please help whoever egts right gets brainliest
Answer:24
Step-by-step explanation:
a^2+b^2=c^2
c^2 has to be 26 because it is the hypotinuce. 10 could take the place of a^2 or b^2, it dose not matter.
a^2+10^2=26^2
a^2+100=676
subtract 100 from both sides
a^2=576
sqrt576
a=24
x=a
x=24

How to determine the area of a trapezium?The trapezium is a 2 -dimensional shape consisting of a triangle and a square.
The formula for calculating the area of a trapezoid is expressed as:
Area = 0.5(a + b)h
Area = 0.5(500 + 900) * 800
Area = 700 * 800
Area = 560000 square feet
Since 1 acre is equivalent to 43560 square feet, hence the total acre required is expressed as:
Required acre = 560000/43560
Required acre = 12.856 acres
Also since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

which angle is conterminal with a 645 degree angle
a. an angle measuring 75 degrees
b. an angle measuring 265 degrees
c. an angle measuring 345 degrees
d. an angle measuring 285 degrees
Answer:
D. An angle measuring 285 degrees
Step-by-step explanation:
An angle that is coterminal is congruent to the other angle whether negative or positive or more than 360.
An angle that is 645 degrees can be broken down into 360 + 285.
Since 360 is one revolution the angle would finish with 285 degrees.
Therefore the coterminal angle to 645 is 285.

Step-by-step explanation:
use the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
and therefore also
sin(A)/a = sin(B)/b = sin(C)/c
where the lines and corresponding angles are always opposite of each other.
and remember, the sum of all angles in a triangle is always 180°.
and sin(x) = sin(180-x).
so, we have
sin(32)/43 = sin(B)/53
sin(B) = 53×sin(32)/43 = 0.653156302...
B = 40.77999844...° ≈ 41°
C = 180 - 32 - 40.77999844... = 107.2200016...° ≈ 107°
43/sin(32) = c/sin(107.2200016...)
c = 43×sin(107.2200016...)/sin(32) = 77.507143... ft
≈ 78 ft
B' = 180 - B = 139.2200016...° ≈ 139°
C' = 180 - 32 - 139.2200016... = 8.779998438...° ≈ 9°
43/sin(32) = c'/sin(8.779998438...)
c' = 43×sin(8.779998438...)/sin(32) = 12.38595519... ft
≈ 12 ft

A box contains 3 orange pencils, 9 yellow pencils, and 5 green pencils.
Two pencils are selected, one at a time, with replacement.
Find the probability that the first pencil is green and the second pencil is yellow.
Express your answer as a decimal, rounded to the nearest hundredth.
The probability that the first pencil is green and the second pencil is yellow is 0.16.
What is the probability?Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that the first pencil is green and the second pencil is yellow = (number of green pencils / total number of pencils) x (number of yellow pencils / total number of pencils)
5/17 x 9/17 = 0.16

Which statement is true?
A.

B.
The function is an even function because .
C.
The function is an odd function because .
D.
The function is an even function because its graph is symmetric about the origin.
The true statement is The function f(x)= tan(x) is an odd function because f(-x) = -f(x).
What is odd function?When x is substituted with -x, the odd functions are those that return their negative inverse. When f(-x) = -f(x), it follows that f(x) is an odd function (x). The trigonometric sine function, tangent function, cosecant function, etc. are a few examples of odd functions.
If f(x) = f(x), then the function is odd for all x. An odd function's graph will be symmetrical in all directions around the origin. Consider how unusual f(x) = x³ is. In other words, the function on one side of the x-axis is graphically symmetric about the origin or sign inverted with respect to the other side.
As, we know for the
even function: f(-x) = f(x)
odd function: f(-x)= -f(x)
and, using Trigonometry
tan x = sin x / cos x
Then,
f(-x) = sin (-x) / cos (-x)
= -sin (x) / cos (x)
= -tan (x)
= -f(x)
Thus, tan (x) is an odd function.
Hence, the function f(x)= tan(x) is an odd function because f(-x) = -f(x).

Answer:
a(5) = 1.080
a(10) = 0.393
a(20) = 0.122
Step-by-step explanation:
Take the derivative of velocity v(t) -> acceleration a(t)
v(t) -> a(t)
Quotient Rule: [tex]\frac{u*dv-du*v}{u^2}[/tex]
[tex]120*\frac{x}{5x+13}[/tex]
Make u= 5x+13 and v=x
[tex]120*\frac{x'*(5x+13)-x*(5x+13)'}{(5x+13)^2}\\\\120*\frac{1*(5x+13)-x*(5)}{(5x+13)^2}\\\\120*\frac{(5x+13)-5x}{(5x+13)^2}\\120*\frac{13}{(5x+13)^2} \\\\a(t)=\frac{1560}{(5x+13)^2}[/tex]
Now Subsitute your a(5) , a(10) , a(20). Also, round to 3 decimal place.
a(5) = 1.08033241 = 1.080
a(10) = 0.3930461073 = 0.393
a(20) = 0.122170826 = 0.122
Answer:
(a) 1.080 ft/s²
(b) 0.393 ft/s²
(c) 0.122 ft/s²
Step-by-step explanation:
Acceleration is the derivative of velocity. You are being asked to differentiate the given function and evalutate the derivative at three different times. The function is a rational function, so the formula for the derivative of a ratio is applicable.
(u/v)' = (vu' -uv')/v²
__
For the given velocity function, the accleration is ...
v(t) = (120t)/(5t +13)
a(t) = v'(t) = ((5t +13)(120) -(120t)(5))/(5t +13)² = 1560/(5t +13)²
(a)At t=5, the acceleration is ...
a(5) = 1560/(5·5 +13)² = 1560/1444 ≈ 1.080 . . . ft/s²
(b)At t=10, the acceleration is ...
a(10) = 1560/(5·10 +13)² = 1560/3969 ≈ 0.393 . . . ft/s²
(c)At t=20, the acceleration is ...
a(20) = 1560/(5·20 +13)² = 1560/12729 ≈ 0.122 . . . ft/s²

The equation of the perpendicular line drawn by Leo is [tex]y-G=\dfrac{-1}{2}(x-F)[/tex]. Option C is the correct answer.
The equation of the line is [tex]y-y_1=m(x-x_1)[/tex] where, [tex]m[/tex] is the slope of the line and [tex](x_1,y_1)[/tex] is the point through which it is passing.
How to determine the equation of a line?
A line is drawn perpendicular to the line shown in the image. The perpendicular line passes through the coordinate point [tex](F,G)[/tex].
The slope of the line from the graph is-
[tex]m=\dfrac{y-intercept}{x-intercept}\\=2[/tex]

driven. Colton wants to rent a car, knowing that:
• He plans to drive 275 miles.
• He has at most $450 to spend.
Answer:
5.99 days.
Step-by-step explanation:
If you are asking how many days he can rent the car then this is the correct answer.
So first multiply 275 x .06 to get how much money he will spent on the mileage. Which is $16.50. Then subtract that from $450 which is $433.50 and divided by $72.37.
