Simplify this expression. 11 12 + (− 3 5 ) A) − 17 60 B) 18 55 C) 19 60 D)

Solution :

Trigonometry is that branch of mathematics which is used to study the relationship between the angles and the lengths of the sides of a triangle.

We known that the co-ordinate of a point on the circumference of a circle making an angle θ with the horizontal having a unit radius is given by :

(1 cos θ, 1 sin θ).

And for any angle made by sin θ on the x - axis is 0 and on the y -axis is 1 or -1 depending on the quadrant.

Since, angle 270 degree falls on the 3rd quadrant, therefore, the value of the co-ordinates of the point is (cos θ, sin θ) = (0,-1).

So the value of sin 270° = -1.

One other example of sin θ = 1 is 90° as 90 degree falls in the first quadrant.

Step-by-step explanation:

33 1/3%=100/3%

A percent as a decimal is percentage divided by 100

(100/3)/100=1/3

Since 1/3 of a number is 24 we can say

n/3=24

n=72

So 24 is 33 1/3% of 72

Answer:

D

Step-by-step explanation:

They just proved that m< 3 =m< 7 and m< 4=m< 8

So if m< 8=m< 5 and m< 7=m< 6

You can plug in m<5 for m< 8 and m<6 for m<7

Therefore:

m<6=m<3

m<5=m<4

Also, the angles that were proved congruent were vertical angles so the theorem they put works

Answer:

The vertex of the graph is (-3,1)

Step-by-step explanation:

Here, we want to rewrite the given quadratic equation in the vertex form

We have the vertex form as;

y = a(x-h)^2 + k

where the vertex is (h,k)

Now, by completing the square, we have to divide the coefficient of x by 2, then square; after which we add to both sides; prior to this, we have to replace y by 0

Thus, we have it as follows;

x^2 + 6x + 10 = 0

x^2 + 6x + 10 + 3^2 = 3^2

x^2 + 6x + 19 = 9

x^2 + 6x + 9 = 9-10

(x + 3)^2 = -1

(x + 3)^2 + 1 = 0

So we have the vertex as ;

(h,k) = (-3,1)

Answer:

For the first part of 4 questions wrong: he would get 42 points

For the second part 48 points

Step-by-step explanation:

For the first part of 4 questions wrong: he would get 42 points because 50 divided by 2 is 25 and 25 minus 4 is 21 and 21 times 2 is 42.

For the last part I'm guessing x = 1 so again 50 divided by 2 is 25 and 25 minus 1 is 24 and 24 times 2 is 48

I think it is right.

Answer: first one 42

The second one is 50-2x

explanation: score with 4 questions wrong

Available points 50. Points lost=points per question x4=2x4=8 final score 50-8=42

Score with x questions wrong: available points 50 points lost=points per questionx4=2*x=2x final score =available points-points lost =50-2x

Answer:

D) The account balance increases by an additional $100 for each deposit

Step-by-step explanation:

The y intercept will always be the number being added or subtracted from the independent variable.

The y intercept of y = 75x + 100 is 100, it means that the starting savings account balance is $100.

A linear equation is in the form:

y = mx + b

Where m is the rate of change and b is the y intercept.

Given the equation:

y = 75x + 100

The y intercept is 100, it means that the starting savings account balance is $100.

65-50= ∠2

15°=∠2

Step-by-step explanation:

Answer:

d. 15 degrees

Step-by-step explanation:

You're basically trying to find angle DBC. Adding 115 and 50 will give you 165. This means that angle DBC must be 15, as the angles have to add up to 180. Angle 2 and angle DBC are equal, so angle 2 is 15 degrees.
