Find a degree 3 polynomial with real coefficients having zeros 3 and 4 i and a lead coefficient of 1. Write P in expanded form. Be sure to write the full equation, including P ( x ) = .
Answer:
[tex]P(x)=x^3-3x^2+16x-48[/tex]
Step-by-step explanation:
Given information:
Polynomial function with real coefficients.Zeros: 3 and 4iLead coefficient of 1.For any complex number [tex]z=a+bi[/tex], the complex conjugate of the number is defined as [tex]z^*=a-bi[/tex].
If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.
Therefore, if P(x) is a polynomial with real coefficients, and 4i is a root of f(x)=0, then its complex conjugate -4i is also a root of P(x)=0.
Therefore, the polynomial in factored form is:
[tex]P(x)=1(x-3)(x-4i)(x-(-4i))[/tex]
[tex]P(x)=(x-3)(x-4i)(x+4i)[/tex]
Expand the polynomial:
[tex]P(x)=(x-3)(x^2+4ix-4ix-16i^2)[/tex]
[tex]P(x)=(x-3)(x^2-16(-1))[/tex]
[tex]P(x)=(x-3)(x^2+16)[/tex]
[tex]P(x)=x^3+16x-3x^2-48[/tex]
[tex]P(x)=x^3-3x^2+16x-48[/tex]

Eleanor and Luke started on a trip to the mountains with their six-year old car. Their
odometer read 87,236.2 miles at the start of the trip and 87,626.2 miles at the end of the trip.
They used 14.5 gallons of gas on the trip. How many miles per gallon did they achieve with
their car?
They achieved 26.9 miles per gallon approximately with that car in this trip.
Given that the initial odometer reading is = 87236.2 miles
Final odometer reading after trip is = 87626.2 miles
So the distance of the total trip is = 87626.2-87236.2 = 390 miles
They used 14.5 gallons of gas on the tri[p.
So the mileage is = 390/14.5 = 26.9 miles per gallon approximately.

Answer:
42 rotten tomatoes would likely be found in 14 boxes.
Step-by-step explanation:
Since [tex]\frac{12}{4} = \frac{3}{1}[/tex] , there are 3 rotten tomatoes in every box.
[tex]\frac{3 * 14}{1 * 14} = \frac{42}{14}[/tex]

write in slope-intercept form the equation of a line which passes through (4,1) with a slope of 1/2
The equation of the line which passes through (4, 1) in slope - intercept form is y = 1/2x - 1
How to find the equation of the line?The equation of a line takes the form:
y = Slope (x) + y - intercept
The slope is already given as 1 / 2 and we have a point on the line. This point can be substituted into the equation of a line to find the value of the y - intercept.
y = Slope (x) + y - intercept
1 = 1/2 (4) + y - intercept
y - intercept = 1 - 2
y - intercept = - 1
The equation of the line will then be:

Lesbian Anna close cylinder have the same radius the height of the cylinder is four times the radius what is the ratio of the volume of the cylinder to the volume of the sphere
The ratio of the volume of the cylinder to the volume of the sphere = 3:1
Let take the volume of a closed cylinder as V1.
And take the volume of a closed sphere as V2.
And the radius of the cylinder = radius of the sphere = r
Height of the cylinder = h
If height of the cylinder is four times the radius of the cylinder which means h = 4r
Volume of the closed cylinder V1 = π × r^2 × h
if h = 4r
Then V1 = π × r × r × 4r
V1= 4π × r^3
Volume of the closed cylinder V1= 4π × r^3
Volume oh the sphere V2 = 4/3 × π × r^3
The ratio of the volume of the cylinder to the volume of the sphere
= V1 / V2 = V1 : V2
V1 : V2 = (4π × r^3) ÷ (4/3 × π × r^3)
V1 : V2 = 4 ÷ 4/3 = 4/1 × 3/4 = 3/1 = 3 : 1

A triangle has vertices at A(-2,3,) B(2,1) and C(1,0) after a transformation the image of the triangle has vertices at A(-2,-3) B(2,-5) and C(1,-6) identify the transformation
The transformation is applied to ΔABC to get the ΔA'B'C' is vertical translation of 6 units downwards.
The triangle has the vertices A(-2, 3), B(2, 1), and C(1, 0)
They are transformed such that:
A(-2, 3)→A'(-2,-3)
B(2, 1)→B'(2,-5)
A(-1, 0)→A'(-2,-6)
Now, if we pay close attention, we can notice that A's y-coordinate is 6 less than A's.
Similar to A, B and C have coordinates that are 6 units lower than the object's coordinates but with the same x-coordinate.
This demonstrates that the graph undergoes a vertical translation; the graph is translated 6 units lower since the new ordinates are 6 units smaller.
A transformation, or f: X→X', is a function that maps to itself. The transformation will result in the pre-image X becoming the image X'. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, may be used in this transformation.

8. Given that the total distance travelled is 1.4 km, and the
acceleration is 4 m/s² for the first T seconds, find:
a) the value of V
b) the value of T.
Step-by-step explanation:
Formula for distance travelled:
x= ut + 1/2at^2
x is 1.4km, convert this to m since acceleration is in m, = 1400m
u is initial velocity, in this case assume 0
a is acceleration, = 4m/s^2
t is unkown and what we want to find out
Substitute value into formula,
1400 = 0t + 1/2(4)t^2
1400 = 2t^2
t^2 = 1400/2
t^2 = 700
t = 26.458s
Formula for acceleration:
a = (v-u)/t
at= v-u
Substitute value,
4(26.458) = v - 0
v = 105.832 m/s

Answer:
f(x) = -3x+1
Step-by-step explanation:
every straight graph has an equation f(x) = m * x + b
when the graph goes up when you look at it from left to right, m is a positive number. when it goes down, then m is negative.
the value of m you can read when you go 1 to the right and then count how many you need to go up/down to meet the graph. in this picture, you need to go down 3.
So m = -3
b is how many you habe to go up (+) or down (-) from the center point 0
so in this case you see on the picture that the graph is hitting the y line on 1
so your equation is -3x + 1

How to get the resulting equation?
Given:
{x² + y² = 25
{x²/16 - y²/9 = 1
Zach isolated x² in the first equation, we have:
x² + y² = 25
x² = 25- y²
Zach then substituted the x² into the second equation:
x²/16 - y²/9 = 1 (put x² = 25- y²)
(25- y²)²/16 - y²/9 = 1 (Expand the bracket)
(625- 50y²+y⁴)/16 - y²/9 = 1 The LCM of 9 and 16 is 144
( 9(625- 50y²+y⁴) - 16 y² ) /144 = 1 Cross multiply

The Singapore Navy acquired 4 Swedish- build Sjoormen class submarine to beef up its defence capabilities in the late 1990s. The submarine is capable of attaining a top speed of 16 knots (nautical miles per hour) when submerged. Convert 16 knots to (a) km/h (b) m/s. (Take 1 nautical mile to be 1 853 m.)
The speeds when converted are 29.648 km/h and 8.24 m/s
How to convert the units of speed?From the question, we have the following parameters that can be used in our computation:
Speed = 16 knots
Also, from the question, we have
1 nautical mile to be 1853 m
This means that
Speed = 16 * 1853 m per hour
Convert meters to kilometers
So, we have
Speed = 16 * 1.853 km per hour
Evaluate the products
Speed = 29.648 km/h
Also, we have
Speed = 16 * 1853 m per hour
Convert hour to seconds
So, we have
Speed = 16 * 1853/3600 m/s
