It can be achieved by substituting the formula for length i.e x(A) = A/6 into the formula for Volume.
in the diagram( please mind my writing)
the x(A) is substituted into V(x) .
Only thing left is substitution of the values .
hope this helps .
Answer:
-8/15
Step-by-step explanation:
So remember what sin, cos, and tan are.
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
Now, using what we know of sin and cos, lets find opposite and adjacent to solve for tan.
Sin=-8/17
So this must mean that opposite is -8, and the hypotenuse is 17.
Next, lets find adjacent. Cos = 15/17
So this must mean that adjacent is 15, and again, hypotenuse is 17.
Now lets take the -8 of the opposite, and 15 of the adjacent, and get tan.
<u>Tan: -8/15. </u>
17 is not included in this whatsoever, since hypotenuse is not included in tan. And remember that it cannot be -15/8, since its opposite/adjacent, not adjacent/opposite.
Hope this helps!
If i’m seeing correctly, the cursor is covering a number for the measure of angle BCD. assuming that ABE is the same, as it looks, then it should be the number your cursor is covering.
First thing we are going to do to solve this is to subtract 1.5 from both sides so:
<span>5x+1.5−1.5</span>=<span>7−1.5
</span>5x<span>=5.5
</span>Next we are going to di<span>vide from both sides by 5 so:
</span><span><span>5x/</span>5</span>=<span>5.5/<span>5
Finally your final answer shall be:
</span></span><span>x=1.1
I hope this helps!</span>
X=-5 First u have to distribute the 3 in the parentheses. Second multiple both sides of the equation by 4. Third you move the variable to the left side. Fourth collect like terms. Fifth move the negative from the left side to the right side.
