Answer:
Explanation:
Use the equation

where h(t) is the height after a certain amount of time goes by, v0t is the initial upwards velocity, and h0 is the initial height of the projectile. For us:
h(t) = 10
v0t = 80
h0 = 3 and filling in:
and get everything on one side to factor:

This factors to
t = .09 sec and 4.9 sec. Let's interpret this.
The time of .09 is when the ball reached 10 feet on the way up, and
the time of 4.9 is when the ball reached 10 feet on the way back down. That's the height we need, 4.9 seconds.
Answer:
The distance of the image produced by the concave mirror is 11.27 cm.
Explanation:
Given that,
Focal length = 8.40 cm
Distance between object and plane mirror = 11.0 cm
Distance between plane mirror and concave mirror = 22.0 cm
We need to calculate the object distance

We need to calculate the distance of the image
Using formula of distance of the image

Where, u = Object distance
f = focal length
Put the value into the formula


Hence, The distance of the image produced by the concave mirror is 11.27 cm.

Explanation:
Given parameters:
length range of adult mosquito = 3.0 - 6.0mm
Smallest mosquito = 2.5mm
Largest mosquito = 19mm
Average mass range = 3.0 - 5.0mg
Unknown:
Length of largest known mosquito in inches = ?
Solution;
The length is the longest dimension. It is how long a body is.
The problem here is converting from mm to inches;
The length of the longest mosquito which is the largest is 19mm
19mm to inches;
1mm = 0.039inches
19mm = 19mm x
= 0.74in

Answer:
1 cm = 0.131 daks
Explanation:
It is given that,
1 dak = 3 inches
and
1 inch = 2.54 cm
We need to find how many "daks" are there in a centimeter. We can do the conversions as follows :



1 cm = 0.131 dak
So, there are 0.131 daks in 1 centimeter. Hence, this is the required solution.
<u>The number of variations the dealership have is 40 cars</u>.
Data given;
- The number of different product = 4
- The number of transmission = 2 (standard or automatic)
- The numbers of colors available = 5
<h3>Dealership variation </h3>
This is the total numbers of cars available in the dealer shop at the moment.
To get that, we simply multiply the numbers of colors available, the number of transmission and the makes of car available.
This is equal to

From the above calculation, we can say that <u>the variations the dealership offers is 40</u>
