use the pythagorean theorem: a^2 + b^2 = c^2
6^2 = 36
4^2 = 16
36-16 = 20.
the square root of 20 is either a.) the square root of 20 or b.) 4.4721... (rounded 4.5)
Answer:
C
Step-by-step explanation:
Here, we want to find an equation in the options which is same as the equation given in the question;
The equation we are testing against is;
0.05n + 0.1d = 3.65
What we can do here is divide through by 0.01
So we will have;
0.05n/0.01 + 0.1d/0.01 = 3.65/0.01
= 5n + 10d = 365
9514 1404 393
Answer:
x = 78°
Step-by-step explanation:
The sum of the interior angles of a triangle is 180°.
x + a + b = 180°
x = 180° -a -b . . . . . . . . add -a-b to both sides
x = 180° -54° -48°
x = 78°
From points A and B, the distance between which is 1020 mi
The speed of one train was 10 mph greater than the speed of the other one
Let the Speed of first train is x
Speed of second train is x+ 10
Time = 5 hours
Distance = speed * time
Distance traveled by first train = x * 5= 5x
Distance traveled by second train = (x+10) * 5= 5x + 50
the trains had not met yet and were 170 mi apart.
the distance between A and B is 1020 mi, Distance traveled by two trains = 1020 - 170 = 850 miles
Distance traveled by first train + second train = 850
5x + 5x + 50 = 850
10x + 50 = 850
Subtract both sides by 50
10x = 800
x= 80
Speed of first train is 80 miles per hour
Speed of second train is 90 miles per hour
A function assigns the values. The correct option is D.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given the function h(x)=3√(x+1) - 2, therefore, if we plot the function on the graph, then the statement that is true about the function is that the function is increasing on the interval (–1, ∞).
Hence, the correct option is A.
