How much money did she put into savings?

Answer:

70-45=25

70-25=45

Step-by-step explanation:

45+25=70

forty-five plus twenty-five equals seventy because if you ignore the fives and save those for later you will have forty and twenty and forty and twenty makes sixty and then you bring back the fives and add those together and get ten, then you add ten to sixty and you get seventy.

Step-by-step explanation:

A quadrilateral has 4 sides and 4 angle.

The sum of the 4 angles need to equal 360 degrees.

4th angle = 360 - 25-40-90

4th angle = 205 degrees.

Answer: Minimum of 13 balls

Step-by-step explanation:

If the gym teacher has $200 to spend and each ball costs a minimum of $15, she can buy:

= 200/15

= 13.3

= 13 balls

This is a minimum number as some balls might be more expensive than $15.

Answer:

this is a required answer.

The given identity is proved.

Trigonometric Identities are the equalities that involve trigonometry functions and holds true for all the values of variables given in the equation

According to the given question we have a trigonometry identity.

[tex]cos(x)cos(y)[tan(x)+tan(y)] = sin(x+y)[/tex]

To prove the above the identity, we show that R.H.S = L.H.S

So,

[tex]L.H.S = [cos(x)cos(y)][tan(x)+tany(y)][/tex]

[tex]\implies L.H.S = [cos(x)cos(y)][\frac{sinx}{cosx} +\frac{siny}{cosy} ][/tex]

[tex]\implies L.H.S = [cos(x)cos(y)][\frac{sinxcosy+sinycosx}{cosxcosy} ][/tex]

[tex]\implies L.H.S = cos(x)cos(y) \frac{sin(x)cos(y)+sin(y)cos(x)}{cos(x)cos(y)}[/tex]

[tex]\implies L.H.S = sin(x)cos(y)+ sin(y)cos(x)[/tex]

[tex]\implies L.H.S = sin(x+y)...(i)[/tex]

And from the given trigonometry identity,

[tex]R.H.S = sin(x+y)..(ii)[/tex]

Therefore,

L.H.S = R.H.S

⇒ [tex]cos(x)cos(y)[tan(x)+tan(y)] = sin(x+y)[/tex]      (proved)

Hence, the given identity is proved.

Answer:

Step-by-step explanation:

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)

in this exercice : x1 = 3  and  y1 =2

let  A(3,2)    B(-9,6)

the slope is : m =   (YB - YA)/(XB -XA)

(6-2)/(-9-3)  =4/(-12)  = -1/3

the slope is   m = -1/3

The equation is :  y – y1 = m(x – x1)

y-2 =-1/3 ( x-3)

or : 3y-6 = -x+3

The equation of the line that represents the line passing through the points (3, 2) and (-9, 6) is y=(1/-3)x+3.

The equation of line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is constant.

The slope of the line passing through the points is (3, 2) and (-9, 6) is,

[tex]m=\dfrac{6-2}{-9-3} = \dfrac{4}{-12} =\dfrac{1}{-3}[/tex]

The general equation of a line is y=mx+c, now substitute any point in the equation to know the value of the constant c,

[tex]y=mx+c\\\\2=\dfrac{1}{-3}(3)+c\\\\2=-1+c\\\\2+1=c\\\\c=3[/tex]

Hence, the equation of the line that represents the line passing through the points (3, 2) and (-9, 6) is y=(1/-3)x+3.

Answer:

Meter is the answer as per the question

The Options A and B given are correct. Based on trigonometric identities,

A) (cos A)(tan A) = sin A is correct.

B) tan B = [tex]\dfrac{sinB}{cosB}[/tex] is correct,

C) cos A = sin(90° - B) is incorrect.

Trigonometry is a mathematical concept that is responsible for the dealings of the relationships between the angles and sides of triangles.

In the given triangle ABC, ∠A is greater than ∠B.

A) Given that

(cos A)(tan A) = (cos A)([tex]\dfrac{sinA}{cosA}[/tex])

                      = sin A.

B) In the triangle ABC,

tan B = [tex]\dfrac{AC}{BC}[/tex]

By dividing the numerator and denominator by AB,

tan B = [tex]\dfrac{\frac{AC}{AB} }{\frac{BC}{AB} }[/tex],

tan B = [tex]\dfrac{sinB}{cosB}[/tex].

C) cos A = sin(90° - A) which is not as same as the equation in option C.

Thus, it is proven that options A and B are TRUE.
