Step-by-step explanation:

the domain is the interval or set of all valid x values.

as we can see, the function goes continuously from all the way to the left (until all eternity to -infinity) all the way to the right (until all eternity to +infinity).

the domain is

-infinity < x < +infinity

the range is the interval or set of all valid y (function result) values.

we see, the lowest y value is -1. and then the function goes on both sides up, up, up in all eternity to +infinity.

the range is

-1 <= y < +infinity

f(x) is decreasing for

-infinity < x < -1

f(x) is increasing for

-1 < x < +infinity

Step-by-step explanation:

Converted from word to standard form.

The value of the equation 9 less than nine times a number is A = 9n - 9 , where n is the number

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 9 less than nine times a number

Let the number be represented as n

On simplifying the equation , we get

A = 9n - 9

Therefore , the value of A is 9n - 9

Hence , the equation is A = 9n - 9 , where n is the number

Answer:

See the picture below.

Step-by-step explanation:

The order of the numbers from greatest to smallest is the cube root of 37, 16 over 5, negative pi, and negative four and two thirds

The numbers we are to order from the greatest to the least are ∛37, 16/5, -4 2/3, -22/7. To ease the problem, all the numbers should be converted to decimal form.

A decimal is a number that consists of integers and non-integers. The integers are separated from the non-integers by a decimal point. An example of a decimal number is 1.23.

When converted to decimals, the number become:

∛37 = 3.33

16/5 = 3.2

-4 2/3 = -14/3 = -4.67

-22/7 = -3.14

The further away a positive number is from zero, the greater the number. The closer a negative number is to zero, the greater the number.

3.33, 3.2, -3.14, -4.67

The number of apples Maria has after giving 1 apple to Lillian at the end is is 5 apples.

Given data:

The expressions representing the change in values of the apples are:

Lilian starts with 12 apples, and she gives half (6 apples) to Sebastian. She now has 12 - 6 = 6 apples.

Sebastian starts with 6 apples and gives 2 apples to Jose. He now has 6 - 2 = 4 apples.

On simplifying the expressions:

Maria starts with 6 apples and gives 2 apples to Jose. She now has 6 - 2 = 4 apples.

Sebastian gives half of his remaining apples (4 / 2 = 2 apples) to Maria. Maria now has 4 + 2 = 6 apples.

Maria gives 1 apple to Lilian. She now has 6 - 1 = 5 apples.

Hence, at the end of the given actions, Maria has 5 apples.

Write the number as a fraction of 1 (one):

Simultaneously multiply the numerator and denominator by 10 as many times as the digits after the comma (separation between the integer part and the fractional part of the number):

Since we have 3 numbers after the comma, multiply the numerator and denominator by 1000. So,

Note that multiplying by 10 is the same as moving the decimal point one place to the right.

Once this fraction is irreducible, that is, it is in reduced form, we can no longer simplify it. The answer is the previous fraction.

Answer: 150,000,000

Step-by-step explanation:

Total percentage of editorial + engineering = 20%

Total budget of editorial + engineering = 30,000,000

So, Total budget*20/100 = 30,000,000

Total budget = 5*30,000,000

Total budget = 150,000,000

The amount of time he spent on bicycle is 4.5 hours.

Given Jim began a 145 mile bicycle trip.

The whole trip took 7 hours.

Jim walks at a rate of 4 miles per hour  and rides at 30 miles per hour.

speed = distance / time

time = distance / speed

ride:

d = distance ridden

t = d/30 (given from the problem)

walk:

t = (145 - d)/4 (given from problem)

total trip time:

7 = d/30 + (145 - d)/4.

7 = 4d/120 + 30(145 - d)/120

7×120 = 4d + 30(145 - d)

840= 4d +4350-30d

840 ₋ 4350 = ₋30d ₊ 4d

₋3510 = ₋26d

d = 3510/26

d = 135

d=135 then from here using the formula t = d / s we can solve

t=135/30 = 4.5 hours

hence the amount of time Jim spent on the bicycle is 4.5 hours.

Rate is R (speed)

It is now.

We can determine the individual distances for the two legs of the whole to determine the overall distance D.

Initial Leg:

R = 8

T = a

D = 8a

8(45 – b) + 7.5b =D

What is the formula for rate and distance?

Use the formula d = st to determine speed, distance, or time. Distance is equal to speed multiplied by time. Given two known numbers, the Speed Distance Time Calculator can solve for the unknown sdt value.

Units of seconds (s), minutes (min), hours (hr), or hours, minutes, and seconds can be used to input or solve for time (hh:mm:ss). Time format shortcuts are shown below.

Use the formula d = st, or distance equals speed times time, to find the distance.

Distance Equals speed x time

Since both reflect a certain amount of distance per unit of time, such as miles per hour or kilometers per hour, rate and speed are comparable. If speed s and rate r are equal, then r = s = d/t. The corresponding formula is d = rt, which denotes Rate times time are equivalent to distance.

Distance = Rate x Time

Use the speed formula, s = d/t, which states that speed is equal to distance divided by time, to solve for speed or rate.

speed equals distance/time.

Use the time formula, t = d/s, which states that time is equal to distance divided by speed, to solve for time.

The distance between the starting point(initial) and the ending point(last) is known as displacement is  9.46miles.

What is displacement?

In the first(1st) part of the race displacement of Erica is

d1 = 5.2 miles at 25(twenty-five) deg North of East

x(ax) and y-component of 1st(first) part of the race will be:

d1 = 5.2*cos 25(twenty five) deg i + 5.2*sin 25(twenty five) deg j

d1 = (4.71 i + 2.20 j) miles (this id d1)

In the second(2nd) part of the race

d2 = 6(six) miles towards north,

So

d2 = (6 j) miles (this is d2)

Now net(accurate) displacement of Erica will be, Using Vector addition(summation):

d = d1(4.71 i + 2.20 j) + d2(6j)

d = (4.71 i + 2.20 j) +(sum) (6 j)

d = 4.71 i +(sum) 8.20 j

So Magnitude of net(accurate) displacement will be:

|d| = [tex]\sqrt{4.71^2+8.20^2}[/tex]

|d| = 9.46 miles(nine.four-six) = distance between starting(initial) point and ending point

The coordinates of point E is (-37/7, 23/7)

The formula for calculating a coordinate points using the points (-1, -1) and point A is located at (-7, 5) in the ratio 2:5 is expressed as:

E (x, y) = {(ax₁+bx₂)/a+b, (ay₁+by₂)/a+b}

Substitute the coordinates and ratios to have;

E (x, y) = {(2(-1)+5(-7))/2+5, (2(-1)+5(5))/2+5}

E(x, y) = {-35-2/7, -2+25/7}

After the tax return percent is 7.43%.

What is a tax return?

The tax-return of the corporation will be calculated by providing a 70% of deduction to the preference dividend.

The total amount of preference dividend which will be taxable= (dividend amount*(1-.7)

= (4*.3)= 1.20.

The total amount of tax= (total preference dividend taxable*x tax rate)

= (1.2*.3)=.36

The total after tax amount of Return= (preference dividend-tax)= (4-.36)= 3.64.

There will be no capital gain because there is no change in the price of preference shares.

After tax return=(after tax dividend/purchase price)

= (3.64/49)

= 7.43%.

Step-by-step explanation:

let the number of wholewheat bread batches be x

let the number of muffin batches be y

prep condition: 4x + (1/2)y ≤ 16 or 8x + y ≤ 32

baking condition : 1x + (1/2)y ≤ 10 or 2x + y ≤ 20

graph each of those in the first quadrant shading in the region below each one.

Final shading is the region satisfying both conditions.

profit = 35x + 10y

allow this line to "slide" away from the origin as far as you can.

It should be clear that the farthest we can go is the intersection of

8x+y = 32 and

2x + y = 20 or the x and y intercepts of our two boundary lines.

subtract them as they are:

6x = 12

x = 2

then in our head , y = 16

max profit = 2(35) + 10(16) = 230

Just to make sure, I will test the intercepts of our intersecting region, namely (4,0) and (0,20)

for (4,0) profit = 4(35)+1 = 140

for (0,32) profit = 0 + 10(20) = 200

so max profit is 230 when x=2 and y=16

(notice all the prep time and baking time is utelized)
