Answer:
0
Step-by-step explanation:
tan2°- cot 88° = tan 2° - tan (90-88)°
= tan 2°-tan 2° = 0
The first thing you should do is draw the ACB scalene triangle and name the vertices and distances. We will denote the vertices with capital letter and the distances with minuscules. Then, you must draw a triangle that is similar, in this case, ADB. Finally prove the Pythagorean theorem.I attach the solution.
Answer:
a²+b²=c²; (1.0)²+(5.0)²=x²
Step-by-step explanation:
(1.0×1.0)+(5.0×5.0)=(x×x)
Answer: C. f(x)=1.5x
Step-by-step explanation:
Here's the complete question:
In a direct variation equation f(x) = 6 when x = 4. what is the direct variation equation
A-f(x)=6x
B-f(x)=4x
C-f(x)=1.5x
D-f(x)=0.67x
The direct variation equation will be:
6 = kx
When x = 4, this will be:
6 = 4k
k = 6/4
k = 1.5
Therefore, the direct variation equation is: f(x)=1.5x
Surface area = 2(lw) + 2(wh) + 2(lh)
2(4 * 5) + 2(5 * 15) + 2(4 * 15)
2(20) + 2(75) + 2(60)
40 + 150 + 120
310 square inches
