Given function
f(x)=x⁴−x³−2x−4Factoring the polynomial
x⁴−x³−2x−4 = (x⁴−4) − (x³+2x) =(x² + 2)(x² - 2) - x(x² + 2) =(x² + 2)(x² - x - 2) =(x + i√2)(x - i√2)(x - 2)(x + 1)As we see there are 2 complex factors

A conical water tank with vertex down has a radius of 11 feet at the top and is 20 feet high. If water flows into the tank at a rate of 10 ft3/minft3/min, how fast is the depth of the water increasing when the water is 12 feet deep?
Answer:
0.073 ft/min
Step-by-step explanation:
The radius of the tank = 11 feet and the height of the tank = 20 feet. The depth of water = h = 12 feet, let r be the radius of the water, hence:
[tex]\frac{r}{h}=\frac{11}{20}\\ \\r=\frac{11}{20}h\\ \\The \ volume\ of\ the \ tank\ is:\\\\V = \frac{1}{3} \pi r^2 h=\frac{1}{3}\pi (\frac{11}{20}h)^2.h=\frac{121}{1200}\pi h^3 \\\\Given\ that\ rate=\frac{d}{dt}(V)= 10ft^3/min\\\\\frac{dV}{dt}= \frac{d}{dt}( \frac{121}{1200}\pi h^3)\\\\\frac{dV}{dt}=\frac{121}{1200}\pi (3h^2\frac{dh}{dt})\\\\\frac{dV}{dt}=\frac{121}{400}\pi h^2(\frac{dh}{dt})\\\\Given\ water\ is\ 12ft\ deep, i.e.\ h=12.Substituting:\\\\[/tex]
[tex]10=\frac{121}{400}\pi (12^2)\frac{dh}{dt} \\\\\frac{dh}{dt} =0.073\ ft/min[/tex]
g A spotlight on the ground is shining on a wall 20m away. If a woman 2m tall walks from the spotlight toward the building at a speed of 0.8m/s, how fast is the length of her shadow on the building decreasing when she is 4m from the building
Answer:
0.3 m/s
Step-by-step explanation:
[tex]\dfrac{dx}{dt}=\text{Speed of person}=0.8\ \text{m/s}[/tex]
As the two triangles in the diagram are similar to each other we have
[tex]\dfrac{y}{12}=\dfrac{2}{8}\\\Rightarrow y=12\times \dfrac{2}{8}\\\Rightarrow y=3\ \text{m}[/tex]
Again as the triangles are similar we have
[tex]\dfrac{y}{2}=\dfrac{12}{12-x}\\\Rightarrow x=12-\dfrac{24}{y}[/tex]
Differentiating the above equation with respect to time we get
[tex]\dfrac{dx}{dt}=\dfrac{-24\times-1}{y^2}\dfrac{dy}{dt}\\\Rightarrow \dfrac{dy}{dt}=\dfrac{dx}{dt}\times\dfrac{y^2}{24}\\\Rightarrow \dfrac{dy}{dt}=0.8\times \dfrac{3^2}{24}\\\Rightarrow \dfrac{dy}{dt}=0.3\ \text{m/s}[/tex]
The speed at which the shadow is changing is 0.3 m/s.

If ĐPQR = 50°, what is the measure of its complement?
Answer:
The measure of its complement is 40°
Step-by-step explanation:
The sum of the measures of the complementary angles is 90°If the measure of an angle is x°, then the measure of its complement is 90° - x°∵ The measure of angle PQR equal 50 degrees
∴ m∠PQR = 50°
∵ Angle x is the complement angle of angle PQR
→ That means the sum of the measures of angle x and angle PQR is 90°
∴ m∠x + m∠PQR = 90
→ Substitute measure of angle PQR by 50°
∴ m∠x + 50 = 90
→ Subtract 50 from both sides
∴ m∠x + 50 - 50 = 90 - 50
∴ m∠x = 40°
∴ The measure of its complement is 40°
Find equation with points (-3,-8) and (1, 16)
Answer:
The equation of the line is y = 6x + 10.
Step-by-step explanation:
(-3,-8) (1 ,16)
x1, y1. x2,y2
Gradient(m) = (y2 - y1)/(x2 - x1)
= (16 - (-8))/(1 - (-3))
= 24/4 = 6
Equation of a line is given as:
(y - y1) = m(x - x1)
y - (-8) = 6(x - (-3))
y + 8 = 6x + 18
y = 6x + 10
All the factors of 200 and all the factors of 300 are factors of 600. True or false and explain.
Answer:
true because 200 and 300 are factors of 600
Step-by-step explanation:
Answer:
I don't think so
Step-by-step explanation:
600 is a composite number.
Prime factorization: 600 = 2 x 2 x 2 x 3 x 5 x 5, which can be written 600 = (2^3) x 3 x (5^2)
The exponents in the prime factorization are 3, 1 and 2. Adding one to each and multiplying we get (3 + 1)(1 + 1)(2 + 1) = 4 x 2 x 3 = 24. Therefore 600 has exactly 24 factors.
Factors of 600: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
Factor pairs: 600 = 1 x 600, 2 x 300, 3 x 200, 4 x 150, 5 x 120, 6 x 100, 8 x 75, 10 x 60, 12 x 50, 15 x 40, 20 x 30 or 24 x 25
Taking the factor pair with the largest square number factor, we get √600 = (√100)(√6) = 10√6 ≈ 24.494897. (Note: 2 + 4 = 6 and 49 + 48 = 97 so this square root and √6 can be easy to remember.)

In a direct variation, y = 16 when x = 4. Write a direct variation equation that shows the
relationship between x and y.
Write your answer as an equation with y first, followed by an equals sign.
In a direct variation, y = 16 when x = 4. The direct variation equation shows the relationship between x and y will be y=4x.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
y = 16 when x = 4
There are often two different sorts of variables in analytics. We obtained that independent variables will have an impact on dependent variables. What occurs as a result of the independent variable is referred to as a dependent variable.
In the given equation x is the independent variable while y is the dependent variable.
16 = 4(4)
y=4x
Thus, in a direct variation, y = 16 when x = 4. The direct variation equation shows the relationship between x and y will be y=4x.
