calculate the time taken for a train to travel 1000m if its initial is 3 m/s and it is moving at a constant acceleration of 0.1m/s^2
Answer:
Step-by-step explanation:
For obects already in motion, the distance travelled, s, is:
s = vi*t + (1/2)at^2
where vi is the initial velocity, a is the acceleration, and t is the time in seconds.
We want the time, t, to reach 1000 meters.
1000 m = (3 m/s)*t + (1/2)*(0.1m/s^2)*(t^2)
(1/2)*(0.1m/s^2)*(t^2) = 0.05t^2
0.05t^2 + 3t -1000 = 0
Solve quadratic equation:
t = 114.6 seconds

Answer:
10
Step-by-step explanation:
1. Any number has a denominator of 1 so you have 6/1 and 8/2.
2. To add you need to make the denominators the same so multiply the 2 to the numerator and denominator of 6/1 which makes 12/2.
3. 12/2+8/2 is 20/2.
4. Simplify 20/2 by dividing the top and bottom by 2 to get 10/1.

There are 15 pieces of the same size candy in a bag. Four are banana flavored, three strawberry flavored, six cherry flavored, and two orange flavored. What would be the probability of picking an orange or a cherry flavored candy from the bag? Round to the nearest tenth.
The probability of picking an orange or a cherry flavored candy from the bag is [tex]\frac{8}{15}[/tex].
Given that, total number of candies=15, banana flavoured candies=4, strawberry flavoured candies=3, cherry flavoured candies=6 and orange flavoured candies=2.
We need to find out what would be the probability of picking an orange or a cherry-flavoured candy from the bag.
What is a probability formula?According to the probability formula, the likelihood that an event will occur is equal to the proportion of favourable outcomes to all outcomes.
The probability of an event[tex]=\frac{Number of favourable outcomes}{Total Number of outcomes}[/tex].
Now, the probability of picking an orange flavored candy from the bag [tex]=\frac{2}{15}[/tex]
The probability of picking a cherry flavored candy from the bag [tex]=\frac{6}{15}[/tex]
The probability of picking an orange or a cherry flavored candy from the bag [tex]=\frac{2}{15}+\frac{6}{15}=\frac{8}{15}[/tex].
Therefore, the probability of picking an orange or a cherry flavored candy from the bag is [tex]\frac{8}{15}[/tex].

Michael started a savings account. After 5 weeks, he had $340 dollars and after 9
weeks, he had $580. What is the rate of change of money in his savings account per
week?
Answer:
$60.00 in his savings account per week
Step-by-step explanation:
First, we can convert the information given into points so we can more easily find the rate of change, or slope:
(5, 340) and (9, 580)
Then, we can subtract the y-values and x-values of both, then divide those differences, to find the slope. Remember that the change in y goes on top of the division problem and the change in x goes on the bottom of the division problem:
(580-340)/(9-5) = 240/4 = 60
So, $60 in his savings account per week.
Answer:
he saves 18.45 dollars in each week
Find an equation for the perpendicular bisector of the line segment whose endpoints
are (8, 7) and (-4,3)
Answer:
y = -3x + 11.
Step-by-step explanation:
The slope of the given line segment is (3-7)/(-4-8) = -4/-12 = 1/3.
The midpoint of the line has coordinates (8-4)/2, (7+3)/2.
= (2, 5).
The slope of the perpendicular bisector = -1/ 1/3 = -3.
So it's bisector has equation:
y - y1 = m(x - x1)=
y - 5 = -3(x - 2)
y = -3x + 6 + 5
y = -3x + 11.

For her grandfather's birthday, Valeria is baking cupcakes. With every egg she can find, she can bake 6 cupcakes.
Write an equation that shows how the total number of cupcakes Valeria can bake, y, depends on the number of eggs she can find, x.
The equation that shows the total number of cupcakes that Valeria can bake will be y = 6x.
Number of cupcakes that can be baked with 1 egg = 6
Let the total number of eggs be represented by x.
Let the total number of cupcakes be represented by y.
Therefore, the total number of cupcakes will then be:
y = 6 × x
y = 6x
Therefore, the equation that shows the total number of cupcakes that Valeria can bake will be y = 6x.
