Step-by-step explanation:

Let's verify all the options.

Option A:

Option B:

Option C:

Option D:

This has to be true because this triangle is classified as an equilateral triangle, which is a triangle.

Hence, Option A, C, and D are correct.

Answer:

A. 5 B. 3,5

Step-by-step explanation:

A. (h/g)(4) means h(x)/g(x) where x=4, so you would set up the equation as (x-9)/(x-3)*(x-5), then plug in 4 for all your x values.

Doing this you get (4-9)/(4-3)*(4-5), simplifying this you get -5/(1*(-1)=5

B. 3 and 5 are the values not in the domain because when you plug them in for you x values you would get a 0 in the denominator.

For example, when you plug in 3 for x, you get -6/(0*-2)=-6/0

This gives you a 0 in the denominator which you can not do

Answer: 72 cm

Step-by-step explanation:

The diameter is twice the radius, in other words just multiply the radius by 2.

36*2= 72 (You could also just add 36 to itself). I hope this helps!

Step-by-step explanation:

Given that

From the figure :

m angle 1 = 48°

Let m angle 2 = x°

And it is clearly m angle 1 and m angle 2 = 90°

90° = m angle 1 + m angle 2

Substitute the above values in equation then

⇛90° = 48°+x°

Shift the constant 50 from RHS to LHS, changing it's sign.

⇛ 90°-48° = x°

⇛42° = x°

⇛ x° = 42°

Therefore, m angle 2 = 42°

Answer: Hence, the value of m angle 2 is 42°

Additional comment:

The sum of the two angles is 90° then they are Complementary angles. The Complementary angle of x° is (90-x)°

A function assigns the value of each element of one set to the other specific element of another set. It can be concluded that the function in the table is a quadratic function and can be modelled as y=x².

A function assigns the value of each element of one set to the other specific element of another set.

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.

The given function is the table if closely observed is a quadratic function. This can be modelled by the equation, y= x²

To check if its a quadratic function or not, substitute the value in the formed function,

y= x²

4 = (-2)²

4 = 4

y= x²

0 = 0²

0 = 0

y= x²

4 = (2)²

4 = 4

y= x²

16 = (4)²

16 = 16

y= x²

36 = (6)²

36 = 36

Hence, it can be concluded that the function in the table is a quadratic function and can be modelled as y=x².

Answer:

y = 1/4x - 1 1/2

Step-by-step explanation:

(-6, -3) (2,-1)

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

x = -6 - 2   = -8 = 4

y = mx + b

-1 = 1/4(2) + b

-1 = 1/2 + b

-1/2 -1/2

-1 1/2 = b

y = 1/4x - 1 1/2

The final equation is y equals one fourth x minus one and one half.

Answer:

20

Step-by-step explanation:

Camper=12

Counseler=20

20+4=24

24/2=12

20-5=15

15=3/4 of 20

12+8=20

Thus the counselor's age is 20 years.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

Add four years to my present age, the result will be two times my camper’s.

Five years ago my age was 3/4 of what hers will be in eight years.

The present age of counselor.

Add four years to my present age, the result will be two times my camper’s. then,

y +4 = 2x .....1

Five years ago my age was 3/4 of what hers will be in eight years.

[tex]\rm y - 5 = \dfrac{3}{4} (x + 8)[/tex] .....2

From equation 1 and 2

[tex]\begin{aligned} \rm 2x - 4 - 5 &= \dfrac{3}{4} (x + 8)\\8x - 36 &= 3x +24\\5x &= 60\\x &= 12 \end{aligned}[/tex]

Put the value of x in equation 2, then

y + 4 = 2x

y + 4 = 2 *12

     y = 24 - 4

     y = 20

Thus the counselor's age is 20 years.

the first thing we notice : the quadrilateral has 2 pairs of equally long sides with 2 angles being openly 90°.

so, we are dealing with a rectangle here.

we know that one pair of the sides (NK = LM) are 24 cm long.

and we know that KL:LM = 3:4.

that means that the pair KL = MN are the shorter sides of the rectangle. and their length is according to the ratio 3/4 of NK=LM.

3/4 × 24 = 18 cm

the area of that rectangle is therefore

18 × 24 = 432 cm²
