Step-by-step explanation:
[tex]2.3+0.02\left(x+20\right)-4.8=-9[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}100[/tex]
[tex]2.3\cdot \:100+0.02\left(x+20\right)\cdot \:100-4.8\cdot \:100=-9\cdot \:100[/tex]

To divide the function f(x) by (x2-4x-12), we find that the quotient is Q(x) and the
remainder is (x+6). If f(-2)=a and f(6)=b, what is the value of b/a?
Answer:
b/a = 3
Step-by-step explanation:
f(x) / (x²-4x-12) = Q(x) + (x+6)/(x²-4x-12)
f(x) = Q(x)*(x²-4x-12) + (x+6)
x= - 2 ... when f(x) is f(-2) x²-4x-12 = 4+8-12 = 0
a = f(-2) = Q(x)*0 + (-2 + 6) = 4
x= 6 ... when f(x) is f(6) x²-4x-12 = 36-24-12 = 0
b = f(6) = Q(x)*0 + (6 + 6) = 12
b/a = 12/4 = 3
If 90° < θ < 180° and cscθ = 3, then cotθ = _____.
[tex]\text{Given that,}\\\\\csc \theta = 3\\\\\implies \csc^2 \theta = 9\\\\\implies 1+ \cot^2 \theta = 9\\\\\implies \cot^2 \theta = 8\\\\\implies \cot \theta = \pm \sqrt 8 = \pm 2\sqrt 2\\\\\text{Since,}~90^{\circ}< \theta < 180^{\circ},\\\\\cot \theta = -2\sqrt 2[/tex]
Determine the center of the ellipse whose equation is.
Answer:
It is reported as an equation but it has no equal sign.
Care to explain?
Step-by-step explanation:
Answer:
(4, -3) is the center
Step-by-step explanation:
The equation ...
16x^2 +25y^2 -128x +150y +81 = 0
can be rearranged by completing the square(s) to ...
(4x -16)^2 +(5y +15)^2 = 400
Dividing by 400 gives ...
(x -4)^2/5^2 +(y +3)^2/4^2 = 1
This is the equation of an ellipse centered at (4, -3) with major axis 10 and minor axis 8.

A 15 kg ball is thrown into the air. It is going at 4m/s when thrown. How much potential energy will it have at the top?
Answer:
P.E = mgh = 120N
Step-by-step explanation:
v² = u² - 2as
At the top, the velocity is = 0
0² = 4² - 2 x 10 x s
4² = 20s
s = 16/20
s = 0.8metres.
It rose only 0.8metres.
Therefore P.E = 15 x 10 x 0.8
:. P.E = 15 * 8
:. P.E = 120N
