Answer:

p=2

Step-by-step explanation:

8n + 16 = 8n + 8p

subtract 8n

16=8p

divide both sides by 8

p = 2

To find the value of p that sets the expression equal to each other:

  ⇒ must set both equations equal to each other, like such:

            [tex]8(n+2)=(n+p)8\\8n+16=8n+8p\\8n+16-8n=8p\\16=8p\\8p=16\\p=2[/tex]

Thus the value of p so that the expression 8(n + 2) is equivalent to (n + p)8​ is 2

Answer: 2

Answer:

7. x = 88

8. x = 59

Step-by-step explanation:

You're probably trying to equal 180° because that's what the triangle should equal so

7. 48° + (88° - 44°) + 88° = 180°

8. 73° + (59° - 11°) + 59° = 180°

I hope this is right :,)

Answer:

8

Step-by-step explanation:

We know that

Equation

[tex] {x}^{2} + {y}^{2} + 2gx + 2fy + c = 0[/tex]

Represents the equation of Circle

where

[tex]radius = \sqrt{ {g}^{2} + {f}^{2} - c } [/tex]

On comparing the given equation with general Equation of Circle

we get

[tex]g = - 5[/tex]

[tex]f = 3[/tex]

[tex]c = - 30[/tex]

On substituting these values We get

[tex]radius = \sqrt{ { (- 5)}^{2} + {3}^{2} - ( - 30) } [/tex]

[tex]radius = \sqrt{25 + 9 + 30 } = \sqrt{64 } = 8[/tex]

[tex]radius = 8[/tex]

This solution is arrived at using the principles of Quadratic Functions and Inequalities. It is to be noted that the function increases at (-8, 4).

A quadratic function can be defined as that is written in the following way: f(x) = ax2 + bx + c: Where a, b, and c are numbers not equal to zero.

To solve the problem f(4x - 3) ≥ f(2 - x^2), Df = (-8 , 4), we:

A) 4x - 3 ≥ 2 - x²

Rewrite as:  x² + 4x - 2 - 3 ≥ 0

B) Collect the like terms

x² + 4x - 5 ≥ 0

C) Expand to have  x² + 5x - x - 5 ≥ 0

D) Factorizing the expression we have

x(x + 5) - 1(x + 5) ≥ 0, from this we  Factor away x + 5

(x - 1)(x + 5) ≥ 0

E) Solving  for x we obtain: x ≥ 1 or x ≥ -5

This can also be rewritten to read:

-5 ≤ x ≤ 1

Hey there!

When multiplying fractions, there is no need to make the denominators the same like how you do when adding fractions

So we can just straight multiply the numerators and the denominators together

[tex]\frac{1}{4}*\frac{3}{1}[/tex]

I made 3 to 3/1 so the multiplying process is easier

3 x 1 is 3 and 4 x 1 is 4

The numerator is 3

The denominator is 4

3/4

So 1/4 x 3 is 3/4

Answer:

the answer for the first one is 141

and the answer for the second is 48

Answer:

First: -1628

Second: -16

Step-by-step explanation:

For the first problem, start by rewriting the equation by plugging in h and g as (4n-3)(-4n-4)

By FOILing this, you’ll end up with -16n^2-16n+12n+12
-16n^2-4n+12

Now you can plug in n, which is -10:

-16(10)^2-4(10)+12

-1600-40+12

-1628

For the second question, you’ll be plugging f(-2) into g, but I’ll leave -2 as n for simplicity until the end

g(n)=n^2+2n

f(n)=2n-4

g(n)=(f(n))^2+2(f(n))

(2n-4)^2+2(2n-4)

(4n^2-16n+16) + (4n-8)

4(-2)^2-16(-2)+16+4(-2)-8

16-32+16-8-8

Step-by-step explanation:

1/2 8 *7 = 28

because there is 4 triangles you do this 28+28+28+28

28+28+28+28 = 112

The lateral surface area of the pyramid is 112 sq. in.

The correct answer is an option (B)

From the attached figure of the net of a square pyramid, we can observe that the side length of the square base is 8 in and height of the lateral triangular face is 7 in.

Hence, The lateral surface area of the pyramid is equal to the area of the four triangular faces of the pyramid.

Using the formula of the area of triangle, the lateral surface area would be,

A = 4 × (1/2 × base × height)

A = 4 × (1/2 × 8 × 7)

A = 4 × (4 × 7)

A = 4 × 28

A = 112 sq. in.

Thus, This is the required lateral surface area.

So, The correct answer is an option (B) 112 in²

Using the exponential distribution, it is found that there is a 0.3297 = 32.97% probability that a randomly selected part will fail in less than 20 hours.

The exponential probability distribution, with mean m, is described by the following equation:

[tex]f(x) = \mu e^{-\mu x}[/tex]

In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.

The probability that x is lower or equal to a is given by:

[tex]P(X \leq x) = \int\limits^a_0 {f(x)} \, dx[/tex]

Which has the following solution:

[tex]P(X \leq x) = 1 - e^{-\mu x}[/tex]

In this problem, the mean and the decay parameter are, respectively, given by:

[tex]m = 50, \mu = \frac{1}{50} = 0.02[/tex].

The probability that a randomly selected part will fail in less than 20 hours is given by:

[tex]P(X \leq 20) = 1 - e^{-0.02 \times 20} = 0.3297[/tex]

0.3297 = 32.97% probability that a randomly selected part will fail in less than 20 hours.
