the y-intercept is (0,12)
the axis of summer is x=4
the vertex is ( , )

f(x)=x^2-8x+12

Answer:

38°

Step-by-step explanation:

1. Angles subtended at the circumference is half at the centre. Therefore angle at the centre is 61x2=122

2. Isosceles triangle have equal base angle. 19°

3. Tangent subtends 90° with the radius.

4. 90-19=71

5. 71x2=142°

6. Angles in a triangle add up to 180°

180-142=38°

Answer:

108°

Step-by-step explanation:

Answer:

9. (1/3)

10. (0, -2)

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

Step-by-step explanation:

(x₁, y₁) and (x₂, y₂)

(-3, -3)        (0, -2)

9.      

        y₂ - y₁         -2 - (-3)      -2 + 3         1

m = ------------ = ------------ = ------------ = -------

        x₂ - x₁         0 - (-3)        0 + 3         3

10.

y = (1/3)x - 2

y = -2

y-intercept: (0, -2)

11.

y - y₁ = m (x - x₁)

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

y + 3 = (1/3) (x + 3)

y + 3 = (1/3)x + 1

    -3              -3

y = (1/3)x - 2

I hope this helps!

What is Gravitational potential energy?

The gravitational potential energy of an object is given by:

U = mgh

where,

m is the mass of the object.

g is the acceleration of gravity.

h is the height of the object.

Given that;

The potential energy = 100 J,

In this problem, we have;

The potential energy of the person is = U = 100 J

The mass of the person = m = 80 kg

Now, Solving for h, we find at what height the person is:

h = U /mg

h = 100 / 80*9.8

h = 12.8 cm

Hence, The height of the hill is 12.8 cm.

the extraneous solution for the equation √(2 x +9) - √x = 3 is x = 0 or x = 6.

We are given an equation:

√(2 x +9) - √x = 3

√(2 x +9) = 3 + √x

Raise both sides to the power 2, we get that:

2 x + 9 = 9 + x + 6√x

x = 6√x

Squaring both sides again, we get that:

x² = 6 x

x² - 6 x = 0

x ( x - 6) = 0

x = 0 or x = 6.

Therefore, we get that, the extraneous solution for the equation √(2 x +9) - √x = 3 is x = 0 or x = 6.

The regular price of the sofa if 66% is given off, is $680.00

What is regular price?

The regular price of the sofa is the price at which it is sold without considering the coupon of 66%, in essence, it is 100% of the original price of the sofa, in short, if 66% is given off, then the sale price is 34% of the original price

34% of regular price=$231.20

1% of regular price=231.20/34

1% of regular price=$6.80

100% of regular price=$6.80*100

100% of regular price=$680

Step-by-step explanation:

You want the annual interest rate that results in an investment of $6000 growing to a value of $7351.81 in 5.5 years, when the interest is compounded monthly.

The value of an account in which principal P is invested for t years at annual rate r compounded n times per year is ...

  a = P(1 +r/n)^(nt)

For this problem, we have ...

These values make the equation be ...

  7351.81 = 6000(1 +r/12)^(12 ·5.5) . . . . . . equation with given values

  (7351.81/6000) = (1 +r/12)^66 . . . . . . . . divide by 6000

  (7.35181/6)^(1/66) = 1 +r/12 . . . . . . . . . . rewrite fraction, take 66th root

  (7.35181/6)^(1/66) - 1 = r/12 . . . . . . . . . subtract 1

  (12)((735181/6)^(1/66) -1) = r ≈ 0.03700003

The interest rate is about 3.7%.

The given equation is 8p + 4 = −9 + 7p.The value of p is -13.

The required solution for the given equation is p = -13

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1.There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.

Now the given equation is,

8p + 4 = −9 + 7p

Answer:

aₙ = 2aₙ₋₁  for n ≥ 2
a₁ = 3

Step-by-step explanation:

A geometric sequence can be expressed recursively using the following general equation

aₙ = r . (aₙ₋₁), n ≥ 2
where
aₙ is the nth term
a₁ is the first term of the geometric sequence

r is the common ratio = aₙ/aₙ₋₁

Here we have the terms 3, 6, 12, 24, 48

The common ratio r = 6/3 = 12/6 = ....... = 48/24 = 2

The first term a₁ =  3

So the recursive relation is
aₙ = 2aₙ₋₁  for n ≥ 2
a₁ = 3

Step-by-step explanation:

Value for f(x)  = x² - 12x + 35

Given :

             (f⁰g)(x) = x²-6 x+8

                 g(x) = x-3

Now ,

            (f⁰g)(x) = f(g(x))

         x²-6 x+8 = f(x-3)

let x = x-3

              f(x)  = (x-3)² - 6(x-3) + 8

              f(x)  = x² + 9 - 6x - 6x + 18 +8

              f(x)  = x² - 12x + 35
