One thing I want to clarify for you, It's Evaluate, not Avaluate.
Okay so, we want to find the value of 2^3x-1 and we know x = 1.
You didn't really clarify if the expression was or
, so I'll be doing both:
For , we should plug in x to get
and then simplify to get
.
2 to the power of 2 or is equal to 2 * 2 or 4.
The second one, , we should plug in x to get
and then to become
. 2 to the power of 3 or
is 8 and then minus 1 is 7.
Hello!
First of all, let's find the triangle. As we can see, it is eight units long and four units tall. We can use the triangle formula and half the product.
4(8)=32
32/2=16
Now we need to find the area of the semicircle. We can use circle formulas and half our final answer. We will find the area using A=r².
We know that the diameter of this circle is eight. Therefore our radius is 4.
A=²
A=
Now we multiply.
16≈50.27
Now we add our triangle.
50.27+16=66.27
The nearest answer to this is B)66.2. It may have been a bit over as we used , not 3.14.
I hope this helps!
