Answer:

20

Step-by-step explanation:

According to Euclidian theorem:

h^2 = AD*CD (h is the height, DB in this case)

rewrite the equation by using given values

10^2 = 5*CD find the square value of 10

100 = 5*CD divide both sides by 5

20 = CD

Using the x-intercept concept, the function has x-intercept of 4 when c = -2.

The x-intercepts of a function are the values of x when y = 0.

In this problem, the function is:

cx - 5y + 8 = 0.

When y = 0, we have that:

cx + 8 = 0

x = 4, hence:

4c = -8

c = -2.

The equation that represents the given problem is (n-30) + n = 210. The correct option is the first option (n-30) + n = 210

From the question, we are to write an equation for the given problem

From the given information,

n = Tom's weight in pounds

If Jim weighs 30 pounds less than Tom

Then,

Jim weighs (n - 30)

Thus,

The sum of their weight is

(n-30) + n

∴ (n-30) + n = 210

Hence, the equation that represents the given problem is (n-30) + n = 210. The correct option is the first option (n-30) + n = 210

Answer:

  the numbers are 3, 5, 4

Step-by-step explanation:

The given relations can be written as a system of equations. These are conveniently solved using elimination.

Let the three numbers be represented by x, y, z. The given relations are ...

  x +y +z = 12

  x -y +z = 2

  x +y -z = 4

Subtracting the second equation from the first gives ...

  (x +y +z) -(x -y +z) = (12) -(2)

  2y = 10 . . . . . . . . . simplify

  y = 5 . . . . . . . . divide by 2

Subtracting the third equation from the first gives ...

  (x +y +z) -(x +y -z) = (12) -(4)

  2z = 8 . . . . . . . . . simplify

  z = 4 . . . . . . . . divide by 2

Using these values of y and z in the first equation lets us find x:

  x +5 +4 = 12

  x = 3 . . . . . . . . . subtract 9

The numbers, in order, are (3, 5, 4).

The measure of angle A is 144.3 degrees and the angle to cut the molding is 54.3 degrees

Start by solving the acute part of angle A using the following sine function

sin(Ax) = (30 - 4)/32

Evaluate the quotient

sin(Ax) = 0.8125

Take the arc sin of both sides

Ax = 54.3

The measure of angle A is then calculated as:

A = 90 + Ax

This gives

A = 90 + 54.3

Evaluate

A = 144.3

Hence, the measure of angle A is 144.3 degrees

In (a), we have:

Ax = 54.3

This represents the angle where the molding would be cut

Hence, the angle to cut the molding is 54.3 degrees

An interpretation of the relationship between the variables in this graph is that: C. you leave home, drive for 2 hours at a constant speed, and then stop for 1 hour. Finally, you continue at a slower (but constant) speed than before.

A graph can be defined as a type of chart which is used to graphically represent the relationship between the variables in a data set, on both the horizontal and vertical lines of a cartesian coordinate i.e x-axis and y-axis.

By critically observing the graph attached in the image below, we can infer and logically deduce that an interpretation of the relationship between the variables in this graph is that you drove at a constant speed for 2 hours, and then stopped for 1 hour.

The amount of paper that are needed to line the bottom of 3 drawers with paper is equal to 2,160 square inches.

First of all, we would calculate the area of the bottom of each drawer as follows:

Area = length × width

Area = 36 × 20

Area = 720 square inches.

Next, we would multiply this area by 3:

Total area = 720 × 3

Total area = 2,160 square inches.

Answer:

Step-by-step explanation:

To find the total perimeter of the parallelogram we must add 200+200+150+150

This equals 700. Then, since squares have side lengths that are all equal, we have to divide by 4.

700 / 4 = 175

So, the length of a side of a square having this perimeter would be 175mm

Let, f(x) = 0

0 = 10-5x

5x = 10

x = 2

f(2) = 10 - 10 = 0

f(5) = 10-5(5) = 10-25 = -15

Let, f(y) = f(x)

The 8% of us states have names that start with the letter w the answer is 8%.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The complete question is:

Of the 50 us states 4 have names that start with the letter w what percentage of us states have names that start with the letter w.

The percentage of the US states that have names that start with the letter W can be calculated:

Percentage = (No of US states starting with W/Total no of US states)×100

Percentage = (4/50)×100

Percentage = 8%

Answer:

Step-by-step explanation:

Total number of candies =60

Number of Green candies, n(G)=36

Number of candies with caramel, n(C)=45

Since the events are independent, the probability of selecting two candies where the first is green and the second has caramel is given by:

P(GC)=P(G) X P(C)

\begin{gathered}=\dfrac{n(G)}{n(S)} X \dfrac{n(C)}{n(S)} \\=\dfrac{36}{60} X \dfrac{45}{60}\\ =\dfrac{9}{20}\end{gathered}=n(S)n(G)Xn(S)n(C)=6036X6045=209

The probability in its lowest form is 9/20.

Using the quotient rule, the derivative of [tex]y[/tex] is

[tex]y' = \dfrac{(x^2-1) x' - x(x^2-1)'}{(x^2-1)^2} = \dfrac{(x^2-1) - x(2x)}{(x^2-1)^2} = -\dfrac{x^2+1}{(x^2-1)^2}[/tex]

as you're shown in the picture.

If [tex]y[/tex] has any local extrema, they occur at critical points where [tex]y'=0[/tex] or possibly when [tex]y'[/tex] is undefined.

In this case, [tex]y'[/tex] is undefined when [tex]x=1[/tex], but this is outside the domain of [tex]y[/tex] anyway, so we can ignore that.

That leaves us with the zero-case. For [tex]x\neq1[/tex], the denominator is always positive, so the numerator must be zero. But this never happens, since

[tex]-(x^2+1) = 0 \implies x^2 = -1[/tex]

but [tex]x^2\ge0[/tex] for all real [tex]x[/tex]. Therefore [tex]y[/tex] has no critical points and thus no extrema.
