Integer refers a collection of whole numbers and negative numbers.
Given,
Here we have the integer N.
And we need to find the following:
a. the smallest possible value of N if N >= 6.5
b. the largest possible of N if N < -3
c. the possible values of N if N >= -2 and N <2.
Part a). smallest possible value of N if N >= 6.5
Here the smallest number is 6.5 because other value are greater than this one.
Part b). the largest possible of N if N < -3
The largest possible number is -2, because the other values on N are less than -2.
Part c). the possible values of N if N >= -2 and N <2.
Here the possible values between these are {-2, -1, 0, 1}.

Epsilon3 is an exoplanet with a mass of 9.43x10^27g. It has a radius of 7.6x10^8cm. What is the density of the planet? What is it made of?
The density of the planet is 4.81 g/cm^3, and with this in mind, we assume that the planet is made of titanium or yttrium.
How to get the density of the planet?Density is defined as the quotient between mass and volume.
Here we know that the mass is:
9.43*10²⁷g
And the radius is 7.6x10^8cm, remember that the volume of a sphere of radius R is:
V = 3.14*(3/4)*R³
Then in this case the volume is:
V = 3.14*(3/4)*(9.43*10⁸ cm)³ = 1.96*10²⁷ cm³
Then the density is:
D = (9.43*10²⁷g)/(1.96*10²⁷ cm³) = 4.81 g/cm^3
For this density, we can assume that the planet is made of Titanium or Yttrium (or a combination of a lot of elements like most planets)

Alexi like her drink to have a ratio of liquid yo ice of 1 to 3. A fat food retaurant put 16 oz of ice in her 32 oz cup
Alexi will not like the drink because the ratio of liquid to ice is 1/1.
Alexi likes her drink to have a liquid-to-ice ratio of about 1/3. A fast food restaurant put 16 ounces of ice in her 32-ounce cup. We need to find out if Alexi will like her drink or not, and if not, why not.
Let the ratio of the liquid to the ice in the drink be represented by the variable "R". The total volume of the cup is 32 ounces. The amount of ice in the cup is 16 ounces. So the amount of liquid in the drink is the difference between these two amounts. Hence, the amount of liquid in the cup is 32 - 16 = 16 ounces.
The ratio of the amount of liquid to the amount of ice in the drink is calculated below.
R = 16/16
R = 1/1
Hence, the ratio of the amount of liquid to the ice in the drink is 1/1. So, Alexi will not like her drink.

A city planner wants to build a road perpendicular to d street. What should be the slope of the new road?.
If a line's angle with the x-axis is then, that line's slope will be tanα, and the new road's slope will be tan(0) = 0.
D Street is depicted as a vertical line with a 90° angle of inclination in the accompanying figure. In other words, D Street has an infinite slope.
The new road will therefore have 0° of inclination if it is perpendicular to D street because if they are perpendicular and D street is vertical, the new road is level and has 0° of inclination.
A horizontal line now has zero slopes.

Rhino poaching is a serious problem and has resulted in rhinos, particularly the black rhino, becoming an endangered species. Statistics suggest that there were 60 500 black rhinos at the beginning of 1970, but only 4 000 remained at the end of 2011. Determine the annual rate of depreciation that these statistics represent.
The annual percentage rate of depreciation of the number of rhinos represented by the statistics is approximately 6.41 %
What is a rate of depreciation?The rate of depreciation is the rate at which the number or value of an item reduces within each specified period.
The initial number of black rhinos in 1970 = 60,500
The number of black rhinos remaining in 2011 = 4,000
The annual rate of depreciation can be found using the formula;
[tex]FV = PV \cdot \left(1+\dfrac{r}{100} \right)^n[/tex]Where;
FV = The future value = 4,000
PV = The present value = 60,500
r = The annual depreciation rate
n = The number of years
[tex]4,000 = 60,500 \times \left(1+\dfrac{r}{100} \right)^{(2011-1970)}=60,500 \times \left(1+\dfrac{r}{100} \right)^{41}[/tex]
[tex]\left(1+\dfrac{r}{100} \right)^{41} = \dfrac{4000}{60500} = \dfrac{8}{121}[/tex]
[tex]r = 100\times \left(\sqrt[41]{ \dfrac{8}{121}} - 1\right) \approx -6.41[/tex]

Answer:
Can't be solved
Step-by-step explanation:
Using Pythagoras theorem,
H2= O2 + A2 (where, H= Hypotenuse,O=Opposite,A=Adjacent)
The hypotenuse,H=7feet long
If the opposite side of the triangle is 4 feet longer than the adjacent side, then;
O=A+4
while, A=A
,then using H^2= O^2 + A^2(The 2 are power,that is square)
7^2 = (A+4)^2 + A^2
49= (A+4)(A+4) + A^2
49=A^2 +4A+4A+16 + A^2
49=A^2+8A+16+A^2
(collect like terms)
49-16=A^2+A^2+8A
33=2A^2+8A
Then a quadratic equation,
2A^2+8A=33
2A^2+8A-33=0,

where b=8, a=2, c=-33

Factor and solve f(x) = x³ + 8x² - 23x - 30 given the fact that f(3) = 0
The factored form of f(x) = x³ + 8x² - 23x - 30 is (x - 3)(x + 10)(x + 1).
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
Given a polynomial f(x) = x³ + 8x² - 23x - 30.
If f(3) = 0 then x - 3 is one of the factors of the polynomial f(x).
∴ f(x) = f₁(x)(x - 3), where f₁(x) is a quadratic equation we obtain it by long division or synthetic division.
f₁(x) = x² + 11x + 10.
Now, x² + 11x + 10 = 0.
x² + 10x + x + 10 = 0.
x(x +10) + 1(x + 10) = 0.
(x + 10)(x + 1) = 0.
x + 10 = 0 Or x = 1 = 0.
x = - 10 Or x = - 1.

Step-by-step explanation:
the triangle has all equal angles
this means it is equilateral and this also means all the sides are equal
so take 2 sides and set them equal to each other to find x

The general form of the quadratic function is
y = [tex]ax^2[/tex] + bx + c
If a < 0, the quadratic function has maximum value
Here the value of a = -3
Therefore the function has maximum value.
Maximum value will be at x = -b / 2a
