The depth of diving expressed as signed numbers indicates the magnitude
and direction of Brent and Giselle's displacement in the water.
- The situation expressed as signed number is; <u>-5, -80</u>
Reasons:
The depth Brent decides to go snorkeling = 5 feet below sea level
The depth to which Giselle decides to explore = 80 feet below sea level
Required:
To represent the situation as signed numbers.
Solution:
Taking the sea level as 0, we have;
The depth to which Brent goes = 0 feet - 5 feet = -5 feet
Depth at which Giselle explores = 0 feet - 80 feet = -80 feet
Expressed on the number line, we have;
<u>-∞∣ -80∣ -5∣ 0∣ 5∣ </u>
Therefore;
- The situation expressed as signed numbers is; <u>-5, -80</u>

I think I understand 3 but not the rest of them
Answer:
b ≈ 7.8
Step-by-step explanation:
using the law of sines
∠ A = 180° - 105° - 40° = 180° - 145° = 35° , then
= ( cross- multiply )
b × sin35° = 7 × sin40° ( divide both sides by sin35° )
b = ≈ 7.8 ( to the nearest tenth )
Answer:
(14a+3, 21+4) = 1
Step-by-step explanation:
We are going to use the Euclidean Algorithm to prove that these two integers have a gcd of 1.
gcd (14a + 3, 21a + 4) = gcd (14a+3, 7a + 1) = gcd (1, 7a+1) = 1
Therefore,
(14a + 3, 21a + 4) = 1
