What is Descarte's rule of signs in a polynomial?Descarte's rule for no. of at most positive real roots in a polynomial is the no. of sign changes in the polynomial.
Descarte's rule for no. of at most negative real roots in a polynomial f(x) is the number of sign changes in f(-x).
All the other left over roots are imaginary and come in conjugate pairs.
The number of negative of f is equal to the number of sign changes of successive terms of f(-x).
Given, g(x) = 3x² + 14x - 5.
Now, g(-x) = 3(-x)² + 14(-x) - 5.
g(-x) = 3x² - 14x - 5.
The signs are +, -, - so only one sign changes.

A triangular pyramid has a volume of 48 in3. The base edge is 9 in and the base height is 4 in. Find the height of the pyramid.
Answer:
8 in
Step-by-step explanation:
First of all we have to find the area of the base triangle.
For do this we can use this formula:
A = (base edge x base height)/2
A = (9 x 4)/2 = 18 in^2
The formula for find the volume of a pyramid is:
V= Base area x height)/3
So the height can be find in this way
3 x V = base area x height
height = (3 x V)/base area
height = (3 x 48)/18 = 8 in
Answer:
pretty sure it is 8in I think

the linear function g is defined by g(x)=4x. show that g(3) and g(2) have a difference of 4.
Answer:
the answer is D.
Step-by-step explanation:
well, the y-intercept for f(x) is at
as you can see from the slope-intercept form is at 4, and it has an slope of 2/3.
for g(x), well an y-intercept is when x = 0, what is it from that table? well, is at 0,3, so when x = 0, y = 3, so no dice on that one.
c)
whenever an x-intercept occurs, y = 0, for f(x) that's at
what about the x-intercept for g(x)? well, let's check, when is y = 0? aha! at -9, 0, so when y = 0, x = -9, so no dice on that one either.
d)
well, what is the slope of g(x) anyway? well, let's pick two points off the table to get it hmmm the first two let's use,
and from a), using the slope-intercept form, we know f(x) has a slope of 2/3.
well, 2/3 is larger than 1/3, so no dice.
b)
well, you already know.

A car uses 1 liter of gas every 12 kilometers. How many meters can the car travel on 3 liters of gas? 36 meters 3,600 meters 360 meters 36,000 meters
Answer:
36,000 meters. 12km= 12,000m multiply by 3l of gas.
Step-by-step explanation:
The car will travel 36000 meters using 3 liters of gas as per linear equation.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, 'A' is a coefficient and 'B' is constant".
Given, a car uses 1 liter of gas every 12 kilometers.
Therefore, using 3 liters of gas, the car will go
= 3 × 36 kilometers
= 36 kilometers
= 36000 meters
With 3 liters of gas, the car will travel 36000 meters.

The triangular prism shown below is 6 \,\text{cm}6cm6, start text, c, m, end text wide and 4\,\text{cm}4cm4, start text, c, m, end text deep. The vertical height is 7\,\text{cm}7cm7, start text, c, m, end text. What is the length of the side edge, sss, of the triangular prism?
Answer:
The answer is "7.62 cm ".
Step-by-step explanation:
Given:
[tex]Width = 6\ cm \\\\Depth = 4 \ cm\\\\Vertical \ height = 7 \ cm\\\\[/tex]
Dividing the prism's face into two halves:
As just a result, the vertical height becomes 7cm, as well as the width, becomes [tex]\frac{6\ cm}{2} = 3 \ cm[/tex]. If the 's' on both sides of the edge is equal:
[tex]s^2 = width^2 + height^2\\\\[/tex]
[tex]= \sqrt{(width^2 + height^2)}\\\\[/tex]
[tex]= \sqrt{(3^2 + 7^2)}\\\\= \sqrt{9 + 49}\\\\= \sqrt{58}\\\\= 7.62 \ cm[/tex]

Solve:3x+3y=27 and its algebra
Answer: X=9-y
Step-by-step explanation:
Answer:
x = 9 - y
y = 9 - x
Step-by-step explanation:
Solving for X:[tex]3(x + y) = 27[/tex]
[tex]x + y = \frac{27}{3} [/tex]
[tex]x + y = 9[/tex]
[tex]x = 9 - y[/tex]
Solving for Y:[tex]3(x + y) = 27[/tex]
[tex]x + y = \frac{27}{3} [/tex]
[tex]x + y = 9[/tex]
[tex]y= 9 - x[/tex]
Hence, the answer for x is x = 9 - y and the answer for y is y = 9 - x.

Answer:
1. ∠1 = 120°
2. ∠2 = 60°
3. ∠3 = 60°
4. ∠4 = 60°
5. ∠5 = 75°
6. ∠6 = 45°
Step-by-step explanation:
From the diagram, we have;
1. ∠1 and the 120° angle are corresponding angles
Corresponding angles are equal, therefore;
∠1 = 120°
2. ∠2 and the 120° angle are angles on a straight line, therefore they are supplementary angles such that we have;
∠2 + 120° = 180°
∠2 = 180° - 120° = 60°
∠2 = 60°
3. Angle ∠3 and ∠2 are vertically opposite angles
Vertically opposite angles are equal, therefore, we get;
∠3 = ∠2 = 60°
∠3 = 60°
4. Angle ∠1 and angle ∠4 an=re supplementary angles, therefore, we get;
∠1 + ∠4 = 180°
∠4 = 180° - ∠1
We have, ∠1 = 120°
∴ ∠4 = 180° - 120° = 60°
∠4 = 60°
5. let the 'x' and 'y' represent the two angles opposite angles to ∠5 and ∠6
Given that the two angles opposite angles to ∠5 and ∠6 are equal, we have;
x = y
The two angles opposite angles to ∠5 and ∠6 and the given right angle are same side interior angles and are therefore supplementary angles
∴ x + y + 90° = 180°
From x = y, we get;
y + y + 90° = 180°
2·y = 180° - 90° = 90°
y = 90°/2 = 45°
y = 45°
Therefore, we have;
∠4 + ∠5 + y = 180° (Angle sum property of a triangle)
∴ ∠5 = 180 - ∠4 - y
∠5 = 180° - 60° - 45° = 75°
∠5 = 75°
6. ∠6 and y are alternate angles, therefore;
∠6 = y = 45°
∠6 = 45°.
