8(5 – 2x)
need help answering this question
Let's simplify this problem using the distributive property.
The first thing we want to do is change the minus to plus a negative.
Now distribute or multiply the 8 times
each of the terms inside the set of parentheses.
So we get 8(5) + 8(-2x) and this simplifies to 40 + -16x.

cual es la longitud del alambre que sostiene un poste de 8 m de altura , si dicho alambre esta amarrado al suelo a 4m del poste
Answer:
La longitud del alambre que sostiene el poste es 8.94 metros.
Step-by-step explanation:
La longitud del alambre se puede calcular usando Pitágoras:
[tex] L^{2} = P^{2} + B^{2} [/tex]
En donde:
L: es la longitud del alambre =?
P: es la altura del poste = 8 m
B: es la distancia del alambre al poste = 4 m
Entonces, la longitud del alambre es:
[tex] L = \sqrt{P^{2} + B^{2}} = \sqrt{(8 m)^{2} + (4 m)^{2}} = 8.94 m [/tex]
Por lo tanto, la longitud del alambre que sostiene el poste es 8.94 metros.

find the value of each variable using sine and cosine. round your answers to the nearest tenth
Answer:
x=9.5 and y=15.3
Step-by-step explanation:
to find x you do sine of 32 = x/18 because the sine is opposite/hypotenuse
you put in a calculator sine (32) x 18 and get 9.538546756
so x equals 9.538546756 but it says to round to the nearest tenth so x equals 9.5
to find y you do the cosine of 32 = y/18 because cosine is adjacent/hypotenuse
cosine of (32) x 18 = 15.26486573 so you equals 15.26486573 but since you have to round to the nearest tenth y = 15.3
The value of x is 9.54.
The value of y is 15.3.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
From the figure,
Sin 32 = x / 18
Cos 32 = y / 18
Now,
Sin 32 = 0.53
Cos 32 = 0.85
Now,
0.53 = x / 18
Multiply 18 on both sides.
x = 0.53 x 18
x = 9.54
0.85 = y / 18
Multiply 18 on both sides.
y = 0.85 x 18
y = 15.3
Thus,
The value of x is 9.54.
The value of y is 15.3.

What is the value of z in the equation 2(4z − 3 − 1) = 166 − 46?
I know that 166-46 is 120 but i get stuck on the distributive property part. I end up with 8z-2. Also I will give brainliest.
Answer:
2(4z − 3 − 1) = 166 − 46
8z − 6 − 2 = 120
8z − 8 = 120
8z = 128
z = 16
pls give the brainliest
Step-by-step explanation:
Answer:
Step-by-step explanation:
you have to multiply 2(4z - 3 - 1 ). so 2 * 4z = 8z. so then you would do 2 * (-3) = -6. then you would do the same with -1. 2* (-1) = -2.
now you have to put it back in equation form. 8z - 6 - 2 = 166 - 46. now you have to combine like terms. -6-2 = -8. 166 - 46 = 120. and then put it back into equation form. 8z - 8 = 120. then you add 8 to 120. 120+8 = 128. now to find z all you have to do is divide 128/8 = 16
z = 16

What is the x- value of the midpoint between A (-8,-6) and B (0, 6)?
Answer:
Step-by-step explanation:
Take average of the x-coordinates of A and B.
(-8+0)/2 = -4
x-coordinate of midpoint = -4
The required x value of the midpoint between A(-8, -6) and B (0, 6) is -4.
Given that,
To determine the x value for the midpoint between A (-8,-6) and B (0, 6).
Coordinate, is represented as the values on the x-axis and y-axis of the graph. Where x coordinate of the graph is called an abscissa and y coordinate of the graph is called ordinate.
The midpoint is that point of the line which has an equal distance from both ends of the line.
the x value of the midpoint between A(-8, -6) and B (0, 6) is given by,
x = ( x1 + x 2) / 2
x = ( - 8 + 0 ) / 2
x = - 8 / 2
x = - 4
Thus, the required x value of the midpoint between A(-8, -6) and B (0, 6) is - 4.

suppose that the population of deer in a state is 16,000 and is growing 1%each year Predict population after 6 years
Answer:
16984
Step-by-step explanation:
Given
[tex]a = 16000[/tex] ---- Initial
[tex]r = 1\%[/tex] --- rate
Required
Determine the population after 6 years
To do this, we make use of the following exponential function
[tex]f(x) = a(r+1)^x[/tex]
Substitute values for a and r
[tex]f(x) = 16000(1\%+1)^x[/tex]
Express 1% and decimal
[tex]f(x) = 16000(0.01+1)^x[/tex]
[tex]f(x) = 16000(1.01)^x[/tex]
The population after 6 years is:
Substitute 6 for years
[tex]f(6) = 16000(1.01)^6[/tex]
[tex]f(6) = 16984.3224096[/tex]

Answer:
The remaining piece measures 16 m
which agrees with answer D
Step-by-step explanation:
In order to make a square of area 25 m^2, we need a square of side 5 m ,
Area of square = side^2
25 = side^2 then each side = 5 m
therefore the person needed 4 times 5 m to create the square, that is 20 m for the square. Therefore the piece that is left can be calculated with the difference:
36 m - 20 m = 16 m
The remaining piece measures 16 m
a ball has a volume of 2 cubic inches .use the fact that l inch is equal to 2.54 cm to convert this volume to cubic centimeters
Answer:
32.77 cm³
Step-by-step explanation:
From the question given above, the following data were obtained:
Volume of ball (in in³) = 2 in³
Volume of ball (in cm³) =.?
From the question given above, we were told that:
1 in = 2.54 cm
Therefore,
1 in³ = 2.54³ cm³
Finally, we shall convert 2 in³ to cm³. This can be obtained as follow:
1 in³ = 2.54³ cm³
Therefore,
2 in³ = 2 in³ × 2.54³ cm³ / 1 in³
2 in³ = 32.77 cm³
Thus, 2 in³ is equivalent to 32.77 cm³
