The slope would be undefined

Step-by-step explanation:

If the slope is perpendicular to the x-axis that means it is vertical, all vertical lines have undefined slopes therefore the slope is undefined.

The total number of miles that the teacher ran both last week and this week was 10.35 miles

Last week, the teacher ran a total of 5 3/4 miles. For easier calculation, convert this to a decimal:

= 5 + 3/4

= 5 + 3 ÷ 4

= 5 + 0.75

= 5.75 miles

This week, the teacher ran 4 / 5 of the miles he ran the previous week:
= 5. 75 x 4/5

= 4.6 miles

The total number of miles the teacher ran both last week and this week were:

= 5.75 + 4.6

= 10.35 miles

Answer:

10 7/20 miles

Step-by-step explanation:

The total cost is $12.74

In this question, we have been given the cost of 1 gallon of milk, 1 gallon of ice-cream and 1 1b of strawberry.

1 gallon of milk costs $2.48,

1 gallon of ice-cream costs $1.49

and 1b of strawberry costs $0.58

You buy 3 gallons of milk, 2 gallons of ice cream, and 4 lbs of strawberries.

So by unitary method total cost would be,

(3 * 2.48) + (2 * 1.49) + (4 * 0.58) = $12.74

Therefore, the total cost is $12.74

Using the Pythagorean Theorem, the approximately length of ladder is 20.6 feet

As we know Michael is standing on roof of his house.

He stands 5 feet away from his house

The ladder touches the point 20 feet above the ground and where the Michael standing

In this order we have to find the approximately length of ladder

From this question we can clearly figure out that in this question we have:

Perpendicular= 20 feet

Base = 5 feet

So as we can understand that we have to use Pythagorean Theorem

Pythagorean Theorem:

(Hypotenuse)^2 = (Perpendicular)^2+(Base)^2

(Hypotenuse)^2 = (20)^2+(5)^2

(Hypotenuse)^2 = 400+25

(Hypotenuse)^2 = 425

Hypotenuse=square root(425)

Hypotenuse=20.6 feet

Hence, the approximately length of ladder is 20.6 feet

So the option C is correct.

The amount of each semiannual interest payment is $7200.

Given that,
A company issues 9%, 4-year bonds with a par value of $160,000 on January 1 at a price of $165,386, when the market rate of interest was 8%. The bonds pay interest semiannually.

Simple interest is defined as the percentage of earnings on the lending for a period of time

Here,
Value of a single bond    =  $160,000
Issue price of bond         =  $165, 386
Rate of interest                =     9%
the market rate of interest =     8%
Interest payment             =      Semi-annually

Semi-annual interest payment      =  Value of the single bond × rate of interest/2
                                                       = $160,000 × 0.09/2
                                                       =  $7200

Thus, the amount of each semiannual interest payment is $7200.

The slope of the road is 159/53

What is a slope?

How steeply a line slopes from left to right is known as its slope. By dividing a line's rise, or vertical change, by run, or horizontal change, one can calculate a line's slope, the slope of a line is always constant (it never varies).

To calculate the slope of a line using the formula

m = rise / run = (y₂ - y₁)/(x₂ - x₁)

where, m = slope

(x₁, y₁) = coordinates of the first point in the line

(x₂, y₂) = coordinates of the second point in the line

Here, we have

rise = 795

run = 265

by using the slope formula,

m = rise/run

m = 795/265

m = 159/53

Hence, the slope of the road is 159/53.

A) The value of x in log₄(x² - 12x + 48) = 2, is x = 4 OR x = 8

B) The value of x in 27^(4x-6) =(1/9)^(2x-7), is x = 2

From the question, we are to solve the given equations

The given equation is log₄(x² - 12x + 48) = 2

From one of the laws of logarithm, we have that

logₐ x = n ⇒ x = aⁿ

Thus,

log₄(x² - 12x + 48) = 2 becomes

(x² - 12x + 48) = 4²

x² - 12x + 48 = 16

x² - 12x + 48 - 16 = 0

x² - 12x + 32 = 0

Solve the quadratic equation

x² - 12x + 32 = 0

x² - 8x - 4x + 32 = 0

x(x - 8) -4(x - 8) = 0

(x - 4)(x - 8) = 0

x - 4 = 0 OR x - 8 = 0

x = 4 OR x = 8

B) 27^(4x-6) =(1/9)^(2x-7)

Solve for x

27^(4x-6) =(1/9)^(2x-7)

Express the bases in index form

3^3(4x-6) =(3)^-2(2x-7)

Equate the powers

3(4x - 6) = -2(2x - 7)

12x - 18 = -4x + 14

12x + 4x = 14 + 18

16x = 32

Divide both sides by 16

16x/16 = 32/16

x = 2

Hence, the value of x is 2

a. The number of permutations of three letter words that can be formed with repetition is 1000 words

b. The number of permutations of three letter words that can be formed without repetiton is 720 words

Permutations are the number of ways in which x objects can be arranged out of n objects.

The number of permutations is given by ⁿPₓ = n(n - 1)(n -2)...(n - x + 1)

Since we require the number of three-letter "words" can be made from 10 letters "FGHIJKLMNO" with repetition, we note that there are 10 letters.

Since repetition is allowed, for the first slot, we have 10 letters, for the second position, we have 10 letters and for the third position, we have 10 letters.

So, the total number of permutations is n = 10 × 10 × 10

= 1000 words

So, the number of three letter words that can be formed is 1000 words

Since we require the number of three-letter "words" can be made from 10 letters "FGHIJKLMNO" without repetition, we note that there are 10 letters.

Since repetition is not allowed, for the first slot, we have 10 letters, for the second position, we have 9 letters and for the third position, we have 8 letters.

So, the total number of permutations is ¹⁰P₃ = 10 × 9 × 8

We know that a polynomial with leading coefficient a and the roots:

x₁, x₂, ..., xₙ

Can be written as:

p(x) = a*(x - x₁)*...*(x - xₙ)

Here we have the roots:

-3, -3, 2, 2, -2

Then we can write:

p(x) = a*(x + 3)*(x + 3)*(x - 2)*(x - 2)*(x + 2)

p(x) = a*(x + 3)²*(x - 2)²*(x + 2)

Now we also know that our polynomial passes through (0, 62), then:

62 = a*9*4*2

62/(9*4*2) = a

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° .

The given right-angle triangle has the following sides,

AC = Base

BC = Perpendicular

a) Length of Fence = 50 meters

b) Weight of Grass Seeds = 20 kg

c) Area of Carriageway = 516 sq. meters

d) Time taken by the Striping Car = 7.6 minutes

What is a Circle?

A circular plane figure with a circumference made up of points equidistant from a given point (the center).

Solution:

a) To calculate the length of fence we need to find the circumference of the inner circle

Circumference of Circle = 2*22/7 *Radius

Circumference of Circle = 2 * 22/7 * (16)/2

Circumference of Circle = 50.24

So, the length of fence is 50 meters approx

b) To calculate the the total weight of grass we need to first find the area of the inner circle

Area of Circle = 22/7 * (Radius)^2

Area of Circle = 22/7 * (16)^2

Area of Circle = 22/7 * 256

Area of Circle = 803.84 meter sq.

For 1 meter sq. = 25 grms of grass seeeds are required

So, for 804 meters = 25*804 = 20100 grams

20100 grams = 20.1 kg = 20 kg (approx)

c) The are of Inner Carriageway will be calculated by substracting the area of inner circle from outer circle

Area of Outer Circle = 3.14 * (16+4.5)^2

Area of Outer Circle = 1320 sq. meters (approx)

Area of Inner Circle = 804 sq. meters (approx) #we have calculated it above

Area of Carriageway = 1320 - 804 = 516 sq. meters (approx)

d) Speed of Stripping Car = 25 cm/sec

Circumference of the part to be stripped = 2*3.14*(16+2.25)

Circumference = 115 meters approx. = 11500 cm

Time = Distance / Speed

Time = 11500/25 = 460 seconds

What is simple interest?

The principal of a loan or the first deposit into a savings account serves as the basis for simple interest. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

P=$26,000  r=2.6%=0.026

A=2P=2(26,000)=$52,000

A=P+Prt

Substitute the known values

52,000=26,000+(26,000×0.026t)

A) It is an exponential equation.

C) The rate between days 2 and 4 is 6 minutes per station number.

Here we have the following data:

(1, 2), (2, 4), (3, 8), (4, 16)

What you can see is that the x-value of the points increases equially between consecutive pairs (increases of one unit).

while the y-value does not do that.

First, it increases by 2, then by 4, then by 8.

So this is an exponential relation.

B) A general exponential will be of the form:

y = a*(b)^x

Usin the first two pairs (1, 2) and (2, 4) we can write two equations:

2 = a*b^1 = a*b

4 = a*b^2

So we have a little system of equations:

2 = a*b

4 = a*b*b

If we take the second equation and we divide that by the first one we get:

4/2 = (a*b*b)/(a*b)

2 = b

Replacing that in the first equation we get:

2 = a*2

2/2 = a = 1

The equation is:

y = 2^x
