Answer:
The gradient of 
is 
.
Step-by-step explanation:
Geometrically speaking, the gradient of a curve is the slope of the tangent line at a given point of the curve. From perspective of Differential Calculus, the gradient is the first derivative of the curve. Let , then the gradient of the curve is:
(1)
The gradient of is .
Answer:
6 to the power of one sixth.
Step-by-step explanation:
Cube root of 6 = 6^(1/3) and the square root of this = [ 6^(1/3) ]^1/2
= 6^(1/3 * 1/2)
= 6^(1/6).
Answer:
25/36
Step-by-step explanation:
(2^-1 + 3^-1)^2
➡
➡
(1/2 + 1/3)^2
➡
(5/6)^2 = 25/36
Answer:
2*√2
Step-by-step explanation:
You need to use the trigonometrical function of angle (You should use the side sqrt2 and x to find the x). Take any acute angle (for example, 60 degrees)
The cos of this angle is equal to the ratio of adjoined leg (sqrt2) to the hypotenude (the side opposite to right angle, it is x)
cos60degrees= sqrt2/ x
1/2= sqrt2/x
x= 2*sqrt2= 2*√2
The lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.
<h3>Algebra</h3>
- Cost of higher-priced speaker = $170
- Cost of lower-priced speaker = $80
- Number of lower-priced speaker = 4x
- Number of higher-priced speaker = x
Higher-priced speaker = 170 × x
= 170x
Lower-priced speaker = 80 × 4x
= 320x
Total sales = $4,410
170x + 320x = 4,410
490x = 4,410
divide both sides by 490
x = 4,410 / 490
x = 9
So,
Number of lower-priced speaker = 4x
= 4 × 9
= 36
Number of higher-priced speaker = x
= 9
Therefore, the lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.
