Answer:
4355
Step-by-step explanation:
So first we will see how much is each hour
650 kilometres per hour.
So next we can work out how is 6 hours since that is easy.
650 X 6 = 3900
Next is the 42 mins
All you need to do is
650/ 60 = 65/6
65/6 X 42 = 455
Last step:
3900 + 455 = 4355
Done!
Hope I helped!
Answer:
5,400,000
Step-by-step explanation:
n order to round numbers you must understand the rules for rounds. When looking at a number and deciding whether or not to round up or down, you must look at the number to the right of the target number. Numbers which are four or less round down. Numbers five or more round up to the next value. In the number 5,370,288 the target number is in the hundred thousands place, it is three. Right of the three is a seven. Following the rule, that means we must round up, changing the 3 to a four and all numbers following it to the right must be made zeroes. Your final answer will be 5,400,000.
Answer: 20 Bottles
Step-by-step Explanation:
$71.00 is the total.
$3.55 is for one bottle.
So you have to divide $71.00 by $3.55, to find out how many she can buy. So,
$71.00/$3.00 = 20.
Mrs. Thomas can buy 20 bottles of juice.
Answer: B. g(x) = –4(x – 3)2
Step-by-step explanation: To apply the changes to the equation of a vertical stretch of 4 and a translation of 3 units to the right, as well as the correct answer would be choice B.
The reason for this is when you apply a vertical stretch, because it changes the y-values (which causes it to vertically stretch or appear skinnier when graphed), you would multiply 4 to f(x) which would look like 4x^2.
Then, since you have a reflection over the x-axis, you must multiply a -1 to f(x) to reflect it over the x-axis which would result in -4x^2.
Finally, it also asks to shift the graph right 3 which by moving it right, you change the x values meaning you will perform f(x-3) to achieve this (subtract the value from x when you move right, and add the value to x when you move left).
Answer:
y=5x+3
Step-by-step explanation:
You have the points (1,8) (2,13) (3,18) (4,23)
first you want to find the slope. The equation to find a slope is y2-y1 / x2-x1
your points (1,8) and (2,13) are really all you need
1 would be your x1 and your 2 would be your x2.
8 would be your y1 and 2 your y2
so you want to plug those into your equation y2-y1/x2-x1
13-8 /2-1 you get 5/1
Simplify your answer is 5 for your slope
Now finding the y intercept or "b" I normally just find the pattern of the sequence so in this case when you add one to the top your adding five to the bottom like
x 1 2 3 4
y 8 13 18 23
so to get to your y intercept which is (0,y)
subtract 1 from the top to get zero and subtract 5 from the bottom to get 3 so your y intercept is 3.
Hope this helps.
