find the exponential form of 8/27
Explanation:
Note how 8 = 2^3 and 27 = 3^3
This means, 8/27 = (2^3)/(3^3) = (2/3)^3
For the last step, I used the rule (a^c)/(b^c) = (a/b)^c

if the sin of angle x is four fifths and the triangle was dilated to be two times as big as the original, what would be the value of the sin of x for
According to the given statement the value of sin x = 8/10
What is trigonometry?A mathematical field called trigonometry examines connections between triangles' sides and angles. Due to the fact that every straight-sided shape can be decomposed into a group of triangles, trigonometry can be found throughout all of geometry.
How is trigonometry applied in the real world?To roof a home, to make the roof slant (in the case of single-family bungalows), to determine the height of a roof in buildings, etc., use trigonometry. The naval and aviation industries use it. It's applied to cartography (creation of maps). Trigonometry is also used in satellite navigation systems.
According to the given information:sin x = 4/5
We know that:
Sin x = opposite/Hypotenuse.
So,
When the triangle is enlarged, the opposite side will increase to an angle of 8, and the hypotenuse will increase to an angle of 10.
= 4/5 we multiply by 2 with 4 and 5 we get:
= 8/10
4/5 will result from simplifying 8/10. Thus, nothing has changed.
So the value of sin x = 8/10.

Zion Williamson is hoping to be the most dominating freshman that Duke has ever seen on the basketball court. In the first 3 games of the season he has scored 28, 27, and 33 points. To be named one of the best, he has to average at least 36 points a game through 4 games. How many points, p, does he have to score in the 4th game to be named one of the best?
A. ≥ 88
B. ≥ 36
C.
D. > 88
Solve:
please help me
Answer:
greater or equal to 56
Step-by-step explanation:
To have an average of 36 points through 4 games, Zion must score 36x4 (144) points. The first three games added together is 28 + 27 + 33 = 88. 144 - 88 = 56.

Answer:
see attached
Step-by-step explanation:
To plot the line through the point, plot the point. Then find another point that has the given "rise" and "run". Draw the line through the two points.
__
The given point is (-7, -4). Locate that on the graph.
The slope is given as -2/3. This is the ratio of "rise" to "run", so it means the "rise" will be -2 for each "run" of 3. (rise/run = -2/3)
The rise is the vertical change. So, you want your second point to be 2 units below the given point. Its y-coordinate will be -4-2 = -6.
The run is the horizontal change. Your second point will be 3 units to the right of the given point, so its x-coordinate will be -7+3 = -4. Now, you can plot the point (-4, -6) and draw your graph through these two points.

The value is approximate.
==========================================================
Explanation:
Focus on the upper triangle.
Label the unknown horizontal side as y
Use the pythagorean theorem to solve for y
a^2+b^2 = c^2
10^2 + y^2 = 26^2
100+y^2 = 676
y^2 = 676-100
y^2 = 576
y = sqrt(576)
y = 24
-----------
Now move to the bottom triangle
With respect to the reference angle, the side y = 24 is opposite this. The hypotenuse is unknown.
Use the sine rule to connect the two and solve for x
sin(angle) = opposite/hypotenuse
sin(32) = y/x
sin(32) = 24/x
x*sin(32) = 24
x = 24/sin(32)
x = 45.2899179551967 which is approximate
x = 45 rounding to the nearest whole number
Side x is approximately 45 cm long.
Note: make sure your calculator is in degree mode.

m∥n m∠1 = 50°, m∠2 = 48°, and line s bisects ∠ABC What is m∠3 ?
Answer:
m∠3 = 49°
Step-by-step explanation:
From the picture attached,
lines m and n are the parallel lines and line t is a transversal line intersecting these parallel lines at E and B respectively.
Therefore, ∠DEF ≅ ∠ABC [Exterior alternate angles]
m∠1 + m∠2 = m∠4 + m∠5
m∠4 = m∠5 [line s bisects ∠ABC]
50° + 48° = m∠4 + m∠4
98° = 2m∠4
m∠4 = 49°
Since, ∠4 ≅ ∠3 [Vertically opposite angles]
m∠3 = 49°

What is an Algebraic expression?
An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given expression is as below,
1/2 (-1.4m + 0.4) = ?m +0.2
Suppose the unknown number be x.
Then the given expression can be written as,
1/2 (-1.4m + 0.4) = xm + 0.2
=> -0.7m + 0.2 = xm + 0.2
=> -0.7m = xm
=> x = -0.7
Hence, the missing number in the given expression is -0.7.

Using the half-year convention, Calvin may claim 2018 depreciation in the amount of Calvin purchased a new office desk on July 23, 2018, at a cost of $2,373. He did not claim the bonus depreciation deduction. Using the half-year convention, Calvin may claim 2018 depreciation in the amount of ?
Answer:
$339
Step-by-step explanation:
Calculation for the amount of Depreciation that Calvin may claim 2018 Using the half-year convention
Based on the information given we were told that he purchased a new office desk at the amount of $2,373 which means that the new office desk using the half-year convention will be a 7 year property.
Hence,
The Standard Depreciation percentage of the new office desk which is a 7 year property is 14.29% based on this the amount of Depreciation that Calvin may claim 2018 Using the half-year convention will be calculated as:
Using this formula
Depreciation=Cost of new office desk* New office Desk Depreciation percentage
Let plug in the formula
Depreciation=$2,373*14.29%
Depreciation=$339
Therefore Using the half-year convention Calvin may claim 2018 depreciation in the amount of $339

the length of the side x will be 3.61 mm and the length of the side y will be 7.48 mm.
We are given the two right angle triangles.
For the smaller triangle:
Side 1 = 3 mm
Side 2 = 2 mm
Side 3 = x mm
Now, by using the Pythagoras theorem, we get that:
3² + 2² = x²
x² = 9 + 4
x² = 13
x = √13 mm
x = 3.61 mm
For the larger triangle:
Side 1 = 5 mm
Side 2 = y mm
Side 3 = 9 mm
Now, by using the Pythagoras theorem , we get that:
5² + y² = 9²
y² = 81 - 25
y² = 56
y = √56 mm
y = 7.48 mm
Therefore, we get that, the length of the side x will be 3.61 mm and the length of the side y will be 7.48 mm.

Kinda slow on thisss pls help
Answer:
85
Step-by-step explanation:
To solve, use the Pythagorean Theorem, which says c² = a² + b². Enter 84 as a and 13 as b and square them both. This will give you 7056 for a, and 169 as b. Add them to get 7225. So, c² = 7225. Find the square root of this to get 85. So, the third side is 85 in length.
