the slop of (10,8) and (1,9)

The expression for the total cost is 75 + 22h

From the information, the plumber charges a flat fee of 75 to visit a home and examine a clogged drain and also charges an additional 22 per hour spent fixing the drain.

Therefore, the amount that will be charged for each hour will be:

= 75 + (22 × h)

= 75 + 22h

where h = number of hours.

For example if the number of hours is 5 hours. This will be:

= 75 + 22h

= 75 + 22(5)

= 75 + 110

= 185

The probability that, before the low fuel light comes on the car will travel is 0.2576

Given,

The average number of miles driven on a full tank of gas before its low fuel light comes on is ( μ )= 320

It follows the standard deviation of ( δ ) = 30

For the normal distribution,

P(X < x) = P( Z < x - μ / δ)

a)

P( X < 330) = P( Z < 330 - 320 / 30)

                   = P( Z < 0.3333)

                   = 0.6306

b)

P( X > 308) = P( Z > 308 - 320 / 30)

                  = P( Z > -0.4)

                  = P( Z < 0.4)

                  = 0.6554

c)

P( 305 < X < 325) = P( X < 325) - P( X < 305)

                             = P( Z < 325 - 320 / 30) - P( Z < 305 - 320 / 30)

                             = P( Z < 0.1667) - P( Z < -0.5)

                             = 0.5662 - ( 1 - 0.6915)

                             = 0.2576

Answer:

7

Step-by-step explanation:

Let x be the "integer."  We'll assume it is odd.

The next consecutive odd integer would be x+2.

(2(x+2) - x) =9    [When an integer is subtracted from 2 times the next consecutive odd integer the difference is 9]

(2(x+2) - x) =9

(2x+4) - x) =9

x+4 =9

x = 5

The greater integer is x+2 or 7

Check:

If 5 is subtracted from 2 times the next consecutive odd integer, 7, is the difference 9?

2*7 - 5 = 9?

14 - 5 = 9?

14 - 5 = 9?  YES

We need to know about scaling of measurements to solve the problem. The length of the bird's beak is 5.29 inches.

In the given question we know that the height of the bird in the photo is 3.4 inches and the real height of the bird is 3.75 feet. We know that the length of the beak in the photo is 0.4 inches, we need to find out the real length of the beak. We need to find by how much the measurement of the bird is scaled down to fit in the photo. We need to convert feet to inches first to get the scaling factor, we can then divide the length of the beak given by the scaling factor.

3.75 feet= 3.75x12 =45 inches

scaling factor= 3.4/45=0.0756

real length of beak=0.4/0.0756=5.29 inches

Therefore the length of the beak of the bird is 5.29 inches.

Define Trigonometric functions

A right-angled triangle's angle can be related to side length ratios using real-world trigonometric functions.

We know the formula of sin(A - B) = sinAcosB - cosAsinB

And the given expression is

sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12)

Which is in the form of given formula of sin(A - B)

where,  A = π/12  and B = 7π/12

put A and B values in sin(A - B),

sin(π/12 - 7π/12) =  sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12)

sin(-6π/12) =  sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12)

sin(-π/2) =  sin (π/12)cos(7π/12) -cos(π/12)sin(7π/12)

In the question ,

it is given that

the coordinates of the end points of A and B is A(-1,2) and B(5,8) .

also AC = 2/3(AB)

So , AC/AB = 2/3

Answer: y=x/3 + 4

Step-by-step explanation:

The coordinates of the rotated triangle will be (2, - 2) , (3, -8) , (7, 0)

Function translation takes a function (and its graph) and, by adding and subtraction, moves the graph around the plane without changing its shape.

Given is a triangle coordinate on x - y plane.

The rule (x, y) → (- x, - y) represents the rotation of a figure by 180 °.

Now, initially the coordinates of the triangle are -

(-2, 2) , (-3, 8) , (-7, 0)

After transforming the graph by the rotation of 180°, the new coordinates will be -

(2, - 2) , (3, -8) , (7, 0)

Plot the coordinates on the graph and you will get the rotated image.

Therefore, the coordinates of the rotated triangle will be (2, - 2) , (3, -8) , (7, 0).

we get that:

so the answer is x=-6

Answer:  m=1/5

Step-by-step explanation:

t(x) = x² + 8x - 20

Coordinate(s) of the solutions/roots

x² + 8x - 20 = 0 ==> (x -2)(x + 10) = 0

roots: x= 2 and x = -10

coordinate of the y-intercept

y-intercept is when x = 0 ==> t(x) = x² + 8x - 20 when x = 0: t(0) = -20

y-intercept: y = -20

location of the line of symmetry

x = -4

y = (x + 4)² - 36, therefore coordinates of the vertex (-4, 36) and line of symetry x = -4

coordinate of the vertex

Answer:

B

Step-by-step explanation:

before finding the sum we require to find first term and common difference.

the nth term of an AP is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

given a₁₀ = - 5 and a₁₅ = - 7 [tex]\frac{1}{2}[/tex] = - 7.5 then

a₁ + 9d = - 5 → (1)

a₁ + 14d = - 7.5 → (2)

subtract (1) from (2) term by term to eliminate a₁

0 + 5d = - 2.5

5d = - 2.5 ( divide both sides by 5 )

d = - 0.5

substitute d = - 0.5 into (1) and solve for a₁

a₁ + 9(- 0.5) = - 5

a₁ - 4.5 = - 5 ( add 4.5 to both sides )

a₁ = - 0.5

the sum to n terms of an AP is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

here a₁ = - 0.5 and d = - 0.5 , then

S₂₀ = [tex]\frac{20}{2}[/tex] [ (2 × - 0.5) + (19 × - 0.5) ]

      = 10 (- 1 -9.5)

     = 10 × - 10.5

    = - 105

The proof of (g/n)/(g/m) isomorphic to g/m from the first isomorphism theorem is as shown below.

Let a group g with normal subgroups m and n. Furthermore, n is a subset of m.

Proof: We have to prove (g/n)/(m/n) ≅ g/m           (1)

g/m and g/n are valid because m and n are normal in g. As normality satisfies the intermediate subgroup condition, n is normal in m. because normality is image-closed m/n is a normal subgroup in g/n. Under the quotient map by n, the normal subgroup m of g is sent to a normal subgroup m/n of g/n. Thus the L.H.S of the statement to prove makes sense.

To describe the isomorphism from the left side to the right side

φ: g/n \to g/m

ψ(gn) = gm

So, a coset of n is taken by the map and it gives the corresponding coset of m. This is well-defined, because if h∈ n, thus h∈ m, hence (gh)m = g(hm) = gm.

The map is a homomorphism. So we observe that it maps the identity element to the identity element, keeps group multiplication preserved, and also preserves the inverse map.

Also, the map is surjective because any coset gm is present as the image of gn under ψ.

Lastly, we need to find the kernel of the map which is given by the set of gn such that gm = m. This is those cosets of n that are in m, and this is the same as the coset space m/n. Thus the kernel of the map is exactly g/m. Thus, the surjective homomorphism ψ: g/n → g/m has kernel m/n. And now by the first isomorphism theorem

(g/n)/(m/n)≅g/m     where ≅ shows isomorphism

Answer:

y = 4x - 1.5

Step-by-step explanation:

We need to find the slope (m) and the y-intercept (b), if we are writing this in the slop intercept form of a line.

y =mx + b

The slope is the change in y over the change in x.

The two points give us the y's ad x's

The y's are: -1.5 and 2.5

The x's are: 0 and 1

[tex]\frac{-1.5 - 2.5}{0-1}[/tex] = [tex]\frac{-4}{-1}[/tex] = 4  A negative divided by a negative is a positive.

We have the slope.  The slope is the point (0,b).  We are given that point.

(o, -1.5)  The y-intercept is -1.5

y =mx + b

y = 4x - 1.5

Plug in the values in the right positions. And simplify.
