Can Someone Help Me On This?

Answer 1

Answer:

Step-by-step explanation:

We know that cosx = sin([tex]\pi[/tex] - x)

We can apply it here:

sin(55°) = cosx

cos([tex]\pi[/tex] - 55°) = cosx

Now we apply the arccos to both sides:

x = [tex]\pi[/tex] - 55° + 2k[tex]\pi[/tex] or x = -[tex]\pi[/tex] - 55° + 2k[tex]\pi[/tex]

Tell whether the ordered pair (5,-6) is a solution of the system of linear equations. 6x+3y=12 4x+y=14

Answers

Answer:

Yes, it is a solution.

Step-by-step explanation:

We can plug in the ordered pair (5, -6) for the x and y values:

6(5)+3(-6)=12

30-18=12

4(5)-6=14

20-6=14

The ordered pair (5, -6) is a solution of the linear equations.

find the lcm of 150 and 180

Answers

The answer would be 900

the answer is 900 because

LCM(150,180) = (150 × 180) / GCF(150,180)

= (150 × 180) / 30

= 27000 / 30

= 900

Therefore,

LCM(150, 180) = 900

The Degree = 6(even), leading coefficient = -4 (negative).

and, behavior End  Both ends of the graph goes down(In the same direction)

What is end behavior of a function?

The behavior of the function graph at the "ends" of the x-axis is known as the end behavior of a function. In other words, if we look at the right end of the x-axis (as x approaches +∞) and the left end of the x-axis (as x approaches −∞), the end behavior of a function represents the trend of the graph.

Given function, P(x) = −[tex]4x^6[/tex]+ [tex]2x^5[/tex]− 8x − 15.

Here, Degree = 6(even), leading coefficient = -4 (negative).

Additionally, a function's degree and leading coefficient, or the coefficient of the highest degree monomial, reveal the final behaviour of its graph.

If the leading coefficient is negative and the degree is even, the behavior of the function f(x) is, Both ends of the graph goes down(In the same direction)

There are several proofs in geometry

The statements that complete the proof are:

Converse of isosceles triangle theorem.Hin ge theorem

The proof of GE = OE

Considering triangle GED, the angles at G and E are congruent;

This means that: triangle GED is an isosceles triangle.

So, sides GE and OE are congruent by the converse of isosceles triangle theorem

The proof of [tex]\angle AEG > \angle TEO[/tex]

Considering triangles AEG and TEO, where GE = OE

Angle AEG is greater than angle TEO.

This is so because, the Hin ge Theorem states that given that the two sides of two different triangles are congruent and the angle included is different, then the larger angle is at the opposite of the longer side.

Hence, the statements that complete the proof are:

A. 75.4
B. 53.8
C. 37.8
D. 8.6

Answers

Answer:

C

Step-by-step explanation:

538.6 - 75.4 = 463.2

538.6 - 53.8 = 484.8

538.6 - 8.6 = 530

C is closets to 500 so it has to be 500.8

I'm ordering pizza for a party and want to make sure that I get the most pizza for my money. below pictures, which option should I choose to get the most pizza. (Hint: A = nr2?) Show your work! One 18 inch Large Pizza Two 12 inch Medium Pizzas OR 12 inches 12 inches 78 inches​

Answers

Answer:

one 18" pizza contains more pizza than 2 12" pizzas

Step-by-step explanation:

area of 12" pizza:

A = πr²

A = (3.14159)(6 in.)²

A = 113 in.²

two 12" pizzas have a total area of 226 in.²

area of 18" pizza:

A = πr²

A = (3.14159)(9 in.)²

A = 254 in.²

one 18" pizzas has a total area of 254 in.²

P.S. This problem is poorly worded. Above it states "... want to make sure I get the most pizza for my money." Since there is no indication of price for either option, two 12-inch pizzas or one 18-inch pizza, we cannot calculate what the most pizza for the money is. Below it states "which option should I choose to get the most pizza?" Here it no longer asks for most pizza for the money. Now it just asks for which option gives the most pizza.

Write an equation in slope-intercept form of the line that passes through (2,-3) and (- 1/2, 1/8)​

Answers

Answer:

[tex]y = - \frac{5}{4} x - \frac{1}{2} [/tex]

Step-by-step explanation:

Slope-intercept form: y= mx +c, where m is the slope and c is the y-intercept.

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

Slope

[tex] = \frac{ - 3 - \frac{1}{8} }{2 - ( - \frac{1}{2}) } [/tex]

[tex] = - \frac{5}{4} [/tex]

Substitute the value of m into the equation:

[tex]y = - \frac{5}{4} x + c[/tex]

To find the value of c, substitute a pair of coordinates the line passes through into the equation.

When x= 2, y= -3,

[tex] - 3 = - \frac{5}{4} (2) + c[/tex]

[tex] - 3 = - \frac{5}{2} + c[/tex]

[tex]c = - 3 + \frac{5}{2} [/tex]

[tex]c = - \frac{1}{2} [/tex]

Thus, the equation of the line is [tex]y = - \frac{5}{4} x - \frac{1}{2} [/tex].


i need help ASAP, if m<4 =35, find m<2 and m<3

Answers

Answer: m < 2 = 35 , m < 3 = 55

Solution: given figure AB and CD are PARALLEL to each other and BC is the transversal line.

m<4=m<2

since m < 4 = 35

Given figure it is clear that m < 1 = 90

Now*>ABC formed a triangle

M<1+m<2+m<3=180 degrees

Or 90 + 35 + m < 3 = 180 degrees

M < 3 + 125 = 180

M < 3 = 180 - 125

M < 3 = 55

EQUALS TO m < 2 = 35 degrees, m < 3 = 55 degrees
