Answer:
ΔB
Step-by-step explanation:
ΔA's angles are: 58º, 54º, and 68º
68º is found by 180 - (58 + 54)
ΔB's angles are: 54º, 68º, and 58º
58º is found by 180 - (68 + 54)
ΔA and ΔB have the same angles, therefore they are similar triangles
To get the slope, we will need two points that belong to the line.
From the graph, we can get two points as follows:
(0,-1) and (-1,1)
The slope of the curve can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)
Substitute with the two points to get the slope as follows:
slope = (1--1) / (-1-0) = (2) / (-1) = -2
It is a little difficult to see the graph but I am assuming that the x-axis is temperature in Celsius and the y-axis is temperature in Fahrenheit.
Since the y-intercept is always the point at which the x-value is equal to 0, in this case the y-intercept would be the Fahrenheit temperature that is equivalent to 0°C.
I hope this helps.
Answer:
direct relation between distance travelled by a train and its speed, when time is constant.
Step-by-step explanation:
We know that the speed of an object is the total distance covered divided by total time taken. Mathematically, it is given by :
Where
d is distance
t is time taken
It can be seen that relation between the distance and the speed is direction. Hence the correct option is (a) "direct".
The temperature fell by 24 degrees in 6 hours. We need to find out how many degrees did the temperature fall every hour.
You can <u>divide</u> 24 with 6.
24 ÷ 6 = 4
Your answer is 4
hope this helps!
