Answer:
x = 8*root3
y = 16
Step-by-step explanation:
You can use tangent and cosine of 60° to find x and y, BUT THERE'S A SHORTCUT. You pointed out that its a 30°-60°-90° triangle. That is a special right triangle. Here's the shortcut:
the longest side (hypotenuse) is double the shortest side. We have an 8 on the shortest side, so the hypotenuse (longest side) is 16. This ALWAYS works for 30°-60°-90° triangles!
Another shortcut:
The longer leg is the shorter leg × root3.
This ALWAYS works on 30°-60°-90° triangles.
So on your triangle, the short side is 8, that means the longer leg is 8×root3.
ta-daaaa!
3/7 is the answer for this question
50% of 620 is half of 620.
Writing 50% of 620 is 50%. (Or 310 if you wanted to know half of 620)
The x-value of -7 shows up more than once in relation ...
B. X -7 -5 -7 2 Y 34 32 40 34
_____
When there is more than one y-value for an x-value, the relation is NOT a function.
Answer:
1
Step-by-step explanation:
The number of terms in the polynomial;
7b^7
The number of terms in this polynomial is simply 1
Since the two are together, they are treated as a single term in the polynomial.
Take for example a quadratic polynomial;
3x^2 + 2x + 1
This is a polynomial with 3 terms.
All multiplications are treated as a single unit.
This is the case in terms of what we have too
