Answer:
24
Step-by-step explanation:
We are given the logarithmic expression:
We are also given by the problem that:
From the expression, we will simplify it using two properties:
Therefore, apply the properties to simplify:
Next, we will use another property to take an exponent as a coefficient:
Hence:
Substitute what are given in the problem and the answer will be:
Hence, the answer is 24.
for the second pair of angles, the angle of reference is really about 26.57°. Now, the tangent is only negative in two quadrants, the II and IV Quadrants, using the angle of reference, it'd give us those angles.
Make sure your calculator is in Degree mode.
Answer:
a.
b.
Step-by-step explanation:
a. You know that the dimensions of Rectangle A are
Since Rectangle B’s dimensions are (which is 0.6 cm) larger than Rectangle A’s dimensions, then the dimensions of Rectangle B are:
Since Rectangle C’s dimensions are (which is 0.6 cm) larger than Rectangle B's dimensions, then the dimensions of Rectangle C are:
The find the total area of all three rectangles you must add the products obtained when you multiply their dimensions. Then:
b. The perimeter of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width.
Knowing the dimensions of each rectangleg, you can calculate the total perimeter as follows:
Then, if a 40-cm coil of wire was used to form the rectangles, the amount of wire that is left is:
