Answer:
9
Step-by-step explanation:
If the sine of an angle is equal to the cosine of an angle, that means that the sides adjacent and opposite to that angle are equal. One triangle that has two equal sides is an isosceles triangle. We can set this triangle to be a 45-45-90 degree triangle, which means that the angle would be 45.
Now, we have to find the value of
and
The tangent of 45 is 1, so 1 squared times 4 is 4.
We have .
Again, the tangent of 45 is 1, and 1 times 5 is 5.
We have
5 + 4 = 9
Answer:
Step-by-step explanation:
The distributive property is for example 3(2*4) the outside number multiplies everything inside the parenthesis. For the communitive, its like opposites, but they give the same answer, for example 4*5, 5*4. And for associative is like the distributive property, but not at the same time, for example, (a*b)*c = a*(b*c) it has the numbers, but pluged in in another type of way
Hope this helps!

Answer:
440 m
Step-by-step explanation:
We are to assume that Time is measured from the beginning of Amir's drive. So the altitude at the beginning of Amir's drive is the altitude corresponding to Time = 0. That is the point at the left side of the graph where the blue line meets the vertical axis.
The number on the vertical axis at that point is 440, and the label tells us that is meters of altitude. Amir's altitude at the beginning of his drive is 440 meters.
The formula for direct variation is y = kx<span> where k </span>≠ 0
y = 9/x is an inverse relation
