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:

( 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 )

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

Answer:

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]

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

Answer: [tex]x=7[/tex]

Step-by-step explanation:

By the Intersecting Secants Theorem, we know that:

Having this, we can find the value of "x" by solving for "x":

Applying Distributive property:

[tex](5)(x+5)=(6)(24)\\5x+25=60[/tex]

Subtract 25 from both sides of the equation:

[tex]5x+25-25=60-25\\5x=35[/tex]

First of all, you have to send the measurements; otherwise, there would not be an answer

Question 1:

Substitution.

x+y=2

y=-x+2

2x+(-x+2)=4

x=2

(2)+y=2

y=0

Solution: (2,0)

There is one solution

Question 7 is too confusing, just find where the points intersect at (-5,2).

Question 9:

Elimination.

(-1)y=2x+6

y=2x+2

New: -y=-2x-6

0=-4

No Solution

Question 11:

Just look at explanations.

It's (5,17) both lines etc..

Final answer:

The set of equations for Line A and Line B has one solution. The graph correctly represents the solution (-5, 2) if the lines intersect 5 units to the left and 2 units up. Equations C and D have no solution since the lines are parallel, and the solution to Lines C and D is (5, 17), with both lines passing through this point.

Explanation:

Question 1: To determine the relationship between Line A: x + y = 2 and Line B: 2x + y = 4, we can solve for y in both equations.

For Line A, y = 2 - x.

For Line B, y = 4 - 2x.

Since the coefficients of x are different in the two equations, and the y-intercepts are also different, the lines are not parallel nor identical. Therefore, they intersect at exactly one point, which means there is one solution to the set of equations.

Question 7: The coordinates of the solution is given as (-5, 2). Among the options, the one showing the lines intersecting at the point 5 units to the left and 2 units up represents the correct set of lines, so the graph that corresponds to this description contains the solution.

Question 9: Comparing the two equations: Equation C: y = 2x + 6 and Equation D: y = 2x + 2, we see that both have the same slope but different y-intercepts. Because they have the same slope but different y-intercepts, these lines are parallel and never intersect. Hence, there is no solution to this set of equations.

Question 11: To find the intersection point, we set the equations of Line C: y = x + 12 and Line D: y = 3x + 2 equal to each other and solve for x:

x + 12 = 3x + 2

Subtract x from both sides: 12 = 2x + 2

Subtract 2 from both sides: 10 = 2x

Divide by 2: x = 5

We then substitute x = 5 into one of the equations to find y:

For Line C: y = 5 + 12 = 17.

Hence, the solution to the set of equations is (5, 17), and both lines pass through this point, which lies between the two axes, but that is irrelevant to why it is the solution.

The equation of the circle will be ( x + 1 )² + ( y - 1 )² = 9.

All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

The equation of the circle can be written as,

( x - h)² + ( y - k )² = r².

Given that the circle below is centered at (-1, 1) and has a radius of 3. The equation of the circle will be written as,

( x - h)² + ( y - k )² = r².

( x + 1 )² + ( y - 1 )² = 9.

Hence, the equation can be written as ( x + 1 )² + ( y - 1 )² = 9.

5x^5•y^2 + 15x^2•y^3 + x^3•y^5

GCF = (x^2)(y^2)

The greatest common factor of the given polynomial is x²y².

The GCF (Greatest Common Factor) of two or more numbers is the greatest number among all the common factors of the given numbers. The GCF of two natural numbers x and y is the largest possible number that divides both x and y without leaving any remainder.

The given expression is 5x⁵y²+15x²y³+x³y⁵.

In the given expression, there are three terms 5x⁵y², 15x²y³ and x³y⁵

5x⁵y²=5×x×x×x×x×x×y×y

15x²y³=3×5×x×x×y×y×y

x³y⁵ =x×x×x×y×y×y×y×y

So, the common factor = x×x×y×y

= x²y²

Therefore, the greatest common factor is x²y².

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
