Answer:
38feet high
Step-by-step explanation:
Given the following
Length of the string = 40feet (hypotenuse)
Angle of elevation = 71 degrees
Required
Height of the kite (opposite)
Using the SOH CAH TOA identity
Sin theta = opp/hyp
Sin 71 = H/40
H = 40sin 71
H = 40(0.9455)
H = 37.82
Hence the kite is 38feet high (to the nearest whole number)
Answer:
yes and no
Step-by-step explanation:
Collinear points can be coplanar because a plane is defined by <u>three</u> points not on the same line, and a line is defined by <u>two </u>points so you have another point which makes this statement true.
Coplanar points can not be collinear because in a plane all three points cannot be on the same line and to be collinear they would have to be.
Answer:
60 mph
Step-by-step explanation:
It takes two minutes to drive one mile at 30 mph. You are planning on covering two total miles. If your average speed is 60 mph, it would take two minutes to cover these two miles. So you have to go 60 mph.
Hope This Helps :)
To figure out what expression we can write to represent the situation, we need to turn the word problem into mathematical functions.
The word "more" means we are adding. The word "times" means we are multiplying.
So the expression should be 4x+10 where x represents the minutes Brianna spent studied.
Answer:
-25
Step-by-step explanation: When you multiply to negatives together you get a positive thus being shown in the problem -5 times -1 =5 then you multiply 6 times -5 and whenever you multiply a positive number by a negative you'll always get a negative number so 6 times -5 =-30 then you add 5 and -30 and you get -25. I hope this is right :D
