X = 14
1/2 of 14 = 7
7 + 13 = 20
This will be easier to write, and a lot easier to read, if we temporarily
use another symbol ... say, 'Q' ... to represent ' sin(2x) ' .
Here we go:
Original equation: Q² - 0.5 Q = 0
Factor the left side: Q (Q - 0.5) = 0
This equation is true if either factor is zero:
-- If Q=0, then sin(2x) = 0
2x = 0°, 180°, 360°
x = 0°, 90°, 180°
-- If (Q-0.5) = 0, then Q = 0.5
sin(2x) = 0.5
2x = 30°, 150°
x = 15°, 75°
The whole collection of solutions
between 0° and 360° :
x = 0°, 15°, 75°, 90°, 180° .
Answer:
I figure that the answer is 1.6 because to find a, you do 24 divided by 15.
Answer:
40
Step-by-step explanation:
SO im guessing if its the full graph one box counts 1.
So the top side counts 8
The left one is 15
The perimeter means adding all the sides together.
We already have 2. But finding the hypotenuse would not be easy from graph so we will use Pythagorean theorem.
a^2+b^2=c^2
8^2+15^2 = c^2
64+225 = c^2
289 = c^2
c = 17
so the perimeter is 8+15+17 = 40
Answer:
The correct option is A.
Step-by-step explanation:
The given graph sh a shows scatter plot and linear model of Joanna's height, in inches, for various ages.
From the given graph it is noticed that the linear line passing through the points (0,30) and (2,35).
The slope of the linear model is
The slope of linear model is 2.5, it means the Joanna can expect her height to increase about 2.5 inches every year.
Therefore option A is correct.
