How is the measurement 0.000 065 cm written in scientific notation?
Answers
We have to express 0.000065 cm in scientific notation.
Scientific notation is a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so we can write large numbers using less digits.
Consider 0.000065 cm = cm
Therefore, cm is the scientific notation for the given number 0.000065 cm.

The length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.
What is a circle?
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The arc subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm.
As we know, the relationship between radius of the circle, central angle, and arc length is:
s = rθ
r = 7 cm
θ = 5.4 radians.
When two lines or rays converge at the same point, the measurement between them is called an "Angle."
s = 7×5.4
s = 37.8 cm
Thus, the length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.

x = 7 x= -2
Step-by-step explanation:
x^2 -5x -14 =0
What 2 numbers multiply to -14 and add to -5
-7*2 = -15
-7 +2 = -5
(x-7) (x+2) =0
Using the zero product property
x-7 =0 x+2 = 0
x = 7 x= -2
Answer:
Using the snowflake method, factors that multiply to give -14 and add to give -5 are: 2 and -7.
the factors are: (x+2)(x-7)

the maximum value is achieved when A, D and C are collinear and the quadrilateral ABCD becomes an isosceles triangle ABC
base AB = 52 and vertical angle 2x + 34°
For the sine law
(sin 2x)/22 = (sin ADB)/AB
(sin 34°)/30 = (sin BDC)/BC
is given that AB = BC, and sin ADC = sin BDC because they are supplementary, so from
(sin ADC)/AB = (sin BDC)/BC
it follows
(sin 2x)/22 = (sin 34°)/30
sin 2x = 22 (sin 34°)/30
2x = asin(22 (sin 34°)/30) ≈ 24.2°
x = 0.5 asin(22 (sin 34°)/30) ≈ 12.1°
0 < x < 12.1°
