Answer:

The solutions are x=0, x=1

Step-by-step explanation:

we know that

The solution of the equation f(x)=g(x)

are the values of x when the value of f(x) is equal to the value of g(x)

Observing the table

For x=0

f(0)=1  and g(0)=1

so

For x=0 ------> f(x)=g(x)

For x=1

f(1)=1/2  and g(1)=1/2

so

For x=1 ------> f(x)=g(x)

therefore

The solutions are x=0, x=1

Answer:

[tex]20x^{11}[/tex]

Step-by-step explanation:

An expression in algebra that contains one term is called a monomial.

These include numbers, whole numbers and variables that are multiplied together.

Any number, a whole number without variables can also be monomial, like 32, 5236 etc.

So, here the monomial is [tex]20x^{11}[/tex].

Option (A) represents a monomial which has only one term option (A) 20x¹¹ is correct.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

As we know in the monomial there will be only one term.

Option (C) and Option (D) contains two terms so they are not monomial.

Option (B) contain fractional term.

Thus, option (A) represents a monomial which has only one term option (A) 20x¹¹ is correct.

Answer:

  x = 1

Step-by-step explanation:

The graph is shown below. The solution is x = 1.

___

√x +2 = 3x . . . . given

√x = 3x -2 . . . . . subtract 2

x = 9x^2 -12x +4 . . . . square both sides

9x^2 -13x +4 = 0 . . . . subtract x to put in standard form

(x -1)(9x -4) = 0 . . . . . factor the quadratic

x = 1 . . . or . . . x = 4/9 . . . . values of x that make the factors zero

The "solution" x = 4/9 is extraneous, in that it does not satisfy the equation. It would correspond to the intersection of the line with the negative branch of the square root function. That is, it does satisfy -√x +2 = 3x.

The solution is x=1.

Step-by-step explanation:

√(a³b⁴)

Root both variables. Note that pairs of the same variables can be brought out of the root.

√(a³) = √(a * a * a) = a√a

√(b⁴) = √(b * b * b * b) = b²

(a)(b²)√a is your answer.

Answer:

7 billion

Step-by-step explanation:

Rounding decreqases when number is under 5 and if its above (Ex, 7,685,000,000) it is rounded to 8 billion. But here, it is under 5 so it is 7 billion.

Answer:

7,000,000,000

Step-by-step explanation:

Note the Billions place value. 7 is in the billions place value. To find out if you round up or down, look at the place value directly to the right of the one you are trying to find, in this case, being the hundred million place value. The value inside the hundred million place value is a 1.

Note that the number has to be 5 or greater to round up, or else you round down. Because 1 < 5, you round down.

7,125,000,000 rounded to the nearest billion is 7,000,000,000.

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Slope = change in y ÷ change in x

The line passes through (3,7) and (-1,4)

Slope = [tex]\frac{7 - 4}{3 - -1}[/tex] = [tex]\frac{3}{4}[/tex]

For this case we have that by definition, the slope of a line is given by:

[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}[/tex]

According to the data we have the following points:

[tex](x_ {1}, y_ {1}): (- 1,4)\\(x_ {2}, y_ {2}) :( 3,7)[/tex]

Substituting we have:

[tex]m = \frac {7-4} {3 - (- 1)} = \frac {3} {3 + 1} = \frac {3} {4}[/tex]

Thus, the slope of the line is [tex]\frac {3} {4}[/tex]

Answer:

[tex]\frac {3} {4}[/tex]

Answer:

The answer is B.

e^a=55

Taking log on both sides,

lne^a = ln 55

a lne= ln55

a= ln55.

The value of the expression [tex]e^a = 55[/tex] in the logarithmic equation is equivalent to (ln 55=a).

A log function is a way to find how much a number must be raised in order to get the desired number.

[tex]a^c =b[/tex]

can be written as

[tex]\rm{log_ab=c[/tex]

where a is the base to which the power is to be raised,

b is the desired number that we want when power is to be raised,

c is the power that must be raised to a to get b.

We solve the value of this expression using the basic logarithm,

[tex]\rm{log_ab=c[/tex]

Similarly,

[tex]\rm{log_e55=a[/tex]

we know that the log base of exponent is natural log, therefore,

[tex]\rm ln\ 55=a[/tex]

Therefore, the value of the expression [tex]e^a = 55[/tex] in the logarithmic equation is equivalent to (ln 55=a).

m = males = 50

e = females = 25

a = adults = 7

Step-by-step explanation:

Givens

Let the adults = a

let the males students = m

lef the female students = e

Equations

a + m + e = 82                                  

m = 7*a + 1

e = 1/2 * (7a + 1)

Solution

a + 7a + 1 + 1/2(7a + 1) = 82                 Remove the brackets on the left.

a + 7a + 1 + 3.5*a + 1/2 = 82                Combine the like terms on the left.

11.5a + 1.5 = 82                                    Subtract 1.5 from both sides.

11.5a + 1.5 - 1.5 = 82 - 1.5                     Combine

11.5a = 80.5                                          Divide by 11.5

a = 80.5/11.5

a = 7                  

The number of adults = 7

===============================

m = 7a + 1

m = 7*7 + 1

m = 50

If you look at the graph, the line crosses the y axis at (0,3).

That means you can eliminate the inequality that shows the y intercept as -3 (which is the 3rd option)

Also the inequality has to have y ≤ ....     so that the correct part of the graph is shaded. This elimates all of the inequalities that has y ≥ ... ( which is the 2nd and 4th option)

This leaves you with only the first inequality left:

Answer:

X

The given statement is true.

Step-by-step explanation:

An inverse function can be defined as  a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.

Examples are x+2 and x-2

WE get f(x) = x+2

Apply g(x) = g(f(x))=g(x+2)

=x+2-2=x

Thus by applying composiiton g f or fg in any order we get the answer as x

[tex]77500[/tex]

In this case, the digit in the hundredths place is a [tex]5[/tex].  We need to take a look at the next digit to the right, which is a [tex]4[/tex].

Since it is [tex]4[/tex] or less, we can simply replace the [tex]4[/tex] and the rest of the digits to the right with [tex]0[/tex]s to round it.

If the [tex]4[/tex] was [tex]5[/tex] or more, we would round the [tex]5[/tex] up to [tex]6[/tex] and replace the remaining digits to the right with [tex]0[/tex]s.

Answer:

77500

Step-by-step explanation:

To round something to the nearest hundred, we first look to the 10s digit. It is 4. Since 4 is less than 5, then we keep the same hundreds place. So we get 77500.

Answer:

x = 8

Step-by-step explanation:

Step 1: Write an equation

2x - 9 = 7

Step 2: Use the Addition Property of Equality

2x = 16

Step 3: Use the Division Property of Equality

x = 8

Answer:

number = 8

Step-by-step explanation:

Let "number" = x. Set the equation.

"product of 2 and number" = 2(x)

"nine less" = -9

"equal to 7" = "= 7"

2x - 9 = 7

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 9 to both sides.

2x - 9 (+9) = 7 (+9)

2x = 7 (+9)

2x = 16

Divide 2 from both sides.

(2x)/2 = (16)/2

x = 16/2

x = 8

8 is your answer.

Answer:

29.74 degrees.

Step-by-step explanation:

Tan(theta) = opposite / adjcent.

opposite = 8

adjacent = 14

Tan(theta) = 8/14

Tan(theta) = 0.5714

theta = tan^-1(0.5714)

theta = 29.74 degrees

By using the concept of slope of a Straight line,we arrive to the conclusion that the equation of line through (2,-4) and having slope off 3/5 is  y = - (1/2)x - 26/5.

The slope of this Straight line is given as=3/5

Thus,the equation of the straight line becomes y=(3/5)x [tex]+[/tex]c.

Now,if substituting the Slope of the line in the equation of this line.

y=(3/5)x [tex]+[/tex]c.

In the point(2,-4):

-4=(3/5)(2) [tex]+[/tex] c

-4=(6/5) [tex]+[/tex] c

c=-4-(6/5)

  = - 26/5

Therefore, the final equation is y= - (1/2)x - 26/5

Answer:

√61

Step-by-step explanation:

Distance between 2 points (x1, y1) and (x2,y2) is given by

Distance = √ [ (x2-x1)² + (y2-y1)² ]

in our case, x1 = 0, y1 = 6, x2 = 5, y2 = 12

Distance

= √ [ (5-0)² + (12-6)² ]

= √ [ (5)² + (6)² ]

= √ 61

Answer:

√61

Step-by-step explanation:

The distance between two points is given by

d = sqrt( (x2-x1)^2 + (y2-y1)^2)

  = sqrt( (5-0)^2 + (12-6)^2)

  =sqrt( 5^2 + 6^2)

Answer:

= 135 m²

Step-by-step explanation:

First we divide the kite into 2  isosceles triangles

The bigger triangle has base angles = 45°

We can use these angle as follows to find the common base of the two triangles.

Cos 45=adjacent/9√2

Adj=9√2×cos 45

=9

common base =9×2=18

We can use the angle 45° above to find the height of the bigger triangle.

Tan 45°=opposite/adjacent

Opposite = adjacent×Tan 45

=9 tan 45=9

Area =1/2BH+1/2Bh where B is the common base H is the height of the big triangle, h represents the height of the smaller triangle.

A=1//2× 18 × 9 +1/2× 18 × 6

i.e.

we are asked to find the product of a quadratic and a linear polynomial.

We are asked to find the result of:

[tex](-8y^2+3)\cdot (-4y-3)[/tex]

Hence, on using the distributive property we have:

[tex]-8y^2(-4y-3)+3(-4y-3)\\\\=-8y^2\times -4y-8y^2\times (-3)+3\times (-4y)+3\times (-3)\\\\i.e.\\\\=32y^3+24y^2-12y-9[/tex]
