Answer:
Step-by-step explanation:
1)a) Abscissa of O 0
Abscissa of A 4
Abscissa of B -3 {opposite of 3}
Abscissa of C 3 {3 is the only positive integer like A}
Abscissa of D -4.5
Abscissa of E -6
Abscissa of F -1 {Midpoint of AE = (6+4)/2 = 10/2 = 5th number from -6 or 4}
b) OB = 3 units
DA = 8.5 {4.5 +4 = 8.5}
Answer:
C. 40%
Step-by-step explanation:
There was a total of 30 girls surveyed. Out of those 30 girls 12 prefered soccer to baseball. 30/12 = 0.4 which is equivalent to 40%.
The answer would be tan (44).
For sin (75)
The answer will be computed this way:
sin 75º = sin (30)º + 45º= sin 30 cos 45+cos 30 sin 45= 1/2*√2/2+√3/2*√2/2=√2/4+√6/4=(√2+√6)/4Check with calculator:sin 75º ≈ 0.9659
For tan (44): checking with the calculator the answer is also: ≈ 0.9659

Answer: approximately <u>188.07</u> feet
======================================================
Explanation:
Refer to the diagram below. Note that the 62 degree angle is from the fact that 90-28 = 62.
With the reference angle 62 degrees in mind, we have an unknown opposite side x feet and a known adjacent side 100 feet.
Use the tangent trig ratio to tie the two sides together, and then solve for x.
tan(angle) = opposite/adjacent
tan(62) = x/100
100*tan(62) = x
x = 100*tan(62)
x = 188.072646534633 approximately
x = 188.07 feet approximately
Your calculator needs to be in degree mode. One way to check is to compute something like tan(45) and the result should be 1.
