The solution to the inequality n - 4/7 ≥ -2/3 is (a) n ≥ -2/21

From the question, we have the following parameters that can be used in our computation:

n minus four sevenths is greater than or equal to negative two thirds

By definition, inequalities are used to relate unequal values

Express the inequality properly

So, we have

n - 4/7 ≥ -2/3

Add 4/7 to both sides

So, we have

n ≥ -2/3 + 4/7

Evaluate the sum of the fractions

This gives

n ≥ -2/21

Hence, the solution is (a) n ≥ -2/21

The time taken for the population to reach 26.6 million is 2 years while the population in year 2000 is 18.5 million.

We can be able to  define population growth as the process by which the population of an area is increasing. We know that the increase or the decrease of population would have to be an exponential function.

Given that we have the function A =18.5e^0.1708t where A is the population after a given time from year 2000 and t is the number of years after year 2000. It then follows that 18.5 million refers to the population of the united states as at year 2000.

We now have;

26.6 =18.5e^0.1708t

26.6/18.5 = e^0.1708t

1.44 = e^0.1708t

ln(1.44) = 0.1708t

t = ln(1.44)/ 0.1708

The value(s) of a where the tangent line to the graph of the function f(x) = -11x + is parallel to the line y = -19x - 18 is x=1,-1.

What is Slope of function?

Finding the rate at which the value of y (the dependent variable) changes in relation to x is what this method entails (independent variable). The slope itself identifies the line's slope and direction. Write the equation of the line in slope-intercept form to determine the slope from the equation. Utilize inverse procedures to find y, then write it as y=mx+b. Since the slope is the x variable's coefficient, or the number before x, you can thus readily observe the slope.

[tex]f(x)=-11 x+\frac{8}{x}$$[/tex]

Slope of function [tex]$\rightarrow f^{\prime}(x)=\frac{-21-8}{x^2}$[/tex]

Given line: y=-19 x-18

Slope [tex]$\rightarrow y^{\prime} \rightarrow-19$[/tex]

Since function and line both are parallel, hence slope of both will be equal.

             ________________

5x ²-5x | 20x³ - 15x² -15x+16

1            -(20x³ - 20x²)                      ==> -15x²-(-20x²)= -15x²+20x² = 5x²

                         5x² - 15x

An exponentially decaying function has a general form f(x) = (1 -r)ˣ, where r is called the decay rate. it can be found by having any two values of x for which f(x) is known.

The given function for the decay of an isotope is given as A(t) = 200[tex]e^-0.054t[/tex].

Now, the given problem can be solved as follows,

(a) The amount of sample after 25 years is given as,

A(25) = 200[tex]e^{-0.054 \times 25}[/tex]

         = 200[tex]e^{-1.35}[/tex]

A straight line of numbers is shown visually as a number line. This line is used to compare integers on an endless line that extends on both sides, either horizontally or vertically, at equal intervals. On a horizontal number line, the numbers grow as we walk to the right and decrease as we move to the left.

It is given that Evan added -2 1/2 and 4 but got 6 1/2

The mistake that Evan did was instead of adding, he substracted -2 1/2 from 4, and thus he got 6 1/2. This is because

Step-by-step explanation:

that is a college question ?

oh my ...

to clarify :

perpendicular means intersecting or touching at a right angle (90°).

bisector means it is a line that cuts the other line in half.

1.

because of the bisector this means DF = FC = DC/2.

so, since FC = 17, so is DF (=y) = 17.

2.

for the same reason

2x - 3 = x + 8

x - 3 = 8

x = 11

the angle must be 90°.

so,

5y = 90

y = 18

3.

for the same reason

10 = 4a

a = 10/4 = 2.5

4.

for the given reasons of 1-3, this figure is a kite. that means the left side is a mirror image of the right side. so, all the lengths on one side are equation to the lengths of the other side.

x - 11 = 19

x = 30

5.

for the same reasons

3y + 5 = 26

3y = 21

y = 7

6.

the perimeter of EDP is then

EP + DP + ED = 19 + 19 + (9 + 9) = 56

because ED = EC + CD

and for the above reasons EC = CD = 9

so, ED = 9 + 9 = 18

7.

the perimeter of EDQ is then

EQ + DQ + ED = 26 + 26 + 18 = 70

8.

for the same reasons as above

x = 90°

9.

remember, the sum of all angles in a triangle is always 180°.

180 = 90 + 55 + y

y = 180 - 90 - 55 = 35°

10.

180 = y + M + z = 35 + (55+71) + z = 161 + z

z = 180 - 161 = 19°

Answer:

Yes

Step-by-step explanation:

The size of each angle of triangle, starting with the largest 90°, 45° and 45°.

Polygon which has three sides and three vertices is called as triangle.

Sum of all the angles of the triangle is 180°.

Given that a right angled triangle has two equal sides.

And the largest triangle of right angled triangle is 90°.

Right angled triangle which has two equal sides can be called right angled isosceles triangle.

And if one angle of isosceles triangle have angle is 90°. Then the rest of the two angle will be 45°.

Therefore, The rest of these two angles of the right angled triangle are 45⁰.

The side lengths of the triangle are 11.1, 21.4, and 18.5 units.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

The given sides of the right triangle are 3m, 2m+14, and 5m.

As per the Pythagorean theorem, it follows:

(2m + 14)² = (3m)² + (5m)²

4m² + 196 + 56m = 9m² + 25m²

30m² -56m - 196 = 0

15m² - 28m - 98 = 0

[tex]m=\frac{-(-28)\pm\sqrt{(-28)^2-4(15)(-98)}}{2(15)}\\\\m=\frac{28\pm\sqrt{6664}}{2(15)}\\\\m =\frac{28\pm81.6}{2(15)}\\\\m=3.7\text{ or } m=-1.8[/tex]

Since the lengths cannot be negative, the value of m is m = 3.7.

Therefore, the side lengths of the triangle are:

3m = 3(3.7)

= 11.1

2m + 14

= 2(3.7) + 14

= 21.4

it is given that ,

the parametric equation is x = t⁴ + 3 , y = t³ + t ,

differentiating with respect to t ,
