Step 1: Define

Identify

3.14(a² + ab)

a = 3

b = 4

Step 2: Evaluate

Hey there!

3.14(a^2 + ab)

= 3.14(3^2 + 3 *4)

3^2

= 3 * 3

= 9

3 * 4

= 12

3.14(9 + 12)

9 + 12

= 21

3.14(21)

= 65.94

So, After simplify : [tex](2x+1)^3=8x^3+12x^2+6x+1[/tex]

Step-by-step explanation:

Given question :

[tex](2x+1)^3[/tex]

Now,

Applying this formula

[tex](a+b)^3=a^3+b^3+3ab(a+b)[/tex]

So,

[tex](2x+1)^3=(2x)^3+1^3+3(2x)(1)(2x+1)\\\\ (2x+1)^3 =8x^3+1+6x(2x+1)\\\\ ( 2x+1)^3 =8x^3+1+12x^2+6x\\ (2x+1)^3 =8x^3+12x^2+6x+1[/tex]

Answer:

The inequality that represents the graph is:

[tex]y\leq \frac{2}{3}x+2[/tex]

Step-by-step explanation:

First of all, we need to get the equation of the linear function. We need to choose two points using the graph.

The first point would be (-3,0)

The second point would be (6,1)

The equation of a line is:

[tex]y=mx+b[/tex]

m is the slope and can be calculated using the points chossen.

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

[tex]m=\frac{1+3}{6-0}[/tex]

[tex]m=\frac{4}{6}[/tex]

[tex]m=\frac{2}{3}[/tex]

Now, using one point we will find the b value. Let's chose (-3,0)

[tex]0=m(-3)+b[/tex]

[tex]0=(\frac{2}{3})(-3)+b[/tex]

[tex]0=-2+b[/tex]

[tex]b=2[/tex]

Then, the linear equation is:

[tex]y=\frac{2}{3}x+2[/tex]

Now, all the allowed values are below the function, therefore the inequality will be:

[tex]y\leq \frac{2}{3}x+2[/tex]

I hope it helps you!

Answer:

[tex]3\sqrt{10}[/tex]

Step-by-step explanation:

Given:

Area of a sector = 64 m²

The central angle is [tex]\theta=\dfrac{\pi}{6}[/tex].

To find:

The radius or the value of r.

Solution:

Area of a sector is:

[tex]A=\dfrac{1}{2}r^2\theta[/tex]

Where, r is the radius of the circle and [tex]\theta [/tex] is the central angle of the sector in radian.

Putting [tex]A=64,\theta=\dfrac{\pi}{6}[/tex], we get

[tex]64=\dfrac{1}{2}r^2\times \dfrac{\pi}{6}[/tex]

[tex]64=\dfrac{\pi}{12}r^2[/tex]

[tex]64\times \dfrac{12}{\pi}=r^2[/tex]

[tex]\dfrac{768}{\pi}=r^2[/tex]

Taking square root on both sides, we get

[tex]\sqrt{\dfrac{768}{\pi}}=r[/tex]

[tex]16\sqrt{\dfrac{3}{\pi}}=r[/tex]

Therefore, the value of r is [tex]16\sqrt{\dfrac{3}{\pi}}[/tex] m.

Answer:

12x+19

Step-by-step explanation:

First you would find the like terms. There is 9x and 3x, and 5, 2, 4, and 8. If you combine 9x and 3x, you get 12x, and if you combine 5, 2, 4, and 8, you get  19. You then combine your two answers to get 12x+19.

Answer:

12x + 19

Answer:

  a) t18,10 + t18,11

  b) t24,15 + t24,16

  c) t13,6 +t13,7

Step-by-step explanation:

Each term of Pascal's triangle is the sum of the two terms above it in the triangle:

  tn,r = t(n-1),(r-1) +t(n-1),r

__

a) t19, 11 = t18,10 + t18,11

b) t25,16 = t24,15 + t24,16

c) t14,7 = t13,6 +t13,7

Hi there!

I believe your answer is:

Here’s why:  

Assuming that the cake has one slice per person (16 slices):

⸻⸻⸻⸻

[tex]\frac{\text{price}}{\text{slice}}\\\\\rightarrow \frac{24}{16}\\\\\rightarrow \boxed{1.50}[/tex]

Answer: The equation of a line is y+6=-9(x-1). The slope of the line is -9 and the y-intercept is 3. A point on the line is (0, 3)

Step-by-step explanation:

Let's start by putting it in slope intercept form.

First use the distributive property

[tex]y+6=-9(x-1)\\y+6=(-9)(x)+(-9)(-1)\\y+6=-9x+9[/tex]

Now subtract 6 from both sides

[tex]y+6-6=-9x+9-6\\y=-9x+3[/tex]

Now it is in slope intercept form (y=mx+b)

In slope intercept form the slope of the line is the value m. In our equation the value m is -9 making that our slope.

In slope intercept form the y-intercept of the line is b. In our equation the value of b is 3 making that our y-intercept.

To find a point on the line we can sub x with any number to find the y so that we can find the coordinate.

[tex]y=-9(0)+3\\y=0+3\\y=3[/tex]

A point on the line is (0, 3)

Answer:   a = -4,  b = 8,  c = 3

This is because the general template is ax^2+bx+c

Matching up the terms gets us what is shown in bold. The x's are not involved as part of a,b,c. We just focus on the numbers in front.

The graph is shown below. I used GeoGebra to make the graph.

Yes, the triangles are congruent according to the figure.

Two triangles are said to be congruent if pairs of their corresponding sides and their corresponding angles are equal.

Given that are two triangles, we need to check whether they congruent or not,

So, we are given,

BC = EF

AC = DF

∠ A = ∠ D = 90°

Therefore.

Δ ABC ≅ Δ DEF by SSA rule

since, the triangles are congruent by SSA rule,  

Hence, the given statement is true.

Answer:

Step-by-step explanation:

Given :

Number of people who spoke French as first language in 2000 = 7.7 * 10^7 ; in standard form ;

7.7 * 10^7 = 7.7 * (10 * 10* 10 * 10* 10* 10 * 10) = 77,000,000 = 77 million

Number of people who spoke German as first language in 2000 = 1 * 10^8 ; in standard form ;

1 * 10^8 = 1 * (10 * 10* 10 * 10* 10* 10 * 10 * 10) = 100,000,000 = 100 million

Answer: The given statement is true.

Step-by-step explanation:

Significant figures are defined as the figures that are present in a number. It expresses the magnitude of a quantity to a specific degree of accuracy.

There are some rules to detect the significant figures in a number:

Rule applied when numbers are added or subtracted:

The number having less number of significant figures after the decimal point will determine the number of significant figures in the final answer.
