Answer:
B. 14 m sq.
Step-by-step explanation:
Area for a triangle
A = W times H times 1/2
4 times 7 = 28
28/2 = 14
The 60 represents the rate at which the train is traveling in km per hour. So, I believe the answer would be D (sorry if this is wrong, to be honest I’m just using context clues)
Answer:
x = - 7
Step-by-step explanation:
Using the rule of exponents
×
= 
Given
×
= 6², then
= 6²
Since the bases on both sides are equal then equate the exponents
9 + x = 2 ( subtract 9 from both sides )
x = - 7
Answer:
g = 1000K
Formula: Multiply the amount of kilograms with 1000 to convert it into grams
Step-by-step explanation:
Kilo stands for 10³ or 1000. So, a kilogram means one thousand grams. This means that if you ever want to get back to grams from kilograms, all you need to do is multiply the number of kilograms by 1,000.
Number of grams = Number of kilograms x 1000
g = 1000K
Answer:
1. No.

Since f(1)=f(3) and
then f isn't one-to-one.
2. No

Since f(0)=f(2) and
then f isn't one-to-one.
3. No

Since f(0)=f(2) and
then f isn't one-to-one.
4. Yes

Since
, then f is one-to-one
5. Since f(1)=f(3) and
then, f isn't one-to-one
