches positive infinity and as x approaches negative infinity, f(x) approaches negative infinity

when the positive integer x is divided by 5, the remainder is 3. what is the remainder when X +19 is divided by five

Answers

Answer:

_4

Step-by-step explanation:

x+19/5=3 cross multiply

x+19=3*5

x+19=15

x=15-19

x=-4

The remainder when (x + 19) is divided by 5 is 2.

If the positive integer x has a remainder of 3 when divided by 5, it can be represented as:

x = 5a + 3, where "a" is a non-negative integer.

Now, let's consider the expression (x + 19) and determine the remainder when it is divided by 5:

x + 19 = (5a + 3) + 19

       = 5a + 22

When we divide 5a + 22 by 5, we find:

(5a + 22) = 5(a + 4) + 2

Therefore, the remainder when (x + 19) is divided by 5 is 2.

What is the smallest number of marbles that could be divided up either into bags of $18$ marbles or into bags of $42$ marbles, with no marbles left over in each case

Answers

The number that could be divided up either into bags of 18 marbles or into bags of 42 marbles is 126.

How to find that number?

The number that could be divided up either into bags of 18 marbles or into bags of 42 marbles, with no marbles left over in each case, is the lowest common multiple between these two numbers.

By decomposing these numbers as a product of primes, we get:

18 = 2*3*3

42 = 2*3*7

Notice that the first two prime factors are the same, but the third one changes. To get the first common multiple, we need to multiply both numbers by the third factor (the different one) of the other.

We will get:

18*7 = 126

42*3 = 126

Then 126 is the smallest number that can be divided by 18 and 42.

Triangles

Calculate the perimeter of ABC​

Answers

Answer:

40 units.

Step-by-step explanation:

Consider ∆ADC

Perimeter = 26cm (Given)

★ Perimeter of a triangle is the sum of its three sides.

=> AD + DC + AC = 26

Now, from the figure we can see that side AD = DC

Hence we can also write

=> AD + AD + AC = 26

=> 2AD + AC = 26

=> AC = 26 - 2AD ——— ‘1’

Consider ∆ ABC,

Let us consider it's perimeter to be ‘x’.

=> AB + AC + BC = x

Here also we can make out from the figure that side AB = BC

=> AB + AB + AC = x

=> 2AB + AC = x

From ‘1’ substituting AC value, we get

=> 2AB + ( 26 - 2AD ) = x

=> 2AB - 2AD + 26 = x

=> 2( AB - AD ) + 26 = x

=> 2 (7) + 26 = x ( Given )

Therefore perimeter of the ∆ABC (x) = 40

A box contains 50 batteries, of which 10 are dead and 5 are weak. Suppose you select batteries at random from the box and set them aside for recycling if they are dead or weak. If the first battery you select is dead and the second one is weak, what is the probability that the next battery you select will be weak?

Answers

Probability of selecting 1 dead, 1 weak, then 1 weak = (1/588).

Given: 50 total batteries, of which 10 are dead and 5 are weak. This is represented by: 10/50 (simplifies to 1/5) and 5/50 (simplifies to 1/10).
If the batteries are being set aside, it likely means no replacement. For every battery taken out of the box, the box holds one less battery.

Probability of selecting 1 dead, 1 weak, 1 weak is written as: (10/50)*(5/49)*(4/48) = 1/588.

2(cosx sinx-sinx cos2x)/sin2x =secx

Answers

This is not an identity.

[tex]\dfrac{2(\cos(x)\sin(x) - \sin(x)\cos(2x))}{\sin(2x)} \neq \sec(x)[/tex]

Check x = π/4, for which we have cos(π/4) = sin(π/4) = 1/√2. Together with sin(2•π/4) = sin(π/2) = 1 and cos(2•π/4) = cos(π/2) = 0, the left side becomes 1, while sec(π/4) = 1/cos(π/4) = √2.

Keeping the left side unchanged, the correct identity would be

[tex]\dfrac{2(\cos(x)\sin(x) - \sin(x)\cos(2x))}{\sin(2x)} = -2\cos(x) + 1 + \sec(x)[/tex]

To show this, recall

• sin(2x) = 2 sin(x) cos(x)

• cos(2x) = cos²(x) - sin²(x)

• cos²(x) + sin²(x) = 1

Then we have

[tex]\dfrac{2(\cos(x)\sin(x) - \sin(x)\cos(2x))}{\sin(2x)} = \dfrac{2\cos(x)\sin(x) - 2\sin(x)\cos(2x)}{\sin(2x)} \\\\ = \dfrac{\sin(2x) - 2\sin(x)\cos(2x)}{\sin(2x)} \\\\ = 1 - \dfrac{2\sin(x)\cos(2x)}{\sin(2x)} \\\\ = 1 - \dfrac{2\sin(x)(\cos^2(x) - \sin^2(x))}{2 \sin(x)\cos(x)} \\\\ = 1 - \dfrac{\cos^2(x) - \sin^2(x)}{\cos(x)} \\\\ = 1 - \cos(x) + \dfrac{\sin^2(x)}{\cos(x)} \\\\ = 1 - \cos(x) + \dfrac{1 - \cos^2(x)}{\cos(x)} \\\\ = 1 - \cos(x) + \sec(x) - \cos(x) \\\\ = -2\cos(x) + 1 + \sec(x)[/tex]

Find the value of x y and z​

Answers

Answer:

x = 115° , y = 65° , z = 115°

Step-by-step explanation:

x and 65° are a linear pair and sum to 180°

x + 65° = 180° ( subtract 65° from both sides )

x = 115°

y and 65° are vertically opposite angles and are congruent , then

y = 65°

x and z are vertically opposite angles and are congruent , then

z = x = 115°

CPA is parallel to BPD and so it is also equal to 65 degrees

And all you have to do to find CPB is 180-65=115 and CPB is Parallel to APD thus, its equal to 115 too!

CPA= 65 degrees

BPD=65 degrees

APD= 115 degrees

CPB=115 degrees
