PLEASE HELP GUYS! 10 POINTS

Answer:

about 32.9

Step-by-step explanation:

By looking at the triangle, you can see that there is both an angle and a side provided. This allows you to use trigonometry (sin, cos, tan). You have to use tan to find the answer since it is used when you have either the opposite side or adjacent side and are solving for one of them. You take the tangent of the angle and set it equal to the opposite over the adjacent (see image attached).

I hope this helps.

Also sorry that the image is the wrong way, but it wouldn't let me attach it the right way.

QUESTION 1

Given a right triangle, the unknown side is opposite to the 35° angle.

The side adjacent to this angle is 47 units.

We use the tangent ratio to get:

[tex] \tan(35 \degree) = \frac{opposite}{adjacent} [/tex]

[tex] \tan(35 \degree) = \frac{x}{47} [/tex]

[tex] x = 47\tan(35 \degree)[/tex]

[tex]x = 32.9units[/tex]

to the nearest tenth.

QUESTION 2

The given angle is 47°

The opposite side is x units.

The adjacent side is 40 units.

We again use the tangent ratio to obtain:

[tex] \tan(47 \degree) = \frac{x}{40} [/tex]

[tex]x = 40\tan(47\degree) [/tex]

[tex]x = 42.9units \: to \: the \: nearest \: tenth[/tex]

Answer:

The length of the line segment is 13 units

Step-by-step explanation:

The line segment joining the two points is horizontal since the y co-ordinate is the same.

For a horizontal line, the length of the line segment is simply the difference between the x co-ordinate values.

In this case we have;

7 - (-6) = 7 + 6 = 13

Therefore, the length of the line segment is 13 units

Answer:

13 units

Step-by-step explanation:

We want to find the length  of the line segment with endpoints (-6,-8) and (7,-8).

Observe that, the y-coordinates are the same.

We can quickly use the absolute value method to find the required length.

According to this method the length of the line segment with endpoints (-6,-8) and (7,-8) is the absolute value of the difference between the x-values.

[tex]|7--6|=|7+6|=|13|=13[/tex]

The length of the line segment is 13 units.

Answer:

( 8.5 , 6.5 )

Step-by-step explanation:

Midpoint formula = ( x₁ + x₂ / 2 ) , ( y₁ + y₂ / 2 )

x₁ = 4

x₂ = 13

y₁ = 10

y₂ = 3

Midpoint = ( 4 + 13 / 2 ) , ( 10 + 3 / 2 )

Midpoint = ( 17 / 2 ) , ( 13 / 2 )

Midpoint = 8.5 , 6.5

Final answer:

The volume of a right circular cylinder with a radius of 3 inches and a height of 10 inches is calculated using the formula V = πr²h, which gives 282.74 cubic inches.

Explanation:

To calculate the volume of a right circular cylinder, you can use the formula V = πr²h, where 'V' is the volume, 'r' is the radius, and 'h' is the height of the cylinder. In this instance, the radius (r) is 3 inches, and the height (h) is 10 inches.

Using these values, you can plug them into the formula:

V = π × (3 in)² × 10 in

V = 3.14159 × 9 in² × 10 in

V = 3.14159 × 90 in³

V = 282.74 in³

Therefore, the volume of the cylinder is 282.74 cubic inches.

Answer:

Step-by-step explanation:

Given

[tex]\frac{x^2-9}{x^2-3x}[/tex]

Factorise the numerator/denominator

x² - 9 = (x - 3)(x + 3) ← difference of squares

x² - 3x = x(x - 3) ← common factor of x

The fraction simplifies to

[tex]\frac{(x-3)(x+3)}{x(x-3)}[/tex] ← cancel (x - 3) on numerator/denominator

= [tex]\frac{x+3}{x}[/tex]

the expressions equivalent to [tex]\(k - \frac{k}{2}\)[/tex] are:

- Option C: [tex]\(\frac{1}{2}k\)[/tex]

- Option D: [tex]\(k + 2\)[/tex]

The correct option is (C) and (D).

the calculation step by step to find expressions equivalent to [tex]\(k - \frac{k}{2}\):[/tex]

1. Given Expression:

 [tex]\[ k - \frac{k}{2} \][/tex]

2. Step 1: Find a Common Denominator:

  To combine the fractions, we need a common denominator. The common denominator for \(2\) and \(1\) is \(2\). So, let's rewrite the expression:

[tex]\[ k - \frac{k}{2} = \frac{2k}{2} - \frac{k}{2} \][/tex]

3. Step 2: Subtract the Fractions:

  Subtract the numerators while keeping the common denominator:

[tex]\[ \frac{2k - k}{2} = \frac{k}{2} \][/tex]

4. Step 3: Simplify:

  Divide the numerator by (2):

[tex]\[ \frac{k}{2} = \frac{1}{2}k \][/tex]

Therefore, the expressions equivalent to [tex]\(k - \frac{k}{2}\)[/tex] are:

- Option C: [tex]\(\frac{1}{2}k\)[/tex]

- Option D: [tex]\(k + 2\)[/tex]

Answer:

72

Step-by-step explanation:

Remember that 9! = 7! (8)(9)

write Substitute

7!(8)(9) for 9!

7!(8)(9)/ 7!= (8)(9)= 72

Answer: 72

Step-by-step explanation:

By definition, it is important to know that the factorial of a non-negative integer "n" is the product of all positive integers less than or equal to "n".  This is expressed with an exclamation symbol (!):

[tex]n![/tex]

Then, the rule for this is the following:

[tex]n! = n *(n-1)![/tex]

Therefore, knowing this, you can evalute [tex]\frac{9!}{7!}[/tex] as following:

 [tex]\frac{9*8*7*6*5*4*3*2*1}{7*6*5*4*3*2*1}=\frac{362,880}{5,040}=72[/tex]

B

Answer: Option A: A vertical line that the line of the graph aproaches but never intecepts it.

Step-by-step explanation:

An asymptote is a graph line that aproaches infinitely to something (in this case a vertical line), but it does not touch it (so never intercepts the graph).

This means that the graph aproaches but never intercepts the line, so the correct answer is A.

Answer:

Option C is correct.

Step-by-step explanation:

P(A or B) represents  that event A has occurred or event B has occurred or both events A and B are happening.

We are given P(A or B) = 0.60 or 0.60/100 = 60%

So, Option C The probability that a customer buys either a taco or a drink is 60% is correct.

Answer: Option C

Step-by-step explanation:

For two events A and B, P(A or B) represents the probability that event A occurs, or event B occurs.

In this case, event A represents a customer buys a taco and event B represents a customer buys a drink. We know that

[tex]P (A\ or\ B) = 0.60[/tex]

So this means that the probability that a customer buys either a taco or a drink is 60%

The answer is the option C

We are looking for the number of pencils per hour.

[tex]0.178571428571 \frac {penc} {g} * 64,512 \frac {g} {h} = 11,520 \frac {pen} {h}[/tex]

Answer:

[tex]m=0.002kg[/tex]

Step-by-step explanation:

The given formula is:

[tex]E=mc^2[/tex]

Divide both sides by [tex]c^2[/tex].

[tex]\implies \frac{E}{c^2}=\frac{mc^2}{c^2}[/tex]

Cancel out the common factors to get;

[tex]\implies \frac{E}{c^2}=m[/tex]

[tex]m=\frac{E}{c^2}[/tex]

When [tex]E=1.8\times10^{14}J[/tex] and [tex]c=300,000,000ms^{-1}[/tex], then

[tex]m=\frac{1.8\times10^{14}}{300,000,000^2}[/tex]

This simplifies to

Answer:

-8/5

Step-by-step explanation:

The thing that makes lines different from other kinds of curves is their constant rate of change. We call this rate of change slope, and you usually see it represented with the letter m. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.

We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate increases by 5, while our y-coordinate decreases by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as

m = -8/5

Answer:

-3

Step-by-step explanation:

In order to find the smallest zero, we will have to find out all the zeros of the function.

In case you are wondering what a zero is, it is the x-value or the domain intersections. The points where the parabola intersects the x-axis.

4x² - 8x - 60 = 0

Why zero?

We know that the parabola intersects the x-axis and when it does, the y-value is 0. h(x) is nothing but 'y'.

4(x²-2x-15) = 0 → I took the gcd as 4 and did it accordingly.

x² - 2x - 15 = 0 → Divide on both sides with 4

Now, what multiples to -15 but adds up to -2?

-5 and 3

x² + 3x - 5x - 15 → Grouping the terms

x ( x + 3 ) - 5 ( x + 3 ) → Taking the GCD in both groups

( x - 5 ) ( x + 3 ) = 0

x = 5 , -3

The smallest one out of these zeros is -3.

Answer:

Neither function A nor function B has an x-intercept.

Step-by-step explanation:

Function A has a y-intercept at (0, 5).

Function B is defined for negative numbers as well as positive numbers, but not for x=0.

These observations eliminate all answer choices but the first one.

The statement that best compares the two functions is; Neither function A nor function B has an x-intercept.

A y-intercept is the point where x = 0. Now, for function A we can see that when x = 0, y = 5. Thus, it has a y-intercept.

However, we are not given the point where y = 0 which is x-intercept. Thus, function A does not have an x-intercept.

Formula for Function B is y = 4/x.

This function does not have an x-intercept because at x = 0, the function is undefined.

Given  : x³ + 2x² +x +2.

To find :  complete factorization of the polynomial below.

Solution : We have given x³ + 2x² +x +2.

On taking common x² from first two terms and 1 from last two terms .

x² ( x +2) +1 (x +2).
