Answer:
1. the y-intercept is 9.5 and it means the starting length of the candle
2. the slope is -1/2 and it means that the candle burns 1/2 an inch every hour
3. it burns an inch every 2 hours, it is 9.5 inches long, so 19 hours it'll take to burn.
Answer:
tanA=34⟹sinA=332+42−−−−−−√=35
Now, we have
sinAcosA=tanA
⟹3/5cosA=tanA
⟹cosA=13×54×3
⟹cosA=45
⟹cosAsinA=4×35×5=1225
Step-by-step explanation:
Answer:
y - 4= 3/2 (x-4)
Step-by-step explanation:
The answer is B - 43.25
The two congruent sides will have congruent angles. One angle measurement is given. Triangle angles equal 180.
Take 180 and subtract the given angle 93.5. Then divide by 2 to get the measurements x and the other unknown.
180 - 93.5 = 86.5
86.5/2 = 43.25
Answer: zero slope
Explanation: The equation y = -4 can be thought of as y = 0x - 4.
So our line has a slope of 0 and a y-intercept of -4.
This line is a flat line or horizontal.
In fact, when the equation of any line reads y = <em>a number</em>, its slope
will always be 0 because it's a horizontal line.
So, this line has a slope equal to <em>zero</em>.
