Answer:
Triangle A: acute
Triangle B: acute
Triangle C: obtuse
Triangle D: right
Step-by-step explanation:
acute= less than 90 degrees each angle
obtuse=more than 90 degrees for one angle
right=equal exactly 90 degrees for one angle
Answer:
y=-7x+48 slope would be -7
Step-by-step explanation:
Used a Regression Calculator
To solve this we are going to use the half life equation

Where:

is the initial sample

is the time in years

is the half life of the substance

is the remainder quantity after

years
From the problem we know that:



Lets replace those values in our equation to find

:




We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be
91.7 grams.
Given:
y = sinx
Required:
To find the range.
Explanation:
The graph of the sine function is as follows:
We can observe from the graph that the values of y lie between -1 to 1.
So the range of the sinx function is [-1, 1].
Final Answer:
The range of sinx function = [-1, 1].
Answer:
30 and -30 and if that doesn’t work then maybe try -30 first and 30 next
