Which of the following is a root of the polynomial function below?
F(x)= x³ +3x² - 5x-4

Answer:

not enough information given

Step-by-step explanation:

as the rules say, we need at least 3 pieces of information :

2 angles and a side, or 3 angles (or there are other options like 2 sides and one angle or 3 sides).

but here we get 1 side and 1 angle. the shared point does not give us anything in that regard.

so, not enough information.

The following statements are true:

A negative number in mathematics is any number that is less than zero i.e. x < 0.

This means that zero is greater than any negative number.

However, the higher the digit of a negative number, the smaller that number becomes. It is opposite of positive numbers or integers.

Irregular pentagon since it has 5 sides

Answer:

irregular pentagon

Step-by-step explanation:

This shape still has five sides--making it a pentagon. Because the angles are not exactly the same, and so the side lengths are also not equal, we name it an "irregular" pentagon.

Using a system of equations, it is found that a value of h = 4 will result in an infinite number of solutions.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

If two equations are equal, the system has infinite solutions.

In this problem, the equations are:

4x - 16 = h(x - 4).

Then:

4(x - 4) = h(x - 4).

h = 4.

Answer: Parallel lines have equal slopes

If the slope of line s is -32 or -3/2, then the same applies to line t

Parallel lines have equal slopes but different y intercepts. These lines do not cross or intersect.

Answer:  -32

Step-by-step explanation:

The two lines are parallel which means these two lines have the same slope. Therefore, the slope of line t is -32.

Answer:

z = 30

Step-by-step explanation:

→ 360 ÷ z = 12

→ 360/z = 12

→ 12z = 360

→ z = 360/12

→ [ z = 30 ]

Hence, the value of z is 30.

Answer:you have to isolate z,make z the subject.

Step-by-step explanation: z=360 multiply by 12,

giving us 4320.z=4320,i mean thisis the answer you have to stick with if u want to find a value for z.

step by step;z/360=12

z=360 into 12

z=4320

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the legs a, b and the hypotenuse c, often called the Pythagorean equation:[1]

[tex]a^{2}+b^{2}=c^{2},[/tex]

Create a diagram of the scenario first. You would have a right triangle with a hypotenuse (longest side) of h + 4, a longest leg of h - 68, and one leg of length h to represent the pole.

Set up the equation [tex]h^2 + (h - 68)^2 = (h + 4)^2[/tex] using the Pythagorean theorem ([tex]a^2 + b^2 = c^2[/tex]).

[tex]h^2 + (h - 68)^2 = (h + 4)^2[/tex]

On simplifying we get

[tex]h^2+h^2-136h+4624 = h^2+8h+16[/tex]

[tex]2h^2-136h+4624=h^2+8h+16[/tex]

[tex]h^2-144h+4608=0[/tex]

Solving using quadratic formula

[tex]h_{1,\:2}=\frac{-\left(-144\right)\pm \sqrt{\left(-144\right)^2-4\cdot \:1\cdot \:4608}}{2\cdot \:1}[/tex]  

[tex]h_1=\frac{-\left(-144\right)+48}{2\cdot \:1},\:h_2=\frac{-\left(-144\right)-48}{2\cdot \:1}[/tex]

h1 = 96 feet , h2 = 48 feet

If height would have been 48 feet then the other side would have a negative value as as 48 - 68 = -20 .

Hence the height of the pole is 96 feet

Answer:

x = 40

Step-by-step explanation:

All angles in a triangle add up to 180

(3x-10) + 30 + x = 180

4x = 160

x = 40

Answer: x = 40

Step-by-step explanation:

All the interior angles of a triangle add up to 180°

Therefore,

30 + 3x - 10 + x = 180

30 + 4x - 10 = 180

20 + 4x = 180

4x = 160

x = 40

First, 0.0004853 is < 1, so we need to multiply the number by 10 to a negative power if it's greater than 1 (if that makes sense i cant describe it better)

So, b and c is incorrect.

10 to the power of negative 4 = 0.0001, and 4.853 x 0.0001 = 0.0004853 (true), so answer is a

Answer:

a

Step-by-step explanation:

a number expressed in standard form is

a × [tex]10^{n}[/tex]

where 1 ≤ a < 10 and n is an integer

to place the decimal point in its original position we require to shift it 4 places left , denoted by - 4 on the exponent , that is

Answer:

A) 384

B) 576

Step-by-step explanation:

the area of a rhombus is

pq/2

First Rhombus

we have p but to find q we can cut the triangle in half to form a right triangle, that allows us to use the Pythagorean theorem

20² = 12² + b²

400 - 144 = b²

b² = 256

b = 16

since the height (b) is half the rhombus, we double it to get q

p = 24

q = 32

a = [tex]\frac{24*32}{2}[/tex]

a = 384

Second Rhombus

Since rhombuses are parallelograms, we can use its area formula  (b)(h)

a = (24)(24)

a = 576

The set of values which might correspond to the circle are A = 1, B = 1, C = 0, D = -8 and E = 7.

Mathematically, the general form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

Based on the information provided that the center of the circle lies on the y-axis, we have:

(h, k) = (0, 4)

Radius, r = 3 units.

Substituting the given parameters into the formula, we have;

(x - 0)² + (y - 4)² = 3²

x ² + y² - 8y + 16 = 9

A normal distribution can be used to approximate a binomial distribution when n* p and n * q are greater than 5.

A probability distribution that is symmetric about the mean is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean.

A probability bell curve is more properly described as the normal distribution.

The mean and standard deviation of a normal distribution are 0 and 1, respectively. It has a kurtosis of 3 and zero skew.

Not all symmetrical distributions are normal, but all normal distributions are symmetrical.

Natural occurrences frequently resemble the usual distribution.
