We can use the law of sines to solve this problem
sin A sin B
--------- = ----------
a b
sin 81 sin 40
--------- = ---------
x 7
Using cross products
7 sin 81 = x sin 40
Solving for x
7 sin 81 / sin 40 =x
x=10.75599
Rounding to 1 decimal place
x = 10.8

what is the slope-intercept form of the equation of the line that contains the points (1,4) and (0,1)
Answers
Answer:
y = 3x + 1
Step-by-step explanation:
m = ( 1 - 4 ) / ( 0 - 1 ) = 3
( 0 , 1 )
y - 1 = 3(x - 0)
y - 1 = 3x
y = 3x + 1
Answer:
y=3x+1
Step-by-step explanation:
Slope is (y2-y1)/(x2-x1)
therefore slope =
(1-4)/(0-1)
-3/-1
m=3
therefore the equation is
y-y1=m(x-x1)
y-4=3(x-1)
y-4=3x-3

Calvin kicked a soccer ball laying on the ground. It was in the air for 5 seconds before it hit the ground. While the soccer ball was in the air it reached a height of approximately 25 feet. Assuming that the soccer ball’s height (in feet) is a function of time (in seconds), what is the range in the context of this problem?
Answers
Answer:
The range is 0-25 feet
Step-by-step explanation:
Mathematically, when we are talking of the range, we are simply referring to the values at the boundaries.
This refers to the y-axis values. That is the values of the dependent variable
If we are to plot the graph, we will have the time on the x-axis while the amount of time spent in air would be on the y-axis
The base height is from the ground which is marked 0 feet to a maximum height of 25 feet
So the range in the context of this problem is 0-25 feet

What is geometry?One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that Triangle P Q R. Angle Q is 80 degrees and angle P is 35 degrees. Triangle W X Y. Angle W is 35 degrees and angle X is 80 degrees.
The third angle will be calculated as:-
Angle = 180 - 80 - 35
Angle = 65
Therefore, the measure of the third angle in the triangle is 65°. The correct option is B.
