The answer is D

Step-by-step explanation:

Alonzo used 5.3 in his model instead of .53

Answer:

Step-by-step explanation:

cos(2θ) - cosθ + 1 = 0

2cos²θ - 1 - cosθ + 1 = 0

2cos²θ - cosθ = 0

2cosθ(cosθ - 1/2) = 0

cosθ = 0, θ = π/2, 3π/2

cosθ = 1/2, θ = π/3. 5π/3

So answer is 3rd choice

Answer:

[A] y(y + 4) - y = 6

[C] 4 b (b)=0

Step-by-step explanation:

First let know what is a quadratic functions(s):

A function is called Quadratic if it consist of  only one variable, maximum of three terms, and highest degree of the variable  in that Polynomial is 2.

Now let's go through the answer choices:

[A]  

y *(y+4) - y =6

y² + 4 y - y -6=0

y²+3 y -6=0

Thus, This is Quadratic Function.

[B]

3 x +2 + 6 x -1=0

9 x-1=0

Thus, This is not Quadratic Function

[C]

4 b*(b)=0

4 b²=0

Thus, This is Quadratic Function.

[D]

3 a- 7 =2 * (7 a-3)

3 a - 7=14 a - 6

3 a - 14 a = 7 -6

-11 a =1

Thus, This is not a Quadratic Function.

Hence, [A] and [C] are quadratic functions.

Answer:

D.  Makes both the top and bottom inequalities true

Step-by-step explanation:

System of linear inequalities

Consider these two inequalities:

2x+3y > 20

3x-2y > 5

The solution of the system consists of all the ordered pairs (x,y) that satisfy both inequalities. The ordered pair (3,5) makes the first inequality true because

2*3+3*5=21 and it's effectively greater than 20.

But that pair makes the second inequality false, since

3*3-2*5=-1 is not greater than 5.

Thus, the pair (3,5) is not part of the solution.

If we test the pair (6,2), we'll check both inequalities are true, thus (6,2) is part of the solution.

Thus, the correct answer to the question is

D.  Makes both the top and bottom inequalities true

Answer:

Answer:

80

Step-by-step explanation:

The sum of the measures of the interior angles of a triangle is 180 degrees, so:

x+(x-15)+(x-45)=180

x+x-15+x-45=180

3x-60=180

3x=240

x=80

Step-by-step explanation:

Here,

[tex]\angle{ADB}[/tex] = [tex]\angle{BDC}[/tex]

⇒4x-23° = 3x-5°

⇒4x-3x=(-5°)+23°

⇒x=18°

.°. x = 18°

Answer:

x = 18°

12.3455882353

Step-by-step explanation:

(103/8) = 12.875

(9/14) = 0.64285714285

0.64285714285 x 14 = 9

(9/17) = 0.5294117647

12.875 - 0.5294117647 = 12.3455882353

equivalent expression

y (6+7) = 13y

Answer:6y+7y or 13y

Step-by-step explanation:

y multiply 6 is 6y

y multiply 7 is 7y

Therefore it can be 6y+7y and if u solve it would be 13y

Answer:

Volume of cylinder V= bh= 78 cm^3, where b is area of base(circle). Then volume of cone = 1/3bh =1/3*78 = 26 cm^3

Thanks!

Mark me brainliest!

Answer:

Volume (cone) = 26 cm³

Step-by-step explanation:

Given :-

Volume (cylinder) = 78 cm³

To Find :-

Volume (cone) with same height and radius

Solving :-

Find the equation for the volume of the cylinder.

πr²h = 78 cm³

But we know the volume of a cone is 1/3 of the volume of a cylinder.

=> Volume (cone) = 1/3 x 78

=> Volume (cone) = 26 cm³

Answer:

[tex]y=\frac{1}{3}x-2[/tex]

Step-by-step explanation:

Given the information, we can use the point-slope form to find the equation for the line:  [tex]y-y_{1}=m(x-x_{1})[/tex]

[tex]y-(-4)=\frac{1}{3}x(x-(-6) )[/tex]

Isolating y and combining like terms gives us [tex]y=\frac{1}{3}x-2[/tex]

Step-by-step explanation:

5(0)+1=1 because 5x0=0 then add the 1

The value of the function f (x) = 5x + 1 at x equal to zero will be 1.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable. Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The given function is f (x) = 5x + 1. The value of the function at x equal to 0 will be calculated as below:-

f (x) = 5x + 1

f (0) = 5 x 0 + 1

f (0) =  0 + 1

f (0) = 1

Therefore, the value of the function f (x) = 5x + 1 at x equal to zero will be 1.

Answer: x = 24

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Remove parentheses.

12 (2 − 2) + 32 = [tex]x[/tex] + 6 + 2

Step 2: Simplify 2 − 2 to 0.

12 × 0 + 32 = [tex]x[/tex]  + 6 + 2

Step 3: Simplify 12 × 0 to 0.

0 + 32 = [tex]x[/tex] +  6 + 2

Step 4: Simplify 0 + 32 to 32.

32 = [tex]x[/tex] + 6 + 2

Step 5: [tex]x[/tex] + 6 + 2 to [tex]x[/tex] + 8.

32 = [tex]x[/tex] + 8

Step 6: Subtract 8 from both sides.

32 − 8 = [tex]x[/tex]

Step 7: Simplify 32 − 8 to 24.

24 = [tex]x[/tex]

Step 8: Switch sides.

[tex]x[/tex] = 24
