the answer is 3^5 because multiplication is done by adding the carriers
Answer:
x = 5
Step-by-step explanation:
Rewrite the equation
3^x+2=2187
perform prime factorization of the right side
2187=3^7
3^x+2 = 3^7
equate the exponents of 3 on both sides
x+2 = 7
solve for x
x=5
What is the Rotational speed of someone standing in Helsinki, Finland located at 60°11' N and 24°56' E.? (radius of the earth is 3960 miles)
Answer:
515.5 mph
Step-by-step explanation:
I am fairly confident we are taking the same test/quiz thing right now and I figured this one out so here ya go:
60 degrees + 11 sec = 60.183 degrees
3960 * cos(60.183) = 1969 some number in relation to the distance to the poles
2 * pi * 1969 = 12371.8
12371.8 / 24 = 515.5mph
look up "How to Calculate Rotational Speed Around Earths Axis" on YT, video is by " VAM! Physics & Engineering" that is where I found the formula stuffs

If sin theta= 4/5 and theta is in quadrant 2, the value of cot theta is . if necessary, use the slash mark ( / ) for a fraction bar.
If sin θ= 4/5 and theta is in quadrant 2, the cot θ would be -3/4.
Which trigonometric functions are positive in which quadrant?
In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.
In second quadrant(π/2 < θ < π), only sin and cosec are positive.
In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.
In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.
Given information; If sin θ= 4/5 and theta is in quadrant 2, we need to find the value of cot theta.
Since it’s in second quadrant, cos is going to be negative.
So, a^2 + 4^2 = 5^2
a^2 + 16 = 25
a^2 = 25 - 16 = 9
a = 3
therefore, we can conclude that cos θ = base / hypotenuse
cos θ =-3/5
Also, tan θ would be -4/3 and then cot θ would be -3/4.

Express the product of (2x + 3) and (x - 5)
Answer:
Here is the answer......
Answer:
2x² - 7x - 15
Step-by-step explanation:
Given
(2x + 3)(x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x - 5) + 3(x - 5) ← distribute parenthesis
= 2x² - 10x + 3x - 15 ← collect like terms
= 2x² - 7x - 15

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Answer:
Step-by-step explanation:
First choose two points on the line,
Let the points are A and B.
From point A to B we are moving downwards by (5 - 1 = 4 units)
Therefore, Rise = -4
Horizontal distance between A and B = 2 units
Therefore, Run = 2
Since, slope of a line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Slope = [tex]\frac{-4}{2}[/tex]
= -2

Answer:
12(4) +6
48+6 = 54
y=54
Step-by-step explanation:
Step-by-step explanation:
Given function: y = 12x + 6
Input: x = -4
Replacing the value of x in function y,
y = 12 x (-4) + 6
y = -48 + 6
y = -42

describe how to use special product patterns to find 21^2
Answer:
21 x 21 = 441
Step-by-step explanation:
Whenever there is an exponent that is the many times you multiply the base by itself to.
Power is the result of multiplying two numbers together. The value of 21^2 is 441.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
Given that 21 has a power of 2, therefore, 21 to the power 2 means that 2 should be multiplied by itself twice.
21^2
= 21²
= 21 × 21
= 441
Hence, the value of 21^2 is 441.

Answer:
The answer is 9.
Step-by-step explanation:
Hey there, so it looks to me that you just have to subsitute 2 in for x, and solve the equation. Like this.
1. Plug in X: 3(2)^2 -2(2) + 1
2. Solve exponents (2)^2 = 4, so the equation is 3(4) - 2(2) + 1
3. Multiplication: 3 × 4 = 12, and -2 × 2 = -4, so the equation is 12 - 4 + 1
4. Addition: -4 + 1 = -3, so it is now 12-3
5. Subtraction: 12-3 = 9, so the answer is 9!
