Answer:
Step-by-step explanation:
Numbers 1 and 4 are perimeter questions so all you do is add up all the sides and the label is cm. For #2, this is an area problem and the area for a rectangle is length times width, so multiply the 2 together and the label is inches squared. For #3, the volume formula for a cube is side*side*side and the label for this is feet cubed. For #5, the area for a triangle is .5 times the base times the height, and the label is mm-squared. That should help you get all the answers on your wn. Very, very simple.
Answer:
x = 0
y = -4
negative 4 cuz the line goes down, meaning it's negative
Answer:
7/3 in decimal form it's 2.3 repeated
Step-by-step explanation:
6 sec can take penny to strike the ground.
Solution:
Given data:
feet
feet
Re-arrange the terms from greatest degree to smallest degree.
We can solve it by applying quadratic formula,
Here a = –16, b = 48, c = 288
Now, write find two t's using plus and minus operation.
t = –3 (or) t = 6
We cannot write time is negative. so neglect t = –3.
Therefore t = 6.
Hence 6 sec can take penny to strike the ground.
Answer:
-84 + 10i
Step-by-step explanation:
Standard Complex Form: a + bi
Step 1: Evaluate
√-100 = √-1 x √100 = i x 10 = 10i
-84 = -84
Step 2: Combine
10i - 84
Step 3: Rearrange
-84 + 10i
