The values that make the inequality -2h ≤ -40 true are

Equivalent form of the inequality is written as

Inequality is a means of representing the relationship existing between the positive and negative parts of equations, using other terms aside exactly using only "equal to"

solving the inequality

-2h ≤ -40

dividing through by a negative number changes the inequality

diving through by -2 gives

h ≥ 20

Therefore, h are values greater than 20 and 23, 25, and 30 are all greater than or equal to 20

The graph of the given absolute function is attached below and the end points (-5,0) (0, 5) of the rays are marked in it.

Absolute value function:

The  function that contains an algebraic expression within absolute value symbols is called as absolute value function.

Given,

Here we have the absolute value function f(x) = |-x - 5|

Now, we have to plot the graph for this function and we have to mark the end point of the rays.

Here the given function is written as,

=> f(x) = | -x - 5|

In order to plot the graph for the function we need the table of values to point it on the graph,

For that we have to take following sample values,

When x = -5, then f(-5) = |-5 -5| = 0

When x = 0,  then f(0) = |0 - 5| = 5

Therefore, the end points of the rays are (-5,0) and (0,5)

Now, we have to plot these values on the graph.

Then we get the graph like the following.

Answer:

Step-by-step explanation:

Number of Latvian footballers(n¹) = 36

Numer of footballers of other nationalities(n²)=36/4=9

Now total number of footballers= n¹+n²= 36+9 =45

If he borrowed $1400 at 9% simple interest to be paid back in 2 years. The  interest he will pay is $1,663.34.

Using this formula

Interest = Principal ( 1+ Interest rate)^ time

Where:

Interest =?

Principal = $1400

Interest rate = 9% or 0.09

Time = 2 years

Let plug in the formula

Interest = $1,400 ( 1+ 0.09) ^ 2

Interest = $1,400 ( 1.09) ^2

Interest = $1,400 ( 1.1881)

Interest = $1,663.34

Question 1:

The angle m∠DOX is greater than 90 degrees, but less than 135 degrees.

Looking at the diagram we see that:

m∠DOX = 120 degrees.

Question 2:

The angle m∠COX is the sum of two angles that in total are 80 degrees.

Therefore, the equation is:

m∠COX = m∠AOX + m∠COA

Question 3:

The BOA angle measurement is given by:

BOA = 60 - 40

BOA = 20 degrees

Therefore, an angle that measures 20 degrees is:

BOA.

Question 4:

From the previous question we have:

m∠BOA = 60 - 40

m∠BOA = 20

Step-by-step explanation:

The unknown side and angle of the triangle is as follows:

A right angle triangle is a triangle that has one of its angles as 90 degrees. The side of a right angle triangle can be found using trigonometric ratios.

Hence, let's find x, y and z.

The sum of angles in a triangle is 180 degrees.

Hence,

180 - 27 - 90 = x

x = 63 degrees.

sin 63° = opposite / hypotenuse

sin 63 = y / 35

cross multiply

y = 35 sin 63

y = 31.1852283466

y = 31.19 units

sin 27 = z / 35

z = 35 sin 27

z = 15.8896674909

z = 15.89 units

The perimeter of the triangle ABC with respect to the given information is 78.

Whether it be a two-dimensional shape or a one-dimensional length, a perimeter is a closed path that contains, surrounds, or delineates it. A circle's or an ellipse's circumference is its furthest boundary. Numerous real-world uses exist for calculating perimeter. Adding the lengths of all the sides and edges that surround a shape yields its perimeter. It is calculated using linear length units like centimeters, meters, inches, and feet.

Given,

In triangle QRS,

A is the midpoint of QR, B is the midpoint of RS, and C is the midpoint of SQ.

And also given that QA=10, BR=15, SQ=28

Let p represent the triangle ABC's perimeter.

Step-by-step explanation:

After flipping a fair coin, when 'H' represents the heads and 'T' represents the tails the probability of heads P(H) = 1/2 and probability of tails P(T) = 1/2.

As given in the question,

After flipping a fair coin, when 'H' represents the heads and 'T' represents the tails ,

Number of total outcomes = { H , T }

Total number of outcomes = 2

Number of favourable outcomes to represent heads = 1

Number of favourable outcomes to represent tails = 1

Probability =(Number of favourable outcomes)/ (Total number of outcomes)

Probability of getting heads from the total outcomes is equal to

P(H) = 1 / 2

Probability of getting tails from the total outcomes is equal to

P(T) = 1/2

Difference quotient for f(x) = √x at (16,4) is  √16+h - 4 / h

Difference quotient is mathematical operation used to solve derivation of function by using following formula :

difference quotient = [tex]\frac{f(x+ h) - f(x) }{h}[/tex]

For the function f(x) =  √x at point (16,4)

f(x +h) = [tex]\sqrt{x+h}[/tex]  

putting value in formula

difference quotient =  [tex]\frac{\sqrt{x+h} -\sqrt{x} }{h}[/tex]

now , putting x = 16 ,

difference quotient = √16+h - √16 / h

taking square root of 16 ,
