Answer:
fraction
Step-by-step explanation:
If you have a negative exponent, such as [tex]x^{-2}[/tex], that can also be written as [tex]\frac{x^{-2} }{1}[/tex]
by moving the exponent (and it's base) to the denominator (the other side of the fraction, since it's in the numerator), you make the exponent positive: [tex]\frac{1}{x^{2} }[/tex]

Can someone help me on #7 and #9? It is to find x and y in a parallelogram. Thanks! Will give 12 points.
how do you know you have a direct variation in the relationship between two quantities?
Answer:
Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.

5n = 41 Divide both sides by 5
n = 8 1/5
An airplane is flying at a height of 200m. Its angle of elevation to an observer on the ground is 230. Calculate the distance of the airplane from the observer.
Answer:
Distance between the plane and the observer is 511.86 miles.
Step-by-step explanation:
From the figure attached,
A plane is flying at point A which is at 200 m height and observer is at point C.
Angle of elevation (∠ACB) of the plane from the observer is 23°.
Let the distance between the observer and the plane is x meters.
By applying sine ratio for angle C,
sin(∠C) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(23°) = [tex]\frac{200}{x}[/tex]
x = [tex]\frac{200}{\text{sin}(23)}[/tex]
x = 511.86 miles
Therefore, distance between the plane and the observer is 511.86 miles.

This triangle has one side that lies on an extended line segment. Based on this triangle, what statement about x is true? A. x = 27 because 180−109−44=27 B. x = 65 because 109−44=65 and 44 + 65 = 109 C. x = 71 because 180−109=71 D. x = 153 because 109 + 44 = 153 and 153−44=109
MEASUREMENTS (down below)
A triangle with base on an extended line. Two angle measures are given. Top interior angle is forty-four degrees. Lower right exterior angle is one hundred nine degrees. Lower left interior angle is labeled x degrees.
Answer:
B. x = 65 because 109−44=65 and 44 + 65 = 109
Step-by-step explanation:
Given :
The triangle below :
Sum of interior angles of a triangle :
(44° + x + (180 - 109) = 180°
44° + x + 71° = 180
115° + x = 180°
x = 180° - 115°
x = 65°

What is the degree of the polynomial? 5x^5 - 6x^6 + 2
Answer:
6
Step-by-step explanation:
Degree of a polynomial is the degree of the monomial with the greatest degree, which in this case is 6x^6, so the degree of this polynomial is 6 because the x is raised to the 6th degree.
The degree of the polynomial 5x⁵-6x⁶ + 2 is 6.
What is a polynomial?An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Given:
The polynomial,
5x⁵-6x⁶ + 2.
Here, we have the variable x.
And the highest power of a variable is a degree of a polynomial.
So, the degree of polynomial is 6.
Therefore, the degree of the polynomial is 6.

Find each length
5. the length of the hypotenuse of a 45 degree- 45 degree- 90 degree triangle with a leg of 12
6. the length of the longer leg of a 30 degree- 60 degree- 90 degree triangle with a hypotenuse of 14, where theta = 60 degrees
Answer:
12√2
7√3
Step-by-step explanation:
The length of the hypotenuse of a 45°-45°-90° triangle with a leg of 12 is 12√2 and the length of longer leg is 7√3 for 30°-60°-90° triangle.
What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
Ratio of the sides of a 45°-45°-90° triangle is 1 : 1 : √2.
That is,
If sides opposite to 45° = x, then the side opposite to 90° = √2 x
That is, length of the hypotenuse = √2 x
Given length of a leg = 12
Length of the hypotenuse = √2 × 12 = 12√2.
Ratio of the length of sides of 30°-60°-90° triangle is 1 : √3 : 2.
That is,
Length of side opposite to 30° = x
Length of side opposite to 60° = √3 x
Length of side opposite to 90° = 2x (Hypotenuse)
We have to find the longer leg, that is √3 x.
Length of hypotenuse = 14
2x = 14 ⇒ x = 7
Length of longer leg = 7√3
Hence the lengths are 12√2 and 7√3.

At a bake stall there is a large square pan of chocolate brownies. Customers can buy any fraction of the pan of brownies they like.The first customer bought 1/2 of the pan of brownies. The second customer bought 5/6 of what was left of the pan of brownies. What fraction of the whole pan did the second customer buy
Answer: 5/12
Step-by-step explanation:
Since the first customer bought 1/2 of the pan of brownies. This means that the pan of brownies left will be:
= 1 - 1/2
= 1/2
The The second customer bought 5/6 of what was left of the pan of brownies, the fraction that the second customer bought will be:
= 5/6 × 1/2
= 5/12
Answer:
5/12
Step-by-step explanation:
At a bake stall there is a large square pan of chocolate brownies. Customers can buy any fraction of the pan of brownies they like.
The first customer bought 1/2 of the pan of brownies.
The amount of brownies that was left over is given as:
1 - 1/2 = 1/2 brownies left ove
The second customer bought 5/6 of what was left of the pan of brownies.
The amount of brownies the second customers bought is calculated as:
5/6 of 1/2
= 5/6 × 1/2
= 5/12

Considerate of these three numbers express and scientific notation 8.2×10 to the -3rd power 5.2×10 to the $96 and 4.1 times since I'm -6 hours which number is the greatest invite how many times does it rather than smallest number
Answer:
[tex]8.2 * 10^{-3}[/tex] is the greatest
2000 times greater
Step-by-step explanation:
Given
[tex]8.2 * 10^{-3}[/tex]
[tex]5.2 * 10^{-6}[/tex]
[tex]4.1 * 10^{-6}[/tex]
Solving (a): The greatest of the numbers
First, we convert them to decimals:
[tex]8.2 * 10^{-3} = 0.0082[/tex]
[tex]5.2 * 10^{-6} = 0.0000052[/tex]
[tex]4.1 * 10^{-6} = 0.0000041[/tex]
By comparing the decimal numbers, the highest is: 0.0082.
Hence,
[tex]8.2 * 10^{-3}[/tex] is the greatest
Solving (b): How many times greater than the smallest
In (a) above:
The greatest is: [tex]8.2 * 10^{-3}[/tex]
By comparing the decimal numbers,
The smallest is: 0.0000041 i.e. [tex]4.1 * 10^{-6}[/tex]
The number of times the greatest is greater than the smallest is:
[tex]Number = \frac{8.2 * 10^{-3}}{4.1 * 10^{-6}}[/tex]
[tex]Number = \frac{0.0082}{0.0000041}[/tex]
[tex]Number = 2000[/tex]
Hence, it is 2000 times greater

Need answer ASAP I’m timed What is the distance between the points (7, 8) and (-8, 0) on a coordinate grid?
Answer:
17
Step-by-step explanation:
(7, 8) (-8, 0)
First find how much the point moved in y to the second point.
8-0=8
So one side is 8.
Then find how much it moved in x. 7-(-8)=15
So the other side is 15
This will give you 2 sides of a triangle where one sides lenght is 8 the other is 15. Use the pythagoras theorem which is x squared plus y squared = c squared
8^2+15^2=c^2
64+225=c^2
289=c^2 Take the square root of both sides to solve for C
√289= √C^2
17 = c
