The value of the exponent 3.6 x 10^7 + 2.1 x 10.^7 is D. None of the above.

The exponent is the number of times that a number is multiplied by itself. It should be noted that the power is an expression which shows the multiplication for the same number. For example, in 6⁴ , 4 is the exponent and 6⁴ is called 6 raise to the power of 4.

In this case, the value of 3.6 x 10^7 + 2.1 x 10^7 will be:

= 3.6 x 10^7 + 2.1 x 10.^7

= 5.7 × 10^7

Therefore, the correct option is D.

If a - b = -5 and ab = 0 then the value of the expression a³-b³ is -125.

In the question ,

it is given that ,

the value of a - b = -5 and ab = 0

we need to find the value of the expression (a³-b³) ,

we know the identity that a³-b³ = (a - b)(a² + b² + ab)

we first need the value of a² + b² .

given that a - b = -5

squaring both the sides , we get

(a - b)² = 25

a² + b² - 2ab = 25

given ab = 0, so a² + b² = 25

Substituting a² + b² = 25 in the identity a³-b³ = (a - b)(a² + b² + ab) ,

we get ,

a³-b³ = (-5)(25 + 0)

a³-b³ = -5 × 25

a³-b³ = -125

the answer is -125 .

Therefore , If a - b = -5 and ab=0 then the value of the expression a³-b³ is -125.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

For a given right triangle, the expression is,

⇒ sin (3x - 7) = cos (x + 1)

Now,

Solve for x as;

The expression is,

⇒ sin (3x - 7) = cos (x + 1)

Since, sin x= cos (90 - x)

So, We get;

⇒ sin (3x - 7) = cos (x + 1)

⇒ cos (90 - (3x - 7)) = cos (x + 1)

⇒ 90 - (3x - 7) =  (x + 1)

⇒ 90 - 3x + 7 = x + 1

⇒ 97 - 3x = x + 1

⇒ 97 - 1 = x + 3x

⇒ 96 = 4x

⇒ 4x = 96

⇒ x = 96/4

⇒ x = 24

Answer:

$134.86

Step-by-step explanation:

Let the original price before tax be x.

A whole amount is 100% of the amount, so x is 100% of the original price without tax.

The tax rate is 6%, so the tax on x is 6% of x. Add 6% of x to 100% of x, and you have 106% of x. The item plus tax cost 106% of x.

106% of x = $142.95

106/100 × x = 142.95

1.06x = 142.95

x = 142.95/1.06

Step-by-step explanation:

The domain of the function A(m) = 184 - 8m representing the bank charges on monthly fees is m ≤ 23

The equation is linear equation in the slope intercept form as

y = mx + c

where

m = slope = -8

c = intercept = 184

x = input variables = m

y = output variables = A(m)

The domain refers to all possible values of m, generally the equation has no restriction for m however for the problem being discussed y should not be negative. hence we solve for m when y = 0

0 = 184 - 8m

8m = 184

m = 23

The maximum value of m is 23 hence the domain is m ≤ 23

Answer:

second number = (x + 7.5)

Since the product of the two numbers is double of their sum,

             x(x + 7.5) = 2(x + x + 7.5)

             x² + 7.5x = 2(2x + 7.5)

             x² + 7.5x = 4x + 15

x² + 7.5x - 4x - 15 = 0

      x² + 3.5x - 15 = 0

                      ∴ x = -6 or 2.5

∴ second number

= -6 + 7.5 or 2.5 + 7.5

= 1.5 or 10

∴ The two numbers that I am thinking of are either -6 and 1.5 or 2.5 and 10.

The line equation passing through the given points and parallel to the given lines are:

Line 1: y=-4x+13...(i)

Line 2: y=2x-12...(ii)

Line 1

The first line is passing through point (1,9) and parallel to the y=4x+2 line.

Since line 1 would be parallel to line y=4x+2, hence both lines would have the same value of slope (m).

Using the standard formula of line equation, we could identify that line y=4x+2 has:

ay = bx + c, m= -b/a

y=4x+2, m=-4

We could use the line equation formula, where:

y-y1 = m (x-x1)

we use the given point (1,9) and the slope value (m=-4) to get the line equation passing through the point:

y-9 = -4(x-1)

y-9=-4x+4

y=-4x+13...(i)

Line 2

The first line is passing through point (5,2) and parallel to the y=-2x+7 line.

Since line 2 would be parallel to line y=-2x+7, hence both lines would have the same value of slope (m).

Using the standard formula of line equation, we could identify that line y=-2x+7 has:

ay = bx + c, m= -b/a

y=-2x+7, m=-2

We could use the line equation formula, where:

y-y2 = m (x-x2)

we use the given point (5,2) and the slope value (m=2) to get the line equation passing through the point:

does 150 split up into 5 even parts??

hmmm  you probably are thinking,  15 does divide by 5 evenly into 3 parts, so we now know that 150 also splits up into 5 even parts of 30  :)

2 time 30 = 60

so there is how to figure out the answer and , the answer 60 :)

Answer:

The slope (constant rate of change) is 5.

A situation which could be represented by this graph is: A student walks 1.5 km to a friend’s house in 20 minutes. The two students then walk another 1.5 km to school in 40 minutes.

In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate respectively such as time (min) and distance (km).

In this scenario, the time (in minutes) was plotted on the x-axis of the graph while the distance covered (in kilometers) was plotted on the y-axis of the graph.

By critically observing the graph (see attachment), we can reasonably and logically deduce that the first student walked a distance of 1.5 kilometer to his or her friend’s house in 20 minutes, then, they both walked at a constant speed for 5 seconds before increasing their speed, covering another distance of 1.5 kilometer to their school within 40 minutes (60 - 20 minutes).

a = -6 /10 = - 3/5

y = -3/5 (x+2)(x-5)  

Answer:

[tex]\textsf{Intercept form}: \quad y=-\dfrac{3}{5}(x+2)(x-5)[/tex]

[tex]\textsf{Standard form}: \quad y=-\dfrac{3}{5}x^2+\dfrac{9}{5}x+6[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6 cm}\underline{Intercept form of a quadratic equation}\\\\$y=a(x-p)(x-q)$\\\\where:\\ \phantom{ww}$\bullet$ $p$ and $q$ are the $x$-intercepts. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]

If the x-intercepts are (-2, 0) and (5, 0) then:

Substitute the values of p and q into the formula:

[tex]\implies y=a(x-(-2))(x-5)[/tex]

[tex]\implies y=a(x+2)(x-5)[/tex]

To find a, substitute the given point on the curve P (3, 6) into the equation:

[tex]\implies 6=a(3+2)(3-5)[/tex]

[tex]\implies 6=a(5)(-2)[/tex]

[tex]\implies 6=-10a[/tex]

[tex]\implies a=\dfrac{6}{-10}[/tex]

[tex]\implies a=-\dfrac{3}{5}[/tex]

Substitute the found value of a into the equation:

[tex]\implies y=-\dfrac{3}{5}(x+2)(x-5)[/tex]

Expand to write the equation in standard form:

[tex]\implies y=-\dfrac{3}{5}(x^2-3x-10)[/tex]

The quadratic equation whose sum of two real roots is 31 and product is 210 will be [tex]x^{2} -31x+210 = 0[/tex].

According to the question,

We have the following information:

The sum of roots of a quadratic equation = 31

The product of roots of a quadratic equation = 210

We know that the standard form of the quadratic equation is given as follows:

[tex]ax^{2} +bx+c = 0[/tex]

Now, the sum of roots is -b/a and the product of roots is c/a.

So, we have the following expressions:

-b/a = 31

b = -31 and a = 1

c/a = 210

c = 210 and a = 1

So, the equation will be:

[tex]x^{2} -31x+210 = 0[/tex]

Hence, the quadratic equation whose sum of two real roots is 31 and product is 210 will be [tex]x^{2} -31x+210 = 0[/tex].

The two coordinates on the segment AB due to internal division are (5,0) and (-3,-4).

What is internal division?

When a point P divides the line joining the two points and the potint P lies in between the two coordinates then the division is internal division. If the point lies outside of the given coordinates then the division is known as external division.

The division is internally because point P lies on the line as given in the question.

The formula for the internal division is as follows:

[tex]X=\frac{mx_1+nx_2}{m+n}\\Y=\frac{my_1+ny_2}{m+n}[/tex]

Since points are A(-5,-5) and B(7,1) hence, [tex]x_1=-5,x_2=7,y_1=-5,y_2=1[/tex] and ratio is 1:5 then [tex]m=1,n=5[/tex].

Substute all value to obtain the coordinates.

[tex]X_1=\frac{1(-5)+5(7)}{1+5}\\X_1=5\\Y_1=\frac{1(-5)+5(1)}{1+5}\\Y_1=0[/tex]

Hence, the first cordinate is (5,0).

As given in the question that the ratio in not necessarily in the order of 1:5 so, consider the ratio is 5:1.

Now, m=5 and n=1.

Again substitute all values in to find the new coordinate.

[tex]X_2=\frac{5(-5)+1(7)}{5+1}\\X_2=-3\\Y_2=\frac{5(-5)+1(1)}{5+1}\\Y_2=-4[/tex]

Hence, another coordinate is (-3,-4).
