Answer:
• Consider points (2, 0) and (0, 6) spotted from the graph.
• substitute:
I belive the answer is 28.
When you're doing scientific notation you move the decimal between two numbers to make the numer between 1-9.
a)
in this case you have 12,820,000 you move the decimal between 1 and 2 so you have 1.282 then you count the number of places you've moved the decimal, which is 7, therefore your answer is 1.282×10 to the 7th power.
b)
since its 3.5 times further you multiply 12,820,000 by 3.5 and you get 44,870,000. so you don the same thing you did before you move the decimal between 4 and 4, so you get 4.487 and since you moved the decimal and since you've moved that 7 places also you get 4.487×10 to the seventh power
it's easy once you understand it but mainly you've got to move the decimal in between two numbers, which is less than 9 and greater than 1.
Answer:
The equation for this stretch of roadway in point-slope form is
Step-by-step explanation:
Equation in point-slope form:
The equation of a line in point-slope form is given by:
In which is the point and m is the slope.
A stretch of highway has a 4% uphill grade. This means that the road rises 1 foot for every 25 feet of horizontal distance.
This means that
The beginning of the highway (x = 0) has an elevation of 2,225 feet.
This means that . So
The equation for this stretch of roadway in point-slope form is
Answer:
Direct Variation:
- The number of family members are directly expenditures.
- The number of fruit in kg directly proportional to price of fruit.
- The number of selling products directly proportional to profit.
- The distance covered by body directly proportional to speed of body
- The acceleration produce in car directly proportional to change in velocity
- The income is directly proportional to working hours.
- The cost of electrical bill directly proportional to number of fans running in the house.
- The quantity of water fill in tank is directly to time for which the motor is switch on.
- The marks in study is directly proportional to hardworking.
- The bank balance is directly proportional to amount of saving.
Inverse Variation:
1. The bank balance is inversely proportional to expenditures.
2. The number of family members (which not work) are inversely proportional to amount of saving.
3.The working days required to complete the work are inversely proportional to number of labors.
4. The velocity of body is inversely proportional to time.
5. The acceleration is inversely proportional to time.
6. The acceleration of body is inversely proportional to mass of body.
7. The number of student fail in the class is inversely proportional to number of qualify teachers and hardworking.
8. The battery power is inversely proportional to time for which it used.
9. The ability of do work hard is inversely proportional to age of man after youngness to onward.
10. The number of mistake in work is inversely proportional to practice.
Explanation:
<u>Direct Variation</u>: A <u>relationship</u> where one quantity is a constant multiplied by another quantity is called <u>direct variation</u>.
<u>Inverse Variation</u>: <u>Inverse variation</u> is defiend as the relationship between two variables in which the resultant product is a constant. If a is inversely proportional to b, the form of equation is a = k/b, where k is constant. Inverse variation is known as the opposite of direct variation. If there an increas ein one variable, the other variable decreases in proportion so that the resultant product remains unchanged.
