Answer:

Slope = 27/11

AB = 29.15 u

Step-by-step explanation:

Given :-

To Find :-

We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,

[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]

[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]

Hence the slope of the line is 27/11 .

[tex]\rule{200}2[/tex]

Finding the length of AB :-

[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]

Hence the length of AB is 29.15 units .

Answer:

x = 2

Step-by-step explanation:

According to the inscribed Angle Theorem, the size of an inscribed angle = ½(measure of the intercepted arc)

m<L = (7x + 9)° is an inscribed angle

m(KM) = 46° is its intercepted arc

Therefore:

7x + 9 = ½(46)

Multiply both sides by 2

2(7x + 9) = 46

14x + 18 = 46

14x + 18 - 18 = 46 - 18

14x = 28

14x/14 = 28/14

x = 2

Answer:

Which expression is equivalent to (6x3+3x2+8)+(2x2−9x+10)?

Step-by-step explanation:  

6x3+3x2+8)+(2x2−9x+10)?

The equivalent expression is 6x^3+5x^2-9x+18.

An expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Algebraic expressions include at least one variable and at least one operation.

For the given situation,

The expression is [tex](6x^3+3x^2+8)+(2x^2-9x+10)[/tex]

⇒ [tex]6x^{3}+3x^{2} +8 +2x^{2} -9x+10[/tex]

Rearrange the expression in decreasing order of polynomial,

⇒ [tex]6x^{3}+3x^{2}+2x^{2} -9x+8+10[/tex]

Now add the like terms,

⇒ [tex]6x^{3} +5x^{2} -9x+18[/tex]

Hence we can conclude that the equivalent expression is [tex]6x^{3} +5x^{2} -9x+18[/tex].

Tyler visited five friends at their respective houses. The area of the route he covered is 16 square blocks.

For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.

Then it means

[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.

[tex] \frac{1}{3} {a}^{2} h = 20 \\ {a }^{2} = 20 \div 5 \\ {a}^{2} = 4 \\ a = 2[/tex]

Answer:

14400km/h

Step-by-step explanation:

Given that

The speed of the car increased from 40 km/hr to 60 km/hr

And, the time taken is 5 seconds

we need to find out the acceleration of the car

So,

Here

u =  initial velocity =40km/h

v = final velocity =60km/h

t = time = 5s =5 ÷ 3600h

a = acceleration

Now as we know that

a = (v - u) ÷ t

= (60 - 40) ÷ (5 ÷ 3600)

= (20 × 3600) ÷ 5

= 14400km/h

Answer:

B

Step-by-step explanation:

First, we can determine the zeros of the function.

We can see that the graph passes through the x-axis at the points: x = -4, -2, and 1.

Therefore, we have three factors:

[tex](x-(-4)),\, (x-(-2))\text{ and } (x-(1))[/tex]

Thus, our function will be:

[tex]y=(x+4)(x+2)(x-1)[/tex]

Our answer is B.
