-5x + 12 - 7x = -3(5x + 8)
Answer:
x = -12
Step-by-step explanation:
-5x + 12 - 7x = -3(5x + 8)
-5x + 12 - 7x = -15x - 24
-12x + 12 = -15x - 24
-12x + 15x = -24 - 12
3x = -36
x = -12
I need help trying to find the trig function for this problem
9514 1404 393
Answer:
x ≈ 136.7 ft
Step-by-step explanation:
As you have marked, the relevant sides are the adjacent side and the hypotenuse. The mnemonic SOH CAH TOA reminds you ...
Cos = Adjacent/Hypotenuse
For this triangle, that means ...
cos(43°) = (100 ft)/x
x = (100 ft)/cos(43°) . . . . . . . . . . multiply both sides by x/cos(43°)
x ≈ 136.73 ft
The length x is about 136.7 feet.

A circle with center point N and three points A, B, C on its circumference. A line is drawn connecting the points A, N and C and the angle ANC is given as 138 degree.
A. 111°
B. 138°
C. 222°
D. 276°
9514 1404 393
Answer:
138°
Step-by-step explanation:
The measure of arc ABC is the measure of the corresponding central angle, ∠ANC. That angle is shown as 138°, so the measure of arc ABC is 138°.
Measure of an angle ABC is 111 degrees i.e. [tex]m[/tex]∠ABC = 111 degrees.
Angle subtended by an Arc of a circle-Theorem
The angle subtended by an arc at the center of the circle is double the angle subtended by the same arc at the circumference of the circle.
According to the given question
The angle subtended at the center of circle, i.e. ∠ANC = 138 degrees.
The exterior angle at the center is (360 - 138)degrees = 222 degrees
by angle subtended by an Arc of a circle theorem
[tex]m[/tex]∠ABC = [tex]\frac{222}{2}[/tex] [tex]= 111 degrees[/tex]
Hence, [tex]m[/tex]∠ABC = 111 degrees.

Una persona camina 7 kilómetros hacia el norte, después 3 kilómetros hacia el este y, luego, 3 kilómetros hacia el sur. ¿A qué distancia está del punto de partida
Answer:
La persona está a 5 kilómetros con respecto al punto de partida.
Step-by-step explanation:
Considérese que la dirección norte coincide con el semieje +y y que la dirección este coincide con el semieje +x. A continuación, obtenemos las formas vectoriales equivalentes de cada afirmación:
(i) Una persona camina 7 kilómetros hacia el norte:
[tex]\vec r_{1} = 7\,\hat{j}\,[km][/tex]
(ii) Después 3 kilómetros hacia el este:
[tex]\vec r_{2} = 3\,\hat{i}\,[km][/tex]
(iii) Y luego, 3 kilómetros hacia el sur:
[tex]\vec r_{3} = -3\,\hat{j}\,[km][/tex]
El vector resultante de desplazamiento se construye a partir de la siguiente suma de vectores:
[tex]\vec R = \vec r_{1}+\vec r_{2} + \vec r_{3}[/tex] (1)
[tex]\vec R = 3\,\hat{i} + 4\,\hat{j}\,[km][/tex]
Asumiendo que la distancia coincide con el desplazamiento resultante, calculamos la distancia con respecto al punto de partida mediante el Teorema de Pitágoras:
[tex]\|\vec R\| = \sqrt{3^{2}+4^{2}}[/tex]
[tex]\|\vec R\| = 5\,km[/tex]
La persona está a 5 kilómetros con respecto al punto de partida.

The denominator of the first term is a difference of squares, such that
4a ² - b ² = (2a)² - b ² = (2a - b) (2a + b)
So you can write the fractions as
(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)/(2a + b)
Multiply through the second fraction by 2a - b to get a common denominator:
(4a ² + b ²)/((2a - b) (2a + b)) - (2a - b)²/((2a + b) (2a - b))
((4a ² + b ²) - (2a - b)²) / ((2a - b) (2a + b))
Expand the numerator:
(4a ² + b ²) - (2a - b)²
(4a ² + b ²) - (4a ² - 4ab + b ²)
4ab
So the original expression reduces to
4ab / ((2a - b) (2a + b))
or
4ab / (4a ² - b ²)
upon condensing the denominator again.

The height in ft of a rocket after x seconds is given by y=128-16x^2y. What is the maximum height reached by the rocket, and how long does it take the rocket to reach max height.
Answer:
Max height = 128feet
Time = 0secs
Step-by-step explanation:
Given the height in ft of a rocket after x seconds is given by y=128-16x^2, at maximum height, the velocity of the object is zero that is;
dy/dx = 0
0 - 32x = 0
x = 0/-32
x = 0
Hence the time taken for the object to reach its maximum height is 0 secs
To get the maximum height reached, you will substitute x = 0 into th expression given as shown;
y = 128 - 16x^2
y = 128 - 16(0)^2
y = 128 - 0
y = 128feet
Hence the maximum height reached by the rocket is 128feet

Answer:
91 rad/s
Step-by-step explanation:
The relationship between angular velocity (ω) and constant angular acceleration (ω') is ...
ω(t) = ω0 + t·ω'
ω(0.25) = 95 = ω0 + 0.25(16)
95 -4 = ω0 = 91 . . . rad/s
The initial angular speed was 91 radians per second.

Step-by-step explanation:
[tex] \tan(26) = \frac{42}{x} \\0.487732588565 \times x = 42 \\ x = 86.11276134633[/tex]
C.x=86.113
Answer:
C (86.113)
Step-by-step explanation:
First, find the missing angle B. Since angles in a triangle add upp to 180,
180-26-90= 64
Then use the formula a/sina = b/sinb
' a' in the formula is the missing length X and sina is the corresponding(opposite) angle of X which is sin64.
B in the formula would be 42 and sinb is sin26 (the angle).
Substitute all values into the formula,
X/sin64 = 42/ sin26
Shift sin64 to the right side:
X= 42(sin64)/ sin26
X= 86.113
Hope this makes sense:)
