This is a problem pertaining projectile motion wherein the parameter we're finding is the angle of inclination denoted as theta. The formula to be used is the range:

Range = v^2*sin(2*theta)*(1/g)
100 = (60^2) * sin(2*theta) * (1/32.2)
theta=31.7°

I hope I was able to help you. Have a good day!

Which transformations could be performed to show that △ABC is similar to △A"B"C"? A reflection over the x-axis, then a dilation
amm1812

Answer:

Option D.

Step-by-step explanation:

If two triangles ΔABC and ΔA'B'C' are similar then we take point C of ΔABC to find the transformation performed form C to C'.

Coordinates of C are (0, 3) and the coordinates of C' are (0, -1).

This shows that C is rotated 180° about origin to get the new coordinates as (0, -3) and then new coordinates were dilated by 1/3 which forms C' as (0, -1)

Therefore option D is the correct option.

-2-(+7) is the same thing at -2-7 which is -9

-3 \frac{2}{7} -(- \frac{5}{7} ) is the same thing as (-3 \frac{2}{7}) + (\frac{5}{7}) which is - \frac{18}{7} or -2 \frac{4}{7}

Last but not least the last one is the Associative Property based on definition listed below :)
Associative Property:<span> When three or more numbers are added, the sum is the same regardless of the grouping of the addends. For example (2 + 3) + 4 = 2 + (3 + 4)</span>

An angle measures 50° less than the measure of its complementary angle. What is the measure of each angle?
Lady bird [3.3K]

Answer:

20° and 70°

Step-by-step explanation:

Complementary angles sum up to 90°.

The angle = x

Its complement = x + 50

x + x + 50 = 90

2x = 40

x° = 20°

20+50=70

A can of tuna is shaped like a cylinder.<br> Find its volume to the nearest tenth Use 3.14 for n
Leviafan [203]
The formula for the volume of a cylinder is V=pi*r^2*h 
Since the diameter is 6.8, the radius must be 3.4 (6.8/2)
We can then plug in the given values to solve for the volume
V=3.14*3.4^2*4
V=3.14*11.56*4
V=145.2 so B

Hope this helps
