The number in standard notation is 143,000.
The number in scientific notation is 4.39 x 10^-4
What is scientific and standard notation?
Scientific notation is used to compress large numbers into smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
For example:
• The number : 1 x 10² is equivalent to 100
• The number 5 x 10³ is equivalent to 500
When changing a number that is less than 1 to scientific notation, there would be a negative sign before the power.
0.000439 = 4.39 x 10^-4
In order to convert a number from scientific notation to standard notation, multiply the number by its power.
1.43 x 10^5
= 1.43 x 100,000 = 143,000

Limite de 2x^2+3x-9/x-1.5 cuando x 1.5

¿Es evitable la discontinuidad de una ecuación racional?
En este problema tenemos el caso de una ecuación racional cuyo numerador y denominador son polinomios.
La discontinuidad de la ecuación racional es evitable si y solo si tanto el numerador y el denominador tienen la misma raíz. La existencia de la discontinuidad evitable se comprueba mediante procedimientos algebraicos. En consecuencia, realizamos la siguiente comprobación:
f(x) = (2 · x² + 3 · x - 9) / (x - 1.5)
f(x) = [(x - 1.5) · (x + 3)] / (x - 1.5)
f(x) = x + 3
La discontinuidad es evitable y la función existe para x = 1.5, entonces:
f(1.5) = 1.5 + 3
f(1.5) = 4.5
El limite de f(x) = (2 · x² + 3 · x - 9) / (x - 1.5) cuando x = 1.5 es 4.5.

You are solving a measurement problem where the numbers 2.09*10^(9) and 4.053 × 10^−4 are divided. How many significant digits should the quotient have?
Answer:
3
Step-by-step explanation:
You want to know the appropriate number of significant digits in the quotient of measurements 2.09×10^9 and 4.053×10^-4.
Significant digitsThe number of significant digits in a number written in scientific notation is the count of digits in the mantissa. Numbers with more significant digits are considered to be more precise.
2.09×10^9 . . . . has 3 significant digits
4.053×10^-4 . . . . has 4 significant digits
Product or QuotientWhen imprecise numbers are multiplied or divided, the resulting product or quotient cannot be more precise than the least precise number used. The quotient of numbers with 3 and 4 significant digits will only have 3 significant digits.
Pam takes her truck in for basic service. The service agent says a few extra repairs are also needed, so Pam adds the cost of those repairs in her head, rounding to the nearest $10. The costs are as follows: Wheel alignment: $110 Transmission fluid flush: $75 Cabin air filter: $23 What is her total estimate for the repairs?
The total estimate for the repairs when Pam takes her truck in for basic service is $200.
How to illustrate the information?Based on the information given, the costs are as follows:
Wheel alignment: $110 = $100
Transmission fluid flush: $75 = $80
Cabin air filter: $23 = $20
Therefore, the total estimate for the repairs will be:
= $100 + $80 + $20
= $200
Therefore, the total estimate for the repairs when Pam takes her truck in for basic service is $200.

g(x) = 3x^2-2x+1
Find g(-2)
Answer: g(-2) = 17
Step-by-step explanation:
When finding g(-2), we will substitute all values of x for -2 in the function. First, we will substitute values in. Then, we will simplify by squaring, multiplying, and adding.
g(x) = 3x² -2x + 1
g(-2) = 3(-2)² -2(-2) + 1
g(-2) = 3(4) + 4 + 1
g(-2) = 12 + 4 + 1

Velma wants to buy a house that is listed for $195,000. Her bank offers a 30-year fixed-rate mortgage with an APR of 3.9%. What will her monthly house payment be?
Based on the amount that Velma wants to buy the house for and the fixed-rate mortgage offered by her bank, her monthly house payments will come to $919.75
What are the monthly house payments?The monthly house payments are constant so they are an annuity. The loan amount of $195,000 will be the present value of the annuity.
The monthly rate is:
= 3.9% / 12
= 3.9/12%
The number of periods is:
= 30 x 12
= 360 months
The monthly house payments is:
195,000 = Amount x (1 - (1 + 3.9/12%)³⁶⁰) / 3.9/12%
Amount = 195,000 / 212.01344311265715516703523151038

A travel agent receives a 6% commission on the base fare of a customer- that is, the fare before sales tax is added. If the total fare
charged to a customer comes to $787.91 including 5.5% sales tax, how much commission should the agent receive?
The agent will get $47.2746 for his commission.
What is the percentage?A percentage is a number or ratio expressed as a fraction of 100 in mathematics. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" is also used. A percentage is a number with no dimensions; it has no unit of measurement. To calculate a percentage, divide the value by the total value and multiply the result by 100. (value/total value)100% is the formula for calculating the percentage.
So, we have to take out 6% of $787.91 in order to obtain the commission of the agent.
Then,
787.91/100 × 67.8791 × 6$47.2746Therefore, $47.2746 will the agent get for his commission.

The speed limit in Canada is 100km/hr. What is the value of this limit in mi/hr given 1mi = 1.609km?
Answer:
62.14 miles per hour
Answer: 100 km/h is equal to 62.14 mph
So, 100 km/h is equal to 62.14 miles per hour.
Answer:
62.15 mi/hr
Step-by-step explanation:
Given:
1 mile = 1.609 kmAs both speed limits are given "per hour", we only need to convert 100 km to miles. To do this, set up and solve a ratio for "miles to kilometers", where x is the number of miles to 100 km:
[tex]\implies \sf 1 : 1.609 = x : 100[/tex]
[tex]\implies \sf \dfrac{1}{1.609} = \dfrac{x}{100}[/tex]
[tex]\implies \sf \dfrac{1}{1.609} \cdot 100= x[/tex]
[tex]\implies \sf x= \dfrac{100}{1.609}[/tex]
[tex]\implies \sf x= 62.15040398...[/tex]
Therefore, 100 km/hr = 62.15 mi/hr (2 d.p.)

what 2 numbers can you add to get 7 and multiply to get - 8
The two numbers are 8 and - 1.
What is a quadratic equation ?A quadratic equation is of the form ax² + bx + c = 0.It has highest degree of 2 and has two roots.
According to the given question we have to find two numbers that when we add we get 7 and when we multiply we get - 8.
This can be solved by quadratic equation
x² + 7x - 8 = 0.
x =(7±[tex]\sqrt{49 + 32}[/tex] )/2.
x = (7±[tex]\sqrt{81}[/tex] )/2.
x = (7±9)/2.
x = 8 or x = - 1 .
This can also be solved by logic and practice for small numbers like two numbers multiples to - 8 and add to 7.
a + b = 7 and a×b = - 8.
(8×-1) = -8 and ( 8 - 1 ) = 7.

Step-by-step explanation:
If David trips twice every 9 stairs and he has tripped 58 times. We can multiply 9 by 58.
58*9=522
