Hi!
The Desmos graph is below.
According to the graph, we can see that one of the points is (1, -5).
<u><em>Additional information:</em></u>
In inequalities, each equation will be <u>shaded</u> a certain direction/side, and anything in that shaded region is a solution to the equation. With 2 inequalities, the solutions to the equations will be in the <u><em>double-shaded</em></u> region.
Also, inequalities will either have a <u>dotted</u> (- - - - -) line or a <u>solid</u> (───) line. You will use a <em>dotted</em> line for inequality equations with <em>></em><em> or </em><em><</em><em> symbols, </em>and <em>solid</em> lines for inequality equations with <em>≥</em><em> and </em><em>≤</em><em> symbols.</em>

Question:
Complete question for this is to find the equation for this and may be the graph.
Explanation:
As for the oscillation motion, initially peak is occurring hence it will be a cosine function with peak value of 3(cm).
To calculate time period, the whole cycle should be 360°
i.e.
cos (Xπ.t) = cos (360)
as the cycle completes at 1.2 sec hence by putting t=1.2, answer should be 360.
i.e.
X*180*t=360
X*180*1.2=360
X=5/3
So, the required equation is
Graph for this equation is attached here with this answer.
In graph,
x-axis: t=0 ~ t=1.2
y-axis: f(x)=-4 ~ f(x)=4
Step-by-step explanation:
the circumference of a circle is
2×pi×r
with r being the radius, which is always half of the diameter.
r = 1.8 / 2 = 0.9 cm
circumference :
2×pi×0.9 = 1.8×pi = 1.8 × 3.142 = 5.6556 cm ≈ 5.7 cm
Answer:
x = - 4, x = 0, x = 1
Step-by-step explanation:
To find the zeros equate p(x) to zero, that is
3x³ + 9x² - 12x = 0 ← divide through by 3
x³ + 3x² - 4x = 0 ← factor out x from each term
x(x² + 3x - 4) = 0
x(x + 4)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x = 0
x + 4 = 0 ⇒ x = - 4
x - 1 = 0 ⇒ x = 1
