$40.00              4                         10

$40.00             8                         0

Let 'E' represents the dollars spends on salad and pizza.

'S' represents the bowls of salad, 'P' represents the slice of pizza

Cost of bowl of salad = $5.00

Cost of slice of pizza = $2.00

Equation represents dollars spends on salad and pizza is :

E = 5S + 2P

Equation representing P in terms of E and S is:

P = (1/2)(E - 5S)

If E = $40.00

Then to make equation true value of S and P for the table is:

E = $40.00

S = 0

40 = 5(0) + 2P

⇒P = 20

E = $40.00

S = 4

40.00 = 5(4) + 2P

⇒P = 10

E = $40.00

P = 0

40.00 = 5S + 2(0)

⇒S = 8

In table form:

Budget        Bowls of salad    Slice of pizza

$40.00              0                         20

$40.00              4                          10

$40.00              8                          0

Therefore, the equation representing total amount of money spend is

Answer: f(x) = (x+8)^(1/2) - 9 / 12

Step-by-step explanation:

To find f(x), we need to apply the steps given in the problem in the order they are presented.

First, we add 8 to the input value x. This step is represented by the term x+8.

Next, we take the square root of the result from step 2. This step is represented by the exponent (1/2) on the term x+8.

Next, we subtract 9 from the result of step 3. This step is represented by the term -9.

Finally, we divide the result of step 4 by 12. This step is represented by the division operator '/' and the denominator 12.

So f(x) is a function that takes the input x, adds 8, takes the square root, subtracts 9, and divides by 12.

Answer:

f(x) = [√(x + 8) - 9]/12

Step-by-step explanation:
The expression f(x) begins with ->

Step 1: x + 8
Step 2: √(x + 8)
Step 3: √(x + 8) - 9
Step 4: [√(x + 8) - 9]/12

The equation is now:
f(x) = [√(x + 8) - 9]/12

Based on the slope, which describes a linear equation, the rent payment of Kai in 2016, was $1,073.66.

A linear equation is an algebraic equation written in the form of y=mx+b.

A linear equation involves a constant and a first-order term, where m is the slope and b is the y-intercept.

Kai's rental payment in 2013 = $836

Kai's rental payment in 2022 = $1,549

Slope = Rise/Run

Rise (Difference in rent between the two periods = $713 ($1,549 - $836)

Run = (Difference in the years) = 9 (2022 - 2013)

Slope = $79.22 ($713/9)

Let the number of years between 2013 and the stated year = x

Run = 3 (2016 - 2013)

y = mx + b

Rent in x years = 836 + 79.22x

= 836 + 79.

= $1,073.66 (836 + 79.22(3)

Thus, solving the linear equation, Kai's rental payment in 2016 was $1,073.66.

In mathematical terms, the equation e^-2.5 = h states that the exponential value of -2.5 (e^-2.5) is equal to the variable h. To convert this equation into its logarithmic form, we can take the natural logarithm of both sides of the equation. The natural logarithm, represented by the function ln, returns the power to which e must be raised to obtain a given number.

So, taking the natural logarithm of both sides of the equation, we have:

ln(e^-2.5) = ln(h)

Since ln(e^x) = x, we can simplify the left side of the equation:

ln(h) = -2.5

Thus, the logarithmic equivalent of the equation e^-2.5 = h is ln(h) = -2.5.

The logarithmic equation ln(h) = -2.5 can be interpreted as follows: the natural logarithm of h is equal to -2.5. In other words, h is the result of raising e to the power of -2.5. To find the value of h, we can use the exponential function:

h = e^-2.5

Therefore, the original equation e^-2.5 = h and the logarithmic equation ln(h) = -2.5 are mathematically equivalent and can be used interchangeably.

It is worth mentioning that logarithms are used in many areas of mathematics and science, including engineering, finance, and physics. They allow us to simplify complex calculations and to solve problems that are otherwise difficult or impossible to solve.

Step-by-step explanation:

a scientific number like 8.14 × 10^-7 is simply a form of

a × b

all operations with scientific numbers base on this.

multiplication :

(a × b) × (c × d) = a × b × c × d

or any other combination, as multiplication is commutative.

e.g. a × c × b × d

if it helps with a better understanding and the combination of factors of the same base.

addition :

(a × b) + (c × d)

this cannot be simplified per se.

we need to bring factors of both terms to the same base in order to be able to add them.

so,

part A

the area of a rectangle is

length × width

so, we have

8.14 × 10^-7 × 3.6 × 10^-9

as explained above, to make this better visible we combine factors of the same base :

8.14 × 3.6 × 10^-7 × 10^-9

remember, when multiplying factors of the same base, we simply add the exponents :

10^-7 × 10^-9 = 10^(-7 + -9) = 10^-16

and

8.14 × 3.6 = 29.304

so, the total result is

29.304 × 10^-16 m²

part B

a scientific number has exactly one significant digit (not 0) in front of the decimal point, and all other significant digits after the decimal point.

so, what do we need to convert

29.304 × 10^-16

to that ?

we need to divide the left part by 10. but to keep the value of the total number unchanged, we then need to multiply the right part by 10. in other words, we multiply by 10/10.

and we get

2.9304 × 10^-15 m²

part C

the perimeter of a rectangle is

2×length × 2×width

2×8.14×10^-7 + 2×3.6×10^-9

the first step is easy : simplifying the multiplications by 2.

16.28×10^-7 + 7.2×10^-9

now, we can only add them, if there is the same factor in each term.

and the easiest way to get to that is a manipulation of the 10-factors.

let's bring 10^-7 to 10^-9. that means a division by 100. remember, we need to keep the overall value of the number. what, what we do to one factor we need to counter in the other factor :

16.28×10^-7 = 100/100 × 16.28×10^-7 =

= 100×16.28 × (10^-7)/100 =

= 1628 × 10^-9

now we can add both numbers

1628×10^-9 + 7.2×10^-9 = 1635.2×10^-9 m

part D

remember what we said in part B.

here now we need to divide the left part by 1000. which means we also need to multiply the right part by 1000.

1635.2×10^-9 × 1000/1000 = 1.6352 × 10^-6 m

Answer:

Ok

Step-by-step explanation:

The statement given is true. When the bisector of an angle of a triangle bisects the opposite side, the is the triangle isosceles.

In the attached picture of ΔABC, we can see that AD is the bisector of ∠A that meets BC in D, so that BD = DC.

Now, we need to prove that AB = AC.

As construction, produce AD to E so that AD = DE, and then join CE.

So, in ΔABD and ΔECD, we have:

BD = CD

AD = ED

and ∠ADB = ∠EDC because those are vertically opposite angles.

Consequently, based on SAS congruence criterion, ΔABD ≅ ΔECD.

Thus, AB = EC and ∠BAD = ∠CED. And also, ∠BAD = ∠CAD.

For that reason, it means ∠CAD = ∠CED, and AC = EC.

Hence, AB = AC. It is proved that the triangle is isosceles.

(a) The sum a + (a + 1) + (a + 2) + ... + (a + n - 1) is Sn = n/2 * (a + n)

It can be represented as the sum of an arithmetic series. The nth term of the series is (a + n - 1) and the first term is a.

The common difference between consecutive terms is 1. The formula to calculate the sum of an arithmetic series is:

[tex]Sn = n/2 * (2a + (n - 1)d)[/tex]

Where n stands for the number of terms, a will be the first term, and d is a common difference. By substituting the values for n, a, and d, we'll get:

Sn = n/2 * (2a + (n - 1) * 1)

Sn = n/2 * (2a + n - 1)

Sn = n/2 * (a + n)

(b) The pairs of positive integers (a,n) that will fulfill the conditions are (10,10), (15,8), and (20,6).

To find all pairs of positive integers (a,n) such that n is greater than 2 and a + (a + 1) + (a + 2) + ... + (a + n - 1) = 100, we can rearrange the formula from the above problem part (a) to solve for a:

Sn = n/2 * (a + n) = 100

a = 2 * (100/n) - n

Since a must be a positive integer, we can use trial & error to find all possible values of n that make a positive integer. Here are some of the solutions:

For n = 10, a = 10.

For n = 8, a = 15.

For n = 6, a = 20.

So the pairs of positive integers (a,n) that satisfy the conditions are (10,10), (15,8), and (20,6).

Nathan can cut 3 one-acre lawns with a full tank of gas

What is Cross multiplying fractions?

Cross multiply fractions by multiplying one fraction's denominator by the second fraction's numerator and then comparing the two values. The larger fraction is the one with the higher value.

Since Nathan's lawnmower uses one tank of gas to cut three one-acre lawns, it means that he can cut one one-acre lawn with 1/3 of a tank of gas. So, if he has a full tank of gas, he can cut one-acre lawns equal to the number of times 1/3 fits into a full tank. In other words, he can cut a full tank of gas divided by 1/3 of a tank of gas.

The number of one-acre lawns Nathan can cut with a full tank of gas is:

1 tank / (1/3 tank) = 3 one-acre lawns.

So, Nathan can cut three one-acre lawns with a full tank of gas.

the square of the measure of the tangent is equal to the product of the measures of the secant's external part and the entire secant, that is

TC × TB = TA²

3(3 + x - 2) = 6²

3(x + 1) = 36 ( divide both sides by 3 )

x + 1 = 12 ( subtract 1 from both sides )
